its never a good idea to exercise too close to bedtime.尽管有规律的锻炼很重要，但临睡前锻炼不是个好主意。2even if 和even though的意思为“即使，纵使”，有退一步设想的意味，多用于书面语中。even if i am very busy, i will give you a hand when you are in trouble.即使我很忙，你处境困难时我也会帮助你。3as引导的让步状语从句多用于书面语，从句常放在句首，语序部分倒装。被倒装的部分可以是表语、状语或动词原形。若表语是单数可数名词，则该名词提前时，省去其前的冠词。hot as/though the night air was, we slept deeply because we were so tired after the long journey.在长途跋涉之后，尽管夜晚的空气很热，我们还是因为累睡得很熟。4no matter(who, what, when, where, which, how)：no matter与whever引导的让步状语从句意义基本一样，no matter引导的从句可位于主句前或主句后。no matter how busy you are, you should set aside half an hour to take exercise.无论你多么忙，你应该留出半小时锻炼身体。5whever(whatever/whoever/whenever/wherever/whichever); however。(1)whever从句中的动词有时可以和may连用；(2)whever可引导让步状语从句，也可引导名词性从句；no matter只能引导让步状语从句。whatever work we do, we should do our best.不管做什么工作，我们都要尽力。6whetheror引导的让步状语从句，意为“不论还是”，提供两种对比情况。well go on with the work, whether we can find the necessary tools or we cannot.不管我们能否找到所需的工具，我们都要把这件工作做下去。7while也可以引导让步状语从句，意为“尽管”，一般放在句首。while my mother loves me very much, she is very strict with me.尽管母亲很爱我，但是她对我非常严厉。典例 (2015浙江高考短文改错)if i was only a child when i studied in that classroom, i will never forget it.ifalthough/though解析：从句意思是“当我在那间教室学习时我只是一个孩子”，而主句意思是“我永远不会忘记”，主从句的关系应该是让步，而不是条件。1when, while和as的用法连词含义及用法例句when“当时候”，可与延续性动词或短暂性动词连用；从句动作可以发生在主句动作之前、之后或与主句动作同时发生when you apply for a job, you must present your credentials.当你申请工作时，你必须递交你的有关证件。while“当时候”，一般与延续性动词连用，从句动作与主句动作同时发生mary made coffee while her guests were finishing their meal.客人们就要吃完的时候，玛丽去煮咖啡了。as“一边一边”，常与延续性动词连用，从句动作与主句动作同时或几乎同时发生as he grew older, he became less active.随着他逐渐长大，他变得不那么活泼了。如果主句表示的是短暂性动作，而从句用延续性动词的进行时表示在一段时间内正在进行的动作时，when, while与as可互换使用。when/while/as i was walking down the street, i came across an old friend of mine.我正沿着大街走时，碰巧遇到了我的一个老朋友。 2before与since的用法(1)before表示“在之前；还未就；还没来得及就”。常用于句型“it will be/was时间段before从句”(在之前还要多久，过了多久才)。john thinks it wont be long before he is ready for his new job.约翰认为不久他就能为他的新工作做好准备。(2)since表示“自从以来”，常用于“it is/has been时间段since从句”结构。该句型表示“自从开始(不做)已经多长时间了”，一般从句的时态用一般过去时，主句中的时态用现在完成时。as is reported, it is over 100 years since tsinghua university was founded.据报道，清华大学已经建立了100多年了。3notuntil表示“直到才”，主句谓语动词必须是非延续性动词。as far as i know, his mother wont go to bed until he returns home every evening.据我所知，他母亲每晚直到他回家才会上床睡觉。4as soon as/hardlywhen/no soonerthan/the moment/the instant/the second/immediately/directly/instantly: hardlywhen和no soonerthan的意义相当于as soon as，但只表示过去发生的事情，主句为过去完成时，从句为过去时，hardly或no sooner位于句首时语气强，而且主句的谓语要用部分倒装。just use this room for the time being, and well offer you a larger one as soon as it becomes available.暂时用这个房间，一有空的大房间我们就给你。5every time/each time/last time/next time/by the time：在时间状语从句中，不能用一般将来时或过去将来时，而要用一般现在时或一般过去时代替将来时。next time you come here, i will tell you.下次你来的时候，我将告诉你。典例 (全国卷)he even scared my classmates away during they came over to play or do homework with me.duringwhen解析：during是介词，不能引导状语从句，when是连词，可以引导状语从句，从句中的动词既可以是短暂性动词也可以是延续性动词。此处需要表示时间的连词，所以用when。1地点状语从句表示地点、方位，通常由where，wherever引导，可置于句首、句中或句尾。地点状语从句在句首时常兼有抽象条件意味。i cannot hear the professor clearly as there is too much noise where i am sitting.