Answer the questions by marking the corresponding letter on Answer Sheet 2.Elite Math Competitions Struggle to Diversify Their Talent Pool [A]Interest in elite high school math competitions has grown in recent years, and in light of last summer's U.S. win at the International Math Olympiad—the first for an American team in more than two decades—the trend is likely to continue.　 [B]But will such contests, which are overwhelmingly dominated by Asian and white students from middle-class and affluent families, become any more diverse?Many social and cultural factors play roles in determining which promising students get on the path toward international math recognition. But efforts are in place to expose more black, Hispanic, and low-income students to advanced math, in the hope that the demographic pool of high-level contenders will eventually begin to shift and become less insular.　　[C]"The challenge is if certain types of people are doing something, it's difficult for other people to break into it," said Po-Shen Loh, the head coach of last year's winning U.S. Math Olympiad team and an associate professor of mathematics at Carnegie Mellon University. Participation grows through friends and networks and if "you realize that's how they're growing, you can start to take action" and bring in other students, he said.　　[D]Most of the training for advanced-math competitions happens outside the confines of the normal school day. Students attend after-school clubs, summer camps, online forums and classes, and university-based "math circles," or mathematician-led groups, to prepare for the paper-based and face-to-face competitions.　　[E]One of the largest feeders for high school math competitions—including those that eventually lead to the International Math Olympiad—is a middle school program called MathCounts. About 100,000 students around the country participate in the program's competition series, which culminates in a national game-show-style contest held each May. The most recent one took place last week in Washington. Students join a team through their schools, which provide a volunteer coach and pay a nominal fee to send students to regional and state competitions. The 224 students who make it to the national competition get an all-expenses-paid trip.　　[F] Nearly all members of last year's winning U.S. IMO team took part in MathCounts as middle school students—as did Loh, the coach. "Middle school is an important age because students have enough math capability to solve advanced problems, but they haven't really decided what they want to do with their lives," said Loh. "They often get hooked then."　　[G] Another influential feeder for advanced-math students is an online school called Art of Problem Solving, which began about 13 years ago and now has 15,000 users. Students use forums to chat, play games, and solve problems together at no cost, or they can pay a few hundred dollars to take courses with trained teachers. According to Richard Rusczyk, the company founder, the six U.S. team members who competed at the International Math Olympiad last year collectively took more than 40 courses on the site. Parents of advanced-math students and MathCounts coaches say the children are on the website constantly.　　[H] There are also dozens of summer camps—many attached to universities—that aim to prepare elite math students. Some are pricey—a three-week, intensive program can cost 4,500 or more—but most offer scholarships. The Math Olympiad Summer Training Program—the three-week math camp held by the Mathematical Association of America that leads straight to the international championship—is free for those who make it. Only about 50 students are invited based on their performance on written tests and at the USA Math Olympiad.　　[I] Students in university towns may also have access to another lever for involvement in accelerated math: math circles. In these groups, which came out of an Eastern European tradition of developing young talent, professors teach promising K-12 students advanced mathematics for several hours after school or on weekends. The Los Angeles Math Circle, held at the University of California, Los Angeles, began in 2007 with 20 students and now has more than 250. "These math circles cost nothing, or they're very cheap for students to get involved in, but you have to know about them," said Ruczyk. "Most people would love to get students from more underserved populations, they just can't get them in the door. Part of it is communication; part of it is transportation."　　[J] It's no secret in the advanced-math community that diversity is a problem. According to Mark Saul, the director of competitions for the Mathematical Association of America, not a single African-American or Hispanic student—and only a handful of girls—has ever made it to the Math Olympiad team in its 50 years of existence.Many schools simply don't prioritize academic competitions. "Do you know who we have to beat?" asked Saul. "The football team, the basketball team—that's our competition for resources, student time, attention, school dollars, parent efforts, school enthusiasm."　　[K] Teachers in low-income urban and rural areas with no history of participating in math competitions may not know about advanced-math opportunities like MathCounts—and those who do may not have support or feel trained to lead them.　　[L] But there are initiatives in place to try to get more underrepresented students involved in accelerated math. A New York City-based nonprofit called Bridge to Enter Mathematics runs a residential summer program aimed at getting underserved, mostly black and Hispanic students working toward math and science careers. The summer after 7th grade, students spend three weeks on a college campus studying advanced math for seven hours a day. Over the next five years, the group helps the students get into other elite summer math programs, high-performing high schools, and eventually college. About 250 students so far have gone through the program, which receives funding from the Jack Kent Cooke Foundation.　　[M] "If you look at a lot of low-income communities in the United States, there are programs that are serving them, but they're primarily centered around, 'Let's get these kids' grades up,' and not around, 'Let's get these kids access to the same kinds of opportunities as more-affluent kids,' " said Daniel Zaharopol, the founder and executive director of the program. "We're trying to create that pathway."Students apply to the program directly through their schools. "We want to reach parents who are not plugged into the system," said Zaharopol.　　[N] In the past few years, MathCounts added two new middle school programs to try to diversify its participant pool—National Math Club and the Math Video Challenge. Schools or teachers who sign up for the National Math Club receive a kit full of activities and resources, but there's no special teacher training and no competition attached.　　[O] The Math Video Challenge is a competition, but a collaborative one. Teams of four students make a video illustrating a math problem and its real-world application. After the high-pressure Countdown round at this year's national MathCounts competition, in which the top 12 students went head to head solving complex problems in rapid fire, the finalists for the Math Video Challenge took the stage to show their videos. The demographics of that group looked quite different from those in the competition round—of the 16 video finalists, 13 were girls and eight were African-American students. The video challenge does not put individual students on the hot seat—so it's less intimidating by design. It also adds the element of artistic creativity to attract a new pool of students who may not see themselves as "math people."Section BElite Math Competitions Struggle to Diversify Their Talent Pool1.

