请大家帮分析这句子,it was impossible 在这里做什么成分,怎么理解呢?when 做什么成分?
it was impossible for the Ombudsman to take action,but when he received a similar complaint from another foreigner in the same village,he immediately sent one of his lawyers to investigate the matter
it was impossible 是it is +形容词+to do的固定形式,是形式主语,真正的主语是to do,即to take action;
when 引导的是时间状语从句,主句是 he immediately sent one of his lawyers to investigate the matter
这些都是固定用法,熟悉各种状语从句很容易就能看出来了
