B2 adjective #1,000 最常用 16分钟阅读

broadcast

At the A1 level, the word 'broadcast' might seem a bit difficult, but you can understand it simply as 'on TV' or 'on the radio.' When we talk about 'broadcast media,' we are talking about the big TV channels and radio stations that everyone can watch or listen to for free. Imagine you have a television in your house. When you turn it on and see the news or a cartoon, that is a broadcast. It is a message or a show that is sent to many people at the same time. You don't need to pay for a special website to see it; it is just 'in the air.' In simple English, we use this word to describe the type of media. For example, you might say, 'I like broadcast TV because it is free.' Or, 'My dad listens to broadcast radio in the car.' At this level, you don't need to worry about the technical details. Just remember that 'broadcast' means 'sent to everyone.' It is like a teacher speaking to the whole class at once. The teacher is 'broadcasting' their voice. If the teacher whispers to only one student, that is NOT a broadcast. So, when you see the word 'broadcast' before another word, like 'broadcast news,' it just means news that you see on your TV screen at home. It is a very useful word to know when you are talking about your hobbies or how you get information. You can also think of it like a big shout. If you shout 'Hello!' in a park, that is a broadcast because everyone can hear you. If you send a text message to one friend, that is private. 'Broadcast' is for the public. Even at A1, you can start using it in simple sentences like 'I watch broadcast news every morning.' This helps you sound more like a native speaker who knows the right words for different types of media.
At the A2 level, you can start to use 'broadcast' as an adjective to describe specific things you see or hear. You are learning to talk about your daily life and the world around you in more detail. 'Broadcast' is a great word for this. You might use it to describe your favorite type of journalism. For example, 'I want to study broadcast journalism because I like being on camera.' Here, 'broadcast' describes the kind of journalism that happens on TV or radio, not in a newspaper. You can also use it to talk about technology. If you are buying a new TV, you might ask if it can receive 'broadcast signals.' This means the signals that come through the air from a big tower. At this level, you should also know that 'broadcast' is different from 'cable' or 'internet.' Cable TV comes through a wire, and internet TV comes through your computer. Broadcast TV comes through the air to an antenna. Using the word 'broadcast' helps you be more specific. Instead of just saying 'TV,' you can say 'broadcast television' to show you mean the free channels. You might also hear this word in the news. If there is a big storm, the government might send a 'broadcast alert' to everyone's phone. This is a special message for the whole city. It is called 'broadcast' because it goes to everyone at the same time. Another way to use it is in the phrase 'broadcast quality.' If you are making a video for school, you might want it to be 'broadcast quality,' which means it looks very professional, like something you would see on a real TV channel. By using 'broadcast' as an adjective, you are showing that you understand how information is shared in the modern world. It is a step up from basic words like 'TV' or 'radio' and helps you describe the media industry more accurately.
At the B1 level, you are becoming more comfortable with professional and topical vocabulary. 'Broadcast' as an adjective is very common in discussions about media, technology, and society. You should understand that it refers to a 'one-to-many' model of communication. This means one person or company sends a message to millions of people at once. This is different from 'social media,' where many people talk to many other people. You can use 'broadcast' to discuss the history of media. For example, 'Before the internet, broadcast media was the main source of news for most people.' This sentence uses 'broadcast' to categorize an entire era of communication. You can also use it to talk about the quality of something. In a job interview for a media company, you might say, 'I have experience producing broadcast-ready content.' This tells the employer that your work is good enough to be put on television immediately. It is a very professional way to speak. You should also be aware of 'broadcast rights.' This is a big topic in sports. You might say, 'The broadcast rights for the Olympics are very expensive.' Here, 'broadcast' describes the legal right to show the games on TV. At this level, you can also start to use the word in more abstract ways. For example, a 'broadcast email' is an email sent to everyone in a large organization. Even though it's not radio or TV, we use the adjective 'broadcast' because the style of communication is the same: one message for everyone. Understanding this 'style' of communication helps you use the word in many different contexts. You might also encounter 'broadcast standards,' which are the rules about what can be shown on TV. If a show is too violent, it might not meet 'broadcast standards.' Using these phrases correctly will make your English sound much more advanced and nuanced.
