精品资料欢迎下载专题九名词性从句常考点在复合句中起名词作用的从句叫作名词性从句。它包括主语从句、宾语从句、 同位语从句和表语从句。名词性从句是英语中的一个重要语法项目， 在历年的高考中几乎都涉及到。引导名词性从句的连接词可分为三类：连接词that，whether，if(不充当从句的任何成分 )；连接代词 what，whatever，who，whoever，whom，whose，which；连接副词 when，where，how，why。1It is.和 There is. It is.句型中 it 为形式主语，真正的主语为动名词、不定式或从句，而 There is意为“ 有” ，有时 be也可以用 exist，remain 等替代。用 it，there填空：_ is a pity that he was absent. _ is a fact that he has lied to you. _ is no wonder that he is so excited. _ is no need to worry about it. _ is no sense/point (in) arguing with him. _ is no doubt that he has gone. 【答案】 ItItItThereThereThere 2从句作主语时的谓语动词形式主语从句作主语相当于第三人称单数作主语，谓语动词用单数； 如果由 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；由两个或多个连接词引导一个主语从句，谓语动词用单数。用所给词的适当形式填空：That the president is coming _(excite) all of us. How close parents are to their children _(have) a strong influence on their character. When and where the meeting will be held _(not decide) yet. 【答案】 exciteshasisnt decided/hasnt been decided 精选学习资料 - - - - - - - - - 名师归纳总结 - - - - - - -第 1 页，共 10 页精品资料欢迎下载3宾语从句的时态和语序宾语从句中的时态要注意呼应。当主句中的谓语是现在时， 从句根据自身的句子情况，而使用不同的时态。当主句中的谓语是过去时态，从句则要用相应的过去时态(如一般过去时，过去进行时，过去将来时等)；当从句表示的是客观真理、科学真理、自然现象，则从句仍用现在时态 .宾语从句语序要用陈述语序(what is/was the matter除外)。The photographs will show you _ A. what does our village look like B. what our village looks like C. how does our village look like D. how our village looks like Someone is ringing the doorbell. Go and see _A. who is he B. who he is C. who is it D. who it is Hello，I didnt know you _(be) in London. How long have you been here? I thought he _(be) coming tomorrow.

The news _ our team won the game excited us. The fact _ he collected was surprising. The fact _ he said nothing was surprising. There is a chance/possibility _ he will lose the game. _ are that he will lose the game.

Whether he comes or not ，we will begin our party on time. 2. whether和 that的区别： that 表示事实，而 whether 表示疑问。完成下列句子： _ they are twins is clear. _ they are twins is not clear.
