Grammar Rule in 30 Seconds
Use 'Today', 'Tomorrow', and 'Yesterday' to anchor your sentences to the present, future, or past without needing specific dates.
- Use 'Today' for the current 24-hour period: 'Today is sunny.'
- Use 'Tomorrow' for the day after now: 'Tomorrow is Tuesday.'
- Use 'Yesterday' for the day before now: 'Yesterday was cold.'
Overview
yesterday看了一部很棒的电影，但你的意思是tomorrow才去。这种事常有！这三个小词——today（今天）、tomorrow（明天）和yesterday（昨天）——是你在英语中理解时间的绝对好朋友。它们是谈论你的计划、分享故事以及仅仅是组织生活的基础。把这些词用对，你就已经在听起来更自然的道路上了。它们看起来很简单，但掌握它们是巨大的一步。让我们确保你再也不会意外地把Zoom面试安排在错误的一天。today、tomorrow和yesterday是时间副词。这只是一个花哨的说法，意思是它们告诉你某事*何时*发生。可以把它们想象成日历上简单的时间标记。Yesterday是今天的前一天。Today是你现在所处的这个24小时的时间段。而tomorrow是即将到来的那一天。它们是英语中最常见的词汇之一，从给朋友发短信（coffee tomorrow?）到填写官方表格，无处不在。它们是你区分过去、现在和未来的第一个也是最重要的工具。与许多语法不同，你不需要为这些词记忆复杂的词尾或动词变化。真正的诀窍是像搭配完美的鞋子和衣服一样，将它们与正确的动词时态相匹配。How This Grammar Works
today就是星期一，yesterday是星期天，tomorrow是星期二。如果你在星期五读，那么today是星期五，yesterday是星期四，tomorrow是星期六。它们是“现在”的锚点。Yesterday指向过去。所以，你必须使用过去时的动词。例如：I *walked* to the store yesterday.Today指向当天。你可以使用现在时（I *am* busy today）、针对当天早些时候发生的事情使用过去时（I *ate* breakfast today），或针对当天晚些时候将要发生的事情使用将来时（I *will call* you today）。它是一个相当灵活的超级明星。Tomorrow指向未来。所以，你必须使用将来时的动词。例如：We *will watch* a movie tomorrow.或We *are going to watch* a movie tomorrow.
Formation Pattern
today、tomorrow或yesterday这些词。没有复数形式，没有特殊的词尾。它们非常简单。唯一的“模式”是你在句子中放置它们的位置。
Yesterday, I played video games.
Today, I have a lot of homework.
Tomorrow, she is visiting her family.
I played video games yesterday.
I have a lot of homework today.
She is visiting her family tomorrow.
I played yesterday video games听起来非常奇怪。坚持放在句首或句末。这就像穿袜子。它们可以在鞋子之前穿，或者你可以拿着它们……但你不能在穿上鞋子*之后*再穿它们。那根本行不通。
When To Use It
- 制定计划： 当你组织社交生活时，这些词是必不可少的。
Are you free tomorrow?或Let's get lunch today.你会在WhatsApp、iMessage或任何你用来和朋友聊天的应用中不断使用它们。 - 讲故事： 当你叙述一个事件时，
yesterday是你的英雄。You won't believe what happened yesterday. I saw a celebrity at the coffee shop! - 提供更新： 在工作或学校的语境中，它们能提供清晰度。
I finished the report yesterday.或The presentation is tomorrow morning. - 设置提醒： 为自己或他人设置。
Remember, we have that appointment tomorrow. - 在社交媒体上：
Yesterday's sunset was amazing! #nofilter或Big project launching tomorrow! Stay tuned.

Contrast With Similar Patterns
Today、tomorrow和yesterday非常具体。如果你想表达得更笼统呢？或者用日期更具体地表达？那就是这些其他模式发挥作用的时候了。Today/Tomorrow/Yesterday vs. 星期几Today:I'm going to the gym today.(特指*今天*)On Monday:I go to the gym on Mondays.(一个普遍的习惯。意思是每个星期一。) 或I will see you on Monday.(一个特定的未来星期一)。
Yesterday vs. The Day BeforeYesterday:She left yesterday.(今天的前一天。)The day before: 这用于谈论*过去*某个特定时间点的前一天。更常用于讲故事。I met her on Tuesday. The day before, I had been really nervous.在这里，the day before指的是星期一。这更高级。
Tomorrow vs. The Next DayTomorrow:The package will arrive tomorrow.(今天的后一天。)The next day: 和the day before一样，这用于讲述过去的故事。We finished the project on Friday. The next day, we celebrated.在这里，the next day指的是星期六。这是对未来事件的过去视角。
today、tomorrow和yesterday看作是你即时的、个人的时间线。星期几、the day before和the next day用于更复杂或重复的时间线。Quick FAQ
todays或tomorrows吗？today、tomorrow、yesterday。这是英语少数几次决定保持简单的时候。让我们享受它吧。tomorrow morning却不说today morning？Today与this搭配变成this morning。Yesterday也使用自己的名字（yesterday morning）。但是yesterday的晚上是特殊的（last night），today的晚上也是特殊的（tonight）。Tomorrow是最一致的：tomorrow morning、tomorrow afternoon、tomorrow night。I will go tomorrow和I am going tomorrow有什么区别？I will go tomorrow是一个简单的事实陈述或在那一刻做出的决定。I am going tomorrow（使用现在进行时表示将来）通常意味着这是一个固定的计划或安排。例如，你已经有票了。在A0级别，你几乎可以互换使用它们。today谈论过去吗？I had a big lunch today. 午餐发生在过去，但仍然在同一个日历日。Verb Agreement with Time Words

文化笔记
In US/UK business culture, 'tomorrow' is a strict deadline. If someone says 'by tomorrow,' they usually mean by 9:00 AM the next day.
The concept of 'Mañana' (tomorrow) can sometimes be more fluid in certain cultures, meaning 'in the future' rather than 'the literal next day'. In English, 'tomorrow' is almost always literal.
The phrase 'That is so yesterday' is a common idiom meaning something is out of style or no longer cool.
From Old English 'to dæge' (today), 'to morgenne' (tomorrow), and 'geostran dæg' (yesterday).

常见问题 (8)
It is better to say `last night`. While people will understand you, `last night` is the standard expression.
It can be both! In 'Tomorrow is Monday,' it is a noun. In 'I will go tomorrow,' it is an adverb.
Yes, it is common to put a comma after a time word at the beginning: `Yesterday, I went to the store.`
Yes, in a general sense, it can mean 'nowadays' or 'in this era'. Example: `Today, technology is everywhere.`
In English, relative time words like `today`, `tomorrow`, and `yesterday` act as adverbs that already include the 'on' meaning within them.
There isn't a single common word like 'tomorrow'. We just say `the day after tomorrow`.
We say `the day before yesterday`. Some old books use 'ereyesterday,' but no one says that now!
No. `Tomorrow` is for the future. You must use a future verb like 'will' or 'is going to'.
