2019-2020学年佛山市顺德区龙江中学高三英语第一次联考试卷及答案解析
2019-2020学年佛山市顺德区龙江中学高三英语第一次联考试卷及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项AChildren under the age of 18 will be allowed up to three hours per week to play video games, according to a notice issued by China's National Press and Publication Administration. Online game companies are required to provide services to minors — from8 to 9 p. m. on Fridays, Saturdays, Sundays and legal holidays — as a way to safeguard their physical and mental health. Children are playing more and more online games these days. Is it time to limit their online gaming time? What role do parents have? Readers share their opinions.RizlaredOnline games are addictive, but if children are taught how to manage in a sensible and responsible manner then it is no longer a threat(威胁).To achieve this, parents need to set examples for not being glued to their phones. Teaching is and always will be the best solution to such problems.AndrewGood policy. By limiting time spent on online games, kids can spend time doing more useful things to develop their potential. They can go outside and run, jump and swim instead of sitting on a couch at home and playing with a smart phone.AdamIt is often seen that parents argue with children over cellphones. Most parents can hardly set and enforce the time limit for its daily usage. Some forcibly take away their cellphones, but it will ruin trust and relationship. Even worse, it will make their kids hate them.PinkExcessive(过度的）gaming is purely a waste of time and energy for minors and has a negative effect on both physical and mental health. The gaming industry should not put profit- flaking interests as its priority (优先事项) . They should act in a socially responsible way toprovide an environment for children to ensure their well-being and development.LaurenThere would be a loophole(漏洞). Children could use their parents’ or other adults’ IDs to avoid real-nameregistration, thus making it impossible to put this policy in effect. Parents ly need to strengthen guidance and supervision to keep their children from gaming addiction.1. What should kids do according to Andrew?A. Play online games.B. Play with a smart phone.C. Study all the time.D. Go in for outside activities.2. What does Pink advise the gaming industry to do?A. Pay attention to its profit.B. Focus on kids’ health.C.

They set examples for their kids.C. They limit their kids’ time.D. They blame kids for addiction.BGlobal food demand will double by 2050, according to a new projection, and the farming techniques used to meet that unprecedented(空前的) demand will significantly determine how severe the impact is on the environment, researchers said.The study researchers warned that meeting the demand for food would clear more land, increase nitrogen(氮) use and significantly add to carbon dioxide and other greenhouse gas emissions.“Agriculture’s greenhouse gas emissions could double by2050 if current trends in global food production continue,” study researcher David Tilman, of theUniversityofMinnesota, said in a statement. “This would be a major problem, since global agriculture already accounts for a third of all greenhouse gas emissions.”The researchers studied various ways in which the increasing food demand could be mentioned. They found that the most environmentally friendly and cost-effective approach would be for more food producers to adopt the nitrogen-efficient “intensive” farming method, which involves the heavy use of labor and the production of more crops per acre.This approach was shown to be more effective than the “extensive” farming currently practiced by many poor nations, a method that includes clearing more new land to produce more food.Different farming methods produce significantly different yields, the researchers found — in 2005, the crop yields for the wealthiest nations were more than 300 percent higher than what the poorest nations produced.According to their analysis of the effects of extensive farming, if poorer nations continue using this method, by 2050theywill have cleared an area larger than theUnited States, about 2.5 billion acres. However, if wealthynations help poorer nations to improve food yields by incorporating(吸收) intensive farming practices, that number could be reduced to half a billion acres.The researchers stress that the environmental effects of meeting future food demand depend on how global agriculture expands and develops.“Our analyses show that we cansave most of the Earth’s remaining ecosystems by helping the poorer nations of the world feed themselves,” Tilman said.4. What is the best title of this passage?A. The World Will Need Double Food by 2050B. Man Will Face the Risk of Lacking Food in the FutureC. Future Farmers Hold Environment’s Fate in Their HandsD. Different Farming Methods Produce Significantly Different Yields5. The character of the extensive farming is ________.A. very cost-effectiveB. to produce more crops per acreC. at cost of more new land to produce more foodD. very environmentally friendly6. It can be inferred from the passage that ________.A. poorer nations mainly use the intensive farmingB. wealthy nations mainly use the extensive farmingC. the intensive farming needs less food producersD. the extensive farming has a worse effect on ecosystems7. According to the passage, the underlined word “they” in the 7th paragraph refers to “________”.A. poorer nationsB. the effects of extensive farmingC. wealthy nationsD.future food demandCAfter a year at sea, 16-year-old Laura Dekker can finally say, “Missionaccomplished!” Last month, she finished a daring trip around the world aboard her 38-foot boat, Guppy. Dekker, who is from theNetherlands, traveled more than 30,000 miles all by herself. She is the youngest person ever to sail around the globe alone.Dekker had wanted to lake on this challenge when she was even younger. She first tried to set sail at the age of 13, but a court in theNetherlandsstopped her. They said that she was too young to make such a risky trip by herself. But Dekker insisted she had the navigation