"你喜欢苹果吗？"写成 You like apples? 汉语这么说行，英语必须把动词提前。
一般疑问句就是能用 Yes / No 回答的问句，变法分三步。
句中有 be 动词：be 提前
- You are a student. → Are you a student?
- He is tall. → Is he tall?
- They are playing. → Are they playing?
句中有情态动词：情态动词提前
- You can swim. → Can you swim?
- I should go. → Should I go?
句中什么助动词都没有：借 do / does / did
- I like apples. → Do you like apples?
- She likes apples. → Does she like apples?
- They went home. → Did they go home?
注意：借了 do/does/did，后面动词打回原形：
- 错：Does she likes?
- 对：Does she like?
简短回答
- Do you like apples? — Yes, I do. / No, I don't.
- Is he tall? — Yes, he is. / No, he isn't.
回答里的助动词/be 动词不能省。
口诀：be 情态提前走，没助动词借 do/does/did；简短回答别丢尾，Yes 后 Yes 到底。
