单选题 You really have to get very old before you realize you're old. I'm in my middle fifties and I don't feel 21 yet.

单选题 Sometimes children are kidnapped. Kidnapping is like stealing a child. It is important that kidnapped children are found and brought home as soon as possible. The sooner the public knows about a kidnapping the sooner they might be able to help. Some people decided to start a program that would alert the public about kidnappings right away. This program is called Care Alert. The Care Alert program gives television and radio stations important information about a recently kidnapped child. These stations will then tell the public what happened in hopes that someone might be able to help. Anyone that may have seen something about the kidnapping could then call the police. Sometimes one parent of a child kidnaps his or her own child. These kidnappings are not usually used in the Care Alert program. The Care Alert program is only used when a stranger has taken a child. When a child is kidnapped he is in a lot of danger. It is very important to find him as soon as possible. It is hoped that this new Care Alert program will save children's lives.

单选题 Until the 1980s, the American homeless population is mainly made up of older males. Today, homelessness strikes much younger part of society. In fact, a 25-city survey by the U.S. Conference of Mayors in 1987 found that families with children make up the fastest growing part of the homeless population. Many homeless children gather in inner cities; this transient (变化无常的) and frequently frightened student population creates additional problems—both legal and educational—for already overburdened urban school administrators and teachers. Estimates of the number of homeless, Americans range from 350, 000 to three million. Like-wise, estimates of the number of homeless school children vary radically. A U.S. Department of Education report, based on state estimates, states that there are 220,000 homeless school-age children, about a third of whom do not attend school on a regular basis. But the National Coalition for the Homeless estimates that there are at least two times as many homeless children, and that less than half of them attend school regularly. One part of the homeless population that is particularly difficult to count consists of the 'throwaway' youths who have been cast of their homes. The Elementary School Center in New York City estimates that there are 1.5 million of them, many of whom are not treated as children because they do not stay in family shelters and tend to live by themselves on the streets. Federal law, the Stewart B. McKinney Homeless Assistance Act of 1987, includes a section that addresses the educational needs of homeless children. The educational provisions (规定) of the McKinney Act are based on the belief that all homeless children have the right to a free, appropriate education.

单选题 In the US, people prefer waiting for a table to sitting with people they don't know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don't know, it is impolite to light up a cigarette without first asking if it will disturb them. At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill. Most cities and towns have no rules about opening and closing times for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day. Servings in restaurants are often large, too large for many people. If you can't finish your meal but would like to enjoy the food later, ask your waitress or waiter for a 'doggie bag'. It may have a picture of a dog on it, but everybody knows you are taking food for yourself. Supper and dinner are both words for the evening meal. Some people have 'Sunday dinner'. This is an especially big noon meal. Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change.

单选题 I am ______ of the same old breakfast every morning,

单选题 Please keep an eye on my luggage, and I'll be back______.

单选题 Men have traveled ever since they first appeared on the earth. In primitive times they did not travel for pleasure but to find new places where their herds could feed, or to escape from hostile neighbors, or to find more favorable climates. They traveled on foot. Their journeys were long, tiring, and often dangerous. They protected themselves with simple weapons, such as wooden sticks or stone clubs, and by lighting fires at night and, above all, by keeping together. Being intelligent and creative, they soon discovered easier ways of traveling. They rode on the backs of their domesticated animals; they hollowed out tree trunks and, by using bits of wood as paddles, were able to travel across water. Later they traveled, not from necessity, but for the joy and excitement of seeing and experiencing new things. This is still the main reason why we travel today. Traveling, of course, has now become a highly organized business. There are cars and splendid roads, express trains, huge ships and jet airliners, all of which provide us with comforts and security. This sounds wonderful. But there are difficulties. If you want to go abroad, you need a passport and a visa, ticket, luggage, and a hundred of other things. If you lose any of them, your journey may be ruined.

单选题 I ______ to the meeting on time, but I had a flat tire on the way.

单选题 As my train wasn't due to leave for another hour, I had plenty of time to spare. After buying some newspapers to read on the journey, I made my way to the luggage office to collect the heavy suitcase I had left there three clays before. There were only a few people waiting, and I took out my wallet to find the receipt for my case. The receipt didn't seem to be where I had left it. I emptied the contents of the wallet, and railway-tickets, money, scraps of paper, and photographs fell out of it; but no matter how hard I searched, the receipt was nowhere to be found. looked at me suspiciously as if to say that he had heard this type of story many times and asked me to describe the ease. I told him that it was an old, brown-looking object, no different from the many eases I could see on the shelves. The assistant then gave me a form and told me to make a list of the chief contents of the ease. If they were correct, he said, I could take the ease away. I tried to remember all the articles I had hurriedly packed and wrote them down as they came to me. After I had done this, I went to look among the shelves. There were hundreds of cases there and for one dreadful moment, it occurred to me that if someone had picked the receipt up, he could have easily claimed the case already. This hadn't happened fortunately, for after a time I found the ease lying on its side high up in a corner. After examining the articles inside, the assistant was soon satisfied that it was mine and told me I could take the ease away. Again I took out my wallet: this time to pay. I pulled out ten-shilling note and the 'lost' receipt slipped out with it. I couldn't help blushing and looked up at the assistant. He was nodding his head knowingly, as if to say that he had often seen this happen before too!

单选题 At the first sight the planet Mars does not appear very welcome to any kind of life. It has very little oxygen and water, the temperature at night is below -50~Cand winds of 100 miles per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it some time in the past, and it is believed that there is enough ice at the poles to cover the planet with water if it melts. Although there is no life on the Mars now, some scientists think that there may have been some form of life long time ago. At that time, the planet had active volcanoes; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists. Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere. With warmth, water and carbon dioxide (二氧化碳), simple plants could begin to grow. These plants could slowly make the Mars more suitable for living. It is estimated that the whole process might take between 100,000 and 200,000 years. In the meantime, people could begin to live on the planet in special closed environments. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
