AAn Oceans VacuumThere’s a collection of plastic trash in the middle of the Pacific Ocean. It’s bigger than Texas-and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes 62-mile-long floating barriers that would use natural currents to trap trash. If next year’s trials succeed, a full cleanup operation would aim to start in 2020. It could reduce the trash by 42% over 10 years.Easy-On ShoesIn 2012, Mathew Walzer, a high school student with a disability, sent a note to Nike. “My dream is o go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.”Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase. The basketball shoe can be fastened with one hand. A pair of Nike FlyEase shoes sells for $130.An Airport for Drones(无人机)As Amazon, Google, and others get ready for drone delivery service, there is one big question: what kinds of home bases will their drones have? Rwanda, in Africa, may have the answer. There, workers will soon start work on three “drone ports”. The goal is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside. Construction is set to be completed in 2020.21.What’s the advantage of the Oceans Vacuum?A. It can be a money-saverB. It can grow year by yearC. It can tear plastic into piecesD.

Not far away, a three-story house attracted my eyes.It was nothing like the one I lived in with my mother, a small dark place with rules about befriending others. “Don’t. Never, ever talk to anyone,” my mother said.One day, in sixth grade, a black-haired woman was introduced to our class: Mrs. Reese. Reese explained that she was starting Spanish Club. She invited anyone interested in learning Spanish language and culture to stay after school.I could not take my eyes off her bracelets(手镯) and shining rings. The bell rang, and to my shock, no one went up to Mrs. Reese. I was under strict orders to go straight home. But that day, I stayed. I asked Mrs. Reese when the club started.“We could begin right now if you like,”she said with a smile. I felt beautiful. That day I learned that the house of my dreams was her house. I learned how to answer questions about my age and my favorite food in Spanish. And I learned, Do you want to come over tomorrow for cooking lessons?I wanted to say “Yes”, but Mom’s words held me back.I begged my mother all summer and into fall, well after Spanish Club had dissolved. I wept at night sometimes, so worried that Mrs. Reese and her family would move away.At some point, I managed to wear my mother down and one Saturday afternoon. I rode out to Mrs. Reese’s house.The details of that afternoon are marked in my mind: We had tea. She painted my toenails red. We made a garlicky picadillo. We spoke in Spanish. In Spanish, my voice was loud and romantic. This is the real me! I remember thinking.My mother never permitted me another visit to Mrs. Reese’s house. But four decades later, I still remember that day and the life she showed me, proof of a possible future.24.What kind of family was the author from?A. Hard-upB. Two-parentC. Stress-freeD.

The beauty of SpanishB. The wonder of a new worldC. The power of self-confidenceD. The importance of independenceCEnglish is full of colorful phrases to describe shyness. Someone shy might be called shrinking violet or a wallflower, while for especially nervous types we have the curious expression: they wouldn’t say boo to a goose.None of these are traditionally seen as positive descriptions, even if you like geese. In a culture of go-getting, high achievers, shy people don’t come first.Or that's what the self-help industry would have you believe. Bookshops are filled with vital tomes(巨著) that promise to help beat social fears and find success in life, love and business. That is why one book, Shrinking Violets: A Field Guide to Shyness, bucks the trend. It became a sudden success across English-language media recently for its new take-on shyness.Author Joe Moran says that despite struggling with shyness and longing for loneliness all his life, being shy can also be "a gift". Freed from the constant urge to participate and compete in social situations, people are liberated to look at the world in new ways, and gain fresh insights.Indeed, many of the world's great thinkers and artists are introverts(内向的人). Scientists Charles Darwin and Albert Einstein preferred their own company; actress Keira Knightley often finds herself tongue-tied at parties; and Harry Potter author JK Rowling claims she used to be too nervous to even borrow a pen.Moran told BBC Future: "I think shyness probably does turn you into an amateur anthropologist(人类学家), really-you are more likely to be an observer."So, while extroverts make all the noise, they don't necessarily have the best ideas.If you're shy, you've probably known this for a long time. You just don't shout about it.28.When someone is being called a wallflower, he is being .A. praised for his graceB. admired for his characterC. laughed at for his shynessD. told off for his nervousness29.The underlined phrase “bucks the trend” in Paragraph 2 probably means ””.A. going against the trend and succeedsB. changing the public idea completelyC. becoming unpopular and unacceptedD. becoming the major concern of people30.The author mentioned many famous shy people in order to .A. point out the harm shyness bringsB. disconnect shyness and successC. shows the reasons for shynessD. prove shyness contributes to science31.What is the author’s attitude towards shyness?A. OpposedB. IndifferentC. SupportiveD. CriticalDFrigatebirds seagoing fliers with a 6-foot wingspan, can stay aloft(up in the air) for weeks at a time, a new study has found.Since the frigatebird spends most of its life at sea, its habits outside of when it reproduces on land aren’t well-known-until researchers started tracking them around the Indian Ocean. What the researchers discovered is that the bird’s flying ability is unbelievable.Ornithologist(鸟类学家) Henri Weimerskirch put satellite tage(标签) on a couple of dozen frigatebirds. When the data started to come in, he could hardly believe how high the birds flew."First, we found, 'Whoa, 1,500 meters. Excellent,' " says Weimerskirch, "And after 2,000, after 3,000, after 4,000 meters-OK, at this altitude they are in freezing conditions, especially surprising for a tropical bird.""There is no other bird flying so high relative to the sea surface," he says. "It's the only bird that is known to intentionally enter into a cloud," Weimerskirch says. And not just any cloud-a soft, white cumulus cloud(积云). Over the ocean, these clouds tend to form in places where warm air rises from the sea surface. The birds take a ride on the current of rising air, all the way up to the top of the cloud.Frigatebirds have to find ways to stay aloft because they can't land on the water. Since their feathers aren't waterproof, the birds would drown in short order. They feed by harassing other birds in flight until they bring whatever fish they've swallowed back into their mouth and the frigatebird takes it.So in between meals, frigatebirds fly higher... and higher.In one case, for two months-continuously aloft.One of the tagged birds flew 40 miles without a wing-flap. Several covered more than 300 miles a day on average, and flew continuously for weeks. They are blessed with an unusual body. No bird has a larger wing surface area compared with body weight.32.How did researchers feel when data about frigatebirds reached them?A. CalmB. SurprisedC. HopefulD. Anxious33.According to the text, how can frigatebirds fly so high?A. By flying into a cloudB. With the help of researchersC. Thanks to advanced technologyD. By following other birds into the sky34.What does the underlined word ”they” in the text refer to?A. FrigatebirdsB. Other birdsC. Small fishD. Larger fish35.In what aspect are frigatebirds different from other birds?A. When they give birthB. What they feed onC. Their body weightD. Their wing surface area第二节（共5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。
