賓語(yǔ)從句中考考點(diǎn)點(diǎn)擊
賓語(yǔ)從句在初中英語(yǔ)語(yǔ)法中有著相當(dāng)重要的地位,幾乎每年的中考都有對(duì)賓語(yǔ)從句不同角度的考查。筆者認(rèn)真研讀了近年來有關(guān)賓語(yǔ)從句的中考題,發(fā)現(xiàn)其考查的重點(diǎn)一般都集中在以下幾個(gè)方面:
一、連接詞
賓語(yǔ)從句的連接詞分為三類:
1.引導(dǎo)陳述句用that(在口語(yǔ)或非正式文體中常常省略)。
2.引導(dǎo)一般疑問句用if或whether。
注意:下列幾種情況通常使用whether:
(1)在具有選擇意義又有or或or not時(shí),尤其是直接與or not連用時(shí),往往用whether;
。2)在介詞之后用whether;
。3)在不定式前用whether等。
3.引導(dǎo)特殊疑問句,只需用原來的特殊疑問詞。
中考題例:
We'd like to know ___________ or not.(2004年山東濰坊)
A.whether will the sports meeting come
B.if will the sports meeting come
C.whether the sports meeting will come
D.if the sports meeting will come
答案與解析:答案為C項(xiàng)。題干中出現(xiàn)了or not,所以連接賓語(yǔ)從句的引導(dǎo)詞要用whether,故選C項(xiàng)。
二、語(yǔ)序
在含賓語(yǔ)從句的復(fù)合句中,不管主句是陳述句還是疑問句,從句一律是用“連接詞+陳述句語(yǔ)序”,其標(biāo)點(diǎn)符號(hào)由主句來決定。
中考題例:
- Excuse me,could you tell me ___________?
- Certainly.It's over there along the street on the left.(2005年吉林)
A.where the People's Park is
B.where is the People's Park
C.the People's Park is where
D.the People's Park where is
答案與解析:答案為A項(xiàng)。賓語(yǔ)從句一律使用陳述句語(yǔ)序,故選A項(xiàng)。

第三部分:閱讀理解(共20小題;每小題2分,滿分40分)
閱讀下列短文,從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
Looking back on my childhood, I am convinced that naturalists are born and not made.Although we were all brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects.Unlike them, I had no ear for music and languages.I was not an early reader and I could not do mental arithmetic.
Before World War I we spent our summer holidays in Hungary.I have only the dim memory of the house we lived in, of my room and my toys.Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door.But I do have a clear memory of the dogs, the farm animals, the local birds, and above all, the insects.
I am a naturalist, not a scientist.I have a strong love of the natural world and my enthusiasm had led me into varied investigations.I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries.Then something happens that brings these observations together in my conscious mind.Suddenly you fancy you see the answer to the riddle, because it all seems to fit together.This has resulted in my publishing 300 papers and books, which some might honor with the title of scientific research.
But curiosity, a keen eye, a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack.A scientist, up to a certain point, can be made.A naturalist is born.If you can combine the two, you get the best of both worlds.
61.The first paragraph tells us the author_____.
A.was interested in flowers and insects in his childhood
B.lost his hearing when he was a child
C.didn’t like his brothers and sisters
D.was born to a naturalist’s family
62.The author can’t remember his relatives clearly because_____.
A.he didn’t live very long with them
B.the family was extremely very large
C.he was too young when he lived with them
D.he was fully occupied with observing nature
63.It can be inferred from the passage that the author was_____.
A.a(chǎn) scientist as well as a naturalist B.a(chǎn) naturalist but not a scientist
C.no more than a born naturalist D.first of all a scientist
64.The author says that he is a naturalist rather than a scientist probably because he thinks he_____.
A.has a great deal of trouble doing mental arithmetic
B.lacks some of the qualities required of a scientist
C.just reads about other people’s observations and discoveries
D.comes up with solutions in a most natural way
B

If women are mercilessly exploited year after year, they have only themselves to blame, because they tremble at the thought of being seen in public in clothes that are out of fashion.They are always taken advantage of by the designers and the big stores.Clothes which have been worn only a few times have to be put aside because of the change of fashion.When you come to think of it, only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear.
Changing fashion is nothing more than the intentional creation of waste.Many women spend vast sums of money each year to replace clothes that have hardly been worn.Women who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have.Skirts are lengthened or shortened; necklines are lowered or raised, and so on.
