at school there had been an unhealthy competition between George and Richard.“I’ll be the first millionaire in Coleford!”Richard used to boast.“And you’ll be sorry you knew me,”George would reply“because I’ll be the best lawyer in the town!”George never did become a lawyer and Richard never made any money.Instead both men opened bookshops on opposite sides of Coleford High Street.It was hard to make money from books,which made the competition between them worse.Then Richard married a mysterious girl.The couple spent their honeymoon on the coast—but Richard nevercame back.The police found his wallet on a deserted beach but the body was never found.He must have drowned.Now with only one bookshop in town,business was better for George.But sometimes he sat in his narrow, old kitchen and gazed out of the dirty window,thinking about his formal rival(竞争对手).Perhaps he missed him?George was very interested in old dictionaries.He’d recently found a collector in Australia who was selling a rare first edition.When the parcel arrived,the book was in perfect condition and George was delighted.But while he was having lunch,George glanced at the photo in the newspaper that the book had been wrapped in.He was astonished—the smiling face was older than he remembered but unmistakable!Trembling,George started reading.“Bookends have bought ten bookstores from their rivals Dylans.The company,owned by multi-millionaire Richard Pike,is now the largest bookseller in Australia.”60.George and Richard were______at school.A.roommatesB.good friendspetitorsD.booksellers61.How did George

