5、er)只作宾语；连接副词连接作用；有意义作状语That /if/whether/as if的区别1.That /if/whether/as if（仅限于表语从句）:均不做句子的任何成分，因此他们所引导的句子结构必须完整。 That 一般用于确定的语气中，引导宾语从句时，口语中的That 可以省略。而其他情况中的That 一般不可以省略。if/whether一般用于不确定的语气。真题1 Some researchers believe that there is no doubt_ a cure for AIDS will be found.(2005粤) A. which B. that C

6、.what D. whether2.Whether和 if的区别连词if/whether：两者均有“是否”之意，在句中都不做任何成分。一般说来， if只能引导宾语从句，而引导主语从句、表语从句或者同位语从句要用whether。即使是引导宾语从句若是与or not直接连用、或在discuss等动词之后，一般也只能用whether不用if。但若宾语从句是否定式时一般用if而不用whether。因此除了引导否定宾语从句只能用if外，我们选用whether来表达“是否”更为保险。真题2 We havent settled the question of _ it is necessary for hi

7、m to study abroad. A. if B. where C. whether D. That 3.连接代词和连接副词的选择 连接代词和连接副词它们都有各自的意思，并在从句中做某一句子成分。连接代词在句子中做主语、宾语、表语和定于，连接副词在句子中做状语。因此，选择连接代词和连接副词时，要综合考虑句子意义的需要和句子成分的需要两个方面，才能做出正确的选择。 真题3 See the flags on top of the building? That was _we did this morning. A. when B. which C. where D. What真题4 Pleas

8、e remind me _he said he was going. I may be in time to see him off. A. where B. when C. how D. what4.其他情况：（1）which不引导同位语从句，它在主语、表语、宾语从句中长用作定于，即修饰一名词，表示名词有特定的范围。 （2）why引导表语从句时，从句表达的是结果； because引导表语从句时，从句内容表达的是原因。如： His car broken down on the way .Thats why he came late for school. He didnt come to wo

9、rk those days . Thats because he was ill. （3）what /who/when/where等引导名词性从句含有疑问语气；而 whever之类 连接词不表示疑问。 whatever/whichever前者强调“无论什么” ，相当于anything that，并不说明范围，而后者既可以指人也可以指物，既可以单独使用，又可以修饰名词，也可以和of短语连用,表示某一范围中的无论哪个。真题5 team wins on Saturdays will go through to the national championships . A .no matter wha

10、t B . no matter which C .whatever D .whichever that/whatThat与what 二者 都可以引导主语、表语、宾语和同位语从句。that只起连接作用，不充当任何成分。而what在意思上相当于all that (all the things that或 the things which)，译为的东西或事情。除起连接作用外，在名词性从句中充当主语、宾语或者表语。 what (the things which) we get seems better than what (the things which) we have.【考点四考点四】名词性从句
