But actually the umbrella was not invented as protection against rain. Its first use was as a shade (遮蔽) against the sun.Nobody knows who first invented it, but the umbrella was used in very ancient (古老的) times. Probably the first to use it were the Chinese, back in the eleventh century B.C.We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honour and power. In the Far East in ancient times, the umbrella was allowed to be used only by royal (皇室的) people or by those in high office.In Europe, The Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans.During the middle ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power.Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn’t until the twentieth century that women’s umbrellas began to be made in all kinds of colours.25. The first use of umbrellas was as __________.A. protection against rainB. protection against the sunC. a symbol of powerD. a symbol of honour26. According to the passage, the umbrella was probably first invented __________.A. in ancient ChinaB. in ancient EgyptC. in ancient GreeceD. in ancient Rome27. According to the passage, which of the following is NOT true?A. The umbrella didn’t change much in style in the 18th century.B. No one really knows who was the inventor of the umbrella.C. Once not everyone was allowed to use umbrellas.D. women’s umbrellas were ma de in all kinds of colours in the beginning.BIn Britain you may often hear “Drop in any time” or “Come to see me soon”, but you can’t really do that. People just say those things to make you feel welcome. It is better to telephone before visiting som eone at home. If you receive a written invitation to an event that says “RSVP”, you should reply to let the person who sent the invitation know whether or not you plan to go.Y ou should never accept an invitation unless you really plan to go. You may refuse by saying, “Thank you for inviting me, but I will not be able to come.” If, after accepting, you are unable to go, be sure to tell those who are expecting you as soon as possible that you will not be there. Although it is not necessarily expected that you give a gift to your host, it is considered polite to do so, especially if you have been invited for a meal. Flowers, chocolate, or a small gift are all appropriate (合适的). A thank-you note or telephone call after the visit is also considered polite and is an appropriate way to express your thanks for the invitation.28. What does the underlined word “RSVP” probably mean in Chinese?A. 请自便B. 请回复C. 请审阅D. 请来访29. What should you do if your British friend sends you an invitation but you do not want to go?A. Do not give him or her an answer.B. Tell another friend to go instead of you.C. Tell him or her that you can’t be there for some reason.D. Tell him or her that you don’t want to go there.30. Which of the following is considered impolite in Britain?A. Buy small presents when invited.B. Refuse the invitation without telling anyone.C. Write a thank-you note after a visit.D. Give a telephone call after a visit.COnce I thought love meant flowers, gifts and sweet kisses. So, I really doubted whether there was any love between my parents. Every day they were working hard to pay for my high school. They didn’t act in the romantic ways that I read in books and saw on TV, and they certainly didn’t send flowers to each other on Valentine’s Day (情人节).One day, my mother was sewing a quilt (被子). I asked her if there was any love betweenher and my dad. She stopped and raised her head in surprise. Then she went on with her work without saying anything. I was very worried because I thought I had hurt her feelings. But after a few minutes she said, “Look at this thread (线). Sometimes it appears, but most of the time it disappears in the quilt. If life is a quilt, then love is the thread. It can hardly be seen anywhere or at any time, but it’s really there, and makes the quilt long-lasting.” I listened carefully but I didn’t understand her until the next spring.My mother suddenly got seriously ill and had to stay in hospital for about a month. Every morning and evening after she returned from the hospital, my father helped her walk slowly along our country road. There were many beautiful flowers, green grass and trees, and the sun gently shone through the leaves. All of this made the most beautiful picture in the world. Reading their eyes, I knew they love each other deeply. From this experience, I realized that love is just a thread in the quilt of our lives. Love is inside, making life strong and warm.31. What does the underlined sentence in the third paragraph suggest?A. There is beautiful scenery where the writer lived.B. There is true love anywhere in the world.C. There is no love without beautiful flowers.D. There is true love between the writer’s parents.32. Why didn’t the writer’s mother answer his ques tion immediately?A. Because her husband didn’t love her.B. Because she was thinking of a better answer.C. Because she didn’t love her husband.D. Because the writer had hurt her feelings.33. What is the best title of this passage?A. Love Is EverywhereB. Love Is Always RomanticC. Love: Thread in QuiltD. Love Can Last ForeverDThis year some twenty-three hundred teenagers (young people aged from 13 to 19) from all over the world will spend about ten months in US homes. They will attend US schools, meet US teenagers, and form impressions (印象) of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and get a new understanding of the rest of the world.Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.Fred, an active young man, knew little German when he arrived, but after two months’ study, the language began to come to him. Schools were completely different from what he had expected ─ much harder. Students rose politely when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.Family life, too, was different. The father’s word was law, and all activities were around the family. Fred found the food too simple at first. Also, he missed having a car.“Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”At the same time, In America, Mike, a friendly German boy, was also forming his idea. “I suppose I should criticize (批评) American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do not hing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens (公民). There ought to be some middle ground between the two.34. The world exchange programme is mainly to __________.A. help teenagers in other countries know the real AmericaB. send s tudents in America to travel in GermanyC. let students learn something about other countriesD. have teenagers learn new languages35. Fred and Mike agreed that __________.A. American food tastes better than German foodB. German schools were harder than American schoolsC. Americans and Germans were both friendlyD. There were more cars on the streets in America36. In American schools __________.A. there is some middle ground between the two teaching buildingsB. there are a lot of after-school activitiesC. students usually take fourteen subjects in allD. students spend long hours studying37. After experiencing the America n school life, Mike thought __________.A. a better education should include something good from both America and GermanyB. German schools trained stud ents to be better citizensC. American schools were not as good as German schoolsD. the easy life in the American schools was more helpful to students第二卷(主观题共40分)四、词汇运用(本大题共8分,每小题1分)(A) 根据句意,写出括号内所给单词的适当形式。

