专题复习6连词教案
【教学目标】
1. 要求学生掌握并列连词and, but, or, so等的主要用法；
2. 学生能熟练运用常用的从属连词的基本用法。
【教学重点难点】
1. 并列连词and, but, or, so, for, both…and…,either…or…,neither…nor…,not only…but also…21·cn·jy·com
2. 从属连词that, if, whether, how, where, why, when, while, before, after, as soon as, until, because, since, unless, though, too…to, so that的用法。
【知识梳理】
考点一：表示联合关系的并列连词
表示联合关系的并列连词主要有and，both…and…，not only…but also…，as well
as等。
[难点突破]
1．both...and…，not only…but also…连接两个成分，充当句子的主语时，谓语动词要用复数形式。例如：2·1·c·n·j·y
Not only he but also his sister are good at dancing．他和他的妹妹都擅长跳舞。
Both Mr. Wu and his wife have gone to England for a visit．吴先生和他的妻子都去了英国旅游。【来源：21cnj*y.co*m】
2．as well as也可用来表示并列关系，意为“也、又、还”，该词组连接句子的主语时，谓语动词在人称和数上要与as well as前面的名词或代词保持一致。换句话说，as well as前的成分才是句子的真正主语，决定了句子的谓语形式。例如：
Mike as well as his parents is good at playing basketball．
迈克和他的父母都擅长打篮球。
The twins as well as my sister are always ready to help the others．
双胞胎和我妹妹都乐于助人。
[真题回顾]

A．or B．but C．and D．so (济宁)
2．—Who can tell me something about London?
—________ Lucy _______ Mike are from England．You can ask either of them．
A．Only；except B．Either；or C．Neither；nor D．Both；and
(赣州)
[答案解析] 1．C。因为“我买给儿子生日这礼物”和儿子“非常喜欢礼物”意义顺接。故本题填and。21cnjy.com
2．D。解答本题要从答语中的You can ask either of them．入手，因为Lucy和Mike两人都来自英国，所以他们当中的任何一人都能说出有关伦敦的一些信息。
考点二：表示转折关系的并列连词
表示转折关系的并列连词主要有but，however，yet (但是)，while (而)等，这些词连接的双方意义构成对比，关系互为转折。21教育网
[难点突破]
用英语表示“虽然……，但是……时，容易受汉语中并列词总是成双出现的影响，而错误地在一个句子之中重复使用though／although和but。例如：
Although the boy is only six years old, but he knows a lot.(×)
Although the boy is only six years old, he knows a lot. (√)21教育名师原创作品
The boy is only six years old, but he knows a lot. (√)
[真题回顾]
—Wang Jinquan，a teacher from Qichun，has supposed many poor students to college．
—_______ he himself lives a plain (朴素的) life.
A．So B．But C．Because D．Though (黄冈)
[答案解析]B。Wang Jinquan “支助多位贫困生上大学”与他“过朴素生活”之间是转折关系。
考点三：表示选择关系的并列连词
表示选择关系的并列连词主要有：or，either…or…，neither…nor…等。
[难点突破]
1．or用来引起相反的情况，意为“否则”，通常用于“祈使句+or+陈述句”句式中。这种句式通常可以改为意义相当的条件状语从句。例如：
Harry up，or you’ll be late for school．赶快，否则你上学将会迟到。
If you don’t hurry up，you’ll be late for school. 如果你不赶快，上学就会迟到。
2．either…or…和neither…nor…这两个词组连接句子的主语时，谓语动词在人称和数上要和or及nor后的主语保持一致，这就是英语主谓关系中的就近原则。例如：Either you or he is right. 或者你对，或者他对。
Neither I nor my brother is good at playing the guitar. 21世纪教育网版权所有
我和我弟弟都不擅长弹吉他。
[真题回顾]
1．Be careful，_______you’ll miss the right answer.
A．and B．or C．but D．so (2010年陕西卷)
2．—I would like you to talk about the Great Wall． (2010年常州卷)
—I’m sorry，but______ Jack ______I have been there．
A．either；or B．neither；nor C．both；and D．not only；but also
3. I could speak ______Japanese ______Chinese，so I had to talk with him in English．
A．not only；but also B．both；and C．neither；nor D．either；or
(辽宁)
[答案解析11．B。本题属“祈使句+or+简单句”句式。be careful和you’ll miss the right answer情况相反，所填or的意思为“否则”。
2．B。由答语中的I’m sorry可知我和Jack都没去过长城。
3．C。由so I had to talk with him in English 可知“我既不会说日语，也不会说汉语”，故选C。
考点四：表示因果关系的并列连词
表示因果关系最主要的并列连词是because和so。
[难点突破]
because和so用来表因果关系时，两者不能同时用于一句之中，只能择一使用。例如：Because he was ill，so he didn’t go to school. (×)
Because he was ill，he didn’t go to school.(√)
He was ill，so he didn’t go to school.(√)
[真题回顾]
She had a stomachache _______ she ate something bad.21·世纪*教育网
A．so B．because C．or D．although (定西)
[答案解析]B。“她胃痛”是因为“她吃了变质的东西”。
考点五：引导时间状语从句的从属连词
引导时间状语从句的从属连词主要有when，while，before，after，as soon as，until，since等。2-1-c-n-j-y
[难点突破]
在时间状语从句中，如果主句叙述的是尚未发生的动作，从句须用一般现在时表示动作将要发生。例如：
I will tell him the good news as soon as he comes back．www.21-cn-jy.com
他一回来，我就会告诉他这个好消息。
She won’t be back here to visit you until she hears from you．
她直到收到你的信后才会回这里来看你。
[真题回顾]
1．I was listening to music _______ my English teacher came in．
A．until B．while C．since D．when (日照)
2．I didn’t go to bed _______ my mother came back late last night．
A．so B．until C．though (贵阳)
[答案解析1. D。填入空格的when是“当……时”的意思，全句意思为：当英语老师进来时，我正在听音乐。【来源：21·世纪·教育·网】
2．B。not…until…是固定搭配，意为“直到……才……”，填入正确答案后全句意思为：昨晚直到我妈妈很晚回家后我才去睡觉。21*cnjy*com
考点六：引导条件状语从句的从属连词
引导条件状语从句最主要的从属连词是if和unless，前者意为“如果”，后者意为“除非”。
[难点突破]
在条件状语从句中，如果主句是祈使句或是叙述尚未发生的动作，从句须用一般现在时表示动作将要发生。例如：
Don’t eat the food on the table unless you are hungry．
不要吃桌子上的食物，除非你饿了。
We shall go hiking if it doesn’t rain tomorrow. 如果明天不下雨，我们将去远足。
[真题回顾] 1．—May I go to the concert with you?

