零条件句

啥叫“零条件句”?这四种条件句怎么区分?
先让我们看一下这几类条件句的含义。
零条件句：If the temperature rises, the bear thinks spring is in.(常态描述)
If you decide to study in the UK, you must pass IELTS.(常态描述)
第一条件句：If it rains tomorrow, we will have the P.E. class in the gym.(未来的可能性)
第二条件句：If I had the same chance, I would go to Australia.(对将来的虚拟)
第三条件句：If he had had another choice, he would not have sold his house.(对过去的虚拟)
但是，无论上面哪一种情况的例句，都无法解释下面这句(前半句是对过去的虚拟，后半句是对将来的虚拟)：
If he hadn't been murdered yesterday, he would be taken to the court tomorrow as scheduled. (如果他昨天没有被谋杀，按照流程明天会被带到法庭。)
语法分为“研究性语法”和“教学性语法”。
研究性语法以语法和语言结构本身为研究对象，重在探讨语言的规律，是学术性研究。
教学性语法以帮助学生更高效地运用语言结构为目的，比如通过一些类似的情境和句子，让学生学习某个语法现象。
从语法研究的角度来说，条件句的确可以大致按照您说的那样来分类(凌哥在前面已经修正)。然而，有一些教师喜欢将研究性语法术语使用到自己的语言课堂中。这种情况，打个比方，就是老师非要将“你父亲”说成“你的上一代男性直系亲属”才感觉是“到位”了、“科学”了、“严谨”了!对于学生(而非语言研究者)来说，会使用“你父亲”不就够了么?!
在英语教学中，应当避免使用这样的学术性语言来跟学生解释语言现象。你看，作为老师的你，也不能区分得很清楚，学生当然会越听越糊涂的。
教学生的时候，要利用情境和语境来驱动学生理解语义、呈现语法结构，让学生感悟语言结构与语义之间的联系。
比如：
呈现一个哭的娃娃和一个“no food”的空碗：A baby cries if it is hungry.
呈现明天的日期和天气预报的图标：We will go to the zoo if it's sunny tomorrow.
利用语境，促进学生的抽象思维能力：-- I refused their offer yesterday. -- If I were you, I wouldn't have done that.
并同样利用情境和语境来促使学生模仿使用。

真实条件句,虚拟语气.
当我们陈述了一个事实，而又不是很有把握，就可以在陈述句后加一个简短问句，称为反意疑问句。首先看以下例句：（1） You like calssical music, don't you? 你也喜欢古典音乐，对吗？(2 He lived in Vienna, too,didn't he? 他也住在维也纳，对吗？（3）Your parents can swim, can't they? 你父母会游泳，是吗？（4） Tony doesn't like classical music,does he? 托尼不喜欢古典音乐，对吗？（5） This music isn't very popular, is it? 这音乐并非十分流行，对吗？从以上句子可以看出，反意疑问句是由“助动词/ 系动词be（肯定或否定）+主语（代词）” 构成的。在反意疑问句的构成中要注意以下几点： 1.前面当陈述句如果是肯定的，反意疑问句就要用否定形式，如（1）、（2）、（3）；前面的陈述句如果是否定的，反意疑问句就要用肯定形式，如（4）、（5）； 2.反意疑问句的主语必须是代替前面主语的代词； 3.翻译疑问句的谓语动词在时态和人称上要与前面陈述句谓语动词保持一致。陈述句部分如果有标识否定意义的词，反意疑问句要用肯定式。如：They have never visited his home, have they? 他们从来没有到他家玩过，是吧？在回答反意疑问句时，要特别注意英、汉两种语言习惯的差别。试看下面当例句：——Mr Smith isn't American, is he? 史密斯先生不是美国人，对吧？——Oh yes, he is.不对，他是美国人。可以看出，在英语中，无论问题是怎样问的，只要答语的事实是肯定句，就要用YES；只要答语的事实是否定的，就要用NO. 编辑本段英语18种特殊的反意疑问句介绍 1.祈使句。祈使句后一般加上will you或won't you构成反意疑问句，用will you 多表示“请求”，用won't you 多表示提醒对方注意。例如：Look at the blackboard, will you/ won't you?看黑板，好吗？Let引导的祈使句有两种情况：1Let's...,后的反意疑问句用shall we或shan't we。例如：Let's go home, shall we/ shan't we? 回家吧，好吗？还可以用may I来表示征求对方的同意或许可。2Let us/me...后的反意疑问句用will you或won't you。例如： Let me have a try, will you/won't you? 让我试一试，行吗？ 2.感叹句。感叹句后加反意疑问句时，其反意疑问句需用be的一般现在时态的否定形式。例如：What fine weather, isn't it? 多好的天气啊，是吧？ 3. 当陈述部分谓语动词是need, dare, used to，且这些词被用作实义动词时，其反意疑问句需用do的适当形
if条件句中的虚拟语气讲解
虚拟语气(一) 一、考点聚焦 1、虚拟语气用于条件状语从句中 If I were a boy, I would join the army. If she had time, she should go with you. If h e had taken my advice, he would have succeeded in the competition. If i t were to rain tomorrow, the football match would be put off. If I had time, I would attend the meeting. If he had hurried ,he could have caught the train. If I were to go abroad ,I would go to America 如果我是你，我就会努力学习 If I were you, I would work harder at my lessons. 如果我知道他的电话号码，我就给他打电话了 If I had known his telephone number, I would have called him. 如果明天下雨的话，我们会取消比赛． If it should \were to rain, we would call off the match.
