云南省大理市下关第一中学2018-2019学年高一下学期英语期末考试试卷

阅读下面短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    Teenagers who talk on the phone a lot and hold their cell phones up to their right ears score worse on one type of memory test. That's the finding of a new study. That memory damage might be one side-effect of the radiation that phones use to keep us connected while we're on the go.

    Nearly 700 Swiss teens took part in a test of figural memory. This type helps us recall abstract symbols and shapes, explains Milena Foerster. She's an epidemiologist(流行病学家). She worked on the study as part of a team while Foerster was at the Swiss Tropical and Public Health Institute in Basel, Switzerland. Teens participated memory tests twjce, one year apart. Each time, they had one minute to memorize 13 pairs of abstract shapes. Then they were shown one item from each pair and asked to match it with one of five choices.

    The study volunteers also took a test of verbal memory. That's the ability to remember words. The two memory tests are parts of an intelligence test.

    The researchers also surveyed the teens on how they use mobile phones. And they got call records from phone companies. The researchers used those records to estimate how long the teens were using their phones. This allowed the researchers to calculate how big a radiation exposure each person could have gotten while talking.

    All cell phones give off energy in the form of radio frequency electromagnetic fields, or RF-EMFs. Radio and TV broadcasts also use this type of energy. So do microwave ovens and some other gadgets(配件).

    "For a phone, that energy carries information, in the form of calls or texts between phones and cell phone towers. That radiation also can travel into people's bodies as they use their phones. And some of its energy can be absorbed by the body. So far, scientists have not shown that radiation from phones causes harm," says the Federal

    Communications Commission. Research is ongoing, this agency notes.

(1)、What effects may the radiation have on teenagers?
A、It may be bad for their eye-sight. B、Their memory may be damaged. C、They may get lost while they are on the go. D、They may keep connected with some strangers.
(2)、How did the scientists draw a conclusion on the side-effect of the radiation?
A、By experiment. B、By logicality. C、By imagination. D、By reference.
(3)、What did the researchers want to know from phone companies?
A、What the teens concentrated on. B、Who the teens were connecting with. C, How C、much the teens were spending on phones. D、How much radiation exposure each person got.
(4)、What can we know from the words of the Federal Communications Commission?
A、It's unclear whether radiation from phones causes harm. B、People's bodies will absorb energy when they are calling. C、People's clothes can prevent the radiation harming their bodies. D、The radiation traveling into people's bodies does harm to their health.

    On Monday, the Centers for Disease Control and Prevention predicted that 42% of Americans could be overweight by 2030. Our expanding waistlines lead to not only a medical problem, but according to a recent article In The New York Times, it could also endanger personal safety in some situations—in an airplane crash, for example.

    The New York Times' Christen Negroni reports that engineers and scientists are questioning whether airplane seats are adequately constructed to protect overweight travelers. Government standards for airplane seat strength(强度)— first set moe than 60 years ago — require that the seats be made for a passenger weighing 170 pounds (77kg). Today, the average American man weighs nearly 194 pounds (88kg) and the average woman 165 pounds (75kg). Negroni reports:

    “If a heavier person completely fills seat, the seat is not likely to behave as intended during a crash,” said Robert Salazar, the leading scientist at the Center for Applied Biomechanics at the University of Virginia. “The energy absorption that is built into the aircraft seat is likely to be overpowered and the passengers will not be protected properly.”

    “Nor would the injury be limited to that passenger only,” Dr. Salzar said. “If a seat or a seat belt fails,” he said, “those people who are seated nearby could be endangered from 'the uncontrolled movements of the passenger'.”

    Most complaints about airplane seats focus on their lack of comfort and high ticket price, and whether overweight passengers should be made to buy two seats. But The New York Times' article brings up another reason to feel anxious about flying. Investigators of the issue got in touch with the airplane seat and seat belt makers, but they refused to comment on the problem. Experts agreed that crash testing should be done with overweight dummies (人体模型). Both airplane seats and seat belts should be tested, they said.

    Fortunately, however, according to Nora Marshall, a senior adviser at the National Transportation Safety Board, the board's investigators have never seen an accident involving a commercial plane in which the weight of a passenger was a problem.

    When you're on the go, your best friend and resource can be your phone. In the age of smart phones, apps are like guiding stars: They can point you in the right direction for a hotel, list expenses, send postcards, and much more. When used together, these apps can be the basic travel tool, placing a wealth of information at your fingertips no matter where you are on the planet. U.S. NewsTravel has picked the essential travel apps, known for their utility and reliability. Best of all, they cost absolutely nothing.

Trip It

    Your Personal Travel Agent

    Be your own travel agent and plan every detail of your trip—from car rental to accommodating restaurants—with Trip It. You can make travel schedule by hand, or simply forward the email confirmations of your flight, rental car, train tickets, and hotels to plans.

