虚拟语气 would 与 could 区别
1在请求时,没区别
如 Could you go with me? =Would you go with me?
2在表示习性时,不用could ,用 would
Ipushed the door, but it wouldn't open.
我用力推门却推不开.
3could用在wish的句型中:
I wish I could go to the Moon.
4 would ,could 都可以用在带if条件句的虚拟语气主句中,意思大致不变.
If I had a lot of money, I would/could buy a set of house in Beijing.
5 表示推测时,不用would
She could have gone to the cinema .(她可能看电影去了)
could与would的区别 请求时该用would 还是could
情态动词could的用法
could的否定形式是could not,多缩写为couldn't,两者通常都读作[>kudnt]。
(1)表示能力,意思是:能,会。
【例】
Could you speak English then? 那时你能讲英语吗?
He said he couldn't follow me. 他说他跟不上我。
注意:①could(能)和was/were able to 都表示过去一般具有某种能力。
【例】
He could (was able to) swim very well when he was nine. 他九岁时就很会游泳。
②was (were) able to 可以表示过去某时有某种具体的能力并且实际上可以做到,但could表示过去的习惯能力。
【例】
Although the driver was badly hurt, he was able to explain what had happened. 司机虽受重伤,但仍能说明发生了什么事。
(2)表示可能性,意思是:可能。
【例】
That big cinema can seats 2,000 people. 那家大电影院能坐2,000人。
He said he couldn't come. 他说他不能来。
(3)提出请求、疑问或看法(could是虚拟语气,代替can,在时间上与can没有区别,只是语气比can委婉。can语气直爽、肯定)。
【例】
----Could you let me have your passport?
----Yes, here it is.
—看看你的护照好吗?
—行,这就是。
(4)表示惊异、不信等情绪(用于疑问和否定句中,此时could与can用法相同,无时间上的差别,用could语气缓和,情绪要弱)。
【例】
Who could have taken them? 谁会把它们拿走了呢?
She couldn't have left so soon. 她不可能这么快就走了。
(5)表示与事实相反的情况(用于虚拟语气)。
【例】
How I wish I could go with you!
怎么用would和could啊?它们的区别在哪里啊?
情态动词could的用法:
1、表示能力,意思是:能,会。
例子:Could you speak English then? 那时你能讲英语吗?
注意:could(能)和was/were able to 都表示过去一般具有某种能力。
2、表示可能性,意思是:可能。
例子:He said he couldn't come. 他说他不能来。
3、提出请求、疑问或看法
例子:Could you let me have your passport? 你能让我用你的护照吗?
4、could是虚拟语气,代替can,在时间上与can没有区别,只是语气比can委婉。can语气直爽、肯定。
例子:How I wish I could go with you! 我多么希望和你们一道去!
5、表示惊异、不信等情绪
例子:She couldn't have left so soon. 她不可能这么快就走了。
情态动词would的用法:
1、用在疑问句中,表示委婉,客气的表达,以代替比较生硬的will
例子:Would you please ive me a hand? 您能帮我一个忙吗?
2、用在过去将来时态中,后面跟动词原形
例子:Tom told us he would come over the next day. 汤姆告诉我们,他第二天会过来。
3、用在固定搭配短语中
would like to do sth 想要做某事
例子:They【 would like to 】lend us a hand.
could和would的区别:
1、可能性差别:
could do和would do的区别在于could do 是讲能不能做到(做事情的能力)
would do 是说会不会去做,想不想(愿意不愿意)
一个是有没有可能性,一个是有可能性但是更有选择
2、语气差别:
could和would都可用于虚拟语气,它们之间只有细微的语气差别。比如could有猜测之意。

当句子里有you'd 时,怎么判断是would should could ?
通常should和could不缩写 遇到 you’d的时候多为would 有时候也可能是had 比如You’d bettet have a short break. 在这里就是had的缩写 had better do 最好做某事 would like to do
