They are generallycalled the British Isles. Of all these isles, thelargest one is called Great Britain. Forconvenience, it is often shortened to Britain. Stillto the west of Great Britain is the second largestisland known as Ireland. The United Kingdom ofGreat Britain and Northern Ireland(UK) is madeup of Great Britain, Northern Ireland, and a number of smaller islands around them. The total area of the country is some 240,000 square kilometers with a population of about 57 million.Great Britain runs nearly 1,000 kilometers from south to north and extends, at the widest part, about 500 kilometers from west to east. Its area is some 230,000 square kilometers. Great Britain is traditionally divided into three parts, or countries:England in the south, Scotland in the north, and Wales in the southwest. There are discernible(可辨别的) differences between them even now.England is the largest and most developed of all the three. Its area, about 130,000 square kilometers, takes up nearly 60% of the whole island. Its population is more than 46 million which makes up 85% of the country’s whole population. The importance of England is so great in Britain that some foreigners just say“England” when they mean Britain. The same is true of the custom of speaking of the British people as the English who are the majority in the United Kingdom.Scotland is the second largest both in area and population. It has an area of about 78,760 square kilometers, less than 30% of the whole island, with a population of 5 million, less than one-tenth of the whole population.Wales is the smallest of the three both in area and population. In area, 20,700 square kilometers,makes up less than 9% while its population, 2.7 million, does not exceed(超过)5% of the whole.1.The British Isles is made up of ________.A.the European Continent and Great BritainB.the UK. and the Republic of IrelandC.England, Scotland and WalesD.several thousands of islands to the west and off the European Continent2.Which of the following figures shows the correct position of Great Britain?3.We can infer that Great Britain has a population of about ________ million.A.54B. 46C. 60D. 57BYou probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?Jane Addams(1860-1935)Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community (社区) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.Rachel Carson (1907-1964)If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.Sandra Day O'Connor (1930-present)When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, shecould not find work at a law firm because she was a woman. She became an Arizona state senator(参议员) and, in 1981, the first woman to join the U.S. Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.Rosa Parks (1913-2005)On December 1,1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott(抵制). It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was, was tired of giving in,” s aid Parks.4. What is Jane Addams noted for in history?A.

Services such as hospital and transport are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.But in the big cities of Europe like London or Paris, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt of the city, and they are tired of the crowded streets, crowded trains and buses. They don't want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.So they move out of the cities. Some don't go very far, just to the towns near the cities. Otherpeople move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don't make so much money and there isn't much work to do. People in the countryside are very different and aren't always very friendly.As a result, quite a lot of people who have moved to the countryside move back to the city. “It's wonderful to see crowds in the streets and cinema lights,” they say.8. Which is NOT the reason for people moving to the cities in China?A. The countryside is much poorer than the city.B. People in the countryside don't have much work to do there.C. People in the countryside have nothing to eat.D. Services in cities are usually much better than those in the countryside.9. After moving to the countryside, some people in Europe feel unhappy because ________.A. they can't make much moneyB. there isn't much work for them to do in the countrysideC. some people in the countryside aren't always very friendly to themD. A, B and C10. The best title of this passage may be________.A. A happy life!B. Moving out or moving back?C. Living in the city!D. Living in the countryside!11. The underlined sentence in the last paragraph shows __________A. they miss their friends in the countrysideB. they are happy to move back to the cityC. they still want to move to the countrysideD. they are tired of the noise and the crowded streets in the cityDScotland has long been characterized as a land of romance. It contains ruins of many ancient castles, and there is an attractive beauty in its mountains, long deep valleys, and ribbon lakes. Each year those things attract a great number of tourists.Numerous islands line the coast. In the north are two large groups, the Orkney Islands and the Shetland Islands. Close to the west coast are the Inner and Outer Hebrides groups, and the islands of Arran and Bute.The land may be divided into three regions: the Highlands in the north, the Central Lowlands and the Southern Uplands.The Highlands are wild and picturesque(如画的). A long valley called Glenmore crosses the Highlands from southwest to northeast.In the south of the Highlands are the Grampian Mountains, highest in the British Isles. Ben Nevis, the highest peak, rises to 1,243 meters. Ben Lomond rises from the shore of Loch Lomond, Scotland's largest freshwater lake.The Central Lowlands run from southwest to northeast and the greatest length is nearly 145 kilometers. The soil here is fertile, and there are four coalfields underlying the area. In the east is Edinburgh, Scotland's historic capital city, and in the west is Glasgow. Almost 90 percent of Scotland's population live in the Lowlands.In the Southern Uplands, the hills are generally less than 600 meters high. Their rounded or flat tops are often capped with dark peat(泥炭). Along the slopes are plants like grass and heather(石南花).12.All the following things attract tourists to Scotland EXCEPT ______.A.ruins of ancient castlesB. mountains and valleysC. animals and plantsD. ribbon lakes13.From the passage we know that ________.A.the land consists of four partsB.the Highlands have rich soilC.

