问题 Scientists involving in a serious debate about how to solve the problem of global warming.

选项 A、were to involve in
B、involved in
C、were involved in
D、were to be involved in

答案 C

解析 本题重点考查被动语态的用法。画线部分用的是现在分词词组,现在分词表示“主动,进行中”,但本句的意思不是科学家主动参与辩论,而是被迫卷入这场辩论,应该使用被动式才对。四个选项中,C和D都是被动式,是可能选项。D表示过去将来,从时间上看不正确,故选C,表示“已经卷入了”。
