  专题九名词性从句

  

连接词that, whether, if引导的名词性从句   

  1.that引导的名词性从句

  (1)that在名词性从句中不作任何成分,引导宾语从句时有时可以省略,引导主语从句、表语从句和同位语从句时不能省略。

  I think that you should turn to the teacher for help.(that不充当任何句子成分,也无实际意义)

  我认为你应该向老师寻求帮助。

  (2)that引导主语从句时,常用it作形式主语,常见句型有:

  ①It+be+形容词(necessary/right/likely/unlikely/wrong/important/certain等)+that从句

  It is wonderful that all of you have passed the difficult exam!

  你们都通过了这次很难的考试真令人高兴!

  ②It+be+名词(短语)(a pity/a shame/a surprise/no wonder等)+that从句

  It is a pity that you have missed the wonderful lecture.

  你错过了这么精彩的演讲真遗憾。

  ③It+be+过去分词(said/told/reported/decided等)+that从句

  It is suggested that the lab building (should) be built next year.

  有人建议实验楼明年修建。

  ④It+特殊动词(seems/appears/happens/matters)+that从句

  It appears that they have made the same mistake.

  好像他们犯了同样的错误。

  ①It is necessary/strange/important/natural etc.+that ...

  ②It is a pity that ...

  ③It is suggested/requested/required/proposed/desired etc. +that ...

  (3)动词find, feel, think, consider, make, believe等后面有宾语补足语时,需用it作形式宾语而将that引导的宾语从句后置。

I think it necessary that we take plenty of boiled water every day.我认为我们每天喝
