单选题 Benefited or Hurt For the most part, it seems, workers in rich countries have little to fear from globalization, and a lot to gain. But is the same thing true for workers in poor countries? The answer is that they are even more likely than their rich country counterparts to benefit, because they have less to lose and more to gain. Orthodox economics takes an optimistic line on integration and the developing countries. Openness to foreign trade and investment should encourage capital to flow to poor economies. In the developing world, capital is scarce, so the returns on investment there should be higher than in the industrialized countries, where the best opportunities to make money by adding capital to labor have already been used up. If pool countries lower their barriers to trade and investment, the theory goes: rich foreigners will want to send over some of their capital. If this inflow of resources arrives in the form of loans or portfolio investment, it will supplement domestic savings and loosen the financial constraint on additional investment by local companies. If it arrives in the form of new foreign controlled operations, FDI, so much the better: this kind of capital brings technology and skills from abroad packaged along with it, with less financial risk as well. In either case, the addition to investment ought to push incomes up, partly by raising the demand for labor and partly by making labor more productive. This why workers in FDI receiving countries should be in an even better position to profit from integration than workers in FDI sending countries. Also, with or without inflows of foreign capital, the same static and dynamic gains from trade should apply in developing countries as in rich ones. This gain from trade logic often arouses suspicion, because the benefits seem to come from nowhere. Surely one side or the other must lose. Not so. The benefits that a rich country gets though trade do not come at the expense of its poor country trading partners, or vice versa. Recall that according to the theory, trade is a positive sum game. In all these transactions, sides exporters and importers, borrowers and lenders, shareholders and workers can gain.

单选题 下面有3篇短文，每篇短文后有5道题，每题后面有4个选项。请仔细阅读短文并根据短文回答其后面的问题，从4个选项中选择1个最佳答案。{{B}}第一篇{{/B}} {{B}} Shakespeare{{/B}} When talking about the world's greatest poet and greatest dramatist, only one name can possible suggest itself;that of William Shakespeare. Nearly every Englishman has some knowledge, however slight, of the work of this greatest writer. We use words, phrases and quotations form Shakespeare's writings that have become part of the common property of English-peaking people. Most of the time we are probably unaware of the source of the words we use. For example, and old lady, after seeing a performance of Hamlet complained, "It was full of well-known proverbs and quotations!" Shakespeare made full use of the great resources of the English language. Most of us use about five thousand words in our normal employment of English; Shakespeare in his works used about twenty-five thousand! There is probably no better way for a foreigner (or an Englishman) to appreciate the richness and variety of the English language than by studying the various ways in which Shakespeare used it. Such a study is well worth the effort, even thought some aspects of English and the meaning of many words, have changed since Shakespeare's day. It is a pity that we know so little about the life of the greatest English author. We only know that he was born in 1564 in Stratford on Avon, and that then died there in 1616. He almost certainly attended the Grammar School in the town, but of this we cannot be sure. We know he was married there in 1582 and had three children. We know that he spent much of his life in London, writing his masterpieces. But this is almost all that we do know. However, what is important about Shakespeare's life is not its incidental details but its products, the plays and the poems. For many years scholars have been trying to add a few facts about Shakespeare's life to the small number we already posses and for an equally long time critics have been theorizing about the plays. Sometimes indeed, it seems that the poetry of Shakespeare will disappear beneath the great mass of comment that has been written upon it. Fortunately this is not likely to happen. Shakespeare's poetry and Shakespeare's characters (Macbeth, Othello, Hamlet and all the others) have long delighted not just the English but lovers of literature everywhere, and will continue to do so after the scholars and commentators and all their works have been forgotten.

单选题Water From the beginning, water has furnished man with a source of food and a highway to travel upon. The first 16 arose where water was a dominant element in the environment, a challenge to man"s ingenuity. The Egyptians invented the 365-day calendar 17 the Nile"s annual flooding. The Babylonians, who were among the most famous law-makers in ancient times, invented laws 18 water usage. Water inspired the Chinese to build a 1,000- 19 canal, a complex system which, after nearly 2,500 years, remains still practically 20 and still commands the astonishment of engineer. But the 21 never found complete solutions to their water problems. The Yellow River is also known 22 "China"s Sorrow"; it is so unpredictable and dangerous 23 in a single flood it has caused a million 24 . Floods slowed the great civilization of the Indus River Valley, and inadequate drainage ruined 25 of its land. Today water dominates 26 as it always has done. Its presence continues to 27 the location of his homes and cities; its violent variability can 28 man of his herds or his crops; its routes links him 29 his fellows; its immense value may 30 to already dangerous political conflicts. There are many examples of this in our own time.

