As a teacher,you should not ________ the students from asking questions in class. A.refrain B.restrain C.forbid D .prevent 答案选B，ABCD怎么区分啊，不都有阻止某人做某事的意思吗？

Answer 1

这些动词均含“阻止、抑制、制止”之意。
restrain → 含义广，指用强力或权力去阻止或限制某人做某事。
prevent → 含义广泛，指采取预防措施或设置障碍去阻止某人或某事
refrain → 常指暂时对某种行动或冲动的抑制。一般用作不及物动词
forbid → 明令禁止

从结构上看,除了refrain, 其它三个都行!
