1 . The world’s coral reefs do more for the planet than provide underwater beauty. They protect shorelines from the effects of hurricanes. An estimated 500 million people earn their livelihood from the fishing stocks and tourism opportunities reefs provide. The tiny animals that give rise to reefs are even offering hope for new drugs to treat cancer and other diseases.
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. So now scientists around the world are looking for all kinds of ways to protect and maybe even revive(复苏) corals. In the Bahamas, Ross Cunning, a research biologist at Chicago’s Shedd Aquarium, is focusing on corals with genes that could make them natural candidates for restoration projects. He recently published a study of two Bahamian reefs, one that seemed to survive an intense 2015 heat wave, and one that didn’t.“It sets the stage to find out which genes are responsible for thermal tolerance,” says Cunning, adding that he hopes discovering those genes will help scientists one day breed more heat-tolerant coral.
In Massachusetts, Cohen’s research has found two key elements that seem to protect corals. The first: internal(内部的) waves beneath the ocean’s surface that bring cooler currents to heat-struck corals, essentially air-conditioning them as temperatures rise. The second: adaptation, a quality that corals found in Palau’s warm lagoons(环礁湖) seem to display.On average, these lagoons submerge(淹没) coral in water that is two degrees Celsius warmer than the water outside the lagoons. “We think the fact that they can deal with these higher temperatures is built into their genetics and allows them to deal with the heat waves.”
She’s also found evidence of corals evolving more quickly in the past two decades to withstand rapidly warming temperatures. The big question scientists are now enquiring into, says Cohen, is whether there’s a cap on how much more heat corals can adapt to. Cohen calls these regions with heat-adapted corals as “super reefs,” and like Friendlander, advocates for using marine reserves to protect them.

2 . Art and science may seem like opposite things. One means the creative flow of ideas, and the other means cold, hard data-some people believe. In fact, the two have much in common. Now, a study finds art can help students remember better what they have learned in the science class.
Mariale Hardiman, an education specialist at Johns Hopkins University, noticed that students who used art in the classroom listened more carefully. They might ask more questions. They might volunteer more ideas. What’s more, students seemed to remember more of what they had been taught when their science lessons had involved(涉及) art. To prove that, Hardiman teamed up with some researchers and six local schools.
In the experiment, the researchers worked with teachers in 16 fifth-grade classrooms. They provided traditional science lessons and art-focused ones. In a traditional science class, for example, students might read aloud from a book. In the art-focused one, they might sing the information instead.
The team randomly assigned(随机分配) each of the 350 students to either a traditional science classroom or an art-focused one. Students then learned science using that way for the whole unit-about three weeks. When they changed to a new topic, they also changed to the other type of class. This way, each student had both an art-focused class and a traditional one. Every unit was taught in both ways, to different groups of students. This enabled the researchers to see how students did in both types of classes.
The team found that students who started off in a traditional class performed better after they moved into an art-focused class. But those who started off in an art-focused class did well even when they went back to a traditional science class. These students appeared to use some of the art techniques(技巧) after going back to a traditional class. Classroom teachers reported that many students continued to sing the songs that they learned after finishing the unit. “The more we hear something, the more we retain it,” Hardiman says. “It suggests that the arts may help students apply creative ways of learning on their own.”

3 . You know that classics like Little Women and To Kill a Mockingbird started as novels. But you probably didn’t know that these other famous movies also came from books.
Hidden Figures
This film told the story of real-life Katherine Johnson and other female African-American mathematicians who helped drive the United States into space in the 1960s. It was actually based on a 2016 non-fiction book and the movie did boost sales of the book.
Forrest Gump
The 1994 movie which was based on the book by Winston Groom won six Academy Awards, including Best Picture and Best Actor for the star Tom Hanks. Although the movie’s critical and box-office success gave the book a huge boost, it’s the film that made its mark on pop culture history.
The Girl on the Train
Paula Hawkin’s psychological thriller, about a woman on a train who thinks she sees something strange out of the window, was a huge success. But unlike the fast—paced, can’t-be-put-down quality of the novel, the movie was boring.
Field of Dreams
It’s hard to describe the plot of this movie: Ray Kinsella hears a voice telling him to build a baseball field in his Iowa cornfield, and what happens next explores the themes of lost dreams, childhood heroes, and healing the pain of the past. The 1989 movie is based on W. P. Kinsella’s 1982 original, Shoeless Joe, but cuts out some extra characters.
1. Which is the best choice for a person who loves math?| A．Hidden Figures. | B．Forrest Gump. |

| A．Tom Hanks. | B．Winston Groom. |
| C．Paula Hawkin. | D．W. P. Kinsella. |
| A．It is a romantic comedy. | B．It presents several themes. |

4 . By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friend’s new baby on Facebook, or reading about Justin Bieber’s latest conflict with the law on Twitter, what are some of the real influences?
Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choices. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills.
Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker.
Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work. In fact, studies show that British companies have lost billions of dollars per year in productivity because of social media addiction among employees.
Also, what you carelessly post on the Internet can come back to trouble you. Revealing (泄露) personal information on social sites can make users vulnerable (易受伤害的) to crimes like identity theft, stalking, etc. Many companies perform a background check on the Internet before hiring an employee. If a potential employee has posted something embarrassing on social media, it can greatly affect their chances of getting the job. The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks.
Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.
1. Paragraph 2 mainly shows that social networks ________.| A．help students finish their homework | B．offer professionals good chances |

