Presentation 1、 名词性从句的定义 由连接词引导,在复合句中起_作用的从句叫名词从句(Noun Clauses)。它在复合句中能充当_、_、_、_等,因此根据它在句中不同的语法功能,名词从句又可分别称为_、_、_和_。 二、位置及概念 1.主语从句在复合句中充当_语; 2.表语从句在复合句中充当_语,一般在_ 后; 3.宾语从句在复合句中充当_语,且一般在 _ 或_ 后。 4.同位语从句一般在_后,解释或补充说明该名词的内容。 Exercise:请判断出下列的句子属于哪种从句。 1.

(2) From the space, the earth looks blue. This is _ about 70percent of its surface is covered by water. (3) About 70 percent of the earth’s surface is covered by water. That is _ it looks blue.
