While he loves his students, he is very strict with them. (3).while作并列连词用，意思为“而，然而”，表前后意义上的对比或转折。 e.g.There’s plenty of rain in the southeast, while there's little in the northeast. Some people waste food while others haven't enough. ★注意:while与but的区别 二者都有“而，然而”之意,但while强调二者的对比，而but强调前后的转折关系。 (2).when 引导的时间状语从句，可指时间的一点，也可以指一段时间，从句的谓语动词可用终止性动词，也可用持续性动词。when（特指）引导的从句表示的具体的时间，从句的动作和主句的动作可以同时，也可以先于主句的动作。whenever（泛指）指任何一个不具体的时间。 ①When I got home, he was having supper. ②When I was young, I liked dancing. ③When he has finished his work, he takes a short rest. ④When I got to the cinema, the film had already began. 【重点提示】 1.when 也可作为并列连词，连接两个并列句， “那时”，“这时”相当于and then , and at that time.这时不可被as, while 替代。 We were about to go out when the teacher came in. We hadn’t been watching TV for a long time when there was a power failure. 2.when 还可作“在......的情况下”解释，这时也不可被as, while 替代。 Why did you walk there when you have a car? Whenever you meet difficulties, you must get it over. 无论你什么时候遇到困难，你必须克服它。 (3).as 用as时主句和从句的动作往往同时发生，一般同延续性动词连用，有时可译作“一边…...一边…...”。 As time went on, his theory proved to be correct.随着时间的推移，他的理论被证明是正确的。 As we walked, we talked.我们边走边谈。 As it grew darker, it became colder. As she came to know him better, she relied on him more. 注意： 1.当从句的谓语动词是延续性动词时, when, while, as 有可能互相替换. While/When/As we were still laughing, the teacher came in. 2.另外，as还可以引导定语从句。当as放在句首引导让步状语从句时，句子采用部分倒装语序。 2.名词词组引导时间状语从句 有时名词every/each time（每次），the next time（下一次），the next day（第二天），the first time，for the first time, every day, the year等，也可起从属连词的作用，引导时间状语从句。 I thought her nice and honest the first time I met her. =I thought her nice and honest I met her for the first time. 注意：the first time放在句中，for the first time放在句末。 Every time you get back at night, you drop your shoes on the floor. I didn’t have a penny the last time I saw you. 3.as soon as表示“一…就” I’ll tell him as soon as/ the moment (that)/the minute (that)/ immediately/ directly/ I see him. 4.since引导的时间状语从句 以since引导的从句或短语作状语时，主句常用完成时，从句常用一般过去时。 ①Since I was a child, I have lived in England. ②We have been friends ever since we met at school. 【重点提示】 1.主句若表示“已经有多少时间”可用一般时。 How long is it since you were in London? It is just a week since we arrived here. 2.since 引导的从句中的谓语动词如果是瞬间动词，则表示“自从这个动作的开始”以来； 若是延续性或状态性的动词则表示“自从这个动作的结束”以来。 How long is it since you worked here? 你不在这儿工作已经几年了？ It is 3 years since I was ill. 我病愈以来已经3年了。 It is just a week since we arrived here. 我到这儿已经一周了。 5.before引导的时间状语从句 (1).before“在....之前”  I’ll be back before you have left. 你离开之前我就会回来。  Before I could get in a word, the tailor had measured me.(还没来得及…就)。 (2).before“....之后才”It was some time before sb. did sth.和It will be some time before sb. does sth. It was three days before he came back. 他三天后才回来。 