一、名词性从句


名词性从句主要分为四大类:主语从句、宾语从句、表语从句和同位语从句。


<一>主语从句


 1.that引导的主语从句


  that引导的主语从句既可以放在句首也可以放在句末,在实际应用中我们常常采用it形式主语的形式。


  例句:That he passed the English test is true. 千真万确,他通过了英语考试。


       →It is true that he passed the English test.


 2.形式主语的四个主要句型


 (1)It + be + 名词 + that从句


  例:It is a pity that…可惜的是


  可应用于此句型的名词还有fact / shame / honor 1 / question等。


 (2)It + be + 形容词 + that从句


  例:It is certain that… 很肯定


 可应用于此句型的形容词还有clear / better / natural / important 等。


 (3)It + be + 动词的过去分词 + that从句


  例:It is said that…据说


  可应用于此句型的过去分词还有believed / known 2 / reported等。


 (4)It + 不及物动词 + that 从句


  例:It seems that…好像是


  可应用于此句型的不及物动词还有happen / appear 等。


 3.wh-引导的主语从句


  例句:Where we will go hasn’t been decided 3. 我们要去哪儿还没定下来。


<二>宾语从句


 1.that引导的宾语从句


  that常用来引导宾语从句,通常that可以省略。


  例句:He has told me that he will go to Shanghai tomorrow.


     他已经告诉我他明天要去上海。


  注意:demand、order、suggest、decide等表示要求、命令、建议、决定等意义的动词后,that从句常用“(should) + 动词原形”的结构(参考“虚拟语气”部分)。


 2.wh-引导的宾语从句


  例句:I want to know what he has told you.


      我想知道他告诉了你什么。


 3.形容词后面所跟的宾语从句


  某些动态形容词(afraid、confident、aware、certain、sure、doubtful等)在句中做表语时,后面可跟宾语从句。


  例句:I am confident that I can get the job.


      我有信心我可以得到这份工作。


<三>表语从句


 1.that引导的表语从句


  基本结构:主语 + 系动词 + that从句


  例句:The fact is that we have lost the game.


      事实是我们已经输了这场比赛。


 2.wh-疑问词引导的表语从句


  例句:That is why I tell you the news..


      那就是我为什么告诉你这个消息的原因。


 3.从属连词as if、because、just as等引导的表语从句


  例句:It is because I have ever heard of the story.


      那是因为我曾经听说过这个故事。


<四>同位语从句


同位语从句通常由that引导


  可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。


  例句:The news that we won the game is exciting.


      我们赢得这场比赛的消息令人激动。
