连接代词

who(ever),whom(ever),which(ever),what(ever)连接副词where,when,why,how1）从属连词：that，whether等.that

引导主语从句只起引导作用，本身无实际意义，在主语从句中不充当任何成分，但不能省略。

注意:

由that引导的主语从句有时为了使句子结构平衡,避免“头重脚轻”,常用it

作形式主语,而把从句放在后面。例如:

1.That

Itisasurprisethat…令人惊奇的是…

Itisafactthat……是事实

Itiscommonknowledgethat……是常识*_______________(很遗憾)welostthematch.*______________(这是事实)hecheatedintheexam.ItisapitythatItisafactthat2)Itis+adj.+从句