At the B2 level, you are expected to use 'broadcast' with precision in both formal and informal contexts. You should understand the nuances that distinguish 'broadcast' from other forms of distribution like 'streaming' or 'narrowcasting.' As an adjective, 'broadcast' often implies a certain level of public accountability and regulation. For instance, 'broadcast journalism' is often subject to stricter rules about fairness and accuracy than 'online journalism' because it uses public airwaves. You can use this in an essay: 'The decline of traditional broadcast networks has led to a more fragmented media landscape.' Here, 'broadcast' is essential for defining the specific type of network you are talking about. You should also be familiar with technical collocations like 'broadcast bandwidth' or 'broadcast spectrum.' These terms are common in discussions about technology policy and the digital divide. For example, 'The government is reallocating part of the broadcast spectrum for 5G mobile services.' This shows a high level of vocabulary because you are using 'broadcast' to describe a specific physical and legal resource. Furthermore, you can use 'broadcast' to describe the reach of a signal. 'The station's broadcast range was limited by the mountainous terrain, leaving many rural communities without access to local news.' In this sentence, 'broadcast' modifies 'range,' providing a clear technical description. You should also be careful with the grammar; remember that 'broadcast' is its own adjective and past participle form. Avoid saying 'broadcasted media.' Using the correct form consistently is a hallmark of the B2 level. You can also use the word to describe the 'tone' of a communication. A 'broadcast style' of speaking is often clear, authoritative, and intended for a general audience. By mastering these different applications, you demonstrate a deep understanding of how the word functions within the specialized fields of media and technology.
At the C1 level, your use of 'broadcast' should reflect a sophisticated understanding of media theory and technical infrastructure. You should be able to use the adjective to critique the societal impact of different communication models. For example, you might discuss the 'broadcast era' as a period of cultural homogenization, where a few major networks defined the national conversation. Using 'broadcast' in this way treats it as a historical and sociological descriptor. You should also be comfortable using it in highly technical or legal contexts. Consider the phrase 'broadcast indecency.' This is a specific legal term in the United States referring to content that violates community standards on the airwaves. A C1 speaker might say, 'The court's ruling on broadcast indecency has significant implications for First Amendment rights in the digital age.' Here, 'broadcast' is not just a description of a TV show; it is a legal category that determines which laws apply. You can also use 'broadcast' to describe the architecture of a network. In computer science, a 'broadcast domain' is a logical division of a computer network where all nodes can reach each other by broadcast at the data link layer. Using such specialized terminology correctly shows a high level of professional English. You might also explore the metaphorical uses of the word in literature or high-level rhetoric. A 'broadcast seed' approach to marketing might be criticized for its lack of efficiency compared to data-driven targeting. In this context, 'broadcast' serves as a sophisticated metaphor for an indiscriminate, wide-reaching strategy. Your ability to switch between these technical, legal, and metaphorical uses—while maintaining perfect grammatical accuracy—is what defines the C1 level. You understand that 'broadcast' is not just about TV; it is about a fundamental philosophy of communication that prioritizes mass reach over individual targeting.
At the C2 level, you possess a near-native command of the word 'broadcast' and can use it with absolute precision across all domains. You are aware of the word's deep etymological roots in agriculture and can use this knowledge to enrich your writing or speech. For instance, you might draw a parallel between the 'broadcast sowing' of the 18th century and the 'broadcast dissemination' of information in the 20th century, noting how both rely on a certain level of 'productive waste'—sending out more than is strictly necessary to ensure that enough 'takes root.' This level of nuance allows you to use the word in philosophical discussions about the nature of the public sphere. You might argue that the 'broadcast model' of communication was essential for the functioning of 20th-century democracy because it provided a 'common square' of shared information, a concept that is being eroded by the 'narrowcast' algorithms of social media. In this context, 'broadcast' is a powerful adjective that carries significant weight. You are also perfectly comfortable with the most technical applications of the word, such as 'broadcast storm' in networking or 'broadcast delay' in live production, and you can explain these concepts to others using precise language. Your grammar is flawless; you never slip into using 'broadcasted' as an adjective, and you intuitively know when 'broadcast' is the most appropriate word versus 'transmitted,' 'aired,' or 'circulated.' You might even use the word in a playful or ironic way, such as describing a person's loud, public conversation on a cell phone as a 'broadcast-style intrusion' into a private space. This ability to use the word both as a precise technical descriptor and a flexible rhetorical tool is the hallmark of a C2 speaker. You see 'broadcast' not just as a word, but as a concept that has shaped the modern world, and you can deploy it to express complex ideas with clarity and elegance.

