我们不是在调查“他是否值得信赖”这个问题。(whether不可换成if)
（5）I made a promise that if anyone set me free I would make him very rich.
我曾许诺,如果谁我自由,我就让他非常富有。
有时同位语从句可以不紧跟在它所说明的名词后,而被别的词语隔开；
例句：

left the door open when she left home.
她突然起她可能在离开家时没把门关上。
(2) Word came that he had been abroad.
据说他已经出国了
doubt 在否定句中带同位语从句时的引导词通常是that; 在肯定句中则一般用 whether；
例句：
（1）There is some doubt whether he will come on time.
人们怀疑他是否会准时来。（2）I have no doubt that he will finish it on time.
我绝对相信他会按时完成任务的。
