2. however表转折关系，语气稍弱于but，连接性也较弱，因而常作插入语。
如：Later, however, he changed his mind. 然后他后来改变了主意。
例：(2018·湖北荆州) 短文填空
Because of an uncommon disease(疾病), he was kept to a wheelchair. 65 , the disease did not stop Hawking from studying.
However 根据上下文可知表示转折，故填however。
3. still多用于肯定句或疑问句，yet常用于否定句。指不管做出多大努力或让步，仍达不到预期的结果。
如：He worked hard, still, he failed. 他干得很卖力，然而他失败了。
He said he hadn’t received a letter from her yet. 他说他至今尚未收到她的信。
4. while表对照关系，但程度弱一些。
如：One lost a leg, another an arm, while a third was killed outright.
一个人没了一条腿，一个人丢了一只胳膊，而另一个人当场死了。
5. though与although同义，一般情况下可互相换用。但although比though更正式，多用于书面语，且多放于句首。在although或though引导的让步状语从句中，主句不能用but，但可使用yet或still。
如：Though / Although they’re expensive, people buy them. 虽然它们很昂贵，人们还是买。
表示因果关系
常见表示因果关系的词：so, for, since, therefore等。
1.for/so“因为，所以”表因果
如：The?dress?was?very?expensive,?so?I?didn’t?buy?it.?那件连衣裙太贵了，所以我没有买。
注意：because为从属连词，接表示原因的从句。意为“因为……，所以……”，但英语却不能用because…so…这样的结构。
例1：(2018·湖南岳阳)I have to study too much I don't get enough sleep.
A. but B. so C. or
B 考查连词的辨析。句意：我必须花太多时间学习因此得不到足够的睡眠。表示“因此”应用so。故选B。
例2：（2018·四川凉山）34. his right hand was hurt, he wrote slowly.
A. Because; so B. Because; / C. Although; but D. Although; /
B 考查连词。句意：因为他的右手受伤了，所以他写得很慢。表因果关系的连词because与so不能同时用，故答案选B。
2. since意为“既然”，表示对方已知的无需加以说明的原因或事实，语气比because弱，但比for强，它引导的从句通常放在主句之前，有时也放在主句之后。
如：Since you are wrong, you should apologize. 既然你错了，你应该道歉。
3. therefore是表示结果而不是原因。相当于for that reason。
如：Rescue workers are therefore drilling a hole. 因此营救人员钻了个洞。
考点二 从属连词

例：（2018?上海中考)Mr Black walked around and offered help____we were doing an experiment.
A.while B.although C.until D.unless

after在……之后。 从句用一般过去时，主句用过去进行时。

--Not yet. Please wait outside your name is called.
A. until B. since C. so
A 考查连词。“打扰一下，轮到我了吗？”“还没呢，请在外面等着，一直到念你名字的时候。”B、C选项填入意思不通。
例2：（2018·湖北随州）Some people won't realize the importance of their health they ______ lose it.
A. because B. after C when D. until
D 考查连词用法。句意：有些人直到失去健康才知道它的重要性。Because因为；after在......之后；when当......时候；until才。“Not …until” “直到……才”。故选D。
as?soon?as 一……就…… 引导的从句常用一般现在时，主句用一般将来时。
如：I will tell him the news as soon as he comes back.他一回来我就告诉他这个消息
例：(2018·四川宜宾中考) She stopped talking _______ her mother came into the room.
A. as soon as B. unless C. though
A 考查连词辨析。as soon as 意为“一……就”；unless意为“除非；如果不”；though意为“尽管”。句意：她妈妈一进入房间，她就停止了说话。
（4）as/ since
as?既可用连续性动词，也可用短暂性动词。
如：Things?are?getting?better?and?better?as?time?goes?on.?随着时间的推移，情况越来越好
since自从……，常用于完成时态
如：It?has?been?three?months?since?he?moved?to?this?city.?自从他搬到这座城市已经三个月了。
例：（2018?贵州黔南)Jack has learned more about teamwork(团队合作) ________ he joined the soccer team.
A. until B. since C. while D. though
B【解析】考查连词。句意：自从杰克加入足球队以来，他更多地学会了团结合作。until直到；since自从…以来；while当…的时候；though虽然。根据前半句用的现在完成时可知用since，故选B.
2.引导条件状语从句的连词有：if，unless，as long as（只要）等
（1）if如果
if引导的条件状语从句用一般现在时，主句用一般将来时。
如：If?it?is?fine?tomorrow,?we?will?go?for?a?picnic.?如果明天天气好，我们就去野炊。
例：(2018·江西)33. —Can students go online during lessons?

