Motorola Inc, the world"s second-largest mobile phone maker, will begin selling all of the technology needed to build a basic mobile phone to outside manufacturers, in a key change of strategy. The inventor of the cell phone, which has been troubled by missteps compounded by a recent industry slump in sales, is trying to become a neutral provider of mobile technology to rivals, with an eye toward fostering a much larger market than it could create itself. The Chicago area-based company, considered to have the widest range of technologies needed to build a phone, said it planned to make available chips, a design layout for the computer board, software, development tools and testing tools. Motorola has previously supplied mobile phone manufacturers with a couple of its chips, but this is the first time the company will offer its entire line of chips as well as a detailed blueprint. Mobile phones contain a variety of chips and components to control power, sound and amplification. Analysts said they liked the new strategy but were cautious about whether Motorola"s mobile phone competitors would want to buy the technology from a rival. The company, long known for its top-notch(等级) engineering culture, is hoping to profit from its mobile phone technology now that the basic technology to build a mobile phone has largely become a commodity. Motorola said it will begin offering the technology based on the next-generation GPRS (Global Packet Radio Service) standard because most mobile phone makers already have technology in place for current digital phones. GPRS offers faster access to data through "always on" network connections, and customers are charged only for the information they retrieve, rather than the length of download. Burgess said the new business will not conflict with Motorola"s own mobile phone business because the latter will remain competitive by offering advanced features and designs. Motorola"s phones have been criticized as being too complicated and expensive to manufacture, but Burgess said Motorola will simplify the technology in the phones by a third. In addition to basic technology, Burgess said, Motorola would also offer additional features such as Bluetooth, a technology that allows wireless communications at a short distance, and Global Positioning System, which tracks the user"s whereabouts, and MP3 audio capability.

China"s employment and re-employment situation remains tough with a surge this year in the number of graduates hitting the job market and in unemployment in general, a senior official said. The country"s registered average unemployment rate in urban areas reached 4 percent last year and is expected to go higher this year, Labour and Social Security Minister Zheng Silin told Xinhua yesterday. There are nearly 14 million laid-off workers in urban areas so far. And more than 10 million new graduates are predicted to enter the work force, Zheng said. To make things worse, the nation"s agricultural adjustment has forced more than 150 million rural workers to quit farming. Many of them will head to the cities to seek employment, posing uncertainties for the State, he said. Zheng, who was appointed as the minister during the first session of the 10th National People"s Congress in March, has urged his departments nationwide to do more to assist laid off workers to restart their lives.

Regular child care provided outside home or by someone other than the mother does not in itself undermine healthy emotional connections between mothers and their 15-month-old infants, according to a long-term national study. The finding holds even if care begins during the first 3 months after birth and runs for 30 hours or more per week. Among infants who receive unkind and unresponsive care from their mothers, however, the mother-child relationship may be damaged. "This research helps us put apart complexities regarding child care that have not previously been studied in detail," contends Jay Belsky, a psychologist. The investigation consists of 1,153 children and their families living in or near Boston. The youngsters, no more than 1 month old when they entered the study in 1991, will be tracked until the age of 7. Experimenters administered questionnaires to mothers in their homes and videotaped baby caretakers interacting with the kids at ages 1, 6, and 15 months. Independent observers rated the quality of each child care efforts and noted infant nervousness. Unlike most previous studies, this one allows researchers to observe each caretaker"s personality at child nursing, and kids" emotional reaction by the equipment.

Promptness is important in American business, academic, and social settings. The importance of punctuality is taught to young children in school. Tardy slips and the use of bells signal to the child that punctuality and time itself are to be respected. People who keep appointments are considered dependable. If people are late to job interviews, appointments, or classes, they are often viewed as unreliable and irresponsible. In the business world, "time is money" and companies may fine their executives for tardiness to business meetings. Of course it is not always possible to be punctual. Social and business etiquette also provides rules for late arrivals. Calling on the telephone if one is going to be more than a few minutes late for scheduled appointments is considered polite and is often expected. Keeping a date of a friend waiting beyond ten to twenty minutes is considered rode. On the other hand, arriving thirty minutes late to some parties is acceptable.

Jessica Bucknam shouts "tiao!" (tee-ow) and her fourth-grade students jump. "Dun!" (doo-wen) she commands, and they crouch(蹲). They giggle(吃吃地笑) as the commands keep coming in Mandarin Chinese. Half of the 340 students at the K-5 school are enrolled in the program. They can continue studying Chinese in middle and high schools. The goal: to speak like natives. About 24 000 American students are currently learning Chinese. Most are in high schools. But the number of younger students is growing in response to China"s emergence as a global superpower. "China has become a strong partner of the United States", says Mary Patterson, Woodstock"s principal. "Children who learn Chinese at a young age will have more opportunities for jobs in the future". Isabel Weiss, 9, isn"t thinking about the future. She thinks learning Chinese is fun. "when you hear people speaking in Chinese, you know what they"re saying", she says. "And they don"t know that you know".

The development of rapid transit rail lines in cities should parallel local economic development and blind construction of such lines should be avoided, a State Council conference said yesterday. The meeting, chaired by Premier Wen Jiabao, said the building of rapid-transit rail lines in cities should be carried out according to strict guidelines and management systems of such lines should be improved. It stressed that the amount of domestically made equipment used in such infrastructure projects needs to be increased. The meeting also deliberated on the draft amendments for laws governing the People"s Bank of China and commercial banks. Also discussed were the draft law on the supervision and management of banking sector and draft regulations on the management of central food reserves. It was agreed at the meeting that the laws governing the People"s Bank of China and commercial banks need to be amended so that the roles and responsibilities of the two are made clear.

Then, his staff captured a black baby bear for the President to shoot, but he could not. The thought of shooting a bear that was tied to a tree did not seem sporting, so he【B3】the life of the baby bear and set it free.

Happy hours are not necessarily happy, nor do they last for an hour, but they have become a part of the ritual of the office worker and businessman. On weekdays in pubs and bars throughout America, there is the late afternoon happy hour. The time may vary from place to place, but usually it is held from four to seven. After the workday is finished, office workers in large cities and small towns take a relaxing pause and do not go directly home. They head off instead for the nearest bar or pub to be with friends, coworkers and colleagues. Within minutes the pub is filled to capacity with businessmen and secretaries, office clerks and stock executives. They gather around the bar like birds around a fountain or forest animals around a watering hole and chat about the trifles of office life or matters more personal. This is their desert garden, the place to relieve the day"s stress at the office. At these happy hours, social binding occurs between people who share the same workplace or similar professions. They may chat about each other or talk about a planned project that has yet to meet a deadline. In this sense, these places become extensions of the workplace and constitute a good portion of one"s social life.

At the end of the U.S. Civil War, about four million slaves were freed. Now, people around the world can hear some of the former slaves" stories for the first time ever, as told in their own voices. "That was in slavery time", says Charlie Smith in one interview. "They sold the colored people. And they were bringing them from Africa. They brought me from Africa. I was a child". The Library of Congress released the collection of recordings, Voices from the Days of Slavery, in January. The recordings were made between 1932 and 1975. Speaking at least 60 years after their emancipation(解放), the storytellers discuss their experiences as slaves. They also tell about their lives as free men and women. Isom Moseley was just a boy at the time of emancipation, but he recalls that things were slow to change. "It was a year before the folks knew they were free", he says. Michael Taft, the head of the library"s archive of folk culture, says the recordings reveal something that written stories cannot. "The power of hearing someone speak is so much greater than reading something from the page", Taft says. "It"s how something is said—the dialect, the low pitches, the pauses—that helps tell the story".
