  Regardless of the weather or the distance, Paul Wilson will make sure low-income students in his neighbourhood arrive at their college classes on time.

  A retired enginner, 76-year-old Wilson has been _1_ free rides to college students for the past eight years. Since he first started _2_ his car to the young people, Wilson has _3_ an astonishing 64,000 miles, and has had countless pleasant and often humorous _4_ with the students he transports to and from school. The students who he's _5_ have gone on to become physicians, teachers and ngineers, but what they've also got out of their time in school is finding a role model and a friend in Wilson. Some students _6_ call him "Grandpa".

  Tina Stern _7_ rides from Wilson for all her four years in college, and the trips meant much more to her than just free _8_ . "It's not just a ride; you're not just sitting there in _9_ silence or with your headphones on," Stern said. "He asks you questions and actually _10_ the answers, so the next time you ride with him, he'll _11_ those things."

   Wilson first worked as a driver through a student-support programme of the non-profit organisation, On Point for College. Although the _12_ asks the members only to drive students to and from their classes, Wilson often goes _13_ to ensure the welfare and safety of the students. If they have problems with registration, Wilson is there to _14_ them. If they run out of certain daily necessities, Wilson will drive to the nearest store and purchase what's needed. If a student gets hungry on the long drives to and from school, Wilson never _15_ to buy them a meal.

   For many students, Wilson's help is not only appreciated, it's also entirely _16_ for them to be able to complete their college education. Some students don't have a reliable car, while others have to _17_ vehicles with parents who work six days a week. For them, riding with Wilson has _18_ them to complete their education — but according to Wilson, he benefits just as much from the _19_ . "I just love driving, and I love these kids," Wilson said. "It's such a(n) _20_ to be a part of these kids' lives, even just for a few hours, geting to know them and hearing their stories."

  Alice Moore is a teenager entrepreneur (创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids' teeth, instead of destroying them.

  It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, "Why can't I make a healthy candy that's good for my teeth so that my parents can't say no to it?" With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.

  With her dad's permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.

  Moore then used her savings to get her business off the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore's product - CanCandy.

  As CanCandy's success grows, so does Moore's credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she's also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.

  Meanwhile, with her parents help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn't driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilieCandy's profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.

  The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams(欺诈). We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it's too little, too late. By the time these "solutions" (解决方案) become widely available, scammers will have moved onto cleverer means. In the near future, it's not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.

  That's because there are a number of powerful voice manipulation (处理) and automation technologies that are about to become widely available for anyone to use. At this year's I/O Conference, a company showed a new voice technology able to produce such a convincing human-sounding volce that it was able to speak to a receptionist and book a reservation without detection.

  These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision. A decade of data breaches (数据侵人) of personal information has led to a situation where scammers can easily learn your mother's name,and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, tricking you into “confirming" your address, mother's name, and card number. Scammers follow money,so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.

  We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications - using apps like FaceTime or WhatsApp, which can be tied to your identity.

  Credibility is hard to earn but easy to lose, and the problem is only going to get harder from here on out.

  By the end of the century, if not sooner, the world's oceans will be bluer and greener thanks to a warming climate , according to a new study.

  At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) саllеd рhуtорlаnktоn. Весаuѕе оf thе wау lіght rеflесtѕ оff thе organisms , these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean's appearance.

  Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean's warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.

  Stephanie Dutkiewicz, a scientist in MIT's Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. "Not only are the quantities of phytoplankton in the ocean changing," she said, " but the type of phytoplankton is changing."

  And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said,"it will change the type of fish that will be able to survive." Those kinds of changes could affect the food chain.

  Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. "It'll be a while before we can statistically show that the changes are happening because of climate change," Dutkiewicz said, "but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet. "

三. 选句填空(共 1 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。选项中有两项为多余选项。

  Much of the work in today's world is accomplished (完成) in teams. Most people believe the best way to build a great team is to gather a group of the most talented individuals. _36_ Companies spend millions hiring top business people. Is their money well spent?

  _37_ They focused on football, basketball and baseball. The results are mixed. For football and basketball, adding talented players to a team proves a good method, but only up to the point where 70% of the players are top talent; above that level, the team's performance begins to decline. Interestingly, this trend isn't evident in baseball, where additional individual talent keeps improving the team's performance.

  To explain this phenomenon, the researchers explored the degree to which a good performance by a team requires its members to coordinate (协调) their actions. _38_ In baseball, the performance of individual players is less dependent on teammates. They conclude that when task interdependence is high, team performance will suffer when there is too much talent, while individual talent will have positive effects on team performance when task interdependence is lower. If a basketball star is, forexample, trying to gain a high personal point total, he may take a shot himself when it would be better to pass the ball to a teammate, affecting the team's performance. Young children learning to play team sports are often told, "There is no I in TEAM." _39_

  Another possibility is that when there is a lot of talent on a team, some players may make less effort. Just as in a game of tug-of-war (拔河比赛) whenever a person is added, everyone else pulls the rope with less force.

  _40_ An A-team may require a balance - not just A players, but a few generous B players as well.

  • A. It's not a simple matter to determine the nature of talent.
  • B. Sports team owners spend millions of dollars attracting top talent.
  • C. The group interaction and its effect drew the researchers' attention.
  • D. Stars apparently do not follow this basic principle of sportsmanship.
  • E. Several recent studies examined the role of talent in the sports world.
  • F. Building up a dream team is more complex than simply hiring the best talent.
  • G. This task interdependence distinguishes baseball from football and basketball.