No one can claim that the fashion industry contributes anything really important to society.Fashion designers are rarely concerned with vital things like warmth, comfort and durability(耐用) .They are only interested in outward appearance and they take advantage of the fact that women will put up with any amount of discomfort, as long as they look right.There can hardly be a man who hasn’t sometimes in his life smiled at the sight of a woman shaking in a thin dress on a winter day, or delicately picking her way through deep snow in high-heeled shoes.
When comparing men and women in the matter of fashion, the conclusions to be drawn are obvious.Does the constantly changing fashion of women’s clothes, one wonders, reflect basic qualities of instability? Men are too clever to let themselves be cheated by fashion designers.Do their unchanged styles of dress reflect basic qualities of stability and reliability? That is for you to decide.
69.Designers and big stores always make money_____.
A.by mercilessly exploiting women workers in the clothing industry
B.because they are capable of predicting the new fashion
C.by constantly changing the fashion in women’s clothing
D.because they always improve the quality of women’s clothing
70.To the writer, the fact that women change their old-fashioned dress is seen as_____.
A.a(chǎn) quality of instability B.a(chǎn) waste of time and money
C.a(chǎn)n expression of taste D.a(chǎn)n expression of creativity
71.The writer would be less critical if fashion designers placed more stress on the_____.
A.cost B.a(chǎn)ppearance C.comfort D.suitability
72.By saying “ the conclusions to be drawn are obvious”, the writer means that_____.
A.women’s changeableness in their choice of clothing was often laughed at
B.women are better able to put up with discomfort
C.men are also exploited greatly by fashion designers
D.men are more reasonable in the matter of fashion
D
Do you want to live another 100 years or more? Some experts say that scientific advances will
one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future.“ I think by 2075 we will see it and that’s a conservative estimate.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(納米技術(shù)) make it likely that humans will live in the future beyond what has been possible in the past.“ There is a great push so that people can live from 120 to 180 years,” he said.“ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years.Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live.“ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center.“ At present people who could get to that point are not in good health at all.”
73.By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A.they believe that there is no limit of living
B.they are sure to find the truth about long living
C.they have got some ideas about living forever
D.they are able to make people live past the present life span
74.Donald Louria’s attitude toward long living is that_____.
A.people can live from 120 to 180
B.it is still doubtful how long humans can live
C.the human body is designed to last about 120 years
D.it is possible for humans to live longer in the future
75.The underlined “ it” (Para.4) refers to_____.
A.a(chǎn) great push
B.the idea of living beyond the present life span
C.the idea of living from 200 to 300
D.the conservative estimate
76.What would be the best title for this text?
A.Living longer or not
B.Science, technology and long living
C.No limit for human life
D.Healthy lifestyle and long living

I am a good mother to three children.I have tried never to let my profession stand in the way of being a good parent.
I no longer consider myself the center of the universe.I show up.I listen.I try to laugh.I am a good friend to my husband.I have tried to make marriage vows mean what they say.I am a good friend to my friends, and they to me.Without them, there would be nothing to say to you today.
So here’s what I wanted to tell you today: Get a life.A real life, not a desire of the next promotion, the bigger pay-check….
Get a life in which you are not alone.Find people you love, and who love you.And remember that love is not leisure, it is work.Pick up the phone.Send an e-mail.Write a letter.And realize that life is the best thing and that you have no business taking it for granted.
It is so easy to waste our lives, our days, our hours, and our minutes.It is so easy to exist instead of to live.I learned to live many years ago.Something really, really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all.And what I learned from it is what , today, seems to be the hardest lesson of all.
I learned to love the journey, not the destination.I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally.And I tried to do that, in part, by telling others what I had learned.
By telling them this: Read in the backyard with the sun on your face.Learn to be happy.And think of life as a deadly illness, because if you do, you will live it with joy and passion as it ought to be lived.
77.It can be inferred from the passage that_____.
A.the author is a success in personal life
B.the author didn’t try her best to work well
C.the author spent all her time caring for her children
D.the author likes travelling very much
78.How did the author form her view of life?
A.Through social experience. B.By learning from her friends.
C.Through an unfortunate experience D.From her children and husband.
79.By the underlined sentence “ It is so easy to exist instead of to live” in the fifth paragraph, the author really means that people tend to_____.
A.make a living rather than live a real life
B.work rather than enjoy life
C.waste a lot in life
D.forget the most important lessons in life
80.What’s the author’s attitude towards work?
