4. 由于that 引导的各种名词从句，都是陈述一个事实。所以，无论是主语从句还是宾语从句、表语从句、同位语从句，其主句中并没有“悬而未决，带有疑问”的意思。因此，宾语从句经常和say, think, wish, hope, expect, suppose, see, believe, agree, explain, order, command, suggest, propose, insist, demand, require, declare, announce, know, hear, feel, imagine, notice, prefer, find, report, find out, regret, remember, forget, learn, decide, discover等词连用。同位语从句经常和fact, news, hope, truth, idea, suggestion, thought, promise, order, story, problem, belief, word, message, information, proof, announcement, desire, answer, proposal, advice, condition等名词连用。

1. Who will attend the meeting has not been decided.

2. No one knows who will attend the meeting.

3. My question is who will attend the meeting.

4. The question who will attend the meeting remains to be discussed.

在本组句子中，每句都含有who will attend the meeting. 它在句1中作了句子的主语，是主语从句。在句2中作了knows的宾语，是宾语从句。在句3中作了is的表语，是表语从句。在句4中作了question的同位语，是同位语从句。

1. 英语中有一种wh-word，也叫特殊疑问词，因为这些引导词都含有wh两个字母。它们是 who, whom, whose, whoever, what, whatever, which, when, where, how, why, 这些词均可引导四种名词性从句，并且这些引导词仍然具有疑问的含义。

2. 主语从句可以用形式主语it替代，而把主语从句置于句子的最后。如：

It has not been decided who will take the place of the manager.

It is still a question when we shall have our sports meet.