skills and patience of an adult sailor.She finally took off on January 20, 2011. During her trip, Dekker battled loneliness, storms, and worries about pirates. But she also got to surf, scuba dive, and started a new hobby: playing the flute. Although Dekker didn’t spend all of her time at sea—she stopped at ports along the way—she did spend her 16lh birthday on the open ocean. To celebrate, she ate doughnuts for breakfast.But Dekker didn’t sail into the record books. Guinness World Records and the World Sailing Speed Record Council no longer recognize records for “youngest” sailors. They dropped the category in 2009 to discourage children fromattempting such dangerous feats (壮举). But that didn’t stop Dekker，who was born on a yacht during a seven-year world voyage undertaken by her parents.Dekker doesn’t mind that she won’t hold an official record. She says it was a personal goal, and she is happy she achieved it.“I am not disappointed at all that Guinness World Record won’t recognize my attempt.” Dekker wrote on her website. “I did not start on my trip to achieve any record…I did it just for myself.”8. Dekker wasn’t allowed to sail at the age of 13 because .A. people were concerned about her safetyB.she didn’t learn any sailing skills wellC. she had to continue her study at schoolD. she didn’t have enough patience for long trips9. What does the underlined word “accomplished” in Paragraph 1 mean?A. Failed.B. Completed.C. Continued.D. Started.10. In 2009 records for youngest sailors were canceled in order to .A. set a higher sailing standard for teen sailorsB. stop children entering Guinness World RecordsC. encourage parents to sail with their childrenD. prevent children making dangerous attempts11. What could be the best title for this passage?A. A New Guinness World Record in SailingB. A New Sailing Standard for Teen SailorsC. A Teen Girl Sailing Alone Aroundthe WorldD. The Youngest Sailor in Guinness World RecordsDAs one of the world’smost popular cultural mediums, cinema is at the leading position at the Taihu World Cultural Forum(论坛), an annual event that aims to improve cultural exchanges. So far this year, Chinese box office has already topped 58 billion yuan, the China Film Administration said. This indicates that China, the world’s second-largest movie market, is closing the gap with the United States, the world’s top cinema market.Cao Yin, director of the program center at China Movie Channel, said that China has 67,000 cinema screens. the most of any country, and the number is expected to increase to 80,000 by the end of next year. Saying that China has signed coproduction agreements with 22 countries (including the United States, Canada, Japan. India etc.) ,Cao added it has deepened cinematic exchanges between Chinese filmmakers and their foreign counterparts (同行).With the country’s huge native market, which produced more than 1,000 films in 2019, Hong Kong director Stanley Tong said he believes foreign filmmakers will increasingly seek cooperation with China. “International coproduction will become an important platform to send Chinese stories oversea and give us a broader vision of creation,” Tong said.Recently, over 80 percent of the world’s top 100 highest box-office titles have been action films. Tong said the films, in which plots are basically secondary to shining stunts (特技), is one of the easiest ways to appeal to foreign audiences. But it has been a decades-long struggle for Chinese filmmakers to sell their stories overseas. When asked what kinds of Chinese films would have the most global appeal. Yan Zhaozhu, chairman of the Taihu World Cultural Forum, said stories that address universal issues, such as environmental protection and climate change, are perhaps the best options.12. What is the purpose of the Taihu World Cultural Forum?A. To strengthen cultural exchanges.B. To build more cinemas in China.C. To invite more tourists to Taihu.D. To attract more international investment.13. What can we infer about Cao Yin’s opinion in Paragraph 2?A. Chinese box office has already overtaken the United States so farB. The screens of Chinese cinemas will be world-leading in the futureC. China has signed the most coproduction agreements with other countriesD. There will be more and more cooperations between Chinese filmmakers and other countries.14. How do Chinese filmmakers feel about selling their movies to the world right now?A. Easy.B. Disappointed.C. Challenged.D. Confused.15. What is the best title for the text?A. Box Office: Unclear FutureB. China: Top Second Movie MarketC. Cinema: The Leading Cultural PositionD. Chinese Filmmakers: Severe Competition Situation第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

I still remember the day in high school that my mom forgot to pick me up from school. I’m the oldest of four children, and no doubt she’d had a long day with the other kids and it’d slipped her mind. After waiting at school for an hour, I walked the three miles home, and when I got to my house, I shut our front door with anger, stormed into the kitchen and screamed in my mom’s face that she’d forgotten me.Later that night, my dad told me I no longer had a ride to school the next day. I figured my mom would still take me, but when the morning came, she refused. It was midterm, and as a straight-A student ready to start college applications, being late wasn’t an option (选择). In my mind, missing these tests would have been the end of my academic career. I begged my mom. I told her she was ruining my future and everything I’d worked for. But sheheld her ground, and that day, I walked to school. And I missed my tests.My mom didn’t rescue me from failure. She let me suffer from it. She let me figure it out. She let me learn. Now, as a mom myself, I’ve realized that I want my kids to experience failure because failure is how we grow, learn and think outside of ourselves. It’s how we self-educate to learn what’s right and respectable, and what’s not. It’s how we become responsible and enthusiastic. Falling down makes us better because we learn how to get up.4.

