虚拟语气中should+动词原形与直接用过去式两种情况可否互换

这问题问得很好,这两句是有区别的,而且有很明显的区别.
第一句（虚拟语气）,说话的人很可能最终没有办法来帮你,因为他（她）可能很忙,基本上没有来的可能.
第二句（没有虚拟语气）,说话的人有可能最终可以来帮你,但目前他（她）对自己的时间安排不确定,不能保证地肯定地现在就给你一个确实的答复.

第一,“虚拟语气,若主从句主语一致,且谓语部分包含有动词be,通常可将主语和动词be省略”其实,这个不仅仅局限于虚拟从句和由if引导的条件状语从句,还有有很多状语从句（非虚拟语气）也适合.比如：I'll also provide a...

A-Hi,Tom
B-Hi,Jack
A-You look unhappy.What's up?
B-I failed the English exam again.
A-I'm sorry to hear that.Was it very difficult?
B-No,but I made many mistakes in listening.That's why I failed.
A.Don't worry,Tom.If I were you,I'd like do some listeng everyday.
B.Thanks,Jack.I'll try.But what if I practise listening with my classmates?
A.Good idea too.
B.Thanks,bye
A.Bye

demand是要求的意思,就是说她要求他把借来的书还给他.要求谁做什么事一般是有劝诫的含义,表示应该怎样,有should的意思在,所以一般是demand that somebody should do something...因为should是内涵的含义,不一定都要把应该这个词表达出来,所以should可以省略,那么should作为情态动词下面要加动词原形,所以是return不能加ed

1.had know （从句动作先于主句动作,用过去完成时）
2.(i) hadn’t done
3.wouldn't
4.should be held ( Insist 表示"坚决要求"时,用虚拟形式,即 should + do)
5.should be heard
额 这是我的见解 你再看下吧~

1 would get
2 rains

it's essential 后面可以接虚拟语气么
it is +essential等形容词后,that主语从句中虚拟形式使用,
这类形容词有：necessary, important, essential, imperative, urgent, preferable, vital, advisable 等,
如:
It is essential that you be able to pronounce every single word correctly.
又如：
It is necessary that you listen to the teacher carefully.

选B.
insist作坚持要求的意思时,从句才用虚拟语气,而作坚持的意思时,从句用陈述语气,所以选B.
这道题考得比较细,一般情况下不会这样考,记住insist这个词较为特殊的用法就行了.

虚拟语气,表示推测将来情况时,
主句：主语+should/would/could/might+do ,这个没疑问；
条件从句：
1,表示“是某种状态”,有二种句式：
(1),If sb were;
(2),If sb were to be;
2,同样表示“做某事”,百度百科列了三种句式,都是将来时态；
(1)If sb were to do;
(2)If sb should do；
(3)If sb did;
请问：以上
1的二种情况；
和2的三种情况；
是一样的,还是不一样?
如果不一样,如何不一样,使用上的区别?
不是问1和2之间的区别。
是问1里面，同样是表示“某种状态”，were to be 和were的区别；且二者同为虚拟语气将来时态；
2里面，同样表示“做某事”，should do和did和were to do三者什么区别？且三者同为将来时态；
以上，在百度百科里，

可以用过去将来，也可以用一般将来，这要看这个想法是在什么时候萌发的

在虚拟语气中,主语是将来时,从句是现在时,主语是过去时,从句就是过去完成时.分析几个句子中的谓语动词就能体会到.

英语如同其他语言一样,“约定俗成”是非常重要的.
你提到的“but for you”,实质上是 “if you had not helped me,”的简略表达型式,所以后面必然要接“I would have lost my way”.
同样在你的句子中,“but for mobile phone”表达的是类似“if mobile had not be used（developed）”的意思.后面接“……would not have been……”那是很自然的了.
对于这种（类）句型熟记就成了.
再补充一句,句中的“efficient”不可以用“fast”代替,“fast”（快速）仅是“efficient”（高效率——那么有效）的一个要素,而不能包括其他优异特点.

C
虚拟

advise sb to sth. 这里的sb应该用宾格，所以可以说advise him to give up smoking.

