宾语从句的时态呼应
同位语从句
名词从句
在复合句中起名词作用的从句叫名词从句 (Noun Clauses）。名词从句的功能相当于 名词词组, 它在复合句中能担任主语、宾语、 表语、同位语、介词宾语等，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 主语从句、宾语从句、表语从句和同位语从句。
名词性从句在功能上相当于名词
inspired us. 5.I don’t think it necessary _t_h_a_t_____ you should
read English aloud. 6.He told me __(_t_h_a_t)____ his father had died
and ____th_a_t____ he had to make a living alone.

How was he successful is still a puzzle. ( F ) How he was successful is still a puzzle. ( T )

Could you tell me where he lives?

2.同位语从句对中 心词的内容作进一步的解释和说明， 表明中心词的具体内容。引导同位语从句的that 在同位语从句中不做任何成分,只起连接作用,无具体 含义,且不可省略.

三、同位语从句的引导和辨别
1.同位语从句的格式：n.+ 连接词 + 从句 2.能接同位语从句的名词有：fact、idea, news,
information, order, belief, suggestion, advice等 3.连接词通常是that,也可根据含义选用
whether, what, when, where 等来引导同位语从句。
8. I don’t know w__h_e_t_h_e_r to go.
其它连接代词和副词的连用
主要根据名词性从句中的具体意义,正确的 选择who、which、when、where、why、 how 等连接词，这些连接词既具有疑问含义， 又起连接作用，同时在从句中充当各种成分。

引导词that 的省略
