would have had to和would have to的区别

DBBAC D
我的答案,先凑合着用吧.第7题我觉得是which 或b,第6可能B可能D

首先排除A,D,因为是个现在比,只要用一个比较级就好.
然后这个更开心的不是特指的,不是只有特定的那种,所以选B.

C
dream of doing sth

as luck would have it幸运的话
as是连词后面是从句luck是从句中的主语 would have是从句中的谓语it是从句中的宾语

后半句用了虚拟语气,中间otherwise表转折,所以前半句是过去的事实用was't,选D.

答案：“which”
“幸运的是,我们戴了一幅地图,要是没有它的话,我们早就迷路了.”
如果 "it "或 "this" 或"that"用,就变成了 Luckily ,we 'd brought a road map without it we would have lost our way .这就是两个句子,中间没有连接词了.如果这样改,在 without 前加上 and 就正确了.

would have been 表示过去可能会发生而实际没有发生的事,例如：
If it hadn't rained,we would have got there on time.(实际上是天下了雨,我们当时没有按时到.）
must have been 则表示对过去非常肯定的推测,例如：
He must have been happy at that time.(那时他一定很幸福.）

表示于过去事实相反的假设.
句型：条件从句(if had+done) ,主句(would have done)
过去完成时 should(would) have+ 过去分词
例子:
If she had worked harder,she would have succeeded.
hope this can help!

早就灰心了英语翻译为什么用would have lost heart
翻译并不完全正确.
would have 正确意思是:"已应该会"
所以would have lost heart 的正确翻译应该是:
"早就已应该灰心了" 才对.
很希望我的回答会对你有帮助.如有不明白,可以再追问,并祝你进步!

选B
if 的这种句子分三种.
if-conditional I(1),if-conditional 2 和 if conditional 3
你这个句子现在是第二种,一般是不太可能完成的一个条件.比如说“If I had 1million dollar,I would travel around the world.但事实上是”我“是不太可能有这100万美元的,所以用第二种虚拟的if-conditional.中文里语法叫什么我不是很清楚,只知道英语的,请原谅下.
第二种的在if句里面用simple past （简单过去式）,在主句里面用would+动词原型

would have been/done本应是/做…
不是对将来事情的推测,而是表示与过去事实相反的情况,虚拟语气.
——————————————————————————————————
表示与过去事实相反的情况的虚拟语气构成：
从句：Had+过去分词,主句：Should/would/could/might have done.
例If I had got there earlier,I should/could have met her.如果我早到那儿,我就会见到她.（事实上：去晚了）
而楼主的表示对将来的推测,构成如下：
从句If+主语+ ① should+动词 ② did ③were to do,主句should/would/could/might do
例:If he would come here tomorrow,I should/would talk to him.如果他哪天来这儿的话,我就跟他谈谈.（事实：来的可能性很小）

1E （If 537(的102次方) were calculated,it would have 279 digits.What would the digit farthest to the right be(the ones digit)?如果求到537的102次方,会有279位数,那个位数是多少） （这个的做法瞎蒙的,数学...

would have done 本来会,本可以 常用语虚拟条件句的 主句中
should have done 本应该,应该做而没做
比如：I would have come to see you if I had been free then.如果当时我有空,我本来会来看你的.
You should have worked harder.你应该更加努力学习的（事实上没有）.