1 knew
2 should give
3 to be oberserved
4 discuss
5 to be cleaned
6 could speak

不可以省略

这个句子自然吗?some emphases还是emphasis（单数）更好?and 后面可以省略should吗?
Answer:句子没有问题
全句句构:主谓宾(宾语是由that引导的宾语从句来充当)
---"that"在从句中不作任何成分,也无任何意义,只起引导从句的作用.
----宾语从句的句构如下:
It(形式主语)is(系动词)imperative(表语)that some emphases should be laid on multiculture and several practical steps be taken.(主语)
因为"imperative"是表"需求/命令"的形容词作表语,故主句用了虚拟语气,谓语形式
should +动词原形 ,其中should可以省略
(2)some emphases 一些重点 ,several practical steps 各种实际措施
从并列主语对称的角度考虑,用"some emphases"更合适
(3) 此问题已在(1)中回复
全句译:我认为把重点放在多元化上以及采取各种实际措施是很有必要的.
问题补充回复
(1)不可省
这里不可省是因为其引导虚拟语气有两种表达形式
It is high time that ..did/should do .
如果省略"should",那么从句的谓语动词只能用另外一种形式过去时.
(2)不可省.
引导词"that"只有在引导宾语从句时可省.
而It is imperative that.中的that引导的是主语从句,"it"只是形式主语替代后面的主句放在了句首
(3)两个"that"都不可省
A:由于前一"that"引导的宾语从句比较长,且句构复杂,因此一般不可省
B:"that"只有引导宾语从句可省(特殊情况除外),故这里不可省
If you still feel confused,leave a message please!

是虚拟语气!主句would have paid 从句had insisted 都是过去时的虚拟语气.he really wanted it.是过去时是事实,是条件状语从句中的原因状语从句.这句话的含义是,如果售货女孩如果坚持的话,他就会为那个房子付双倍的价钱,因为他真的想买.

是的,把它翻译就是

1,该句型中的从句部分用SHOULD +动词原形
2,看形容词,如果是:strange,natural,necessary,important,等,以及insisted,ordered,suggested,等
例句,it is necessary that you should be present at the meeting,你有必要参加会议

D

en

是用这些短语造句吗??

祝学习进步!如有帮助 请尽快采纳 谢谢!

是啊,第一个had 是助动词,第二个是have 的过去分词,对过去事情的虚拟假设的条件句的谓语动词形式是：had done ,主句的谓语动词是would should might +have done（would 是‘将要’,should 是‘应该’,might 是‘也...

