I play the guitar, and can say that I’m really good at it. I also like playing c hess, but I don’t play it well. If you’re good at it, maybe you can teach me. I’m going to college this September. All I really want to do during the summer holiday is travel, teach, and learn languages (this is my hobby), see things, and build great frien dships. I’d like people aged 17-20 to get in touch with me, both girls and boys. It’s better if you’re from Beijing or Tokyo.I’ve made 15 friends over the Internet. If you’d like to be one of them, send me an email at blink001@. My MSN is blink001@. I’d love to be your friend!21. Where is Blink now?A. In Dodge City.B. In Pratt.C. In Beijing.D. In Tokyo.22. What is Blink NOT good at?A. Playing the guitar.B. Playing ball games.C. Playing chess.D. Learning languages.23. What is Blink’s purpose of writing this passage?A. To make friends.B. To go on a trip.C. To learn foreign languages.D. To introduce his hobbies.( B )When you visit America, you will s ee the word “Motel ”on signs and notice boards. It is made up of “motor” and “hotel” and it is really a hotel for people who arrive by car (however, you don’t need a car to stay at one). You have to pay when you arrive for your room, which usually has a bath. Meals are not provided, but there will certainly be a cafeteria ( 自助餐馆 ). Americans eat a lot of salads and sandwiches. Along the main roads there are a lot of motels. Each tries to offer more than next. Some provide television in every bedroom; others have swimming pools; and so on. Motels are especially useful when you are in the country, far from a town or city. You will also find them in the big National Parks.In these great National Parks, you may meet guests you don’t expect to see. An American friend told me a little story. In the middle of a moonless night she heard strange noises outside her motel window in the Yellowstone National Park in Wyoming. Thinking it might be a thief, she jumped out of bed, opened the door and crept towards a dark shadow. As she got close, she saw the thief. She was dreadfully frightened: it wasn’t a human thief — it was a big black bear. The bear was turning over some empty tins with its paw, looking for tasty bits of food. My friend decided to leave that particular thief alone!There are also, of course, places called “rooming houses”, where they receive lodgers ( 房客 ). You will see such signs as Tourists or Rooms Rent, and you could try one of these. A word of warning — looking for a room in New York during the tourist season is like looking for gold on the moon!24. Which of the following is TRUE about motels?A. The word “motel” is formed by two words.B. They are free for people who arrive by car.C. If you want to stay at a motel, you must have a car.D. You can only find motels in the big National Parks.25. Which of the following is NOT provided by motels?A. Meals.B. Swimming pools.C. TV.D. Baths.26. From the last paragraph, we can learn that in New York during the touristseason ______.A. tourists can find gold thereB. it is difficult to find a room thereC. tourists can have a sweet dream thereD. there is a warning for touriststo New York( C )Deserts are found where there is little rainfall or where rain for a wholeyear falls in only a few weeks' time. Ten inches of rain may be enough for manyplants to survive ( 存活 ) if the rain is spread throughout the year, If it falls,within one or two months and the rest of the year is dry, those plants may dieand a desert may form.Sand begins as tiny pieces of rock that get smaller and smaller as windand weather wear them down. Sand dunes ( 沙丘 ) are formed as winds move thesand across the desert. Bit by bit, the dunes grow over the years, always movingwith the winds and changing the shape. Most of them are only a few feet tall,but they can grow to be several hundred feet high.There is, however, much more to a desert than sand. In the deserts ofthe southwestern United States, cliffs ( 悬崖 ) and deep valleys were formedfrom thick mud that once lay beneath a sea more than millions of years ago. Overthe centuries, the water dried up. Wind, sand , rain, heat and cold all woreaway at the remaining rocks. The faces of the desert mountains are always changing—very, very slowly —as these forces of nature continue to work on the rock.Most deserts have a surprising variety of life. There are plants,animals and insects that have adapted to life in the desert. During the heatof the