问题补充：
Her husband earns she while they do the same amount of work.
A. twice as many as
B. as twice much as
C. twice more money as
D. twice as much money as
答案：
A. twice as many as
B. as twice much as
C. twice more money as
(答案→)D. twice as much money as
解析：考查倍数的表达。倍数应放在最前面，此题考查的结构为：倍数+ as … as ，句意：当他们做同样数量的工作的时候，他的丈夫挣得钱是她的两倍。许多钱应用much money，money不用many修饰，所以选D。