是should而且这个should 可以省略 类似的还有advice,suggest等等

2,3可以,4后面无论接表语还是状语从句,都是一般过去时表示现在,过去完成时表示过去,1你应该很熟啊,不说了哦~

虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一.虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测.
Ⅰ用以表示虚拟条件的虚拟语气
⒈ 用if条件从句表示的虚拟条件,是虚拟条件最普通的方式.
① 虚拟现在时表示与现在事实相反的假设,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/ could/ might +动词原形,例如：If I were in your position I would marry her.
② 虚拟过去时是表示与过去事实相反的假设,if 从句的谓语形式用过去完成时即had＋过去分词,主句用would / should / could / might + have +过去分词,例如：If it had not rained so hard yesterday we could have 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 have been so painful now.这个句子在高中出现频率颇高.
④ 但是,如果后果用了虚拟语气,而条件却用陈述语气,这种用法是错的.
⒉ 除了表示虚假条件外,if从句还可以表示对将来的推测,由于是将来还没有发生的,所以谈不上是真实的还是虚假的,只能说这个事情发生的可能性有多大.一般情况下,可以用陈述语气的if从句来表示对一个未来事实的推测,这个事实是完全可能发生的.If从句的谓语形式用一般过去式或用were to / should +动词原形,主句用would / should /could/ might +动词原形,例如：Jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.（1996年1月四级第44题）
⒊ 有时可以把含有助动词、情态动词、be或have的虚拟条件句中的连词if 省去,而将had , should, were 等词提到主语之前,即用倒装结构,这时候,如果出现not等否定词,否定词需放在主语后面.这种结构在口语中很少使用,但频频出现在各类考试中出现,例如：If it had not rained so hard yesterday we could have played tennis.→Had it not rained so hard yesterday, we could have played tennis.
⒋ 大多数的虚拟条件通过上面所讲的两种方法表达,但在个别句子中也可以通过介词without和介词短语but for表达,副词otherwise等表达出来.例如：We didn't know his telephone number; otherwise we would have telephoned him.（1995年6月四级第46题）值得注意的是,包含but for的句子,谓语动词必定要用虚拟形式,但包含without等短语的句子,谓语动词未必一定要用虚拟语气.
⒌ 有时虚拟条件不是明确地表达出来,而在蕴含在用but引导的从句里,于是便出现了有谓语动词是虚拟语气的主句加上谓语动词是陈述语气的but从句构成的并列复合句,例如I would have hung you but the telephone was out of order.在这样的句子里,如果主句没有用虚拟语气,或者从句用了虚拟语气,都是错的.
Ⅱ用在宾语从句中的虚拟语气
⒈ 在表示愿望的动词wish后的宾语从句中,需用虚拟语气.（wish后的that 常省略）,根据主句时态,从句谓语时态相应退后一位,例如：How she wished his family could go with him.
⒉ 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的宾语从句中需用虚拟语气.谓语动词用(should) +动词原形.值得注意的是,如果宾语从句的动词是否定的,否定词not的位置应在动词之前,而不是动词之后.例如：The head nurse insisted that the patient not be move.另外,如suggest表达“暗示”,insist表示“坚持某种说法”时,后面的从句不用虚拟语气,例如：Her pale face suggests that she is ill.或He insisted that he did not kill the boy.
除此之外,上述动词也要求用虚拟式
① 在It is+上述动词的过去分词,其后所跟的主语从句中,如It is suggested that pupils wear school uniforms.
② 在上述动词相应的名词形式作主语+连系动词,其后的表语从句中,例如His suggestion was that classed be re-scheduled.
③ 在对上述动词相应的名词进行解释的同位语从句中,如：The workers raised the demand that their pay be increased to cope with the inflation.
⒊ would （had）rather , would sooner也用来表达主观愿望,它们之后的宾语从句中需用虚拟语气.谓语动词用过去式表示现在或将来,用过去完成式表示与过去事实相反,例如：I would rather he went right now.
Ⅲ其他形式的虚拟语气
⒈ it is +necessary等形容词后,that主语从句中虚拟形式使用,这类形容词包括necessary, important, essential, imperative, urgent, preferable, vital, advisable等,例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce every single word correctly.