It will be three days before he comes back. 他三天后才会回来。 It was not long before he came back. 不久他就回来了。 在这里，记两个短语：long before 不久之前 before long 不久以后 6.till/until和not…until引导的时间状语从句 till和until 都表示“直到”， 两个词常可换用， 主要有下列两种用法。 (1).如果主句谓语动词为非延续性动词，如come, go, enter, return, start, reach, finish等，主句用否定式， 从句用肯定式，而且是“not...until”结构。 He won’t go to bed till/until she returns. He didn’t come until he had gone over his lesson. (2.)如果主句谓语动词为延续性动词， 如stay, remain等，主句用肯定式。 He remained their till she arrived. You may stay here until the rain stops. 7.once引导的时间状语从句 once（一旦）的用法在某种程度上，相当于after. Once I arrive in Shanghai, I will call you. Once he wants to do something, nobody can change his mind. 要点二、地点状语从句 地点状语从句一般由where，wherever（相当于no matter where）引导。 一）where作连词引导地点状语从句时，意思是“在/向……的地方”。 1.You should have put the book where you found it.你本来应该把书放回原来的地方。 2.You’d better make a mark where you have any questions.哪儿有问题，你就在哪儿做个记号。 =Where you have any questions,you’d better make a mark. 3.We must camp where we can get water.我们必须在能找到水的地方露营。 4.Where they went,they were warmly welcomed.他们走到哪里都受到热烈的欢迎。 二）．比较：where引导的地点状语从句与定语从句的区别 引导定语从句时，where是关系副词，在从句中作地点状语，其前面有表示地点的先行词，where引导的从句修饰先行词。引导状语从句时，where是从属连词，它引导的从句修饰主句的谓语动词，where前面没有表示地点的先行词。 Bamboo grows best in places where it is warm and where it rains often. =Bamboo grows best where it is warm and where it rains often. （where引导定语从句，引导地点状语从句。） 温暖而多雨的地方最适合于竹子生长。 有时，where引导的地点状语从句兼有抽象条件含义，可放在主句的前面；而where引导的定语从句则不能放在主句的前面。 Where there is water,there is life.有水的地方就有生命。（where引导地点状语从句。） 三）wherever相当于no matter where，意思是“无论到哪里，无论在哪里”。wherever引导的地点状语从句多位于句首。 1.Wherever he goes,he always takes a notebook with him.无论走到哪里，他总是带着一个笔记本。 2.Wherever there is smoke,there is fire.无风不起浪。 3.Wherever he may be,he will be happy.无论在什么地方，他都会快乐的。 =No matter where he may be,he will be happy. 要点三、比较状语从句 比较状语从句一般由as…as(和一样)，not as/so…as（与……不一样），than（比）,the more…, the more…（越……越……）引导。 The director gave me a better offer than he gave Dick. 导师给我的提议比给狄克的好。 In recent years travel companies have succeeded in selling us the idea that the further we go, the better our holiday will be. 近几年旅游公司已成功地对我们灌输了去得越远，假日越好的观点。 John plays football as well as, if not better than, David. 如果说约翰的足球踢的不比大卫好，至少和他踢的一样好。 I can’t run as/so fast as he can. 我不能跑得他那样快。 【易错提醒】 1. when可表时间点或时间段，从句谓语可以是瞬间动词或延续性动词 2. as强调两个动作伴随进行 3. While只表时间段，从句谓语只能是延续性动词。 4.主将/情/祈从现 1．I didn’t realize he was a famous scientist ________ you told me. A．because B．although C．unless D．until 【答案】D 【详解】句意：直到你告诉我，我才知道他是一位著名的科学家。 考查连词辨析。because因为；although尽管；unless除非；until直到。not…until…表示“直到……才”，是固定搭配。这里的主句是否定式“didn’t realize”，而从句是“you told me”，所以用until的话，整个句子的意思就是“直到你告诉我，我才意识到他是著名科学家。” 这完全符合逻辑。故选D。 2．Mum has been working in this school since she ________ from university in 2000.

