1.高二英语下学期知识点整理


  引导的主语从句的what可修饰名词吗?回答是:有时可以。这类用法具有以下几个特点:

  1. 表特指

  所谓表特指,就是说此时的what 在用法上大致相当于the。如:

  What possessions I have are yours.=The possessions I have are yours. 我的所有的财产都是你的。

  2. 表“微量”

  有时不仅表特指,而且还表“微量”,即含有“量不多”之意。如果将“特指”和“微量”结合起来,该结构的意思就是“虽不多,但全部”,有时可译为“仅有”。如:

  What ideas he has are his wife’s. 他仅有的一点想法都是他妻子的。

  What friends she has are out of the country. 她有的那些朋友全在国外。

  这类“what+名词”结构并不是总具有“微量性”,即有时有,有时没有。如果要想明确或强化这种微量性特点,我们可以该结构的名词前加上表示微量的修饰语few(用于复数名词前)或little(用于不可数名词前)。如:

  What few friends she has are out of the country.=The few friends she has are out of the country. 她仅有的几个朋友都在国外。

  What little free time he had was spent with the family.= The little free time he had was spent with the family. 他仅有的一点空余时间都是与家人在一起度过的。

  whatever引导主语从句时,意义相当于anything that,通常译为“……任何东西(一切事情)”“……所……的一切(所有)”“无论什么……都”。如:

  What ever she says goes. 一切她说了算。

  What ever I have is yours. 我的东西都是你的。

  What ever she did was right. 她做的一切都是对的。

  What ever I have is at your service. 我所有的一切都供你使用。

  What ever you want is fine with me. 无论你要什么对我都合适。

  注意,不要与whatever引导让步状语从句(=no matter what)时的用法相混淆。如:

  What ever happens, I must be calm. 不管发生什么事我都要镇静。

  What ever you say, I won’t believe you. 不管你说什么,我决不相信你的话。

  关系代词

  两种可用来引导从句并将从句和主句连接起来的代词

  这样的代词一方面在从句中用作句子成分,可作主语、宾语、定语等;另一方面又起连词的作用。这样的代词有关系代词和疑问代词两种。

  关系代词概说

  关系代词有who,whose,whom,that,which等,用来引导定语从句。它们在定语从句中可用作主语、宾语、定语或表语;另一方面它们又代表主句中为定语从句所修饰的那个名词或代词(这样的名词和代词叫做先行词)。如:

  The man who is talking with Mr. Brown is an eye Specialist和布朗先生谈话的那个人是个眼科大夫。(关系代词who在从句中用作土语,它的先行词是man)

  He is the comrade whom you have been looking for他就是你要找的那位同志。(关系代词whom在从句中作宾语,它的先行词是comrade,whom在口语中一般可省去)

  The old man whose son is in the navy used to be carpenter.儿子在海军的那位老人过去是个木匠。

  (关系代词whose在从句中用作定语,先行词为man)

  The film which I saw last night is about a young teacher.我昨晚看的那部电影说的是一个年轻教师的事。(关系代词which在从句中用作宾语,先行词为film, which在口语中可省略)

  This is the plane that will fly to Tokyo in the afternoon.这是下午要飞往东京的飞机。(关系代词that在从句中用作主语,先行词为plane)

  1.Nobody knew that it was going to be different from other planets going to be different from other planets going round the sun.

  going round the sun 为现在分词短语定语,表示一般的动作。 Eg: Men breaking the law will be punished. 现在分词短语,也可表示进行的动作

  2. Weather life will continue on the earth for millions of years to come will depend on whether this problem can be solved.

  for millions of years to come 中不定式to come 作定语,与前面的名词有逻辑上的主谓关系。

  Eg: She is the last person to tell lies.

  3.The problem was that the earth became violent because it was not clear whether the solid shape was to last or not.

  The problem was that …, that 引导表语从句,that 只起连接作用,无意义,但不能省略。 Eg: The trouble is that we are short of money.

  4.As the earth cooled down, water began to appear on its surface.

  as conj. 随着,在…期间;由于,因为;尽管,即使;当…的时候;像…一样 5. That made it possible for life to begin to develop.

  it 是形式主语,真正的主语是不定式to begin to develop. Eg: He thinks it’s his duty to help others.

  keep (stay) still 保持不动

  lie (stand) still 躺着(站着)不动