day, a visitor may see very few signs of living things, but as the airbegins to cool in the evening, the desert comes to life. As the sun begins torise again in the sky, the desert once again becomes quiet and lonely.27. Many plants may survive in deserts when___________.A. it is dry all the year roundB. the rain falls only ina few weeksC. there is little rain in a yearD. the rain is spread out in a year28. Sand dunes are formed when___________.A. sand piles up graduallyB. there isplenty of rain in a yearC. the sea has dried up over the yearsD. pieces of rock getsmaller29. The underlined sentence in the third paragraph probably means that in a desertthere is_________.A. too much sandB. more sandthan beforeC. something else besides sandD. nothing exceptsand30 It can be learned from the text that in a desert____________.A. life exists in rough conditionsB. there is no rainfallthroughout the yearC. all sand dunes are a few feet highD. rocks are worn away only bywind and heat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，并在答题卡将该项涂黑。

AThe Colonel（上校）asked Ashenden a good many questions and then suggested that he had particular qualifications （资格证）for the Secret Service ( 特勤处) . Ashenden knew several European languages and the fact that he was a writer provided excellent cover: on the pretext （以…为借口） that he was writing a book he could, without attracting attention, visit any neutral ( 中立) country.It was while they were discussing this point that the Colonel said, "You know you might get material that would be very useful to you in your work. I'll tell you an incident that occurred only recently. Very dramatic ( 戏剧性) . A foreign government minister went down to a Mediterranean resort ( 地中海度假胜地) to recover from a cold and he had some very important documents ( 文件) with him that he kept in a dispatch case（公文箱）. A day or two after he arrived, he picked up a beautiful blonde ( 金发女郎) at some restaurant or other, and he got very friendly with her. He took her back to his hotel, and when he came to himself in the morning, the lady and the dispatch-case had disappeared. They had one or two drinks up in his room and his theory is that when his back was turned the woman slipped a drug in his glass."Do you mean to say that happened the other day?" said Ashenden."The week before last.""Impossible," cried Ashenden. "Why! We've been putting that incident on the stage for sixty years, we've written it in a thousand novels. Do you mean to say that life has only just caught up with us?""Well, I can guarantee ( 保证) the truth of the story." said the Colonel, "And believe me, the government has been put to no end of trouble by the loss of the documents.""Well sir, if you can't do better than that in the Secret Service," sighed Ashenden, " I'm afraid that as a source of inspiration ( 灵感) to the writer of fiction, it's washout （失败）."21． How did the Colonel suggest that Ashenden's being a writer would relate to his work as a spy?A. It would make traveling abroad more possible.B. It would make it easier for him to meet people.C. It would enable him to avoid arousing suspicion.D. It would enable him to use the languages he knew.22．The reason for the Minister's trip was ________ . A. to fetch some documents B. to get over an illnessC. to meet a spyD. to deliver some papers23．According to the Colonel the incident happened _______ .A. a few days beforeB. a few weeks beforeC. two weeks beforeD. sixty years before24．Ashenden cried 'Impossible' after hearing the Colonel's story because he thought ______ .A. it was so stupidB. it was too close to fictionC. it was too embarrassingD. it was too recentBTo prevent the deserts coming near, China has planted billions of trees---to replace destroyed f orests and as barriers against the sand. This isn’t a cure, though, say experts, as thirsty trees can make the problem worse by taking in groundwater.