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. "It really ...surprised me and probably ... my teachers too. I don't think they believed me when I used... What can be the best title of the passage? A) People can buy marbles on Internet. B) How to start a Web site selling marbles? C) A kid became the youngest founder and CEO. D) Why do kids like marbles?

Our brains work in complex and strange ways. There are some people who can calculate the day of the week for any given date in 40,000 years, but who cannot add two plus two. Others can perform complex classical piano pieces after hearing them once, but they cannot read or write. Dr. J. Langdon Down first described this condition in 1887. He called these people idiot savants. An idiot savant is a person who has significant mental injury, such as in autism   or retardation. At the same time, the person also exhibits some extraordinary skills, which are unusual for most people. The skills of the savant may vary from being exceptionally gifted in music or in mathematics, or having a photographic memory. One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr. Benjamin Rush, an American doctor. His patient, Thomas Fuller, was brought to Virginia as a slave in 1724. It took Thomas only 90 seconds to work out that a man who has lived 70 years, 17 days, and 12 hours has lived 2,210,500,800 seconds. Despite this ability, he died in 1790 without ever learning to read or write. Another idiot savant slave became famous as a pianist in the 1860s. Blind Tom had a vocabulary of only 100 words, but he played 5,000 musical pieces beautifully. In the excellent movie Rain Man, made in 1988 and available on video cassette, Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise, with his ability to perform complex calculations very rapidly. Today we more clearly recognize that the idiot savant is special because of brain impairment. Yet not all brain injury leads to savant skills. Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills. However few people wish to participate in such experiments. There are many excellent reasons for not undergoing unnecessary experimentation on one's brain. The term idiot savant is outdated and inappropriate. Virtually all savants have a high degree of... What can you infer from the passage? A) Idiot savants have real talents for art and math. B) Dr. Down is the first person who found idiot savants. C) Few people wish to risk becoming savants by brain operations. D) Intentional left brain impairments will surely lead to idiot savants.

Zoo elephants don't live as long as those in the wild, according to a study sure to cause debate about keeping the giant animals on display. Researchers compared the life spans of elephants in European zoos with those living in Amboseli National Park in Kenya and others working on a timber enterprise in Buma. Animals in the wild or in natural working conditions had life expectancies twice than or more of their relatives in zoos. Animal care activists have urged in recent years to discourage keeping elephants in zoos, largely because of the lack of space and small numbers of animals that can be kept in a group. The researchers found that the _ life span for African elephants in European zoos was 16.9 years, compared with 56 years for elephants who died of natural causes in Kenya's Amboseli Park. Adding in those elephants killed by people in Africa lowered the median life expectancy there to 35.9 years. For the more endangered Asian elephants, the median life span in European zoos was 18.9 years, compared with 41.7 years for those working in the Burma Timber Enterprise. Median means half died younger than that age and half lived longer. There is some good news, though. The life expectancies of zoo elephants have improved in recent years, suggesting an improvement in their care and raising, but "Protecting elephants in Africa and Asia is far more successful than protecting them in Western zoos." There are about 1,200 elephants in zoos, half in Europe, researchers concentrated on female elephants, which make up 80 percent of the zoo population. One amazing thing was that Asian elephants born in zoos had shorter life spans that those brought to the zoos from the wild. Zoos usually lack large areas that elephants are used to in the wild, and that zoo animals often are alone or with one or two other unrelated animals, while in the wild they tend to live in related groups of 8 to 12 animals. In Asian elephants, baby death rates are two to three times higher in zoos than in the Burmese logging camps, and then, in... Which of the following is Not the disadvantage of keeping elephants in zoos? A) Limited number of relatives. B) Lack of space. C) Shorter life expectancy. D) Less attention.