broadcast 30秒了解

  • Broadcast as an adjective describes anything related to the mass distribution of audio or video content via radio, television, or digital signals.
  • It is commonly used in professional terms like broadcast journalism, broadcast quality, and broadcast rights to specify the medium of communication.
  • The term implies a 'one-to-many' model, where a single source reaches a wide, public audience simultaneously without individual targeting.
  • Beyond media, it can also describe the physical scattering of things like seeds or data packets across a wide area or network.

The word broadcast, when used as an adjective, describes anything related to the transmission of programs or information via radio, television, or digital signals intended for a wide, public audience. While we often think of it as a verb (to broadcast a show), the adjective form is essential for categorizing industries, technologies, and professional standards. It originates from an old agricultural practice of 'broad-casting' seeds—literally throwing them in a wide arc over a field rather than planting them in neat rows. This metaphor perfectly captures the essence of modern broadcast media: information is 'scattered' across the airwaves for anyone with a receiver to catch. In contemporary English, you will encounter this adjective most frequently in professional contexts like broadcast journalism, broadcast engineering, or broadcast rights. It implies a sense of scale and public accessibility that distinguishes it from narrowcasting or private communications.

Broadcast Media
This refers to the collective group of radio and television stations that distribute content to the public. Unlike print media, broadcast media relies on electromagnetic spectrums or digital streams to reach the audience instantaneously.
Broadcast Quality
A technical term used to describe audio or video that meets the high standards required for professional transmission. If a video is 'broadcast quality,' it means it is clear, stable, and high-resolution enough to be shown on national television.
Broadcast Standards
The set of ethical, legal, and technical rules that govern what can be aired. This includes regulations on language, decency, and signal interference.

The local station lost its broadcast license after failing to comply with federal regulations regarding public service announcements.

Example of 'broadcast' modifying a noun to indicate legal status.

Beyond the technical realm, the adjective can also describe the physical act of scattering. In botany or gardening, a broadcast application of fertilizer means spreading it evenly over the entire surface of the soil rather than placing it in specific holes. This usage remains true to the word's 18th-century roots. However, in 99% of modern conversations, you will be using it to talk about the media. It is a formal yet common term, appearing in business reports, news articles, and academic discussions about communication. When you hear someone talk about 'broadcast news,' they are specifically referring to news delivered via TV or radio, often contrasting it with 'digital-first' or 'print' news. This distinction is becoming more fluid in the internet age, but the term 'broadcast' still carries a weight of authority and mass-reach that 'online' sometimes lacks.

We need to ensure the audio is broadcast ready before we go live at six o'clock.

In the world of sports, the term broadcast rights is a multi-billion dollar topic. These are the legal permissions sold by sports leagues to networks, allowing them to show games. When a company buys 'broadcast rights,' they are buying the exclusive ability to put those images on the air. This shows how the adjective functions to define ownership and distribution channels. Furthermore, the term is used in emergency management, such as a broadcast alert, which is a message sent out to every device or receiver within a certain area simultaneously. This highlights the 'wide' aspect of the word—it isn't a message for one person, but for everyone within the signal's reach.

