—Do you know when Britain war on Germany during the Second World War?

—In 1993，I suppose.

A. announced

B. declared

C. fought

D. attended

答案：

A. announced

(答案→)B. declared

C. fought

D. attended

解析：CD选项词义不符提议，declare 经常用于正式场合,指“清楚, 有力地, 公开让人知道”, announce 指“把人们关心或感兴趣的事正式公布于众”，宣战应该是很正式的事情，所以选B。
