Question

【题目】Wars are disasters. A large number of people will lose their homes if a war _____________.

A. is broken out B. is broken up C. breaks up D. breaks out

Answer 1

【答案】D

【解析】

句意：战争是灾难，如果爆发战争，很多人会失去他们的家园。is broken out形式错误，break out爆发，不能用于被动语态；is broken up打碎，终止，是被动语态；breaks up终止，打碎；breaks out爆发。根据句意可知，战争应该是“爆发”，故应选D。
