广东省汕头市潮阳实验学校2016-2017学年高二下学期英语第一次3月月考试卷

根据短文内容的理解,选择正确答案。
      Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
"To provide enough power, we need certain methods with high energy density(密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU. "The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."
      Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
      "People hear the word ‘nuclear' and think of something very dangerous," he said, "However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems."
      His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.
"The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor," Kwon said, "By using a liquid semiconductor, we believe we can minimize that problem."
      Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
(1)、Which of the following is true of Jae Kwon?
A、He teaches chemistry at MU. B、He is working on a nuclear energy source. C、He developed a chemical battery. D、He made a breakthrough in computer engineering.
(2)、Jae Kwon gave examples in Paragraph 4 _________.
A、to introduce nuclear batteries can be safely used B、to show chemical batteries are widely applied C、to introduce various energy sources D、to describe a nuclear-powered system
(3)、Liquid semiconductor is used to _________.
A、get rid of the radioactive waste B、test the power of nuclear batteries. C、reduce the damage to lattice structure. D、decrease the size of nuclear batteries

    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

    The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

    Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.

    After finishing my teaching for a school year, I thought that I should go back to Montreal, Quebec, my hometown for a visit. My main goal was to relax in preparation for the challenges of my retirement in the coming year.

    Through my stay in Montreal, I met lots of Chinese who are struggling to succeed and then lead a better life in Canada.

    Some travelled thousands of miles to get knowledge. When I spoke with some of them about the major barrier they had to face after they arrived in Canada, they all talked about the two official languages of Canada. But I was impressed by their ability to express their ideas while switching between English and French.

    Almost all of those people said they often felt homesick. They miss their families and friends. Though Montreal has lots of Chinese restaurants, they long for a home-cooked meal.

    I met some tourists who were trying to realize their childhood dreams of experiencing the life in a developed country. When I asked them if Montreal had lived up to their expectations, they hesitated. They said that reality never agrees with fantasies. However, they were glad to have the opportunity to visit Montreal and didn't regret taking the trip.

    Not all the Chinese people I met were happy. I once met a young lady who met with a gentleman through the Internet. However, to her disappointment, he disappeared after he promised to marry her in Montreal.

    I was served by another Chinese person who could not handle the challenges of studying in an English environment and ended up working in a restaurant with minimum pay.

    Exploring different parts of the world, without any doubt, is an amazing experience. However, one should be realistic when it comes to leaving his hometown to set up a new life in a foreign country. One should take the time to examine the advantages and the shortcomings of the venture before they decide to chase an uncertain dream of achieving success or leading a better life.

    Traveling to Europe to see its famous monuments like the Eiffel Tower in Paris and the Colosseum(古罗马竞技场)in Rome, is not exactly the ideal vacation for kids. Fortunately, Europe has more to offer than lots of old churches and ancient history. You can enjoy some fun with your kids in the sun at some of the famous beaches of the continent.

    Mykonos, Greece

    The closer you get to the equator, the longer the beach season is, and Greece is wonderful for that. You can enjoy beautiful green water, public chairs and lovely umbrellas at the beaches in Mykonos.

    Dubrovnik, Croatia

    There's nothing more attractive than the beautiful beaches bordering Dubrovnik, Croatia's most beautiful city. It's surrounded by stone walls like a castle. It almost makes you feel like you're suntanning(晒黑皮肤)at Hogwarts, where the hero Harry Potter of the story is trained!

    Sicily, Italy

    Rabbit Beach on the island of Sicily offers shallow and crystal clear waters, making it a perfect beach for families with young children. And if you want to add interest to your experience, try snorkeling(徒手潜水).

    Nice, France

    Lined with palm trees and first-class hotels, the city of Nice, located on the French Riviera, offers a whole coastline of Mediterranean beaches. Because they're in the heart of the city, these beaches attract a large crowd. So if you're looking for something more private, you'll have to travel a few miles outside of the city center.

    Ribadeo, Spain

    At low tide, Playa de las Catedrales in Ribadeo, Spain is the perfect beach to take in the natural wonders without urban amusements like restaurants, bars or huge crowds. It boasts beautiful wild flowers and unique rock formations making it truly a picture worthy.

Parties and social gatherings no longer excite us the same way they once did. This is not due to a lack of desire to socialize, but the smartphone.

At parties, people focus more on their smartphones than on their drinks. According to a recent study from International Data Corporation,over half of all Americans have a smartphone and reach it the moment they wake up, keeping it in hand all day. In addition, too many people are using smartphones while driving and as a result, they get into car crashes. 34 percent of teens admit to text while driving, and they confirm that texting messages are the major interruption while driving. People's attachment (依恋) to their smartphones is unbelievably becoming more important than the lives of themselves and others.

Just as drivers dismiss the importance of focusing while on the road, many people also fail to recognize the significance of human interaction. When with their friends, some people pointlessly (无谓地) check or send messages in the presence of their friends., which means that their friends are less important. In addition, relying on our smartphones to make friends does not give us the same advantages as making new friends in the real world. Face-to-face conversations will give us the chance to improve our communication skills in the long run.

As many people risk their lives and the lives of people around them just to send a text or mindlessly check their messages, smartphones are in many ways more dangerous to people. The technology shows the achievement weaken the value of communication. Not only is the smartphone affecting our desire to interact face to face, but it is also lowering people's ability to communicate.
