每个人都曾试图在平淡的学习、工作和生活中写一篇文章。写作是培养人的观察、联想、想象、思维和记忆的重要手段。写范文的时候需要注意什么呢？有哪些格式需要注意呢？这里我整理了一些优秀的范文，希望对大家有所帮助，下面我们就来了解一下吧。
did的用法例句篇一
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，对过去时间里可能发生的事情的推测，语气较强，具有"肯定"，"谅必"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
本应该做某事，而事实上并没有做。否定句表示"不该做某事而做了"。
you ought to (should) have been more careful in this experiment.
he ought not to have thrown the old clothes away.（事实上已扔了。）
ought to 在语气上比should 要强。
4) neednt have done sth 本没必要做某事
i dressed very warmly for the trip, but ineednt 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.
did的用法例句篇二
1、 到底何时使用did?
did和其它助动词一样，本身无意义，自己不能独立作谓语，只能和其它主要动词一起构成谓语，用于构成一般过去时的否定句和疑问句，当然也常常用于代替上文中的行为动词的过去式。如:
i didnt go to school last sunday. 上周日我没上学。
did you buy a new pen yesterday? 昨天你买了枝新钢笔吗？
2、 did身后的动词到底用什么形式？
有的小朋友总不注意did身后的动词用什么形式，在否定句和疑问句中，
did身后的动词必须用原形。 “他昨天没有在家吃午饭。”
[误] he didnt had lunch at home yesterday.
[正] he didnt have lunch at home yesterday.
3、 我能用be动词代替吗？
不管怎么说，含有行为（实义）动词的一般过去时的肯定句变成否定句或疑问句时，不能用be动词，必须用到did!含be动词的句子构成否定句或疑问句都绝不会让did露面！
例句：they went to the park last week. （改为否定句）
[误] they werent go to the park last week.
[正] they didnt go to the park last week.
did的用法例句篇三
1、放在句首构成一般疑问句，例如：
do you want to go there? 你想去那里吗？
does he like english? 他喜欢英语吗？
did you see him yesterday? 你昨天看见他了吗？
2、构成否定句do/does/did + not，例如：
i do not want to stay here 我不想呆在这里。
he doesn’t like this book. 他不喜欢这本书。
tom did not go to school yesterday. 汤姆昨天没去上学。
3、句首加don’t构成否定祈使句，例如：
don’t go there. 不要去那里。
don’t be so silly. 不要这么傻了。
注：此处只能用don’t.
4、放在动词原形前，加强该动词的语气，例如：
do come to my family. 一定要来我家。
i did go there yesterday. 我昨天确实去那儿了。
i do miss you. 我确实想你。
5、用于倒装句，例如：
never did i hear of such a place. 我从未听说过这样一个地方。
only when we come here do we know the beauty of the village.
只有当我们来到这里才知道这个村庄的美。
注：引导此类倒装句的副词有never, seldom,rarely, little, only, so, well等。
6、可以用作代动词，例如：
do you like shanghai? --你喜欢上海吗？
yes, i do. 是的，我喜欢。（do用作代动词，代替like shanghai.）
does he like music? 他喜欢音乐吗？
yes, he does.是的，他喜欢。(does用作代动词，代替likes music)
