问题补充：
The house rent is high. Ive got about half the space I had at home and Im paying here.
A. three times much as
B. as much three times
C. much as three times
D. three times as much
答案：
A. three times much as
B. as much three times
C. much as three times
(答案→)D. three times as much
解析：考查倍数。此题考查倍数与省略，三倍可表达为.three times as much as，而本句省略了as。当说话人和听者明白比较的对象是什么时第二个as 可省。句意：这所房子房租太贵了，这房子的面积是我家里的房子一半大小可我却要为它付（我家里的房子的）3倍的价钱。故D正确。