He spoke for such a long time that people began to fall asleep. 2.so…that...与such…that...的区别 这两种结构都可引导结果状语从句。so是副词，后接形容词或副词；such是形容词，后接名词。 (1).单数名词 在so...that与such...that中间出现的是单数名词，且该名词前有形容词修饰时，这两种结构可互换，但要注意它们的词序不同:such+ a/an+形容词十名词=so+形容词+a/an+名词。 She is such a good teacher that all of us love her.= She is so good a teacher that all of us love her.她是一位很好的老师，我们都敬爱她。 (2).不可数名词或复数可数名词 如果被修饰的是不可数名词或复数可数名词时，一般须用such...that。 He made such rapid progress that before long he began to write articles in English.他进步很快，不久就开始用英语写文章。(不可数名词) They are such interesting books that we all want to read them.这些书是那么有趣以致我们都想读一读。(复数可数名词) (3).名词前有many, much, little, few修饰时 如果不可数名词或复数可数名词前有many，much，little，few修饰时，则用so…that。 I’ve had so many falls that I’m black and blue all over.我摔了好多次跤，周身青一块紫一块的。 George had so little money that he had to get a job.乔治没有钱，所以他不得不找工作干。 They are such little children that they can’t do anything.他们是小孩，什么事情都干不了。 要点三、让步状语从句 让步状语从句由though，although，as，even if (though)，however，whatever，whoever，whenever，no matter +wh词，等引导。 1.even if, even though, although，though引导的让步状语从句 这四个词（词组）都有“虽然、即使、尽管”的意思。even if和even though带有较强的意味，语气比although和though强。though比although通俗，但不如although正式,都不能和but连用，但可以和yet, still或nevertheless连用。可以放在主句前面也可以放在主句后面。even if，even though所接的句子常用虚拟语气。 Although journalism seems like a good profession, I would prefer to be a teacher. 虽然新闻业好像是一个很好的职业，但是我更喜欢当老师。 Although he is considered a great writer, his works are not widely read. 虽然有人认为他是一个大作家，但是他的作品读得并不广泛。 We won’t give up even if we should fail ten times. 即使是我们失败十次，我们也不会放弃。 He might have given you more help, even though he was very busy. 尽管他很忙，他可能给了你更多的帮助。 2.as或though引导让步状语从句（高二讲解部分倒装时会更好地掌握） 3.由no matter+ wh词和由疑问词+ever引导让步状语从句 由no matter引导，表示“不管；无论”；由疑问词＋ever引导，表示“不管，不论”。这类词有：whatever，whichever，whoever，however， whenever，wherever等,他们相当于no matter+ what（which，who，how，when， where），都不能与but，so，and等并列连词同时使用。 We’ll have to finish the job, however(no matter how) long it takes. No matter what(Whatever) you do, don't tell him that I told you this. No matter how pure the water looks, I prefer not to drink it. No matter where (Wherever) you go, I would keep you company. 4.由whether...or...引导让步状语从句 由whether...or...引导让步状语从句表示“不论……还是”，提供两种对比的情况。 I shall go, whether you come with me or stay at home. 不论你和我一起来还是留在家中，我都要前往。 Whether we like a particular piece of news or not, all we have to do is sit in front of the tube and “let it happen”. 不管我们喜欢不喜欢一条消息,我们所能做的只是坐在电视机前，“让它过去”。 1．You have to leave now ________ you can catch the early bus.

While he loves his students, he is very strict with them. (3).while作并列连词用，意思为“而，然而”，表前后意义上的对比或转折。 e.g.There’s plenty of rain in the southeast, while there's little in the northeast. Some people waste food while others haven't enough. ★注意:while与but的区别 二者都有“而，然而”之意,但while强调二者的对比，而but强调前后的转折关系。 (2).when 引导的时间状语从句，可指时间的一点，也可以指一段时间，从句的谓语动词可用终止性动词，也可用持续性动词。when（特指）引导的从句表示的具体的时间，从句的动作和主句的动作可以同时，也可以先于主句的动作。whenever（泛指）指任何一个不具体的时间。 ①When I got home, he was having supper. ②When I was young, I liked dancing. ③When he has finished his work, he takes a short rest. ④When I got to the cinema, the film had already began. 【重点提示】 1.when 也可作为并列连词，连接两个并列句， “那时”，“这时”相当于and then , and at that time.这时不可被as, while 替代。 