“would+have+done”是虚拟语气,表示对过去事情的假设,意思是“本来会做”.
比如你给的这个例句,完整的是 I would have told you all about the boy's story,but you didn't ask me.我本来会告诉你这个小男孩的故事,但是你没有问我.
没有说虚拟语气就必须有配套的从句啊亲...
以下是我找到的关于虚拟语气的知识点,你可以看看哦
一、 “must+have+done”表示对过去事情的肯定推测,译成“一定做过某事”,该结构只用于肯定句.
1.It must have rained last night,for the ground is wet.昨晚一定下雨了,因为地面还是湿的.
2.You must have been mad to speak to the servant.你和仆人说话,一定是发疯了.
二、 “can't+have+done”表示对过去事情的否定推测,译成“不可能做过某事”.
1.Mr.Smith can't have gone to Beijing,for I saw him in the library just now.史密斯先生不可能去北京了,我刚才还在图书馆见过他.
2.Mary can't have stolen your money.She has gone home.玛丽不可能偷你的钱,她回家去了.
三、 “can+have+done”表示对过去行为的怀疑,用于疑问句,译成“可能做过……吗?”.
1.There is no light in the room.Can they have gone out?屋里没有灯,他们可能出去了吗?
2.There is nowhere to find them.Where can they have gone?到处找不到他们,他们可能到什么地方去呢?
四、 “could+have+done”是虚拟语气,表示对过去事情的假设,意思是本来能够做某事而没有做.
He could have passed the exam,but he was too careless.本来他能够通过考试,但是他太粗心.
五、 “may+have+done”表示对发生过的事情的推测,意思是“可能已经”或“也许已经”,用于肯定句中.
—What has happened to George?
—I don't know.He may have got lost.
—乔治发生了什么事?
——我不知道,他可能迷路了.
六、 “might+have+done”表示对过去事情的推测,might与may意思相同,但可能性更小.多用于虚拟语气结构中.
1.He might have given you more help,even though he was busy.他或许会多给你一些帮助,即使他很忙.
2.She might have achieved greater progress,if you had given her more chances.如果你多给她点机会,她可能已经取得更大的成绩.
七、 “would+have+done”虚拟语气,表示对过去事情的假设,意思是“本来会做”.
1.I would have told you all about the boy's story,but you didn't ask me.我本来会告诉你这个小男孩的故事,但是你没有问我.
2.Without your help,I wouldn't have achieved so much.没有你的帮助,我是不会取得如此大的成绩.
八、 “should+have+done”意思是“本来应该做某事,而实际没做.” “shouldn't+have+done”表示本来不应该做某事,而实际做了.含有指责对方或自责的含意.
1.Tom,you are too lazy.The work should have been finished yesterday.汤姆,你太懒惰了,这项工作本来应该昨天就做完的.
2.Look,Tom is crying.I shouldn't have been so harsh on him.看,汤姆哭了,我本来不应该对他如此严厉.
九、 “ought to+have+done”表示过去应该做而实际并没有做,译成“理应做……”,往往表示遗憾.与“should+have+done”用法基本一样.
I ought to have gone home last Sunday.我理应上星期日回家.
You ought not to have given him more help.你不应该帮助他那么多.
十、 “need+have+done”表示本来需要做某事而没有做.“needn't+have+done”则表示“本来不需要做某事而做了”.
I needn't have bought so much wine—only five people came.我本来没有必要买这么多酒,只来了五个人.
He need have hurried to the station.In that case,be wouldn't have missed the train.他本来需要快点去车站,那样的话,他就不会误了火车.
would like to have done sth 本打算做某事
I would like to have read the article,but I was very busy then.
would rather +have done 当时宁愿做了 或没做
I would rather have refuse his offe

应该是c处,将would have had改为would have 这属于if引导的虚拟条件句,对将来事实的假设,在非真实条件状语从句中,谓语动词按正常情况“后退一步”.也就是：
①与过去事实相反,在从句中用过去完成时形式表示.
②与现在事实相反,在从句中用过去一般时形式表示.
③与将来事实可能相反,在从句中用过去将来时形式表示.
主句中则用情态动词would, should, could 等加一个与从句一致的动词形式.
例：If I had come her yesterday, I would have seen him.
If I were a teacher, I would be strict with my students.
If it should snow tomorrow, they couldn’t go out.
四、注意事项
①if条件句中如有were, should, had,可以省去if,并使用倒装语序.
②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were.

“can+have+done”表示对过去行为的怀疑,用于疑问句,译成“可能做过……吗?
“could+have+done”是虚拟语气,表示对过去事情的假设,意思是本来能够做某事而没有做.
“would+have+done”虚拟语气,表示对过去事情的假设,意思是“本来会做”.

C

从答语“or I would have been here sooner” 可知问句的动作与现在有关，have been表示“曾经去过，现在已经回来”，符合本题语境。

“can+have+done”表示对过去行为的怀疑,用于疑问句,译成“可能做过……吗?
“could+have+done”是虚拟语气,表示对过去事情的假设,意思是本来能够做某事而没有做.
“would+have+done”虚拟语气,表示对过去事情的假设,意思是“本来会做”.

