Experts say children can begin learning a second language in preschool, and should begin before the age of ten to take advantage of young children’s natural ability to acquire language. This advantage is lost by the time most children encounter (遇到) a foreign language in the classroom, in middle school or high school.Dr. Noble Goss, an assistant professor of Spanish and German at Harding University in Arkansas, says, "As a father of bilingual (双语的) children (My wife is Mexican), I know that not only it is easy for children to learn one or more languages, but they have an amazing way of separating them out more successfully than you would think. "If a child hears two languages early, he accepts both equally. But if given a chance to speak both, can they be fluent in bothNot everyone agrees that early childhood is the only time to start a language, however. Reeves, the chairman and founder of the Center for Performance Assessment in Denver, Colorado, points to the Defense Language Institute’s success at training adult students to speak other language fluently."The frequently quoted argument that post-adolescence (青春期后) is too late to acquire foreign language skills is still a mystery," says Reeves.Still, if children are going to devote the six years or so of study it takes to master a second language, starting early just makes sense. Experts advise starting a foreign language early because（）.

MemoTo: Mr. Louis Johnson, PresidentFrom.. Margaret Ellis, Health ConsultantDate: December 1, 2010Subject. Improving Computer User’s ComfortEnclosed is the report, "Improving Computer User’s Comfort", which you asked me to prepare. The report summarizes current research on the effects of computers on health and recommends changes for our computer users.I interviewed over 60 employees of Far East Trade Development Company in the last six months and consulted with health experts in eye and wrist fatigue. I also reviewed all the current literature available for computer health hazards (危险).My recommendations are as follows.1. Anti-radiation (防辐身) screens should be available for computer monitors.2. Devices to support the wrist of the computer user should be used to help maintain proper wrist position during computer use and possibly reduce the risk of wrist illnesses.3. Employees need adjustable chairs which can give their backs a stronger support.For the technical possibility of designing the anti-radiation screens, you may consult Mr. Joseph Miller, and for the specific application of wrist-support devices, you may consult Mr. Benjamin Stone, Technical Department. If you have any other questions or would like to discuss my recommendations, please let me know.MemoTo: Mr Louis Johnson, PresidentFrom..

In relation to management attitude to absenteeism the study at the Prince William Hospital found similar results to the two 1989 studies.
Demands for stronger protection for wildlife in Britain sometimes hide the fact that similar needs are felt in the rest of Europe.Studies by the Council of Europe, of which 21 countries are members, have shown that 45 percent of rep-tile (爬行动物) species and 24 percent of butterflies are in danger of dying out.European concern for wildlife was outlined by Dr. Peter Baum, an expert in the Environment and Nature Resources Division of the Council, when he spoke at a conference arranged by the administrators (管理人员) of a British national park. The park is one of the few areas in Europe to hold the Council’s diploma for nature reserves of the highest quality, and Dr. Baum had come to present it to the park once again. He was afraid the public opinion was turning against national parks, and that those set up in the 1960s and 1970s could not be set up today. But Dr. Baum clearly remained a stronger supporter of the view that natural environments needed to be allowed to survive in peace in their own right.No area could be expected to survive both as a true nature reserve and as a tourist attraction, he went on. The short-sighted view that reserves had to serve immediate human demands for outdoor recreation (消遣) should be replaced by fui1 acceptance of their importance as places to preserve nature for the future.Dr. Baum went on. "We could manage without most industrial products, but we could not manage without nature. However, our natural environment areas, which are the original parts of our countryside, have become mere islands in a spoiled and highly polluted land. \ Dr. Baum came to visit one particular British national park mainly because（）