A.Do it well to serve others.
B.Earn enough money to make life better.
C.Try your best to get higher position and pay.
D.Don’t let it affect your real life.

How often one hears children wishing they were grown up, and old people wishing they were young again. Each age has its pleasures and its pains, and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets.
Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. in addition, life is always presenting new things to the child-things that have lost their interest for older people because they are too well-known. But a child has his parents, he is not so free to do what he wishes to do; he is continually being told not to do things or being punished for what he has done wrong. When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.
64. According to the second paragraph, the writer thinks that _______.
A. life for a child is comparatively easy
B. a child is always loved whatever he does
C. if much is given to a child, he must do something in return
D. only children are interested in life
65. Which of the following statements is NOT true according to the passage?
A. People are often satisfied with their life.
B. Life is less interesting for old people.
C. Adults are freer to do what they want to do.
D. Adults should no longer rely on others.
66. The main idea of the passage is _________.
A. life is not enjoyable since each age has some pains
B. young men can have the greatest happiness if they work hard
C. childhood is the move enjoyable time in one’s life
D. one is the happiest if he can make good use of each age in his life
67. The paragraph following this passage will most probably discuss _________.
A. examples of successful young men
B. how to build up one’s position in society
C. joys and pains of old people
D. what to do when one has problems in life
D
“It hurts me more than you”, and “This is for your own good”―these are the statements my mother used to make years ago when I had to learn Latin, clean my room, stay home and do homework.
That was before we entered the permissive period in education in which we decided it was all right not to push our children to achieve their best in school. The schools and the educators made it easy for us. They taught that it was all right to be parents who take a let-alone policy. We stopped making our children do homework. We gave them calculators, turned on the television, left the teaching to the teachers and went on vacation.
Now teachers, faced with children who have been developing at their own pace for the past 15 years, are realizing we’ve made a terrible mistake. One such teacher is Sharon Klompus who says of her students―“so passive”―and wonders what has happened. Nothing is demanded of them, she believes. Television, says Klompus, contributes to children’ s passivity. “We’ re talking about a generation of kids who’ ve never been hurt or hungry. They have learned somebody will always do it for them, instead of saying ‘go and look it up’, you tell them the answer. It takes greater energy to say no to a kid.”
Yes, it does. It takes energy and it takes work. It’ s time for parents to end their vacation and come back to work. It’ s time to take the car away, to turn the TV off, to tell them it hurts you more than them but it’ s for their own good. It’s s time to start telling them no again.
68.Children are becoming more inactive in study because ____.
A. they watch TV too often B. they have done too much homework
C. they have to fulfil too many duties D. teachers are too strict with them
69.We learn from the passage that the author’s mother used to lay emphasis on_____.
A. learning Latin B. discipline
C. natural development D. education at school
70.By“permissive period in education”(L.1,Para.2)the author means a time ___.
A. when children are allowed to do what they wish to
B. when everything can be taught at school
C. when every child can be educated
D. when children are permitted to receive education
71. The main idea of the passage is that____ .
A. parents should leave their children alone
B. kids should have more activities at school
C. it’s time to be more strict with our kids
D. parents should always set a good example to their kids

Advertising is a highly developed twentieth-century industry. The development of radio, television, cinema, magazines and newspapers has gone hand in hand with the development of advertising. Why is advertising so popular? Is it a waste of money? It has been proved again and again that ?repeated advertising increases product sales. Since it increases production, the price can be reduced. Therefore advertising, instead of making a product more expensive, makes it cheaper.
Advertising is now a scientific business. Once managers would say jokingly, " I know that half of what I spend on advertising is wasted, but I don't know which half." Now, all parts of an advertising programme are properly measured and researched.
What makes a good advertisement? There have been major changes in advertising in the past sixty years.. People read advertisements partly for information and partly for pleasure. Today's advertisements often start with a question, or a puzzle, with the purpose of attracting the reader's attention. Of course, most advertisements contain information. But this is usually contained in a text that is interesting and often funny. Humour is very important. Sometimes advertisements tell a story, or the story may be continued over a number of advertisements. However, there is a danger in this. It is possible that the reader or viewer will remember the advertisement but not the name of the product.
