Many do not have steady incomes. They might have difficulty borrowing money from an agency in business to make loans. Parents or relatives are usually their best source of loans. Of course, the parents or relatives would have to have money available and be willing to lend it. You might even get an interest-free loan. However, a parent or relative who lends should receive the same interest as any other lender. There are disadvantages in borrowing from parents or relatives. One is that they may not insist on you paying back the money by a certain time. As a result, you might let the loan drag on. This is especially true if you are not required to pay interest. This is not a way to develop good credit habits. For most consumers, the cheapest place to borrow is at a commercial bank. Banks are a good source of installment loan which may run for 12 months or up to 30. Most banks also make single-payment loans to consumers for short periods--30,60 ,or 90 days. The newest type of bank loan is one that a depositor can get simply by writing a check. It is usually called something like "ready credit" or "reserved checking." It works like this. A depositor is given a limited amount of credit, usually between ＄500 and ＄1,000. He or she may write checks up to the amount allowed. Once a check has been written, the amount of the check becomes a loan. Usually no charge is made for interest until the loan is made. A typical interest rate is 3 cents per ＄100 per day, or just under I percent a month. Suppose that you used ＄100 of your credit and repaid it in 30 days. The cost would be 90 cents. If you repaid it in 10 days, the cost would be only 30 cents. The advantage of borrowing from a bank is that banks generally charge lower rates than most other lenders. One reason is that banks have more strict credit requirements than most other lenders. A consumer must have a fairly good credit rating to get a bank loan.

单选题{{B}}第三篇{{/B}} {{B}} The Greatest Show on Earth{{/B}} The Olympic Games (奥林匹克运动会) are the greatest festival of sport in the world. Every four years, a hundred or more countries send their best sportsmen to compete (竞赛) for the highest honors in sport. As many as 6,000 people take part in over 20 sports. For the winners, there are gold medals(奖牌) and glory. But there is honor, too, for all who compete, win or lose. That is in spirit of the Olympics--to take part is what matters. The Olympic Games always start in a bright color and action. The teams of all the nations parade in the opening ceremony(仪式) and march round the track. The custom is for the Greek team to march in first. For it was in Greece that the Olympics began. The team of the country where the Games are being held--the host country--marches in last. The runner with the Olympic torch (火炬) then enters the stadium(体育场) and lights the flame. A sportsman from the host country takes the Olympic oath (誓言) on behalf of all the competitors(竞赛者). The judges and officials also take an oath. After the sportsmen march out of the stadium the host country puts on a wonderful display. The competitions begin the next day. There are usually more than twenty sports in the Games. The rule is that there must be at least fifteen. The main events are in track and field (田径), but it is a few days before these sports start. Each day the competitors take part in a different sport-- riding, shooting, swimming, and cross country running. Points are gained for each event. Medals are awarded (颁发) for the individual winners and for national teams. More and more women are taking part in the games. They first competed in 1900, in tennis and golf, which are no longer held in the Olympics. Women's swimming events were introduced in 1912. But it was not until 1928 that there were any track and field events for women. Now, they compete in all but half a dozen of the sports. In horse riding, shooting, and boat racing, they may compete in the same events as the men.

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 (划破) 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{{B}}第二篇{{/B}} As in the field of space travel, so in undersea exploration new technologies continue to appear. They share a number of similarities with each other — as well as some important differences. Manned submersibles (潜水器), like spaceships, must maintain living conditions in an unnatural environment. But while a spaceship must simply be sealed against the vacuum of space, a submersible must be able to bear extreme pressure if it is not to break up in deep water. In exploring space, unmanned vehicles were employed before astronauts. In undersea exploration, on the other hand, men paved the way, only recently have unmanned remote-operated vehicles (ROVs) been put to use. One reason for this is that communicating with vehicles in orbit is much easier than talking to these underwater. A vacuum am ideal medium for radio communications, but underwater communications are limited to much slower sound waves. Thus, most undersea vehicles—particularly ROVs— operate at the end of long ropes. For a similar reason, knowing where you are undersea is much more difficult than in space. A spaceship's position can be located by following its radio signal, or by using telescopes and radar. For an undersea vehicle, however, a special network of sonar (声纳) must be laid out in advance on the ocean' floor in the area of a dive to locate the vehicle's position. Though undersea exploration is more challenging than outer space in a number of respects, it has a distinct advantage: Going to the ocean depths doesn't require the power necessary to escape Earth's gravity. Thus, it remains far less expensive.

单选题阅读下面这篇短文，短文后列出7个句子，请根据短文的内容对每个句子做出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。 Pubic response to technology often varies in peculiar ways. While biotechnology, for example, gives rise to organized opposition, information technology, which is actually no less invasive(侵害者), no more harmless, is welcomed or, at the least, accepted with comparatively little debate. Information technologies—from computers to communications—have obviously had an overwhelming social impact and their benefits hardly need explanations. But they have also disturbed privacy and threatened civil liberties. Computerized data banks empower bureaucratic authorities by providing easy access to personal information—about credit ratings, social performance, housing and medical histories. They will allow access to genetic figures, providing information about our tendencies to employers, insurers, product advertisers, banks and other institutions that exercise control over our lives. Computerization allows the severe extension of advertising through telemarketing requests that shamelessly intrude our home life. Information technologies have displaced people from jobs and turned potentially skilled workers into low-level computer technicians, computers have facilitated the work of scholars, but also turned them into typists; yet one hears hardly a complaint. They have turned the simple act of buying a plane ticket into an endless manipulation(控制), but we welcome the so-called convenience. They have encouraged new forms of crime and fraud(欺诈), but we describe them with grudging admiration. They have allowed new types of evil weaponry, but we call them "smart bombs". Perhaps the most important, information technologies have extended the power of the mass media, creating unusual possibilities for political manipulation, reducing accountability(有责任，有义务), and changing the nature of political life. It is true that there are critiques(批评) of information technologies from those professionally concerned about their problematic legal, social and political implications. There is a near total absence, however, of organized public concern about technologies with profound and problematic implications.

单选题Japanese Car Keeps Watch for Drunk Drivers A concept car developed by Japanese company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over tired drivers off the road. The car"s sensors check odors inside the car and monitor a driver"s sweat for traces of alcohol. An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver"s palm. Other carmakers have developed similar detection systems. For example, Sweden"s Volvo has developed a breathalyzer attached to a car"s seat belt that drivers must blow into before the engine will start. Nissan"s new concept vehicle also includes a dashboard-mounted camera that tracks a drivers alertness by monitoring their eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest. The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology. "For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015. The car"s seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it"s going to register, so we need to study what"s the appropriate level for the system to activate," he says. In the UK, some research groups are using similar advanced techniques to understand driver behavior and the effectiveness of different road designs.
