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. Most kids just love marbls! So how does Harli feel about being the world's youngest CEO? "It feels marvelous . I like having my own company. I like being the boss," he says.

British and American scientists are raising genetically modified pigs in the hope of providing organs for transplant to humans, the project leader wrote in a newspaper Sunday. Scientists in London and California have begun conducting the genetic experiments to find a solution to record-long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times. In Britain alone, around 8,000 patients are waiting for a transplant. "People needing a new heart or liver are waiting for someone else to die -usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans." The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital. Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets , adding them to the animal's sperm . He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate. The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri. "Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote. Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs. It can be inferred from the passage that _ . A) animal organs are commonly used for human transplant now B) lots of patients need animal organ transplants now C) examples of the animal tissues being rejected have happened D) it is not safe to use animal organs for human transplant

Q: Empathy lets us feel another person's pain and drives us to help. Do any other animals feel empathy? Scientists recently found that rats do, too. Most people don't like rats. In many people's eyes, rats are only bad. But Jean Decety and his partners at the University of Chicago did an experiment. It showed that rats are kind, warm-hearted animals. They can feel each other's pain. Scientists placed pairs of rats in plastic cages for two weeks. During this time they got to know each other. Then they put one of the rats from each pair into a small container in the cages. The small container had a door. It was so designed as to fall to the side when the free rat touched it. Many of the trapped rats squeaked to show their discomfort. The other rats of the pairs could see their suffering friends clearly. In most pairs, the free rats would become very worried about their friends. They kept trying to save their friends again and again throughout the month. Scientists put the rats' favorite chocolate in the cages, but the rats didn't eat it until they had saved their friends successfully. Scientists also found that female rats seemed to act more empathetic than male rats. "The results are the first to show that rats take action in response to another's trouble," Decety said. "Monkeys and chimpanzees have similar behavior. But unlike those animals, rats can be ready used in laboratory studies. They will help us to learn which parts of the brain lead to empathy and helping behavior and whether empathy is natural." Which of the following animals were NOT mentioned in the passage? A) Monkeys. B) Chimpanzees. C) Rats. D) Cats.
A: D

Zheng Pengyu: Interest is the best teacher. Classrooms that weren't fixed could give students the chance to explore their interests. At the same time, they would be able to learn on their own because they would have to make their own decisions. All in all, the new system would be a good chance to inspire students' passion for studying. Sun Yao: Despite its benefits, I'm worried about whether the new system would work. Going to different classrooms would take up a big part of our break time and we would have less time to relax after class. Also, not all schools could offer so many diversified classes. Shi Zhenghan: I support students learning in different classes. It would solve the problem of some students thinking the classes are too easy while some think they are too difficult. Teachers could also teach more effectively. What's more, friendships built while in different classes might be a pleasant surprise. Zhou Qingqing: In my opinion, studying in different classrooms might affect students' psychological development. They might find it difficult to develop deep and strong friendships with other students if they had to change classrooms constantly. They would also lose their sense of belonging to a certain class. Hu Qile: I _ the idea. It would help teachers set up special teaching plans for different classes. For students, making choices by themselves could encourage them to be responsible. Changing classrooms could also help relive the boredom of doing the same dull routine every day. Wang Xiaoqian: The new system might help with students' individual development, but I still prefer the current system. Studying in one fixed classroom, students with different academic levels can help each other. Spending your senior middle school years with the same classmates is an unforgettable experience. What is the passage about? A) Schools should offer diversified classes to students. B) Students find it difficult to develop friendship. C) Different opinions about changing classroom. D) Changing classroom can help with students' individual development.