⒉ 在It's (high/about) time 之后的定语从句中需用虚拟语气.谓语动词用过去式,例如It is high time that you went to school
⒊ 虚拟语气在as if / as though 引导的方式状语从句中的应用（谓语动词形式与wish后的宾语从句基本相同）表示与现在事实相反或对现在情况有怀疑,谓语动词用过去式.例如：He felt as if he alone were responsible for what had happened. 表示过去想象中的动作或情况,谓语动词用过去完成式.
⒋ 在lest 引导的状语从句中,谓语动词多用虚拟语气,(should )+ 动词原形.例如： The mad man was put in the soft-padded cell lest he injure himself.（1998年1月四级第38题）
⒌ 在if only 引起的感叹句中需用虚拟语气.谓语动词用过去式或过去完成式.例如： Look at the terrible situation I am in! if only I had followed your advice.
虚拟语气：表示动作或状态不是客观存在的事实,而是说话人的主观愿望、假设或推测等.如：
①If I were a bird, I could fly in the air.如果我是一只小鸟,我就能在空中飞行.
②I wish I could pass the examination.我希望我能通过考试.
③May you succeed!祝您成功!
虚拟语气在语法里算得上是个难点.让我们就从最简单的开始吧.
虚拟语气详解运用:
简单句中的虚拟语气
一、情态动词的过去式用于现在时态时,表示说话人的谦虚、客气、有礼貌、或委婉的语气,常用于日常会话中.如：
⑴.Would you be kind enough to show me the way to the post office?请你告诉我去邮局的路好吗?
⑵.It would be better for you not to stay up too late.你最好别熬夜到很晚.
二、表祝愿.
1、常用“may+动词原形”表示祝愿,但愿,此时may须置于句首（多用于正式文体中）.
⑴、May good luck be yours!祝你好运!
⑵、May you be happy!祝你快乐!
⑶、May you do even better!祝你取得更大成就!
⑷、May you have a good time. 祝愿你玩的痛快.
⑸、May the friendship between us last long. 祝愿我们的友情天长地久.
⑹、May you be happy. (注意那个be ) 祝你幸福.
2、用动词原形.例如：
(1).Long live the people! 人民万岁!
(2).“God bless you,”said the priest.牧师说：“愿上帝保佑你!”
(3).Have a good journey! 祝愿你旅途愉快!
三、表示强烈愿望.（该类型虚拟语气谓语仅用动词原形,第三人称单数也不加“s”）
(1).God save me．
(2).Heaven help us．
四、表命令
1.命令虚拟语气只能用在第二人称(you),而且通常省略主语(也就是you).
2.句子尾通常加上感叹号：!
3.虚拟语气动词用一般现在时态(Simple Present),如：work, be , go
4.否定形式的命令语气,可用助动词do,加上not.
(1). Work !
(2). Work harder !
(3). Be more alert ! (虚拟语气动词Be)
(4). You go out !
(5). Do not work so hard. (do not 表示否定的虚拟语气)
(6). Don't be afraid. (口语中常用don't 代替do not)
五、在一些习惯表达中.如：
(1).You’d better set off now.你最好现在就出发.
(2).I’d rather not tell you the secret.我情愿不告诉你这个秘密.
第三部分：名词性从句中的虚拟语气
第一节：宾语从句(Subordinate Clasue)中的虚拟语气
一、在动词wish后的宾语从句中的虚拟语气
在动词wish后的宾语从句中的虚拟语气,常省去宾语从句的引导词that.
一）、对现在情况的虚拟（与现在的事实相反）：
从句用过去式或过去进行式(时间上是同时的).其句子结构为：宾语从句的谓语be和were(was),实义动词用过去式.例：
1. I wish (that可省略,下同)I knew the answer to the question.(wish, 动词过去式knew)我希望知道这个答案.(事实上是不知道)
2. I wish it were spring in my hometown all the year around.(wish, were)但愿我的家乡四季如春.(事实上不可能)
3. I wish I were a bird.(wish, were)但愿我是只小鸟.(事实上不可能)
4. When she was at the party,she wished she were at home.(wished,过去虚拟动词were)(事实上并不在家)
5. Now that he is in China, he wishes he understood Chinese.(wishes,过去虚拟动词understood)
现在他在中国,他希望能懂得中文.(事实上并不懂)
6. When we begin the trip, they will wish they were with us.(will wish,过去虚拟动词were)(事实上并不和我们在一起)
二）、对过去情况的虚拟（和过去的事实相反）：
用wish表示对过去事情的遗憾.其句子结构为：宾语从句的谓语用过去完成时,或would, could, might+现在完成时.例：
1. I wish (that可省略,下同)I hadn't wasted so much time.
我后悔不该浪费这么多时间.(事实上已浪费了)
2. He wishes he hadn't lost the chance.
