两个含情态动词的句子,有情态动词的句子是什么句型?

情态动词和后面的动词一起构成谓语,所以含有情态动词的句子属于普通的句型,如是Ican'tswim.

1、CanIhave some fish please?

2、The girl can’t swim, but she can skate.

3、Don’t talk in class, you should listen to the teacher carefully.

4、l would not choose this color.

5、You must finish your homework before playing with the dog.

l need time to exercise regularly as can not walk fast easily.I could play

basketball whenIwas at school.Bu

now l may not have the energy to

run for catching the bus foravoiding work late.So lthink l mustsqueeze enough time to take part insports activities to build up a goodbody .Ibelieve lwill be whatlusedto be,healthy and strong

情态动词用在行为动词前,用来表示能力、允许、许诺、可能、必须、劝告、意愿等概念和态度。常见的情态动词有: can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would)。

例如:

Can you sing English songs? 你会唱英语歌吗?

Shall we begin now?我们现在就开始吗?

You must obey the school rules.你必须遵守校规。

You can’t smoke here.你不能在这里吸烟。

He had to leave.他不得不离开。

Let us go,will you?让我们去吧,行吗?

主语+情态动词can/may/must/should+动词原形+其他。

情态动词后不能加宾语,只能加动词原形一起做谓语。谓语的后面可以接宾语的,看例句:

You shoule help your brother with hisChinese.这个句子中your brother就是动词can help 的宾语。另外,情态动词没有人称的变换形式。

l can speak English.

He could play the piano when he was five years old.

例句:I can do it.

He should accept it.

We must always wear safety belts when we drive a car, we must never drink wine before we drive a car.

我们开车必须系安全带,我们开车前必须不能喝酒。

We should always respect the old and help the young

我们应该总是尊重老人帮助小孩(尊老爱幼)

情态动词一般放在主语之后,谓语动词之前。比如经典例子:I can not teach you swim,my younger brother is a better teacher than I.我不会教你游泳,我弟弟比我教的好。

上个句子用了情态动词can,表示能。频度副词可以放在主语后,谓语动词前,比如:I often go to the library.我经常去图书馆。句中用了频度副词often,表示经常,常常。

Your homework could be finished last night,You could finish your homework last night,你晚上能够完成你的作业

You could clean the classroom with your friend.

Must表示必须它是一个情态动词在句中有很多用法,比如表示命令你必须5:00起床,you must get up at 5 o'clock every morning。

Master也表示猜测一定肯定,比如这本书肯定是李雷的,因为上面有他的名字,this book must be released because there's his name on the book.

Must作为情态动词,后面必须加一个动词原形,一起构成谓语,例如I lost my dictionary,I must find it,我丢了我的词典,我必须找到他,句子中的must find属于合成谓语,再比如Must I finish my homework today?Yes you must,No you need it,我今天必须完成我的作业吗?

是的,你必须完成,不,你不必
