青岛雅思之If 条件句
条件句
就雅思语法方面（多样性和准确性），分享一个非常重要的语法点：条件句（2个）第一类条件句(first conditional):公式（基本组成部分）：if+present tense , will/won’t/might/could+do何时用：something we feel is a probable future result好掌握，实用性强口语中如何使用第一类条件句？例句：1.Do you enjoy cooking?Yes, I do. I am good at cooking. If i have enough time,,i will cook some authentic Chinese cuisines for my family on weekends, especially at a family reunion.2.Where do you live?(高频考题）I live in a high-rise apartment. If i find a well-paid job, i will buy a luxury house as a gift for my parents.3.Do you like shopping?Yes, i DO. If i have enough free/leisure time, i will hang out with my best friends in the shopping mall on weekends,4.Do you like traveling?Yes, i do.Traveling can be great for self-discovery and if i travel abroad regularly, it will broaden my horizon.写作也同样：论证老师应该拿高工资（明星拿的多）If the government doesn’t raise the salary for teachers, this will make them feel undervalued and thus diminish their sense of job satisfaction . This, in return, will have a negative effect on teachers’ students.关于网购的问题：In the future, i think more people will do their shopping online. But if the Internet shopping becomes more popular, many traditional shops will lose their customers.（实体店）第二类条件句（second conditional):公式：if +past tense, would/wouldn’t+do何时用：refers to imaginary(想象）；hypothetical situations(假设）；talking about a possible event in the future(将来有可能发生的一个事情）例句：Would you like to change your name?No, i don’t want change my name. In fact, i am very fond of my name coz it has quite a deep and significant meaning, and as well as this,my mother chose it for me so she doesn’t want me to change it. Actually i am sure i will never change my name.注意：考官用的是would提问，表示假设，不肯定，只是可能（答案过于肯定），考官在听答案时，在语法点方面有一个basic rule. 即：第二类条件句（假设）类似的题目还有Would you like to change your job/live near the sea/learn another foreign language/live in a foreign country?Would you like to move to another city in the future? (既然用would提问，回答用would是一个绝佳的机会可以展现grammatical range,对语法的驾驭能力非常不错）If i had the chance,i would like to move to a new city coz if i lived in a different city , i would make lots of new friends and i could try a lot of new kinds of food. Also, i might be able to find a decent/well-paid job.写作部分（第二类条件句）often used to give advice例：公共交通建设In my opinion, governments should invest more money in public transport . If rail and bus services were more reliable, fewer people would need to drive.健康饮食（junk food)Schools have an important role to play in children’s health. If school banned junk food,they would help to reduce the problem of children obesity.。
条件状语从句在雅思写作中的应用
大作文举例只会用if？是时候换换啦——条件状语从句在写作中的应用王洪亮今天跟大家分享一个老生常谈的知识点，什么叫做条件状语从句呢？通俗来讲，往往由引导词if或unless引导的状语从句叫做条件状语从句。
在英文中，条件是指某一件事情实现之后，其它事情才能发生，通常译作“假如”。
在写作中，条件状语从句十分好用，拿过来就能用，可以起到很好的突出强调作用。
一提到条件句，很多同学马上就会想用if来引导。
首先，我们一起来看以下七个句子：Part A：1 You can borrow my dictionary if you return it before you go home.2 You cannot go to university if you do not have good grades.3 Pollution will get worse if we continue to live in a throwaway society.4 Many developed countries are willing to waive the Third World debt if the mon-ey is reinvested in education and medicine.5 Some countries will never be able to rectify their deficits even if they work hard.6 Computers are difficult things to understand, even if you read a lot of books about them.7 Crime is a problem, even if you go to relatively safe countries.这些句子都是由if 引导的条件句（ even if 可以是条件也可以是让步状语从句），这些句子固然很好，但是是不是有些千篇一律呢？条件状语从句不仅仅限于if，下面给大家介绍一些可以替换if 的方式。
If引导的条件句
16.The foreign friend speaks Chinese so well as if he ___ a Chinese. A. is B. was C. should be D. were
.—If he ___, he___ that food. —Luckily he was sent to the hospital immediately. A.was warned; would not take B.would be warned; had not taken C.had been warned;would not have taken D.would have been warned; had not taken
对过去的虚拟
ቤተ መጻሕፍቲ ባይዱ
If you had taken my advice, you would not have made such a mistake. If I hadn’t lived among the peasants for five years, I shouldn’t have been able to write such good novels. If he had been sent to a better hospital, the man’s life might have been saved. If I had been more careful, I could have done better.