The broadcast range of this transmitter is approximately fifty miles in every direction.

Using broadcast as an adjective requires placing it before a noun to describe its nature or function within the realm of mass communication. It acts as a classifier, narrowing down the type of technology, professional field, or legal framework being discussed. Because it is a 'functional' adjective, it rarely takes comparative or superlative forms; something is either 'broadcast' or it isn't—it's rarely 'more broadcast' than something else. To master its use, focus on the common pairings that have become standard in English. These pairings, known as collocations, are the most natural way to integrate the word into your vocabulary. For instance, 'broadcast television' is a specific term used to distinguish free, over-the-air TV from cable or streaming services. By using the adjective, you provide immediate clarity to your listener about the delivery method of the content.

Broadcast Journalism
She decided to major in broadcast journalism because she preferred the fast-paced environment of television news over writing for newspapers.
Broadcast Signal
The mountain range interfered with the broadcast signal, causing static for many residents in the valley.
Broadcast Network
The major broadcast networks are seeing a decline in viewership as more people switch to on-demand streaming platforms.

The documentary was produced to broadcast standards, ensuring it could be sold to international TV stations.

When writing formally, the adjective broadcast helps maintain a professional tone. In business or legal documents, you might see phrases like 'broadcast territory' or 'broadcast window.' A 'broadcast window' refers to the specific period during which a network has the right to air a program. Using the adjective here is much more precise than saying 'the time they can show it.' In technical writing, you might describe a 'broadcast storm' in computer networking, which is when a network is overwhelmed by too many broadcast packets being sent at once. This shows the word's versatility across different fields of expertise. Even in these technical settings, the core meaning remains: one-to-many distribution.

The broadcast industry has undergone massive changes since the introduction of digital high-definition signals.

In casual conversation, the adjective is less common than the verb, but it still appears when discussing career paths or technology. You might say, 'I'm looking for a broadcast-quality microphone for my podcast,' implying you want something good enough for professional radio. Here, the adjective serves as a benchmark for quality. Another common use is in 'broadcast news,' which distinguishes the style of reporting from 'print news.' Broadcast news tends to be more concise and focused on visual or auditory impact. Understanding these nuances allows you to choose the word that best fits the context of your communication, whether you are discussing a career in the media or the technical specifications of a new piece of equipment.

Many rural areas still rely on broadcast radio for emergency updates when the internet goes down.

Finally, consider the word's use in the phrase 'broadcast seeding.' This is a specific agricultural term where seeds are scattered over a large area. While this is the original meaning, it is now considered a specialized or 'niche' use of the adjective. If you are a gardener or a farmer, you might use this to describe how you plant grass or wildflowers. In this context, 'broadcast' describes the method of distribution, emphasizing the wide, random pattern of the seeds. This helps to visualize why the word was eventually chosen to describe radio and television: the signals are 'scattered' across the sky in the same way seeds are scattered across a field, hoping to land where they can grow (or in the media's case, where they can be heard).

The word broadcast is a staple of the media and technology sectors, making it a common term in professional environments, newsrooms, and academic settings. If you walk into a television studio, you will hear it constantly. Producers talk about 'broadcast schedules,' engineers monitor 'broadcast signals,' and lawyers negotiate 'broadcast contracts.' It is the language of the industry. However, you don't have to be a media professional to encounter it. It is frequently used in the news itself, especially when reporters are discussing the state of the media or reporting on new regulations from government bodies like the FCC in the United States or Ofcom in the UK. These organizations are often referred to as 'broadcast regulators,' highlighting the adjective's role in defining legal jurisdictions.