imagine how surprised people were when live fish rained down on them from a darkgray cloud.It happens that there are similar cases in England and Honduras.How do clouds make fishy?The simple answer is that they don’t.There is a particularweather phenomenon(现象)called a waterspout.A waterspout is just like a tornado(龙卷风),only it forms above oceans,lakes,or rivers.Like a tornado,a waterspout moves in a circle at highspeeds.When it moves above the water,it tends to carry the fish with it,as well as frogs orother small plants or animals.Scientists couldn’t work it out at first.To make matters stranger still,the fish in Honduras were very much alive when they rained down to the ground,but they were all blind.In England and Australia,it rained fish and snakes,and none were blind.It was difficult to puzzle out,but the blind fish gave them a place to start.Scientists knew that some fish that lived in deep,underground caves with no light sources often lost their eyesight.So when blind fish rained down on Honduras,scientists began toconnect some clues(线索,提示).Clearly,these particular fish were pulled from an underground water source by force.It has rained fish on every continent,and each time,people have tried in various ways toexplain this strange phenomenon.Historically,villagers thought the“fishes from the heavens”might be answers to prayers(祈祷)for food.Others suggested that floods overran river banks and oceans,leaving the fish on the city streets.No scientist had actually seen the rain as it occurred,only the fish left on the ground.But in1990,a National Geographic team happened to be inHonduras when the Rain of Fishes began.They recorded what was happening and made historyby finally proving that the fish really did fall from the sky.This huge breakthrough wasn’t just a spot of good luck.It changed thousands of yearsof myths(虚构的事;谬论)and legends into true stories and provided scientific explanations for how fish came to live in deep caves.It explained ancient cave paintings and cast(投射光线)new light on how species have spread over time.It turned out to be a lot more than just a little fishy weather.68.According to the passage,a waterspout________.A.can make animals blindB.is difficult to catch on filmC.can carry items(物品)with itD.is a dangerous sea creature69.The blind fish made the scientists start to think that________.A.raining fish was a warning of natural disastersB.animals changed to match their environmentsC.the weather system differed from place to placeD.the waterspout theory seemed more possible70.The first sentence in the last paragraph probably suggests that________.A.waterspouts came to be a center of scientific researchB.the scientists were fortunate to have made their discoveriesC.hard work went into determining the cause for the raining fishD.the scientists relied heavily on unusual events to drive their studies71.The author writes the passage to________.A.explain what caused the fishy weatherB.describe the magic phenomenonC.persuade people to protect the environmentD.encourage people to do scientific research(D)A study involving8,500teenagers from all social backgrounds found that most of them are ignorant(无知的)when it comes to money.The findings,the first in a series of reports from NatWesl that has started a five-year research project into teenagers and money,arc particularly worrying as this generation of young people is likely to be burdened with greater debts man any before.University tuition fees(学费)are currently capped at£3,000annually,but this will be reviewed next year and the Government is under enormous pressure to raise the ceiling.In the research,the teenagers were presented with terms(条款)of four different loans but76per cent failed to identify the cheapest.The young people also predicted that they would be earning on average£31.000by the age of25,although the average salary for those aged22to29is just£17,815.The teenagers expected to be in debt when they finished university or training,although half said that they assumed the debts would be less than £10.000.Average debts for graduates are£12,363.Stephen Moir,head of community investment at the Royal Bank of Scotland Group which owns NatWest, said."The more exposed young people are to financial issues,and the younger they become aware of them,the more likely they arc to become responsible,forward-planning adults who manage their finances confidently and effectively."Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs.They have just introduced new lessons in how to manage debts.Nikki Fairweathcr.aged15.from St Helens,said that she had benefited from lessons on personal finance,but admitted that she still had a lot to learn about money.72.Which of the following can be found from the five-year research project?A.Students understand personal finances differently.B.University tuition fees in England have been rising.C.Teenagers tend to overestimate their future earnings.D.The students'payback ability has become a major issue.73.The phrase"to raise the ceiling"in paragraph2probably means"______".A.to raise the student loansB.to improve the school facilitiesC.to increase the upper limit of the tuition(学费)D.to lift the school building roofs74.According to Stephen Moir,students_______.A.are too young to be exposed10financial issuesB.should learn to manage their finances wellC-should maintain a positive attitude when facing loansD.benefit a lot from lessons on personal finance75.What can we learn from the passage?A.Many British teenagers do not know money matters wellB.Teenagers in Britain are heavily burdened with debts.C.Financial planning is a required course at college.D.Young people should become responsible adults.Section C(8分)Directions:Read the following passage.Fill in each blank with a proper sentence given in the box.Each sentence can be used only once.Note that there are two more sentences than you need.A.Its goal is to have good,clean,fair food for all people.B.Today,there are great concerns about the way people grow and produce food.C.It should arrive on our plates in the cleanest and most environmentally responsible way.D.All people should be able to purchase healthy food.E.This event wasn’t the only thing that started the Slow Food Movement.F.Today the Slow Food Movement has already expanded out of Italy.The Slow Food Movement started in Rome,Italy in1986.When a new McDonalds wasopening near a beautiful historic place,some people stood outside the restaurant and shouted,“We do not want fast food.We want slow food!”(76)________One day Carlo Petrini went to a restaurant to eat a traditional meal.But thefood didn’t taste the same as he remembered.He learned that the peppers were shipped fromabroad because the prices were low.This deeply concerned Carlo.Carlo wanted people to care about where their foods came from and how their foods madetheir culture special.So he started a group to encourage this idea.It soon became the Slow Food Movement.(77)________First,what is good food?Good food is fresh.The vegetables are eaten close to the placewhere they are grown.The fish hasn’t been sitting for days before it is eaten.Good food isseasonable.It should be grown at the best time of the year for that food.Good food satisfies thesenses.It should look good,smell good and taste good.And finally,good food is cultural food.Each country has special foods that make it different.Second,food should be clean.(78)________Farmers use chemicals to kill insects andfeed plants.But the chemicals can also harm the natural environment around farms.Over time,they can cause health problems in people too.Clean food means food that does not harm ourbodies or the environment.And third,food should be fair.Food should not cost too much money.(79)________Thepeople who grow and make food should be paid fairly for their work.They should work in safe,Healthy conditions.第二卷I.Translation.(3+4+4+5=16分)80.作为学生,我们不应该无视校纪校规。

2. 以下说法正确的是()A. 某时刻物体的速度为零,其一定处于静止状态B. 物体速度变化量为负值时,它的加速度可能为正值C. 物体速度变化很快,其加速度一定很大D. 物体加速度的大小不断变小,则速度大小也不断变小【答案】C【解析】试题分析:静止状态是速度为零,加速度也为零的状态,故A错。

有加速度的定义式可知,加速度方向与速度变化量的方向一致,物体速度变化量为负值时,它的加速度一定为负值,故B错。

加速度是表征速度变化快慢的物理量,速度变化很快,其加速度一定很大,故C对。

物体加速度的大小表速度变化快慢,加速度变小,表速度变化变慢,而速度可以增大,也可以减小。

故D错。

故选C。

考点:加速度概念的考查。

3. 下列说法正确的是( )A. 重力单位牛顿是国际制基本单位B. 时间是国际单位制中一个基本物理量C. 物理量质量是矢量D. 长度的国际制基本单位是千米【答案】B【解析】A项:牛顿是国际单位制的导出单位,不是基本单位,选项A错误;B项:力学中的基本物理量为质量、长度、时间,故B正确;C项:质量只有大小,没有方向,所以质量为标量,故C错误;D项:长度的国际制基本单位为米,故D错误。