I'd waited my entire life to see this great French architecture, and experienced it in its full glory on a bright sunny day. Last night, I again cried for the centuries-old church while watching it burn.I hadn't expected to spend my evening that way. My friend and I were having dinner at a cafe a block or so away from the Notre Dame, choosing to skip going inside with the intention to go back the next day.However, we heard that it caught fire, so we left the cafe and ran towards the church, following heavy smoke from it, and soon we joined a nearly silent crowd. Some were praying, some were crying, but most were staring in disbelief at the disaster happening before us. The fire continued to get worse. About 400 firefighters were working to control the fire. We could see their flashlights shining as they inspected the front from a balcony.The Notre Dame is part of the heartbeat ofParis, I reflected on the experiences I've had there, from attending a bread market out front to admiring the beautiful windows and architecture inside. It is a spot that helps makeParismagical. And here we were, watching it burn down. It was too much to handle, but it was impossible to look away.About 9：30 pm, the gathered crowd spontaneously（自发地）began to sing Hymns（圣歌）to the church. We sang along with the group, feeling at once less like tourists and more like members of them. I hadn't imagined all that before.For hundreds of years, the Notre Dame hasseen the most joyous and the most terrible moments in the lives of both France and her people.

2020年佛山顺德区龙江实验学校高三英语一模试卷及答案解析第一部分阅读（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项ASan Francisco Bay Area is a great place if you're a sports fan as you'll find several events all year round and plenty of team pride. If you are anywhere close to the area during a game,these fantastic sports events are here for you.San Francisco Giants BaseballThe San Francisco Giants baseball team plays in SF at Oracle Park. This is a fun ballpark because it's always packed with great energy and offers views of the bay. It's one of the most popular San Francisco sports events. The Giants are part of the National League West Division. Since their arrival here in 1958,they have been World Series Champions three times.Golden State Warriors BasketballThe fan base of the Golden State Warriors distributes the whole San Francisco Bay Area as this region's only NBA team.Their regular season runs from late October through mid-April, and all home games are played at the Chase Center in San Francisco.In total, the Warriors has won six NBA championships.San Francisco 49ers FootballThe 49ers are San Francisco's NFL team, though they have recently moved to Levi's Stadium in Santa Clara, about an hour south of SF. The football team was named for the prospectors (探矿者) who arrived in the area in 1849 for the Gold Rush. They’ve won 5 Super Bowl championships, all between 1981 and 1994.San Jose Sharks HockeyThe San Jose Sharks represent the Bay Area in hockey (冰球).They were founded in 1991 as the only Bay Area team to compete in the NHL. Sharks fans love going to these San Francisco sports events at the SAP Center,which they call the Shark Tank,located about an hour southeast of SF.1.Where can a sports fan have a good view of the area?A.The Oracle Park.B.The Chase Center.C.Levi's Stadium.D.The SAP Center2.Which team has claimed the most titles according to the text?A.The Giants.B.The Golden State Warriors.C.The 49ers.D.The San Jose Sharks.3.Where is the passage probably taken from?A.A book review.B.A news report.C.A science fiction.D.A tourist magazine.BAccording to statistics published by the BPI (Buying Power Index) a couple of months ago, digital streaming (流媒体) now accounts for 80 percent of the music consumption in the UK. Despite the incredible growth of online streaming platforms like iTunes, Apple Music and Tidal over the past 15 years, a more traditional medium has also seen a return of interest and sales in the music industry. In 2020, almost one in five of all albums purchased in the UK is vinyl (黑胶唱片), and it has once again become the most popular physical musical medium.With digital streaming so easy and convenient, why are so many peopledrawn to traditional records? Some experts claim that vinyl is a physical medium for experiencing music, something tangible (有形的) to hold and own. For most people, having something tangible and interacting with it gives depth to the experience of music. Listening to an album and touching it the way the artist intended can make them feel more connected to the music and the artist. Records are physical products that can be not only displayed but also gifted, shared, traded and passed down through generations.Sound quality is another hot topic. A lot of music lovers feel that the analogue sound (模拟声音) vinyl offers is superior to modern digital audio, particularly with regards to the compressed formats streaming platforms use. There’s