九年级英语下专题复习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…
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:
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。
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]
1.I bought my son a birthday present,______ he liked it very much.
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。
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。
[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. (√)
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.
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.
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。
[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.
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。
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。
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?
—I’m afraid not ________you have a ticket,because I have only one.
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_______.
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。
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)
2.The FIFA World Cup is______ fantastic that a lot of people in the world are crazy(疯狂的) about it.
A.such B.so C.very (哈尔滨)
[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)
[答案解析]1.A。分析语境,对话前句意为:我不能肯定其他行星上是否存在生命。whether充当引导词,表示“是否”。
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。