In theory, if humans were able to do this, they could travel to distant planets in (21) ________ matter of minutes.In Madeleine L'Engle's novel, A Wrinkle in Time, the idea goes one step further: instead of travelling at great speeds, she processes a theory (22) ________ allows humans to travel through a fifth dimension(维度). This means that you could get from Earth to another planet in a distant galaxy almost instantly.First (23) ________ (publish) in 1960, L' Engle's novel has captured the imaginations of young science-fiction fans all over the world for decades -- and now it (24) _______ (turn) into a film. The story follows 13-year-old Meg Murry, played by Storm Reid, who is seen by her classmates and teachers (25) ________ a troublesome pupil. She is the daughter of two world-famous physicists, but is saddened by the mysterious disappearance of her father. To help find her dad, three supernatural beings, Mrs. Who, Mrs. Whatist and Mrs. Which, transport Meg, her genius brother, Charles Wallace, and her classmate, Calvin, through the universe. (26) ________ (travel) through a wrinkling of time and space, also known as "tessering", they are soon transported to worlds that they never thought (27) ________ (exist).(28) ________ the film follows the story of the book, not everything could be fitted in. One detail that fans of the book may notice is (29) ________ Meg's twin brothers have been written out of the script.Oprah Winfrey, who plays Mrs. Which, says the film is like The Wizard of Oz for a new generation.

"I think of it as a film for generations (30) ________ (come)."Section BDirections: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.The meaning of silence varies among cultural group. Silence may be 31 , or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, uneasiness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every 32 with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person’s needs. Many nati ve Americans value silence and feel it is a basic part of 33 among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of theseculture is speaking and suddenly stops, what may be 34 is that the person wants the listener to consider what has been said before continuing. In these culture, silence is a call for 35 .Other cultures may use silence in other ways, particularly when dealing with 36 among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show 37 between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.Nurses and other care-givers need to be aware of the 38 meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient’s silence is not 39 too early or allowed to go on unnecessarily. A nurse who understands the healing 40 of silence can use this understanding to assist in the care of patients from their own and from other cultures.III.

The key point of the idea known as animal rights is a movement to extend moral consideration to all ___42___ beings. Nobody should have to demonstrate a specific level of intelligence or be judged beautiful to be given moral consideration. No being should have to be useful to humanity or capable of accepting “duties” in order t o be extended moral consideration. ___43___, what other animals need from us is being free from duties to us.Animal rights is about letting animals live on their own terms. It can be written into our laws, but is not an actual list or bill of rights as we have for human society. It begins with our promises not to act like ___44___ of others. Animal rights is about justice ─ treating animals fairly.Why is animal rights ___45 ___? It is because we humans often act as though we are the only beings on the planet.