下面是几则关于干旱的材料。

认真阅读分析材料,完成后面各题。

[材料一]农作物受旱面积[材料二][材料三]为了经济效益,我们仁化一些乡镇砍伐原生态林,大力种植杨树林和桉树林。

而这两种速生丰产林都被形象地称之为“抽水机”,涵水能力很差,大面积种植会导致地下水位下降。

此外,桉树还是“霸王树”,它生长了,其他物种会慢慢地退缩,最后造成桉树林都是地表光秃秃的,生态遭受颠覆性的破坏。

阅读以上材料,按要求完成下面二题。

⑴分析材料一和材料二,用简要的文字概述两则材料的主要信息。

(1分)答:⑵材料三说明了什么问题?(1分)答:⑶地球的水资源是有限的,仁化虽然不是缺水地区,但我们也应节约用水。

朝服衣冠,窥镜,谓其妻曰:“我孰与城北徐公美?”其妻曰:“君美甚,徐公何能及公也!”城北徐公,齐国之美丽者也。

忌不自信,而复问其妾曰:“吾孰与徐公美?”妾曰:“徐公何能及君也!”旦日,客从外来,与坐谈,问之客曰:“吾与徐公孰美?”客曰:“徐公不若君之美也!”明日,徐公来。

孰视之,自以为不如;窥镜而自视,又弗如远甚。

暮寝而思之曰:“吾妻之美我者,私我也;妾之美我者,畏我也;客之美我者,欲有求于我也。

”于是入朝见威王曰:“臣诚知不如徐公美,臣之妻私臣,臣之妾畏臣,臣之客欲有求于臣,皆以美于徐公。

今齐地方千里,百二十城,宫妇左右,莫不私王;朝廷之臣,莫不畏王;四境之内,莫不有求于王。

由此观之,王之蔽甚矣!”王曰:“善。

”乃下令:“群臣吏民,能面刺寡人之过者,受上赏;上书谏寡人者,受中赏;能谤讥于市朝,闻寡人之耳者,受下赏。

”令初下,群臣进谏,门庭若市。

数月之后,时时而间进。

期年之后,虽欲言,无可进者。

燕、赵、韩、魏闻之,皆朝于齐。

此所谓战胜于朝廷。

(3分)9.下列对本文有关内容的分析,不恰当的一项是(3分)()A.本文结构严谨。

三段分别写了比美、讽谏、纳谏,且有详有略,详略得当。

B.邹忌能够讽谏成功,除了他具有高超的讽谏艺术之外,也与齐威王善于纳谏分不开。

C.邹忌从妻、妾和客人说话的语气中明白了他们都故意用假话逢迎自己,以达到自己的目的,维护自己的利益。

D.邹忌用生活小事向齐威王委婉进谏,道理由浅入深,具有说服力。

(二)天才就是非凡的傻劲(10分)①关于天才,大小词典有相仿的释义:有卓绝聪明才智的人。

不知从何时开始,我渐渐质疑甚至厌烦起这种说法来。

②古今中外无数事例几乎都与词典上的释义相左:李时珍写《本草纲目》用了30年时间;托尔斯泰写《战争与和平》用了37年时间;歌德写《浮士德》用了60年时间;诺贝尔研制无烟炸药,屡败屡试,煎熬8年才出成果;陈景润为证明歌德巴赫猜想,拖着病体,顶着压力,于斗室之中、油灯之下埋头演算……真令人感叹!③。

