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”。
