好簡單的英文!!急呀

Do the children know what their teacher do after school?

_____DO____the children know what their teachers do after school?= 現在式

__DID_______the children know what their teachers do after school yesterday/ last week? 過去式 及有時間提示- 如 yesterday或 last week, last Monday 等

用 Do 或 Did 都可以, 例如 :1. 很多老師放学后都去進修。 Do the childrenknow what their teacher do after school? (日常談話)2. 上個月,英文老師日日冇精神,又經常講錯嘢。 Did the childrenknow what their teacher do after school? (一件以前發生的事)無論用 Do或Did, 動詞(main verb “know”) 永近遠是用 infinitive form.

ans:Do the children know what their teachers do after school?
因為個句子係用緊現在式
如果句子用過去式先要用did

答案應該是:
Do the children know what their teachers do after school?

Do
因為句子裏的 know 是 present tense,
所以是know
