题目内容
7.Since 1949,the people's living standard _______,causing a big _______ in population.( )A. | has been raised; rise | B. | has been rose; raise | ||
C. | has raised; rise | D. | has raised; rose |
分析 自从1949年,人们的生活水平得到了提高,引起了人口的极大增长.
解答 答案:A.raise作及物动词,为"提高,提升"之意,rise为不及物动词,无被动语态,人们的生活水平和提升之间是被动关系,故使用raise的被动语态,而since 1949表明主句需要使用现在完成时,第一空应为has been raised,而第二空rise可作名词,故选A.
点评 本题考查现在完成时的被动语态.需要学生从语态和时态两方面分析动词的适当形式.
