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..
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
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.
第一句是:如果她以前能更努力工作,它就能成功
意思是说她以前不努力,这会没成功
第二句:如果昨天问过他,今天你就知道怎么做了,
这两句是时态的差别,句意上没什么区别
第一句用的全部是虚拟,但是混合条件句就不是了,you would know what to do now用的不一定是虚拟,也有可能应该用什么时态就用什么时态
例如:
I could have come the party yesterday,but i was busy then.
虚拟的用法还是要弄熟的哦