“Planting tress is one way, but it isn’t that simple. It doesn’t solve the basic issue of water resource s,” says Wu Bo, a professor. “We need to calculate how much water the trees will absorb, or else it could have a negative effect ( 负面影响).”Villagers in Zhengxin have taken on this challenge, with limited success. When the irrigation channels began to run dry, Lu Xianglin switched from wheat to cotton on his land. He also planted trees to protect his fields from sandstorms. He says he still gets good yields （产量） using flood irrigation and earns a good income for his family.Other farmers haven’t stuck it out（坚持到底）: about one in three have left Zhengxin in the past 10 years after their wheat crops died. Young people who can find jobs in the towns rarely return.Last week, Mr Lu joined the other men in his village on a government-arranged trip to see the land that has been set aside for their relocation ( 重新安置) , nearly 40 miles to the south. The next day, he was back, shaking his head at the plan. The idea of uprooting his family troubles him, as does the idea of giving up the land that fed his forefathers ( 祖先). He prefers to stay and keep up the fight.“With enough water, this problem can be solved,” Lu says. “We can plant trees and grass, and they will grow bigger. That will stop the desert.”Experts say that farmers could switch to drip irrigation （滴灌）to lessen their water intake for growing crops. Elsewhere in the region, farmers have built brick greenhouses as part of a plan to grow vegetables using less water. Roadside signs urge farmers to “Save Water, Protect the Environment”.25. The negative effect of planting trees in deserts is that __________.A. it can make groundwater become lessB. it can prevent the sand moving freelyC. it can stop crops growing wellD. it can get the soil to become poor26. Why did Mr. Lu NOT accept the idea of relocation?A. Because the plan of relocation will cost him much money.B. Because his family had trouble moving away.C. Because he was reluctant to give up his land.D. Because he would rather stay than fight against the deserts.27. What can we infer from the passage?A. The deserts drive more and more people to leave their homes for their lives.B. People have no means to fight against the land becoming desert.C. Water is the biggest barrier for people to stop the desert.D. Planting trees cannot solve the problem of desertification of farmland.28. What advice is given by experts to save water?A. To plant more trees.B. To build greenhouses.C. To change crops.D. To use drip irrigation.CHere are four pieces of news from China Daily:SHANGHAI---The Huachen Group, which has put 83 million yuan in the development of the commerce market since its official registration (正式注册) late last year, recently held a meeting in Shanghai to show the use of its newly opened tourism business payment network. The network aims to serve tourists from all over the world, but especially from Europe and the United States where credit cards are popularly used. After opening the website, netizens ( 网民) can get information about hotels and tourism services on tourism page. Hotels and services can be reserved ( 预定) and payment made through credit cards. The network opened in February in Beijing.SYDNEY---The Sydney Olympic flame will travel underwater on Australia’s Great Barrier Reef during the torch relay ( 火炬接力) following a successful test.Scuba diver Wendy Craig, a marine biologist ( 海洋生物学家) , will carry the torch on three-to-four-minute underwater journey at Agincourt Reef on June 27, creating Olympic history, organizers said yesterday.Burning at 2,000 degrees, the torch is expected to remain alight three meters underwater because of a special kind of technology whic h creates a “fierce flame”--- too powerful to be drowned out by water. Charles Tegner, managing director of torch creator, said the flame would burn like a flame from oxygen-producing chemicals.BEIJING---The election of a new leader in Taiwan cannot change the fact that Taiwan is part of China. “Taiwan Independence( 台独) ” in whatever form will never be allowed, according to a statesman of China’s central government.“We should listen to what the new leader in Taiwan says and watch what he does. We will observe where he will lead Cross-Straits relations ( 海峡两岸). We are willing to exchange views on Cross-Straits relations and peaceful reunification (统一) with all parties, organizations and people in Taiwan who favor the one-China principle ( 一个中国原则),” says the statesman, from Taiwan Affairs Office of the CPC Central Committee.HAIKOU---Customs officers in Haikou, capital of South China’s Hainan Province, recently stopped a boat loaded with 781 cases of foreign-brand cigarettes being smuggling ( 走私) into China. The cigarettes are estimated ( 估计) to be worth more than 1.8 million yuan, said a customs officer. They discovered the smuggling boat as they were going around thenorthern sea area of Yangpu Port.The smuggled cigarettes cases, packed into two containers, were disguised to avoid