这两句子有什么区别?虚拟语气
1,表示于过去事实相反的假设.
句型：条件从句 主句
过去完成时 should(would) have+ 过去分词
A If she had worked harder,she would have succeeded.
2,混合条件句
主句与从句的动作发生在不同的时间,这时主,从句谓语动词的虚拟语气形式因时间不同而不同,这叫做混合条件句.
B If you had asked him yesterday,you would know what to do now.
我理解不了..好像都一样啊..

解答
A If she had worked harder, she would have succeeded. 都是过去的假设.
B If you had asked him yesterday, you would know what to do now.
前面是假设过去,意思是如果你昨天问我,
后面是假设现在,意思是现在你就会知道做什么了.