使用虚拟条件句要注意的几点： １．当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为：错综时间条件句“，动词的形式要根据它所表示的时间作出相应的调整． If you had followed my advice , you would be better now. 如果你听我的建议，你现在就会痊愈了． If you had studied hard before, you would be a college student now. 如果你努力学习的话，你现在就会是大学生了． If they had worked hard, they would be very tired now.(从句说的是过去，主句指的是现在) ２．省略句 在条件句中，可省略if，把were ,had, should 提到句首，变为倒装句式．If I were at school again, I would study harder. Were I at school again, I would study harder. If you had come earlier, you would have met him. Had you come earlier, you would have met him. If it should rain tomorrow, we would not go climbing. Should it rain tomorrow, we would not go climbing. Were I a boy, I would join the army. Had he taken my advice, he would have succeeded. Were it not for the expense, I would go to Britain. 2、虚拟语气用于名词性从句 （1）虚拟语气在宾语从句中的运用。 ①“wish + 宾语从句”表示不能实现的愿望，译为“要是……就好了”等。 表现在过去时 表过去过去完成时 表将来would, might, could＋动词原形 I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. I wish (that) I were a bird. I wish (that) I had seen the film last night. I wish (that) I would\could go.

Well, if you hadn't told him, he wouldn't have known it. No, Jack, he likes to call my teachers. If he had found it out by himself, I would
虚拟语气和错综条件句和含蓄虚拟
虚拟语气表示说话人所言内容不是事实，而是一种假设、愿望、建议、请求、命令或猜测，有时只是说话者的主观愿望，或表达他/她的强烈情感，谓语动词用特殊形式。 一．虚拟语气在if 条件句中的用法 If从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。条件句中的虚拟语气根据不同的时间有三种不同的形式。 2. 条件中的虚拟语气的举例 (1) 现在时的条件句中的虚拟语气。若与现在事实相反，虚拟语气的条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：如： If he were free, he would help us. 要是他有空的话，他会帮助我们的。If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。 If I were you, I would never do that. 如果我是你,我决不做那件事。 If it weren’t for (=But for) your help, I would still be homeless. 若不是你帮忙，我现在还是无家可归。 If I had more money, I would buy a car. 我要是有再多一点钱，我就买
汽车了。 If there were no subjective mood，English would be much easier. 要是没有虚拟语气，英语就会容易得多了。 If I knew his telephone number，I would ring him up. 我要是知道他的电话号码，我就给他打电话了。 If I were you, I would go there at once. If my classmates were here, they would help me. If I were you, I would accept the job. If classes were smaller, children would learn more. If I were ten years younger, I would start all over again. If I had enough money, I would buy a large house. If I had time, I would go shopping with you. If I knew all the answers to all your questions, I would be a genius. If he were here now, we would ask him about it. If I had time, I would study French. If I knew her number, I could ring her. (可惜我不知道) If there were no gravity, we should not be able to walk. (实际上地球引力始终存在。) If I knew the answer, I would tell you. (实际上我确实不知道，所以肯定不能告诉你。) If I had money on me, I would lend you some.