being examined. The boat was registered in the coastal city Xiamen in East China’s Fujian Province. All eight suspects ( 嫌犯) aboard the boat were kept by the police in Haikou.29. Why does the network aim to serve tourists especially from Europe and the USA?A. Because they are from developed countries.B. Because the payments of hotels and services are usually made through credit cardsin these places.C. Because people in these countries travel much more than those in other countries.D. Because they have more computers than others.30. Which is the best title for the third piece of news?A. Ready to FightB. No Good EndC. Wait and SeeD. Peace Comes First第二节：七选五（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。

A．People can hail the driverless robotaxi free of charge.B．The autonomous vehicle is in service around the nation.C．The robotaxi service can cover a wide range of locations.D．It is provided for the citizens in Guangzhou at any time.7．What remains to be done to achieve fully autonomous driving?A．Expanding the robotaxi services to more cities.B．Carrying out more tests on the autonomous vehicles.C．Developing the self-driving technology to a large extent.D．Calling for the companies to improve self-driving services.A tiny Alaska village has experienced a boom in tourism in recent years as polar bears spend more time on land than on Arctic sea ice.More than2,000people visited the northern Alaska village of Kaktovik in2018to see polar bears in the wild.The far north community lies in an area where increasingly higher temperature has sped up the movement of sea ice,the primary habitat(栖息地)of polar bears. As ice has gradually moved to deep water beyond the continental shelf,more bears are remaining on land to look for food.Polar bears have always been a common sight on sea ice near Kaktovik,but villagersstarted noticing a change in the mid-1990s.More bears seemed to stay on land,and researchers began taking note of more female bears making homes in the snow on land instead of on the ice to raise their babies.U.S.Fish and Wildlife Service biologists began hearing reports of the increasing number of polar bears in the area in the early2000s.As more attention was given to the plight(困境)of polar bears about a decade ago,more tourists started heading to Kaktovik.The village had fewer than50visitors annually before2011,said Jennifer Reed,of the Arctic National Wildlife Refuge.“Today we’re talking about hundreds and hundreds of visitors,many from around the world each year,”Reed said.Most tourists visit in the fall, when bears are forced toward land because sea ice is farthest away from the shore.Bruce Inglangasak,a local hunter who sometimes offers wildlife-viewing tours,said he's been offering polar bear tours since2004.Most of his clients(客户)are from China and Europe,as well as from the lower48U.S.states.Many tourists stay several days in the village,which has two small hotels.The villagers have benefited a lot from that.In turn,they provide more effective protection for polar bears with financial support from tourism development. 8．What causes more polar bears to stay on land in Kaktovik?A．Food shortage.B．Climate change.C．Habitats’movement to shore.D．Their preference for land.9．How did common people feel about more sight of bears on land?A．Excited.B．Puzzled.C．Concerned.D．Shocked. 10．What can be inferred from the last paragraph?A．Hotels in Kaktovik are in demand in autumn.B．Kaktovik has about50visitors annually. C．Inglangasak makes a living as a tour guide.D．Tourism affects the balance of nature. 11．Which saying can describe the text?A．The fittest can survive.B．After a storm comes a calm. C．One man’s fault is another man’s lesson.D．Every coin has two sides.Do you know how it is when you see someone yawn and you start yawning too?Or how hard it is to be among people laughing and not laugh yourself?Well,apparently it’s because we have mirror neurons(神经元)in our brains.Put simply,the existence of mirror neurons suggests that every time we see someone else do something,our brains imitate it,whether or not we actually perform the same action.ThisD．determine our knowledge and language abilities.三、完形填空I’ve been farming sheep on a hillside for54years.I use a small tractor to get about.My34．A．ability B．dream C．idea D．luck 35．A．lesson B．meal C．job D．test四、用单词的适当形式完成短文五、告知信/通知46．新年即将来临，学生会将于星期五晚上8：00—10：00在学校五楼报告厅举办一场英语晚会，现请你以学生会的名义发一份英语书面通知，欢迎全校师生参加，通知包含以下要点：1.晚会主题：“迎新春，享受英语”；2.节目内容；3.参会要求。
