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.
不久之前,许多人认为婴儿的基本需求是食物和保持温暖干燥.人们以为婴儿只有到了五六个月大的时候才会开始学东西.
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.
然而,美国的医生声称婴儿在他们出生的头几天便开始学习.肯尼迪施莱佛国立儿童健康和人类发展机构是联邦政府代理机构,他的目标是鉴别那些能影响人类健康发展的经验.

3. 急求！英语短文 What does new technology bring us（新科技带给我们什么）
we adopt a new teaching method this term, the autonomous learning, as we call it. the school sets aside about 3 million Yuan to set up an autonomous learning center with 270 computers and a study network. before it was ready for lessons, all of us had pictured the wonderful and promising future in English teaching and the efficiency of the teaching. however, e to some technical defects and power failure, i have some very depressive mornings having my english lessons there.
one question lingers in my mind now:"what does modern technology bring us?"
Time-saving or Time-wasting? A convenience or An inconvenience?
with the development of modern technology, more and more inventions appear. what's more, the inventions is upgraded so fast that you often find that the "high-tech gadget" you bought last year almost turned into a stack of rubbish compared to its pioneer proct this year. then we buy a new one, we lag behind others, and we buy the latest one... everytime we buy a new thing, we spend a lot of time to learn the instructions. and i find that the electronic procts nowadys break down so easily. i bought a new MP3 to my father last year, and it broke down twice by far. everytime it broke down, we had to wait 15 days for the repairment, thus causing much inconviniece to us, because we are so used to the life with it, we can't live without it now.
take the invention of cars for another example. its invention is supposed to enable us to travel faster and more conviniently. however, what happens now? the traffic jams for hours! pollution apart, the car slows us down instead of speeding us up. everytime i see the traffic jams in our city ring the rush hour, i feel i am lucky that i don't have a car myself. if i had a car, i should spend time to learn driving, memorize the traffic rule, drive my cars for car maintenance, have it fixed when it breaks down...how much time would i waste on a car, i wondered.
and let's go back to my classroom. when i began my teaching in the year 2000, my students and i had a not-bad time, learning english and playing interesting games together. there weren't enough english language labs for listening course, so the teachers carried a radio cassette recorder to the classroom and played the tapes. Thanks to the high-tech, the new language labs were built up. we felt very happy and moved our listening lessons into the labs. we were happy for only one or two years. as time went by, the language labs soon wore out. the computer broke down easily e to the virus and the earphones refuse to work because of the poor quality and improper uses by the students. precious time is wasted when the teacher arrives at the classroom one morning and suddenly finds the computer doesn't work. can we use the radio cassette recorder? NO! all the listening materials are stored in the U-disk and brought to the classroom! we have no choice but to wait for the technician, who can always be rather busy or lazy.
what does modern technology really bring to us? now i am also thinking about another quesiton:" if my computer breaks down right now and this article suddenly disappear, how will i feel and what should i do?"

As children, both Franklin and Edison had limited schooling.Both inventors are said to have self-taught themselves mostly through their love of reading.Franklin and Edison were both interested in electricity, and I think they would have had a lot to talk about if they had ever met face-to-face.They were different too though. They lived in very different times. While Benjamin Franklin discovered electricity. Edison's inventions and discoveries all required electrical currents: light bulbs, microphones, phonographs, fluoroscopes, etc.我好想成为科学家，因为如果我是一名科学家，我就可以创造出许多有用的东西，科学家的英语作文。

如果长大了我当上科学家，我就会发明或发现很多东西来提高我们国家高科技水平，为我们的学习、工作、生活带来许多方便，所以我现在要好好学习，积累生活和社会知识，争取长大以后当上伟大的科学家，做一个有益于社会和人民的人。
科学家是怎样炼成的？当然不是凭空出现的，他们的出现必然是有一个或多个因素导致的。
首先，要是一个很爱动脑，并且对科学极其热爱的人，这是一切因素的承载者，是为基础，是成为一个科学家的前提。
其次，要有一定的资金。
资金——作为科学研究的物质保证，起着不可替代的作用，它也决定着一个科不家能否完成他自己的实验，能否成为一个有名的科学家。
第三，也是最重要的，这个人要有坚定不移的意念，为科学研究献身的意念，还要有耐心，因为进行科学研究的过程必定是枯燥的，只有耐得住寂寞的人才能完整，完美地完成研究。
然后，就是作为一位科学家，一定要有在一定要有丰富的想象力，只有有了想象力，才能够想象到以前从未出现过的东西，然后进行研究，最终完成发明。
试想，如果爱迪生没有在大脑中完成为电灯的设想，那么，又从何而来的那一千零一次的努力，从何而来我们现在的灯火通明。
所以想象力也是十分重要的。
可见，一个人之所以能够成为发明家，不是只要勤奋这一项就足够的，而是多种因素集中在一个人的身上而炼就的。

