阅读下面选文,回答下列问题。(24分)
心中的芦苇
①记忆中,有一片茂密的芦苇。她像自由的精灵,在远离世俗的淡泊中,独守江畔一方瘠土,筛风弄月,潇洒倜傥。瘦瘦的筋骨把生命的诗意一缕缕地挑亮,密密的芦花像一片片灿烂的微笑,将野地的清苦和宁静浓缩成亘古的沉默,醉倒了金风,醉倒了诗人。仿佛是王维的山水诗,寻不出现实意味和历史痕迹,只有一抹淡远空灵飘浮于烟的高度,还有一分清高,一分落寞,一分不为人知也无意让人知晓的随意与散逸,原始般的单纯和清淡。
②芊芊芦苇,在滩涂上扎根,无拘无束;在纤桥旁摇曳,蓬蓬勃勃。从苍翠的湖绿,渐渐化做凝重的墨色,却依旧亭亭玉立,倩影婆娑。即使翻越季节的山峦,静候白霜降临,那满目的芦花与天上的白云融为一体,绵延至月光不能触及的地方,也依旧洁白光泽,充满蓬勃的张力,然后在冰冷的纯洁里面画上生命的句号。
③这白发苍苍的芦苇,是樵子柴担上悠然飘起的一缕秋光,是村姑眉宇间挥之不去的一抹苍凉的妩媚。像衣香鬃影的女子涉水而来,从古代,从《诗经》,“蒹葭苍苍,白露为霜”遂成千古绝唱。泅流中,弄篱荡舟的少年水手,采兰撷芷、在水一方的窈窕淑女,映衬着茂密的芦苇,成了三千年文明古国最优美的诗行。
④倘若寄身木筏,去溯芦苇之源,那么,你能听到许多滩边涯际拉纤的号子和寨头镇尾浪漫的故事。你也会发现,苍凉凄美的芦花那么轻易就能拨动深藏的沧桑和历史的痛苦。
⑤易水之滨,高渐离击筑,悲凉的旋律中,荆轲告别燕太子丹,踏上刺秦的不归路,他身后的芦花,一定在萧萧寒风中轻扬。乌江之畔,四面楚歌,西楚霸王柔肠寸断,在“虞兮虞兮奈若何”的哀叹声中,虞姬挥动长剑、裙袂飘飘,作最后的生命之舞。在她倒下的地方,雾茫茫,一片绢素,那是一岸的芦花在为这悲怆的诀别飘雪飞霜。汨罗江边,披发行吟的逐臣屈原,掩涕叹息,仰天长问。佞臣专权,楚王昏庸。居庙堂,不能为民解难;谪乡野,不能替君分忧。生命的寂寞郁结于心,奔突于胸,使诗人纵身大江,荡起的涟漪是芦苇悲鸣的泪滴,在湿湿的夜色中流淌。青青的生命的枝叶包裹起千千万万人民的祟敬和思念,投入历史的长河,成为端午节最深沉的纪念。
⑥真正拥有芦苇,是在大学时代。我喜欢在学校后面的江边漫步——那里,茂密的芦苇像无边的绸带,向着远处缓缓铺开。流苏似的芦花,像云,阵阵清香在如纱似雾的月光中弥散。牛乳般的暮霭流动如烟,小鸟在苇丛中呢喃,还有几声蝉鸣,几声虫唱。宁静,温和,洋溢的诗情触手可及。倘是周日,阳光暖暖地流泻,我用苇叶编一只小船,轻轻放人江中,看它悠悠地随风而去。更多的时候,我一卷在握,于芦花下,和屈子同愤,跟太白同醉,与东坡同发少年狂。在绵绵秋雨和茸茸的芦花织成的透明心境中,我读懂了字里行间的辛酸、痛苦、孤独、浓醇、率真和苦涩。人世沧桑和历史悲剧熔铸的惨痛,犹如滴血的利刃,我们的前人把它揉碎了,咽下,宁可肝肠寸断,也要噙着泪带着微笑,轻轻地说,往事如烟啊!
⑦人是孱弱的,就像一根芦苇,但人又是坚强的,从柔弱中焕发出无穷韧性,那种连自己都有可能意识不到的坚韧,陪伴着我们一路向前。法国哲学家帕斯卡尔说:“思想形成人的伟大。人只不过是一根芦苇,是自然界最脆弱的东西,但它是一根能思想的芦苇。”
⑧这根能思想的芦苇,就是你,就是我……
11、作者记忆中的芦苇有怎样的特点?(6分)
12、联系上下文回答,第③自然段中“……成了三千年文明古国最优美的诗行”是什么意思?(6分)
13、第④自然段在文中起了怎样的作用 (4分)
14、像芦苇一样因自身悲凉而引起千万人思念的历史人物很多,你了解的还有哪些 请列出二例并用简要的话概述其事迹或对人物作简要评价。(4分)
15、本文运用了象征的写法,它赋予“芦苇”怎样的意义 (4分)

