GMAT高頻詞彙twice用法實例講解

In the 1980’s the rate of increase of the minority population of the United States was nearly twice as fast as the 1970’s.

(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

選項分析:

A中是twice as fast as the 1970’s 在這裏是rate和1970's比較,是不對的,

DE都是錯誤搭配用法

然後看the rate of increase of the minority population of the United States

C選項的意思是:A的人口增長率是B的兩倍

B選項的意思是:A的人口增長率是B的(人口增長率)的兩倍一樣快

所以最後答案是C.

推薦練習:

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)【錯誤1】 比較結構:“double”不等於“twice as many as”,本選項“double”的語法不正確。

【錯誤2】 動詞時態:“has”的時態與“in 1910”不搭配。

(B)【正確】 本選項正確使用了“as(so)……as……”的比較句式,補齊省略部分,比較結構應爲“the same amount of acreage produces twice as many apples as it(指代‘the same amount of acreage’)produced apples(選項中省略爲‘did’) in 1910”。

【大意】 如今,優於農業技術的'進步,同樣公頃數產出的蘋果是其1910年能夠產出的蘋果的兩倍。

(C)【錯誤】 比較結構:不可數的“much”與“apples”不搭配。

(D)【錯誤】 比較結構:表達兩倍應使用“twice”而不是“two times”,本題的比較結構屬於比較句式,其本質應爲發生省略後的兩個平行可比的主謂結構之間相比,而本選項中半句“there were(從前有(蘋果))”與“the same amount of acreage produces(等公頃徒弟生產(蘋果))”並不平行可比。

(E)【錯誤】 簡潔明瞭:在GMAT語法題中表達同一個意思時,簡潔性從高到低依次爲動詞、形容詞和副詞、一般名詞、動名詞(簡稱VANing原則:V——verb,A——adj.或adv.,N——noun,ing——動名詞),因此動名詞的“doubling”相比(B)中形容詞性的“twice as many”不具有簡潔性。

【最優解題思路推薦】

(A)、(B)、(C)、(D)中僅有(B)正確使用了比較句式,形成了正確的比較結構,其他選項排除。

(E)的簡潔性遜於(B),因此選擇(B)。
