问题选择题

—How about ____ controlled breeding programme the US government began to save the red wolf?

—I should say it was ____ success, you see its number has increased

A．a ; a

B．the; a

C．a;不填

D．the ; 不填

答案

答案：B

题目分析：考查冠词的用法。a/an表示泛指，意为“一个，某个”；the表示特指，意为“那个，这个”。success成功，不可数，但指“一件成功的事或一个成功的人”时，是可数名词，用a修饰，排除C、D；the+done/doing+名词，特指“那个......”。故选B。
