he must have finished his homework

He must have finished his homework,hasn't he 或 didn't he?

用法請參考下面資料:

陳述句含有情態動詞must有兩種情況：

1、must表示“必須”,反意疑問句部分為mustn’t…?/ needn’t…?

He must study hard at English,mustn’t he?/ needn’t he?

You must go home now,needn’t you?/ mustn’t you?

We mustn’t be late,must we

2、must表示推測：“一定,肯定” 反意疑問句部分與must后面的動詞呼應

You must be joking,aren’t you?

He must be ill,isn’t he

3、注意：用must對過去的動作推測時,反意疑問句部分的助動詞用did或have,而對過去的狀態推測,反意疑問句部分的be動詞用was:

She must have finished her work,hasn’t she / didn’t she

Jack must have arrived here yesterday,didn’t he

He must have been a policeman,wasn’t he

He has finished his homework 這個句子對嗎

從句法上來說，這個句子是正確的，不過finish是暫時性動詞，后面不能加時間的短語，比如for或者since引導的句子，而這個句子后面無時間性短語，所以是正確的

他做他的作業是He does his homework還是He do his homework

He does his homework是對的，因為he是三單，動詞要變復數：而He do his homework是一個錯誤的句子。

現在時：He does his homework

過去式：He did his homework

將來時：He will/is going to do his homework

heisdoinghishomework是什么意思

he is doing his homework

他正在做家庭作業
