10、hat （whatever, whoever）等代词引导的主语从句。What they are after is money.他们追求的是金钱。Whatever was said here must be kept secret.这里说的话都应当保密。二、由连词that引导的主语从句。其中that 一般不可省略，但若用it作形式主语，that 从句后置时，则可省略。为避免头重脚轻，我们倾向用it开头，后接be, seem等。如果 句子是疑问形式，就只能用带it的结构。That money doesnt grow on trees should be obvious.金钱不能从树上长出来是显而易

11、见的。It is obvious （that） money doesnt grow on trees .显而易见，金钱是不能从树上长出来的。Has it been announced when the planes are to take off?飞.机什么时候起飞宣布 了没有?注意：1）选用what还是用that引导主语从句要根据关联词在从句中是否担任成分而定。且what （以及whatever, whoever等）引导的主语从句一般不用it作形式主语。What he said is true他说的是真的。（what在其引导的主语从句中作宾语。）That China is a great s

12、ocialist country is well known. （=ltzs well known that.）众所周知,中国 是一个伟大的社会主义国家。（that在其引导的主语从句中不作任何成分，.也无词义，只 起连接作用。）2） it引导的强调句与it作形式主语的复合句不可混淆。it引导的强调句是用来对句中某一 成分加以强调，其结构为：It is （或was） +强调部分+that （或who） .”强调句去掉It is （或 was） .that （或who）框架后，剩余部分为一个完整的句子。It was I that（who） met Mary in the street yester

13、day.是我昨天在街上遇见了玛丽。（强调主语） 3）常见的用it作形式主语的复合句结构：* lt is+形容词（necessary, strange, important, wonderful, possible* likely,等）+that 从 句，从句中常用虚拟语气。Its necessary that he write something in English.他用英语写点东西是必要的。Its strange that she did not go to school yesterday.奇怪的是她昨天没去上学。* ltis+名词（a fact, a pity , no wonder,

14、 good news,等）+that 从句Its a pity that she should have said so.真遗憾她竟然会这么说。* lt is+过去4）词,（said, reported, decided, unknown 等）+that 从句Its said that our English teacher will go abroad next week.据说我们英语老师下周要去出国。* lt+不及物动词（seems, appears, happens, matters 等）+that 从句It seems that she is in great need of help

15、.看来她急帮忙。4）主语为从句时，一般要用单数谓语动词形式；但如果引导的从句作主语、代表复数概念 （常可从表语上看出）时，谓语动词则常用复数形式：What we need is water.我们需要的是水。What we needr are useful books.我们需要的是有用的书。三、由连接代词或连接副词（或if, whether）引导的主语从句。When they will come hasnt been made public.他们什么时候回来还没有宣布。Whether lzll attend the meeting hasnt been decided.=lt hasnt bee

16、n decided whether（if） I/ll attend the meeting.我是否参加会议还未决定。Step4.
