3、lear.连接代词What（ever）当what引导主语从句作主语时，指物，谓语动词一般用第三人称单数，下面这个句型例外。Eg.

4、句，它们分别在从句中担任主语、宾语和状语，不能省略。注意，翻译时，不能把它们翻译成疑问句。WhereEg. Where to meet him is still not decided yet.WhenEg. When he will be back depends on the weather.WhyEg. Why he did it remains a mystery.HowEg.

6、去分词主语从句：Eg.It is still a question whether she will come or not. It is strange that you should like him. It is still unknown which team will win the match.另外，还有一些比较多见的结构： It turned out that； It has been proved that; It happened/occurred that； It is well-known that等等而强调句则不同，它的结构是：Itbe被强调部分that从句 强调主语：
7、It is the times that produce their heroes.时势造英雄 强调宾语：It is English that Prof.Lin teaches us. 强调状语：It was in shanghai that I saw the film. 判断是否是强调句有一个方法，就是将that以后的“句子的其余部分”拿出来单独看，看有没有缺成分，缺的是什么成分，再把谓语动词后面that前面的那部分，带到你认为缺成分的地方，如果放进去是一句完整的句子了，那就说明是强调句。主语从句的时态主语从句通常被看作一个整体,主句的谓语动词用单数形式. That they will c
8、ome is certain.由who, whoever引导的主语从句的单复数要视从句中的单复数而定.Whoever say that are to be punished.Who are going there have been decided.What 引导主语从句时,主句谓语动词的单复数由表语的单复数决定.What he wants are these books.What he wants is some water.What 与that 在引导主语从句时的区别 What 引导主语从句时在从句中充当句子成分，如主语、宾语、表语；而that 则不然。Eg.

9、yesterday is right.主语从句不可位于句首的五种情况a）if 引导的主语从句不可居于复合句句首。 b）It is said , （reported） 结构中的主语从句不可提前。It is said that President Jingo will visit our school next week. c）It happens, It occurs 结构中的主语从句不可提前。It occurred to him that he failed in the examination.

11、ay calm.Whetherif不能引导表语从句，只能用whether 来引导Eg.

14、，只能用whether 来引导。表语从句时态不像宾语从句，在有表语从句的复合句中，主句时态和从句时态可以不一致。 （）: The question is who will travel with me to Beijing tomorrow. （）: The question is why he cried yesterday.表语从句常用句型辨析a）“That is why.”与“That is the reason why.”同义， 只不过从语法结构上讲，“That is the reason why.”中why引导的是个定语从句， 将其中的the reason去掉则与“That is why.”结构一样， 例如： That is （the reason） why I cannot agree. 这就是我不能同意的理由。 b）“That is because.”句型中从属连词because引导的名词性从句在此作表语， 这也是个常用句型， 意为“这就是为什么/因为”。“That is because.”与“That is why.”之间的不同在于“That is because.”