a common belief that old-school analogue audio has a warmer, fuller sound than digitised music. For vinyl followers, the very defect traditional recorders often have, such as the familiar crackle (劈啪作响) when the record starts, bring the music to life in a different way.There’s aritualisticaspect to vinyl that a lot of people are drawn to, too. The act of putting a record on—carefully removing the record from the sleeve, placing it on the record player and gently dropping the needle on the right groove (凹槽)—is a more assiduous (一丝不苟的), mindful way of engaging with music. When you’re listening to vinyl, you can’t tap abutton and go about your day while the streaming service provides hours of music. You need to stay close to the record player to move the needle and flip the record over.It’s clear that the vinyl interest is well underway, and vinyl records are truly making a comeback. In an increasingly digital society, there’s something to be said for analogue experiences. Perhaps one of the great things about being alive in the 21st century is our ability to have the best of both worlds—the timeless appeal of physical records alongside the easy access to vast music libraries that streaming offers.4. What are the statistics published by the BPI used to show?A. An increase in music consumption.B. The recovery of music industry.C. A comeback of a physical medium.D. The acceptance of online streaming.5. According to some experts, why does vinyl interest many people?A. It attracts people by its realistic feel.B. It offers simple access to different music.C. It shares a new way to enjoy music.D. It provides people with perfect sound effect.6. The underlined word “ritualistic” in Para.4 means something ______.A. Overlooked by society.B. Updated very frequently.C. Performed as part of a ceremony.D. Kept for a long time without changing.7. How does the writer feel about the future development of music medium?A. Traditional records will get underway.B. The analogue experiences may matter more.C. Vinyl sales will boom with technological advance.D. There should be a good mix of old and new.CWhether for a special holiday, as a way of showing gratitude or just a way of letting someone know you care, gift giving is a universal custom Though the purpose may be similar from place to place, traditions vary widely from one country to the next. A behavior that shows respect in one place might be consideredoffensivesomewhere else. Take a look at unique gifting traditions from around the world.Here in theUS, a set of kitchen knives seems like the perfect gift idea for a wedding. However, in certain European countries likeGermany, people believe that a knife presented as a gift will cut off your friendship. There is a way to break it: Tie a coin to the knife or gift box. The receiver then returns the coin to you as a “payment”to remove the bad luck.There's a well-known Italian wedding tradition where the groom's (新郎) tie is cut into a number of tinypieces. Wedding guests can then "buy” these tie pieces in exchange for cash. It's a fun way to give money to the new couple thatleaves guests with a wedding souvenir.As left hands are considered unclean in Indian culture, behaviors such as touching, passing money, or giving gifts are to be done with the right hand. Different from some other cultures , an odd number (奇数) of thingsor currency represents good luck. For example, £11 should be given rather than £10.InZimbabwe, it is common to directly ask for a gift. When you receive a gift without asking for it, even if the giver's family is poor, it's the worst way to reject the offering. Also, expressing thanks with actions is better than giving thanks orally (口头地).These may include jumping up and down, dancing, or whistling.8. What does the underlined word “offensive“ in paragraph 1 refer to?A. Rude.B. Creative.C. Suitable.D. Caring.9. How do people prevent friendship breaking down when giving gifts like knives?A. The guests cut the groom's tie into pieces.B. The receiver returns the coin to the giver.C. The giver gives gifts with the right hand.D. The receiver expresses thanks by dancing.10. What can we learn about the gift giving inZimbabwe?A. It is not proper to ask for a gift directly.B. It's better to reject a gift from a poor family.C. One can express thanks by writing letters.D. Showing gratitude with actions is better than words.11. Which can be a suitable title for the text?A. The Wayof Showing GratitudeB. A Fun Behavior to Respect PeopleC. Various Gift Giving TraditionsD. A Special Custom of Gift GivingDAs I work in theLarkwhistle Garden in Dyer's Bay, Ontario, I take my time and the garden is teaching me about working with the earth. I recognize that there will be both successes and failures and there are many variables(变量)that affect them both.The quality of the seeds planted has a bearing on how the plants will grow. The weather can be too hot, too cold, or exactly right, and