A．since B．if C．unless D．though (铜仁)
2．—What are you going to do this afternoon?
—We are going to have a football match if it_______.www-2-1-cnjy-com
A．will rain B．rained C．doesn’t rain (长沙)
[答案解析)1．C。“你有票”是“你和我去看演出”的条件。本题意为：恐怕你不能和我一起看音乐会，除非你有票，因为我只有一张票。【出处：21教育名师】
2．C。答语是一条件状语从句，主句用了一般将来时，从句须用一般现在时表示动作将要发生。
考点七：引导目的状语从句的从属连词
引导目的状语从句最主要的从属连词是so that(以便)和in order to (为了)。
[难点突破]…和too…to…两词组引导的结果目的状语从句可以互相转化，构成同义句。例如：He gets up early so that he can get the Christmas present first.
=In order to get the Christmas present first，he gets up early.
为了能第一个得到圣诞礼物，他一早起来。
[真题回顾] The teacher speaks very loudly _______ all the students can hear her．
A．so that B．because C．since D．when (广州)
[答案解析]A。“老师大声说话”的目的是为了“所有的学生都能听见她说话”。
考点八：引导结果状语从句的从属连词
引导结果状语从句最主要的从属连词有：so…that…(如此……以致……)和too…to…(太……而不能……)。
[难点突破] so…that...和too…to…两词组引导的结果状语从句可以互相转化，构成同义句。例如：He is so excited that he can’t say a word．他如此激动以至于一句话也说不出来。
=He is too excited to say a word．他太激动而说不出一句话。
[真题回顾]
1. I often laugh when I see my grandma learning pop songs．But she says，“One is never _______old to learn.”
A．too B．so C．very D．quite (河南)

[答案解析] 1. A。奶奶说的话One is never too old to learn.的意思是“活到老，学到老”。
2. B。“世界杯有趣”以至于“世界上很多人为此疯狂”。
考点九：引导宾语从句的从属连词
引导宾语从句最主要的从属连词是that，if, whether，what，when，where等。
[难点突破]
宾语从句的引导词是由从句的句子种类决定的。若从句为陈述句，引导词为that，that无实际意义，在口语和非正式文体中常省略；若从句为一般疑问句，引导词为if或whether；若从句为特殊疑问句，引导词为疑问句原来的特殊疑问词。
[真题回顾]1. —I’m not sure________ there are living things on other planets or not．
—Even scientists aren’t sure about it.
A．whether B．where C．why (福州)
2．—Do you know_________ the girl in red is? —I’m not sure．Maybe a teacher．
A．when B．how C．where D．what (南京)

2．D。本题要紧抓住答语中的Maybe a teacher．来分析语境，由此可推断问句所询问的是穿红衣服女子的职业。【版权所有：21教育】