We were about to go out when the teacher came in. We hadn’t been watching TV for a long time when there was a power failure. 2.when 还可作“在......的情况下”解释，这时也不可被as, while 替代。 Why did you walk there when you have a car? Whenever you meet difficulties, you must get it over. 无论你什么时候遇到困难，你必须克服它。 (3).as 用as时主句和从句的动作往往同时发生，一般同延续性动词连用，有时可译作“一边…...一边…...”。 As time went on, his theory proved to be correct.随着时间的推移，他的理论被证明是正确的。 As we walked, we talked.我们边走边谈。 As it grew darker, it became colder. As she came to know him better, she relied on him more. 注意： 1.当从句的谓语动词是延续性动词时, when, while, as 有可能互相替换. While/When/As we were still laughing, the teacher came in. 2.另外，as还可以引导定语从句。当as放在句首引导让步状语从句时，句子采用部分倒装语序。 2.名词词组引导时间状语从句 有时名词every/each time（每次），the next time（下一次），the next day（第二天），the first time，for the first time, every day, the year等，也可起从属连词的作用，引导时间状语从句。 I thought her nice and honest the first time I met her. =I thought her nice and honest I met her for the first time. 注意：the first time放在句中，for the first time放在句末。 Every time you get back at night, you drop your shoes on the floor. I didn’t have a penny the last time I saw you. 3.as soon as表示“一…就” I’ll tell him as soon as/ the moment (that)/the minute (that)/ immediately/ directly/ I see him. 4.since引导的时间状语从句 以since引导的从句或短语作状语时，主句常用完成时，从句常用一般过去时。 ①Since I was a child, I have lived in England. ②We have been friends ever since we met at school. 【重点提示】 1.主句若表示“已经有多少时间”可用一般时。 How long is it since you were in London? It is just a week since we arrived here. 2.since 引导的从句中的谓语动词如果是瞬间动词，则表示“自从这个动作的开始”以来； 若是延续性或状态性的动词则表示“自从这个动作的结束”以来。 How long is it since you worked here? 你不在这儿工作已经几年了？ It is 3 years since I was ill. 我病愈以来已经3年了。 It is just a week since we arrived here. 我到这儿已经一周了。 5.before引导的时间状语从句 (1).before“在....之前”  I’ll be back before you have left. 你离开之前我就会回来。  Before I could get in a word, the tailor had measured me.(还没来得及…就)。 (2).before“....之后才”It was some time before sb. did sth.和It will be some time before sb. does sth. It was three days before he came back. 他三天后才回来。 It will be three days before he comes back. 他三天后才会回来。 It was not long before he came back. 不久他就回来了。 在这里，记两个短语：long before 不久之前 before long 不久以后 6.till/until和not…until引导的时间状语从句 till和until 都表示“直到”， 两个词常可换用， 主要有下列两种用法。 (1).如果主句谓语动词为非延续性动词，如come, go, enter, return, start, reach, finish等，主句用否定式， 从句用肯定式，而且是“not...until”结构。 He won’t go to bed till/until she returns. He didn’t come until he had gone over his lesson. (2.)如果主句谓语动词为延续性动词， 如stay, remain等，主句用肯定式。 He remained their till she arrived. You may stay here until the rain stops. 7.once引导的时间状语从句 once（一旦）的用法在某种程度上，相当于after. Once I arrive in Shanghai, I will call you. Once he wants to do something, nobody can change his mind. 要点二、地点状语从句 地点状语从句一般由where，wherever（相当于no matter where）引导。 一）where作连词引导地点状语从句时，意思是“在/向……的地方”。 1.You should have put the book where you found it.你本来应该把书放回原来的地方。 2.You’d better make a mark where you have any questions.哪儿有问题，你就在哪儿做个记号。 =Where you have any questions,you’d better make a mark. 3.We must camp where we can get water.我们必须在能找到水的地方露营。 4.Where they went,they were warmly welcomed.他们走到哪里都受到热烈的欢迎。 二）．比较：where引导的地点状语从句与定语从句的区别 引导定语从句时，where是关系副词，在从句中作地点状语，其前面有表示地点的先行词，where引导的从句修饰先行词。引导状语从句时，where是从属连词，它引导的从句修饰主句的谓语动词，where前面没有表示地点的先行词。 