单选题Uncle Sam is a tall, thin man. He's an older man with white hair and a white beard. He often wears a tall hat, a bow tie, and the stars and stripes of the American flag. Who is this strange-looking man? Would you believe that Uncle Sam is the U.S. government? But why do you call the U.S. government Uncle Sam? During the War of 1812, the U.S. government hired meat packers to provide meat to the army. One of these meat packers was a man named Samuel Wilson, Samuel was a friendly and fair man. Everyone liked him and called him Uncle Sam. Sam Wilson stamped the boxes of meat for the army with a large U,S. for United States. Some government inspectors came to look over Sam's company. They asked a worker what the U.S. on the boxes stood for. As a joke, the worker answered that these letter stood for the name of his boss, Uncle Sam. The joke spread, and soldiers began saying that their food came from Uncle Sam. Before long, people called all things that came from the government "Uncle Sam". "Uncle Sam" became a nickname for the U.S. government. Soon there were drawings and cartoons of Uncle Sam in newspapers. In these early pictures, Uncle Sam was a young man. He wore stars and stripes, but his hair was dark and he had no beard. The beard was added when Abraham Lincoln was President. President Lincoln had a beard. The most famous picture of Uncle Sam is on a poster from World War I. The government needed men to fight in the war. In the poster, a very serious Uncle Sam points his finger and says "I want YOU for the U.S. Army./

单选题Nuclear power"s danger to health, safety, and even life itself can be summed up in one word: radiation. Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can"t be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can"t sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being outright by killing masses of cell in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit, and if they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells arc only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or liable to serious illness as a result of radiation absorbed by its grandparents. It is not too careful to prevent from the radiation. Radiation can hurt us. We must know the truth.

单选题Sporting activities are essentially modified forms of hunting behaviour. Viewed biologically, the modern footballer is in reality a member of a hunting group. His killing weapon has turned into a harmless football and his prey into a goal-mouth. If his aim is accurate and he scores a goal, he enjoys the hunter's triumph of killing his prey. To understand how this transformation has taken place we must briefly look back at our forefathers. They spent over a million years evolving as cooperative hunters. Their very survival depended on success in tie hunting-field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They cooperated as skillful male-group attackers. Then about ten thousand years ago, after this immensely long period of hunting their food, they became farmers. Their improved intelligence, so vital to their old hunting life, was put to a new use—that of controlling and domesticating their prey. The hunting became suddenly out of date. The food was there on the farms, awaiting their needs. The risks and uncertainties of the hunting were no longer essential for survival. The skills and thirst for hunting remained, however, and demanded new outlets. Hunting for sport replaced hunting for necessity. This new activity involved all the original hunting sequences but the aim of the operation was no longer to avoid starvation. Instead the sportsmen set off to test their skill against prey that were no longer essential to their survival. To be sure, the kill may have been eaten but there were other much simpler ways of obtaining a meaty meal.

单选题{{B}}Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A,B,C and D. Choose the best answer and blacken the corresponding letter on the Answer Sheet.{{/B}}{{B}}Passage One{{/B}} Long time ago, the ancient people could not travel to any far away places for they had no vehicle to carry them across the wide oceans, deep valleys, long rivers or high mountains. Nowadays people take advantage of steamships, trains, airplanes and modern bridges. Airplanes can carry us to the far countries in a short time; steamships can travel across the wide oceans. It is convenient to the modern people. Travelling is a good idea to us because we can get more knowledge, such as the customs, the geography of other countries. And people could travel among the different countries in the world. For it is easy to travel from the land by trains, or from the sea by ships. We learnt that the Italian who made the world large was Mr. Columbus. He was a brave man. Up to the middle of the 15th century, the people were afraid of traveling because they believed it was a dangerous thing. There is a saying in China, which is "Travelling for thousands is better than reading for ten years." It is to say that we can learn more in different places than we can learn from books.

单选题As a giant of the stock market, Apple is unusual. For much of the past 20 years, three companies have alternated in the role of the largest on the American stock market: Exxon Mobil, General Electric and Microsoft. The first two are very big companies by Apple standards. But Apple offers the kind of growth prospects that the shareholders of Exxon Mobil and GE can only dream of. Its sales in the latest quarter were almost double those of the previous year, and forecasts for 2013 revenues are nearly treble those recorded in 2010. It is the epitome of the modern company: short on physical capital but long on brainpower. So what does Apple"s dominance reveal about the economy and the stock market? First, it is a powerful reminder that the free market can still be remarkably innovative. In the past 11 years Apple has launched three products—the iPod, iPhone and iPad—that have created brand new markets, fulfilling desires that consumers did not even know they had. It is impossible to imagine any of those designs being dreamed up by a bureaucrat. Second, it shows that the internet industry has come of age . The dotcom bubble of the late 1990s featured companies that were heavy on ideas but light on revenues or profits. When the bubble burst a decade ago, it was feared that the internet would savage margins by "commoditizing" devices like phones and personal computers. Apple has so far proved that it is possible to earn high margins with brilliant design and by offering consumers ways to access the internet effortlessly wherever they go. It has made the mobile era its own. Third, Apple"s rise shows that, even in a period of austerity, consumers are willing to pay for the must-have gadget. The company is a huge beneficiary of globalization: able not only to source its products at low cost in Asia but to sell the finished goods there as well. A global elite is now willing to pay for the most desirable products, from luxury luggage to premium Scotch. And America"s soft power is still so strong that it can create aspiring brands for that elite. But does Apple"s surge to preeminence indicate that the stock market is back to the insane days of the late 1990s? There are certainly warning signs. Brokers are competing to come up with the highest potential price target for Apple"s shares, and the announcement of a share buy-back should remind investors that companies have a tendency to purchase their own equity at market peaks. But when Cisco, a technology giant, was briefly worth more than $500 billion in 2000, its price-earnings ratio was above 100; Apple trades on only 22 times its 2011 profits. Its new dividend yield will be almost as generous as that of the overall market. Even if its shares turn out to be overvalued, this would be more like a pimple than a bubble.