72. The purpose of advertising is ____.
A. to increase product sales
B. to make a product much better
C. to spend more money
D. to reduce the production
73. Which of the following can be used in place of the underlined phrase "hand in hand" ?
A. Here and there. B. Again and again.
C. As usual. D. At the same time.
74. What is meant by what managers said in the second paragraph?
A. A11 the money on advertising was wasted.
B. Not all the advertisements were well designed.
C.A11 the managers knew about advertising then.
D. Managers spent no money on advertising.
75. What does the writer think of advertising?
A. Useless. B. Unnecessary. C. Important. D. Wasteful.

(本試卷分第Ⅰ卷和第Ⅱ卷兩部分,共150分,考試時(shí)間150分鐘。)
第Ⅰ卷(選擇題 共33分)
課題1、空氣習(xí)題課精講精練
【例題精講】
【例題1】空氣成分按體積計(jì)算,含量約占21%的氣體是( )
A、氧氣 B、 氮?dú)?nbsp; C、 二氧化碳 D、 稀有氣體
【解析】空氣中氮?dú)饧s占78%,氧氣約占21%,稀有氣體約占0、94%,二氧化碳約占0、03%,其他雜質(zhì)和氣體占0、03%。這些指的都是體積分?jǐn)?shù)。
【答案】A
【例題2】在充滿空氣的集氣瓶中(瓶底鋪一層細(xì)沙),放入一小塊白磷,用灼熱的鐵絲把白磷點(diǎn)燃并立即把瓶蓋塞緊,當(dāng)白磷燃燒停止,集氣瓶的溫度恢復(fù)到室溫時(shí),打開瓶塞,感到比平時(shí)費(fèi)力多了,這是為什么?
【解析】白磷燃燒前,瓶?jī)?nèi)外的壓強(qiáng)相等,打開瓶蓋不困難。白磷燃燒消耗了瓶中的氧氣,使瓶中產(chǎn)生了負(fù)壓,即瓶中的壓強(qiáng)小于瓶外的壓強(qiáng),所以打開瓶塞時(shí)感到比平時(shí)費(fèi)力多了。
【答案】燃燒后瓶?jī)?nèi)壓強(qiáng)小于瓶外的壓強(qiáng)。
【例題3】空氣質(zhì)量日?qǐng)?bào)重要內(nèi)容包括:首要污染物、空氣污染指數(shù)和空氣質(zhì)量級(jí)別。

(1)上述城市中容易出現(xiàn)酸雨的城市是 ;
(2)請(qǐng)根據(jù)表一和表二中的內(nèi)容,確定當(dāng)日天津的空氣質(zhì)量級(jí)別,并填在表二的空格內(nèi)。
【解析】本題的關(guān)鍵是正確而有效地利用題中提供的信息,從中找出判斷空氣質(zhì)量好壞的方法和標(biāo)準(zhǔn)。然后結(jié)合具體的問題做出合理的分析判斷。注意并非空氣污染指數(shù)越高,越容易出現(xiàn)酸雨。酸雨的形成主要與大氣污染物二氧化硫有關(guān),因此題中容易出現(xiàn)酸雨的城市不是上海,而是昆明。
【答案】(1)昆明 (2)Ⅱ良
【例題4】
(1)市場(chǎng)上銷售的香腸、鹽水鴨、榨菜、豆腐干等食品,常采用真空包裝、真空包裝的目的是除去空氣,使大多數(shù)微生物因缺少 氣而受到抑制,停止繁殖,同時(shí)防止食品發(fā)生緩慢氧化而變質(zhì)。
(2)茶葉、肉松、膨化食品等常采用真空充氣包裝,即將食品裝入包裝袋,抽出包裝袋內(nèi)空氣,再充入防止食品變質(zhì)的氣體,然后封口、真空充氣包裝能使食品保持原有的色、香、味及營(yíng)養(yǎng)價(jià)值,防止食品受壓而破碎變形。
【提出問題】充入食品包裝袋中的氣體是什么?