usually varies between all three. Weeds seem to grow in the garden and need to be taken care of, pulled, and removed to ensure they do not eat into the fruits, vegetables, and flowers we have so lovingly planted.I take time to stand back and rest, and to observe the plants and how they are growing. Each plant is unique and develops in the way that is best for them. Some have large broad leaves to shadow their fruit from the severe rays of the sun, while other plants are more open, their fruit needing the light to grow and ripen.Getting my hands dirty, feeling the sweat on my forehead, and the strength and flexibility of my body as I dig, bend and work under the warm summer sun, reminds me I am alive in ways I would not have remembered sitting on the couch.It is attractive to move things around, to transplant, and to disturb the natural order of how plants grow. The garden teaches me that it is important to know when to disturb things and when to let them be. The garden's life cycle follows a pattern that is repeated according to laws of nature, birth, growth, and then dies and it teaches us to accept this fact.12. How many variables may affect the growth of plants in the garden?A. Two.B. Three.C. Four.D. Five.13. What can we learn about the author?A. He feels exhausted while gardening.B. He enjoys life from working practice.C. He takes pleasure in harvesting fruits.D. He dreams away his time in the garden.14. How is the garden tended by the author?A. Its rank grass is got rid of.B. Its plants are left to grow freely.C. Its temperature is controlled properly.D. Its plants with large broad leaves are cut off.15. What fact does the author learn from gardening?A. Life takes its course.B. Hard work benefits health.C. Time is short and precious.D. Gardening brings good harvest.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

里面才低声地问了声：“谁呀？”他听出来，那是钱伯伯的声音。
③“我，瑞全！”他把嘴放在门缝上回答。
④里面很轻很快地开了门。
⑤门洞里漆黑,教瑞全感到点不安。
他一时决定不了是进去还是不进去好。
⑥“老三进来！”钱先生在屋中叫。
瑞全进去，还没坐下，老者就问：“怎样？得烧书？”⑦瑞全的眼向屋中扫视了一圈。
“这些线装书大概可以不遭劫了吧？日本人恨咱们的读书人，更恨读新书的人；旧书或者还不至于惹祸！”⑧“呕！”钱默吟的眼闭了那么一下。
“可是咱们的士兵有许多是不识字的，也用大刀欧日本人的头！对不对？”瑞全笑了一下。
“侵略者要是肯承认别人也是人，也有人性，会发火，他就无法侵略了，日本人始终认为咱们都是狗，踢打着都不哼一声的狗！”⑨“那是个最大的错误！”钱先生的手伸了一下，请客人坐下。
他自己也坐下。
“我是向来不问国家大事的人，因为我不愿谈我所不深懂的事。
可是，有人来亡我的国，我就不能忍受！我可以任着本国的人去发号施令，而不能看着别国的人来做我的管理人！”他的声音还像平日那么低，可是不像平日那么温柔。
楞了一会儿，他把声音放得更低了些，说：“你知道吗，我家老二今天回来啦！”⑩“二哥在哪儿呢？我看看他！”⑪“又走啦！又走啦！”钱先生的语声里似乎含着点什么秘密。
⑫“他说什么来着？”⑬“他？”钱默吟把声音放得极低，几乎像对瑞全耳语，“他来跟我告别！”⑭“他上哪儿？”⑮“不上哪儿！他说，他不再回来了！教我在将来报户口的时候，不要写上他；他不算我家的人了！”钱先生的语声虽低，而眼中发着点平日所没有的光;这点光里含着急切兴奋，还有点骄傲。

The oil and gas industry has forcefully used the technique known as hydraulic fracturing (水力压裂法) to destroy sub-surface rock and liberate the oil and gas hiding there. But the process results in large amounts of chemical-filled waste water. Horizontal drilling (水平钻孔) for oil can also produce large amount of natural, unwanted salt water. The industry deals with this waste water by pumping it into deep wells.On Monday, the US Geological Survey published for the first time an earthquake disaster map covering both natural and “induced” quakes. The map and a report show that parts of the central United States now face a ground-shaking disaster equal to the famously unstable terrain (不稳定地形) of California.Some 7 million people live in places easily attacked by these man-made quakes, the USGS said The list of places at highest risk of man-made earthquakes includes Oklahoma, Kansas, Texas, Arkansas, Colorado, New Mexico, Ohio and Alabama. Most of these earthquakes are ly small, in the range of magnitude (震级) 3, but some have been more powerful, including a magnitude 5.6 earthquake in 2011 in Oklahoma that was connected to waste water filling.Scientists said they do not know ifthere is an upper limit on the magnitude of man-made earthquakes; this is an area of active research Oklahoma has had prehistoric earthquakes as powerful as magnitude 7.It's not immediately clear whether this new research will change industry practices, or even whether it will surprise anyone in the areas of newly supposed danger. In Oklahoma, for example, the natural rate of earthquakes is only one or two a year, but there have been hundreds since hydraulic fracturing and horizontal drilling, with thewaste water filling, became common in the last ten years.4. What kind of human activities can cause earthquakes?A. The man-made produced waste water in the factories.B. The process of digging deep wells in those poor areas.C. The advanced techniques used to deal with waste water.D. The oil or gas industry's work connected with the earth.5. What does the underlined word “induced” in paragraph 2 mean?A. Man-made.B. Reduced.C. Newly-built.D. Controlled.6. How much magnitude can man-made earthquakes reach?A. It's been said as small as magnitude 3.B. It has been said as high as magnitude 7.C. It's being studied without a final conclusion.D. It has risen by an average of magnitude 5. 6.7. What is the best title for the text?A.

