在这里，明明是I，却和WERE连用；

注意后面是WOULD，而没有用WILL。

如果你想为Cobuild语料库捐款，请随订货单附上支票。

If only 是一种表示愿望的惯用说法,意思是“要是…那该多好”或“但愿…就好了”,因此前面的感叹句是虚拟语气,其中谓语动词用的是对过去虚拟的 could he ed,意思是“我要是当时若wish 后的宾语从句中用would，可以表示请求，通常意味着说话人的不快或不满。能帮你那该多好啊”.

marry

由于感叹句中的虚拟时态已经确定了时间的大前提是发生在过去,后面所说的“我真的不知道如何帮你”当然也是指过去的那个时间,因此要用过去时 had.

he had no good idea 指的是到现在也不知道,与上文所表示的时间没有关系.

ifonly和nexttime的区别

2. 在 insist 后的从句中, 如果是坚持自己, 用陈述语气, 坚持别人做什么事情, 用虚拟语气.

It seems as if it were spring already 似乎现在已经是春天的样子了。句式、用法。

1、nexttime的意思是下一次，句式为未来式，ifonly的意思是要是…就好了，句式是过去式。

2、nexttime是相对现在而言的“下一次”，用于直接引语中。i（3）从句表示与将来事实相反，谓语动词用“would／could／might＋动fonly主要用在虚拟语气中，用以表达强烈的愿望或非真实条件。

关于虚拟语气

7、以 lest, for fear that, in case 引出的从句，动词多用 should + 动词原形，表示 “惟恐”的意思。

虚拟语气是一种动词形式，表示说话人的一种愿望，设，怀疑，猜测， 建议等含义，虚拟语气所表示的含义不是客观存在的事实。在条件句中的应用，条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是设的或实际可能性不大的情况，故采用虚拟语气。

8、在 if only 引出的感叹句中

一、虚拟语气在从句中的使用

虚拟语气即表达不可能发生或与预期相反的情况。首先我们应熟悉它在三种时态里的使用情况，这是正确使用虚拟语气的基础。这三种时态是：现在；过去；将来。

1、表示现在的虚拟式

现 在 did would + do

If I were a bird, I would fly to you. 如果我是只鸟，我就会飞到你身边去。

If it were not for their , we should be in a very difficult ition.

如果不是他们的帮忙，我们就会处于一个非常困难的境地。

2、表示过去的虚拟式

过 去had + donewould + he + done

If we had started earlier, we should not he missed the train.

如果我们早一点动身的话，就不会误车了。

If she hadn’t been ill, she might he come.如果她不是病了，可能会来的

3、表示将来的虚拟式

将 来should + do

were to + dowould + do

If Professor Li should he time tomorrow, we could ask him some questions.

如果李明天有空的话，我们可以问他点问题。

If there should be no air, there would be no living things.

二、错综时间的虚拟句

通常情况下,在非真实条件句中主句和从句的谓语动词所指时间是一致的, 但有时也可能指不同的时间,这时要根据上下文的意思采用不同的谓语动词形式.

If I were you,/should I would he taken his a. (从句指现在, 主句指过去)。

换成我是你，我就会听从他的建议。

If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去,主句指现在)。如果我今天早上带了雨衣，现在就不会被淋湿了。

(从句指过去，主句指现在)。如果过去几年里不努力工作，现在的情况就不会如此顺利了。

If the weather had been more forable, the crops would be growing still better.(从句指过去，主句指现在)。如果当时的天气更好点，现在的庄稼就会长得更好。

If we had not got rything ready by now, we should be hing a more terrible time tomorrow. (从句指现在，主句指将来)

如果现在一切还没准备好，明天情况就更糟了。

三、含蓄条件句

有时设的情况并不以条件从句表示出来,二是暗含在上下文中,比如通过介词短语来表示。这些介词常是：but for, without, otherwis等。如：

如果不是听了你的建议，我就不会做的如此成功。

The change could not he taken place without the open-door policy.

没有开放的政策，就不会有如此大的变化。

I was so busy then, Otherwise, I would he told him the answer.

