His brother likes history very much. He knows a lot about Chinese history, especially history of social development.

A. /; / ; the

B. / ; the ; /

C. the ; / ; /

D. the ; / ; the

答案：

(答案→)A. /; / ; the

B. / ; the ; /

C. the ; / ; /

D. the ; / ; the

解析：考查定冠词的用法。在学科前面一般不用定冠词，如chemistry, physics, history, geography等，第二空“中国历史”，是泛指，不是特指某段中国历史，因此也不用定冠词，第三个空history后面有of social development来修饰，因此是特指，要加定冠词。
