2、e are going next week. 我们下星期走是真的。 解析：真正的主语是 that we are going next week，前面的it是形式主语。宾语从句：在复合句中作宾语的名词性从句，通常放在主句谓语动词及物动词和介词之后。例如：1. We all know what he is. 我们都知道他是干什么的。 解析：what he is作及物动词know的宾语从句。 2.

3、在复合句中作表语的名词性从句，放在系动词之后，一般结构是：主语+联系动词+表语从句例如：1. His question is where he can buy a house. 他的问题是他能在哪里买房子。 解析：where he can buy a house是联系动词is后面的表语从句。 2. This is why we cant get their support. 这就是我们得不到他们支持的原因。 解析:why we cant get their support是联系动词is后面的表语从句。同位语从句：是用以说明所修饰名词的具体内容的，它与被修饰的词语通常可以划等号。例如：We he

4、ard the news that our team had won. 我听说了我们球队获胜的消息。 为了思维的连贯性，此专题我们不以从句的分类来讲，而以连词的分类讲。引导名词性从句的连词主要有以下几类： what, how, who, when, where, why,whose, whichthat在句中没有如何意义，只起连词的作用 是否5.疑问词+ everwhatever、whoever、whomever、however、whenever、wherever、whichever一、具有词汇意义的连词 1.

20、, believe, suppose等表示“意念，信念，揣测的动词时，宾语从句的否认要提到主句上来，反义疑问句那么要根据宾语从句的主谓进行变化。a. I dont think your answer is right, is it? 我认为你的答案不对，是吗？b. I dont believe you can go next year。 我相信你明年不会去c.

23、性从句中 又充当一个成分。 我父母把我培养成我现在的样子。 解析：这里的what相当于the person who/that7. After what seemed five years , he came .

27、这类完成句子题：1_ (不管发生什么事) , I will go. (what 答案: No matter what 解析：在做这道题时，许多学生的答案可能会是Whatever. 在这里是引导的状语从句，但 由于是要求用括号内的单词完成句子，所以答案就只能是No matter what 2)_ (不管你什么时候方便, please come to my home .(when) 答案：No matter when it is convenient to you。 解析：在这里就不能是Whenever it is convenient, 理由是括号里给的是when。 七，表语从句的补充：1.Th