1.If you ___ (arrive) ten minutes earlier, you could have seen them off. 2.If they___ (not help) us ,our experiment would have failed. 3. ___ I not ___ (forget) his telephone number, I would have rung him. 4.He is busy now. If he ___ (be) free, he___ (go) with you.
if四种条件句
Main clause would/could/might + have + past participle
If I had studied hard, I would have passed my exams.
IIf you had studied hard, you wouldn’t have failed your exam.
If you go to London, you must look right before crossing a street
If clause If + Past Simple
Main clause would / could / might + verb
If I were an astronaut, I would travel in a spaceship.
If I met a Martian, I wouldn’t understand him.
?
IfI aved
If I didn’t understand him, I would come back to the Earth.
If clause If + Past Perfect tense
If I were an astronaut, I would travel in a spaceship.
If I travelled in a spaceship, I would go to Mars.
If I went to Mars, I would meet a Martian.
Nice to meet you!
If I go to London,

if引导的条件状语从句讲解和练习(答案)
条件状语从句一、条件状语从句通常由if（如果）, unless（除非），as long as（只要）引导。
例如：If it rains tomorrow, we won’t go to the park. 如果明天下雨，我们就不去公园了。
Unless weather stops me, I go for a walk every. 我每天都会去散步，除非遇上坏天气。
Our parents will be pleased with our performance as long as we try our best.小试牛刀：1、只要我们竭尽全力，父母就会满意我们的表现。
Our parents will be pleased with our performance _____ _____ ______ we try our best.2、如果人人为保护环境做出贡献，世界将会变得更美好。
______ ______ ______ _____ _______ to protecting the environment, the world will become much more beautiful.二、if引导的条件状语从句（1）“if从句+祈使句”的句子。
其实，if作为一个连词，主句也可以是其他形式的句子。
例如：If you want to go, please let me know.If the green light isn’t on, wait for a minute.(2)“祈使句+ and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。
注意：A. “祈使句+ and + 陈述句”可以转化为if引导的肯定条件状语从句，而且主语是第二人称。
B. “祈使句+ or + 陈述句”可以转化为if引导的否定条件状语从句，而且主语是第二人称。
例如：Study hard and you will pass the exam. =If you study hard, you will pass the exam.Hurry up, or you’ll be late. =If you don’t hurry up, you’ll be late.考题(2010重庆中考)Work hard，________ you may catch up with your classmates soon.A.orB.butC.andD.yet思路解析：本句是“祈使句＋and”的句型，句意为“努力学习，你会很快赶上其他同学的”，and在句中表示承接关系，所以选C项。

雅思考试成绩自考试之日起2年内有效。
以下是yjbys网店铺整理的关于雅思写作中长难句语法规律，供大家参考。
定语从句纵观剑桥真题上面的考官范文，定语从句乃是当之无愧高频句，现摘取如下较典型的例句与读者共同探讨：This has been driven by technological and scientific breakthroughs that are changing the whole way we view the world on an almost daily basis.句中，that 引导的定语从句：that are changing the whole way we view the world on an almost daily basis. 是对先行词technological and scientific breakthroughs 的限定说明，它不影响主句：This has been driven by technological and scientific breakthroughs. 的语法结构。
因此，我们的出结论：定语从句的功能是对句中某个名词作限定说明，使用方法就是在名词后+that/which(先行词为事物)或who(先行词为人)并且把这些引导词当成主语，接着补充成一个句子就行啦。
