According to the market research company Mintel, sales have almost tripled over the past five years. While ebikes have become increasingly commonplace, they are still undeniably expensive. You can pick up a perfectly adequate pushbike for £300, but most ebikes cost over £2,000. Now, Cycling Electric, designed to help consumers choose an ebike, offers the following recommendations. 英语学科 第 页 共 10 页4 Best folding bike Carbo Model X Price: £ 2,799|Weight: 13.3kg Range: up to 34 miles This is one of the most convenient bikes, from a little-known label. The lightweight Carbo X is the perfect example of convenience thanks to its carbon frame and belt drive, instead of a metal bike chain. This makes it lighter and less likely to get messy than an electric Brompton, with its more traditional, oily chain. Most stylish Temple Cycles Classic Price: from £ 2,995|Weight: 19kg Range: up to 74 miles This Bristol-based brand is known for its elegant pushbikes, which are hand-built in the city. This is its electric version. It’s a very sleek and functional commuter option and not too heavy. Temples have fewer proprietary (品牌专卖的 ) parts and so are serviceable in any bike shop. Stylish as they may be, the VanMoofs and the Cowboys can be a bit more complex to get back-up and service. The money-no-object option Riese & Müller Nevo4 GT Vario GX Price: £ 5,380|Weight: 28. 4kg Range: up to 93 miles This is a prime example of the attention to detail delivering a high-quality experience in functionality, comfort and practicality — if you can afford it. It has the capacity to handle 25kg of luggage in a pannier, powerful road lights and a beautifully smooth motor. 21. What is the advantage of the Temples over other stylish ebike brands? A. They are more light weight. B. They are more comfortable. C. They have more functions. D. They have easier access to service. 22. Which ebike will a consumer probably choose, who cares most about an excellent experience? A. Carbo Model X. B. Riese & Müller Nevo4 GT Vario GX. C. Temple Cycles Classic. D.The VanMoofs and the Cowboys. 英语学科 第 页 共 10 页5 23. Where is the text probably taken from? A. A magazine column. B. A store advertisement. C. An official document. D. A market research report. B Fighting through pain after running for 28 hours, and amid the sound of tired feet struggling through the Arizona dirt—finally soft, soothing (舒缓的 ) music could be heard over the horizon. The finish line, which was once 100 miles away, was right in front of him. A small, roaring human victory tunnel welcomed Zach Bates as he ran across the finish line. Diagnosed with autism (自闭症) at the age of four, Bates completed the 100-mile ultramarathon (超级马拉松 ) earlier this year, becoming the youngest finisher in the race’s history, aged 19. Bates was a member of the cross-country team in high school but, after graduating he surprised his family with a new goal—to run a 100-mile race before his 20th birthday. Neither Bates nor his parents had any previous experience in preparing for the task at hand, but Brian, his father, found ways to help, truly making it a family affair. In addition to hiking safe trails, they read books together, organized all his nutrition, and made sure their son had the right equipment—like the watch he wore on long runs so they could track him and make sure he was safe and on course. Rana and Brian even helped with training schedules before finding more experienced ultramarathon runners—such as mentor John Hendrix and coach Nickademus de la Rosa. With Hendrix and de la Rosa’s expertise, the young American prepared by competing in shorter distances and successfully worked his way up to the 100-miler in a short time. Rather than having his autism be a reason to make the goal unreachable, his mom said the challenge has helped him stay focused. “If we listen to our children and allow them to do what they want to do and be a support to them, you’ll be so surprised at where they’ll end up,” Rana says. 24. How did Bates probably feel when he ran across the finish line? A. Painful but peaceful B. Tired but cheerful C. Proud and overconfident D. Comfortable and relaxed 25. Why did Bates’ new goal surprise his family? A. Because he was diagnosed with autism. B. Because he was across-country team member. C. Because they considered the new goal impractical. 英语学科 第 页 共 10 页6 D. Because it didn’t take long before he graduated from high school. 26. Which of the following did not contribute to Bates’ success? A. Encouragement of team members B. His perseverance to the goal C. Support from his family D. Guidance from experts 27. What can we learn from the story? A. Birds of a feather flock together. B. Impossible is nothing. C. All’s well that ends well. D. Much will have more. C A promotion(促销) offering 98 yuan domestic plane tickets is being advertised by Chinese online travel platform LY.COM. While such a low price sounds amazing, there is just one catch: The purchaser is not told where the flight is heading, nor when it will take off. The promotion has become a trending topic on Chinese social media as some people have been attempting to book them ahead of the upcoming May Day holiday. Labeled as a “destination blind box” on the site, tickets are purchased through a rather hassle-less booking procedure, in which passengers provide their travel information, select a departure airport and then pay their 98 yuan. If the randomly chosen date and destination are unsuitable, users may ask for a refund, but once they “lock in” their tickets, there is no going back. “Destination blind box” is now a hot topic on China’s online platforms. “I believe young people are a big target demographic (特定年龄段人口 ) for this promotion, because they not only enjoy the thrill of the unknown, but also like to show off their lives through these types of commercial activities. Like this one for instance, it doesn’t matter if they finally go or not. Booking a ticket and posting about it on social media can still suggest that one has adventurous and life-loving qualities,” said Fan, a marketing expert who has worked with civil aviation (航空) clients. Many people not only shared the screenshots of tickets they drew, some even came up with a tutorial to teach the booking procedure under the free cancelling policy. However, some others claimed it is too rare to draw a ticket that is ideal. “If it wants to be a profitable activity, the release of the tickets must have been planned ahead and is not as random as it seems. It will not have popular airlines. The marketing campaign may also be aimed at the fast sale of some tickets from less popular airlines that were originally not that expensive. If they sell a large quantity of tickets, the company may still earn a profit even though the price is 98 yuan,” an expert in tourism suggested. 