SAT语法之because的用法实例讲解

  SAT语法在SAT考试中有这举足轻重的地位,sat语法的运用十分重要,今天小编就给大家实例讲解because的用法。

       

      Because of ignoring its potential, biofeedback is a medical therapy most physicians reject.


  A Because of ignoring its potential, biofeedback is a medical therapy most physicians reject.


  B Biofeedback is rejected by most physicians because of their ignoring its potential.


  C Most physicians, because of ignoring the potential of biofeedback, and rejecting it.


  D Most physicians reject biofeedback because they ignore its potential.


  E A medical therapy rejected by most physicians, caused by ignoring its potential, is biofeedback.


  Because的出题形式通常有三种:种是单独的because;第二种是because of doing;第三种是because sb/ one’s doing。这三种形式的考察点通常是这样,because的后面一定要接一个完整的句子,because of doing涉及到逻辑主语的问题,而最后一种不是好的表达,可以直接排除掉。


  如果because后面的从句没有什么错误,那么我们通常是选because 引导的从句的选项,不倾向于选because of doing。其实也就是说,通常,because优于because of doing优于because of sb/ one’s doing。


  有很多童鞋不明白,为什么because of sb/ one’s doing一定是错的。我们都知道SAT喜欢直接的动词表达,所以对于这种表达方式而言,既出现了sb,也出现了动词的ing形式,那就不如去掉of,直接说因为某人做了什么事,最直接的主谓表达。


  根据上面的解释,我们来看一下这个题目。A选项because of ignoring..., 可以看出来ignoring的主语应该是physicians, 但是后文句子的主语却是biofeedback, 所以逻辑主语出问题了,排除掉。B选项是because of one’s doing, 必错,排除掉。C选项的because of的逻辑主语倒是没有问题,但是看完之后发现这句话没有谓语动词,所以排除掉。


  D选项看来看去没有什么明显的错误,而且也是because引导的原因状语从句的形式,有直接的主谓宾结构,保留。E选项中没有because,有非谓语结构——caused by,我们需要找一下它的逻辑主语,应该是medical therapy, 但是medical therapy显然不是ignoring its potential引起的,逻辑表达有问题,所以排除掉E选项,最终答案为D。
