【解析】GMAT句子改错高频考点讲解
说到SC的高频考点,逻辑肯定使其中之一,且逻辑考点也是SC中较为重要的考点。下面就由申友GMAT的Regina老师对逻辑考点进行讲解:
1、如何识别逻辑考点:
1)全句划线
2)主语改变
3)句间关系改变
4)识别不出其他考点
2、逻辑常见的三种错:
1) 主从句互换
2) 句间关系错
3) 句子内部逻辑搭配错
今天主要对第三种常见错误:句子内部逻辑搭配错进行讲解。
例1:主宾搭配不当
Glaciers form when the snow, sleet, and hail that fall in a given climatic region exceed the amount capable of being lost through evaporation or melting.
A the snow, sleet, and hail that fall in a given climatic region exceed the amount capable of being
B a given climatic region's fallen snow, sleet, and hail exceeds the amount able to be
C the amount of snow, sleet, and hail that falls in a given climatic region exceeds the amount
D the snow, sleet, and hail in a given region exceeds the amount able to be
E a given climatic region exceeds the amount of snow, sleet, and hail that falls and cannot be
本题中可以发现比较词exceed,其连接的两者需要在语法和逻辑上保持的对等。能产生“超过(exceed)”关系的两者一定要对等,即“数量”超过“数量”。而不是能是“雪”超过“数量”,可以排除(A)(B)(D)(E),答案为(C)。且BD还有主谓不一致的问题。
例2:主表搭配不当
Once they had seen the report from the medical examiner, the investigators did not doubt whether the body recovered from the river was the man who had attempted to escape from the state prison.
A did not doubt whether the body recovered from the river was
B have no doubt whether the body recovered from the river was
C had not doubted that the body recovered from the river was
D have no doubt whether the body recovered from the river was that of
E had no doubt that the body recovered from the river was that of
考点:逻辑语义
这道题,如果你知道doubt的用法那固然是很好的,但是,即便 你不知道doubt的用法,你也是可以根据语义来做这道题的,这道题的切入点在于为划线部分,the man,到底是the body was the man,还是 the body was that of the man,很显然,逻辑上, the body was that of the man是正确的,答案在DE里选,根据主句和从句的一致性,选E.
分析:doubt的用法是have no doubt that...表示“毫无疑问”,若前面没有否定词,doubt后接whether;句意是:当调查者看到尸检报告,他们深信从河里捞出来的尸体是那个试图从监狱里逃跑的男人的尸体;
the body 是男人的body,用that来代替;
选项:
A.not doubt whether用法错误;the body was the man语义不合理;
B.同A;
C.the body was the man语义不合理;
D.have no doubt后不接whether;
E.正确;