A考查连词词义辨析。句意：——学生可以在上课期间上网吗？——____它（上课期间上网）是为了那节课，他们是可以的。if如果；or或者，否则；so所以；but但是。根据语境可知，如果上网是为了那节课，学生就可以上网。故选A。
（2）unless如果不,除非，unless可以转化为“if...not...”结构。
如：He won’t finish the work unless he works hard. 如果他不努力，就不能完成这项工作
例：（2018?四川泸州)Your dream will not come true you keep trying your best.
A. when B. unless C. whether D. because
B 考查状语从句。句意：除非你一直努力，否则你的梦想不会实现。根据句意可知选B项。
【注】 含if/unless引导的条件状语从句的复合句遵循“主将从现”原则。
3.引导目的状语从句的连词：so that(是为了，以便于)，in order that(以便于)等。
（1）so that 为了
如：He got up early so that he could catch the early bus.为了能赶上早班车，他起得很早。
例：(2018·山东东营)—What a mess! The sharing bikes are thrown everywhere.
—Let’s collect and put them in the right place _______ they can be used conveniently.
A. unless B. so that C. because D. so long as
B【解析】考查连词用法辨析。句意：——真的是乱七八糟！共享单车被扔的到处都是。——让我们整理它们，把它们放到正确的位置_______我们可以很便利地使用它们。unless“除非”；so that“目的是，为了”；because“因为”；so long as“只要”。由“What a mess”可知：把单车归还到合适的位置目的是为了方便使用。故选B。

约翰为了买一辆自行车而把钱节省下来。
4.引导原因状语从句的连词：because，as，since等

I?stayed?at?home?because?I?was?ill.?因为生病了，所以我待在家里
例：(2018·湖北黄石) I always get up early on weekdays, ______ I’m afraid I will be late for school.
A. because B. so C. though D. then
A 考查从属连词词义辨析。句意：工作日的时候我总是起得很早，因为我害怕上学迟到。由前后两半句可知，两者是因果关系，故选A。
since既然 表示的原因是对方已知的。
如：Since?he?asks?you,?you’ll?tell?him?why.?既然他问你，你就告诉他为什么。
（3）as 由于，因为 通常置于句首，表示较为明显的原因。

如：He?must?be?ill,?for?he?is?absent.?他肯定生病了，因为他没来。
5.引导结果状语从句：so…that，such…that等。“so…that”与 “such…that”均意为“如此……以至于……”。

A. But B. So C. Although D. And
C【解析】考查连词的用法辨析。句意：尽管史密斯先生学习汉语仅仅半年，但是他能说地很好。由第一句话中“only”可知学习时间短和后边学地好是转折关系，因此用Although翻译为尽管…但是…。But “但是”；So“所以”；And“并且”均与题意不符，故选C
（3）even?though?(if) 即使
如：Even?though/if?we?could?afford?it,?we?wouldn’t?go?abroad?for?our?vacation.?

