问题补充:
Once air pollution in most cities, it is hard .
A. rises; dealing with
B. arouses; to be dealt with
C. raises; dealt with
D. arises; to deal with
答案:
A. rises; dealing with
B. arouses; to be dealt with
C. raises; dealt with
(答案→)D. arises; to deal with
解析:考查动词辨析和不定式的用法:句意:在多数城市一旦空气污染产生了,就很难解决。Rise是“上升,上涨,起身”,arouse“激起”,raise“提高,筹集,饲养”,arise“产生,发生”,所以第一空填arise,第二空使用的是:Sb/sth is +adj +to do…句型,其中的不定式用主动表示被动,选D。
