It is said that the car has made the United States a nation on wheels. And it helped to make the United States what it is today.There are three main reasons why the car became so popular in the Unites States. First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation.The second reason is that the United States never really developed an efficient and cheap form of public transportation. Long-distance trains have never been as common in the United States as they are in other parts of the world. Today there is a good system of air service by plane. But air travel costs too much money so that it cannot be used frequently.The third reason is the most important one. The American spirit of independence is what had really made cars popular. Americans don’t like to wait for a bus, or a train or even a plane. They don’t like to have to follow an exact timetable. Ther efore the freedom a car gives them is what Americans want most.The decrease of oil supplies has caused a big problem for Americans. But the fear will not be bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much oil.51. That the United States is called a nation on the wheel is because .A. cars are very popular in AmericaB. there are many wheels in AmericaC. there are many planes in AmericaD. there are many trains in America52. The most important reason why cars are so popular in the US is .A. Americans like to visit different placesB. Americans like to go about freelyC. the American spirit of independenceD. other types of transportation are not so efficient53. According to the sentence “ And it helped to make the United States what it is today”(Line 2,Para1), we can conclude that .A. the car has made the United States a very rich countryB. the transportation has been developed rapidlyC. the car has become America’s most modern form of transportationD. the car has made it possible for Americans to enjoy their modern life54. All of the following statements are true except .A. the American people are quite mobileB. air service plays an equally important part as the car doesC. people have been trying to find the solution to the short supplies of oilD. Americans’ independent spirit plays a role in the popularity of cars55. The word “efficient” in the third par agraph probably means .A. inexpensiveB. economicalC. convenientD.speedyCOn my first day of high school, I asked an eleventh-grader where my class was. And he told me it was "on the fourth floor, next to the pool." I found out five minutes later that we didn't even have a fourth floor and there was no pool either! Besides that, I didn't have any trouble with the older kid.I think the biggest difference between middle and high school is the homework load (工作量) and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music and other activities at school makes it easier to get to know people in every grade.The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I've prepared for the night before, gotten an A, but not remember anything later. I've changed that this year, and I enjoy school so much more. Don't take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!While drinking and smoking might be present in some middle schools, they are also around in high school. I have a lot of friends who promised they would never drink or smoke, but are now partying every weekend. If you have "fun" and spend your nights wasted instead of studying, you will regret it when you are applying for (申请) college. The "friends" who say you are a loser for not partying are really not your friends at all. It's hard to see your closest friends grow apart and go in different directions, but don't follow their footsteps. Follow your own path in life and make your own decisions.56What happened to the writer on his first day of high school?A. He had a fight with an eleventh-grader.B. He was fooled by a schoolboy.C. He was five minutes late for class.D. He fell into a pool on the fourth floor.57According to paragraph 2, the writer thinks that in high school _____.A. It needs hard work to finish homeworkB. There are very few activitiesC. It's hard to meet new people thereD. There is always much free time58The writer advises high school students to _____.A. give up sportsB. choose useful classesC. try their best to get good gradesD. get ready for test the night before59.The passage is probably written for ______.A. high school studentsB. high school teachersC. college studentsD. sports players60.The last paragraph mainly tells us ______.A. about the trouble caused by drinking and smokingB. about the importance of making friendsC. not to go to any party in high schoolD. not to lose ourselves in high schoolDSteven woke on Christmas morning to find a new sled (雪橇). "Oh, wow!" he shouted. This was the best Christmas present! Steven was still excited as the rest of his family opened their gifts. Secretly, he hoped he could get outside quickly to try out his new sled.Finally, Steven asked, "Dad, is it okay if I try out my sled?" Dad agreed. Soon, Steven was sledding down Twin Hills in the neighbourhood park. He felt the wind against his face as he flew down.Later that day, Steven carefully leaned (靠) the sled up against the outside of his house under his bedroom window.The next day, Steven ran outside as soon as he could. "Oh, no!" Steven shouted. His sled was missing! He ran as fast as he could to the park. There at Twin Hills he found it! Steven's neighbour, Kevin, was on Steven's new sled! "Kevin! That's my sled! You stole my new sled!" But Kevin just laughed and headed up the hill for another run down.Steven ran home, crying all the way. He found his dad in the garage (车库) and told him what had happened. Steven's dad said, "Calm down, Son. There may be another reason for the missing of your sled."Steven couldn't believe his dad was siding with Kevin. "But, Dad. Kevin's at Twin Hills using my sled right now! We need to go to get it!"Dad said patiently, "First of all, you need to make sure your sled is actually stolen. Look over there." Steven was surprised at what he saw. His sled leaned against the wall of the garage next to his bicycle. Dad put his arm around Steven and said, "I put your sled away last night when I saw you had left it outside." Steven hung his head. He felt bad about the way he had spoken to his neighbour. "I should say sorry to Kevin," he said. Dad replied, "There's no time like the present."61.What did Steven do after Dad agreed?A.He opened all his presents. B.He received the most presents.C.He tried out his new sled. D.He went back to school.62.Where did Steven see Kevin on the second day?A.Under his bedroom window.

