单选题 请阅读Passage 2。完成第小题。 The relationship between formal education and economic growth in poor countries is widely misunderstood by economists and politicians alike. Progress in both area is undoubtedly necessary for the social, political and intellectual development of these and all other societies; however, the conventional view that education should be one of the very highest priorities for promoting rapid economic development in poor countries is wrong. We are fortunate that is it, because new educational systems there and putting enough people through them to improve economic performance would require two or three generations. The findings of a research institution have consistently shown that workers in all countries can be trained on the job to achieve radical higher productivity and, as a result, radically higher standards of living. Ironically, the first evidence for this idea appeared in the United States. Not long ago, with the country entering a recessing and Japan at its pre-bubble peak, the U.S. workforce was derided as poorly educated and one primary cause of the poor U.S. economic performance. Japan was, and remains, the global leader in automotive-assembly productivity. Yet the research revealed that the U.S. factories of Honda, Nissan, and Toyota achieved about 95 percent of the productivity of their Japanese counterparts--a result of the training that U.S. workers received on the job. What is the real relationship between education and economic development? We have to suspect that continuing economic growth promotes the development of education even when governments don't force it. After all, that's how education got started. When our ancestors were hunters and gatherers 10,000 years ago, they didn't have time to wonder much about anything besides finding food. Only when humanity began to get its food in a more productive way was there time for other things. As education improved, humanity's productivity potential increased as well. When the competitive environment pushed our ancestors to achieve that potential, they could in turn afford more education. This increasingly high level of education is probably a necessary, but not a sufficient, condition for the complex political systems required by advanced economic performance. Thus poor countries might not be able to escape their poverty traps without political changes that may be possible only with broader formal education. A lack of formal education, however, doesn't constrain the ability of the developing world's workforce to substantially improve productivity for the foreseeable future. On the contrary, constraints on improving productivity explain why education isn't developing more quickly there than it is. The author holds in Paragraph I that the importance of education in poor countries_________. A． is subject to groundless doubts B． has fallen victim to bias C． is conventionally downgraded D． has been overestimated

Recycling Electronic Waste When Alex Lin was 11 years old， he read an alarming article in the newspaper which said that people were burying old computers in backyards， throwing TVs into streams， and dumping （丢弃） cell phones in the garbage. This was dangerous because e-waste contains harmful chemicals that can leak into the environment， getting into crops， animals， water supplies-and people. Alex was really worried and decided to make it next project for WIN-the Westerly Innovations Network. Alex and six of his friends had formed this organization to help solve community problems two years before. But what could they do about this project with e-waste？ The team spent several weeks gathering information about the harmful chemicals in e-waste and their effects on humans. They learned how to dispose （处置） of e-waste properly and how it could be recycled. Then， they sent out a survey and found only one in eight knew what e-waste was， let alone how to properly dispose of it. Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students， asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days， and they collected over 9，500 kilograms of e-waste. The next step was to set up a long-term e-waste drop-off center for the town. After some research，they'd learned that reusing is the best way to deal with electronic devices and it is seven times more efficient than recycling. So， they began learning to refurbish（翻新）computers themselves and distributed them to students who didn't have their own. In this way， they could help students in the area and protect the environment at the same time. For a lasting solution to e-waste， the drop-off center wasn't enough. Laws would have to be passed. In 2016， WIN helped push for an e-waste bill in their town， which required companies that manufactured or sold electronics to take back e-waste. The bill clearly forbids the dumping of e-waste. Because of the work of WIN，more and more people，like Alex and his team，are getting the message about safe disposal of e-waste. As Alex says，"Today's technology should not become tomorrow's harmful garbage."（1）What was Alex's worry after he read the article？ ____ A. The littering of e-waste.B. The recycling of plastic.C. The change of environment.D. The overuse of old computers.（2）What did Alex do to start the project？ ____ A. Set up WIN.B. Collect information.C. Ask friends for help.D. Carry out a survey.（3）Which can best describe the way Alex and his team did their work？ ____ A. Traditional.B. Competitive.C. Scientific.D. Convenient.（4）What message does the story convey？ ____ A. There is no end to perfection.B. Success comes through failure.C. Every positive attitude has a reward.D. Young people can make a big difference.