More Often Earthquakes as Powerful as Magnitude 7 in AmericaCI am a part of the Windward Robotics team known as the Omnicats, one of the many clubs offered at my school. My eight teammates and I started out by watching the robotics qualifiers and finals of Chinese teams. We used these robotics videos for inspiration and drew up mind maps of what our team wanted to do.We meet every day for two hours after school in order to build our robots. Typically, adultsoverseewhat students are building, but my school lets teens take control. It leaves room for more errors, but we're prouder of our final product.Before our first real match, a practice was offered at the actual site. My sub-team had been further along than other teams but quickly fell behind. When we arrived on that big day, I immediately felt my teammates' nervousness. Our first match was in three minutes. All of us glanced around at each other since we were not prepared at all. Our robot was still sitting in a box. Two of our teammates rushed to take the robot for an officialexamination as the rest of us discussed our strategy (策略).Our team captain explained that we all should try driving the robot now, while it was early in the season. She gave me the remote. I had only driven for a limited amount of time in practice so I was extremely nervous. Our autonomous code (自动代码) beganto run almost immediately after our short discussion. Despite all the drama, we ended up winning the match.Not too bad for the first match! I was so proud. I did not enjoy the pressure of driving but liked building the robot behind the scenes instead.We have transferred to a different type of robotics at the end of the semester, which involves the whole team designing one giant robot with large tools. I am a part of the electrical team now, so I make sure the motherboard (母板) can supply the robot's energy needs. We have all enjoyed the rest of the season and learned that robotics it never dull!8. What does the underlined word in paragraph 2 probably mean?A. InspectB. AdmireC. OverlookD. Assume9. Why did her teammatesfed so nervous before first match?A. Because it was really too difficult for them.B. Because they didn't prepare for it at all.C. Because they didn't know what the match would be like.D. Because they didn't make full preparations before the match.10. How did the author feel about their first robotics match?A. It was tiring but exciting.B. It was stressful but wonderful.C. It was terrible but powerful.D. It was boring but professional11. What is the best title for the text?A. A Girl Who Loves RobotsB. My First Robotics MatchC. Teamwork for RobotsD. Robotics Is Never DullDWolves have a certain undeserved reputation: fierce, dangerous, good forhunting down deer and farmers’ livestock. However, wolves have a softer, more social side, one that has been embraced by a heart-warming new initiative.In a bid to save some of Europe’s last wolves, scientists have explored the willingness of these supposedlyfierce creatures to help others of their kind. Female wolves, the scientists have discovered, make excellent foster parents to wolf cubs that are not their own. The study, published in Zoo Biology, suggests that captive-bred wolfcubs(幼兽)could be placed with wild wolf families, boosting the wild population.The gray wolf was once the world’s most widely distributed mammal, but it became extinct as a result of widespread habitat destruction and the deliberate killing of wolves suspectedof preying on livestock. Fear and hatred of the wolf have since become culturally rooted, fuelled by myths, fables and stories.In Scandinavia, the gray wolf is endangered, the remaining population found by just five animals. As a result, European wolves are severely inbred and have little geneticvariability（变异性）, making them vulnerable to threats, such as outbreaks of disease that they can’t adapt to quickly. So Inger Scharis and Mats Amundin of Linkoping University, in Sweden, started Europe’s first gray wolf-fostering program. They worked with wolves keptat seven zoos across Scandinavia. Eight wolf cubs between four and six days old were removed from their natural parents and placed with other wolf packs in other zoos. The foster mothers accepted the new cubs placed in their midst.The welfare of the foster cubs and the wolves’ natural behavior were monitored using a system of surveillance cameras. The foster cubs had a similar growth rate as their step siblings in the recipient litter, as well as their biological siblings in the source litter. The foster cubs had a better overall survival rate, with 73% surviving until 33 weeks, than their biological siblings left behind, of which 63% survived. That rate of survival is similar to that seen in wild wolf cubs. Scientists believe that wolves can recognize their young, but this study suggests they can only do so once cubs are somewhere between three to seven weeks of age.If captive-bred cubs can be placed with wild-living families, which already have cubs of a similar age, not only will they have a good chance of survival, but they could help dramatically increase the diversity of the wild population, say the researchers. Just like the wild wolves they would join, these foster cubs would need protection from hunting. Their arrival could help preserve the future of one of nature’s most iconic and polarizing animals.12. What’s the theme of the passage?A. Giving wolf cubs a new lifeB. Foster wolf parents and foster cubsC. The fate of wild wolvesD. Changing diversity of wild wolves13. Which of the following flow chart best demonstrates the relationship between the wolves?A. B.C. D.14. Which of the following statements is true?A. Female wolves are willing to raise wolf cubs of 3 to 7 weeks old.B. Foster cubs are accepted by foster parents and are well bred.C. Man’s hostile attitude towards wolves roots in myths, fables and stories.D. Foster cubs and their biological siblings have similar growth rate and survival rate.15. What’s the purpose of the research?A. To help wolves survive various threatsB. To improve wolves’ habitat and stop deliberate killingC. To save endangered wolves by increasing their populationD.

Data was collected on factors including garden typology（类型学）, frequency of gardening and individual awareness of health and well-being."This is the first time the dose response（剂量效应）to gardening has been tested and the evidence from the survey strongly suggests that the more frequently you garden, the greaterthe health benefits," said Royal Horticultural Society (RHS) lead author Dr Lauriane Chalmin-Pui. In fact, gardening every day has the same positive impact on well-being than undertaking regular and powerful exercise like cycling or running.When gardening, our brains are pleasantly entertained by nature around us. Gardening takes our attention away from ourselves and our stresses, therefore, it helps restore our minds and reduce unfavorable feelings.Improving health, however, was not the main motive power to garden, but rather the direct pleasure gardening brought to the participants."Gardening is like effortless exercise because it doesn't feel as exhausting and hard as going to the gym, for example, but we canexpendsimilar amounts of energy," Chalmin-Pui added.Most people say they garden for pleasure and enjoyment, so people who like gardening may be easy to be addicted to it. However, this sometimes may become a piece of good news, from the aspect of mental health. "We hope all the millions of new gardeners will be getting their daily gardening and feeling all the better for it. " Chalmin-Pui said in the interview.4. What can be inferred about gardening from the survey?A. Improving health is the aim of the participants.BGardening makes no difference to health.C. Health benefits from frequent gardening.D. Too much gardening always does harm to health.5. What does the underlined word "expend" mean in paragraph 7?A. Consume.B. Make use of.C. Increase.D. Save.6.