A.Because Kevin took it away. B.Because Steven's dad put it away. C.Because Steve's dad lost it. D.Because Kevin lent it to others. 65.How did Steven feel after hearing his dad's words?A.Confident. B.Satisfied. C.Excited. D.Regretful.EThe deer (鹿) is the king of the woods. The deer is one of the largest woodland animals, but it is so shy that you might find it hard to really spot one. During the day, deer hide in the high grass quietly, listening for any noise and ready to run away at the first sign of danger. Nighttime is when deer really get active. They move around all the time in search of grass and other plants to eat. They can run as far as 60 km in one night! Female (雌性的) deer live in groups with their young, while males (雄鹿) prefer to be on their own or with other males.But in the autumn, things change. The woods are full of the sounds of male deer. They let out sounds to draw females’ attention and to let other males know that they are ready to fight over the female deer. Male deer fight each other with their antlers (鹿角).A baby deer is called a fawn (幼鹿). The coat of a newborn fawn is covered in pretty white spots (斑点) that disappear as it gets older. The mother deer watches over her babies and bravely protects them from dangers. Although female deer don't have antlers, they fight off other animals by kicking!A male deer's antlers carry on growing all his life. A ten-year-old deer's antlers can have more than 10 branches (分枝) and weigh 20 kg each. Every spring, the antlers drop off and an even larger set will take their place. You can tell how old a deer is by counting the number of branches on his antlers. The more branches it has, the older the deer is.66.In Paragraph 1, the word "spot" has the closest meaning to "________".A.make B.hurt C.raise D.see67.What do the deer do at night?A.Look for food.

It uses gaming technologies to show the historical scenes of the Library Cave in the digital world.The Library Cave in Mogao Grottoes was discovered in 1900, with more than 60,000 cultural relics unearthed. It was one of the most important archaeological discoveries in the 20th century.On the platform, visitors can role-play and "time travel" to ancient dynasties and talk with eight historical figures. The public can enter the platform through the Digital Dunhuang website and its WeChat mini program."In the digital age, the model of 'culture + technology' has been introduced to promote the development of Chinese culture. The digitalization rate of China's precious cultural relics is over 70%, " according to iResearch.Institutions such as the Palace Museum have also started online digital services of their own.AI technology allows the public to view the interior of the buildings through the Palace Museum's WeChat mini program.The Ministry of Culture and Tourism has also encouraged the development and transformation of culture by digital means. The CCTV has created a series of digital collections with different Dunhuang themes, such as the divine deer, Youyou. It was created based on the image of the nine-colored deer from Dunhuang murals (壁画) ."Digital collections are welcomed among young people, who grow up in the information age. They not only protect the cultural intellectual property (知识产权) but also bring the public closer to China's 'excellent traditional culture'," noted Dunhuang Art Institute.Su Bomin, director of the Dunhuang Academy, told Xinhua that more efforts will be made to explore new forms for showing cultural relics and offering the public greater cultural experiences in the future.4.What can we know about the virtual copy of the Mogao Grottoes' Library Cave?A.The Dunhuang Academy developed it secretly.B.Both time-traveling and gaming technologies were used in it.C.It was discovered in the 20th century with more than 60,000 cultural relics.D.People can have access to it through the Wechat mini program of Digital Dunhuang 5.According to iResearch, what has the model "culture+technology" been applied for?A.Showing the latest technologies in China.B.Helping cultural institutions make a profitC.Pushing the development of Chinese culture.D.Encouraging young people to explore Chinese cultural relics.6.How does the author introduce the success of digital collections in Paragraph 7?A.By listing numbers.B.By giving examples.C.By giving definitions.D.By making comparisons.7.Which of the following best expresses the main idea of the passage?A.China's new way in rebuilding Mogao Grottoes' Library Cave.B.China's interactive digital platform in