托福考试改错题常考要点及例题分析(下)Ⅰ

  五、句子的结构  句子的结构主要考查四个出题方向。
  (一) 主语的重复  名词+代词+谓语,这个代词永远是重复的主语,永远是错的
  例:Woodrow Wilson he was an idealist who refused to make any
            A      B     
    compromises concerning the establishment of the
            C          D
    League of Nations.
  分析:代词he不是同位语,主语重复;如果是下面这样的主语,那么便是主语同位语
  A prolific writer, Woodrow Wilson
  例:Two unique features of the Arctic they are
          A        B 
    lack of precipitation and permanently frozen ground.
      C         D
  分析:选项B中的they和前面的主语two unique features重复
  (二)谓语的重复  完整的句子后面又多了一个谓语,往往改为定语从句
  例:A paragraph is a portion of a text consists of
   
  例:Most mammals to maintain a relatively constant body
            A     B   
    temperature, regardless of what the air temperature might be.
           C               D
  分析:A错,应改为maintain。句中缺谓语动词,故去掉不定式符号to 使maintain变成谓语动词。
  (四)主句的重复  主句的重复总是考even, instead, during, despite等引导的句子, 但是实际上它们无法把两个句子连接起来,因为它们都是副词或者介词,连接两个句子应该用连接词连接
  例:Salmon spend most of their adult lives in salt water, despite
        A         B        C  
    they return to their freshwater birthplaces to spawn and die.
       D
  分析:C错,应改为though。despite是介词,后面一般接名词作宾语,而在句中它后面却跟着一个完整的句子,所以改为连词though。
  例:Solar eclipses occur during the Moon's shadow
A   B      
    sweeps across the face of the Earth.
        C    D
  分析:B错,应改为when或as。介词不能引导条件状语从句,根据题意改为从属连词when或as。
  例:Even many early leaders of the United States have provided
     A                     B 
    names for towns, only George Washington
 C
    is remembered in the name of a state.
    D
  分析:A错,应改为Even though。even为副词,不能引导从句,根据题意,改为引导让步状语从句的Even though。
