if+一般过去时,主句would/could+动词原形表示与现在事实相反if it rained tomorrow,we would stay at home.这个是将来我怎么知道与事实相反呢 If the train leaves at half past ten,there ____ no time to lose.A.would B.is C.will D.has为什么不是 there will be if 条件状语从句，主句用将来时，从句用一般过去时表将来。 if引导的条件状语从句中,主句一般过去时,从句用什么时态? as if引导方式状语从句,主句有一般现在时,从句用一般过去时, if only the rain would stop.用would是什么用法?if从句不是不用would的吗?主句才用would啊! after+过去完成时(从句)+(主句)一般过去时怎么造句? (主句)过去完成时+before+一般过去时(从句)怎样造句? if it___tomorrow,i'll stay at home.A.rainedB.will rainC.hd rainedD.rains我判断这个是对将来的虚拟 但是根据虚拟条件句用谓语:/一般过去时/should/were to+动词原形 主句用谓语:would/should/could/might +动词原形 不 if 虚拟条件句的问题, 从句had done ,主句不是应该would have done么? If he were here,he would help me now.If he asked me,I would go with him.请问以上句子主句各是什么时态,为什么? If you had come earlier, you would have met him. 后半句不要have可以吗为什么要would have,不可以主句是would表示对将来虚拟 if宾语从句主句时态 if引导从句还是主句 since+从句用一般过去时,+主句用现在完成时是什么意思 主句一般过去时,after后跟什么时态?坐等,谢谢~ would it be nice if it were spring all round.would it be nice 在这里是 什么倒装?虚拟时主句可以倒装吗不是疑问句 what would you do if you saw the traffic accident ,不是主将从现么if引导的条件状语从句虚拟语气的时候,主句什么时态 If I were you ,I would go at once如果不分什么是主句 什么是从句那If I were you是虚拟状语吗