All animals wish to experience life in its fullness. Unlike many animals who have to kill to survive, humans do not. Why should humans cause ___48___ to other beings when it’s not necessary?As we do, animals protect their children; they feel fear; they warn each other of dangers; they play. We might differ from other animals in some ways, but that doesn’t give us the right to ___49___ them down, take their lands, pollute their waters, or use them for our conveniences.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C, D. Choose the one that fits best according to the information given in the passage you have read.(A)I used to think ants knew what they were doing. The ones marching across my kitchen counter looked so confident; I just figured they had a plan, knew where they were going and what needed to be done. How elsecould ants organize highways, build elaborate nests, launch impressive attacks, and do all the other things ants do?Turns out I was wrong. Ants aren’t clever little engineers, architects, or soldiers after all --- at least not as individuals. When it comes to deciding what to do next, most ants don’t have a clue. “If you watch an ant try to accomplish something, you’ll be impressed by how awkward it is,” says Deborah M.Gordon, a biologist at Stanford University.“Ants aren’t smart,” Gordon says. “Ant colonies are.” A colony can solve problemsunthinkable for individual ants, such as finding the shortest path to the best food source,assigning workers to different tasks, or defending a territory from neighbors. Asindividuals, ants might be tiny dummies, but as colonies they respond quickly andeffectively to their environment. They do it with something called collective intelligence.Where this intelligence comes from raises an essential question in nature: How do the simple actions of individual ants add up to the complex behavior of a group? How do hundreds of honey-bees make a critical decision about their hive (蜂巢)if many of them disagree? The collective abilities of such animals --- one of which grasps the big picture, but each of which contributes to the group’s success --- seem miraculous even to the biologists who know them best. Yet during the past few decades, researchers have come up with fascinating insights.56.The author’s former false impression about ants is that he thought them to be _______.A. smartB. awkwardC. elaborateD. creative57.Which of the following is TRUE according to the passage?A. Ants will function as a single body once a decision is made by the commander.B. Ants are the only species which developed collective intelligence.C. The ant queen plays a role in managing ant workers besides laying eggs.D. An individua l ant can’t comprehend the whole process of a big movement.58.The paragraph following the passage will most probably deal with _______.A. where we can observe such fantastic behavior of antsB. which is the leading ant in charge of the actionC. how the collective intelligence worksD. what inspiration can be drawn from the collective abilities(B)In spring, chickens start laying again, bringing a welcome source of protein at winter's end. So it's no surprise that cultures around the world celebrate spring by honoring the egg.Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into a fancy art, like the heavily jewel-covered “eggs” that were favored by the Russians starting in the 19th century.One ancient form of egg art comes to us from Ukraine. For centuries, Ukrainians have been drawing complicated patterns on eggs. Contemporary artists have followed this tradition to create eggs that reflect the anxieties of our age: Life is precious, and delicate. Eggs are, too.“There’s something about their delicate nature that appeals to me,” says New Yorker cartoonist Roz Chast. Several years ago, she became interested in eggs and learned the traditional Ukrainian technique to draw her very modern character s. “I've broken eggs at every stage of the process一from the very beginning to the very, very end. ”But there’s an appeal in that vulnerability. “There’s part of this sickening horror of knowing you’re walking on the edge with this, that I kind of like, k nowing that it could all fall apart at any second.” Chast’s designs, such as a worried man alone in a tiny rowboat, reflect that delicateness.Traditional Ukrainian decorated eggs also reflect those fears. The elaborate patterns were believed to offer protection against evil.“There’s an ancient legend that as long as these eggs are made, evil will not prevail in the world,” says Joan Brander, a Canadian egg-painter who has been painting eggs for over 60 years, having learned the art from her Ukrainian relatives.The tradition, dating back to 300 B. C., was later incorporated into the Christian church. The old symbols, however, still endure. A decorated egg with a bird on it, given to a young married couple, is a wish for children. A decorated egg thrown into the field would be a wish for a good harvest.59. People in many cultures prize the egg because __________________.A. It can bring wealth and honor to them.B. It can easily be made into a work of art.C. It is their major source of protein in winter.D. It is a welcome sign of the coming of spring.60. What do we learn about the decorated “eggs” in Russia?A. They are cherished by the rich.B. They are favored as a form of art.C. They are shaped like jewel cases.D. They are heavily painted in red.61. Why have contemporary artists continued the egg art tradition?A. Eggs reflect the anxieties of people today.B. Eggs provide a unique surface to paint on.C. Eggs have an oval shape appealing to artists.D. Eggs serve as an enduring symbol of new life.62. Why does Chast enjoy the process of decorating eggs?A. Because she always gets great pleasure from designing something new.B. Because she is never sure what the final design will look like until the end.C. Because she can add multiple details to the design to communicate her idea.D. Because she never knows if the egg will break before the design is completed.Section CDirections:Read the passage carefully. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.A. In the upper parts of the atmosphere, it will burn up.B. There are also millions of smaller pieces of junk that we can’t see.C. Blowing up older satellites with a missile may create thousands of smaller pieces!D. One reason that it’s urgent is that countries are sending more and more objects into space.E. When two objects in space collide, the two objects break into many smaller pieces.F. Years of space exploration have left tons of “space junk” in orbit (轨道) around the planet.Many people know that trash is a big problem on planet Earth. What many people don’t know is that trash has become a problem in outer space too. (63) _________________________Statistically, there are more than 22,000 pieces of junk in space around the earth. And these are just the items that we can see from the surface of the earth by telescopes or radars. (64) ___________________Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to people, particularly astronauts. If the tiniest piece of junk crashed into a spacecraft, it could damage the vehicle. That’s because the faster an object moves, the greater the impact if the object collides with something else.To help minimize additional space junk, countries around the world have agreed to limit the time their space tools stay in orbit to 25 years. Each tool must be built to fall s afely into the earth’s atmosphere, or the mass of gases that surround the earth, after that.

