To clarify the circumstances requires more effective measures than __ A.have been supposed B.has
than 引导的什么从句?在句子中做什么成分?老师说被动句中省略了it ,为什么要省略?
than 引导的是一个比较状语从句,如果状语从句中的主语和主句中的主语一致.在状语从句中常可省略主语或主语加系动词.
这句话说完全了,就是It requires more effective measures to clarify the circumstances than it have been supposed .