3、it is desired, it’s suggested, it’s requested, it was ordered that, it was proed that, it is necessary that, it is important that, it has been decided that 等之后的主语从句：

It’s required that Mr. Lee (should) give a performance at the party.

要求李先生在晚会上出个节目。

It’s desired that we (should) get rything ready by tonight.

要求我们在今晚前把一切准备好。

4、在suggestion, motion, proal, order, recommendations, plan, idea 等后面引出的表语从句和同位语从句中：

The order came that all villagers evacuate from the village.

要求所有村民撤退的命令下达了。

I second Xiao Li’s motion that we set up a special board to tackle the problem.

小李提议成立一个特别委员会处理此问题，我附议。

5、在下列句型中要用 should +动词原形。如：it is a pity, it is a shame, it is incredible, it is strange, it is no wonder

It is a great pity that he should be so conceited.

很可惜，他这个人竟然这么自大。

奇怪的是他竟看不到自己的缺点。

我清楚地记得这件事就象昨天刚刚发生的。

If only I hadn’t lost it! 如果我要不丢该多好！

现在该是结束这场争辩的时候了。

10、用于expect, beli, think, suspect 等动词的否定或疑问形式后的宾语从句中。

I nr expected that the new apartment should be so all. 没料到这桩新公寓竟这么小。 虚拟语气是一种动词形式，表示说话人的一种愿望，设，怀疑，猜测， 建议等含义，虚拟语气所表示的含义不是客观存在的事实。在条件句中的应用，条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是设的或实际可能性不大的情况，故采用虚拟语气。

wish和if only的虚拟语气

有谁能帮助我就好了！

if only 和wish 要表示将来的虚拟，要退一步

主句：主语＋would/should/might/could＋动词原形

用过去It is time that we went (should go) to bed. 现在该上床了。将来时

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

If only she would come! 但愿他能来

if only 和what if后面需要用虚拟语气么？

3. 如果将wish改成wished, 其后that 从句中动词的形式不变.

是需要用的。以if为例：①

虚拟现在时表示与现在事实相反的设，其if

从句的谓语形式用动词的过去式(be

一般用were)，主句用would/

should/

coul5、用在以as if (as though) 引出的方式状语从句中d/

might

+动词原形，例如：If

Iwere

in

your

ition

her.

②虚拟过去时是表示与过去事实相反的设，if

从句的谓语形式用过去完成时即had＋过去分词，主句用would

/could

/might

+he

it

had

not

rained

so

听老师之间的对话学习虚拟语气hard

yesterday

we

could

he

played

tennis.

③大多数的虚拟条件句属于上面三种情况的一种，但并不排除存在条件和后果中，一个和现在情况相反，另一个和过去情况相反，例如：If

you

had

followed

what

the

doctor

said,

you

would

not

he

been

so

painful

now.这个句子在高中出现频率颇高。

only if与ifonly区别?

1、提出将来会发生的事：主句：主语＋would/should/might/could＋动词原形；

only if 意思“仅仅如果”，用于条件状语从句，比if所表达的语气更强烈。置句首可引起倒装。

+过去分词，例如：If

if only 用于虚拟语气,表示“要是...就好了“。它用来表达一个不可能实现的愿望或设。

整个房间看起来好像是经过了多年的精心布置。

与过去事实相反,后面跟过去完成时，had+过去分词。

与现在事实相反,后面跟一般过去时。

与将来事实相反,后面跟一般过去时或should + 动词原形。

例句辨析：

only if

1、I'll do that, but only if we set a few rules.

我可以干，但我们得定几条规矩。

2、The placebo effect can be understood only if we acknowledge the unity of mind and body.

只有我们承认身心一体，安慰剂效果才能被理解。

3、The lawyer is paid only if he wins

4、You can make progress only if you are modest.

惟虚心乃能进步。

if only

1、If only it were that !

要是那么简单就好了！

2、If only someone could me!

3、If only I could get some sleep, I would be able to cope.

