4.will表示习惯、请求,固有性质等。

情态动词用法口诀:
情态动词两特点,动词原形接后面,说话语气较委婉。
can"能力"may"许可",must"责任"或"义务"。
否定回答needn’t换,"需要"need,dare"敢"。
should"应该",would"愿",haveto"被迫"表客观。
can, could, may, might, must 皆可表示推测,其用法如下:
1)情态动词+动词原形,表示对现在或将来的情况的推测,此时动词通常为系动词。例如:
I don't know where she is,she may be in Wuhan.我不知道她在哪儿,可能在武汉。
2)情态动词+动词现在进行时,表示对现在或将来正在进行的情况进行推测。例如:
At this moment,our teacher must be correcting our exam papers.这时,想必我们老师正在批改试卷。
3)情态动词+动词完成时,表示对过去情况的推测。例如:
The road is wet.It must have rained last night.地是湿的,昨天晚上一定下雨了。
4)情态动词+动词的现在完成进行时,表示对过去正在发生事情的推测。例如:
Your mother must have been looking for you.你妈妈一定一直在找你。
5)推测的否定形式,疑问形式用can't,couldn't表示。例如:
Mike can't have found his car,for he came to work by bus this morning.
迈克一定还没有找回他的车,因为早上他是坐公共汽车来上班的。
注意:could,might表示推测时不表示时态,其推测的程度不如can,may。
考点名称:助动词
助动词:
协助主要动词构成谓语动词词组的词叫助动词,被协助的动词称作主要动词。
构成时态和语态:助动词是语法功能词,自身没有词义,不可单独使用,它没有对应的汉译,
例如:Hedoesn'tlikeEnglish.他不喜欢英语。(doesn't是助动词,无词义;like是主要动词,有词义)- 小学涉及到的助动词主要是do,以及它的两种时态:does和did。
例:Does he work in the factory? 他是在这个工厂工作吗?
Do you have a pen? 你有一支钢笔吗?
He didn’t go to school yesterday. 他昨天没有去上学。
助动词do 的用法:
1)构成一般疑问句,例如:
Do you want to pass the CET? 你想通过大学英语测试吗?
Did you study German? 你们学过德语吗?
2) do + not 构成否定句,例如:
I do not want to be criticized. 我不想挨批评。
He doesn't like to study. 他不想学习。
In the past, many students did not know the importance of English. 过去,好多学生不知道英语的重要性。
3)构成否定祈使句,例如:
Don't go there. 不要去那里。
Don't be so absent-minded. 不要这么心不在焉。
说明: 构成否定祈使句只用do,不用did和does。
4)放在动词原形前,加强该动词的语气,例如:
Do come to my birthday party. 一定来参加我的生日宴会。
I did go there. 我确实去那儿了。
I do miss you. 我确实想你。
5) 用于倒装句,例如:
Never did I hear of such a thing. 我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English.
只有在开始大学生活时我们才认识到英语的重要性。
说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
6)用作代动词,例如:
---- Do you like Beijing? --你喜欢北京吗?
---- Yes, I do. --是的,喜欢。(do用作代动词,代替like Beijing.)
He knows how to drive a car, doesn't he?
他知道如何开车,对吧? - 基本助动词:
be, do, have, 他们没有词汇意义,只有语法作用,如协助构成进行体,完成体,被动态,否定句,疑问句等。
例如 He is giving a lecture. 他在作报告
He has made a plan. 他已经订了计划
The small animals are kept in the cages. 小动物都关在笼子里。
助动词协助主要动词完成以下功用:
a. 表示时态,例如:
He is singing. 他在唱歌。
He has got married. 他已结婚。
b. 表示语态,例如:
He was sent to England. 他被派往英国。
c. 构成疑问句,例如:
Do you like college life? 你喜欢大学生活吗?
Did you study English before you came here? 你来这儿之前学过英语吗?
d. 与否定副词not合用,构成否定句,例如:
I don't like him. 我不喜欢他。
e. 加强语气,例如:
Do come to the party tomorrow evening. 明天晚上一定来参加晚会。
He did know that. 他的确知道那件事。
