The forest in Senegal, a country in western Africa, is full of the chimps' usual noises. Suddenly dogs bark. Larger male chimps drop from the trees to face the threat while the others climb to safety. Then the dogs' young human masters appear.

One mother chimp with a tiny baby tries to run. The dogs attack and separate them. The two teenage boys quickly catch the baby chimp. But they don't act out of sympathy — they save the baby so they can sell it.

    After the teenagers return to their hometown, they visit a man who is said to be very interested in chimps. When they ask the man, Johnny Kante, if he wants to buy the baby, he replies, “That's not what we do.” Kante is a member of a scientific team. Although Kante is angry with the teens for capturing the chimp, he hides his anger and persuades them to take him to the baby chimp.

    Unsure of what to do next upon seeing the chimp, Kante calls Jill Pruetz, the head of the chimp research team. “I'm really worried,” says Pruetz, doubtful that the mother is still alive. But knowing that wild chimps sometimes adopt orphans（孤儿）， Kante and pruetz decide they must try to return the baby chimp to its wild community.

    Kante pays another visit to the teenagers. After he explains how much trouble they are in, because chimps are an endangered species, he requests they should give him the frightened baby without payment. They agree. Kante takes the baby chimp to his home and feeds her milk from a bottle whenever she cries.

    The next morning, Pruetz and Kante leave the baby with another team member and begin their search for the wild chimps. Pruetz quickly finds the group in the woods. She recognizes the female that is without her child.

    Pruetz is so excited that she runs the entire mile back to bring the baby chimp to the tree where the chimps are hanging out. The researchers place the baby on the ground near the tree and back away. Almost immediately, a male chimp drops to the ground and stares at the baby curiously. He carries her back to where the mother is waiting.

    Pruetz still can't believe how fortunate they were to have reunited the mother and child. “Surprising is the only word I can think of,” she says.

    He is quiet and shy. He likes to hide(隐藏) his eyes behind his hair. He doesn't smile very often. However, if you talk to him about music, he'll have a lot to say.

    This is Jay Chou, the 24-year-old Taiwanese pop king(天王). His fans are so excited because he will sing songs in Beijing on September 12. Those songs are from his new album (唱片), “Ye Huimei”, and the album was released (发行) in July and was named after his mother.

    Chou grew up just with his mother. He did not talk much and did badly in many school subjects.

    His mother noticed the boy's special interest in music and sent him to learn piano when he was only three years old. He loved it and kept on practicing.

    Chou is not very handsome. He does not speak clearly when he sings or talks. But the singer has huge crowds of fans. “He is really good at music. It makes him attractive(有魅力的) to me,” said Liu Jiajun, a Junior 2 student in No.101 Middle School in Beijing.

    “He is true to himself. He never follows others,” said Zhang Yujie, a Junior 1 girl at Huaibei Middle School in Sihong, Jiangsu Province.

    Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.

    Sounds unusual, doesn't it? But it's not that unrealistic, with the development of China's high-speed railway system. And that's not all. China has an even greater high-speed railway plan to connect the country with Southeast Asia, and eventually Eastern Europe. China is negotiating to extend its own high-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore.

    China has proposed three such projects. The first would possibly connect Kunming with Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe. The new system would still follow China's high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes. Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge(轨距), maintenance of railway tracks. But the key issue is really money. China is already spending hundreds of billions of yuan on domestic railway expansion.

    China prefers that the other countries pay in natural resources rather than with capital investment. Resources from those countries could stream into China to sustain development. It'll be a win-win project. For other countries, the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.

    For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China's far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they'll trade with Central Asian and Eastern European countries.

    Is Paperless Office Really Paperless?

    A rising economy increased paper sales by 6 to 7 percent each year in the early to mid-1990s, and the convenience of desktop printing allowed office workers to indulge anything and everything. In 2004, Ms. Dunn, a communications supplies director, said that plain white office paper would see less than a 4 percent growth rate, a primary reason for which is that some 47 percent of the workforce entered the job market after computers had already been introduced to offices.

    For office innovators, the dream of paperless office is an example of high-tech arrogance（傲慢）. Today's office service is overwhelmed By more newspapers than ever before. After decades of development, the American government can finally get rid of the madness on paper. In the past, the demand for paper has been far ahead of growth in the American economy, but the sales have slowed markedly over the past two to three years, despite the good economic conditions.

    “Old habits are hard to break,” says Ms. Dunn. “There are some functions that paper serves where a screen display doesn't work. Those functions are both its strength and its weakness.” Analysts attribute the decline to such factors as advances in digital databases and communication systems. Escaping our craving for paper, however, will be anything but an easy affair.

    “We're finally seeing a reduction in the amount of paper being used per worker in the workplace,” says John Maine, vice president of a paper economic consulting firm. “More information is being transmitted electronically, and an increasing number of people are satisfied that information exists only in electronic form without printing multiple backups.”

    To reduce paper use, some companies are working to combine digital and paper capabilities. For example, Xerox is developing electronic paper: thin digital displays that respond to a stylus, like a pen on paper. Marks can be erased or saved digitally. Even with such technological advances, the increasing amounts of electronic data necessarily require more paper.

    “The information industry today is composed of a thin paper crust surrounding an electronic core,” Mr. Saffo wrote. The growing paper crust is most noticeable, but the hidden electronic core is far larger and growing more rapidly. The result is that we are becoming paperless, but we hardly notice at all. “That's one of the greatest ironies of the information age,” Saffo says. “It's just common sense that the more you talk to someone by phone or computer, it inevitably leads to a face-to-face meeting. The best thing for the aviation industry was the Internet.”

    Going to university is supposed to be a mind-broadening experience.

    That assumption is possibly made in contrast to training for work straight after school. But is it actually true? Jessika Golle of the University of Tubingen, Germany, thought she would try to find out.

    Her result, however, is not quite what might be expected. It shows that those who have been to university do indeed seem to leave with broader and more inquiring minds than those who have spent their immediate post-school years in vocational training for work. However, it is not the case that university broadens minds. Rather, work seems to narrow them.

    After studying the early career of 2095 German youngsters, Dr. Golle reached the conclusion.

    During the period under investigation, Germany had three tracks in its schools: a low one for pupils who would most probably leave school early and enter vocational training; a high one for those almost certain to enter university; and an intermediate one, from which there was a choice between the academic and vocational routes.

    The team used two standardized tests to assess their volunteers. One was of personality traits and the other of attitudes. They administered both tests twice once towards the end of each volunteer's time at school, and then again six years later.

    Of the original group, 382 were on the intermediate track, and it was on these that the researchers focused. Of them, 212 went to university and the remaining 170 chosen for vocational training and a job.

    When it came to the second round of tests, Dr Golle found that the personalities of those who had gone to university had not apparently changed. Those who had undergone vocational training and then got jobs were not that much changed in personality, either except in one crucial respect they had become more responsible.

    That sounds like a good thing, compared with the common public image of undergraduates as a bunch of pampered layabouts(娇生惯养的闲人). But changes in attitude the researchers recorded were more worrying. In the university group, again, none were detectable. But those who had chosen the vocational route showed marked drops in interest in tasks that are investigative and enterprising in nature.

    And that might restrict their choice of careers. Some investigative and enterprising jobs, such as scientific research, are, indeed off limits to the degreeless.

    But many, particularly in Germany, with its tradition of vocational training, are not. The researchers mention, for example, computer programmers, finance-sector workers and entrepreneurs as careers requiring these attributes.

    If Dr Golle is correct, and changes in attitude brought about by the very training Germany prides itself on are narrowing people's choices, that is indeed a matter of concern.