3.wh－疑问词引导特殊疑问句作宾语从句。
如：He didn't tell me when we should meet again.他没有告诉我什么时候我们应该再见面。
注意：(1)that无实际意义，可省略。
(2)if/whether 意为“是否”。
(3)在if/whether以及wh－疑问词引导的宾语从句中，从句要用陈述语序
考点三 连词易混知识点
1、 because、as、since、for的用法：
（1）because表示原因的语气最强,常表示必然的因果关系,从句一般放在主句后面；另外,回答why的问句只能用because.
（2）as表示一般的因果关系,语气比because弱,说明比较明显的原因,它引导的从句可以放在句首也可以放在句尾。
（3）since(既然)表示对方已经知道、无需加以说明的原因或事实。
（4）for(因为)是并列连词,语气较弱,用来补充说明理由或提供一种解释。
如：He is not at school today because he is seriously ill./ As all of you have got here, now, let’s go to the zoo./ I will ask Lin Tao to go with me since you are very busy. / We must be off now for the match starts at 7：00.
2. when, as, while的用法辨析
（1）when“当……时候”，可以指较短的（一点）时间，也可指一段时间。
如：It was snowing when we got to the station. 我们到达车站时天正在下雪。
（2）as“当……时候”，强调主句和从句的动作同时发生。
如：As I looked back, someone came near. 正当我回头看时，有个人走上前来。
（3）while常表示一段较长时间或一个过程，强调主句谓语动词与从句谓语动词表示的动作同时发生。
如：While I was reading, my mother was washing clothes. 我读书时，我妈妈在洗衣服。
例1：(2018·天津) Tony was drawing a picture_________ I was doing my homework.
A. if B. because C. while D. until
C【解析】考查连词用法辨析。句意：我在做作业的时候，托尼在绘画。由前后两句话的was doing可发现是两个过去进行时的动作，因此可以选用while链接，属于时间状语从句。与 if引导的条件状语从句和 because引导的原因状语从句无关。而until表示“直到”，与原句逻辑关系不符。故选C。
例2： (2018·江苏宿迁) The manager of the hotel was waiting at the gate __________ the guests arrived.
A. while B. when C. unless D. after
B 考查连词辨析。句意：宾馆的经理当客人到来的时候正在大门口等待。when的用法之一：由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时。表示某个动作正在发生时，而另一个动作发生了。故选B。
3. whether与if的用法区别
用作从属连词时.whether和if都意为“是否”。一般情况下，二者可以互换。但以下几种情况中只能用whether：
①与动词不定式连用时。
如:I couldn't decide whether to go.我不确定是否要去
②引导介词的宾语从句时。
如:There has been no news about whether they havefinished their work.
仍然没有他们是否已经完成工作的消息。
③引导主语从句且里于句首时。
如:Whether it is true remains a question.它是真是假还是个问题。
④引导表语从句时。
如:The question is whether it will rain.问题是会不会下雨。
⑤引导同位语从句时。
如：There is a doubt whether he is fit for the job.他是否胜任这份工作还有疑问。
⑥与or not直接连用时。
如：Let me know whetheror not you can win the game.请让我知道你是否能移获胜。
例1：(2018·湖南衡阳)综合填空
Then we check our mobiles from time to time during the meal, to see whether we get “liked” 53 not.
or 考查固定搭配。whether…or not意为“是否”。
例2：（2018·重庆B卷）短文填空
The researchers asked them 77 they napped and for how long.
if/whether 调查者问他们是否小睡，并且睡多久，故填if/whether。
4、as long as,so long as
（1）表示时间，意思是“达之久”。
如：You can keep the book as long as you like。这本书你爱看多久就看多久。
During the holidays，I like to stay in the countryside as long as I can.
假日里，我喜欢呆在乡下，能果多久就呆多久。
（2）表示条件，意思是“只要”。
如:As long as you tell the truth，I’ll try to help you.只要你告诉我实情，我会尽力帮助你。
例：（2018山东菏泽）27. -I really want to pass the exam for further study.
-Believe in yourself, dear! Your dream will come true ____you put your heart into it.
A.even if B. as long as C. as soon as
B【解析】考查连词辨析。句意：—为了继续深造我想通过这次考试。—亲爱的，相信自己！只要你集中精力去做，你的梦想就会变为现实。even if即使；as long as只要；as soon as 一......就.....。分析句意可推知前后存在一种让步关系，“只要你集中精力去做，你的梦想就会变为现实”，用as long as引导，选B。
表示原因，意思是“既然，由于，因为”。
如:So long as the weather is changeable these days,we’d better get in wheat in time.
由于这几天气候变化无常，我们最好及时把麦收割完。

