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 prolific1 writer, Woodrow Wilson

例:Two unique features of the Arctic they are
        A        B 
  lack of precipitation and permanently2 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 
    A            B   
  one or more sentences related to the same idea.
         C   D
分析:B错,应改为consisting of或which consists of。句中有两个无法连接的谓语动词,而且前一个谓语动词下面没有划线,故改consists为非谓语动词形式或在它前面加which使之成为从句谓语动词。

(三)谓语的缺少
例:Most mammals to maintain a relatively3 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 spawn5 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
