二、学习主语从句应该注意的几个问题
1)引导词that与what
what既有引导主语从句的作用,同时又在从句中作句子成分(主语、宾语、表语等).这时what相当于all that/everything that...,常译成"所……的(东西、事情、话等.)";而that只起连接作用,本身无实际意义,在从句中也不担当任何句子成分.但that引导的主语从句放在句首时,不能省略that.
例如:
What is done can t be undone.
(谚语)已成定局,无可挽回.
What we can t get seems better than what we have.
我们得不到的东西似乎比已得到的要好.
That we should work out a plan to deal with the present serious situation is important.