——连词 连词分类
连词主要分为两大类：并列连词和从属连词。
并列连词用来连接平行的词、短语或句子；从属连词是用来引导从句的词。
并列连词按照其在句中的作用可分为表示并列关系、转折关系、选择关系和因果关系的连词。考点一 并列连词一、并列连词 --- 连接具有并列关系的词，短语或句子。 常见的有：
1.表并列关系的and, both…and, not only…but also, neither…nor，as well as（也，和）等。
2.表选择关系的or, either…or等。
3.表转折关系的but, however等。
4.表因果关系的for, so等。考 点 突 破 并列连词的基本用法1.常见的表联合关系的并列连词：
(1)and意为“和，又，而，并且”。
如：I like English and math.我喜欢英语和数学。(2)not only…but also(but as well)…意为“不但……而且……”。
如：Not only my father but also my mother likes watching TV very much.
不但我的爸爸，而且我的妈妈也非常喜欢看电视。
(3)as well as 意为“也”。
如：He needs a knife as well as a piece of paper.
他需要一把小刀，也需要一张纸。
(4)either…or… 意为“或……或……；不是……就是……”。either…or… 连接两个主语时，谓语动词的单复数和其邻近的词保持一致，即由or后面的词而定。
如：Either he or I am going to have a meeting.
要么他，要么我将参加会议。(5)neither…nor… 意为“既不……也不……”。当此词组连接两个主语时，谓语动词的用法和either…or…的用法一样，由nor后面的词而定。
如：Neither the teacher nor the students are happy.
老师和学生都不开心。(6)both…and… 意为“既……又……”，连接两个主语时，谓语动词用复数形式。
如：Both Mary and Lily are from America.
玛丽和莉莉都来自美国。
2.常见的转折连词：but, while(而), yet, however(然而)。如：
He likes sports, but he only watches them on TV.
他喜欢体育，但是只在电视上观看。
My sister was doing her homework while I was playing computer games.
我的妹妹在做作业，而我在玩电脑游戏。注意：however 意为“然而，不过”，可放在句首、句中或句末，不能像 but 那样直接连接两个句子，常用逗号与句子其他部分隔开。
(×)We all tried our best, however we lost the game.
(√)We all tried our best.However, we lost the game.
(√)We all tried our best, but we lost the game.3.常见的选择连词：or, otherwise。
如：Would you like tea or coffee?
你要茶还是咖啡？
Hurry up, otherwise we can't catch the bus.
快点，否则我们赶不上车。
4.常见的因果连词： for, so和therefore等。其中for引导的句子不表示直接原因，而是用来附带解释或说明前一句的情况，只用在句中，前后两个句子用逗号隔开。
如：You'd better put on your sweater, for it's cold outside.
你最好穿上毛衣，外面冷。
My father is waiting for me, so I have to go.
爸爸在等我，所以我要走了。
It is going to rain, therefore we have to put off the match.
要下雨了，因此我们不得不推迟比赛。考点二 从属连词二、从属连词---用来引导从句。常见的从属连词有：
(1)引导时间状语从句的after, before, when, while, as, until, till, since, as soon as等。
(2)引导条件状语从句的if, unless等。
(3)引导原因状语从句的because, as, since等。
(4)引导目的状语从句的so that, in order that等。(5)引导让步状语从句的though, although, even if等。
(6)引导结果状语从句的so that, so…that, such…that等。
(7)引导比较状语从句的than, as…as等。
(8)引导宾语从句的that, if , whether等。引导状语从句的从属连词有：
1.连接时间状语从句的从属连词有：since, until, after, before, when, while, as, as soon as, whenever, ever since等。
如：His father came back home while he was watching TV.
他在看电视的时候，他爸爸回家了。注意：
while引导的时间状语从句，谓语动词必须是延续性动词，且在从句中常用进行时态。
如：
I was doing my homework when my mother came back.
＝While I was doing my homework， my mother came back. 当我正在做家庭作业时，我妈妈回来了。2.连接让步状语从句的从属连词有：although, though, even if, however等。
