问题补充：

We for cheap houses but haven’t found we like yet.

A. are looking；one

B. have looked；it

C. have been looking；one

D. looked；them

答案：

A. are looking；one

B. have looked；it

(答案→)C. have been looking；one

D. looked；them

解析：

句意为：我们一直在找便宜房子，但是(到现在)仍未找到我们喜欢的(一所房子)。根据语境可知，找房子这一动作一直在进行，所以用现在完成进行时指过去开始的动作一直持续到现在；第二空one指代“a＋前面提到的名词”，即a house。
