Women who are exposed to second-hand some during their pregnancy_____be at risk of abortion.A.can B.must C.should D.need为什么选A
选A
句中some应该是smoke
先翻译:处于二手烟环境中的孕妇可能会有流产的危险.
这里can 表示理论上的可能.
情态动词表示可能性的辨析如下:
一、 接近100%的可能
这当然只有must才具有这么高的可能性,它的意思是“一定”“肯定”,所作出的推测几乎接近事实.如:
That hat must be Tom's.那帽子一定是汤姆的.
He must be coming by bus.他一定会乘公共汽车来.
二、 很有可能
表示可能性较大的情态动词主要有may,
should,ought to,它们大致相当于汉语的“可能”“应该”.如:
She should [ought to] be here soon.她应该很快就到.
We may be buying a new house.我们可能要买一座新房子.
三、 一般性的可能
在所有表示推测的情态动词中,might和could所表示的可能性最小,由于它们的语气较委婉,较不确定,所以往往相当于汉语的“可能”“也许”“说不定”等.如:
He might be waiting for you.他可能在等你.
She might not like the idea.她或许会不赞成这个想法.
We could all be millionaires one day.我们有一天可能都成为百万富翁.
四、 理论上的可能性
表示理论上的可能通常是用can,且可以用于肯定句中.如:
Food poisoning can cause death.食物中毒可导致死亡.
This kind of thing can happen every now and then.这种事情是随时可能发生的.
New England can be very warm in September.新英格兰有时9月份很热.
所谓理论上的可能性,就是指仅从理论上去考虑其可能性,至于实际情况如何,则不作考虑,比如说“食物中毒可导致死亡”,这只是理论上的一种推断,至于某人某次食物中毒了,他是否会死亡,则不在考虑之列——所以说,这种推测是非常“宏观”的!

这句话意思是 女性在怀孕期间接触二手一些在怀孕期间更容易流产
can 表示能,能够
must表示必须
should表示应该
need表示需要
这题考查的是情态动词意义的用法,根据意思 所以选a

must是必须 should是应该,按理应该 need是需要,都不和题意。can表猜测,说孕妇可能会有危险
