阅读短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项。

    Have you ever spent an afternoon in the backyard, maybe grilling or enjoying a basketball game, when suddenly you notice that everything goes quiet? There is an old phrase "calm before the storm", often used in a situation—a quiet period just before a great activity or excitement. According to our own experience, we know there is actually calm before the storm. But what causes this calm? And is it always calm before the storm? Let's hear what scientists have to say.

    A period of calm happens in a particular kind of storm, the simplest kind of storm—a single-cell thunderstorm. In this type of thunderstorm, there is usually only one main updraft, which is warm, damp air and drawn from places near the ground. Storms need warm and damp air as fuel, so they typically draw that air in from surrounding environment. Storms can draw in the air that fit their need from all directions—even from the direction in which the storm is traveling.

    As the warm, damp air is pulled into a storm system, it leaves a low-pressure vacuum (真空) coming after. The rising air meets the cold dry air that has already existed in the storm clouds, thus the temperature of the warm, damp air drops, and the water vapour (水蒸汽) in it changes into tiny drops that are a precondition of rain. These drops accumulate and build on larger particles like dust, until they grow large enough to form raindrops.

    This warm, damp air keeps moving upwards, but it becomes cooler and drier during its trip through cloud. When it reaches the top of the cloud, the air gets spit out (被挤出) at the top. This air is sent rolling out over the big thunderclouds. From there, the air goes down. Warm and dry air is relatively stable, and once it covers a region, that air, in turn, causes the calm before a storm.

    Most thunderstorms, though, don't start with calm. That's because most are actually groups of storms with complex wind patterns. There's so much air moving up and down storm groups that the calm before the storm never happens. Instead, before the storm,让 might be really windy!

(1)、Which best fits the description of a particular kind of storm?
A、A thunderstorm with a single shape. B、A thunderstorm without strong winds. C、A storm with air drawn from every direction. D、A storm fueled by moving air from the ground.
(2)、What does the underlined word "it" in Paragraph 3 refer to?
A、Cold and dry air. B、Warm and dry air. C、Cold and damp air. D、Warm and damp air.
(3)、Which does the writer most likely agree to?
A、Presence of the calm relies on stable air. B、Not all thunderstorms start with the calm. C、The drier the air is, the bigger the storm will be. D、Storm happens without air moving up and down.
(4)、What is the passage mainly about?
A、Causes and effects of a heavy storm. B、A brief description of a peaceful storm. C、A personal experience of a heavy storm. D、An explanation of the calm before a storm.

    The head of China's largest online seller Alibaba does not think China and the United States will have a trade war despite comments from the Trump administration.

    Jack Ma is the chairman of the Alibaba Group. At the World Economic Forum meeting in Davos, Switzerland, he said, "China and (the) U.S. will never have a trade war. Give Trump some time. He's open-minded, he's listening."

    The Chinese billionaire said he would do all he could to prevent trade relations between the countries from getting worse.

    Last week, Ma met with Trump at the Trump Tower in New York City. The Chinese billionaire is said to have discussed a plan to permit one million small U.S. businesses to sell goods on Alibaba's online shopping platform.

    During the campaign and after winning the presidential election, Trump strongly criticized the Chinese government's support for its businesses. He blamed unfair trade policies for taking away U.S. jobs. And he said that China unfairly controls the exchange value of its currency, the yuan.

    Trump also has threatened to place import taxes on goods from China and other countries in response to their trade policies.

    According to the South China Morning Post, Ma said, "American international companies made millions and millions of dollars from globalization." He added that the U.S. should not blame the loss of jobs and companies on globalization.

    However, a new study by an American business group says many U.S. businesses feel unwelcome in China. The companies say the cost of doing business in China is increasing. They add that rules and regulations are unclear or not enforced in a consistent way.

    The American Chamber of Commerce in China led the study, which looked at responses from 462 companies.

    William Zarit is chairman of the chamber. He says trade policies in China make it difficult for American companies. He says, "we feel that over the last few years that we've been taken advantage of to some extent, with our open market and the lack of open areas in the Chinese market."

    Another major concern for U.S. companies in China is fake products. Fake products are copies of the originals that cost businesses with the legal right to sell them millions of dollars each year.

    Ma defended Alibaba's efforts to fight fake products on its shopping platform. He said his company is doing all it can to fight the problem.

    "Fighting against fake products is a war against human greediness," Ma said.

    In choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair­weather friends. They will be with you as long as you have money or luck,but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities of character,especially understanding, honesty and reliability(信任).

    Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person's place, and he tries to think of ways to be helpful. He is also a good listener.

    At the same time, however, a good friend is honest. He does not look for faults in others. He notices their good points. In short, a friend will try to understand me and accept me.

    Another quality of a friend is reliability. I can always depend on a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor,he will do his best to help me. If I am in trouble, he will not run away from me.

    There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience and learn from each other. A good friend has a good sense of humor too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.