如果我陷入爱河,那是因为有你的明眸、你的笑靥,是因为你笑的方式、你做事的风格.
如果我爱错了方式,我还是会义无返顾地爱下去,直到你……也爱上了我.
原谅我陷入了对你的爱,原谅我全心全意地爱着你……原谅我从来不想和你分开,你知道为什么吗?
因为我-爱-你.我们是朋友,我们是很好的朋友.可是对我来说……你是世界上最美丽的女孩,最可爱的女孩……你在我的心里是最重要的,因为……在我的心里……你就是……我的全部!
我的唯一!

还行吧,这只是随便翻译了一下,如果还有更高要求,直译异译或者译成诗歌散文…… 我再来看看!

If I died,what would change?不用have changed,因为是对现在的虚拟语气,所以would do

当然填 which；
which 在这里是关系代词,引导定语从句,修饰先行词 all kinds of books,在从句中做主语；
what 在这里不行,因为 what 是个连接代词,引导定语从句,同时也充当先行词,而这一句里已经有了先行词 all kinds of books；
为了了解 what 的用法,请看这一句：I like what you like （= 我喜欢你喜欢的东西）,这里的 what 既做先行词,也引导定语从句 you like；
如果将其分解,则原句相当于 I like the things which you like ,比较发现 what = the things which,the things是先行词,which 是关系代词.
原句除填 which 外,填 that 也行.

这种虚拟语气的句子按道理是应该配套用的：主句had done +从句would have done.但是有些情况下可以用混合型,也就是不完全配套.would have done也表示虚拟语气,它的含义是“本来能做但没有做”.这两句话,你难理解的是它的否定之否定.
我首先给你分析第二题,第一题你就能懂了.第二题,可以这么转换一下：I would have been early,if I had taken the subway.句子的意思跟你提供的句子是一样的：如果我搭到了地铁,我就会去的很早（不会迟到）.因为这个句子用的虚拟语气,所以他表达的意思是他没搭到地铁,因此他迟到了.所以你可以把would后面的那个not和late一起看出一个“early”.就能明白了.第一题就同理啦.

getting up 没有选项所以没办法定情景,不过知道语法
reget doing sth意思是 后悔做过某事
否定句 reget not doing sth
比较----
reget to do sth 将要做某事,经常接 say / inform sb 这样的告知性词语

如果上面说的那个会议再晚两小时开的话,就太迟了.

这里是“真不巧,”的意思

1.这里是有if引导的与事实相反的条件状语从句,要用虚拟语气,对过去虚拟用过去完成时,所以选C
2句式,find it + adj + to do sth find+宾语+宾补
3.on处于某种状态
4.结合语境,排除CD,C是应该,D是本能够．这里是must表推测,从后面的hasn't turned up可确定是对过去的推测,所以选B
5.wish sb后用虚拟语气,有因yesterday确定为对过去的虚拟同1,所以选C

eg. You should have finished your work. 表示你本应该做完作业而没有完成.
would have done也是对将来的事的虚拟 表示对将来可能发生事情的一种推测

were
考察虚拟语气
真希望我那时候在那里

“would+have+done”虚拟语气,表示对过去事情的假设,意思是“本来会做”.
1.I would have told you all about the boy's story,but you didn't ask me.我本来会告诉你这个小男孩的故事,但是你没有问我.
2.Without your help,I wouldn't have achieved so much.没有你的帮助,我是不会取得如此大的成绩.另外,would have done的确也可用于不是虚拟语气的句子：
1.Jordan never would have done that.
乔丹永远不会这么做.
2.Almost everyone would have done it.
几乎大家都会做.

