　　2、熟悉并掌握复合句即名词性从句（主语从句、宾语从句、表语从句、同位语从句），定语从句和状语从句。

　　什么叫复合句

　　由一个主句和一个或一个以上的从句构成的句子叫复合句。在复合句中主句是全句的主体，从句是全句的一个成分，不能独立。

　　从句通常是用关联词来引导的。在这里关联词还起联系从句和主句的作用。

　　主从复合句（Complex Sentences）

　　一、从句的种类：

　　（1）It + be + 形容词 + that从句

　　（2）It + be + 名词词组 + that从句

　　（3）It + be + 过去分词 + that从句

　　It is important that we should go to the school to talk with the teacher.

　　2、表语从句，即名词性从句放在表语位置就是表语从句，需要注意的，主语

　　是 reason时，表语要用that引导而不是because．

　　The reason why he was late was that he missed the train by one minute this morning .

　　3、宾语从句that 常可以省略，并且注意时态呼应，当主句为过去时时，从句

　　时态一定往前推移，不可出现现在时或现在完成时。

　　The teacher told us that Tomo had left us for America．

　　4、同位语从句注意与定语从句区别，同位语从句对前一名词做补充说明，在

　　从句中无语法位置，而定语从句所修饰词在从句中占一语法位置如：

　　The idea that one can do the work without thinking is wrong．( 同位idea在从句中

　　无位置，而从句只是具体说明idea的内容）。

　　The idea that you put forward at the meeting is wrong ．(定语从句，idea做put forward 的宾语)。