In the Newsroom
'We have a broadcast delay of seven seconds to ensure no inappropriate content accidentally airs during the live interview.'
In a University
'The communications department offers a specialized track in broadcast media for students interested in television production.'
In a Tech Store
'This antenna is designed to pick up digital broadcast signals from up to sixty miles away, providing free access to local channels.'

The broadcast booth at the stadium was filled with commentators preparing for the championship game.

You will also hear the word in the context of public safety. During natural disasters or national emergencies, governments use 'broadcast alerts' to reach the entire population. These are the loud, buzzing sounds that come through your phone or television. In these moments, the 'broadcast' nature of the communication is its most important feature: it is a one-to-all message designed for maximum reach. This usage reinforces the idea of 'broadcast' as something that covers a wide area simultaneously. Similarly, in the world of corporate communications, an executive might send a 'broadcast email' to every employee in the company. While this is a digital use, the adjective 'broadcast' is used to describe the 'one-to-many' distribution style of the message.

The president's broadcast address was watched by millions of citizens across the country.

In the creative industries, 'broadcast' is a term of prestige. Filmmakers and content creators strive for 'broadcast quality' because it signifies a level of professionalism that is acceptable for major networks. If you are looking at equipment reviews online, you will see 'broadcast' used to describe high-end cameras, microphones, and editing software. For example, a 'broadcast monitor' is a very expensive, highly accurate screen used by colorists to ensure the colors in a movie look perfect when they are aired. In this sense, 'broadcast' is almost synonymous with 'professional grade.' It sets a standard that hobbyist equipment often fails to meet. Hearing the word in this context tells you that the subject is serious, high-quality, and intended for a mass audience.

The network is looking for broadcast partners to help distribute the new series in European markets.

Finally, in the world of computer science and IT, 'broadcast' is a technical term for a type of network communication. A 'broadcast address' is a special network address that allows data to be sent to all devices on a network at once. If you are studying for an IT certification, you will spend a lot of time learning about broadcast domains and how to manage broadcast traffic. In this highly technical setting, the word retains its core meaning of 'sending to everyone.' Whether you are in a cornfield, a TV studio, or a server room, 'broadcast' always points to the same concept: a wide, inclusive distribution of something—be it seeds, stories, or data packets.

One of the most frequent errors learners make with the word broadcast is treating it like a regular verb or adjective that follows standard suffix rules. Specifically, many people are tempted to add '-ed' to make it 'broadcasted.' While 'broadcasted' is increasingly accepted in some dictionaries as a past tense verb, it is almost never used as an adjective. You should always use 'broadcast' when modifying a noun. For example, 'a broadcast program' is correct, while 'a broadcasted program' sounds awkward and non-native. This is because 'broadcast' is an irregular word that functions as its own past participle and adjective form. Keeping it simple and using the base form will ensure your English sounds more natural and professional.

The '-ed' Trap
Incorrect: 'The broadcasted news was very depressing.'
Correct: 'The broadcast news was very depressing.'
Explanation: As an adjective, the form is always 'broadcast.'
Confusing with 'Streaming'
Incorrect: 'I watched a broadcast on Netflix.'
Correct: 'I watched a stream on Netflix.'
Explanation: 'Broadcast' specifically refers to over-the-air or traditional network distribution. Streaming is usually 'on-demand' or 'unicast,' which is the opposite of broadcast.
Misusing 'Broadcasting'
Incorrect: 'He works in the broadcasted industry.'
Correct: 'He works in the broadcast industry' or 'He works in broadcasting.'
Explanation: 'Broadcasting' is the noun for the activity; 'broadcast' is the adjective for the industry.

The broadcast signal (not 'broadcasted signal') was lost during the storm.

Another common mistake is failing to distinguish between 'broadcast' and 'narrowcast.' In the modern digital age, many communications are 'narrowcast,' meaning they are sent to a specific, targeted group of people. If you send an email to three friends, that is not a 'broadcast email.' A 'broadcast' must be intended for a wide, general audience. Using 'broadcast' to describe private or small-group communications can lead to confusion. Similarly, people often confuse 'broadcast' with 'televised.' While all televised programs are broadcasts, not all broadcasts are televised (they could be radio). If you want to be specific about the medium, use 'televised' or 'radio.' If you want to talk about the method of distribution generally, use 'broadcast.'