他真希望没有失去机会.(其实已失去)
3. We wished he had spoken to us.
(wished,had + spoken)(事实上他并没同我们讲)
4. I wish you had called earlier.
(wish, had + called)(事实上已迟了)
5. They will wish they had listened to us sooner.
(will wish,had + listened)(事实上并不如此)
例题分析：I wish I ______ longer this morning, but I had to get up and come to class.
A. could have slept B. slept C. might have slept D. have slept
动词wish后面接从句,表达不可能实现或与事实相反的情况时,谓语动词要用虚拟语气,即用过去式（表示现在发生的动作）或过去完成式（表示过去发生的动作）.本题后半句谓语动词have用的是过去时had
to get up and come, 所以前面要用过去完成时表示过去发生的动作.所以, 选项A)could have slept是答案
三）、对将来情况的虚拟(表示将来的主观愿望)：
从句动词"would/should/could/might + 动词原形"(时间上较后)(请注意：主句和从句的主语不相同).用wish表示对将来事情的愿望.例：
1. I wish it would stop raining.(虚拟动词would+动词原形stop)
我希望雨能停止.(事实上雨还在下着呢)
2. I wish you would be quiet.(would + be)
我希望你安静一些.(事实上那家伙还在吵着呢)
3. You wished she would arrive the next day.(would + arrive)
你希望她第二天会到.(事实上她还没到)
4. I wish she would change her mind.(would + change)
我希望她会改变主意.(呵呵,女孩子可没那么容易就改变主意喔)
5. He will wish we would join him the following week.(would + join)
(只是希望我们和他在一起,实际上还没在一起)
四）、注意：
1.如果将wish改为过去式wished, 其后that 从句中的动词形式不变.例如：
I wished I hadn't spent so much money.
我要是那时没有花掉那么多钱就好了.
2. 如果that 从句中用would , 一般表示对现状不满或希望未来有所改变或请求
I wish he would answer my letter.
I wish prices would come down.
I wish you would help me.
I wish you would stop asking silly questions.
二、在表示建议、命令、要求、忠告等动词的后面的宾语从句中的虚拟语气
由于这些动词本身隐含说话者的主观意见,认为某事应该或不应该怎样,这些词语后面的“that”从句应用虚拟语气,且均以“should+动词原形”表示这种语气,但事实上“should”常被省略,故此从句中谓语动词用原形,常用的此类动词有：
表示“要求”的：ask, desire, request, demand, require, beg
表示“提议、劝告、建议”的：move, prpose, suggest, recommend, advise, vote
表示“决定、命令”的：decide, order
表示“主张”的：maintain, urge
表示“同意、坚持”的：consent, insist
例如：
1.The doctor suggested that he (should) try to lose his weight.
2.He insisted that we (should ) tell him the news.
3.When I suggested that he try shaving cream, he said, “The razor and water do the job. ”(当我建议他用刮胡膏时,他说“剃刀和水就行了”.)
4.He pursued various theories for several days until I suggested we take the toy apart to see how it did work. (他费了几天功夫寻找理论根据,直到我建议拆开看看它是如何转动的.)
5.One can suggest that students should spend two or three years in an Englishspeaking country. (我们建议学生应在说英语的国家呆上两三年.)
在表示命令、建议、要求等一类动词后面的从句中虚拟语气很普遍,其结构如：
order, suggest, propose, require, demand, request, insist, command, insist +... (should) do
6.I suggest that we (should) hold a meeting next week.
7.He insisted that he (should ) be sent there.
但注意：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.
8.she insists that she is right.
9.she insisted that I should finish the work at once.
或者说,suggest, insist不表示建议或坚持要某人做某事时,即它们用于其本意暗示、表明、坚持认为时,宾语从句用陈述语气.
10.The guard at gate insisted that everybody obey the rules.
三、在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中的虚拟语气
