A. free; is set free
B. freely; was set free
C. freely; is set free
D. free; was set free
答案：
A. free; is set free
B. freely; was set free
C. freely; is set free
(答案→)D. free; was set free
解析：考查free的短语。形容词free自由的，免费的；副词freely自由地，随意地；本题的be后面要接形容词，构成系表结构；固定词组set free释放；句意：战争的罪犯希望能够自由，十年以后，他能够被释放并回家。根据句意说明第二空应该使用被动语态的形式。故D正确。
