2.can have done 的意思

e.g:You can have eaten it.
3.can be 能表示推测吗
不可以。表推测时,英语中只使用must,may,might,may not和can't。这五个表达的语气依次递减:
must:一定(语气肯定)
may:也许(不很肯定)
might:或许(比may语气更弱)
may not:也许不(表否定)
can't:一定不(must的反义)
推测现在的事情用must,may,might,may not和can't+do或be
e.g.She must be at home now.
The boy may play now.
推测过去的事情用must,may,might,may not和can't+have done
e.g.She might have been ill yesterday.
He must have hold the party.
注意:表推测的must,may,might,may not和can't是不可以与I think...连用。因为I think...已有推测的含义,故不能连用
4.would like to,should like to什么意思
would like to指想要做某事。同义词是want和feel like doing
至于should like to根本没有这种用法
5.By no means________misunderstand you
A.could we B.shall we
C.we shall D.we can
答案是A 为什么B不可以?
shall we表示的是疑问语气。这里是将状语提前,所以要倒装,将情态动词提前。实际上可以说成We could misunderstand you by no means.
6.I knew that if I wasn't able to avoid a mistake,chances were that no other doctor________,either.
A.should have been B.could have been
C.ought to have been D.must have been
答案是B 为什么??? 顺便解释下句子的意思.
这里could have been是在虚拟语气中使用的。有机会
意思是我知道假如我不能承受一个错误,其他医生都没有机会的。

一般都是 can be have done,
比如: it can be have finished early
3. 可以表示推测,但是一般都用it may be hers或者it could be right
4. 前者表达自己的意思和情愿,委婉方式的 例子见1, 后者那个,我没见过,现实中更没有
5. shall we用在疑问句,could we其实是we could, 表示我们能够
6. 我知道如果我不能避免一个错误,就也没有机会让别的医生看到了. could have,能够
neither,either
Neither的意思是“两个都不”(not either);either的意思是“两个中的任何一个”(one of two)或“两个中的各一个”(each of two)。
Neither常和nor用在一起;either常与or用在一起。
下面先看两个neither的例句:
Neither Mr.Li nor Mr.Zhang is in Hong Kong now.
李先生和张先生现在都不在香港。
I like neither of the novels.
这两本小说我都不喜欢。
在口语里,我们常用not either代替neither。如上面第二个句子,在口语中可以说:I don't like either of the novels.
下面是either的例句:
Either Mr.Li or Mr.Zhang is in Hong Kong now.
不是李先生就是张先生现在在香港。
We can take either road.
两条路我们可以任挑一条走。
在上面两句中,either表示one of two的意思。在下面的句子中,either作each of two和each of more than two things解:
They took seats on either side.
他们在两边就座。
Just above the platform,at either of the four corners is an exquisite female bust.
就在平台上,四个角落的每个角都有一个精致的妇女半身像。
在美国英语中,当either表示both和each的涵义时,它的动词用复数形式。例:
Either of them are enough to drive a man to distraction.
他们之中的任何一个都足以驱使一个人变得疯狂。
I do not think either of them are at home.
我认为他们两个人都不会在家。
请注意,当neither表示“亦不”涵义时,其后的主谓语往往要倒装。例:
You did not see her,neither did I.
你没有看见她,我亦未看见她。
You will not go to Macau,I neither will I.
你不想去澳门,我也不想去。
顺带一提,以上两句中的neither did I/neither will I 可说成nor did I/nor will I或and I didn't either/and I won't either.
