LZM第二题 overextend的主动vs.被动

Jagabee

F-2 The speculative fever of the Roaring Twenties infected rich and poor alike; great numbers of people were dangerously overextended, credit was absurdly easy to obtain, and most brokerage houses required only ten percent cash for stocks bouth on margin. （正确答案）


这道题是考可数和不可数名词，但是我不能理解为什么这里的overextend要用被动语态. 一般overextend的用法，字典是："he should not overextend himself on the mortgage"

Speculative fever 定义：a term used in the housing market which represents the frequent action of buying and selling housing properties

这里原题难道是想说是speculative fever导致人们被dangerously overextended? 我怎么感觉是infect了之后人们自己overextend的选择, 应该为’great numbers of people dangerously overextended themselves?"

被动句补完:great numbers of people were dangerously overextended by the speculative fever of the Roaring Twenties
主动句：the speculative fever of the Roaring Twenties overextended great numbers of people

理解上有问题吗？

应该是理解有问题才错的吧...

我是看到‘；’  想到这个符号前后是两个语义有关联但是语法独立的结构 主语是拿great number of ppl 来考虑的， the speculative fever 像infection一样就是种影响

感觉这个坑好难避啊 最后两个个部分平行也并不都是用被动语气