Bamboo grows best in places where it is warm and where it rains often. =Bamboo grows best where it is warm and where it rains often. （where引导定语从句，引导地点状语从句。） 温暖而多雨的地方最适合于竹子生长。 有时，where引导的地点状语从句兼有抽象条件含义，可放在主句的前面；而where引导的定语从句则不能放在主句的前面。 Where there is water,there is life.有水的地方就有生命。（where引导地点状语从句。） 三）wherever相当于no matter where，意思是“无论到哪里，无论在哪里”。wherever引导的地点状语从句多位于句首。 1Wherever he goes,he always takes a notebook with him.无论走到哪里，他总是带着一个笔记本。 2Wherever there is smoke,there is fire.无风不起浪。 3Wherever he may be,he will be happy.无论在什么地方，他都会快乐的。 =Nomatterwhere he may be,he will be happy. 要点三、比较状语从句 比较状语从句一般由as…as(和一样)，not as/so…as（与……不一样），than（比）,the more…, the more…（越……越……）引导。 The director gave me a better offer than he gave Dick. 导师给我的提议比给狄克的好。 In recent years travel companies have succeeded in selling us the idea that the further we go, the better our holiday will be. 近几年旅游公司已成功地对我们灌输了去得越远，假日越好的观点。 John plays football as well as, if not better than, David. 如果说约翰的足球踢的不比大卫好，至少和他踢的一样好。 I can’t run as/so fast as he can. 我不能跑得他那样快。 【易错提醒】 1. when可表时间点或时间段，从句谓语可以是瞬间动词或延续性动词 2. as强调两个动作伴随进行 3. While只表时间段，从句谓语只能是延续性动词。 4.主将/情/祈从现 1．I didn’t realize he was a famous scientist ________ you told me.

(2).since引导的原因状语从句一般位于主句之前，表示已知的、显然的理由（翻译成“既然”），较为正式，语气比because弱。 Since you are free today, you had better go shopping. (3).as引导的原因状语从句表示附带说明的“双方已知的原因”，含有对比说明的意为，语气比since弱，较为正式，位置较为灵活（常位于主句前，有时也放在主句后）。 As you aare tired, you hadd better have a rest. (4).for引导的原因状语从句表示并不说明主句行为发生的直接原因，可以理解为推断的原因，只提供一些辅助性的说明，for引导的并列句只能位于主句后，要用逗号与主句隔开。 He could’t have seen me, for I wass not there. 要点二、条件状语从句 条件状语从句引导词：if（注意主将从现）, unless=if not, providing/provided that=if, as (so) long as, on condition that, suppose/supposing that, in case, 条件状语从句可以位于主句前面或后面。 1.由if, unless, as/so long as引导 if 表示正面的条件，意为“如果”；unless表示反面的条件，意为“除非，如果不”（if not） If you don't hurry up, you'll be late. 如果你不快点，你就会晚了。 We’ll go there unless it rains. 如果不下雨，我们就去那儿。 2.由suppose, supposing, providing, provided, on condition that和in case等引导 这类连词（词组）意思相近，有：“如果、假设、即使、在……条件下”等意义。 Suppose (Supposing) he is ill, what shall we do? 如果他病了，我们该怎么办？ In case John comes, please tell him to wait. 假如约翰来了，请让他稍候。 You may keep the book a further week provided (that) no one else requires it. 倘若这本书没有其他人想借的话，你可以再续借一个礼拜。 I will lend you the book on condition that you return it on Monday. 如果说你能在星期一还我，我可以借给你这本书。  I shall take an umbrella in case it rains. 我们应该带伞防止下雨 要点三、方式状语从句 方式状语从句一般由as（正如；按照）, as if/as though（好像）, the way等引导。 1.as 和just as引导方式状语从句 这两个连词的意思是“如…，犹如…，正如…”（in the same manner that）。just as 比as的强调性更强。 You must do everything as I do.你们要照我这样去做。 Just as the water is the most important of liquids, air is the most important gases. 正如水是液体中最重要的一种一样，空气是气体中最重要的一种。 2.as if 和as though引导方式状语从句 as if 和as though意为“好像、仿佛”可以用虚拟语气表示不符合事实或与事实相反的情况；也可以用陈述语气表示符合事实的情况。 He walked slowly as if he had hurt his leg. 他走得很慢，好像腿受了伤。 She speaks English as if she were a native speaker.她讲英语俨然像专家。 注意：在It looks as if...,It seems as if...句型中常用陈述语气。 It looks as if it is going to rain.天看上去好像要下雨。 3.the way引导方式状语从句 the way它的作用相当于the manner，后面的引导词常用that引导方式状语，而且经常省略。此时，一般不用in which引导。 We didn't like the way that he treated us. 我不喜欢他对待我们的方式。 【易错提醒】 1. if 如果；unless 除非 2.主将/情/祈从现 3. unless = if not 4. as long as 只要 1．（2025·上海·模拟预测）Your parents will be satisfied ________ you help them with the housework.

