* 江苏省运河中学 冯海波 基本概念: 名词性从句是相当于名词的句子在句中作主语、宾语、表语、同位语, 因此分别称为主语从句、宾语从句、表语从句、同位语从句。 1、主语从句 (1) 引导主语从句的关联词有三类: 从属连词that(不充当句子成分,没有词汇意义) That they were in truth sisters was clear from the facial resemblance between them. 从属连词whether “是否”(不能使用if) Whether he will come here is not clear. 连接代词who, whom, whose, what, which, whoever whatever, whichever, whoever=anyone who whatever=anything that whichever=any…that) Examples: Who will give the speech is not known yet. Who the prize will be given to is not decided yet. Whose room it is is clear. What he said at the meeting was true. What he said at the meeting is not known yet. Which (one) you like has nothing to do with me. Whoever comes is welcome. Whatever I have is at your service. Whichever (of you) comes first will receive a prize. Whichever you want is yours. 连接副词where, when, how, why. Where the meeting will be held depends on the weather. When they are leaving is being discussed. How this happened is not clear to anyone. Why he was absent yesterday was that he was ill at home. (2) 主语从句常用it作形式主语的有 ① It +be +形容词 (obvious, true natural, surprising ,good , wonderful ,funny , possible , likely, certain ,probable, etc ) + that ---- It is probable that he told her everything . ②It + be +名词词组 (no wonder ,an honour, a good thing ,a pity, no surprise, etc ) + that --- It is no surprise that our team should have won the game . ③ It +be +过去分词(said ,reported ,thought ,expected , decided , announced ,arranged ,suggested ) + that --- .

It doesn’t matter ( makes no differences etc) + 连接代词或连接副词引导的主语从句 It makes no differences where we shall have the meeting . 当主语从句出现在感叹句中时, 用it 作形式主语.
