2017高考英语频频出现的易错语法讲解:名词性从句语法精讲

  (一) that引导的定语从句与同位语从句

  定语从句与前面的的名词是修饰与被修饰的关系,“……的名词”,而同位语从句是用来说明前面名词的内容。与that从句同位的名词需要是一些表示事实或概念的抽象名词,如fact,news,belief,truth,reply等。That在定语从句中需要作成分,可用which或who/whom代替,而that在同位语从句中不充当句子成分,只起连接作用。如:

  ①Along with the letter was his promise that he would visit me this coming Christmas. ②Do you still remember the chicken farm that we visited three months ago.

  解析:在句①中,that引导同位语从句解释说明promise的内容,that不充当句子成分,只起连接作用,而在句②中,that在其引导的定语从句中作动词visited的宾语,对先行词the chicken farm起修饰作用。

  感悟:学生之所以在这一点上容易出错,主要还是因为对定语从句的理解不够深刻,分辨不出that在从句中是否充当了句子成分,因此,还需在句子分析上下功夫,并且搞清何谓同位语从句。

  (二) 名词性从句中,关于it作形式主语和形式宾语的易错点

  1. 名词性从句作主语或宾语时,为保持句子平衡,常用it作形式主语或形式宾语。如:

  It’s a pity that he don’t come to give a speech.(形式主语)

  We think it possible that you can finish the job today.(形式宾语)

  2)谓语动词 appreciate, dislike, hate, like, love, make等接由if或when 引导的宾语从句时往往在从句前加上形式宾语it. 例如:I would appreciate it if you could come to my birthday party.

  3)动词hare, take, hide, punish, put等,后接由that 引导的病因从句式,往往在从句前加形式宾语it.

  例如:① I take it that you will be leaving Shanghai soon.

  ② we punished it that we had finished the project ahead of time.

  4)短语动词answer for, count on depend on, insist on, see to等后接有that引导的宾语从句时,需要冠以形式宾语it.

  例如:① I’m counting on it that you will come.

  ② She’ll see to it that he goes ahead.

  注:作形式主语和形式宾语时只能用it.
