(单选题)

Four and half hours of discussion took us up to midnight, and break for cheese, chocolate and tea with sugar.

A.a; a

B.the; the

C.不填; the

D.a; 不填

参考答案：A

参考解析：

考查不定冠词。句意：四个半小时的讨论一直持续到半夜，我们休息了一下，吃点奶酪、巧克力和含糖的茶。四个半个小时的表达方法常见的有两个：（1）four hours and a half；（2）four and a half hours。两种方法都要用到不定冠词a，排除选项B和C；break作名词，当“休息”讲的时候，通常都要用到不定冠词a，表示“休息一下”，排除选项C。故选A。