The film was so wonderful that we wanted to see it again. He spoke for such a long time that people began to fall asleep. 2.so…that...与such…that...的区别 这两种结构都可引导结果状语从句。so是副词，后接形容词或副词；such是形容词，后接名词。 (1).单数名词 在so...that与such...that中间出现的是单数名词，且该名词前有形容词修饰时，这两种结构可互换，但要注意它们的词序不同:such+ a/an+形容词十名词=so+形容词+a/an+名词。 She is such a good teacher that all of us love her.= She is so good a teacher that all of us love her.她是一位很好的老师，我们都敬爱她。 (2).不可数名词或复数可数名词 如果被修饰的是不可数名词或复数可数名词时，一般须用such...that。 He made such rapid progress that before long he began to write articles in English.他进步很快，不久就开始用英语写文章。(不可数名词) They are such interesting books that we all want to read them.这些书是那么有趣以致我们都想读一读。(复数可数名词) (3).名词前有many, much, little, few修饰时 如果不可数名词或复数可数名词前有many，much，little，few修饰时，则用so…that。 I’ve had so many falls that I’m black and blue all over.我摔了好多次跤，周身青一块紫一块的。 George had so little money that he had to get a job.乔治没有钱，所以他不得不找工作干。 They are such little children that they can’t do anything.他们是小孩，什么事情都干不了。 要点三、让步状语从句 让步状语从句由though，although，as，even if (though)，however，whatever，whoever，whenever，no matter +wh词，等引导。 1.even if, even though, although，though引导的让步状语从句 这四个词（词组）都有“虽然、即使、尽管”的意思。even if和even though带有较强的意味，语气比although和though强。though比although通俗，但不如although正式,都不能和but连用，但可以和yet, still或nevertheless连用。可以放在主句前面也可以放在主句后面。even if，even though所接的句子常用虚拟语气。 Although journalism seems like a good profession, I would prefer to be a teacher. 虽然新闻业好像是一个很好的职业，但是我更喜欢当老师。 Although he is considered a great writer, his works are not widely read. 虽然有人认为他是一个大作家，但是他的作品读得并不广泛。 We won’t give up even if we should fail ten times. 即使是我们失败十次，我们也不会放弃。 He might have given you more help, even though he was very busy. 尽管他很忙，他可能给了你更多的帮助。 2.as或though引导让步状语从句（高二讲解部分倒装时会更好地掌握） 3.由no matter+ wh词和由疑问词+ever引导让步状语从句 由no matter引导，表示“不管；无论”；由疑问词＋ever引导，表示“不管，不论”。这类词有：whatever，whichever，whoever，however， whenever，wherever等,他们相当于no matter+ what（which，who，how，when， where），都不能与but，so，and等并列连词同时使用。 We’ll have to finish the job, however(no matter how) long it takes. No matter what(Whatever) you do, don't tell him that I told you this. No matter how pure the water looks, I prefer not to drink it. No matter where (Wherever) you go, I would keep you company. 4.由whether...or...引导让步状语从句 由whether...or...引导让步状语从句表示“不论……还是”，提供两种对比的情况。 I shall go, whether you come with me or stay at home. 不论你和我一起来还是留在家中，我都要前往。 Whether we like a particular piece of news or not, all we have to do is sit in front of the tube and “let it happen”. 不管我们喜欢不喜欢一条消息,我们所能做的只是坐在电视机前，“让它过去”。 1．You have to leave now ________ you can catch the early bus.
