People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem. First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle. Next the thinker must define the problem. Before Sam can repair his bicycle, he must find out the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific. Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully. After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels. Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels. Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. he has solved the problem. Which of the following is    _    ? A) People do not analyze the problem they meet. B) People often accept the opinions or ideas of other people. C) People may learn from their past experience. D) People can not solve some problems they meet.

Have you lost your marbles  ? Don't worry! You can buy more from Harli Jordean.   Harli Jordean, the 8-year-old kid, soon to be 9, is just too lovely. He was born in Stoke Newington, London in spring 2003. He started up an Internet marble company where he sells the toys. And recently the 8-year-old student was written into the record books for being the youngest founder and chief executive officer   (CEO) of an Internet company.   Harli's love for marbles got rolling when he was 6. According to Tina, Harli's mother, he loved the colcorful toys so much that he would go to sleep talking about marbles and the first thing in the morning he did was talking about marbles. And his family started calling him "the Marble King".   "I like the patterns   and designs of marbles. You can collect hundreds of different color1s, shaps, and sizes. It's fun," Harli told WR News. "And I really enjoy looking at them, touching them, holding them, studying them and playing them with my friends."   Harli Jordean's marble company has a long history. After losing his marbles to an older boy, Harli and his mom turned to the Internet for ordering more marbles. However, they couldn't find a Web site that sold the toys. That gave Harli an idea-to start a Web site where people could find different types of marbles. With his family's help, Harli created a Web site that sells marbles and marble accessories. His collection includes tiny and large marbles, along with clear and color1ful ones.   Since starting his business, Harli has learned how to work with marble suppliers and fill orders. In the past two years, he's received orders from customers around the world. Some of the countries where he has sold the most marbles are Brazil, Italy, and the United States.

Babies who watch TV are more likely to show late learning development and language at 14 months, especially if they are watching programs aimed at adults and older children, according to a new study, which would probably surprise those parents who leave their babies in front of a TV set. Babies who watched 60 minutes of TV daily had developmental scores a third lower at 14 months than babies who were watching less TV. Although their developmental scores were still in the normal range, the difference may have been due to the fact that when children and parents are watching TV, they are missing the talking, playing and other communications that are important to learning and development. This new study, which appeared in the Aechives of Pediatric and Adolescent Medicine, followed 259 lower-income families in New York, most of whom spoke Spanish as their primary language at home. Other studies of higher-income families have also come to the same conclusion: TV watching is not only non-educational, but it seems to slow down babies' development. But what about "good" TV, like Sesame Street? The researchers didn't find any difference when compared to non-educational programs designed for small children, like Spongebob SquarePants. Earlier research by some of the same scientists, most of whom are at New York University School of Medicine's Bellevue Hospital Centre, has found that parents whose children watch non-educational TV programs like Spongebob SquarePants spend less time reading to their children or teaching them. At this point, parents reading this will probably be astonished. TV is so often a parent's good friend, keeping children happily occupied so that the adults can cook dinner, answer the phone, or take a shower. But, clearly, this electronic babysitter is not an educational aid. It is best to make sure the babies are fast asleep if you have to watch TV. We can infer from the passage that  _  . A) Educational and non-educational TV have different effects on babies B) Many parents leave babies to the TV to do their own things C) Educational TV is very popular among higher-income families D) Lower-income families tend to teach their babies at home
