did的用法小結(通用多篇)

did的用法小結(通用多篇)

should 和ought to 篇一

should 和ought to 都爲“應該”的意思,可用於各種人稱。

---Ought he to go?

---Yes. I think he ought to.

表示要求,命令時,語氣由 should(應該)、had better最好)、must(必須)漸強。

助動詞do/does/did的用法 篇二

1、放在句首構成一般疑問句,例如:

Do you want to go there? 你想去那裏嗎?

Does he like English? 他喜歡英語嗎?

Did you see him yesterday? 你昨天看見他了嗎?

2、構成否定句do/does/did + not,例如:

I do not want to stay here 我不想呆在這裏。

He doesn’t like this book. 他不喜歡這本書。

Tom did not go to school yesterday. 湯姆昨天沒去上學。

3、句首加Don’t構成否定祈使句,例如:

Don’t go there. 不要去那裏。

Don’t be so silly. 不要這麼傻了。

注:此處只能用Don’t.

4、放在動詞原形前,加強該動詞的語氣,例如:

Do come to my family. 一定要來我家。

I did go there yesterday. 我昨天確實去那兒了。

I do miss you. 我確實想你。

5、用於倒裝句,例如:

Never did I hear of such a place. 我從未聽說過這樣一個地方。

Only when we come here do we know the beauty of the village.

只有當我們來到這裏才知道這個村莊的美。

注:引導此類倒裝句的副詞有never, seldom,rarely, little, only, so, well等。

6、可以用作代動詞,例如:

Do you like Shanghai? --你喜歡上海嗎?

Yes, I do. 是的,我喜歡。(do用作代動詞,代替like Shanghai.)

Does he like music? 他喜歡音樂嗎?

Yes, he does.是的,他喜歡。(does用作代動詞,代替likes music)

情態動詞+ have +過去分詞 篇三

1) may(might) have + done sth, can (could) have + done sth 表示過去,推測過去時間裏可能發生的事情。

Philip may (might) have been hurt seriously in the car accident.

Philip can (could) have been hurt seriously in the car accident.

2) must have +done sth,對過去時間裏可能發生的事情的推測,語氣較強,具有“肯定”,“諒必”的意思。

---Linda has gone to work, but her bicycle is still here.

---She must have gone by bus.

3) ought to have done sth, should have done sth

本應該做某事,而事實上並沒有做。否定句表示“不該做某事而做了”。

You ought to (should) have been more careful in this experiment.

He ought not to have thrown the old clothes away.(事實上已扔了。)

ought to 在語氣上比should 要強。

4) needn't have done sth 本沒必要做某事

I dressed very warmly for the trip, but I needn't have done so. The weather was hot.

5) would like to have done sth 本打算做某事

I would like to have read the article, but I was very busy then.

英語語法】did的用法 篇四

1、到底何時使用did?

did和其它助動詞一樣,本身無意義,自己不能獨立作謂語,只能和其它主要動詞一起構成謂語,用於構成一般過去時的否定句和疑問句,當然也常常用於代替上文中的行爲動詞的過去式。如:

I didn't go to school last Sunday. 上週日我沒上學。

Did you buy a new pen yesterday? 昨天你買了枝新鋼筆嗎?

2、did身後的動詞到底用什麼形式?

有的小朋友總不注意did身後的動詞用什麼形式,在否定句和疑問句中,

did身後的動詞必須用原形。 “他昨天沒有在家吃午飯。”

[誤] He didn't had lunch at home yesterday.

[正] He didn't have lunch at home yesterday.

3、我能用be動詞代替嗎?

不管怎麼說,含有行爲(實義)動詞的一般過去時的肯定句變成否定句或疑問句時,不能用be動詞,必須用到did!含be動詞的句子構成否定句或疑問句都絕不會讓did露面!

例句:They went to the park last week. (改爲否定句)

[誤] They weren't go to the park last week.

[正] They didn't go to the park last week.

may 和might 篇五

1、may的用法

(1)表示詢問或說明一件事可不可以做。

(2)表示一件事或許會發生或某種情況可能會存在,通常用在肯定句和否定句中。

注意:表示可能性時,can't語氣強,表示“不可能”,may not語氣弱,表示“可能不”。

2、might的用法

(1)表示詢問或允許,指的是過去時間。

(2)表示可能發生的事,可以指過去時間,也可以指現在時間,語氣更加不肯定,可能性比may小一些。

3、may與might的特殊用法

(1)“may+主語+動詞原形”表示祝願。

(2)“may/ might well+動詞原形”表示(完全)能,很可能。

(3)“may/ might as well+動詞原形”表示最好,滿可以,倒不如。

(4)may be 是“情態動詞+系動詞be”結構,表示“可能有,可能在”,否定式爲may not be。

maybe是一個詞,爲副詞,意爲“大概,或許,可能”,在句中作狀語。