6 . Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published on Wednesday in the journal Neurology suggests.
Researchers from the University of Leipzig in Germany gathered more than 1,000 retired workers who were over age 75 and assessed the volunteers’ memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to come back to the lab every 18 months to take the same tests.
Those who had held mentally stimulating, demanding jobs before retirement tended to do the best in the tests. And they tended to lose cognitive (认知的) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants’ overall health status.
“This works just like physical exercise,” says Francisca, who led the study. “After a long run, you may feel like you’re in pain and tired. But it makes you fit. After a long day at work — sure, you will feel tired, but it can help your brain stay healthy.
It’s not just corporate jobs, or even paid work that can help keep your brain fit. Francisca points out. A waiter’s job, for example, that requires multitasking, teamwork and decision making could be just as stimulating as any high-level office work. “Running a family household also requires high-level planning and coordinating abilities,” she says. “You have to bring order to the activities of the children and take care of the bills and groceries.”
Of course, our brains can decline as we grow older for lots of reasons — including other environmental influences or genetic factors. Sill, continuing to challenge yourself mentally and keeping your mind busy can help.

8 . On a tram smoothly pulling into the heart of Luxembourg City, Marck gives a smile and takes a look at the fabric of the seat next to him. For him, the city’s trams are more than just transport. More even than the focus of his job. They are about transforming his country and, perhaps, changing the world.
Marck is the director general of Luxtram, Luxembourg’s modern trams. It first started running services two years ago. Next year, Luxembourg will become the world’s only country to get rid of fares on all its forms of public transport. Luxembourg’s traffic problems come from its army of workers. The population of the capital city almost doubles during the working day, when more than 110,000 people travel in and out.
After three decades when its roads have become so crowded, Luxembourg is going to do something remarkable. Free fares, and a plan to persuade people to switch from cars to trams or trains. Marck, along with many others, is excited to see what happens next. “The fact that this is free means that everyone can use it — young or old, rich or poor,” he said. “Everyone can say to themselves it’s better to leave the car at home. We must continue to improve and extend the network. It must always be comfortable, well-connected, efficient.”
Lydie Polfer, the city’s mayor, says she hopes to reach the point where more than a third of people come into the city using public transport — at the moment, it’s less than one in five. She said, “It’s not practical to ban cars because some people, like the elderly, need them. But everyone has to be aware that he or she can do something to improve the situation. There is an expression in German — you are not in the traffic jam — you are the traffic jam, and that is true. I think that making it free will be the biggest arguments for people to use public transport. ”
1. Why does Marck think the city’s trams are more than just transport?| A．The trams are his goal that he strives for. |
| B．There are more means of transportation than trams. |
| C．City’s trams bring more changes beyond transport. |
| D．The trams are the heart of Luxembourg City transport system. |
| A．The cause of the traffic problems. | B．The means of public transport. |
| C．The development of running services. | D．The increase of working population. |
| A．The convenience. | B．The fare. | C．The comfort. | D．The efficiency. |
| A．The elderly needn’t use public transport. |
| B．It’s possible to persuade most people to use the trams. |
| C．Everyone can do his part to improve transport situation. |
| D．Those who don’t take public transport cause traffic jams. |
9 . Cimabue, the greatest painter of a Middle Ages in Italy, was surprised one day after his lunch break to discover that a fly had seated itself under the nose of a character that he had been working on. He swatted (重拍) at the fly, but it did not move. He reached out to touch the insect, only to find it was only wet paint. Turning around, he saw that his apprentice (学徒), Giotto, was laughing. Giotto had painted the fly when Cimabue was away, and it looked so real that Cimabue had been completely fooled.
Giotto di Bondone was born into a poor family in a village. Legend has it that one day, when Cimabue was wandering around the countryside, he spotted a young shepherd boy drawing pictures of his sheep, which were so vivid that Cimabue immediately asked him to come to Florence and learn how to paint. That was how Giotto’s story began in Florence, where the young student flourished under Cimabue s instruction and soon surpassed his master in skill.
At that time, people in paintings didn’t look real, and the symbolism of art was difficult for viewers to connect with it. Innovation (创新) was not stressed, so art had remained the same for hundreds of years.
However, Giotto thought art should be something more connected with people in a more realistic way. His masterpieces included the forty major frescoes (壁画) for the Arena Chapel. Adopting many techniques that were uncommon then, he painted people the way he saw them, instead of the overly tall and boxy people that other artists painted. He created three-dimensional space by using perspective, something that had not been done since Roman times.
In addition to painting, Giotto wrote poetry and drew architectural plans. When Giotto was in his sixties, he painted the Ognissanti Madomma, another famous work of art. He continued working until the age of seventy. The ideas Giotto brought to painting throughout his life revolutionized the art world and made him one of the greatest painters ever.

| A．Great minds think alike | B．Innovation is the vitality of art |
| C．Constant dripping wears away a stone | D．A slow sparrow should make an early start |
10 . For Sandra, the teachers who stuck in her mind were the ones that gave her their time and effort and really prepared her for her future.
She saw herself as a teacher who helped students and gave them love for what they had to do, whether they wanted to do it or not.
Giving students that push to get better grade made a great difference to them. When they got it, the result was just amazing.”
Based on this teaching concept, Sandra focused on making each student a better “himself”. And what’s more, she has been among one of her former teachers and really has given something back. She once received a huge bunch of flowers with a card in it, writing, “Dear Sandra, you’ve given me the time and energy to help me get what I needed.
| A．She kept encouraging her students |
| B．It is useful to make friends with students |
| C．Her encouragement turned out to be of great use |
| D．It makes you feel like you’ve done your job so well |
| E．It is you and your teaching style that make it possible |
| F．So she chose to train as a teacher after college graduation |
| G．Looking back, there were many moments to make her proud |
