同位语从句是对与之同位的名词中心词作进一步解释, 能接同位语从句的常见名词有: idea, fact, news, belief, hope, evidence, opinion, problem, truth, answer, proposal, theory, decision, discovery, problem, thought, understanding等。e.g. The news that we won the game is
exciting.

back home.

whether the man is trustworthy.The fact that we talked about is very important. (定语从句)

(同位语从句) whether与if在名词性从句中的用法区别
if 一般只用于引导宾语从句,而whether可引导包括宾语从句在内的其他名词性从句。
连词whether引导主语从句、表语从句时不能用if来替换。e.g. Whether he will attend the meeting
is uncertain.
The question is whether he will come.
宾语从句中, whether常与or not搭配, 可以说whether or not, 而不说if or not。
e.g. I don’t care whether or not she will
attend the meeting.whether可用在介词后, 或带to不定式前, if则不可。
e.g. She doesn’t know whether to get
married now or wait.
I haven’t settled the question of
whether I’ll go back home.某些动词后面 (如discuss) 只能用whether, 不用if。
e.g. We discussed whether we should go
on climbing. Rewrite the following sentences
