新prep sc1--181

实在不知道到哪里去下找新prep的讨论帖，只能跑来开贴，，

181.
                        (27438-!-item-!-188;#058&002362)

The number of people flying first class on domestic flights rose sharply in 1990, doubling the increase of the previous year. 

A. doubling the increase of

B. doubling that of the increase in

C. double as much as the increase of

D. twice as many as the increase in

E. twice as many as the increase of

那位给讲讲？我选的B

A. doubling the increase of

B. doubling that of the increase in   that没有指代

C. double as much as the increase of  double+noun；数字能用much修饰吗？问

D. twice as many as the increase in   many错

E. twice as many as the increase of  many错

我认为that是有指代的，它指代number, number of the increase 造成语义重复。

更正以上说法。

that在本句中是没有一个确切的词来指代的，因为后一句doubling...是做状语修饰主句表结果的。

在想后面是不是一个完整结构的省略：

doubling the increase of
                    people flying first class on domestic flights in the previous year

版主能解释下是不是这个结构么？

我查了一下longman中increase作名词是的用法，increase in是一个固定搭配

increase in
an increase in the crime rate
Recent tax increases have affected the poor more than the rich. the dramatic increase in the population aged over 65 There has been a marked increase in the use of firearms.Cases of tuberculosis are on the increase .

所以会不会是doubling the increase in
        the number of people flying first class on domestic flights of the previous year啊？

可是还有个很严重的问题，有of the previous year这种用法么？？