Is this a broadcast station or a cable-only channel?

In technical writing, there is a risk of confusing 'broadcast' with 'multicast.' In networking, a 'broadcast' goes to every single device on a network, whereas a 'multicast' goes to a specific group of interested devices. Using these terms interchangeably in an IT context is a significant error. Even in general English, 'broadcast' implies a lack of targeting—it is for whoever happens to be 'tuned in.' If you are talking about a highly targeted marketing campaign, 'broadcast' is the wrong adjective; you would likely want 'targeted' or 'personalized.' Understanding that 'broadcast' implies a 'shotgun approach' (hitting everything at once) will help you avoid using it in contexts where precision and targeting are the main features.

The broadcast range is limited by the height of the antenna.

Finally, avoid using 'broadcast' as an adjective to describe something that is merely 'popular' or 'well-known.' While a broadcast program might be popular, the word 'broadcast' only describes how it is delivered, not how many people like it. You wouldn't say 'that is a very broadcast song' to mean it's a hit. Instead, you would say 'that song has received a lot of broadcast airplay.' Here, the adjective 'broadcast' correctly modifies 'airplay' (the amount of time it is played on the radio), providing a clear and accurate description of the situation. Precision in these small details is what separates an intermediate learner from a truly fluent speaker.

The English language offers several synonyms for broadcast, but each carries a slightly different nuance depending on the medium and the intent of the communication. Understanding these differences is key to achieving a high level of precision in your speech and writing. While 'broadcast' is the most general term for one-to-many distribution, words like 'televised,' 'aired,' and 'transmitted' offer more specific alternatives. For example, 'televised' specifically implies the use of television, whereas 'broadcast' could also mean radio. 'Aired' is a more informal, common way to describe something being put on the airwaves, often used in phrases like 'the aired episode.' 'Transmitted' is a more technical term, focusing on the physics of the signal rather than the content of the program.

Televised vs. Broadcast
Televised: Specific to TV. 'The televised debate was seen by millions.'
Broadcast: Can be TV or radio. 'The broadcast debate was available on both FM and Channel 4.'
Transmitted vs. Broadcast
Transmitted: Focuses on the signal. 'The transmitted data was encrypted.'
Broadcast: Focuses on the public nature. 'The broadcast signal was intended for public consumption.'
Publicized vs. Broadcast
Publicized: Means making something known through any means (ads, posters). 'The event was well-publicized.'
Broadcast: Specifically means via radio/TV. 'The event was broadcast live.'

While the news was broadcast on the radio, it was also disseminated via social media.

In more academic or formal settings, you might encounter the word disseminated. This is a high-level synonym that means to spread information widely. However, 'disseminated' is much broader than 'broadcast'; you can disseminate information through books, word of mouth, or academic journals. 'Broadcast' remains tied to the specific technology of airwaves. Another interesting alternative is circulated. This is usually used for physical items like newspapers or rumors. You wouldn't say a TV show was 'circulated' unless you were talking about physical DVDs being passed around. Using 'broadcast' correctly shows that you understand the specific technological context of the communication.

The broadcast version of the film was edited for length and content.

When discussing the reach of something, you might use widespread. For example, 'there was widespread coverage of the election.' While 'widespread' describes the extent, 'broadcast' describes the method. You could have 'widespread broadcast coverage,' combining the two to show that many different stations were airing the news. In the digital world, we often use the word viral. A 'viral video' is distributed to many people, but it isn't a 'broadcast' in the traditional sense because it spreads from person to person (peer-to-peer) rather than from one central tower to everyone. Distinguishing between 'broadcast' and 'viral' is a great way to show you understand modern media dynamics.

