  在SAT中,非谓语动词垂悬修饰是IS题常考的考点,但是学生在考试中确经常出错,是无数考生挥之不去的烦恼,现把非谓语动词垂悬修饰的考点总结如下:

  非谓语动词垂悬分为四种种形式

  形式一:当前后两个句子的主语一致时就可以省略前半句的主语,是主动关系要用doing的形式。

  Traveling through Yosemite, the scenery of waterfalls and granite peaks, which we photographed, was beautiful.

  (A) the scenery of waterfalls and granite peaks, which we photographed, was beautiful

  (B) the waterfalls and granite peaks were the beautiful scenery we photographed

  (C) we photographed the beautiful scenery of waterfalls and granite peaks

  (D) we photographed the scenery of waterfalls and granite peaks, being beautiful

  (E) what we photographed was the beautiful scenery of waterfalls and granite peaks

  在本题中,traveling的主语是人,所以只能再C和D中作出选择,D中毫无根据的用了Being这个自杀词所以错。

  形式二:当非谓语动词的动作发生在谓语动词前的时候要用having done的形式

  The delegates coming this far, they did not want to return without accomplishing something.

  (A)The delegates coming this far, they

  (B)Corning this far, the delegates felt they

  (C)Having come this far, the delegates

  (D)To come this far, the delegates

  (E)The delegates came this far, so that they

  在本题中,代表们先是大老远来了,然后要达成一定的共识。Come发生在谓语动词的动作want之前,所以应该用having come或者after coming的形式,所以选c

  形式三:当时被动的时候,要用done

  Carried by the strong, dry winds of the stratosphere, the 1980 eruption of Mount Saint Helens caused dust that crossed the United States in three days and circled the globe in two weeks.

  (A) the 1980 eruption of Mount Saint Helens caused dust that

  (B) Mount Saint Helens’ eruption in 1980 caused dust that

  (C) dust from the 1980 eruption of Mount Saint Helens

  (D) dust from the 1980 eruption of Mount Saint Helens that

  (E) there was dust from the 1980 eruption of Mount Saint Helens and it

  在本题中,被风携带的是灰尘,所以只能在C与D中做出选择,因为D句缺少谓语动词,故选C。

  形式四:表示目的用to do

  In 1972, to reduce pollution in the Great Lakes, limits having been set by the United States and Canada on the amount of phosphorus that could be discharged into Lakes Erie and Ontario.

  (A) limits having been set by the United States and Canada

  (B) limits set by the United States and Canada

  (C) limits have been set by the United States and Canada

  (D) the United States and Canada have set limits

  (E) the United States and Canada set limits

  本题中,来减少污染的只能是国家,所以只能在D与E中作出选择,因为发生在1972年,应该用过去时,所以选E。

  因此在SAT考试中,如果在做题的过程,在句首出现了doing, having done, after doing,done或to do的形式,要看一下前后主语是否一致,可以起到事半功倍的效果。
