A. careful B. curious C. interested D. sure C Creativity is the key to a brighter future, say education and business experts. Here is how schools and parents can encourage this important skill in children. If Dick Drew had listened to his boss in 1925, we might not have a product that we now think of as of great importance: a new type of tape. Drew worked for the Minnesota Mining company. At work he developed a kind of material strong enough to hold things together. But his boss told him not to think more about the idea. Finally, using his own time, Drew improved the tape, which now is used everywhere by many people. And his former company learned from its mistake. Now it encourages people to spend 15 percent of their work time just thinking about and developing new ideas. Creativity is not something one is just born with, nor is it necessarily a character of high intelligence. The fact that a person is highly intelligent does not mean that he uses it creatively. Creativity is the matter of using the resources one has to produce new ideas that are good for something. Unfortunately, schools have not tried to encourage creativity. With strong attention to test results and the development of reading, writing and mathematical skills, many educators give up creativity for correct answers. The result is that children can give back information but cannot recognize ways to use it in new situations. They may know the rules correctly, but they are unable to use them to work out practical problems. It is important to give children choices. From the earliest age, children should be allowed to make decisions and understand their results. Even if it’s choosing between two food items for lunch, decision-making helps thinking skills. As children grow older, parents should let their children decide how to use their time or spend their money, but not help them too much if they make the wrong decision. The child may have a hard time, but that is all right. This is because the most important character of creative people is a very strong desire to find a way out of trouble. 71. What did the company where Drew once worked learn from its mistake? . A. They encouraged people to work a longer time B. They discouraged people to think freely C. They asked people to spend all their work time developing new ideas D. They encouraged people to spend some of their work time considering and improving new ideas 72. Creativity is something . A. that people are born with B. that depends on intelligence C. that is a way of using what one has learned to work out new problems D. that is not important at all 73. Why don’t schools try to encourage creativity? A. They don’t understand the importance of education. B. They don’t want their students to make mistakes. C. They pay too much attention to examination marks, language and mathematical skills. D. They think it more important to remember some information. 74. What should the parents do when their children decide how to spend their money? A. Try to help them as much as possible. B. Take no notice of whatever they do. C. Help them if their decision is wrong but not too much. D. Leave them as they are. 75. This passage mainly deals with the question “ . A. What is the key to a brighter future B. What creativity is C. How schools and parents can encourage creativity in children D. Whether schools and parents should allow children to make choices and decisions 版权所有 【查看更多】

    　　Computer users are being warned by industry experts to pay attention to secret codes which could be used to record their conversations.

    　　E-mail, screensavers, and electronic greeting cards can carry a secret code which is able to turn on the computer's micro-phone, make a recording, and forward it to someone else without the user's knowledge.

    　　In fact any attachments(附件) sent to a computer, whether it is a game of Space Invaders, or a moving picture, can possibly be used to spy.

    　　Experts say people should always think twice about opening attachments because—although rat common—bugging(窃听) by computer can, and has been done.

    　　Bill Lyons, head of the Internet Security Company Finjian, said, “People in the army have tested this and you can be sure, if people in general are aware of(知道) it, then computer hackers are aware of it.