科学实验为题的英语作文80字
In ancient times, many people believed the earth was a flat disc. Well over 2,000 years ago; the ancient Greek philosophers were able to put forward o good arguments proving that it was not. Direct observations of heavenly bodies were the basis of both these arguments. First, the Greeks knew that ring eclipses of the moon the earth was beeen the sun and the moon, and they saw that ring these eclipses, the earth's shadow on the moon was always round, they realized that this could be true only if the earth was spherical, If the earth was a flat disc, then its shadow ring eclipses would not be a perfect circle; it would be stretched out into a long ellipse. The second argument was based on what the Greeks saw ring their travels. They noticed that the North Star, or Polaris, appeared lower in the sky when they traveled south, in the more northerly regions, the North Star appeared to them to be much higher in the sky. By the way, it was also from this difference in the apparent position of the North Star that the Greeks first calculated the approximate distance around the circumference of the earth, a figure recorded in ancient documents says 400.000 stadium, that's the plural of the world stadium. Today, it's not known exactly what length one stadium represents, but let's say it was about 200 meters, the length of many athletic stadiums. This would make the Greeks estimate about ice the figure accepted today, a very good estimate for those writing so long before even the first telescope was invented.

My grandmother became a widow in 1970. Shortly after that, we went to the animal shelter to pick out a puppy to keep her pany. Grandma decided on a little terrier that had a reddish-brown spot above each eye. Because of these spots, the dog was promptly named Penny.Grandma and Penny quickly became very attached to each other, but that attachment grew much stronger about three years later when Grandma had a stroke. Grandma could no longer work, so when she came home from the hospital, she and Penny were constant panions.After her stroke, it became a real problem for Grandma to let Penny in and out because the door was at the bottom of a flight of stairs. So a mechani *** using a rope and pulley was installed from the back door to a handle at the top of the stairs. Grandma just had to pull the handle to open and close the door. If the store was out of Penny's favorite dog food, Grandma would make one of us cook Penny browned beef with diced potatoes in it. I can remember teasing my grandmother that she loved that dog better than she loved her family.As the years passed, Grandma and Penny became inseparable. Grandma's old house could be filled to the brim with people, but if Grandma went to take her nap, Penny walked along beside her and stayed by her side until she awoke. As Penny aged, she could no longer jump up on the bed to lay next to Grandma, so she laid on the rug beside the bed. If Grandma went into the bathroom, Penny would hobble along beside her, wait outside the door and acpany her back to the bed or chair. Grandma never went anywhere without her faithful panion by her side.The time came when both my grandmother and Penny's health were failing fast. Penny couldn't get around very well, and Grandma had been hospitalized several times. My uncle and I lived with Grandma, so Penny was never left alone, even when Grandma was in the hospital. During these times, Penny sat at the window looking out for the car bringing Grandma home and would excitedly wait at the door when Grandma came through it. Each homeing was a grand reunion beeen the o.On Christmas Day in 1985, Grandma was again taken to the hospital. Penny, as usual, sat watching out the window for the car bringing Grandma home. Two mornings later when the dog woke up, she couldn't seem to work out the stiffness in her hips as she usually did. The same morning, she began having seizures. At age fifteen, we knew it was time. My mother and aunt took her to the veterinarian and stayed with her until the end.Now the big dilemma was whether to tell Grandma while she was still in the hospital or wait. The decision was made to tell her while she was in the hospital because when we pulled up at the house, the first thing Grandma would look for was her beloved Penny watching out the window and then happily greeting her at the door. Grandma shed some tears but said she knew that it had to be done so Penny wouldn't suffer.That night while still in the hospital, Grandma had a massive heart attack. The doctors frantically worked on her but could not revive her. After fifteen years of loving panionship, Grandma and Penny passed away within a few hours of each other. God had it all worked out – Penny was waiting at door when Grandma came Home. 我的祖母成了寡妇， 1970 .不久，我们去畜舍挑小狗陪她.奶奶决定对小猎犬了红褐色场以上，每眼.由于这些景点中，狗被及时命名为竹. 奶奶及竹很快成了非常重视对方，但扣押的增长十分强劲，约三年后，当外婆了，终年65岁.外婆不能再工作，所以当她回家，从医院，她和竹不断的同伴. 之后她中风，它成为一个真正的问题，奶奶让竹中出，因为大门在底层的楼梯.这样一个机制，用绳子和滑轮装置，从后门句柄在顶部的楼梯.奶奶刚拉把手打开和关闭车门.如果商店是出一分钱的狗喜爱的食物，奶奶将使我们其中库克竹馅料牛肉与洋葱，土豆而已.我记得取笑我姥姥说，她很喜欢狗比她爱她的家人. 随着岁月的推移，奶奶及竹成为密不可分的.奶奶的老房子可填至7.6人，但是如果奶奶去把她的行动，竹走过身旁待在她身旁，直到她醒来.至于竹岁，她再也无法跳起来于床上，以奠定未来阿妈，让她放在地毯旁边的床上.如果奶奶走进浴室，将竹蹒跚沿她旁边，等候在门外，并陪同她回到床上或椅子.奶奶没任何未经她的忠实伴侣的身旁. 时间来到时，无论是我的祖母和篙生均未能迅速.竹不能惟我独尊很好，奶奶曾多次住院.我叔叔和我住同奶奶，让竹从来孑然一身，连奶奶时，在医院昏迷了.在这些时候，竹坐在窗口看出去，为使汽车奶奶回家就会兴奋等候在门口时，奶奶进来.每颂是一个规模宏大的团聚两者之间. 圣诞节当日，在1985年，外婆又被送往医院.竹...

