问:虚拟语气里的混合时态,iF+过去式…woulD hAvE ...

比如如果当初他听了建议,他现在就不会有麻烦了.If he had listened to the advice,he wouldn't be in trouble now.他没有听从建议是过去的事情,所以从句用过去完成时表过去虚拟,而后面的主句是针对现在的情况,只用过去时wouldn't,事实上他现在有...

Please tell me if you would take him along, If take him come along, I'll put this news to Jimmy (真实条件句,用法,主将从现) If I hadn't met him yesterday,I wouldn't come here now. 从句与过去事实相反,主句与现在事实相反.

对,但不全

1. 表示与现在事实相反的情况,其句型为“ if+ 主语 + 动词的过去式( be 动词用 were ),主语 +would / could / might / should + 动词原形”。如: If the weather were fine, we would go to Shanghai. 如果天气好,我们就去上海。(事实上天...

第一步:掌握对现在,对过去,对将来的虚拟的固定时态 对现在的虚拟: If he were free, he would help us. 要是他有空的话,它会帮助我们的。 注意,虚拟中的is,都用were 注意,主句用would +动词原型,从句用过去式 对过去的虚拟 If I had see...
