单选题No country in the world has more daily newspapers than the USA. There are almost 2000 of them, as compared with 180 in Japan, 164 in Argentina and 111 in Britain. The quality of some American papers is extremely high and their views are quoted all over the world. Distinguished dailies like the Washington Post or the New York Times have a powerful influence all over the country. However the Post and the Times are not national newspapers in the sense that The Times is in Britain or Le Monde is in France, since each American city has its own daily newspaper. The best of these present detailed accounts of national and international news, but many tend to limit themselves to state or city news. Like the press in most other countries, American newspapers range from the "sensational", which feature crime, sex and rumour, to the serious, which focus on factual news and the analysis of world events. But with few exceptions American newspapers try to entertain as well as give information, for they have to compete with television. Just as American newspapers give way to all tastes, so do they also try and apply to readers for all political persuasions. A few newspapers support extremist (过激分子) groups on the far right and on the far left, but most daily newspapers attempt to attract middle-of-the-road Americans who are essentially moderate. Many of these papers print columns by well-known journalists of different political and social views, in order to present a balanced picture. As in other democratic countries American newspapers can be either responsible or irresponsible, but it is generally accepted that the American press serves its country well and that it has more than once bravely uncovered political scandals (丑闻) or crimes, for instance, the Watergate Affair. The newspapers drew the attention of the public to the fears of the Vietnam War.

单选题Which of the following factors will not affect the time of the tide?

单选题We used to think that the left brain controlled your thinking and that the right brain controlled your heart. But neuroscientists have learned that it's a lot more complicated. In 2007, an influential paper in the journal Behavioral and Brain Functions found that while most of us process emotions through the right hemisphere of the brain, about 35 % of people—especially victims of trauma—process their hurt and anger through their left brain, where logic and language sit. That may be because they had worked so hard to explain, logically, why they were suffering. But pushing emotions through the left brain taxed it: these people performed significantly worse on memory tests. Now a new paper—out in the September issue of The Journal of Nervous and Mental Disease—further complicates the picture with a surprising finding: whether you are right-handed, left-handed or ambidextrous (which the authors call, rather delightfully, " inconsistently handed") seems to be an important clue in understanding how you use your brain to process emotions. It's been known for some time that lefties and the ambidextrous are more prone to negative emotions. The new study shows that they also have a greater imbalance in activity between the left and right brains when they process emotions. Of course, you can't be sure which comes first: maybe angry people are more out of balance, or maybe the inability to find equilibrium makes you angry. As for the left-handed: maybe they're more angry because the world is designed for the right-handed majority. The study also used an interesting method to find that angry people are, literally, hot-headed: the authors of the paper—led by Ruth Propper, a psychology professor at Merrimack College in Massachusetts- measured brain-hemisphere activation with a relatively old method called tympanic membrane temperature, which is essentially how hot it is in your inner ear. If you get angry a lot, your head tends to be warmer. One problem is that the study was small —just 55 undergraduates participated (they were paid $20 each for having to endure ear-temperature tests and psychological questioning). Also, The Journal of Nervous and Mental Disease, while peer-reviewed, is one of less-respected psychology journals. Still, I like the study just because it explains that when you get hot under the collar, you are actually hot under the collar.

单选题A hundred years ago, the game we now call football did not exist. American football started during a game between two colleges. The teams had got together to play what they called "football", but each team played by different roles. One team played what we now call soccer. The other played what we now call rugby (橄榄球) . Both games had been invented a thousand years before. In the first kind of football game ever played, all the men from one village tried to kick a ball into another village. The men of the second village tried to kick the ball into the first. Hundreds of people joined in, running everywhere, running crops and knocking down fences. In time, people agreed on some rules to keep order, but many rules were left open to change. Different rules developed in different places. When the two colleges met to play football, each followed its own rules. They mixed the games together and invented a new game. A hundred years later we call that game American football. In what ways do you suppose the game we know now will have changed in another hundred years?
