单选题 Deep inside a mountain near Sweetwater in East Tennessee is a body of water known as the Lost Sea. It is listed by the Guinness Book of World Records as the world's largest underground lake. The Lost Sea is part of an extensive and historic cave system called Craighead Caverns. The caverns have been known and used since the days of the Cherokee Indian nation. The cave expands into a series of huge rooms from a small opening on the side of the mountain. Approximately one mile from the entrance, in a room called 'The Council Room', many Indian artifacts have been found. Some of the items discovered include pottery, arrowheads, weapons, and jewelry. For many years there were persistent rumors of a large underground lake somewhere in a cave, but it was not discovered until 1905. In that year, a thirteen-year-old boy named Ben Sands crawled through a small opening three hundred feet underground. He found himself in a large cave half filled with water. Today tourists visit the Lost Sea and ride far out onto it in glass-bottomed boats powered by electric motors. More than thirteen acres of water have been mapped out so far and still no end to the lake has been found. Even though teams of divers have tried to explore the Lost Sea, the full extent of it is still unknown.

单选题 'When one of the doctors criticizes(批评) me, I get defensive: I feel like a child again, being scolded, and I want to explain that I' m not wrong. ' says Viola, a nurse. This is a common reaction(反 应) to criticism, but not a good one. There are better ways of dealing with criticism. 1. Try to be objective (客观). When Sol was criticized by his new employer for not having made a sale, Sol's reaction was to feel sorry for himself. 'I had put everything I had into making that sale,' Sol says,' and I felt that I had failed as a person. I had to learn through experience not to react like that to each failure. ' 2. Take time to cool down. Rather than reacting immediately to criticism, take some time to think over what was said. Your first question should be whether the criticism is fair from the other person' s position. The problem may be a simple misunderstanding of what you did or your reasons for doing it. 3. Take positive(积极的) action. After you cool down, consider what you can do about the situation. The best answer may be 'nothing'. 'I finally realized that my boss was having personal problems, and taking them out on me because I was there,' says Sheila. 'His criticisms didn't really have anything to do with my work, so nothing I said or did was going to change them. ' In Sheila' s case, the best way to deal with it was to leave her job. However, that' s an extreme reaction. You may simply explain your opinion without expecting an in-depth discussion. You may even decide that the battle isn' t worth fighting this time. The key, in any case, is to have a reasonable plan.

单选题 Banks are not ordinarily prepared to pay out all accounts; they rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced. One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived. The other banks expected a run the next day, and so the officers of the bank in which Mrs. Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand. The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers' windows. The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs. Vaught says that she had difficulty keeping herself from doing the same.

单选题 People joke that no one in Los Angeles reads; everyone watches TV, rents videos, or goes to the movies. The most popular reading material is comic books, movie magazines, and TV guides. City libraries have only 10 percent of the traffic that car washes have. But how do you explain this? An annual book festival in west Los Angeles is flourishing year after year. People wait haft an hour for a parking space to become available. This outdoor festival, sponsored by a newspaper, occurs every April for one weekend. This year's attendance was estimated at 70,000 on Saturday and 75,000 on Sunday. The festival consisted of 280 exhibitors. There were about 90 talks given by authors, with an audience question-and-answer period following each talk. Autograph(亲笔签名)seekers sought out more than 150 authors. A food court sold all kinds of popular food and diverse foreign foods, from American hamburgers to Hawaiian shave ice drinks. Except for a $ 7 parking fee, the festival was free. Even so, some people avoided the food court prices by staying away and having their own sandwiches and drinks. People came from all over California. One couple drove down from San Francisco. 'This is our sixth year here now. We love it, 'said the husband. 'It's just fantastic to be in the great outdoors, to be among so many books and authors, and to get some very good deals, too.' The idea for the festival occurred years ago, but nobody knew if it would succeed. Although book festivals were already popular in other US cities, would Los Angeles residents welcome one? 'The citizens of the city are very unpredictable, 'said one of the festival founders.