Weather Free

    Your Go-To Meteorologist(气象学者)

    Stop trying to explain the weather forecast on the evening news (particularly when it's in a foreign language). The Weather Free app informs you (in English) of the climate in various locations. It features the local weather, and other key factors that will inform your decision about what to wear before stepping outside.

Goby

    Your Event Guru

    When you're in a foreign city, you sometimes look around and ask: Where are all the people? Goby has the answer. This app pinpoints the neighborhood hot spots (including museums, hotels, eateries, and more) in your neighborhood. But its true value comes in finding nearby events. You'll discover concerts, plays, and more right around the corner.

    If you think you have two left feet but would love to be a good dancer then why not try your hand at dancing?

    That's exactly what I did five years ago and I immediately fell in love with dancing. To me, dancing is a magical experience: I've become fitter, look younger and feel more confident. I enjoy it so much that I will never give up this healthy pastime.

    It's very sociable as well. You meet people and make new friends while dancing the night away. Haven't you heard stories about how dancing inspired new romances or rekindled (重燃) old ones? My friends Joe and Rena just had their big day a few weeks ago after they met each other at a Ceroc workshop some three years before.

    The word “Ceroc” comes from the French language. Without the complicated footwork, it is easier to pick up by beginners. Another good thing about Ceroc is that while it is a partner dance, you don't have to bring a dancing partner.

    Other popular styles of dancing in the UK include ballroom, belly dancing, lindy hop, salsa, tango and tap dancing, just to name a few.

    No matter what types of dancing you do, one thing is for sure: you will become fitter. For office workers like me, dancing is good cardio exercise after a long day sitting in front of the computer screen. It also strengthens your muscles, improves your coordination(协调) and increases your physical confidence.

    Few people will end up being queens of the dance floor. The aim is not to win a competition but to enjoy the interaction(交流). As long as you do the right moves, keep the rhythm and most importantly keep an encouraging smile to your dancing partners, you will always be a winner!

 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。

It was a typical weekend for Mitch White and his friends. They were out celebrating a bachelor party, sailing the peaceful waters of the Minnesota River. They never expected that this single party would transform from a relaxed canoe trip into a painful rescue mission. With the sun setting, an unexpected bark changed everything.

Led by Mitch White, the soon-to-be-married man, they searched for the source of the sound along the banks of the river. Suddenly, a weak cry for help came from the mud. They were surprised to find that the head of a 13-year-old St. Bernard named Ed was barely visible in the thick mud. Mitch said, "The dog wasn't moving on its own, so we should feed it and give it water. " The dog looked like i had used all its strength.

The men took up their oars(桨) and began digging, their festive mood giving way to a focused rescue mission. It took them more than half an hour to free the trapped dog as it was already breathing very feebly after possibly being trapped for 24 hours. When they got the poor fellow out of the mud, he couldn't walk, so they carried him back to the house. Back home with his owner, George Niskanen, Ed began his slow restoration-a happy ending to a dangerous adventure. George was thankful to the bachelor party heroes.

Now, the people of Carver, Minnesota, have new heroes to cheer for. Indeed, this incredible act of bravery and compassion redefined the meaning of a bachelor party. It became a heroic tale of humanity, friendship, and the instinct(本能)to do what's right.

Hearing aids usually bring to mind images of ugly, ineffective devices mainly worn by the elderly. But this ill repute (恶名) is quickly changing, as they've recently taken a turn thanks to two innovators, Dr. Marco Vietor and Paul Crusius, who now lead the fastest-growing hearing aid company in the world-hear. com.

Hear. com's years of research led to the development of two game-changing hearing aids-the Silk and Styletto. These impressive devices pack cutting-edge (尖端的) technology in designs that are practically invisible. They also use a unique way that has been clinically (临床地) proven to deliver better-than-normal hearing so you can clearly understand speech in any environment. With additional features like Bluetooth and rechargeability, today's hearing aids are attracting even younger customers skilled in tech.

But hear. com knows it's not just about tech and design. They've put an enormous effort into the entire experience to make hearing care more accessible and more affordable. "Everyone should be able to hear well to live well," Crusius says. "And it's very individual. Each person's hearing loss is different and requires a personalized approach to find the best solution."

"We hear with our brains, not our ears. And it takes at least 30 days for our brain to adjust and relearn how to hear again with new hearing aids," Dr. Vietor says. "To guarantee your best outcome with hearing aids, we developed the industry's first 30-day program, Hearing Success Program, so customers have that extra level of care and knowledge to succeed."

And it's working. Hear. com has now helped more than 100,000 customers improve their hearing. Their A+ rating with the Better Business Bureau and 5-star rating on the customer review platform, Trustpilot, speaks for itself.

Hear. com's "customer first" approach also helps drive the company's success, encouraging employees to act like owners and put customers first. "We're investing heavily in shaping our company culture," Crusius says. "Individuals who work at hear. com say they are here to do more than a job. They're helping change lives all around the world."