20、阅读以下文字,给“知识经济”下个定义。(3分)
以前的经济以传统工业为支柱,以稀缺自然资源为主要依托。而知识经济则以高技术产业为第一产业支柱.以智力资源为首要依托。因此,“知识经济”是一种可持续发展的经济,它是一种新型的经济。

A21世纪教育网
The world itself is becoming much smaller by using modern traffic and TV, telephone and so on. Life today is much easier than it was hundreds of years ago, but it has also brought new problems. One of the biggest is pollution. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world..
Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city.
The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.
( )30. Which of the following is NOT TRUE
A. Many countries are making rules to fight pollution.
B. The pollution of the earth grows as fast as the world’s population does.
C. From now on, maybe people should try to go to work by bus or bike instead of car or motorbike. It is helpful to fight against the problem of SO2.
D. The problem of pollution is not so serious because there are so many people
B
People like to say:“The hand that rocks(摇动)the cradle(摇篮)rules the world.”Or they
say:“Behind every successful man,there is a woman.”
Now some women still like making their husbands and sons successful.But some women
want more for themselves.They want to be successful as men.
Today the best jobs are still given to men.Even when women do the same work,they are
often paid less than men.Some women want these things changed.They want to stand beside the men,with the same chances for success.
Now many American women are earning money outside their homes.More than half of the
women at the age of eighteen to sixty-five have good jobs.In general,working women have more education than those who stay at home.
Among women with jobs,eight out of ten drive a car to work,and most of them often spend their holidays away from home.They like traveling by air.Women’s work has made several changes in women’s lives and in men’s lives,too.
But things are quite different from those in the Middle East countries.
In the Middle East countries,women have to stay at home.They look after their families and do all the housework.They can’t find work outside.When they go out in public.they cover their faces with something and walk behind their husbands.
For the past few years the women’s life has been changing in those countries.Many women want to play an active role in the society.Though working gives them few chances of getting married,many men still want to marry them in the old ways.
( )31.More and more women want to get jobs because .
A.they don’t want to stand behind their husbands in the street
B.they think they are more important than men
C.they think they are as important as men
D.housework troubles them too much
( )32.Some women are still badly paid .

Everyone needs friends. Friends bring us happiness and hope in our lives. But the ability to make friends changes from person to person. To some people, making friends is easy, and to others it’s very difficult.[来源:21世纪教育网]
Making friends is a skill, and the first thing is to know how to get on with others.
If you have trouble in making friends, maybe I can tell you how to do it.
Realize your own good points. You have skills and talents(才能) that others will like.
Believe that you are a good person and have something nice to share with others.
Be humourous. Learn to laugh at yourself and your weakness. Remember to smile at others.
Respect the others. Everyone has his own idea. Learn how to listen to others’ ideas without trying to make them accept yours.
Be kind. If you are kind to others, they will usually be kind to you. There are hundreds of little things you can do to show your kindness. Open the door for someone. Wave to a friend and so on.
Don’t complain(抱怨). Learn to accept what you can’t change, and work hard to change what you can. No one is willing to hear your complaints all the time.
Never give up. Even if you are faced with some closed-minded people, never give up. And try to find someone who will understand you.
( )36. Why do we need friends according to the passage
A Friends can do everything for us. B Friends can bring us happiness.
C Friends accept our ideas all the time. D Without friends, we could not live.
A Respect others. B Complain. C Give up. D Laugh at them

Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals, and fish. The lake water is polluted. It is in a colour of dirty brown, and it is filled with strange plants.
How did this happen First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all round Lake Ponkapog, so the rainwater was clean.
Now there are many homes around the lake. People often use the chemicals (化学制品)in their gardens. They use other chemicals inside their houses for cleaning and killing insects. There are also many businesses. Businesses use chemicals in their machines of shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from home and businesses and then carries them into the lake . They pollute the water and kill the animals.
Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats(汽船). But oil and gas from boats often get into the lake. So more bad chemicals go into the water this way.
People in Hartwell are worried . They love their lake and want to save it. Will it be possible A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at other chemicals on the ground. And they mustn’t use motorboats any more on the lake. All these may change people’s lives. Only then can Lake Ponkapog be a beautiful, clean lake again.
( )41. In the past, the water in Lake Ponkapog was made clean by ________.
A. forests B. rain C. birds D. fish
( )42. Chemicals from homes and businesses _________.
A. are always clean B. can help the animals
C. are good for the lake D. get into the rainwater
( )43. Cleaner rainwater will mean _________ .
A. more boats on the lake B. more dirty things in the lake
C. a cleaner lake D. a dirty lake
( )44. To save Lake Ponkapog, people need to ________.
A. be more careful about chemicals B. use the water
C. grow fewer plants in the gardens D. use more motorboats on the lake
( )45. The passage is about ________.
A. boats on the Lake Pankapog B. why the water is dirty in Lake Ponkapog
4、 C. clean rainwater D. dirty lakes
