10 The air inside a house or office building often has higher concentrations of contaminants _____ heavily polluted outside air.

(A) than does

(B) more

(C) as some that are

(D) like of

答案：A.

分析：有higher比较级必有than，故直接可以选出A选项。Than后面引导倒装句，句尾省略动词have，即“…than does……have。”

C选项中的as在表示作比较的时候通常是成对出现的。

翻译参考：在房屋或办公楼里的空气比起外面严重污染的空气有更高的污染浓度。
