专题一定语从句和名词性从句三，定名从解题两步法：1）判断从句成分是否完整，排除一部分选项。

2）定语从句看先行词做最终选择，名词性从句看题意做最终选择。

四，注意特殊问题。

1），定语从句中that的两用两不用原则：两用：1）先行词是最高级，序数词，不定代词或有人有物时；2）先行词被以上词或the only/the very/the last修饰时；两不用：1）在非限制性定语从句中不用that；2）关系词置于介词之后不用that；2），在定语从句中，当that/which/who/whom做从句宾语的时候，可省略。

在宾语从句中，that可省略。

其他情况下，只要是从句必须要有引导词。

3），定从中用“介词+which/whom”引导从句时，介词根据先行词和从句之间搭配来确定。

如：He is the boy with whom I played yesterday.(搭配：I played with the boy yesterday.) 4)，定语从句中先行词是the way 且从句完整时，引导词有that/in which/省略。

5），定语从句中where/when/why可以用“介词+which/whom”代替。

如：this is the room where I lived=This is the room in which I lived.=This si the room that/which/省略I lived in.6)，定语从句和同位语从句的区别：（1）定语从句可以修饰任何名词或代词，而同位语从句只能跟在抽象名词之后。

常用抽象名词有：fact, feeling, idea, news, hope, belief, thought, truth, doubt, suggestion, warning, reason, question, possibility，decision，promise等。

（2）定语从句是对先行词的修饰限定。

而同位语从句只是对抽象名词的内容进行补充说明。

如：This is the news that he is a robber.(同位语从句)。

This is the news that he told me.(定语从句)。

7），名词性从句中whether和if的区别。

（1）whether在名从中通用，无限制。

（2）if只用于宾语从句中。

（但当宾语从句跟在介词或discuss之后、从句中有or not或者与to do连用，也只能用whether。

）(3)whether.......or......可引导让步状语从句，if可表“如果”，引导条件状语从句。

8）doubt后的从句：在肯定句中，用if/whether。

否定句中用that。

疑问句中用that。

9）疑问词+ever：(无论........可引导名词性从句和让步状语从句)，no matter+疑问词：（无论........，只能引导让步状语从句。

）10）名词性从句中的特定句型1）主语从句：用it 作形式主语的句型A,It + be + adj.//n. +主语从句It is natural // important // necessary // surprising // strange // funny + that 引导的主语从句，从句的谓语动词可以用(should) + do // be done 的形式B, It + be +announced/believed/expected/hoped/decided/reported/said/shown +主语从句It is requested that Miss Wang (should) give a speech at the meeting.C,It (so) + happened +主语从句It happened that I was out that day.D, It + matters //mattered (much//little) +主语从句It matters much whether you are determined or not if you want to succeed.E,It + doesn’t//didn’t matter +主语从句It doesn’t matter whether we have money or not..F,It + seems//seemed (to sb) + adj.//n. + 主语从句It seems to me quite strange that he should be so rude to his classmates.G, It + depends +主语从句It depends whether we can do it with fewer workers and less money.H, It is no wonder + that主语从句It is no wonder that he got high marks in the exam.R,It makes no // little // great … difference +主语从句It made great difference whether he would come to my birthday party or not.2）宾语从句：用it 作形式宾语的句型J, make// find// feel // think // consider // believe // suppose +it + adj. // n. +宾语从句I think it wrong that the young don’t respect the old.K, 主语+ hate /dislike/ depend on + it +宾语从句I hate it when people speak with their mouth full.L take it for granted that.........I will appreciate it if you..........When it coms to...........3）表语从句：M,It looks/looked as if-clauseIt looks as if // as though someone were running after her now.N,It seems//seemed that-clauseIt seems that he is very disappointed.O,It appears//appeared as if/that-clauseIt appeared that he could do everything possible to help the poor.4) 同位语从句：P, have no idea +同位语从句Sorry, I really have no idea where she lives.Q, have an idea + that引导同位语从句I have an idea that she won’t leave me whatever happens.R, there is no need// no doubt + that引导同位语从句There is no need that you worry about his safety, you see, he is a big boy now.There is no doubt that he is devoted to you.S, Word came +that引导同位语从句Word came that the playground in our school would be replaced by a gym.
