单选题The Forbidden Apple New York used to be the city that never sleeps. Theses days, it"s the city that never smokes, drinks or does anything naughty (at least, not in public). The Big Apple is quickly turning into the Forbidden Apple. If you wanted a glass of wine with your picnic in Central Park, could you have one? No chance. Drinking alcohol in public isn"t allowed. If you decided to feed the birds with the last crumbs (碎屑) of your sandwich, you could be arrested. It"s illegal if you went to a bar for a drink and a cigarette, that would be OK, wouldn"t it? Er...no. You can"t smoke in public in New York City. What"s going on? Why is the city that used to be so open-minded becoming like this? The mayor of New York is behind it all. He has brought in a whole lot of new laws to stop citizens from doing what they want, when they want. The press is shocked. Even the New York police have joined the argument. They recently spent $100,000 on a "Don"t blame the cop" campaign. One New York police officer said, "We raise money for the city by giving people fines for breaking some very stupid laws. It"s all about money." The result is a lot of fines for minor offences. Yoav Kashida, an Israel tourist, fell asleep on the subway. When he woke up, two police officers fined him because he had fallen asleep on two seats (you mustn"t use two seats in the subway). Elle and Serge Schroitman were fined for blocking a driveway with their car. It was their own driveway. The angry editor of vanity Fair magazine, Graydon Carter, says, "Under New York City law it is acceptable to keep a gun in your place of work, but not an empty ashtray (烟灰缸)." He should know. The police came to his office and took away his ashtray. But not all of the New York"s inhabitants are complaining. Marcia Dugatty, 72, said, "The city has changed for the better. If more cities had these laws, America would be a better place to live," Nixon Patricks, 38, a barman, said, "I like the new laws, if people smoked in here, we"d go home smelling of cigarettes." Recent figures show that New York now has fewer crimes per 100,000 people than 193 other US cities. And it"s true. It"s safe, cleaner and more healthy than before. But let"s be honest, who goes to New York for its clean streets?

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 trapped 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 (滑坡) 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. In that way, they will have time to escape from the dangerous gases.

单选题TV Games Shows One of the most fascinating things about television is the size of the audience. A novel can be on the "best sellers" list with a sale of fewer than 100, 000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything or anyone well known overnight. This is the principle behind "quiz" or "game" shows, which put ordinary people on TV to play a game for the prize and money. A quiz show can make anyone a star, and it can give away thousands of dollars just for fun. But all of this money can create problems. For instance, in the 1950s, quiz shows were very popular in the U.S. and almost everyone watched them. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show's producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn't like the person who won the game, they turned the show off. Based on his story, a movie under the title Quiz Show is on 40 years later. Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren't taken as seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions.

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}} How to Read{{/B}} A few years ago I was shopping with a friend and his 12 year-old daughter in downtown San Francisco. A street musician, whom my friend happened to know from his own musician days, was playing the saxophone(萨克斯管)on a street corner. His name was Clifford, and he had attracted a large crowd with his performance. After he finished, my friend introduced him to me and his daughter. Clifford asked her if she played any instrument. When she replied that she was taking trumpet(小号)lessons and played in her junior high school band, he said, "That's fine, little lady. Learn your instrument well and you can play anything." Somehow these simple yet wise words struck me as appropriate not only for a trumpet player but also for a reader. If you learn to read well, you can read anything you want--not just newspapers and magazines, but more difficult material like philosophy, film criticism, military history-whatever interests you as your confidence grows. You would not be limited in any way. If you have the vocabulary or at least a good dictionary near at hand-you can pick up a book, concentrate in it, and make sense of the author's words. In the United States, reading instruction often ends at elementary school, so students sometimes have difficulty as they progress through school. They must take their assignments armed only with their elementary school reading skills. The result, too often, is frustration and loss of confidence. And the assigned reading in your college courses will be even greater than they were in high school. Developing Reading Skills is designed to accomplish several tasks: to show you the skills that will enable you to read with greater comprehension, to help you cope with reading assignments With confidence, and to teach you to become an active reader.

单选题Good evening, ladies and gentlemen, and welcome. I'm sure we have all heard of the expression "Think green". Tonight we are going to talk about" Act green" in our everyday life. The best place to start, of course, is in nut home. Every day people all over the world are hurting the environment without even knowing it. For example, busy families buy paper napkins and plastic food wrap at the supermarket. This helps them save time oil housework. But after these things have been used, what happens to them? They go into the garbage can. In many places, especially in North America big cities are running out of places to throw their garbage. What can we do about it? How can we cut down on garbage? Now we can use plastic: napkins and plastic towels instead of paper towels. When we go grocery shopping we can choose products that are not over-packaged. For example, last week I bought a package of cookies in a hag. There was a plastic tree inside the bag, and then each cookie was in its own package on the tree in the bag. That's over-packaging. We should also take our own bags to the grocery store to carry the things home in. What does the speaker's attitude towards over-packaging according to the speech?A. It helps us save time.B. It adds to the problem of too much garbage.C. It is a kind of waste of resources.D. It is a good way to make things look nic