英语学科 第 页 共 10 页7 28. Which of the following best explains “catch” underlined in paragraph 1? A. Benefit. B. Disadvantage. C. Mistake. D. Charm. 29. What is paragraph 2 mainly about? A. The origin of “destination blind box”. B. The popularity of “destination blind box”. C. The original purpose of “destination blind box”. D. The purchase introduction to “destination blind box”. 30. Why will “destination blind box” appeal to young people according to Fan? A. It agrees with their lifestyle and attitudes. B. It allows them to experience various adventures. C. It satisfies their desire to travel around China. D. It helps them save money on the cost of travel. 31. What can we infer about the promotion from the last paragraph? A. It makes it easy to get an ideal ticket. B. It still needs to be improved. C. It will not bring in any profit. D. It will give a boost to tourism. D According to the Solar Energy Industry Association, the number of solar panels installed(安装)has grown rapidly in the past decade, and it has to grow even faster to meet climate goals. But all of that growth will take up a lot of space, and though more and more people accept the concept of solar energy, few like large solar panels to be installed near them. Solar developers want to put up panels as quickly and cheaply as possible, so they haven’t given much thought to what they put under them. Often, they’ll end up filling the area with small stones and using chemicals to control weeds. The result is that many communities, especially in farming regions, see solar farms as destroyers of the soil. “Solar projects need to be good neighbors,” says Jordan Macknick, the head of the Innovative Site Preparation and Impact Reductions on the Environment(InSPIRE) project. “They need to be protectors of the land and contribute to the agricultural economy.” InSPIRE is investigating practical approaches to “low-impact” solar development, which focuses on establishing and operating solar farms in a way that is kinder to the land. One of the easiest low-impact solar strategies is providing habitat for pollinators(传粉昆虫). Habitat loss, pesticide use, and climate change have caused dramatic declines in pollinator populations over the past couple of decades, which has damaged the U.S. 英语学科 第 页 共 10 页8 agricultural economy. Over 28 states have passed laws related to pollinator habitat protection and pesticide use. Conservation organizations put out pollinator-friendliness guidelines for home gardens, businesses, schools, cities—and now there are guidelines for solar farms. Over the past few years, many solar farm developers have transformed the space under their solar panels into a shelter for various kinds of pollinators, resulting in soil improvement and carbon reduction. “These pollinator-friendly solar farms can have a valuable impact on everything that’s going on in the landscape,” says Macknick. 32. What do solar developers often ignore? A. The decline in the demand for solar energy. B. The negative impact of installing solar panels. C. The rising labor cost of building solar farms. D. The most recent advances in solar technology. 33. What does InSPIRE aim to do? A. Improve the productivity of local farms. B. Invent new methods for controlling weeds. C. Make solar projects environmentally friendly. D. Promote the use of solar energy in rural areas. 34. What is the purpose of the laws mentioned in paragraph 4? A. To conserve pollinators. B. To restrict solar development. C. To diversify the economy. D. To ensure the supply of energy. 35. Which of the following is the best title for the text? A. Pollinators: To Leave or to Stay B. Solar Energy: Hope for the Future C. InSPIRE: A Leader in Agriculture D. Solar Farms: A New Development 第二节(共 5小题;每小题 2.5分,满分 12.5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。选项中有两项为 多余选项。 Learning how to apologize is similar to learning any new behavior. It may feel awkward and may not be polished at first. 36 There are several tips that will help you as you learn how to apologize. 英语学科 第 页 共 10 页9 First of all, wait until the right time and you are in the right place. Although public apology is often appropriate, discretion (谨慎 ) should be used. 37 Remember, you will be raising a topic that may recall a bad experience or bad feelings. Be respectful as you approach this task. Be direct and brief in your approach. Acknowledge the fact that injury has occurred and then take responsibility for what happened. Be sincere in expressing your regret and demonstrate your willingness to take ownership of the situation. 38 . Even if you follow these steps, be prepared for rejection. Sometimes, the person apologizing has an expectation that the apology will lead to immediate forgiveness and acceptance. 39 If you think of the offense (冒犯) as an emotional bruise (瘀伤), think of the healing process as the color changes we see as a bruise heals. 40 Knowing when to keep one’s mouth shut is a virtue. Keeping quiet may be very difficult, as post-apology listening is not easy. We may hear unpleasant observations from another about our own shortcomings. We may hear the expression of anger. One of the ways we let others know we are truly responsible and accountable for our mistakes is by listening to the other party pour out the feelings associated with our actions. A. Forgiveness and acceptance may take time. B. To give or receive a good apology is an art. C. But with practice, everyone can learn to do it. D. Listening to the response to our apologies is important. E. Most apologies can and should happen in a private setting. F. In other words, avoid excuses and offer to repair the damage. G. Taking responsibility doesn’t mean accepting blame for everything. 第三部分 语言运用(共两节,满分 30分) 第一节(共 15小题;每小题 1分,满分 15分) 阅读下面短文,从每题所给的 A、B、C、D四个选项中选出可以填入空白处的最佳 选项。 On Oct. 11, hundreds of runners competed in a cross-country race in Minnesota.