【猜想與驗(yàn)證】可能是N2,實(shí)驗(yàn)初步驗(yàn)證的方法及現(xiàn)象是 。充入的氣體還可能是:① ;② ……
【解析】本題考查學(xué)生學(xué)習(xí)和利用信息資料解決問題的能力,同時(shí)培養(yǎng)學(xué)生開放性思維主動(dòng)進(jìn)行問題探究的意識(shí)和能力。解題的關(guān)鍵是認(rèn)真閱題,理解并利用題中的信息,結(jié)合空氣組成。真空包裝和真空充氣包裝食品的共同之處都是使食品袋內(nèi)缺少氧氣和水分,這樣微生物生理活動(dòng)受到抑制,另外使食品本身不能發(fā)生緩慢氧化而變質(zhì),從而延長(zhǎng)了保質(zhì)期。真空充氣包裝顯然不是真空,但充入的氣體應(yīng)具備不供給呼吸,化學(xué)性質(zhì)穩(wěn)定,不會(huì)帶來危害,又比較容易獲得等特點(diǎn)。因此猜想應(yīng)朝這方面進(jìn)行,這類常見的氣體有氮?dú)夂投趸,稀有氣體獲得較難,成本高,不考慮。這樣猜想驗(yàn)證實(shí)施,就利用氮?dú)夂投趸蓟瘜W(xué)性質(zhì)進(jìn)行比較完成。
【答案】
(1)氧
(2)將燃著的木條伸入該氣體,火焰熄滅,然后將該氣體通入澄清石灰水中,石灰水變渾濁。①氮?dú)猗诘獨(dú)夂投趸?/p>

(2)1/5,不能助燃、不溶于水(或化學(xué)性質(zhì)穩(wěn)定),不能,碳粉燃燒生成二氧化碳?xì)怏w,瓶?jī)?nèi)氣體體積無明顯的變化,不能形成壓強(qiáng)差。
【中考鏈接答案】
1、【解析】解題的關(guān)鍵是了解人類面臨的空氣污染主要有粉塵和有害氣體(包括CO、SO2、NO2等氮氧化合物)。對(duì)空氣污染因素種類很多,要明確和層次分明。一定要注意CO2雖然在空氣的含量過多會(huì)引起溫室效應(yīng),但它不是空氣污染物。另外此題要解答的是氣體污染物,而不是固體懸浮物―煙塵。
【答案】 CO、SO2、NO2等氮氧化合物中的一種或名稱。
2、【解析】氫氧化鈉可以吸收二氧化碳?xì)怏w,濃硫酸可以吸水,所以B、C的植物生長(zhǎng)的不好,而D只有水,植物生長(zhǎng)得也不會(huì)很好,A中雪碧飲料既能產(chǎn)生二氧化碳又有水,所以A數(shù)天后植物生長(zhǎng)最茂盛。
3、【解析】大理石不溶于水,但圖示告訴我們她溶于酸,這樣可知道大理石雕像被腐蝕應(yīng)該是空氣污染后產(chǎn)生的酸雨所造成的。聯(lián)系空氣污染會(huì)引起酸雨的是SO2和NO2,這些氣體來自于工廠的廢氣和燃燒含硫、氮的化石燃料燃燒所至。這樣就找到了解題的方向。
【答案】此圖反映出環(huán)境污染問題是:酸雨問題。
建議:限制含硫煤的使用;化工廠尾氣處理達(dá)標(biāo)后排放;使用綠色能源;汽車尾氣經(jīng)處理后排放。
4、【解析】檢驗(yàn)裝置的氣密性必須要形成封閉體系,所以要往B中加水,使A、B液面保持水平,蓋緊 A的密封蓋,再向B中加水,使B中的液面高于A,一段時(shí)間后B中液面不下降,則氣密性好。要測(cè)定空氣中氧氣的體積分?jǐn)?shù),應(yīng)選擇能和氧氣反應(yīng),產(chǎn)生固體的物質(zhì),木炭和氧氣生成二氧化碳?xì)怏w,所以不能選擇。因空氣的氧氣約占1/5,反應(yīng)后裝置A體積縮小1/5即3mL,為12mL,現(xiàn)為11mL,故實(shí)驗(yàn)結(jié)果比理論值偏大。若要用木炭粉代替銅粉,要把水換成能吸收二氧化碳的試劑即石灰水或氫氧化鈉溶液。
【答案】
(1)往B中加水,使A、B液面保持水平,蓋緊 A的密封蓋,再向B中加水,使B中的液面高于A,一段時(shí)間后B中液面不下降,則氣密性好。(或往B中加水,使A、B液面保持水平,蓋緊A的密封蓋,再用手捂住A的外壁,若B中的液面上升,則氣密性好。)
(2)B
(3)12 ,偏大
(4)澄清石灰水或氫氧化鈉溶液, 用石灰水或氫氧化鈉吸收反應(yīng)生成的二氧化碳。
