谁可以帮我把高中英语的虚拟语气详细得讲给我听

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.下面给你弄几个习题,自己做,答案给你放最后,１.did you remind him of the meeting no ,if I __home ,I would have .A,was B,had been C,were D should be 2.do you have a theatre ticket for tonight?no ,but i wish i ____ A ,CAN B ,WILL C,DID D,HAVE 3.___enough money ,we could have done it much better.A,give B,to give C,giving D,given 4.___yesterday,i would have asked him not to do that .A ,had he come B,if he came C,did he come D,has he come 5.___better care of ,the trees would have grown better.A,to be taken ,B ,if you took C,had the trees taken D,taken 6.my sugestion is that a few more doctors ____to the mountain areas.A,be sent B,have sent C ,sent D,shoud send.7.when a pencil is partly in a glass of water ,it looks as if it ____.A,breaks B,has broken C,were broken D,had been broken.就给你弄这么多了,手酸,答案,ＢＣＤＡＤＡＣ 有什么问题加我ＱＱ,我直接和你说． 对了,一般should用与第一人称,would用于第三人称． 你这几道题答案,ＣＡＡＣＢ第二题有点拿不准．