What is Chalmin-Pui's attitude to the new gardeners' gardening?A. Carefree.B. SupportiveC. Tolerant.D. Indifferent.CJoshua Nelson, 18, fromMissouri, is graduating fromSt. CharlesWestHigh Schoolthis week and will be attendingSoutheastMissouriStatein the fall. He had saved upmoney to pay for his tuition, but when he received the college's President's Scholarship, he decided to take his savings and donate it to other students in need.“It comes from my family education and faith," Nelson said. "I've always lived by strong principles as far as being a cheerful giver andhaving an open handwhen it comes to giving back so I feel like that really motivated me.”SEMO's President's Scholarship is the school’s most celebrated, and is only awarded to five top students annually. Nelsonsaid he sat down and outlined how a scholarship could work to help future students who need financial assistance for college. Originally the plan was to give away $ 1,000 the one time, but then he met up with his counselor (顾问), Yolanda Curry, to work outa game plan.“I wasn't expecting it at all!” Curry said. "He told me he had a great idea and wanted to share it with me. I could tell he was really excited.Nelson, in association with his high school, set up the Joshua Nelson Leaders In Action Scholarship fund. Each year, $1,000 will be awarded to a senior. The money will come from donations, of which there have been $16,000 so far — for a total of $17,435 at last count, according to the school. With the money already in the fund, there's enough to give out a scholarship each year for over a decade. The first scholarship was awarded on June 1 to Darrell Montalvo-Luna. As the first recipient, his scholarship was $2,000.“Joshua has the heart of a servant leader. He leads by example and he's genuinely excited when good things happen for other people," Curry said. "He's an encouragement — he's good at building others up and does what he can to help encourage and motivate those around.8. What did Nelson's initial donation come from?A. His scholarship.B. His savings.C. His pocket money.D. His wages.9. What does the underlined phrase "having an open hand" in paragraph 2 mean?A. Ambitious.B. Courageous.C. Generous.D. Cautious.10. How did Curry feel when hearing Nelson's idea?A. Shocked.B. Confused.C. Excited.D. Delighted.11. What can be inferred about the Joshua Nelson Leaders In Action Scholarship fund?A. It never supports high school students.B. It was set up more than ten years ago.C. It was founded by Nelson and Curry.D. It is going very smoothly.DWhen an animal species is considered endangered, it means that the International Union for Conservation of Nature (IUCN) has evaluatedit as nearly extinct, which means that a majority of its population has already died off and the rate of birth is lower than the species’death rate. Today, more and more animal and plant species are on the way to extinction because of a variety of major factors that cause a species to become endangered, and as you might expect, humans play a role in quite a few of them — in fact, the biggest threat to endangered animals is human encroachment (侵入) on their habitats.Every species needs a habitat, where an animal finds food, raises its young. Unfortunately, humans destroy animal habitats in a number of different ways: building houses, clearing forests to getlumberand to plant crops, draining rivers to bring water to those crops, and making streets and parking lots.In addition, human development pollutes the