if 与whether引导宾语从句作动词宾语时，二者常可通用，但在以下条件下不可：
引导__________从句、__________从句及位于句首的_______从句，只用whether.(if, whether引导的主语从句都可置于句尾，用it作形式主语置于句首。)
宾语从句位于________后或作discuss的宾语时，只用whether. 与_________连用，只用whether.
与________直接连在一起使用，只用whether. 四．名词性从句的语序 1. That's_____.

1.The teacher asked who _______(break) the window.
2.She says (that) she ________(work) from Monday to Friday. 3.The manager asked what _______(be) the matter.
当主句的谓语动词是一般现在时或将来时时，其宾语从句的时态可以是任何适当的时态；当主句的谓语动词的时态是一般过去时的时候，其宾语从句的时态一般要用任一适当的________时态 六．区别that引导的同位语从句和定语从句
1.引导同位语的连词that在句中_____________，而在定语从句中， that充当的可以是从句的主语或宾语等
2. 同位语从句是对前面名词的内容的具体说明，而定语从句是对前面名词进行修饰，解释为“….的” 3. 连词that在同位语从句中_____省略,而在定语从句中当它充当宾语时______省略。 1.We expressed the hope that they had expected.
2.We expressed the hope that they would come to visit China again. 七．难点解析 1.that的省略问题
that引导宾语从句时可省，引导主语从句，表语从句，同位语从句时，一般不可省略。
1）当一个句子中有两个或多个并列的宾语从句时，引导第二个及其以后几个宾语从句的that均不可省略。that引导的宾语从句作介词宾语时，that不可省略。
(注意：that从句一般只作介词but, in, except, besides的宾语，若that引导的宾语从句作其他介词的宾语时，常用it作形式宾语。)
