The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions. Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before. Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel. Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable. However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has produced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Industrialization is making natural resources become scarce. Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent. 可以自己删减 在提供一篇翻译的： 现代科技使生活更加便捷(Modern Technology Makes Life More Convenient) Modern technology makes life more convenient; tools are the milestores of the technology as well as human being’ s progress. Men used to cut trees with hand saw. But now, by using electronic saw they can cut down a tree in only a few minutes. Another example is more vivid: You have something urgent which has to be informed to your friend whose house is two hour’s ride away. You probably want to make a phone call. But no telephone is installed in your friend’ s home. What could you do? Nowadays, with modern technology advanting, using internet is popular with us. Some years ago, people had to get what they wanted through looking into a lot of information; at last people could become tired and spent too much time. Now, if you use Internet, all becomes a piece of cake. Only by clucking, you will gain what you expect. We all hope that modern technology will reach a higher level, because modern technology makes life more convenient indeed. [参考译文] 现代科技使生活更加便捷 现代科技使生活更加便捷；工具是科技进步和人类进步的里程碑.人类过去用手锯锯树,但是现在,用电锯可在几分钟内锯倒一棵树.另外一个例子更加生动形象：如果你有急事通知你的朋友,而他家距你家有2小时的路程,你可能想打个电话.但是你的朋友家又没安电话,你该怎么办?如今,随着现代科技的进步,使用网络已很流行.若干年前,人们不得不查找大量资料来搜集需要的信息,最后人累得疲惫不堪,还浪费了大量时间.现在,如果使用网络,一切就都是小菜一碟了.只要轻敲键盘,就会有求必应. 我们都期待着现代科技能达到一个更高的水平,因为现代科技确实使生活变得更便捷. 21st century is the century of technology. Nowadays, technology is everywhere around us. The development of technology has a significant affact toward the society. Several technologies that we usually use are the internet, computer, and cellphone. These new technologies make our life much easier and better. First, the development of computer changes our life. Decades ago, people needed to do lots of complex calculation on hand because they did not have computer, and more obvious, they did not have the software for calculation. As the result of that, people spent hours on the equations that a computer can solve in just a minute. Since the development of computer, people are able to use some kind of software to compute lots of complex functions and mathematical calculation. Computer becomes the most helpful equipment for the sciencists because they can use their time more efficiently. Also, internet is another useful tool for us today. The development of internet brings a great impact toward the society. Instead of going to library and fliping all the books to figure out some information, we can just simply use a mouse and click on the website to do research. The internet leads us to a place where we can find unlimited information and resources. It makes our life much easier and better. The last technology is cellphone. Nowadays, many people have a cellphone. But it just appears on the market for about 10 years. It is very convenience to the users because we can talk to anyone we want with a phone as small as a wallet. Also, we can communicate with others by making a phone call instead of sending letters. It is very fast and useful way to communicate. In conclusion, I believe the development of technology brings significant impact to our life. It is very helpful to us and I believe technology will keep improving in future. 高分范文 As is vividly depicted by the picture above, a traveler happily starts his journey by high-speed railway from Guangzhou to Wuhan. In the year of 2009, Wuhan-Guangzhou high-speed railway went into operation, reducing travelling time from 12 hours to 3 hours, bringing much convenience to the transportation between the two cities①. No wonder the caption in the picture says “with the Wu-Guang high-speed railway, cities far away is just like a place nearby”. Science and technology are the primary productive forces② and have been playing a key role in the national economy development. On the one hand, progress in science and technology has promoted economic and social progress greatly. Take the high-speed railway as an example. Firstly, the railway becomes a new engine③ of booming of regional economic. Secondly, the railway helps to attract a lot of tourists, so that tourism in these cities flourishes. Last but not the least, the load of the existing transportation network can be released to a great extent. On the other hand, with the development of science and technology, such as the operation of high-speed transportation, video phone, webcam meeting, the world has become smaller and smaller. It has long been a tradition for Chinese government to attach great importance to the advances④ in science and technology. Science and technology has successfully shaped an entirely new image of China on global stage via the two grand world events, 2008 Olympic Games and 2010 Shanghai World Expo. It is strongly advised that young people should devote themselves into the study of science and technology for “better city, better life”. 佳作妙译 如上图所示,一位旅客从广州踏上了去往武汉的高速铁路.2009年,武广高铁正式建成通车,将两地之间的行程从12小时缩短到3小时,极大地方便了两地的交通.难怪这幅漫画上写道“有了武广高铁,每个城市都在家门口”. 科技是第一生产力,在国民经济发展中扮演着重要角色.一方面,科技的进步促进了经济社会的快速进步.高速铁路就是鲜活的例子.首先这条铁路成为地区经济发展新的引擎.其次铁路吸引了大量游客,这些城市的旅游业随之繁荣起来.再次这条铁路很大程度上缓解了现有线路的运输压力.另一方面,随着科技的发展,高速铁路,视频电话,视频会议等应用会越来越多,世界将变得越来越小. 中国政府一直很重视科技的发展,通过2008北京奥运会和2010上海世博两件盛事,科技成功地重塑了中国在世界舞台上的国际形象.因此青少年要怀着“城市,让生活更美好”的信念,积极投身到对科技文化知识的学习上.