The broadcast media landscape is changing rapidly due to the rise of internet-based alternatives.

Finally, consider the word published. This is the print equivalent of 'broadcast.' You publish a book, but you broadcast a radio show. In the age of the internet, these lines are blurring—some people say they 'published' a video to YouTube. However, in professional media, the distinction remains: 'broadcast' implies a live or scheduled transmission over airwaves, while 'published' implies making a static file available for people to access at their own convenience. By keeping these distinctions in mind, you can use 'broadcast' as an adjective with confidence, knowing exactly why it is the best word for the job.

常见错误
  • Using 'broadcasted' as an adjective. broadcast

    The word 'broadcast' is irregular. The adjective form is identical to the base form. 'Broadcast news' is correct; 'broadcasted news' is not.

  • Confusing 'broadcast' with 'streaming'. streaming (for internet video)

    Broadcast specifically refers to over-the-air radio or TV. If you are talking about Netflix or YouTube, use 'streaming' or 'online'.

  • Using 'broadcast' to describe a private message. private / direct

    Broadcast implies a wide, public audience. Sending a message to one person is not a broadcast.

  • Misplacing the stress on the second syllable. BROAD-cast

    The stress should always be on the first syllable. Pronouncing it as 'broad-CAST' sounds unnatural.

  • Using 'broadcasting' as an adjective for 'media'. broadcast media

    While 'broadcasting' is a noun, 'broadcast' is the standard adjective for the industry and its tools.

小贴士

Use the Base Form

Always use 'broadcast' as the adjective. Never add '-ed' or '-ing' when you are modifying a noun like 'media' or 'signal'.

Learn Collocations

Focus on common pairings like 'broadcast journalism' and 'broadcast rights.' These are the most natural ways to use the word.

Broadcast Quality

Use this phrase to describe high-quality work. It shows you understand professional industry standards.

Signal vs. Content

Remember that 'broadcast' can describe both the signal (the wave) and the content (the show). Use it clearly in both contexts.

Public Service

In many cultures, 'broadcast' implies a public service. Keep this in mind when discussing media policy or national news.

Be Specific

If you only mean television, use 'televised.' If you mean both radio and TV, use 'broadcast.' This precision improves your writing.

Emergency Alerts

Pay attention to 'broadcast alerts' on your phone. They are a real-world example of the adjective in action.

Stress the First Syllable

Make sure to say BROAD-cast. Putting the stress on the second syllable is a common mistake for learners.

Think of Seeds

If you forget the meaning, think of scattering seeds. It helps you remember the 'wide' and 'public' nature of the word.

Broadcast vs. Stream

Use 'broadcast' for live, over-the-air content and 'stream' for internet-based content to sound more like a native speaker.

记住它

记忆技巧

Think of a 'Broad' (wide) 'Cast' (throw). You are throwing information wide so everyone can catch it.

视觉联想

Imagine a giant tower throwing colorful seeds (information) over a huge city. Everyone who catches a seed hears a story.

挑战

Try to use 'broadcast' as an adjective in three different ways today: once about the news, once about a signal, and once about a professional standard.

词源

The word is a combination of 'broad' (meaning wide) and 'cast' (meaning to throw). It first appeared in the 18th century as an agricultural term.

原始含义: To scatter seeds by hand over a wide area rather than planting them in rows.

Germanic (Old English 'brād' + Old Norse 'kasta').

文化背景

Be aware that 'broadcast' is a neutral term, but 'broadcast standards' can be a sensitive topic involving censorship and free speech.

In the US, the FCC regulates broadcast airwaves, while in the UK, it is Ofcom. These bodies ensure broadcast standards are met.

The movie 'Broadcast News' (1987) explores the world of television journalism. The 'War of the Worlds' radio broadcast (1938) caused mass panic in the US. The 'Queen's Christmas Broadcast' is a long-standing tradition in the Commonwealth.