developing Dunhuang culture.C.China's success in promoting the digitization rate of cultural relics.D.China's latest advances in the development of cultural intellectual property.Research led by an ecologist Bart Hoekstra shows that birds are affected by the mass use of fireworks on New Year's Eve.The research studied how many birds take off immediately after the start of the fireworks, at what distance from fireworks this occurs and which species groups mainly react. "Birds take off as a result of an acute flight response due to sudden noise and light. Wealready knew that many water birds react strongly, but now we also see the effect on other birds throughout the Netherlands, "says Bart Hoekstra.Last year, a study discovered that geese are so affected by fireworks that they spend about 10% longer looking for food than normal during at least the next 12 days. They apparently need time to restore their energy to their former condition, after escaping from the fireworks.Because 62% of all birds in the Netherlands live within a radius (半径) of 2.5 km of inhabited areas (居民区) , the effects of fireworks are high for all birds throughout the country. "Flying requires a lot of energy, so ideally birds should be disturbed as little as possible during the cold winter months. Measures to ensure this are especially important in open areas such as grasslands, where many larger birds spend the winter. The effects ofbirds live there, which are less likely to fly away from disturbance, " says Bart Hoekstra.People who argue for fireworks-free zones in areas where large birds live advise that fireworks should mainly be lit as far away from birds as possible. It would be best for birds if people try to use light shows without sound, such as drone (无人机) shows instead of fireworks.8.How many aspects did the research mainly study?A.One.B.Two.C.Three.D.Four.9.If geese normally spend 10 days looking for food, how long will they spend after escaping from the fireworks according to the study in Paragraph 3?A.About 11 days.B.About 12 days.C.About 13 days.D.About 14 days.10.What does the underlined word "pronounced" in Paragraph 4 mean?A.Adaptable.B.Noticeable.C.Admirable.D.Avoidable.11.What can be the best title for the passage?A.Anxious in The Air!B.Amazing Fireworks-free Zones!C.Fireworks in The World!D.Birds Throughout The Country!Coming into the town of Santa Catarina Palopó, in the highlands of Lake Atitlán in Guatemala, the first thing you notice is the bright colors. Most of the buildings along the main street are eye-catching, in deep, varied hues of blues and greens; interspersed with red and yellow to form complex patterns and designs.Santa Catarina Palopó was once a sleepy town of 5,000 people, most of them indigenous (土著的) and dependent on agricultural work. As agriculture began to dry up here, decline for the town and poverty for many of its families came. To deal with poverty and stimulate economic growth through tourism, a small but mighty group of laborers, artisans, domestic workers and stay-at-home moms created the Pintando Santa Catarina Palopó project.The project was initially to paint all 850 homes and buildings in bright colors, in an effort to change the hillside town into a work of art. "We wanted to paint the houses with colors and figures that represent the community, says the project's executive director Stephany Blanco." A range of designs were created so that families can choose designs for their house that are representative of the family.One of the most representative characteristics of the region is the blue huipil, a traditional blouse which has been worn prominently by local women since the 16th century. That deep sky blue was chosen as the primary color for the Pintando project, with secondary colors found in the sunsets and the nearby lake to make the design more attractive. As for the designs that would be used, they would also find inspiration in local culture, symbols such as volcanoes, flowers, Mayan-styled butterflies and the national bird of Guatemala.Each week, local artists, community members and tourists pick up paintbrushes to make buildings colorful. "At first, the idea of the project left many unsure about participating, but now you can see a considerable difference in the town, "Melissa Whitbeck said. "The color of the buildings is believed to improve the quality of life of the people. It uplifts the people's mood and encourages them to be proud of where they come from."12.What problem did Santa Catarina Palopó face?A.A labor shortage.B.