I have been a member for four years now and I’ve taken p art in a lot of interesting projects. These include fun activities such as holiday camps and discos. We have organized sports competitions and we even made a video.But it isn’t all just enjoyment, we have also started doing social work to help people in our neighbourhood. We have organized activities for small children during the holidays. We have also formed a social support group to help young people stop smoking.We are particularly proud of the most recent group we have created. It organizes regular v isits to the local old people’s home. This idea came from a school visit to an old people’ home. My class spent an afternoon at a home and everyone found the visit very rewarding.The old people at the home were very excited by our visit. They were very talkative(健谈的) and they told us their personal stories. During our visit ,the home was filled with the sound of laughter. We sang songs and played games with the old people and had tea together. But we realized that life wasn’t always easy. Some of them were in poor health and were very unhappy. They couldn’t go outside and the visits bychildren brought some sunshine into their lives.Many young people like me do not live with our grandparents and we have very littlecontact with elderly people. As a result, many young people don’t know what theyare like and we have a lot of wrong ideas about them. We have little or no idea ofthe kind of lives they lead in their homes. After this visit, my friends and I decidedwe should do something to help improve the quality of their lives.Since the creation of our visiting group, over twenty volunteers have joined us.Up to now, we have organized three group evenings and a concert. But it is theindividual(单独的) visits which are the most important. Club members regularly visitold people and everyone finds the experience rich and rewarding.24. The writer ____________.A. works at an old people’s homeB.lives with her grandparents.C. lives in an old people’s home.D.regularly visits old people.25. The Community Youth Club_______________.A. only organizes leisure activities for young peopleB. has made a video about life in an old people’s homeC. has arranged a school visit to the local old people’s homeD. mainly does social work.26. The writer thinks that many children today __________.A. are not interested in how old people liveB. do not want to get to know old peopleC. have very little contact with old peopleD. live with their grandparents27. As for Community Youth Club’s future, The author’s attitude to it is____________.A. positiveB. negativeC. neutralD. indifferentCIn recent years many countries have been faced with the problem of how to make their workers more productive. Some experts claim the answer is to make jobs more varied. But do more varied jobs lead to greater productivity? There is evidence to suggest that while variety certainly makes the worker's life more enjoyable, it doesn't actually make him work harder. As far as increasing productivity is concerned, then, variety is not an important factor.Other experts feel that giving the worker freedom to do his job in his own way is important. The problem is that this kind of freedom cannot easily be given in the modern factory with its complicated(复杂的) machinery. Thus while freedom of choice may be important, there is usually very little that can be done to create it.Another important consideration is how much each worker contributes to the product he is making. In most factories the worker sees only one small part of the product. Some car factories are now experimenting with having many small production lines so that each worker contributes more to the production of the cars on his line. It would seem that not only is degree of worker contribution an important factor, but it is also one we can do something about.To what degree does more money lead to great productivity? The workers themselves certainly think this is important. But perhaps they want more money only because the work they do is so boring. Money just lets them enjoy their spare time more. A similar argument may explain demands for shorter working hours. Perhaps if we succeed in making their jobs more interesting, they will neither want more money, nor will shorter working hours be so important to them.28. According to the author, what advantage do varied jobs bring?A. They increase productivity enormously.B. They reduce boredom among workers.C. They bring out the best in workers.D. They relieve workers' difficulties.29. What can we clearly see from the passage?A. It’s practical to allow more freedom in a modern factory.B. It's necessary to have a large number of workers.C. It's important to raise workers’ sense of contribution.D. It’s difficult to have more production lines.30. The passage seems to suggest that ________.A. more money leads to demands for shorter working hoursB. more money does not automatically create higher productivityC. workers like more money better than more interesting jobsD. workers expect to have both more money and more interesting jobs31. What does the passage mainly discuss?A. How to enrich workers'1ife.B. How to make workers more productive.C. How to shorten working hours.D. How to decrease dullness in a factory.DIf you do not use your arms or your legs for some time, they will become weak, and when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents may be blamed, and few of us know that it is just his own fault (过错). Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and when they have to remember things, they cannot write them down in a small notebook. As a result, they have to remember days, names, songs and stories, so their memory is being exercised the whole time.So if you want to have a good memory, learn from the people: practice remembering things in a way as other people do.32.Someone can’t have a good memory if ________.A.he can’t read or writeB.his parents haven’t a good memoryC.he doesn’t use his arms or legs for some timeD.he doesn’t make good use of his memory33.If you do not use your arms or legs for some time, ________.A.they will become thinB.they will become weakC.they begin to ache all overD.you can’t use them any more34.Few people know that if someone has a poor memory it is ________.A.his own fault B.his parents" faultC.his teachers" fault D.his friends" fault35 Give the best title for this passage. ____.A. Don't Stop Using your Arms or LegsB. Learn from the PeopleC. How to Have a Good MemoryD. Strong Arms and Good Memories第二节 (共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