if可以引导真实条件句和虚拟条件句.
Unit 4 一. if 条件句 if可以引导真实条件句和虚拟条件句。真实条件句表示在假设的条件下，能够实现的情况。在这种情况下，主句和从句的谓语动语随各自的人称和时态发生变化，同时if条件句遵循“主将从现”的原则，即主句用一般将来时，从句用一般现在时表将来。 If it doesn’t rain tomorrow, we will go for a picnic. 如果明天不下雨，我们去野餐。 如果if条件句用来描述说话人认为与事实相反的内容，或仅是一种愿望，假设、猜测等，我们称为虚拟条件句。 If I got rich , I would travel around the world. 如果我有钱了，我将周游全世界。 二.虚拟语气 区分条件从句主句例句 ★与现在事实相反If+主语+过去 式（be多用 were）… 主语+would/should/could/ might+动词原形… If I were rich, I would buy a big house. 如果我 有钱，我将买一所大房 子。 与过去事实相反If+主语+had+ 过去分词… 主语 +would/should/could/might+ have+过去分词… If I had read this article earlier, I would not have made this kind of mistake.如果我早读过这 篇文章，我就不会犯这 样的错误了。 与将来事实相反If+主语+过去 式（be多用 were） /should+动词 原形/were to+ 动词原形… 主语 +would/should/could/might+动 词原形… If it were to rain tomorrow, the match would be put off. 如果明 天下雨，比赛就会被推 迟。
虚拟语气和错综条件时间从句区别
虚拟语气和错综条件时间从句区别 You would be much better now if you had taken my advice. （错综时间条件从句） You would have been much better now if you had taken my advice.(虚拟） 假若你当时听我的话，你现在就会好多了 在表示虚拟语气的句子中，条件从句表示的动作与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各自所表示的时间来调整，这种现象叫做错综时间虚拟语气。You would be much better now if you had taken my advice.假若你当时听我的话，现在就会好多了。（从句过去，主句现在）would have been 是与过去事实相反的非真实条件句 一般来说虚拟语气中的混合时态的句子都有具体的时间词来进行提示的，比如 说： If we had arrived at the shopping mall earlier, we would get more gifts now. 如果我们早点来商场的话（过去的时间虚拟），我们现在就可以拿更多的礼物了 （现在的虚拟）。 这是两个不同时间的虚拟语气，有相应的时间词来提示的，now来提示后句的时 间是现在而不是和前面一样的过去。 If we had arrived at the shopping mall earlier, we would have got more gifts. 如果我们早点来商场的话，我们就会拿到更多的礼物了。（已经拿了礼物了，但是实际上过去拿的时候没有拿到那么多） 如果从句和主句都表示过去的，那从句用had done,主句用 would ,could,might,should+have done 如：If you had taken my advice,you would not have been late for the meeting yesterday.如果从句表示过去的，但主句表示现在的，从句用had done,主句用would ,could,might,should+do,如：If you had taken my advice,you would not be late for the meeting now.这种一般都有个时间，如果没有表示时间的词也可以从上下文看出。 虚拟语气的用法错误。

虚拟语气与各种句型
虚拟语气与各种句型 一、I wish句型中的虚拟语气 I wish后面的宾语从句，表示不可能实现的愿望。其动词形式有三种：1. 动词用过去式，表示与现在事实相反的一种愿望。2. 动词用过去完成式，表示与过去事实相反的愿望。 3. 动词用would/should +动词原形，表示与将来事实很可能相反或不可能实现的愿望。如： I wish I were a doctor. 我希望我是一名医生。 I wish you hadn’t given him my telephone number. 我真希望你没把我的电话号码给他。 I wish you’d come back before Christmas. 我多么希望你在圣诞节之前回来。 [典型考例]How I wish every family_________a large house with a beautiful garden!(NMET02上海春) A. has B. had C. will have D. had had 二、If only句型中的虚拟语气 If only引导的句子表示“但愿”，“要是……就好了”。其用法和I wish 的句型基本相同，只是更具感情色彩。在If only句型中，动词用过去式，表示一种意愿或假设；动词用过去完成式，表示希望出现和过去事实相反的情况；动词用would +动词原形，表示一时很难实现的愿望。如： If only I had more time to think about it! 但愿我有更多的时间去考虑它。 If only the explosion had not happened! 爆炸要是没有发生就好了。 If only he had not eaten so much sugar! 