2 How to learn English wellLearning English just like learning any other language, is hard work so my first advice is to spend much time practicing using English every day. Besides, we should listen to the teacher and take notes carefully in class. Go over what is learnt regularly and finish doing our homework carefully. Listen to English radio programmes, read English stories and newspapers, watch English films and TV programmes ,keep a diary in English and attend English debbates and speech contests. If we make mistakes, correct them at once and try not to make the same mistakes. What's more, we should look up new words in the dictionary before class and prepare each lesson carefully before class. I believe if we work hard and have good ways of learning English, we will learn English well.学习英语就象学习其他语言一样是艰辛的。
因此我的第一个建议是每天花多点时间练习使用英语。
除此之外，我们应该上课认真听讲、记笔记。
定期复习所学内容，认真做作业。
听英语广播，读英语故事和报纸，看英语电影和电视节目，用英语写日记，参加英语讨论和演讲比赛。
如果我们犯错误，就要立刻改正，尽力下次不要犯同样的错误。
而且，我们在上课前要查字典，认真准备每节课。
我相信如果我们努力学习、有好的学习方法，我们会学好英语的。
希望对你有帮助，祝：学业有成，更上一层楼

人类大脑智力的决定因素
There are two factors which determine an indivial's intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an indivial will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the indivial— the sort of environment in which he is brought up. If an indivial is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.
The importance of environment in determining an indivial's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(抚养) homes. Peter was raised by parents of low intelligence in an isolated community with poor ecational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

我的朋友索菲亚布伦特
Sophy Brent came to visit me nearly every day. She made me feel uneasy most of the time. She smoked 11 and never used an ashtray. She followed me into the kitchen while I made tea or coffee or supper and 12 herself to the children's orange juice. She made a great hit with my two-year-old daughter Flora, who would 13 about her for hours and refer to her lovingly as "sofa", and she was always talking about my husband and asking me where he was.
I could not decide why she chose my 14 , although I realized that nobody else paid her very much attention. Her situation was very difficult in that she was 15 out of drama school and only nineteen, but being 16 to play a leading part in a company of fairly 17 and experienced actors. They would not have liked her much even if she had been good, and as, from all accounts, she was not good so they took every 18 to run her down. I think she thought that I was the only person around who was both unconnected with the theatre and tolerably 19 . To associate with me was not, at any rate, to step down the scale. And for my part, although I felt troubled by her I did not dislike her. There was something genuinely outstanding in her personality, and she had such physical 20 that with me she could get away with anything. She was nice to have around, like flowers or a bowl of fruit.

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! We look forward to the most interesting is the High-Tech Expo will be it! Day after day passed, and finally to Saturdays! It is with emotion sitting in their seats, Hao teacher "order", we will quickly pick up the experimental equipment in high spirits to start the experiment. "We have to do is this group of 'interesting siphon' welcome to visit!" I cried loudly, Sun Xuhui only curiosity left over, we looked suspicious, I did not miss a good opportunity for each, said: " , Take a look at our test! "You do not want to see the glass reversed, changing the water will be able to go to it? "I like the" bombard "like to introce a non-stop," Oh, look carefully! First of all, the pipe filled with water, followed after a glass of water, access to water 1 cup on the table, the empty 2 cup lightly boosting, and low point, "Bai Baishou I let Yan Kai-day 2 cups hold air at the same time Fanlianniejin the end of the tube, I gently hose and hold the other end, went on to say: "I have to do a good job of this process, and then look! Now, we were put on both ends of the glass are No. 1 and No. 2 empty cup, there have been wonderful scene, 1 cup of water flow on a 2 cup. Graally, you will find that 1 cup of the air, on the contrary, the 2 cups filled with 1 cup of water. You want to know why? "Sun Xuhui see Huale Yan, Siyousiwu nodded, as if a child's desire for knowledge, taking advantage of this time, I had to step up the" attack ":" The principle is to siphon hose in the liquid, and the two ends are Niejin So Guanzi have a negative pressure, and then put them into two cups, to promote access to the water hose, which is siphon! "I nod after presentation, Sun Xuhui nodded, satisfied to leave our team. High-Tech Expo will, "visit" the group more and more people, this could be really popular science projects ah! High-Tech Expo will be the end, I think wistfully: Qin minds, our life is full of interesting, original, primary and secondary school students which we can hold our own, "Cobo" Yes!
