GMAT高频词汇twice用法实例讲解
In the 1980s the rate of increase of the minority population of the United States was nearly twice as fast as the 1970s.
(A) twice as fast as
(B) twice as fast as it was in
(C) twice what it was in
(D) two times faster than that of
(E) two times GREater than
选项分析:
A中是twice as fast as the 1970s 在这里是rate和1970s比较,是不对的,
DE都是错误搭配用法
然后看the rate of increase of the minority population of the United States
C选项的意思是:A的人口增长率是B的两倍
B选项的意思是:A的人口增长率是B的(人口增长率)的两倍一样快
所以最后答案是C.
推荐练习:
Today, because of improvements in agricultural technology, the same amount of acreage produces double the apples that it has in 1910.
(A) double the apples that it has
(B) twice as many apples as it did
(C) as much as twice the apples it has
(D) two times as many apples as there were
(E) a doubling of the apples that it did
答案解析如下:
(A)【错误1】 比较结构:double不等于twice as many as,本选项double的语法不正确。
【错误2】 动词时态:has的时态与in 1910不搭配。
(B)【正确】 本选项正确使用了as(so)as的比较句式,补齐省略部分,比较结构应为the same amount of acreage produces twice as many apples as it(指代the same amount of acreage)produced apples(选项中省略为did) in 1910。
【大意】 如今,优于农业技术的'进步,同样公顷数产出的苹果是其1910年能够产出的苹果的两倍。
(C)【错误】 比较结构:不可数的much与apples不搭配。
(D)【错误】 比较结构:表达两倍应使用twice而不是two times,本题的比较结构属于比较句式,其本质应为发生省略后的两个平行可比的主谓结构之间相比,而本选项中半句there were(从前有(苹果))与the same amount of acreage produces(等公顷徒弟生产(苹果))并不平行可比。
(E)【错误】 简洁明了:在GMAT语法题中表达同一个意思时,简洁性从高到低依次为动词、形容词和副词、一般名词、动名词(简称VANing原则:Vverb,Aadj.或adv.,Nnoun,ing动名词),因此动名词的doubling相比(B)中形容词性的twice as many不具有简洁性。
【最优解题思路推荐】
(A)、(B)、(C)、(D)中仅有(B)正确使用了比较句式,形成了正确的比较结构,其他选项排除。
(E)的简洁性逊于(B),因此选择(B)。