要是他不吃那么多糖就好了。 [典型考例1]If only he_________quietly as the doctor instructed, he would not suffer so much now. (NMET2000上海) A. lies B. lay C. had lain D. should lie [典型考例2] Look at the trouble I am in! If only I_________your advice. （NMET’03 上海） A. followed B. would follow C. had followed D. should follow 三、“It’s (high) time that…”句型中的虚拟语气 “It’s time that...”句型表示“该是……的时候了”，谓语动词用一般过去式，有时为了强调，在time之前加high一词，表示“早该是……的时候了”。如：
all的四种用法
at all的四种用法 一、用于否定句 at all 用于否定句，主要是加强否定的语气，意思是：根本不，一点也不。如： It wasn’t difficult at all. 这一点也不难。 There was nothing to eat at all. 根本没什么可吃的。 That kind of belief is not at all unusual. 那种看法极为常见。 I haven’t got any idea at all about what happened. 我根本不知道出了什么事。 It’s quite extraordinary；I can’t understand it at all. 这件事太不寻常了，我根本没法理解。 Mike doesn’t enjoy classical music (very much) at all. 迈克根本就不(是很)喜欢古典音乐。 有时与hardly, few, seldom, scarcely 等半否定词连用。如： It hadly rained at all last summer. 去年夏天没怎么下雨。 It scarcely mentions women at all. 它几乎一点都未提及妇女。 注：在否定句中，at all 可位于句末，也可跟在否定词后。如： He’s not at all stupid. 他一点儿都不傻。 He isn’t tired at all. /He’s not at all tired. 他一点也不累。 另外，在口语中单独说not at all, 可用来回答感谢或道歉。如： A: Thank you very much. 多谢你了。 B: Not at all. 不客气。 A: I’m sorry to keep you waiting. 对不起，让你久等了。 B: Oh, not at all. 噢，没关系。 二、用于疑问句 at all 用于疑问句，主要加强疑问的语气，意思是：到底，究竟，难道不。如： Did you know him at all? 你究竟认识他还是不认识他？ Are you at all worried about it? 你难道对此不担心吗？ Have you read any of the report at all? 那份报告你到底有没有读一点？ Did it play any role at all in the presidential campaign? 这件事在总统选举中到底起作用没有？ 三、用于条件句 at all 用于条件句，主要用于加强if的语气，意为：假若，既然，即使，反正。如：If you do it at all, do it well. 既然要做，就把它做好。 He’ll come before supper if he comes at all. 他要是来，准在晚饭以前。 If you want to consult me at all, give me a ring. 如果你确实要和我商量，可以给我打个电话。 四、用于肯定句 at all 用于肯定句(较少见)，意为：不管怎样，竟然。如： I was surprised at his coming at all. 我很奇怪，他竟然来了。 It’s a miracle that you returned at all. 你竟然回来了真是奇迹。 That he was rescued at all was a matter of coincidences. 他的获救实属巧合。 在肯定句中，尤其见于前面有any的场合，即用于强调any的意思。如： I’ll do any job at all—even road-sweeping. 什么工作我都干——扫街都行。 You can come whenever you like---any time at all. 你什么时候想来就来——无论什么时候都行。
虚拟语气的错综条件句子
虚拟语气的错综条件句子，也就是常说的混合条件句，即虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 例如：1）If I were you，I wouldn’t have missed the film last night．如果我是你，我就不会错过昨天晚上的那部电影。（从句与现在事实相反，主句与过去事实相反。） 2）If he had followed the doctor’s advice，he would recover already．如果他遵照医生的劝告，现在病就好了。（从句与过去事实相反，主句与现在事实相反。） 混合虚拟语气 有时主句和从句的谓语动词指不同的时间，这时需要用混合虚拟语气。一般来说，在这种情况下，主从句谓语动词指代的时间不同，所以我们又可以错综时间条件句，在这种虚拟情况，动词形式应根据实际情况灵活使用，在做这些题目时候尤其要注意每道题目的提示语：时间
状语。绝大多数情况下，从句或者主句都有相关的时间状语，这是解题的关键。 If you that late movie last night, you wo uldn”t be so sleepy.t be so sleepy.