在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中,我们经常用“should＋动词原形(或完成形式)”,表示惊奇,怀疑,不满等.
I never thought that he should be such a brave young soldier.
我们从来没想到他是个如此勇敢的小战士.
四、would rather , would sooner,had rather, would (just) as soon ,would prefer之后的宾语从句中的虚拟语气
would rather , would sooner, had rather, would (just) as soon,would prefer（希望）也用来表达主观愿望,它们之后的宾语从句中需用虚拟语气.谓语动词用过去式表示现在或将来,用过去完成式表示与过去事实相反.表示”宁愿做什么”或"对过去做的事的懊悔".
(1).I would rather he came tomorrow than today.
(2).John would rather that she had not gone to the party yesterday evening.
(3).Don' t live in the world, I would rather( I would just as soon) you die.
(4).I would rather you go tomorrow.
(5).I would rather everything hadn' t happened in the past.
(6).The manager would rather his daughter did not work in the same office．经理宁愿她女儿不与他在同一间办公室工作.
(7).To be frank,I'd rather you were not involved in the case．坦率地说,我希望你不要卷入这件事.
(8).You don't have to be in such a hurry．I would rather you went on business first．你没有必要这么着急,我宁愿你先去上班.
(9).I'd rather you didn't make any comment on the issue for the time being．我倒希望你暂时先不要就此事发表意见.
(10).Frankly speaking ,I'd rather you didn't do anything about it for the time being．坦白地说,我宁愿你现在对此事什么也不要做.
(11).Wouldn't you rather your child went to bed early?为什么你不愿让你的孩子早点上床呢?
(12).I would just as soon you had returned the book yesterday．我真希望你昨天把这本书还了.
注：①若某人愿自己做某事,would rather后用动词原形
I would rather stay at home today．
②would rather．．．than．．．中用动词原形
I would rather stay at home than go out today．
五、“had hoped”后的宾语从句中的虚拟语气
用“had hoped”表示原来希望做到而实际上未能实现的事情,其宾语从句的谓语用“would+动词原形”.
I had hoped that she would go to the U.S. and study there, but she said she liked to stay in China.我原本希望她到美国去念书,但她说她喜欢留在中国.
主语从句中的虚拟语气
一、“It is (was)+形容词（或过去分词）+that……”结构中的虚拟语气
在形如“It is (was)+形容词（或过去分词）+that……”结构中,使用某些表示愿望、建议、请求、命令、可能、适当、较好、迫切、紧近、重要等形容词后的主语从句的谓语也用虚拟语气.其表达形式为should ＋动词原形或省略should直接用动词原形（美国英语中省去should）
常用的形容词：* natural (自然的), appropriat (适当的),advisable (合适的), preferable (更可取的), better (更好的)* necessary (必须的), important (重要的), imperative (急需的), urgent (急迫的), essential (本质的), vital (必不可少的)* probable (很可能的), possible (可能的)* desirable (极好的)advisable（合理的）,compulsory（必须的）,crucial（紧急的）,desirable（理想的）,essential（必要的）,imperative（迫切的）,incredible（惊人的）,necessary（必要的）,possible（可能的）,strange（奇怪的）,urgent（紧迫的）.
常用的过去分词(Past Participle):* required (需要的), demanded (要求), requested (被请求的), desired (要求)* suggested (建议), recommended (推荐)* orderd (命令)
1. It is necessary that we (should 可省略,下同）have a walk now.(necessary, should + have) (表示有需要去散步)
2.It was necessary that we (should) make everything ready ahead of time.(necessary, should + make) (表示有必要事先做好准备)
3. It is required that nobody (should) smoke here.(required, should + smoke) (表示要求不要在此抽烟)