因为我坐的地方噪音太大，所以听不清教授在说什么。where theres a will, theres a way.有志者，事竟成。where引导的状语从句和定语从句的区别where引导地点状语从句直接修饰主句的谓语动词，而在定语从句中where作为关系副词要跟在表示地点的先行词后面，即此时有明显的地点名词。when solving the problem a second time, youd better be more careful where you made a mistake.when solving the problem a second time, youd better be more careful in the place where you made a mistake.再次解决这个问题时，你最好在上次出错的地方更仔细一些。 2条件状语从句常用引导词：if/unless/as long as/so long as/in case/so far as/as far as。(1)unless从句的谓语只能用肯定式；unless和ifnot同义，unless是书面语，ifnot是口语，二者通常可以换用。we will have a picnic in the park this sunday unless it rains or its very cold.除非下雨或天很冷，否则我们将在本周日去公园野餐。my parents dont mind what job i do as long as i am happy.我的父母不在意我从事什么工作，只要我高兴就好。(2)条件状语从句的时态在条件状语从句中，常用一般现在时表将来含义；现在完成时表即将完成之后的情况；一般过去时表过去将来的含义。if everyone does his part, the project will surely be a success.如果大家都尽责，这个项目肯定会成功。典例 (重庆高考单项填空)half an hour later, lucy still couldnt get a taxi _ the bus had dropped her.where解析：句意：半小时后，露西仍然没有从下公交车的地方打到出租车。根据the bus had dropped her及句意可知，此处引导地点状语从句，故填where。1目的状语从句(1)so that/in order that引导的目的状语从句中常用情态动词can，could等。in order that引导的从句可位于主句之前或之后，so that引导的从句只能位于主句之后。the police officers in our city work hard in order that we can live a safe life.我们城市的警察为了让我们能过上安全的生活努力工作。(2)for fear that(唯恐，以防)与in case所引导的目的状语从句中，谓语动词有时也用should/might/could动词原形。the boy hid himself behind the tree for fear that his father might see him.小男孩藏在树后唯恐他父亲看见他。take your umbrella in case it should rain.带把伞以防下雨。(3)目的状语从句可以用so as to, in order to等代替，但主句和从句的主语必须一致。he got up early in order that he could catch the early bus.he got up early so as to/in order to catch the early bus.为了赶上早班车，他早早地起床了。2结果状语从句(1)so that前有逗号，引导结果状语从句。we turned up the radio, so that everyone heard the news.我们将收音机调大，所以每个人都听到了新闻。(2)sothat中so后面跟形容词或副词。he was so excited that he couldnt say a word.他太激动了以致于说不出话。(3)suchthat中such后面跟名词，如果名词是单数就要用such a/anthat，还可以转换用sothat，语气较强。jack is so honest a worker that we all believe him.jack is such an honest worker that we all believe him.杰克是个那么诚实的人，我们都相信他。3原因状语从句(1)because用来回答why的提问，语气最强，一般放在主句之后。the old man asked lucy to move to another chair because he wanted to sit next to his wife.那位老人让露西换坐到另一把椅子上，因为他想挨着妻子坐。(2)since表示既然或已知的理由，稍加分析即可表明的原因，多放在句首。since everyone is here, lets begin our meeting.既然大家都到了，咱们开始会议吧！(3)as引导的从句常放在句首，说明次要的原因，主句说明结果，常用于口语中(注意比较：for连接的是并列句)。as he didnt know much english, he looked up the word in the dictionary.因为他不懂太多英语，他查了字典。4方式状语从句(1)as引导状语从句，意为“按照”。do as you are told to.按照你被告知的方式做。(2)as if或as though的意义和用法基本一样；从句中可以用陈述语气表示可能符合事实，也可以用虚拟语气表示与事实相反。jack wasnt saying anything but the teacher smiled at him as if he had done something very clever.杰克没有说话，但老师朝他微笑着，好像他做了什么很聪明的事。5比较状语从句(1)asas; not so/asas; the sameas表示同程度级的比较，肯定句用asas，否定句可用not asas或not soas。he doesnt run so/as fast as jack (does)他没有杰克跑得快。(2)than表示不同程度的比较，主句中用形容词或副词的比较级。he runs less fast than me.他跑得不如我快。典例 (浙江高考单项填空)cathy had quit her job when her son was born such that she could stay home and raise her family.suchso解析：由quit her job以及stay home and raise her family可知，stay home and raise her family是辞职的目的。so
