A. a…a　　　 B. the…the　　　 　C. a…the　　　 D. the…a

答案为C。

[解析] 注意序数词前面的冠词的用法：当序数词表示顺序时用定冠词the；表示再来一次使用不定冠词a (an)。从句子的意思可知，third one表示再吃一个，所以填a；second one表示所吃的第二个，所以填the。这句话的意思是：蛋糕很好吃。他想再吃一个，因为他吃的第二个太小了。

例7、________ of the land in that district　 ________covered with trees and grass.

A. Two fifth...is　　 B. Two fifth...are　 C. Two fifths...is　 D. Two fifths...are