如：The old man plays sports every morning, although he is over 70 years old.
虽然那个老人70多岁了，但他每天早晨都锻炼身体。
注意：although或though在引导让步状语从句时，主句不可使用转折连词but，但是可以使用yet或still。如:Although she is in poor health，(yet) she works hard.
虽然她的身体不好，但是她工作非常努力。3.连接原因状语从句的从属连词有：as, because, since, now that等。
如：Let's go to a movie，since we are free now.
既然现在我们有时间，那去看电影吧。
because，since，as用法辨析
because表示造成某种情况的直接原因，语气最强，常用来回答由why引导的问句，其从句的位里通常在主句的后面。
He has to leave because it is too late.
因为太晚了，他不得不走。
since语气比as稍强，不表示直接的或根本的原因，而是一种已知的或非常显然的理由，since引导的从句通常位于主句之前。
Since everyone is here, let's start.
既然大家那到齐了，我们就出发吧!as是从属连词，表示原因时，语气最弱，所说的原因比较明显或是已知的事实，它引导的从句一般位于主句之前。
We all like her as she is kind.
我们都喜欢她，因为她善良。4.连接目的状语从句的从属连词有：that, so that, in order that等。
如：Mr.Black ran fast in order that he could catch the train.
布莱克先生为了赶火车而快跑。5.连接条件状语从句的从属连词有：if, unless, once, in case等。
如：Her father won't buy her a present unless she gets good grades.
除非她取得好成绩，不然她爸爸不会给她买礼物的。6.连接结果状语从句的从属连词有：so…that…， such…that…等。
（1）so…that…句型中的so是副词，常常用来修饰形容词或副词，意思是“如此……以至于……”。常用句型结构为：主语＋谓语＋so＋adj./adv.＋that从句或so＋adj.＋a(n)＋单数可数名词＋that从句。如：
He walked so slowly that he fell behind. 他走得如此慢以至于落后了。
It was so fine a day yesterday that we all went out for a picnic. 昨天天气很好，我们都出去野餐了。（2）在such…that…句型中，such修饰名词，意思也是“如此……以至于……”。常用句型结构为：such＋(a/an)＋adj.＋名词＋that从句。如：
He is such a good worker that we all like him.
They are such good workers that we all like them.
It is such fine weather that we all want to go for a picnic. 天气很好，我们都想去野餐。注意：so…that…和such…that…在一些情况下可以通用。但是，当名词前有many，much，few，little(少)等词修饰时，句子中要用so…that…而不能用such…that…。
如：
There are so many cars now that the roads are always crowded. 现在车太多了，所以马路一直拥堵。
He has so little money that he can’t buy the bike.
他的钱太少所以不能买这辆自行车。（3）so…that…引导的结果状语从句为肯定句时，可以改为adj./ adv.＋enough引导的简单句。如：
Jim is so strong that he can carry the big box easily.
＝Jim is strong enough to carry the big box easily.
吉姆如此强壮以至于能轻易地提起那个大箱子。（4）so…that…引导的结果状语从句为否定句时，可以改为too＋adj. /adv. ＋to引导的简单句。
如：
Jim was so tired that he couldn’t walk any longer.
＝Jim was too tired to walk any longer.
吉姆太累了以至于走不动了。小结：状语从句的时态if(如果), as soon as(一……就……), until(直到……才……), when(当……时), before(在……之前), after(在……之后), unless(除非), even if(即使)等词连接时间、条件或让步状语从句时，主句用将来时(有时候是祈使句)，从句用一般现在时表将来。如：We won't go out(主句)if it is rainy tomorrow(从句).
如果明天下雨，我们将不会外出。
As soon as I arrive in Beijing(从句), I will give you a call
(主句).我一到北京，就会给你电话。
She won't go to bed until her mother comes back.
直到她妈妈回来，她才会去睡觉。I won't write to you before you write to me.
