第十三单元 第三课【语法点拨】
虚拟条件句
▶ 真实条件句和非真实条件句
▪ 英语中有两种条件句：真实条件句和非真实条件句。真实条件句表示提
出的假设是完全可以实现的，因此句子的谓语用陈述语气。非真实条件
句又称虚拟条件句，表示所提的假设与事实相反或实现的可能性极小，
所以句子的谓语动词用虚拟语气。
• If he doesn’t hurry up, he will miss the bus.
如果他不快点，他将错过这班公共汽车。(真实)
• If it rains tomorrow, I will stay at home.
如果明天下雨，我就呆在家里。(真实)
• If I knew her mobile telephone number, I could ring her up.
要是我知道她的手机号码，我就可以给她打电话了。(可惜我不知道)
• If I were a bird, I would fly to the south in winter.
如果我是一只鸟，我冬天就飞往南方。(不可能实现的愿望)
▶ 虚拟条件句的形式
▪ 现将虚拟语气条件句的三种形式列表如下
从句（条件句） 主句（结果句）
与现在事实相反的 （1） 动词过去式 should/would/could/might
假设 （2） be一律用were +动词原形
与过去事实相反的 had+过去分词 should/would/could/might
假设 +have+过去分词
与将来事实相反的 （1） 动词过去式 should/would/could/might
假设或实现的可能 （2） should+动词原形
性很小 形
（3） were to+动词原形
形
▶ 虚拟条件句的用法
▪ 表示与现在实事相反的假设。
• If there were no air or water, there would be no living things on the earth.
如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气
也有水)
• If I had any money with me, I could lend you some.
如果我带钱了，我就会借你一些。(事实：没带钱)
• If I had time, I would certainly go to the cinema with you.
如果我有时间，我一定陪你去看电影。(事实：没有时间)
▪ 表示与过去事实相反的假设
• If her mother had taken the doctor’s advice, she would/might have got
well earlier.
如果她母亲当时遵照医嘱，她本来/可能会早点康复的。(可惜她没
有遵照医嘱)
• I could have done better if I had been more careful.
我当时要是小心些，我本来会做得更好。(后悔当时没有小心)
• If you had come ten minutes earlier, you would have seen the film
actress.
你要是早来10分钟，你就能见到那位电影女明星了。(来迟了没见到)
• If I had left sooner, I would have been on time.
要是我早点动身，我就准时到了。(但我动身太迟了)
• If we had found him earlier, we could have saved his life.
要是我们当时早点找到他的话，我们就可以救活他。(可惜找到他太
晚了，没有救活他)
▪ 表示与将来事实相反的假设或发生的可能性极小。
• If it rained tomorrow, the sports meet would be put off.
要是明天下雨，运动会就推迟。(明天下雨可能性很小)
• If it were to rain tomorrow, the match would be canceled.
倘若明天下雨，比赛将被取消。(明天下雨可能性极小)
• If it should rain, the crops would be saved.
要是有雨，这些庄稼还有救。(下雨可能性很小)
• If you should miss the train, what would you do?
你要是误了那班列车，你怎么办?(误车可能性很小)
注:①主句谓语中的 should主要用于第一人称 would, might, could的区别大致是:
would表示结果, might表示可能性, could表示能力、允许或可能性。
试比较:
• If you tried again, you would succeed.
如果你再试一试，你就会成功的。(would表示结果)
• If you tried again, you might succeed.
如果你再试一试，你可能会成功的。(might表示可能)
• If you tried again, you could succeed.
如果你再试一试，你就能成功了。(could表示能力)
②条件从句中的谓语动词为be时，不论其主语为单数还是复数，通常都用
were，但在口语或非正式文体中，单数第一人称和第三人称后也可用was，不过
在 If I were you这样的习惯表达中，只能用were。
③有时would条件从句用表示愿意。
• I could do so if I would.要是我愿意，我能够这样做。(但我不愿意)
④ 当 条 件 从 句 使 用 “should+ 动 词 原 形 ” 时 ， 主 句 除 可 用
“should/would/could/might+动词原形”这样的虚拟语气外，也可用陈述语气或祈
使语气。
• If it should rain tomorrow, don’t expect me.
万一明天下雨，就不要等我了。
• If I should see him, I’ll tell him.
万一我见到他，我就告诉他。
