在英语中，引导同位语从句的词通常有连词(that, who, whether)，连接副词(how, when, where)等。

例如：They were all very much worried over the fact that you were sick.对你生病这件事，他们都很焦虑。The question who should do the work requires consideration.谁该做这项工作，这个问题需要考虑。We haven't yet settled the question where we are going to spend our summer vacation.我们还没有决定到什么地方去度暑假。注：在名词doubt“怀疑”后的同位语从句用whether连接；在no doubt“不怀疑”之后的同位语从句用that连接。例如：We have some doubt whether they can complete the task on time.我们怀疑他们是否能准时完成任务。There is no doubt that Zhang Wei will keep his promise.我们相信张伟会守信的。同位语从句：that有些名词的后面可以接that引导的同位语从句：We came to the decision that we must act at once.我们做出决定：我们必须立即行动。He made a proposal that the meeting be postpone.他提议会议延期。There was little hope that he would survive.他幸存的希望很小。