单选题The Exploding Lakes of Cameroon What comes to mind when you think of a lake? You probably imagine a pretty scene with blue water, birds, and fish. For the people in the northwestern Cameroon, however, the image is very different. For them, lakes may mean terrible disasters. In 1984, poisonous gases exploded out of Lake Monoun and came down into the nearby villages, killing thirty-seven people. Two years later, Lake Nyos erupted a cloud of gases rolled down the hills and into the valleys and killed 1,700 people. Lake Nyos and Lake Monoun are crater (火山口) lakes. They were formed when water collected in the craters of old volcanoes. The volcanoes under Lake Nyos and Lake Monoun are not active anymore. However, poisonous gases from the center of the earth continue to flow up through cracks in the bottom of the lake. This is normal in a crater lake. In most crater lakes, these gases are released often because the water "turns over" regularly. That is, the water from the bottom of the lake rises and mixes with the water at the top, allowing the gases to escape slowly. However, in Lakes Nyos and Monoun, there is no regular turning over. No one knows the reason for this fact, but as a result, these lakes have more gases tapped at the bottom than other crater lakes. In fact, scientists who have studied Lakes Nyos and Monoun have found 16,000 times more gases. When a strong wind, cool weather a storm, or a landslide causes the water to turn over suddenly, the gases escape in a violent explosion. In the past, no one knew when the gases might explode, so there was no way for the villagers to escape disaster. Now scientists from the United States, France, and Cameroon have found a way to reduce the gas pressure at the bottom of Lake Nyos. They stood a 672-foot plastic pipe in the middle of the lake, with one end of the pipe near the bottom and the other end in the air. Near the top of the pipe, the team put several holes that could be opened or closed by a computer. Now, when the gas pressure gets too high, the holes are opened and some of the gas-filled water shoots up through the pipe into the air like a fountain. With less pressure, a disastrous explosion is much less likely. However, the scientists are not sure that one pipe will be enough to prevent explosions. They hope to put in others soon and they plan to install a similar pipe and a computer system at Lake Monoun as well. To protect people nearby until all of the pipes are in place, the scientists have installed early warning systems at both lakes. If the gas pressure rises to a dangerous level, computers will set off loud sirens (警报) and bright lights to warn the people in the villages. That way, they will have time to escape from the dangerous gases.

单选题Mother Nature Shows Her Strength Tornadoes (龙卷风) and heavy thunderstorms moved across the Great Lakes and into Trumbull County on Saturday evening. The storms were dramatic and dangerous. George Snyder was driving the fire truck down Route 88 when he first noticed that a funnel (漏斗状的) cloud was behind him. "I stopped the truck and watched the funnel cloud. It was about 100 feet off the ground and I saw it go up and down for a while. It was moving toward Bradley Road and then suddenly it disappeared," Snyder said. Snyder only saw one of the funnel clouds that passed through northeastern Ohio on Saturday. In Trumbull County, a tornado turned trees onto their sides. Some trees fell onto houses and cars. Other trees fell into telephone and electrical wires as they went down. Amanda Symcheck was having a party when the storm began. "I knew something was wrong," she said. "I saw the sky go green and pink (粉红色). Then it sounded like a train rushing toward the house. I started crying and told everyone to go to the basement for protection." The tornado caused a lot of damage to cars and houses in the area. It will take a long time and much money to repair everything. There was also serious water damage from the thunderstorms. The heavy rains and high wind caused the power to go out in many homes. The storms caused serious flooding in areas near the river. More than four inches of rain fell in parts of Trumbull County. The river was so high that the water ran into streets and houses. Many streets had to be closed to cars and trucks because of the high water. This made it difficult for fire trucks, police cars, and other rescue vehicles to help people who were in trouble. Many people who live near the river had to leave their homes for their own safety. Some people reported five feet of water in their homes. Local and state officials opened emergency shelters for the people who were evacuated (撤走). The Red Cross served meals to them. "This was a really intense storm," said Snyder, "People were afraid. Mother Nature can be fierce. We were lucky this time. No one was killed."

单选题California Gives Green Light to Space Solar Power Energy beamed down from space is one step closer to reality, now that California has given the green light to an agreement that would see the Pacific Gas and Electric Company buy 200 megawatt (兆瓦) of power beamed down from solar-power satellites beginning in 2016. But some major challenges will have to be overcome if the technology is to be used widely. A start-up company called Solaren is designing the satellites, which it says will use radio waves to beam energy down to a receiving station on Earth. The attraction of collecting solar power in space is the almost uninterrupted sunshine available in eosynchronous (与地球同步的) orbit. Earth-based solar cells, by contrast, can only collect sunlight during daytime and when skies are clear. But space-based solar power must grapple (努力克服) with the high cost per kilogram of launching things into space, says Richard Schwartz of Purdue University in West Lafayette, Indiana, "If you're talking about it being economically viable or power of the Earth, it's a tough go." he says. Cal Boerman, Solaren's director of energy services, says the company designed its satellites with a view to keeping launch costs down. "We knew we had to come up with a different, revolutionary design," he says. A patent the company has won describes ways to reduce the system's weight, including using inflatable minors to focus sunlight on solar cells, so a smaller number can collect the same amount of energy. But using minors introduces other Henges, including keeping the solar cells from overheating, says Schwartz. "You have to take care of heat dissipation (散发) because you're now concentrating a lot of energy in one place," he says. According to the company's patent, Solaren's solar cells will be connected to radiators to help keep them cool. Though Boerman says the company believes it can make space-based solar power work, it is not expecting to crowd out other forms of renewable energy. Laws in California and other states require increasing use of renewable energy in coming years, he points out. "To meet those needs, we're going to need all types of renewable energy sources," he says.
