2、 he left (or not) is unknown(3)当主语从句作主语时，谓语动词一般用第三人称单数，下面这个句型例外。What we need is more time and money.What we need are many more books.2.表语从句：表语从句出现在系动词后，充当表语。The trouble is that we are short of money.Go and get your coat. Its where you left it.(1) 引导表语从句除了上述三类词外还有because, as if/ as though等等The reason

3、 (why/for which.) is that It/This/That is because(2) 连系动词“appear, look, seem”的两个常用句型It seems/appears that.It looks/seems as if/as though(与事实相符用陈述语气，与事实相反用虚拟语气)(3) as 也可以引导表语从句Things are not always as they seem to be3. 宾语从句：及物动词，形容词和介词后加宾语从句作其宾语。(1) 宾语从句时态与主句相呼应，但宾语从句表示的是客观真理或普遍现象除外The teacher told u

4、s that the earth moves around the sun(2) 连词whether和 if可以互换，但注意下列情况连词后紧跟or not时用whetherI want to know whether or not they will come.作介词宾语是用whether引导宾语从句He was interested in whether he saw her there.连接词后直接加不定式，不能用if只能用whetherHe doesnt know whether to stay or not.如果宾语从句是否定时，一般用if引导I care if he will not

5、 attend the meeting.(3) 当宾语从句后带宾补时，要用“主语+谓语+it +宾补+that-clause,that不可省略I think it certain that she will do well in her exam.(4) 当主语是I, we ，主句用think, believe, suppose, expect, imagine五个动词时，用否定转移I dont think he will win the game, will he?(5) that在宾语从句常可以省略，但由and或 but连接两个或多个宾语从句时，仅可以省略第一个连词thatHe said

6、(that) he had eaten nothing but that he wasnt hungry.(6) 注意区别if引导的宾语从句和条件状语从句I dont know if he will come.If he comes, Ill let you know.4.同位语从句，在句中作某些名词的同位语，对前面的名词进一步说明。用在下列名词 fact,news,idea,hope,believe,hope,thought,doubt.truth,order,suggestion, word etc.(1) There is no doubt that he will come.There

8、 told us.when, where引导的同位语从句与定语从句的区别：在定语从句中，when, where前有分别表示时间、地点的先行词；而在同位语从句中无此对应关系They have no idea at all where he has gone.(同位语从句)Go and get your coat. Its in the place where you left it.(定语从句)5. 疑问词-ever既可以引导名词性从句，也可以引导让步状语从句，而no matter+疑问词只能引导让步状语从句No matter where I go, my heart is towards Ch
