一、真实条件句

可用if引导,具体有以下三种情况:

3. will用于if从句中,不表示将来,而表示愿意或坚持。例如:

一、wish用法说明

动词wish后接宾语从句时，从句谓语要用虚拟语气。

要表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时（be 动词一律用were）； 表示与过去相反的愿望，从句谓语用过去完成时或would/could+had +过去分词；

表示将来没有把握或不太可能实现的愿望，从句谓语用would/could/should/might＋动词原形。I wish I were not so busy.但愿我不那样忙碌。

I wish I were [was] better looking.要是我长得漂亮些就好了。

She wished she had stayed at home.她后悔的是她当时要是留在家里就好了。

I wish you would go with us tomorrow.要是你明天同我们一起去就好了。

I wish you wouldn’t look down on this kind of work.我希望你不要看不起这种工作。

This watch has gone wrong.I wish I had bought a better make.这只表坏了，我真愿意我买的是好一点的牌子。

I wish you wouldn’t smoke any more.我希望你不再抽烟了。

I wish you would be more respectful to your father.我希望你对你父亲更尊敬些。

I wish I could be of some use.我希望我能有什么用处。

二、if only

1.在if only这个短语中，only只是加强if的语气的，不仅能表达说话人的愿望，而且能表达条件。If only they were here now, we would be able to celebrate their wedding anniversary.如果他们现在在这里，我们就能庆祝他们的结婚纪念日了。

2.if only常常用来表达强烈的愿望或遗憾，主要用在虚拟语气中，用以表达强烈的愿望或非真实条件。意为“但愿”、“要是„„该多好啊”等。

If only she could have lived a little longer.要是她能活得再长一些，那该多好啊！

3.if only有时也可以写成if...only。If she would only come!但愿他能来。

三、only if

1.only if 引起的条件状语从句，表示“只有„„(才)；只有在„„的时候；唯一的条件是„„”的意思，当only if 引导的状语从句置于主句之前时，主句要用倒装语序。

Only if the case is urgent should you call out the doctor in the middle of the night.只有患者情况紧急时，你才可以在半夜叫医生看病。

Only if a teacher has given permission is a student allowed to enter this room.只有得到教师的允许，学生才可以进这间屋。

虚拟语气实在讲 第4篇

If you were more friendly to people, you would have more friends.

如果你对人更加友好，你会有更多的朋友。

If I were you, I would accept his gift.

如果我是你，我会接受他的礼物。

虚拟语气主要用在非真实条件句（if从句）中，经常用于条件从句和结果从句中。在表示与事实相反的虚拟语气时，动词有3种时态，即现在时、过去时和将来时。

A．与现在事实相反

If I were you, I'd take an umbrella.

如果我是你，我就会带一把伞。（事实上，我不可能是你。）

If there were no air or water, there would be no living things on the earth.

如果没有空气和水，地球上就不会有生物。（事实上，地球上既有空气又有水。）

例题：

1.If I you, I'd wear a shirt and tie.

A. am B. wasC. were

2.If I were rich, Ianything you wanted.

A. will buyB. would buy C. buy D. would to buy

解析：这是两个假设的非真实句子，习惯上动词要用过去时。If I were you(假如是我)已成为一个固定用语，故答案为C和B。

B．与过去事实相反

If I had got there earlier, I should(could) have met her.

如果我早点到那儿，我就会见到他。（事实上，我去晚了。）

If I had been old enough at that time, I would have gone to school.

如果那时我够年龄的话，我就上学了。（事实上，我那时年龄小。）

例题：

3.If I had had enough time, I my work.

A. would finishB. must have finished

C. would have finishedD. had finished

4.If I had seen the movie, I you all about it now.

A. would tell B. will tell

C. have toldD. would have told

解析：上面两题都表示与过去事实相反，所以答案为C和D。

C. 对将来情况的主观推测（表示可能相反或可能性很小）

If he would come here tomorrow, I should(would) take to him.

如果他明天来这儿的话，我就跟他谈谈。（事实上，他明天来的可能性很小。）

If there were a heavy snow next Sunday, we would not go skating.

如果下周日下大雪，我们就不能去滑冰了。（事实上，下大雪的可能性很小。）

If he were to do it, he would do it better.

如果他去做这事，会做得更好。（事实上，他去做这事的可能性很小 / 他根本不会去做这事。）

例题：

5.If I won the lottery, Ithe money to medical research.

A. will giveB. would giveC. gave

解析：此题表示与现在事实相反的主观设想，也可以表示在说话人看来实现的可能性很小的将来时。所以答案为B。

虚拟语气的其他用法

1.表示与现在事实相反的愿望，谓语动词用过去时。例如：

I wish I had your brains.

我希望我能有你那样的头脑。（事实上，我根本比不上你。）

2.表示与过去事实相反的愿望，谓语动词用“had + 过去分词”的形式。例如：

I wish I had known the truth of the matter.

3.表示将来难以实现的愿望，谓语动词用“should(would) + 动词原形”的形式。例如：

I wish I should have a chance again.

我真希望能再有一次这样的机会。（事实上，很难再有这样的机会。）
