Scientific experiments can sometimes go wrong and when they do the results may range from the disastrous to the troubling. One such experiment took place in South America about fifty years ago. Whether its final consequences will cause serious damage or nothing more than a small trouble still remains to be seen. The story began in 1956 when an American scientist working in Brazil decided to solve the problem of increasing the productivity of that country's bees. He imported a very active type of African bee from Tanzania and mated it with the more easy-going native variety to produce a new kind of bees. The new bees worked harder and produced twice as much honey. It seemed that Professor Kerr, for that was the scientist's name, had a total success on his hands.www.zxxk.com Then things began to go wrong. For some reason as yet unseen, but perhaps as a result of something in their environment, the new bees began to develop extremely attacking personalities. They became bad-tempered and easy to be angry, attacked the native bees and drove them from their living places. But worse was to follow. Having taken over the countryside, the new bees, with their dangerous stings , began to attack its neighbors -- cats, dogs, horses, chickens and finally man himself. A long period of terror began that has so far killed a great number of animals and about 150 human beings. This would have been bad enough if the bees had stayed in Brazil. But now they are on the move, heading northwards in countless millions towards Central and North America, and moving at the alarming speed of 200 miles a year. The countries that lie in their path are naturally worried because it looks as if nothing can be done to stop them. Which of the following may be the cause of the new bees' attacking personalities? A) Their production of honey. B) Their living environment. C) Their hard work. D) Their bad temper.

Ques: Traditional Japanese food is surely one of the healthiest and most delicious in the world, and _ , foods like tofu, sushi and even green tea are now familiar and can be found easily out of Japan. As a national cuisine , thanks to many social as well as political changes, Japanese food has greatly developed over the past few centuries. In ancient times, when much of the traditional cuisine was influenced by Korean and Chinese cultures, Japanese cuisine slowly changed with the start of the medieval period, which brought along with it new tastes. With the coming of the modern age, a great many changes took place and the Japanese cuisine was influenced greatly by Western culture. However, the traditional Japanese food of today is still very like what existed toward the end of the 19th century. This would mean that a large part of the Japanese cuisine includes those foods whose cooking methods and ingredients have been introduced from other cultures, but which have since then been experimented with and developed by the Japanese themselves. The thing about Japanese food is that you either will love it or will completely look down upon it. With traditional Japanese food, there is no such thing as an in-between. However, chances are that if you hate Japanese food, then you probably haven't even tasted real Japanese food or you simply haven't given yourself the chance to like it. Unlike other cuisines, Japanese food is not something that you will appreciate after having only a bite. Like wines and cigars, Japanese food needs time to be liked. What does the writer mean by saying "fortunately for most of us"? A) That most people know how to prepare tofu and sushi themselves. B) That most traditional Japanese food can be enjoyed everywhere. C) That we can enjoy some traditional Japanese food out of Japan. D) That Japanese food like tofu, sushi and even green tea is not strange to us.

A new age is coming.Call it what you will: the service economy, the information age, the knowledge society.It all translates to a fundamental change in the way we work.Already we're partly there, the percentage of people who earn their living by making things has fallen dramatically in the Western World.Today the majority of jobs in America, Europe and Japan are in the service industry, and the number is on the rise.More women are in the work force than ever before.There are more part-time jobs.More people are self-employed.But the range of the economic transformation can't be measured by numbers alone, because it also is giving rise to important new way of thinking about the nature of work itself.Long-held ideas about jobs and careers, the skills needed to succeed, even the relation between individuals and employers - all these are being challenged. We have only to look behind us to get some sense of what may lie ahead.No one looking ahead 20 years possibly could have foreseen the ways in which a single invention, the chip , would transform our world thanks to its applications in personal computers, digital communications and factory robots.Tomorrow's achievements in biotechnology, artificial intelligence or even some still unimagined technology could produce a similar wave of dramatic changes.But one thing is certain: information and knowledge will become even more valid, and the people who possess it, whether they work in manufacturing or services, will have the advantage and produce the wealth.Computer knowledge will become as basic a requirement as the ability to read and write.The ability to solve problems by applying information instead of performing routine tasks will be valued above all else.If you cast your mind ahead 10 years, information service will be superior.It will be the way you do your job. A characteristic of the new age mentioned in the passage is that _ . A) the service industry mainly relies on females B) manufacturing industries are steadily increasing C) more people are in the service industry than before D) the work in the service industry is more comfortable than that in manufacturing industry
