有害
When something is harmful or detrimental, you can describe it using 有害 (yǒu hài).
This word is often used to talk about things that are bad for your health or the environment. For example, smoking is 有害 for your lungs.
It can also be used for actions or situations that have a negative impact. Think of it as meaning "has harm."
When we say something is harmful or detrimental in Chinese, we often use the adjective 有害 (yǒu hài). This word is straightforward and widely applicable in various contexts. It's frequently followed by an object to specify what it is harmful to, for example, 有害健康 (yǒu hài jiàn kāng - harmful to health) or 有害环境 (yǒu hài huán jìng - harmful to the environment).
You'll often see 有害 used in warnings or advisories, like on product labels or public health campaigns. It's a key term to understand for expressing potential dangers or negative impacts in everyday conversation and formal discussions alike. Remember, when you want to communicate that something is bad for something else, 有害 is an excellent choice.

§ Mistakes people make with 有害
Many learners, especially at the A2 level, make a few common mistakes when using 有害. Let's look at them so you can avoid them.
§ Mistake 1: Confusing 有害 with 坏 (huài) or 糟糕 (zāogāo)
While all three can convey negativity, they are not interchangeable. 有害 specifically means 'harmful' or 'detrimental,' implying damage or negative consequences. 坏 generally means 'bad' or 'broken,' and 糟糕 means 'terrible' or 'awful.' You wouldn't say something is 'bad for your health' using 坏 in the same way you'd use 有害.
- DEFINITION
- 坏 (huài): bad; broken; spoilt
- DEFINITION
- 糟糕 (zāogāo): terrible; awful; bad luck
For example, you can say food is 坏 (huài) if it's gone bad, but if it's bad for your health, you use 有害.
这个食物坏了，不能吃了。(This food has gone bad, cannot eat it.)
过度饮酒对健康有害。(Excessive drinking is harmful to health.)
§ Mistake 2: Incorrectly using 有害 without a clear object or context
有害 often needs a clear indication of *what* it is harmful to. While sometimes it can be implied, it's generally better to be explicit. Just saying 'It is harmful' without context might sound a bit incomplete in Chinese, especially in more formal or informative settings.
Instead of:
它是有害。(It is harmful.)
Try to specify what it's harmful to:
这种化学物质对环境有害。(This chemical substance is harmful to the environment.)
§ Mistake 3: Overusing 有害 in situations where simpler expressions suffice
Sometimes, learners default to 有害 when a simpler adjective or phrase would be more natural. For instance, if something is just 'not good' or 'bad for you' in a general sense, you might use 对...不好 (duì...bù hǎo) or 不利 (bù lì) instead.
- DEFINITION
- 对...不好 (duì...bù hǎo): not good for...
- DEFINITION
- 不利 (bù lì): unfavorable; detrimental
For example, if you want to say 'staying up late is not good for your health,' you could say:
熬夜对身体不好。(Staying up late is not good for your body.)
While '熬夜对身体有害' is not incorrect, '对身体不好' is often a more common and natural phrasing for general negative effects that aren't necessarily 'harmful' in a strong sense.
这个决定对公司发展很不利。(This decision is very unfavorable for the company's development.)
By keeping these points in mind, you can use 有害 more accurately and naturally in your Chinese conversations and writing. Keep practicing, and you'll get it right!

Comment l'utiliser
有害 (yǒu hài) is an adjective that means "harmful" or "detrimental." It's often used to describe things that have a negative impact on health, the environment, or a situation. It can be used directly before a noun or as a predicate.
Examples:
- 吸烟对健康有害。(Xīyān duì jiànkāng yǒuhài.) - Smoking is harmful to health.
- 这种化学物质是有害的。(Zhè zhǒng huàxué wùzhì shì yǒuhài de.) - This chemical substance is harmful.
- 过度使用手机对眼睛有害。(Guòdù shǐyòng shǒujī duì yǎnjīng yǒuhài.) - Excessive use of mobile phones is harmful to the eyes.
A common mistake is to confuse 有害 (yǒuhài) with 伤害 (shānghài). While both relate to harm, 有害 is an adjective describing something as harmful, whereas 伤害 is typically a verb meaning "to harm" or "to injure," or a noun meaning "harm" or "injury."
Incorrect: 这种食物伤害你的健康。(Zhè zhǒng shíwù shānghài nǐ de jiànkāng.)
Correct: 这种食物对你的健康有害。(Zhè zhǒng shíwù duì nǐ de jiànkāng yǒuhài.) - This food is harmful to your health.
Another mistake is to use 有害 as a verb. Remember it's an adjective.
Incorrect: 这个行为有害了环境。(Zhège xíngwéi yǒuhài le huánjìng.)
Correct: 这个行为对环境是有害的。(Zhège xíngwéi duì huánjìng shì yǒuhài de.) - This behavior is harmful to the environment.

Opposite of 有害
The opposite of 有害 is 无害 (wúhài), which means 'harmless'. 无 (wú) means 'without'.