If I had studied hard,I would have passed the eaxm.
如果我过去努力学习,我就会通过考试.
对过去时间的虚拟

D

regret doing sth.后悔做过某事；regret to do sth.遗憾（抱歉）地要做…

几种常见时态的相互转换
英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式：
一、 一般过去时与现在完成时的转换
在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能.但是,可用别的表达方式：①瞬间动词用于“一段时间 + ago”的一般过去时的句型中；②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用；③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中.请看：
A. He joined the League two years ago.
B. He has been in the League for two years.
C. It is two years since he joined the League.
D. Two years has passed since he joined the League.
二、 一般现在时与现在进行时的转换
在一般现在时中,at加上名词表示“处于某种状态”,如at work（在工作）, at school（上学、上课）等.此短语可与进行时态转换.请看：
Peter is at work, but Mike is at play.
Peter is working, but Mike is playing.
三、 现在进行时与一般将来时的转换
在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作.如：I am coming, Mum! 意为“我就来,妈妈!”请看：
The train is leaving soon.
The train will leave soon.
四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换
“be going to+动词原形”、表示打算、计划要做的事；将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall.在口语中,所有人称都可以用will.请看：
We are going to visit the Great Wall next Sunday.
We shall visit the Great Wall next Sunday.

你完全理解错误了
没错 过去将来完成时态是 would have done
在He said he would let me have the book as soon as he had read it.中,would 是will 的过去式,但是 let somebody do something 是一个动词词组,也就是说let me have 这个let的动词词组的have 与前面的would并不构成过去将来完成时态.是would let 构成 过去将来时.

would have
wish 后面须接虚拟语气.表示将来要做的,用would + 动词原形

生活中有些事在所难免.

would 要更委婉一些,显得更礼貌

will have done 将来完成时
将来完成时是用在表示在将来某一时间以前已经完成或一直持续的动作.经常与before+将来时间或by+将来时间连用,也可与before或by the time短语引导的现在时的从句连用.
would have done 过去将来完成时
过去将来完成时表示从过去观点看将来某时某动作业已完成.这个时态用得相对比较少,通常主要用于转述方面,即用于间接引语中.过去将来完成时由“would+have+过去分词”构成.

I would have asked my english teacher for his autograph, but I was too timid to ask him.

很高兴为你解答.
保证正确率~!
正确答案是：C
【解析】：
A 虽然 B 然而 C 除了；若非 D 如果
根据题意,正确答案为C.
would have done 本来会做...（实际没做）,是虚拟语气的表达.
【翻译】：
若不是迈克没有滑倒,摔倒在赛道上,他可能都赢了比赛了.
祝开心~!

would have代表过去将来完成时.翻译成：就已经.
如：If I had study hard,I would have pass the exam.如果我当时刻苦学习了,我就考及格了.

My father would have a () summer holiday this year 1two months 2two month 3two-months
选4
数量词和形容词中间用-连接
不需要用复数
这是复合形容词修饰名词

因为 迟到 这个行为 在这里 是发生在 交通阻塞 以后的.也就是说 迟到 是交通阻塞以后的事 所以用 将来式 因为两件事都是过去 所以要用过去 然后 再套用虚拟语气 就对了

虚拟语气中,当从句有were 和had时,是可以把had were提前,去掉if来倒装的,
正确答案用的就是虚拟语气的倒装形式,平常确实不怎么见到.
正过来说应该是：If everyone had contributed(过去完成）,we might……（mightwouldcouldshould加have done 的形式)
有had把 had提前,去掉if：Had everyone contributed,we might……
你选的,首先,contribution 是抽象动词,SAT中,抽象动词永远不如直接用它的动词形式；其次,那个passive,指的是你没有用everyone 作主语,动作不是由人发出的,不够主动,用OG上的话来说,就是：“change the subject unnecessarily

would have done
是一个形式，done代表过去分词，would have been是一个具体的，由于句子没动词，故用be动词

答案A 导介词+which引导定语从句,B项缺句子之间的连接词． 查看原帖

非虚拟语气时,就是would 情态动词加动词原形,
have done 就是现在完成时啊
所以和起来 就是将来完成时的用法
过去将来完成时表示在过去看来将来某时会已经完成的动作,它由“would+have+过去分词”构成.如：
She said she’d have finished her exams by then. 她说那时她会已经考完试了.
He knew he arrived she would have gone home. 他知道他到时她会已经回家了

非限定性定语从句中,用which代替前面的内容,用that以错误论处.

I thought - 我以为 (但现在不是这么认为了),故一般用过去式.I thought I loved you then.I thought I lost you.I thought she knew.I thought I knew it all.I thought I did really well on the test.
都是一般的藉口

对过去的虚拟用would have done
比如:if you came here earlier,we would have been there.
事情已经发生过了,所以用have