然而,我读他们,非但没有读出他们的聪明才智,反而读出了他们的傻劲。

写一部书,有的几乎用了毕生精力,能说不傻?有的除了疯狂地埋头于自己的选择,简直不知世上还有其他可爱的事物,能说不傻?我们的世界丰富多彩,人生可享受的美妙也数不胜数。

许多聪明的人,有条件享受的,就去享受;没有条件享受的,也挖空心思创造条件享受。

哪像他们,糊涂到这般地步,不仅连常人最基本的享受都随便放弃了,而且千方百计自找苦头来吃。

④这些人物取得杰出的成就,究竟是凭傻劲还是靠聪明?⑤一生拥有1300多项发明专利的天才发明家爱迪生肯定地说,天才是1%的灵感加99%的汗水!现代人才学家也开始关注这一问题,他们研究得出:一个人事业上的成功,其专业知识或技术只起15%的作用,而其他方面要起85%的作用。

这其他方面都与“傻劲”有关:执著、正义感、责任感……这个结论同样把聪明才智放在第二位。

⑥如此看来,词典里的天才释义有些偏颇,建议对“天才”的释义重写,尽量强调有益于人类的成就,尽量突出“傻劲”的意义,淡化聪明才智的作用。

(作者柯登地)10.请在下列段序间用“‖”将本文分成三部分,联系上下文,为第③段开头写一个句子,使上下文连贯通畅。

(4分)(1)划层次:① ② ③④⑤ ⑥(2)补写开头:11.对本文理解分析有误的一项是()(3分)A.文章标题就是中心论点,观点鲜明。

B.文中“傻劲”是不会享受、糊里糊涂的意思。

作者认为“天才”需要这样的“傻劲”。

C.作者认为“天才”就是有非凡毅力、刻苦精神、卓越聪明才智且取得杰出成就的人。

D.作者列举了不少典型事例来证明自己的观点,具有较强的说服力。

12.请简要谈谈对作者观点的看法。

(3分)答:(三)(15分)烧炭工和绅士亚米契斯(1)诺比斯的父亲是当地有钱的绅士,因此诺比斯便趾高气扬,目中无人。

他父亲身材魁梧,蓄着浓密的黑胡子,表情十分严肃,几乎每天送儿子上学,接儿子放学。

昨天上午,诺比斯跟班里最小的一个孩子——烧炭工的儿子倍梯吵架。

诺比斯自知理亏,无法辩解,就冲着倍梯气急败坏地说:“你父亲是个乞丐!”倍梯委屈得要命,顿时面红耳赤,默不作声,热泪夺眶而出。

回到家里。

便把事情一五一十地告诉了父亲。

(2)午饭过后,全身黑糊糊、个子矮小的烧炭工领着孩子来到学校,向老师抱怨。

大家都不吱声,只是静悄悄地、全神贯注地听着。

跟往常一样,诺比斯的父亲正在门口给儿子脱外衣,他听到有人叫自己的名字,便走进教室。

问是怎么回事。

(3)“是这位先生在抱怨您儿子。

您儿子对他儿子说:‘你父亲是个乞丐!,”老师回答。

(4)诺比斯的父亲听后,皱皱眉头,羞愧得有点儿脸红,于是询问儿子:“你说那句话了吗?”诺比斯站在教室中间,当着倍梯的面,低着头不言不语。

父亲紧紧抓着儿子的胳臂,把他拉到倍梯的面前说:“快道声对不起。

”(5)烧炭工以和事老的口吻连声说:“算了吧,算了吧。

”(6)可绅士不理睬他,依然谆谆劝导儿子说:“照我的话这样说:‘我说了愚昧无知的话,侮辱了你的父亲,请你原谅。

如果我的父亲能紧握你父亲的手.那将是非常荣幸的!(7)烧炭工做了个果断的手势,好像在说:“我不愿意。

”绅士不听他的话,逼儿子照他说的办。