Part 2: 根据中文释义，选择两个选项，组合成正确的单词_ _流言蜚语；闲言碎语；传闻sap sipgas sepgus gos

The AlphaGo program's victory is an example of how smart computers have become． But can artificial intelligence （AI） machines act ethically， meaning can they be honest and fair？ One example of AI is driverless cars． They are already on California roads， so it is not too soon to ask whether we can program a machine to act ethically． As driverless cars improve， they will save lives． They will make fewer mistakes than human drivers do． Sometimes， however， they will face a choice between lives． Should the cars be programmed to avoid hitting a child running across the road， even if that will put their passengers at risk？ What about making a sudden turn to avoid a dog？ What if the only risk is damage to the car itself， not to the passengers？ Perhaps there will be lessons to learn from driverless cars， but they are not super-intelligent beings． Teaching ethics to a machine even more intelligent than we are will be the bigger challenge． About the same time as AlphaGo's triumph， Microsoft's 'chatbot' took a bad turn． The software， named Taylor， was designed to answer messages from people aged 18-24． Taylor was supposed to be able to learn from the messages she received． She was designed to slowly improve her ability to handle conversations， but some people were teaching Taylor racist ideas． When she started saying nice things about Hitler，Microsoft turned her off and deleted her ugliest messages． AlphaGo's victory and Taylor's defeat happened at about the same time． This should be a warning to us． It is one thing to use AI within a game with clear rules and clear goals． It is something very different to use AI in the real world． The unpredictability of the real world may bring to the surface a troubling software problem． Eric Schmidt is one of the bosses of Google， which own AlphaGo． He thinks AI will be positive for humans． He said people will be the winner， whatever the outcome． Advances in AI will make human beings smarter， more able and "just better human beings．"（1）What does the author want to show with the example of AlphaGo's victory？ ____ A． Computers will prevail（战胜） over human beings．B． Computers have unmatched potential．C． Computers are man's potential rivals．D． Computers can become highly intelligent．（2）What does the author mean by AI machines acting ethically？ ____ A． They are capable of predicting possible risks．B． They weigh the gains and losses before reaching a decision．C． They make sensible decisions when facing moral dilemmas．D． They sacrifice everything to save human lives．（3）What is said to be the bigger challenge facing humans in the AI age？ ____ A． How to make super-intelligent AI machines share human feelings．B． How to ensure that super-intelligent AI machines act ethically．C． How to prevent AI machines doing harm to humans．D． How to avoid being over-dependent on AI machines．（4）What do we learn about Microsoft's 'chatbot' Taylor？ ____ A． She could not distinguish good from bad．B． She could turn herself off when necessary．C． She was not made to handle novel situations．D． She was good at performing routine tasks．（5）What does Eric Schmidt think of artificial intelligence？ ____ A． It will be far superior to human beings．B． It will keep improving as time goes by．C． It will prove to be valuable to human beings．D． It will be here to stay whatever the outcome．

I come from Kitengela, a farming community on the edge(边缘) of Nairobi National Park of Kenya(肯尼亚). Since the age of nine. I have helped to look after my family’s cows. As a child, in my free time. I enjoyed playing with electronics. I made my own inventions, such as electronic toys from car parts and other things. I also built other electronic devices(仪器) for my neighbors.At the age of 13, I invented something that changed my life. It also changed the lives of many people in my community. One night, a lion from the park came into my family’s farm and killed one of our cows. I was angry. However, killing the lion, I thought, was not the best way to solve the problem. Instead, I decided to invent a solutionThe first idea I got was to use fire, because I thought lions were scared of fire. But I came to realize that that didn’t really help, because it was even helping the lions to see through the cowshed (牛棚). So I didn’t give up. I continued.And a second idea I got was to use a scarecrow(4稻草人). I was trying to trick the lions into thinking) that I was standing near the cowshed. But lions are very clever. They will come the first day and they see the scarecrow, and they go back. But the second day, they’ll come and they say,this thing is not moving here, it is always here! So he jumps in and kills the animals.So one night, I was walking around the cowshed with a torch(手电筒), and that day the lions didn’t come. And I discovered that lions were afraid of a moving light. So I had an idea.64. What was Turere interested in when he was a child?A. Tricking the neighbors. B. Looking after cows.C. Playing with electronics. D. Making car parts65. What does the underlined word “it” in Paragraph 4 refer to?A. The lion. B. The scarcer.C. The cow. D. The cowshed66. What’s the solution to driving the lion away?A. Using a moving light. B. Using a torch.C. Using a scarecrow. D. Using fire.67. What can we get from the passage?A. The lion killed all the cows. B. Turere killed the lion at last.C The lion no longer lived in the park. D. Turere’s