【题目】Jack Smith earns ______his wife Jane while they do the same amount of work, which is unfair.
A.twice as many asB.as twice much as
C.twice more money asD.twice as much as
在线课程【答案】D
【解析】
考查倍数表达法。句意：杰克·史密斯挣的钱是他妻子简的两倍，而他们的工作量相同，这是不公平的。表达倍数时可套用句型“……倍数+as+形容词（或 much）或副词原级+as”，earn后省略了宾语money，因其为不可数，故用much，可排除A项，故答案为D。
