在复合句中用作主语的从句叫主语从句，它是名词性从句之一。引导主语从句的有连词that和whether，连接代词who、what、which等，连接副词when、where、how、why等。 类别 例词 说明 从属连词 that，whether 两者在从句中均不作成分，只起连接作用：that无实义；whether表示“是否” 连接代词 who，what，which，whoever，whatever等 在从句中作主语、宾语等 连接副词 when，where，how，why等 在从句中作状语 探究点1　主语从句的引导词 1．从属连词that和whether：在从句中不作成分。 (1)that 本身无实义，在从句中不作成分，只起连接作用，但不可省略。 That he should return home safe and sound is a great wonder. 他竟然能安然无恙地回家，真是一大奇迹。 That they were in truth sisters was clear from the facial similarity between them. 从她俩的面貌相似度就能明显地看出她们是亲姐妹。 (2)whether引导主语从句时，可以单独使用，也可以和or或or not连用，意为“是否”。 Whether the plan will be carried out is still unknown. 这个计划是否会实施还不知道。 Whether it will do us good or harm remains to be seen. 此事对我们有利还是有害，还有待观察。 2．连接代词what、who、whom、whose、which、whatever、whichever、whoever等在从句中作主语、宾语等。 Whatever was said here must be kept secret. 这里说的话都应当保密。 Whoever makes mistakes must correct them. 凡是犯了错误的人都必须改正错误。 Whom we must serve is a question of vital importance. 我们必须为谁服务是一个极为重要的问题。 Which book you should read first is not important. 你应该先读哪本书不重要。 A typical Chinese wedding nowadays goes like this：when a new couple is engaged，what follows is a choice of the date for their marriage. 如今典型的中国式婚礼是这样的：当一对新人订婚后，接下来要做的事是选择结婚日期。 3．连接副词when、where、why、how、whenever等在从句中作状语。 When we arrive doesn't matter. 我们什么时候到没有关系。 Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。 Where we shall do the test is still under discussion. 我们将在哪里做测试还在讨论中。 探究点2　用it作形式主语的主语从句 主语从句一般放在句首，但有时为了避免主语过长， 可以用it 作为句子的形式主语，把主语从句移到句子的末尾。常见的句型有： 句型 说明 It＋系动词＋形容词＋that从句． 常用于此句型的形容词有important、(un)likely、possible、necessary、natural、wrong、uncertain等 It＋系动词＋名词(短语)＋that从句． 常用于此句型的名词(短语)有fact、idea、honour、question、pity、no wonder、no surprise等 It＋系动词＋过去分词＋that从句． 常用于此句型的过去分词有known、proved、said、decided、suggested、thought、reported、believed等 It＋特殊动词＋that从句． 常用于此句型的动词有appear、happen、seem、occur等 It is important that students know how the Internet can be used. 重要的是学生要知道如何使用互联网。 It is no wonder that you've achieved such a great success. 难怪你取得了这么大的成功。 It is reported that a violent earthquake happened in Japan two weeks ago. 据报道，两周前日本发生了强烈地震。 It happened that they were out that day. 碰巧那天他们不在家。 It suddenly occurred to me that I had left my purse at home. 我突然想起来我把我的钱包落在家里了。 1．主语从句应用陈述语序。 Whether he will be in time for the meeting is doubtful. 他能否赶上会议还很难说。 2．and连接两个或两个以上的主语从句作主语时， 谓语动词用复数；由两个或两个以上连接词引导一个主语从句时，谓语动词用单数。 When and where the meeting will be held has not been decided yet. 会议将在何时何地举行还没定下来。 When they will set off and where they will go have not been decided yet. 他们何时动身，要去哪里，还没定下来。 3．在“It be＋过去分词＋that从句”中，当过去分词是suggested、advised、ordered、 required、requested、insisted等表示建议、命令、要求等意义的词时， that从句应使用虚拟语气， 即谓语动词用“(should＋)动词原形”。 It is suggested that the work (should) be done with great care. 有人建议， 这项工作得特别谨慎地去做。 4．whether的特殊用法 whether引导的主语从句， 如果用it作形式主语，引导词whether可以换成if。 It has not been decided yet whether/if he will cut down his novel.＝Whether he will cut down his novel has not been decided yet. 他是否删减自己的小说还没决定。 Ⅰ.单句语法填空 1．__Whose__
