介绍一下虚拟语气拜托各位大神(*^__^*)...嘻嘻
虚拟语气 主要从大的来说可以分为三类． １.表示与现在事实相反的,非真实条件句用（动词的过去时ＢＥ的过去时ＷＥＲＥ）,主句（would ,should ,could ,might）+动词原形 例句,If I WERE you ,I WOULD consider their plan.2.表示和过去事实相反,非真实条件句（had +动词过去分词）,主句（would ,should ,might ,could +have +done ）也就是主句现在完成时,从句过去完成时． 例句,If I HAD SEEN you yesterday ,I WOULD HAVE ASKED you about it .3.表示和将来事实相反的,非真实条件句（should ＋动词原形/were to 动词原形/动词过去时）,主句(should ,could ,might ,would +动词原形) 例句,If it SHOULD rain ,the corps WOULD be saved.还有几类也应该注意的,也是比较常考的． if only ,would rather ,had rather ,it's (high)time ,as if /as though 这五类,主句如果是一般时,从句用did,主句为过去时是,从句had done ,主句为将来时,从句would do .从句中主要是动词变化． 系动词were ,住动词had ,should等词,可以把were ,should,had 放句首,这时可以省略if.eg.were I you ,I would get up early .还有一些动词．suggest ,demand ,order insist ,request ,desire ,propose ,等词修饰的时候,谓语动词用should +动词原形． eg,I suggested that we should form a spare time study group.这中情况,it'snecessary ,important ,strange ,suggested ,ordered ,proposed ,request,decided ,a pity.+主语从句,谓语动词要用,should +do /should +have done