Reuters: the Business of News One of the world’s biggest suppliers of news and financial information, Reuters Group PLC, has a worldwide network of 2000 journalists and provides news stories, photographs and videos to newspapers, televisions and Internet sites. Although it is better known as a press agency, Reuters in fact makes most of its profits through promoting financial information such as currency rates and stock prices to bankers and investors all over the world. The history of Reuters goes hand in hand with improvements in communication technology. Reuters was established by Paul Julius Reuter-originally a bookseller in Germany. He set up a service using carrier pigeons to fly stock prices between Aachen in Germany, where the German telegraph line ended, and Brussels in Belgium, where the Belgian telegraph line began. In 1851, London had an important place in the global telegraphic network, because of which Reuter moved into an office near the London stock exchange from where he supplied investors in London and Paris with stock prices over the new Dover-Calais telegraph line. He expanded the service to include news items and had offices throughout Europe by the late 1850s. As overland and undersea cables were laid, the business of Reuters expanded to the Far East in 1872 and South America in 1874. Its reputation also grew with a number of scoops. For example, Reuters was the first in Europe to announce President Lincoln’s death in 1865. Reuter retired in 1872 and the company changed its name to Reuters Ltd. In 1923, Reuters began to use teleprinters to distribute news to London newspapers and to supply news to Europe. After the growing pressure from the British government for Reuters to serve British interests, the company was restructured in 1941 in order to maintain its independence as agency. (69) At the same time, in the face of competition from American agencies after World War Two, Reuters expanded its financial information services. In 1964, Reuters introduced Stockmaster, which transmitted stock information from around the world onto computer screens. In 1973, the launch of the Reuters monitor created an electronic marketplace for foreign currency by displaying currency rates in real time. Reuters expanded this to include news and other financial information. This was followed by the Reuters monitor dealing service in 1981, which allowed foreign currency traders to trade directly from their own computers. In the 1990s, Reuters continued to develop information systems, including multimedia and online services. It bought a number of companies, including a television company which was called Reuters Television, which provides news, sports, business and entertainment via satellite to broadcasters in more than 90 countries. (70) Today’s Reuters is still based on its Trust Principles, which state that news and information from the company must be independent and free from bias. Reuters’journalists have to provide accurate and clear descriptions of events so that individuals, organizations and governments can make their own decisions based on facts. Answer the following questions according to the passage. 1.How does Reuters get most of its money

Some people who like to eat very hot chili（辣椒）peppers say that they can help you breathe better if you have a cold. Others believe that chilies give you added energy. We cannot tell you these ideas are true or false. But what we know for sure is that people have been growing chilies for centuries, and there are many kinds, about two hundred.Want to fire up your meals with homegrown chilies? Here are some ideas for you to make it come true. Follow these steps and enjoy your farming life at home.Chilies need a warm climate to grow better. Nothing is more important than enough heat for the growth. If you plant the seeds outside when the weather is cool, place the seeds under a glass. That will add warmth from the sun and protect them from wind. What's more, it helps make the temperature high than outside.If you plant inside, fill a pot（something to hold the seed）with soil. The pot should have holes in the bottom so water can run out. Drop several seeds onto the pot and cover them with some soil. Then cover the top of the pot with a plastic bag. Hold the pot in a warm area.When the chilies start growing, take off the bag. When the plants have reached about two centimeters high, take them out and place each one carefully in its own pot.When the plants are twenty centimeters high, tie the plants to a stick placed in the pot so that they will not fall down.When the chili peppers are thirty centimeters high, remove the tops off with your fingers. That should make new branches grow. When the first flowers show, give the plants some potash fertilizer（化肥）. When the weather is warm, place them outside. Make sure they get a good amount of light and water.Some people like to pick chilies when they are green. Others like to pick them when they are red. Both of them give colors, taste and differing amounts of heat to the soups, dish and other foods.The most important condition that chili seeds need in cool weather is .A.low temperatureB.enough waterC.enough heatD.no windWhat's the RIGHT order to plant chilies inside? ①Tie the plants to a stick placed in the pot.②Cover the top of the pot with plastic.③Remove the tops off the chili plant.④Drop some seeds onto the soil of the pot.A.③②①④B.④②①③C.①③②④D.①④③②We can know from the passage that .A.there are about 2 thousand kinds of chilies in the worldB.people have grown chilies for several hundred yearsC.chilies can surely make us feel better if we have a coldD.the pot has holes in the bottom to let air inWhere can we most probably read the passage? A. magazine.B.A travel website.C.A textbook.D.A history leaflet.
