第一篇Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old.Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to identify which experiences can influence healthy development in human beings.Research scientists at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other human beings.

第三篇The authors develop and test a multiclassifier-based near-real-time face detection system based on the premise that a three-part strategy is necessary for designing real-time face detection systems that provide high detection rates. The critical factors for real-time face detection are based on a framework of multiple classification functions: (1) a skin classification function is used as the preliminary stage in order to prune the search, localize the computation, and therefore improve performance time; (2) subsequently, three coarse-to-fine statistical model based classifiers are used to scan the windows and discard most non-face windows; and (3) finally, faces and non-faces are verified from images. The bagging ensemble algorithm (bootstrap aggregating) is also applied to improve the performance of detection rates.
第四篇Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient —no matter where he or she may be.
Online doctors offering advice based on normal symptoms(症状) are the most obvious example. Increasingly, however, remote diagnosis(远程诊断) will be based on real physiological data(生理数据) from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural(countryside) care. And at least one team wants to use telemedicine as a tool for disaster need—especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex(复杂的) medical pictures around the world — CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs ring disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’ opinions and diagnosis are common.（这片有点长）
第五篇High-Tech Expo will be quietly into the footsteps of our campus, the annual "scientific and technological Month" activities started!

⑻ 关于科技的英语小短文
基因改造食物安全吗？
- 鼓吹基因改造作物的人说，这类作物不像传统作物，需要的有毒农药较少，对环境有利。但令批评者担忧的是潜在的风险，他们想知道所谓的利益究竟有多少。到底基因改造作物是环保美梦的实现，还是一场正在形成中的灾难？科学家正积极寻找答案。
人们对基因改造食物的态度，似乎愈来愈壁垒分明，一边的人支持，另一边的人则是畏惧。支持者宣称，种植基因改造作物对环境伤害较小，而食用这种农作物制成的食品也完全无害。它们还说，基因工程让农作物在贫瘠的土地上也能生长，或可培育出更营养的食物。在不久的未来，全球人口快速膨胀，还得靠这方法解决粮食问题。持怀疑态度者则反驳，基因改造作物对生态环境或人体健康都有极大的风险，令人忧心，不该贸然接受。许多欧洲国家抱持这种态度，因而限制基因改造作物的种植与输入。主要的争议，集中在基因改造食物的安全性。然而，最近的科学研究又是如何看待基因改造食物的危险呢？答案，往往迷失在各种报导的争议中；但是在接下来的篇幅里，它们将呈现在你的眼前。
GENETICALLY MODIFIED FOODS: Are They Safe?
- Are genetically modified crops an environmental dream come true or a disaster in the making? Scientists are looking for answers
The world seems increasingly divided into those who favor genetically modified (GM) foods and those who fear them. Advocates assert that growing genetically altered crops can be kinder to the environment and that eating foods from those plants is perfectly safe. And, they say, genetic engineering－which can ince plants to grow in poor soils or to proce more nutritious foods－will soon become an essential tool for helping to feed the world's burgeoning population. Skeptics contend that GM crops could pose unique risks to the environment and to health－risks too troubling to accept placidly. Taking that view, many European countries are restricting the planting and importation of GM agricultural procts. Much of the debate hinges on perceptions of safety. But what exactly does recent scientific research say about the hazards? The answers, too often lost in reports on the controversy, are served up in the pages that follow.