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 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 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.第二篇Not long ago, many people believed that babies only wanted food and to be kept warm and dry.

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 during 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 introduce 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. Gradually, 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!

Phonograph - History

The first great invention developed by Edison in Menlo Park was the tin foil phonograph. While working to improve the efficiency of a telegraph transmitter, he noted that the tape of the machine gave off a noise resembling spoken words when played at a high speed. This caused him to wonder if he could record a telephone message. He began experimenting with the diaphragm of a telephone receiver by attaching a needle to it. He reasoned that the needle could prick paper tape to record a message. His experiments led him to try a stylus on a tinfoil cylinder, which, to his great surprise, played back the short message he recorded, "Mary had a little lamb."

The word phonograph was the trade name for Edison's device, which played cylinders rather than discs. The machine had two needles: one for recording and one for playback. When you spoke into the mouthpiece, the sound vibrations of your voice would be indented onto the cylinder by the recording needle. This cylinder phonograph was the first machine that could record and reproduce sound created a sensation and brought Edison international fame.

Electricity and Lightbulb - History

Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. The idea of electric lighting was not new, and a number of people had worked on, and even developed forms of electric lighting. But up to that time, nothing had been developed that was remotely practical for home use. Edison's eventual achievement was inventing not just an incandescent electric light, but also an electric lighting system that contained all the elements necessary to make the incandescent light practical, safe, and economical. After one and a half years of work, success was achieved when an incandescent lamp with a filament of carbonized sewing thread burned for thirteen and a half hours.

There are a couple of other interesting things about the invention of the light bulb: While most of the attention was on the discovery of the right kind of filament that would work, Edison actually had to invent a total of seven system elements that were critical to the practical application of electric lights as an alternative to the gas lights that were prevalent in that day.

These were the development of:

 parallel circuit,

 durable light bulb,

 improved dynamo,

 underground conductor network,

 devices for maintaining constant voltage,

 fuses and insulating materials, and

 sockets with on-off switches.

Before Edison could make his millions, every one of these elements had to be invented and then, through careful trial and error, developed into practical, reproducible components. The first public demonstration of the Thomas Edison's incandescent lighting system was in December 1879, when the Menlo Park laboratory complex was electrically lighted. Edison spent the next several years creating the electric industry.

The modern electric utility industry began in the 1880s. It evolved from gas and electric carbon-arc commercial and street lighting systems. On September 4, 1882, the first commercial power station, located on Pearl Street in lower Manhattan, went into operation providing light and electricity power to customers in a one square mile area; the electric age had begun. Thomas Edison's Pearl Street electricity generating station introduced four key elements of a modern electric utility system. It featured reliable central generation, efficient distribution, a successful end use (in 1882, the light bulb), and a competitive price. A model of efficiency for its time, Pearl Street used one-third the fuel of its predecessors, burning about 10 pounds of coal per kilowatt hour, a "heat rate" equivalent of about 138,000 Btu per kilowatt hour. Initially the Pearl Street utility served 59 customers for about 24 cents per kilowatt hour. In the late 1880s, power demand for electric motors brought the industry from mainly nighttime lighting to 24-hour service and dramatically raised electricity demand for transportation and industry needs. By the end of the 1880s, small central stations dotted many . cities; each was limited to a few blocks area because of transmission inefficiencies of direct current (dc).

The success of his electric light brought Thomas Edison to new heights of fame and wealth, as electricity spread around the world. His various electric companies continued to grow until in 1889 they were brought together to form Edison General Electric. Despite the use of Edison in the company title however, he never controlled this company. The tremendous amount of capital needed to develop the incandescent lighting industry had necessitated the involvement of investment bankers such as . Morgan. When Edison General Electric merged with its leading competitor Thompson-Houston in 1892, Edison was dropped from the name, and the company became simply General Electric.
