Question

As Susan stared at ______ piles of plastic in her recycling bin, ______ strong sense of responsibility made her stick to her recycling work.

A．不填；不填

B．不填; a

C．the ; a

D．the; the

Answer 1

C

解析試題分析：句意：當(dāng)蘇珊盯著垃圾箱里許多的塑料時(shí)，一種強(qiáng)烈的責(zé)任感使她堅(jiān)持下了她的回收工作。由句意可知，題干中第一空表特指，需用定冠詞the,第二空是泛指，所以用a。故C正確。
考點(diǎn): 考查冠詞的用法。