    When I meet someone who is reliable, honest, and understanding,I know I've found a friend!

    Last night's meteor(流星) shower left many people in Emerald Valley dissatisfied. They gathered in the suburbs of the city with heavy telescopes,expecting to watch the brightly burning meteors passing through the sky. However, what they found was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead.

    “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing,but it turned out to be a huge disappointment.”

    Astronomers—scientists who study stars and planets—have been complaining about this problem for many years. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.

    Besides professional and amateur(业余的) star observers, there is yet a population that suffers even more from light pollution. This population consists of birds,bats, frogs, and snakes etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International Dark­Sky Association, “100 million birds a year throughout North America die in crashes with lighted buildings and towers. ”

    Countless animals injuries and deaths result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful to humans, too. They worry that exposure to light while sleeping can increase people's chances of getting cancer.

    Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona has enforced lighting rules in its city in order to help astronomers with their observations. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

    There are many different voices on charity donations recently. Chen TianQiao, one of the Chinese billionaires, gave away $115 million to the California Institute of Technology (Caltech) to help promote brain research. Chen has been interested in the brain research, believing it can advance the industries of artificial intelligence and virtual reality. However, this huge donation has caused heated discussion among Chinese scholars and internet users.

    Many criticized him for giving money to a foreign university rather than domestic institutes for brain research, which are developing fast and are catching up with the US in just a few years. RaoYi, a biologist at Peking University, even said the donation was a typical mistake.

    Others, however, support his choice. They believe Caltech is a more reasonable choice compared with Chinese research Institutes. Caltech has a long history and has taken a leading position in biology, and therefore it produces more efficient results. What's more, the results of the research will benefit not only the Americans, but also the rest of the world.

    A similar controversial(有争议的)case started two years ago when Pan ShiYi, chairman of SOHO China, donated $15 million to Harvard University to help disadvantaged Chinese Students.

    Many believe that China is still far behind in management and use of donated money, and that as a result, Chinese donators are looking abroad. In comparison, Western countries like the US, which have a long history of donating money, have well-developed systems that use money efficiently. They can also provide full access for donors who want to track the use of the money. To get more donations, Chinese universities should be braver and more honest. They need self-reflection rather than envy.

    An 18-year-old US girl gained unexpected appreciation and a surprise after she gave “extra help” to an elderly man in the restaurant she was working.

    It's social media that made her seemingly small action go viral and brought her appreciation from hundreds of thousands of strangers and a scholarship to Texas Southern University.

    The heroine Evoni Williams has reportedly been working full-time to earn money for further study in a restaurant in La Marque, Texas,the United States. It was last week when an old man named Adrian Charpentier asked for help to chop his ham for his hands were weak because of illness. On that busy morning when she had loads of work on shoulder, Williams helped the man without hesitation. The moment she was leaning over the counter and cutting the ham was shot by a customer known as Laura Wolf.

    Wolf posted the picture on the Internet and wrote, “I'm thankful to have seen this act of kindness and caring at the start of my day while everything in this world seems so negative. If we could all be like this waitress and take time to offer a helping hand…” According to local reports, Wolf didn't know Williams, neither did Williams know her act was shot and shared on the web. However, the small act of kindness soon accumulated its own power on and outside the Internet.

    Besides praise from netizens and media reports across the United States, a 16000-dollar scholarship to Texas Southern University was recently granted to Williams to support her study plan on business management.

    “We wanted to reward Evoni's act of kindness and let her know that good deeds do not go unnoticed,” said Melinda Spaulding, an administrator at Texas Southern University.

Bogre Udell, who speaks four languages, met Frederico Andrade, who speaks five, at the Parsons New School in New York City.In 2014, they started a project to make the first public records of every language in the world.They've already recorded more than 350 languages, and plan to hit 1,000 in the coming years.

"When humans lose a language, we also lose greater diversity (多样化) in art and traditions,"said Bogre Udell.Between 1950 and 2010, 230 languages disappeared.Today, a third of the world's languages have fewer than 1,000 speakers left.Every two weeks a language dies with its last speaker, and 50 to 90 percent of them are said to disappear by the next century.

Wikitongues has asked for volunteers in 40 countries to film native speakers talking in the past, present,and future tenses of their mother languages.Native speakers are asked to recall childhood, share their stories, and discuss their hopes and goals.One volunteer in the South Pacific islands of Vanuatu recorded a language that had never been studied by language experts before.Another volunteer found a speaker of Ainu, a language in Japan that has no relation to any other known language, and he also recorded it.However, priceless recording opportunities disappear regularly.Not long ago, one of the last two speakers of a Saami language in the Russian steppes died right before his recording session with Wikitongues.

A lack of protection and globalization are responsible for diminishing language diversity.For much of the 20th century, governments across the world forced some local people to use official languages.More than 100 languages in Australia have disappeared since European settlers arrived.However, most languages die today because of other factors; climate change and urbanization contribute (是……的原因之一) greatly to the disappearance of languages.
