对
to, towards; for (good or bad for)
Structure
A 对 B + 形容词／动词
What it means
对 + a person or thing shows who or what is affected: 对我很好 “good to me”, 对身体不好 “bad for your health”, 对我说 “said to me”.
How it is built
A + 对 + B + adjective／verb: 看手机太多对眼睛不好 (Looking at your phone too much is bad for your eyes).
When to use it
Use it for how someone treats you (大家都对我很好, h2-1), what is good or bad for you, and who you speak to. This is not the 对 that means “right, correct” (对，是我).
Watch out
The 对 phrase comes before the adjective or verb, never after. ✗ 喝水好对身体。 ✓ 喝水对身体好。
Examples
老师对我们很好。
Our teacher is very good to us.
看手机太多对眼睛不好。
Looking at your phone too much is bad for your eyes.