invention made peace with lions.CPlaying video games and getting money for it seems like a dream job for many of today’s teenagers. But is it all fun and games?Big businessPro (professional) gaming is certainly big business. In 2017, there were more than 3,000 gaming competitions and over 10,000 professional players worldwide. A large number of people watch their competitions online, and successful gamers can get more than 1,000,000 dollars from prize money and ads. The industry is clearly thriving.What it takesBecoming a professional is not just about being good at playing games- it also takes a lot of hard work. Some pro gamers practice for fourteen hours a day. "You need to spend much time and put all your efforts to it", says ex-gamer GeorgeNot all fun and gamesIt can be a difficult job as well. Stress is a big problem for gamers. Tiredness is another, and injuries(受伤) are common. Top player Hai Lam had wrist(手腕) problems after years of pro gaming. Careers(生涯)are short, and many gamers retire (退休) before they are 30 and try to find another job.However, the bad points probably won’t change the dreams of many teenage gamers. And angry parents are still likely to hear the excuse, “But I’m just practicing for my future job!”68. How many professional players were there around the world in 2017?A. 130.000. B. More than 3, 000.C. Over1,000,000. D. More than 10.00069. What does the underlined word "thriving" in Paragraph 2 meanA. Getting worse. B. Doing well. C. Developing slowly. D. Changing quickly.70. What can we infer from the last sentence of the passage?A. Children are angry with their parentsB. Teenagers practice games for their future jobsC. Some teenagers are crazy about playing gamesD. Parents stop their children playing games successfully.71. What’s the main idea of the passage?A. Pro gaming isn’t all fun and gamesB. The career as a pro gamer doesn’t last longC. Being a pro gamer is a good choice for teenagers.D. Being a pro gamer is an easy way to make money.DEveryone faces challenges in their life, but some are more important than others. Daniel Kish had serious problems with his eyes when he was born. And doctors took away both of his eyes before he was fourteen months old.Soon after, however, he started to do an amazing thing. He started to make clicking(咔塔) sounds with his tongue舌头) to help him move around. Much like a bat(蝙幅), he now moves about using sonar(声呐). He is so good at it that he can ride a bicycle in traffic. He and his group, World Access for the Blind, teach others how to use sonar. In this interview with National Geographic, Kish explains how the process works.How does sonar work?“When I make a clicking sound, it makes sound waves. These waves reflect(反射) off surfaces all around and return to my ears. My brain then processes the sounds into images(图像). It’s like having a conversation with the environmentWhen you click, what do you see in your mind?"Each click is like a camera flash. I make a 3D image of the things around me for hundreds of feet in every directionWhat is it like riding a bike using sonar?“It’s exciting and enjoyable but requires a lot of focus. I click up to two times per second,, much more than I usually do.”Is it dangerous to move around the world in this way?"Much of the world lives in fear of things that we mostly imagine. I have a habit of climbing anything and everything, but I never broke a bone (骨头) as a kid.”How challenging is it to teach people to use sonar?“Many students are surprised how quickly results come. Seeing isn’t in the eyes, it’ s in the mind.”72. What’s the main idea of Paragraph 2?A. Kish explains how sonar works.B. Kish teaches people how to use sonar.C.

They are very necessary for our health and help our bodies work well. They can help reduce (减少) the risk of getting ill. There are a lot of vegetables and fruit to choose from and they taste delicious. 76It’s easy to buy our food from the local supermarket, so why do we go to the trouble of growing our own? Here are several good reasons:77 You can pick and eat it at once. When you have tried it, you will agree that vegetables and fruit that are eaten straight from the garden taste better than anything you can buy in a supermarket.You may want to cut down on your "food miles"-the distance that a product has travelled before it reaches your kitchen. Many food packages are flown halfway across the earth. 78Homegrown food is likely to be healthier. Food producers often use fertilizers(化肥) and pesticides (农药) which can end up in your food. If you grow your own, things are different. 79 You might also choose to grow some traditional vegetables and fruit. These often have more of the vitamins, minerals(矿物质) and protein(蛋白质) that keep you healthy.80 And you can grow your own even if you only have a small backyard or a balcony(R E). Some food can grow well in pots, including lettuce, tomatoes, potatoes and carrots. You can recycle plastic bottles and cups to grow something. Just make sure there are holes for drainage (排水) and a small plate under them to catch drops of water.Happy gardening!A. Best of all, you can grow your own! B. But where to grow your own is a problem. C. That’s not so good for you, or for the planet. D. Food that you grow yourself is always fresh. E. If you have a large garden, growing your own is easy. F. You can control what goes on and into the food you eat. G. So it’s better to eat more vegetables and fruit in our daily life. .
