1、Section Grammar&Writing写作专题突破Unit 1语法专题突破Section 语法专题突破主语从句一、定义主语从句是在复合句中充当主语的从句，通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。二、引导主语从句的连接词有三类1连词：that，whetherThat he will attend the meeting has excited everyone of us.他要来参加会议使我们每一个人都十分激动。Whether the work can be completed on time is doubtful.这项工作能否按时完成还不一定呢。2连接代词：
2、who，whom，whose，what，which，whoever，whatever，whichever等。Who killed the scientist remains a question.谁杀死了那位科学家，仍然是个问题。What he wanted to see was an end to all the armies of the world.他所想看到的是世界上所有军队全部消亡。3连接副词：when，where，why，how连接副词在从句中充当状语，不能省略。Why he didnt come here is not clear to everyone.他为什么没来谁也不清楚。
3、When the broadcast station will be ready is unknown.广播站将于何时竣工目前还不知道。Where we will go hasnt been decided.我们要去哪儿还没定下来。三、用it作形式主语的主语从句1可以用it作形式主语的主语从句如果主语从句太长，为避免句子结构头重脚轻，我们可用it作形式主语，而把主语从句放在主句谓语部分之后，尤其是当主句的谓语动词是连系动词时。It is a pity that you didnt go to see the film with me yesterday.很遗憾你昨天没有和我去看电影。It is
4、 almost certain that their government will lose the next election.他们的政府在下次选举中将失利，这几乎是肯定的。It hasnt been decided whether the meeting will be held tomorrow.明天是否要开这个会还没定下来。【特别提醒】连接代词what，whoever，whatever，whichever等引导的主语从句不宜用it作形式主语。What is worth doing is worth doing well.凡是值得做的事就值得把它做好。Whatever was said
5、 here has left us much to think.这里所说的一切都让我们深思。Whoever comes will be welcome.谁来都欢迎。2必须用it作形式主语的主语从句在某些特定结构中，我们一般不将主语从句位于句首，而需用it作形式主语，把主语从句后置。(1)It is said/reported.结构中的主语从句不可提前。It is said that everything Picassos brush touched turned gold.据说毕加索的画笔刷过的所有东西都能变成金子。It is reported that China has sent anot
6、her manmade earth satellite into orbit.据报道中国又成功地发射了一颗人造地球卫星。(2)It happens.或It occurs to.结构中的主语从句不可提前。It happened that I didnt take any money with me.碰巧我身上没带钱。It never occurred to him that he would get into trouble.他根本没想到他会陷入困境。(3)It doesnt matter how/whether.结构中的主语从句不可提前。It doesnt matter whether he
7、is wrong or not.他是对还是错没多大关系。(4)含主语从句的复合句是疑问句时，主语从句不可提前。Is it likely that it will rain in the evening?晚上可能会下雨吗？(5)当主语从句出现在感叹句中时，宜用it作形式主语。What a shame it is that you cannot stay for dinner!你不能留下来吃饭多可惜呀！常见的用形式主语it引导的主语从句结构有：It is no wonder that.难怪Its a pity that.很遗憾It happened that.碰巧It turned out tha

27、个被普遍接受的理论可以解释它。“大爆炸”发生后，原子开始形成并结合形成恒星和其他天体。第二个阶段是地球是怎样形成的。大约在3845亿年前，漂浮在太空中的尘埃逐渐形成一个固体的球状物。地球活动剧烈，而且经常爆炸。大气层和水出现。水是生命存在的最基本的物质。它同时也溶解有害气体和酸性物质。第三个阶段是关于植物和动物的出现。首先，水生植物出现并繁殖。他们产生氧气，这使水生动物存在。后来，陆生植物使陆生动物出现。它们刚开始产卵，然后成为幼仔。后来，哺乳动物直接生仔。最后一个阶段是人类成为地球上最重要的动物。我们把大量的二氧化碳释放到大气层里，导致了全球变暖。我们必须密切注视事情的进展，制定法律阻止地球变得太热。既然我们已采取措施，我们最终会成功的。让我们振作起来一起努力吧。本部分内容讲解结束点此进入课件目录按ESC键退出全屏播放谢谢使用