要是能睡上一会儿，我就能应付了。

4、If only I could be of this subject.

if only：要是……多好啊。常用虚拟语气

only if：除非，唯有

if only 用于虚拟语气,表示“要是...就好了”

If only one had an unlimited supply of money!

要是财源不断就好了!（与现在事实相反）

only if 意思“仅仅如果”,用于条件状语从句.

求大神回答 关于虚拟语气和 if only 如果不省略主句怎么弄

虚拟语气有很多情况，if的条件状语从句是非常常见的一种。你说的表格使用与if。与将来情况相反时，if从句里的should不能换成could/would等，错综混合虚拟语气结构仅适合if从句。if only后面不用想负责了，一般就两种情况居多。

6、as if, as though 引起的从句，其用法同 wish 构成的宾语从句一样I f only I were you.

与How I wish it wasn’t raining now. 如果现在不下雨该多好呀！现在情况相反，用一般过去时

If only I had been to Thailand last year

与过去情况相反，用I remember the whole thing as if it happened yesterday.过去完成时。

if only 这个写句子怎么应用 其他的倒装句解析 谢谢

I wish I knew his address.

你有邮箱吗？我发给你。

If we hadn’t been working hard in the past few years, things wouldn’t be going so oothly.

我的邮箱是：idoso@yahoo

楼上写这么多其实就是说if only 后面要倒装，only if后面不用，只是表示语气上的强调，并没回答你的问题。倒装就是说正常的句子把第二部分的谓语和第我多么希望能精通这门学科。三部分的表语掉一下以增强语气或使句子读起来比较拽。当然这只是最常见的倒装，部分和第三部分或第二部分也是可以倒桩的。

求if、only if 、as if虚拟语气的用法？

扩展资料

虚拟语气用法：

1、用在含蓄条件句中

句子中，设的情况不用条件从句表示出来，而是用一个介词短语来表示，句子的谓语形式也可遵循上表的规则。

这种用法也常见于or, or else, otherwise和but后面的分句中。

例如：Without music, the world would be a dull place.

2、用在错综时间条件句中

有时候，条件从句表示的动作和主句表示的动作发生的时间并不一致，这时，谓语动词的形式要根据表示的时间来调整，这种句子可称作错综时间条件句。例如：

If you hadn’t watched evision so late, you wouldn’t be so sleepy now.

此句为时间交错的虚拟条件句，从句表示与过去事实相反的设，主句则设与现在情况相反

3、用在wish后的宾语从句中

这种句子主要表示愿望，that常省略。若指现在或将来的愿望，从句用过去时;若指过去没有实现的愿望，从句用过去完成时。

例如：I wish I had learned to play chess.(与过去事实相反)

例如：I wish you would us.

4、用在if only感叹句中

例如：If only I knew what you wanted.

当表示过去想象中的动作或情况时，用过去完成时;当表示和现在事实相反或对现在情况有所怀疑时，用一般过去时。

例如：Th如果你进了城，你会注意到所有的酒吧都有音量很大的自动点唱机。e old couple loved the orphan girl as if she had been their daughter.

6、用在某些虚拟的定语从句中

He was the very person I should he been wished to see.

7、用以表示说话人的主观愿望或选择，仅用在一些惯用句型的从句中

I’d rather they came tomorrow.

但had rather, would rather, would just as soon, would sooner等惯用语如用在简单句中，其后都用不加to的动词不定式。

例如：I’d rather die than give up my principle.

从句：should＋动词原形/were to＋动词原形；

2、提出现在的条件： 主句：主语＋would/should/might/could＋动词原形；

从句：动词过去式；

例句：If he studied at this school, he would know the enviornment around the school very much.

3、提出过去的未发生的条件：主句：主语＋would/should/might/could he＋动词过去分词

从句：had＋动词过去分词

例句： If I had read the book, I would he told you about it.

扩展资料：

与现在事实相反：If I were you, I would go there tomorrow.

与现在事实相反：If he came to the party, I wouldn't come.

与过去事实相反：If she had been there, she would he met Jack.

与将来事实相反：If it were to rain tomorrow, they couldn't go for an outing.

与将来事实相反：If they should attend the meeting, we might get more support from them.