注：在上述所列形容词后面用that引出的宾语从句中,谓语动词也要用虚拟语气.
10.I don't think it advisable that Tom be assigned to the job since he has no experience．汤姆缺乏经验,指派他做这项工作我认为是不恰当的.
二、在It is ＋名词＋that…的主语从句中的虚拟语气

requirement,resolution,shame,suggestion,surprise,wish,wonder等.

虚拟语气用在表语从句或同位语从句中
当某些表示建议、请求、命令等主观意向的名词作主语时,其后的表语从句或同位语从句需用虚拟语气,其表达形式为should ＋动词原形或直接用动词原形.这类名词常见的有：

选B
这是过去时的虚拟
前面是had+__,后面是should,could+have(本来应该能----
这是一种形式记住就行了

选were
表示与现在事实相反的情况：
从句：If 主语+过去时 主句：主语+should/would/could/might+do
eg1．If I were you,I would take an umbrella.如果我是你,我会带把伞（事实：我不可能是你） 　　2．If I knew his telephone number,I would tell you.如果我知道他的电话号码,我就会你.（事实：不知道）
这道题是与事实相反的,因为他不可能是超人,所以填Were(Be动词的过去式在虚拟语气里一般都用were)

回答：答案是选C 全句为：Only if Mr Li gets a job can he have enough money to build his house.全句意为：只有当李先生有了一份工作,他就能有足够的钱来建造他的房子.
这是一个复合句,主句是he can have enough money to build his house；.Only if Mr Li gets a job是条件状语从句,;由于状语从句前有only强调,根据语法,主句要进行倒装,即,将he can改成 can he.
这是一个真实意义的条件句,不需要用虚拟语气.
另,本人估计提问者将only if 和 if only 记混了,if only意为“只要...就好了”,它的后面才要接虚拟语气.如：
If only I could see him once.
我只要再见到他一次就好了.
•x05If only I knew a way to have my friend here for a day.
我真希望我有办法让我的朋友在这里呆上一天.
欢迎提问,

你说的动词原形指的是 句子中的 be 而不是 delighted
句子中的 be 符合你说的用法
delighted是形容词,在句中

这个句子无虚拟语气.suggest doing表示建议做某事,所以用stopping.should是情态动词,直接加动词原型.who had been driving all day是从句,剩下是主句.手机登的没法写了关于虚拟语气你Hi我吧

有错,应该是some useful skills that we will use
或者是some useful skills that will be used by us
但是这两个都不是虚拟语气哦,你的题目要求你用虚拟语气的话,你可以用下面的句式
it is (high) time + 动词过去式
e.g. It is high time mastered some .

虚拟语气的话有三种情况：1,现在：if+一般过去式,主句would+动原
2,过去：if+过去完成时,主句would+have done
3,将来：if+were to/should do,主句would do

很希望你能吧你的题目列出来，不然这样，很难理解的。

1本词所描写的是一副萧瑟的秋景，白浪滔天，遥想昔人，心怀感慨，浪滔天，风萧瑟，无限苍茫
倾注了诗人忧国忧民的胸怀。
2想到了当年魏武帝面对此情此境的感想，心怀激动，并且抒发了自己的壮志豪气，暗写了当时的大好河山，新中国的美好前途
3最后句
4挥鞭是一个很有内涵的动作，显示了魏武帝的当时挥鞭的壮志，指挥千军万马的豪情，雄迈而浑厚，真英雄也...

我的解读是两者皆非.

首先这条句子的语气是带有嘲讽口吻,后句中 as if 引导的从句正是起到这层作用.
换言之,具体这个motivational tool 是否存在虽无定论,但说这句话的人是抱持不以为然的态度.

基于此,对“他们”的 frustration 和 confusion 也就当成在看笑话了.

If only I had had more money,I would have bought those new clothes. 与过去事实相反（过去完成时+would/should+have+过去分词）If only I had more money,I would buy those new clothes. 与现在事实相反 （过...

How I wish it never happened
I should study hard
It is the facts prove that what you said are not true
I find it is difficult that learning in the noise

可以

1.他希望他没讲那样的话.
He wished he_hadn't say things like_that.
6.国王命令囚犯明天要实施死刑
The king ordered that the prisoners__ tomorrow want to implement __the next day.
10.我不知道他的电话号码,否则我就打电话给他了
I _don't know__his telephone number,other-wise I_would have telephoned_him.

条件状语从句包括真实条件句和虚拟条件句（也叫虚拟语气.
1.真实条件句是和事实相符的假设.
If he comes,I will call you.
虚拟条件句适合事实相反的假设.
If I were a bird,I would fly.
2.二者的动词形势不一样.
(具体的动词形式语法书上都有）

后面基本上接to do.从句可用虚拟语气

应该是 should i eat something,i would become fat

所谓虚拟就是假的意思,就是与事实不相符的.判断一个句子是否用了虚拟语气,留看它的时态是否与真实的时态一致.这样说来虚拟语气的用法也就不在乎两种,一是借助于助动词,二就是“提前”时态.明白了这个道理,你再看书本上的枯燥语法讲解很容易就明白了.祝学习快乐!

如果一个人想要保持身体健康,那么每天的运动是必须的.
It is ...that ...somebody (should) do sth.
虚拟语气, should可以省略 should 后需用动词原型