This would be her most important piano performance yet. At ten years old, she was the youngest performer in the recital. She had practiced playing her song more than 30 times that week. When she closed her eyes at night, the music played over and over again in her head.Now that the day had arrived, Deisha was not sure she was ready. She smoothed her hair andpicked a piece of lint from the new dress that her mother had bought for her. She noticed that her hands were shaking. How could she play the notes of the song if her hands were shaking? She tried to concentrate on steadying them, but they only shook more.Deisha’s piano teacher, Ms Neal, walked up to speak to her. “I have something for you,” she said, putt ing a smooth black stone into Deisha’s hand. “It’s a special stone. There’s no other one like it in the world. You’ve practiced so much, you don’t need anything else.”The stage lights reflected off the rock. “Thank you,” Deisha said.When Deisha’s n ame was called, she rubbed the stone, stepped onto the stage, and played better than ever. After her performance, she noticed that Ms Neal had a whole bag of black stones. “Why did you say this one was so special?” she asked.Her teacher responded, “Because, like your talent, it belongs only to you.”21.Why did Deisha hear the piano music in her head at night?A. She had practiced many times.B. She wanted to remember the song forever.C. She listened to the song every day.D. She liked this piece of music very much.22.Before the performance began, Deisha __________.A. was dissatisfied with her new dressB. waited impatiently backstageC. was too nervous to keep her hands steadyD. forgot the notes suddenly23.According to the text, Ms Neal thought that ________.A. Deisha was fully prepared for the recitalB. it was difficult to play the pianoC. it took talent to play the pianoD. Deisha owned many thingsBMost city parks are places where you can escape from big, ugly structures of metal and stone. The Manhattan High Line is different. Raised 25 feet above the ground, this large metal structure once supported a rail line. The line opened in 1934 to bring trains directly into factories. It was hardly used after the 1960s, and much of it was torn down. However, one part remained in a region of Manhattan called Chelsea. Chelsea was becoming high-class as restaurants, art galleriesknew that at some time, it would have to be removed.But the High Line was not destroyed. In fact, now the old rail line serves as one of the most peaceful places in the city. It holds an elevated park, with beautiful gardens and great views of the city. The idea to turn the rail line into a park came from Joshua David and Robert Hammond. In 1999, they attended a community meeting to decide how to deal with the High Line. David and Hammond were the only people at the meeting interested in saving the historical structure. Later on, when they asked railway officials to take them up to look at the High Line, they saw a mile and a half of wild flowers growing in the middle of the city, and they realized that the High Line had potential to become a park. There was growing interest in improving city centers, and so the project quickly developed and money for construction was easily collected.The first section of the High Line opened in 2009 and immediately became popular with tourists and locals alike. Each part of the park has a different atmosphere. Some areas are like balconies with wonderful city views. Where the rail line goes between buildings, trees are thickly planted. Other sections have wide lawns and walkways planted with wild flowers. Only the final section remains the way it has been for the last fifty years.24. What is the text mainly about?A.A park.B. A train line.C. City transport.D. A historical monument.25. The underlined part “ a dead weight” in Paragraph 1 means _______.A. something with potential to be betterB. something with historical interestC. something useless which slows progressD. something which is a danger to people26. Why w ere people easily persuaded by David and Hammond’s idea?A.They knew the project would bring much money.B.They wanted to see the wild flowers too.C.They realized the High Line was historically important.D.They wanted to make cities nicer places.CThe oceans have a plastic rubbish problem, and it's growing by 8million tons a year. Three years ago, a Dutch teenager named Boyan Slat designed a solution: an ocean rubbish collection device (设备) that would collect ocean plastic without harming ocean life.These days, Slat is anxious to put his ocean-cleaning idea to the test. A Passing grade might lead to the removal of nearly half of plastic rubbish floating in the Pacific Ocean. But the process needs to be tested in real-world conditions before it can be fully started -or beat the criticism of scientists who are doubtful that if can work.Slat's idea is opposite to existing oceanic cleanup methods: Instead of sending ships out to run after floating rubbish, position a fixed, floating, v-shaped buffer(缓冲物) in the ocean so that water moves through it, funneling(流经漏斗状空间) plastic rubbish into a container while allowing animals to swim past the net- free device.To test the idea, Slat and his company, Ocean Cleanup, plan to place a 6. 56l-foot-long float in the Korea Strait, by spring 2016. If realized, it would be the largest floating structure ever used. If the technology works, Ocean Cleanup hopes to build a 62-mile-long system that would float somewhere between Hawaii and California. This one would be big enough to deal with an area containing millions of tons of plastic rubbish.When it first conquered the Internet in 2013, Slats plan caught hearts around the world. But the scientific community doubts whether it would work, how effective it would be, and its possible environmental influence. Slat and the 100-member staff of his company, Ocean Cleanup, answered last year with a 530-page report stating that a 62-mile-long model would remove 42 percent of the plastics in the Pacific Ocean in less than 10 years.27. Boyan Slat invented the device to ____________.A. remove ocean plasticB. catch scientists attentionC. protect the ocean lifeD. beat the criticism of other teenagers.28. What can we infer about slat's invention?A. It changes its position with the windB. It collects rubbish with some nets.C. It works mainly with the v-shaped buffer.D. It uses funnels to control the floating plastic.29. What can we learn from the text?A. Slat tested the device in the Korea StraitB. Slat's device works well in the Pacific OceanC. Ocean Cleanup built a 62-mile-long floating structure.D. Ocean Cleanup needs to prove the value of its new device.30. What is the scientific community's attitude towards Slats invention:A Supportive. B. Doubtful C. Disapproving. D Objective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。
