在复合句中作主语的从句称为主语从句。通常位于主句谓语动词之前或由形式主语it代替,而真正作主语的主语从句置于句子末尾。 What she offers to her fans is honesty and happiness. 她给予粉丝的是真诚和幸福。 Before a problem can be solved,it must be obvious what the problem

若主句的主语为第一人称单数,谓语动词为think、consider、suppose、believe、expect、fancy、guess、imagine等,其后的宾语从句若表示否定意义,一般要把否定词转移到主句谓语动词前,从句谓语用肯定式。 I don’t think this dress fits you well. 我认为这条连衣裙不是很适合你。 考点3　表语从句 1.基本概念 在复合句中作表语的从句称为表语从句,通常位于连系动词后,有时用as if、because和why引导。 The most pleasant thing of the rainy season is that one can be entirely free from dust. 雨季最令人愉快的事情是人可以完全不受灰尘的袭扰。 I’d like to start my own business—that’s what I would do if I had the money. 我想自己创业——这就是如果我有钱,我想做的事情。 That’s why I think the trip along the Yangtze River will be a better choice. 那就是我认为长江之行将是一个更好的选择的原因。 2.常见句型 ①“This/That is

sounded as if somebody was knocking at the door. 听起来好像有人正在敲门。 The house was in such a mess—it looked as though a boom had dropped on it. 这个房子真乱,看起来就像被炸弹炸过一样。 考点4　同位语从句 1.基本概念 同位语从句用以说明其前面某一名词的具体内容。通常位于advice、demand、doubt、fact、hope、idea、information、message、news(消息)、order、problem、promise、question、request、suggestion、truth、wish、word(消息)等具有抽象意义的名词后面。 The news that our women volleyball team had won the championship encouraged us all greatly. 我们的女排赢得冠军的消息极大地鼓舞了我们所有人。 Jim kept his promise that he would always do everything he could for Mary to make sure of her happiness. 吉姆遵守了他的诺言,他将尽力为玛丽做一切事情来保证她的幸福。 2.that引导的同位语从句与定语从句的区别 同位语从句的引导词that 不充当从句的任何成分,即同位语从句本身是意义完整的陈述句,但that不可省略;定语从句的关系代词that 代替先行词,在定语从句中充当主语、宾语或表语,that可省略。 The rumor (that)he spread everywhere turned out to be untrue.(定语从句) 他到处散布的谣言最终证明是不真实的。 The rumor that Tom was a thief turned out to be untrue.(同位语从句) 关于汤姆是小偷的谣言最终证明是不真实的。 3.分隔式同位语从句 英语中,同位语从句一般是紧跟在其同位词的后面,但由于表达不同意义的需要,同位语从句可以被句子的其他成分隔开,这种从句就叫作分隔式同位语从句。 The notice came around two in the afternoon that the meeting would be postponed.(被谓语和状语分隔) 下午两点左右,有人通知说会议要推迟了。 We have no idea at all that he has gone.(被程度状语分隔) 我们一点儿都不知道他已经走了。 【点津】 在动词“insist(坚持)、order、command(命令)、suggest、advise、recommend(建议)、demand、require、request、ask(要求)”后的宾语从句和这些动词的过去分词后的主语从句,以及与这些动词相对应的名词所在的表语从句和同位语从句中,谓语部分常用“should+动词原形”的虚拟语气结构,其中should可以省略。 【强调】 1.引导词选择的口诀：缺什么填什么，什么不缺填that,是否填if/weather 2.同位语从句在考试中出现的概率很低。 3.动词前面的句子是主语从句，动词、介词和部分形容词后面的句子是宾语从句，系动词后面的句子是表语从句，名词后面的句子可能是同位语从句或者是定语从句。 小题快练　单句语法填空 ①Beijing will carry out measures to help bridge