状语从句再看看同样使用频率较高的.状语从句：For example, if sufficient sky trains and underground train systems were built and effectively maintained in our major cities, then traffic on the roads would be dramatically reduced.句中，if 引导的是条件状语从句：if sufficient sky trains and underground train systems were built and effectively maintained in our major cities. 主句一般而言表示基于此条件的结果。
if条件句的使用和搭配
if条件句的使用和搭配【文章标题】：If条件句的使用和搭配【引言】：If条件句是英语中一种常用的句型，通过使用if引导从句，可以表达某种条件下可能发生的情况。
在英语交流中，合理运用if条件句能够在表达观点、提建议或进行假设推理等方面起到关键作用。
本文将深入探讨if条件句的使用方法和搭配，帮助读者更好地理解和运用该句型。
【正文】一、基本形式的if条件句1.1 如果现实情况下可能发生的情况If + 现在时，将来时（主句）如：If it rains tomorrow, I will stay at home.如果明天下雨，我会待在家里。
1.2 与现实相反的假设情况If + 过去时，主句将有would/could/might + 动词原形或could/might + have + 过去分词如：If I were you, I would study harder.如果我是你，我会更加努力学习。
如果他早点起床，他可能赶上火车。
If he had gotten up earlier, he could have caught the train.1.3 对未来的具体假设情况If + 过去将来时，主句将有would/could/might + 动词原形或could/might + have + 过去分词如：If it were to rain tomorrow, I would cancel the outdoor activity. 如果明天要下雨，我会取消户外活动。

青岛雅思培训之浅议If引导的条件句在雅思范文中的使用
浅议If引导的条件句在雅思范文中的使用济南新航道杜林屡次给学生分析范文时，总会有部分自以为是的考生说：“老师，你不要跟我讲范文了。
这文章我看得懂，我语法很好的。
”这就是学生们常步入的误区之一，考生往往局限于阅读看的懂，可完全没有能力落实在笔头上。
例如If引导的条件句，是中国学生初中阶段就会学习到的基础语法点。
大部分的雅思考生都有能力写出语法正确的句子，但是有能力运用到雅思写作中的却寥寥无几。
概括而言，If引导的条件句常做为一种论证手段出现在写作的正文部分，也常用在结尾段提出合理化建议。
对于雅思写作正文部分而言，由于大部分学生都苦于没有材料将自己的论点进行合理论证，所以举例法是考生的首选。
但是雅思正文部分一般要写二至三段，重复使用举例法的作文是无法取得高分的。
所以需要考生掌握多种论证方法灵活运用，此时，假设法也不失为良策。
所谓假设法，即在提出论点的前提下，通过假设论点所提内容不被采纳或假设论点相反情况下的不良结果，达到对比突出主题句的目的。
例如郑庆利老师编著的书中所引用考官范文所示：例1：If he has little knowledge of computer skills, a student willlag behind the times, in danger of being excluded from what is going on in the world.这个条件句是该主体段落的最后一句话。
该段主题句阐述了大学生掌握电脑操作技能的重要性。
接下来的两句话对该主题句进行正面扩展。
而例1这个条件句则通过假设缺乏电脑知识与技巧的不良后果，对比突出主题句中掌握电脑技能的重要性。
虽然没有运用复杂的长句和语法结构，但此处假设条件句的运用，十分恰当得体，且符合英文思维逻辑。
If条件句在逻辑关系中的功能，不容考生小觑。

雅思备考之语法中条件句类型分析
雅思备考之语法中条件句类型分析条件句结构在不同的使用条件下会有不同的使用形式，也是学生非常容易混淆或者搞错的句型结构。
首先我们要先知道什么叫做条件句，从这个表面意思我们就可以知道，条件句是用来表达在某种情况下会发生什么句子，意思为：如果……，某人/某事会…….表示“如果……”，通常我们会想到的是if。
我们要先把这个句子分为两部分，一部分是由If引导的从句部分，另一部分是句子的主句。
1 第零条件句：这种句子只用于描述事实或者真理，例如一些科学现象。
结构：从句和主句部分都使用一般现在时。
例句：If you add some salt in it, it becomes salty.If I see a caterpillars, I get frightened.2 第一条件句：这种句子用于在某个条件下，会产生某个结果(确实会发生)。
这种句子也叫真实条件句结构：从句部分使用一般现在时，主句部分使用将来时(有时会用shall, can, may等情态动词代替will)。
例句：If it rains, I will stay at home.If you work hard, you can improve your grade.3 第二条件句：这种句子用于在某个不太会发生的条件下，会产生某个结果。
或者和现在事实相反的情况。
这种句子也叫非真实(虚拟)条件句结构：从句部分使用一般过去时(be动词要换成were)，主句部分使用would+动词原形。
(也可以用could, should, might代替would)例句：If I were you, I might do it better.If I could choose any work I want, I would be a singer.接下来我们可以来比较这两个句子：If I go outdoor, I will go to the park.If I went outdoor, I would go to the park.通过比较这两个句子我们可以发现，这两个句子的意思都是如果我可以出门，我会去公园。
