With the price of a small home computer now being lower, experts predict that before long all schools and businesses and most families in the rich part of the world will own a computer of some kind. Among the general public, computers arouse strong feelings people either love them or hate them.The computer lovers talk about how useful computers can be in business, in education and in the home apart from all the games, you can do your accounts on them, use them to control your central heating, and in some places even do your shopping with them. Computers, they say, will also bring some leisure, as more and more unpleasant jobs are taken over by computerized robots.The haters, on the other hand， argue that computers bring not leisure but unemployment. They worry, too, that people who spend all their time talking to computers will forget how to talk to each other. And anyway, they ask, whats wrong with going shopping and learning languages in classroom with real teachers? But their biggest fear is that computers may eventually take over human beings altogether.Questions 32 to 35 are based on the passage you have just heard.32. What does this passage mainly talk about? 答案: C33. According to the passage, what is not mentioned about computers? 答案:A34. What is the biggest fear of the computer haters? 答案:D35.

First of all, they have greatly improved material well-being in several areas of life. In the field of medicine, cures for life threatening diseases have enabled people to live longer. In communication the telephone and e-mail have made it possible for us to communicate with anyone in the world without leaving our homes or offices. Advances in transportation allow businessmen to fly across the ocean in the morning and return home the same evening. Space technology has put men on the moon. More efficient ways of using available resources, such as coal and solar power, have been explored. Scientific discoveries have also changed mans moral atmosphere. Ethical issues are raised by these discoveries. Should we keep a terminally ill person alive through drugs and machines or should we allow him to die in dignity? With advances in transportation has come the problem of pollution for nearly every major city in the world. If cities become uninhabitable, then such technical advances may come with too great a price to pay. Many people also question the wisdom of sending men to the moon when there are urgent problems that have not been solved on earth. During future years, increasing attention must be given to the moral as well as the practical applications of science.1 What have scientific discoveries made according to the passage?_S/6.A.

A new study says “Yes”. According to a survey of 35,000 people around the world, access to communications technology is a major factor in increasing happiness.We all need a few basic things in order to be happy: access to clean water and food, a home, health care, and relationships. But once the necessities are met, what do people most desire? The answer is access to communication devices, according to the survey by BCS, the Chartered Institute for IT.Most people in the study gave similar answers, but the potential happiness increase that technology could bring about was particularly great in women and in people with low incomes or levels of education even in developing countries.While farmers in the African countryside arent likely to pick up the latest shiny toys from Apple, even a simple cell phone can serve as a valuable happiness-increasing tool, allowing the development of social networks beyond the community.“Whether young or old, were all social beings, we all have a need for communication,” researcher Paul Flatters told BBC News.In rural (乡村) communities, access to communications technology such as cell phones and computers is limited, but expanding, thanks to groups like One Laptop Per Child, which supplies children in developing countries with basic laptops that allow them to research school projects and connect with others all over the world. Other groups, like the UK s Computer Aid, are helping rural villagers get wired with the help of portable cyber cafes (便携式网吧) that allow locals to log online to send emails and perform work-related research.And back home, it seems from the results that small IT devices like the iPhone really can increase your happinessprovided you use it to talk with and send messages, photos, and videos to friends and family to help strengthen your social networks, rather than simply play Angry Birds.6.How does an iPhone make one happier, according to the study?_S/6.A By giving one a higher income.

What does the study show us?_S/6.A How many people are using iPhones. B What communication tools people like to use.C What people need besides the basic necessities.D What is the life of people in developing countries like.8. Why technology can increase happiness particularly in women and in people with low inco
