解放军文职考试:用whether或if引导的宾语从句
用whether或if引导的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。此外,whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether,不用if:
①whether引导主语从句在句首时;
Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
Whether he can come to the party on time depends on the traffic.他能否准时参加派对得看交通情况。
②宾语从句放在句首表示强调时,只能用whether;
Whether this is true or not, I really don't know.这是否真实,我也不知道。
③引导表语从句,只能用whether;
The question is whether we can get in touch with her.问题是我们是否能联系上她。
④引导介词宾语时,只能用whether;
His father is worried about whether he lose his work.他的父亲担心他是否会失去工作。
I'm thinking about whether I should quit my present job.我正在考虑我是否应该辞去现 在的工作。
Everything depends on whether we have enough money.一切要看我们是否有足够的钱。
⑤if与whether都可以与or not连用,但后面紧跟着or not时只能用whether;
We didn't know whether or not she was ready.(此时只能用whether)
I wonder whether/if the news is true or not.(此时则二者都可以用)
⑥后接动词不定式时,用whether;
Can you tell me whether to go or to stay? 你能否告诉我是去还是留?
I can't decide whether to stay.我不能决定是否留下。
⑦用if会引起歧义时,只用whether;
Could you tell me if you know the answer ?
这句话有两种意思:“你能告诉我是否知道答案吗?”或“如果你知道答案,请告诉我,好吗?”。如用whether可避免歧义.
⑧whether可引导同位语从句,if不能引导同位语从句。
The question whether we should call in a specialist was answered by the family doctor.我们是否请专家由家庭医生来定。
