问题补充：

My uncle’s house in the downtown area is much smaller than ours , but it is twice expensive .

A. as

B. so

C. too

D. very

答案：

(答案→)A. as

B. so

C. too

D. very

解析：本题考查倍数的表达：倍数+as. . . as. . . 结构。句意为：我叔叔在闹市区的房子比我们（不在闹市）的房子要小得多，但是它的价格却是我们的房子价格的两倍。it is twice as expensive后面省略了as ours，所以选A。
