高一牛津版名词性从句语法小结

　　名词性从句包括主语从句、表语从句、同位语从句和宾语从句，它是高考考题中复现率最高的语法现象之一。近年来高考对名词性从句的考核主要体现在下列几方面：

　　(1)考查主句和从句间的连词使用，尤其是使用that，if，whether，what，whatever等连接词的使用情况。

　　(2)名词性从句中主句和从句中时态的一致。

　　(3)从句在主句中位置以及在主句中的语序。

1．that在名词性从句中的几种使用情况。

2．what连接词的语言意义和语法功能。

3．whether在名词性从句中的使用场合和区别。

4．whoever和whomever在名词性从句中的语法功能。

5．what和which在具体语境下意义的不同。

在通常情况下，that引导主语从句时，常常用it做形式主语，而将that从句置于句尾。

That her mother was ill made her very sad.

It is certain that he will succeed.

三．whether引导的主语从句
