Drunken driving -sometimes called America's socially accepted form of murder--has become a national epidemic  . Every hour of every day about three Americans on average are killed by drunken drivers,adding up to an incredible 250,000 over the past ten years. A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were in most courts,but the drunken killing has recently caused so many well-publicized tragedies,especially concerning young children,that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21,reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18,the number of people killed by 18-20 years old drivers more than doubled,so the state recently upped it back to 21. Reformers,however,fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop 'responsible attitudes' about drinking and teach them to resist peer pressure to drink. Though new laws have led to increased arrests and tests in many areas already,to a marked drop in accidents,some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who was 'obviously drunk' and later drove off the road,killing a 9-year-old boy. As the accidents continue to occur daily in every state,some Americans are even beginning to speak well of the 13 years national prohibition of alcohol that began in 1919,which President Hoover called the 'noble experiment'. They forgot that legal prohibition didn't stop drinking,but encouraged political corruption and organized crime. As with the booming drug trade generally,there is no easy solution. Which of the following best shows the writer's opinion of drunken driving? A) It may lead to organized crime. B) It is difficult to solve this problem. C) The new laws can stop heavy drinking. D) There should be no bars to serve drinks.

Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the robot mail carrier, brings mail to a large office building in Washington, D.C. He is one of 250 robot mail carriers in the United States. Mr. Leachim, who weights two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child's name, their parents' names, and what each child knows and needs to know. In addition, he knows each child's pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification   number. His computer brain puts the child's voice and number together. He identifies the child with no mistakes. Another advantage is that Mr. Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr. Leachim's lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off. What is the most important thing Mr. Leachim can do in his lessons? A) To meet the needs of each student. B) To talk to the students in different languages. C) To keep everyone's interest in his lessons. D) To introduce more hobbies to the children.

Like many new graduates, I left university full of hope for the future but with no real idea of what I wanted to do. My degree, with honors, in English literature had not really prepared me for anything practical. I knew I wanted to make a difference in the world somehow, but I had no idea how to do that. That's when I learned about the Lighthouse Project. I started my journey as a Lighthouse Project volunteer by reading as much as I could about the experiences of previous volunteers. I knew it would be a lot of hard work, and that I would be away from my family and friends for a very long time. In short, I did not take my decision to apply for the Lighthouse Project lightly. Neither did my family. Eventually, however, I won the support of my family, and I sent in all the paperwork needed for the application. After countless interviews and presentations, I managed to stand out among the candidates and survive the test alone. Several months later, I finally received a call asking me to report for the duty. I would be going to a small village near Abuja, Nigeria. Where? What? Nigeria? I had no idea. But I was about to find out. After completing my training, I was sent to the village that was small and desperately in need of proper accommodation. Though the local villagers were poor, they offered their homes, hearts, and food as if I were their own family. I was asked to lead a small team of local people in building a new schoolhouse. For the next year or so, I taught in that same schoolhouse. But I sometimes think I learned more from my students than they did from me. Sometime during that period, I realized that all those things that had seemed so strange or unusual to me no longer did, though I did not get anywhere with the local language, and returned to the United States a different man. The Lighthouse Project had changed my life forever. On arrival at the village, the author was  _ A) asked to lead a farming team B) sent to teach in a schoolhouse C) received warmly by local villagers D) arranged to live in a separate house.

We often think of future. We often wonder what the world would be like in a hundred years'time. Think of space,perhaps a permanent  station on the moon will have been set up. Perhaps people will be able to visit the moon as tourists. Cheap rockets for space travel will have been developed,permitting long journeys throughout the solar system . When that time comes,people will be taking holidays in space and visiting other planets. Great progress will have been made in medicine,too. Perhaps a cure will have been discovered for the most terrible of all diseases--cancer. Pollution is a problem we must solve. In a hundred years'time it will have been controlled. All the world will have been developed -- even Antarctica. There will be large cities in Antarctica. We already have supersonic  flight,but in a hundred years'time we will have supersonic land travel as well. We will have used up most of earth's land to build our cities, so floating cities will have been built. The Japanese already have plans for cities of this kind. And there will be cities under the sea. The first of these will have been completed. Man will also have supersonic land travel   _  . A) in a year B) about half a century later C) in the year 2050 D) about a century later
