补充题101. The speculative fever of the Roaring Twenties infected rich and poor alike; vast quantities of people were dangerously overextended, credit was absurdly easy to obtain, and most brokerage houses required only ten percent cash for stocks bought on “margin.”(P2 F-2)

(A) rich and poor alike; vast quantities of people were dangerously overextended

(B) both rich and poor alike; large amounts of people dangerously overextended themselves

(C) rich and poor alike; great numbers of people were dangerously overextended

(D) both rich and poor alike; vast amounts of people dangerously overextended themselves（C）

(E) both rich and poor; great quantities of people were dangerously overextended

1.quantities of 只修饰不可数名词吗?那a quantity of 呢?

2.both rich and poor alike是什么用法?

a quantity of/quantities of后既可接复数可数名词，亦可接不可数名词

both rich and poor alike 是重复，both rich and poor; rich and poor alike都对，both 和alike 有重复之意

amount修饰people错，B D错

我个人认为A C E的表达都是正确的

这题你好像把 C里面的 themselves漏掉了吧？是根据themselves来得到正确答案C的

刘振民的书上说，quantities of + 可数名词是错的；这个我不同意，谁说不可以了？

以上是我的理解，open to discuss