天快夜了,别的雀子似乎都在休息了,只杜鹃叫个不息。

石头泥土为白日晒了一整天,草木为白日晒了一整天,到这时节皆放散一种热气。

空气中有泥土气味,有草木气味,且有甲虫类气味。

翠翠看着天上的红云,听着渡口飘乡生意人的杂乱声音,心中有些儿薄薄的凄凉.....。

但一个人若体念到这个当前一切时,也就照样的在这黄昏中会有点儿薄薄的凄凉。

于是,这日子成为痛苦的东西了。

翠翠觉得好象缺少了什么。

好象眼见到这个日子过去了,想在一件新的人事上攀住它,但不成。

好象生活太平凡了,忍受不住。

……③两人吃饭时,祖父为翠翠说到一些有趣味的故事。

因此提到了死去了的翠翠的母亲。

两人在豆油灯下把饭吃过后,老船夫因为工作疲倦,喝了半碗白酒,因此饭后兴致极好,又同翠翠到门外高崖上月光下去说故事。

说了些那个可怜母亲的乖巧处,同时且说到那可怜母亲性格强硬处,使翠翠听来神往倾心。

④翠翠抱膝坐在月光下,傍着祖父身边,问了许多关于那个可怜母亲的故事。

间或吁一口气,似乎心中压上了些分量沉重的东西.......,想挪移得远一点,才吁着这种气,可是却无从把那东西挪开。

⑤月光如银子,无处不可照及,山上篁竹在月光下皆成为黑色。

身边草丛中虫声繁密如落雨。

间或不知道从什么地方,忽然会有一只草莺“落落落落嘘!”啭着它的喉咙,不久之间,这小鸟儿又好象明白这是半夜,不应当那么吵闹,便仍然闭着那小小眼儿安睡了。

⑥祖父夜来兴致很好,为翠翠把故事说下去,就提到了本城人二十年前唱歌的风气,如何驰名于川黔边地。

翠翠的父亲,便是唱歌的第一手,能用各种比喻解释爱与憎的结子,这些事也说到了。

翠翠母亲如何爱唱歌,且如何同父亲在未认识以前在白日里对歌,一个在半山上竹篁里砍竹子,一个在溪面渡船上拉船,这些事也说到了。

⑦翠翠问:“后来怎么样?”⑧祖父说:“后来的事长得很,最重要的事情,就是这种歌唱出了你。

五、文言文阅读(21分)种树郭橐驼传(柳宗元)郭橐驼,不知始何名。

病瘘,隆然伏行,有类橐驼者,故乡人号之“驼”。

驼闻之,曰:“甚善。

名我固当。

”因舍其名,亦自谓橐驼云。

其乡曰丰乐乡,在长安西。

驼业种树,凡长安豪富人为观游及卖果者,皆争迎取养。

视驼所种树,或移徙,无不活,且硕茂,蚤实以蕃。

他植者虽窥伺效慕,莫能如也。

有问之,对曰:“橐驼非能使木寿且孳也,能顺木之天,以致其性焉尔。

凡植木之性,其本欲舒,其培欲平,其土欲故,其筑欲密。

既然已,勿动勿虑,去不复顾。

其莳也若子,其置也若弃,则其天者全而其性得矣。

故吾不害其长而已,非有能硕茂之也。

不抑耗其实而已,非有能蚤而蕃之也。

他植者则不然,根拳而土易,其培之也,若不过焉则不及。

苟有能反是者,则又爱之太恩,忧之太勤。

旦视而暮抚,已去而复顾,甚者爪其肤以验其生枯,摇其本以观其疏密,而木之性日以离矣。

虽曰爱之,其实害之;虽曰忧之,其实仇之,故不我若也。

吾又何能为哉!”问者曰:“以子之道,移之官理,可乎?”驼曰:“我知种树而已,官理,非吾业也。

然吾居乡,见长人者,好烦其令,若甚怜焉,而卒以祸。

旦暮吏来而呼曰:‘官命促尔耕,勖尔植,督尔获,早缫而绪,早织而缕,字而幼孩,遂而鸡豚。

’鸣鼓而聚之,击木而召之。

吾小人辍飧饔以劳吏,且不得暇,又何以蕃吾生安吾性耶?故病且怠。

若是,则与吾业者其亦有类乎?”问者曰:“嘻,不亦善夫!吾问养树,得养人术。

”传其事以为官戒也。