environment with all kinds of chemicals, which destroys food sources and shelters for the creatures and plants of that area. As a result, some species die out while others are pushed into areas where they can’t find food and shelters — to make matters worse, when one animal population suffers, it affects many other species in its food web, so more than one species’population is likely to decrease.Habitat destruction is the number one reason for animal endangerment, which is why conservation groups work hard to repair the effects of human developments — many non-profit groups like the Nature Conservancy are taking measures to clean up coastlines and establish nature preserves to prevent further harm to native environments and species around the world.12. A species is considered endangered________.A. when the IUCN has noticed its population changeB. when most of its population has died offC. when the species’ birth rate is close to its death rateD. when the species is losing its habitat13. What does the underlined word “lumber” probably mean?A. Gas.B. Food.C. Chemicals.D. Wood.14. What is being done to protect the endangered species?A. Calling for human development.B. Raising money.C. Establishing nature preserves.D. Educating people.15. What is the main idea of the passage?A. Habitat destruction causes animal endangerment.B. Animals die out due to environment pollution.C. Measures need to be taken to increase species.D. Non-profit groups are making great contributions.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

（4 分）乐观不仅能使人感到年轻，美国的一项研究发现，乐观可能有助于提高人体抵抗疾病的免疫力。
研究人员先了解被调查者是否保持乐观情绪，然后再为其注射抗原。
被注射抗原后，其皮肤表面会因免疫系统产生而暂时出现一个肿块，肿块越大说明免疫系统的反应越强烈。
结果发现，越是乐观的被调查者，他们的免疫反应越强烈，越是悲观的被调查者，他们的免疫反应越弱。

权曰：“孤岂欲卿治经为博士邪！但当涉猎，见往事耳。
卿言多务，孰若孤？孤常读书，自以为大有所益。
”蒙乃始就学。
及鲁肃过寻阳，与蒙论议，大惊曰：“卿今者才略，非复吴下阿蒙！”蒙曰：“士别三日，即更刮目相待，大兄何见事之晚乎！”肃遂拜蒙母，结友而别。

②近日，故宫博物院的家具馆对外开放，许多参观者第一次欣赏到宫廷紫檀家具的绝美。
紫檀虽美，但它“五年一年轮，千年孕一木”，成材实属不易。
“十年树木，百年树人”，树木与树人往往类比，因为正像树木成材一样，年轻人成长也需要过程，只有经历了打磨和历练，才能积淀下精华。
③但反观当下，不少现象不免有些违反常识。
对“超速”的渴望正涌动成一股潮流。
“我报名了翻译速成班，一个月就能拿下口译资格证”“我加了个减肥群，10 天极速变苗条”“我刚买了明星快速养成手册，正在琢磨如何一夜成名”……急于工作，急于恋爱，急着看成效，似乎成为唯恐落后于时代节拍的“紧箍咒”。
④其实，“神速”未必变成“神话”，拼搏进取的姿态固然可取，但如果心浮气躁占了上风，就难免落入急于求成的窠臼。
⑤对“速度”的追求应鼓励，但对“速成”应怀有警惕之心。
事物发展自有其规律，人才成长也一样。
创业风口光景无限，但若缺乏优质产品，竞争过后只会留下一片狼藉；高薪职业令人羡慕，假如核心能力缺位，终非长久之策。
有人向往钢琴演奏的古典优雅，可练习枯燥，每个指法要经过千百次重复方能形成记忆；有人向往芭蕾舞者的风度翩翩，可完美舞姿的背后隐藏着练功中数不胜数的伤痛。
由此看来，所谓的“短期速成钢琴特长生”无非是商业招数，轻信这些并不会等来奇迹发生。
⑥速成背后，是偷懒投机心态在作祟。
从自身角度出发，心不能沉、气不能静，浮于表面不下苦功夫，想钻空子不坐“冷板凳”，都会导致自我管理缺失缺位，信心发生动摇。
现代社会选择自然是更多样了，实现选择的资源也更为丰富，从这个角度讲，所谓“速成”有一定市场。
但看树知人，但凡能速成的恐怕很难让你优势独具。
与其目光游移、辗转腾挪，倒不如一门深入、攀登高峰。
⑦“十年法则”认为，每个领域的大师都需要 10 年左右的勤学苦练；“一万小时定律”指出，从平凡到超凡的跨越，需要经历一万个小时的稳扎稳打。
著名小提琴家盛中国少年时被称为“天才琴童”，但“左手要长在琴上，右手的血脉要流入弓里”又需要怎样的艰苦付出？⑧器成还须久为功，卓越从来都不是速成的，持之以恒才是关键。
季羡林先生曾描述他在北大种莲的经历，几颗莲子经过两年扎根池底的力量积蓄，终于在第三年“长出了几个圆圆的绿叶”，并在第四年“蔓延得遮蔽了半个池塘”，绽放出“红艳耀目的荷花”。

（4 分）（四）（17分）同行的时光①旧历八月的北方小镇，碧空如洗，阳光柔软而熨帖——真是一年里最好的时光了。
斑驳的光影里，似乎所有的事物都在预谋着退场：道路两旁的树木现出憔悴的神色，高楼间隙里攀爬的丝瓜，只余下肥硕的一只，被大红的丝线缚在架子上。
②可是再好的时光里也会有人变老，我的外婆，她也一年一年老去了。
自理生活再不是一件简单的事情，所以早先几年，外婆就被姨妈接到城里去住了。
③听说我要回来，外婆早早地下楼，在路口处晒着太阳等我。
年近九十岁的她的确是苍老了，梳在耳后的头发从花白变成雪白，牙齿也几近掉光了，像是一件古旧的物件蜷．曲．在光影里。
④我很乐意加入他们晒太阳的队伍里。
到底有多久没有享受这样“负日之暄”的慵懒时光了，仿佛只有在这时候，晒太阳这件事情才会变得郑重起来，也只有此时，沉默才不是一种尴尬，而是变成一种专注。
⑤我不时地打量她，其实，她已有一些年老迟钝的征兆了，她有时会分不清楚自家的几个孩子。
她怔怔地看着我的外甥——那个百无聊赖的孩子，先是任性地到处扬沙，之后不知从哪里翻出来一把手斧，胡乱地砍来砍去。
我察觉到了她脸上现出的一种迷茫的神情——她心里已有些疑惑了。
⑥夕阳西下，时间在阳光和影子的胶着中缓缓而过。
⑦我扶她回家。
她对我说，她的母亲在临死的时候也没能喝上一口稀粥。
这让她每次吃饭的时候，都想落泪。
是啊，这些年里，你看她吃饭时的样子神色凝重，大概内心的纠结大过美食的享受吧。
⑧我陪她慢慢地挪步，如同小时候她扶我学步的样子。
傍晚的街道上，少有行人，世界有一种难得的安静，只愿我们的时光一直这样定格。
