機器人的發(fā)展

Robots， becoming increasingly prevalent in factories and industrial plants throughout the developed world， are programmed and engineered to perform industrial tasks without human intervention. Most of todays robots are employed in the automotive industry， where they are programmed to take over such jobs as welding and spray painting automobile and truck bodies.

機器人在所有發(fā)達國家的工廠日益普及，人們對它們進行編程和設(shè)計，使其在無人情況下執(zhí)行工業(yè)任務(wù)?，F(xiàn)今，大多數(shù)機器人用于汽車工業(yè)，人們對其編程，從事如汽車和卡車車身焊接、噴漆之類的工作。

What makes a robot a robot and not just another kind of automatic machine？ Robots differ from automatic machines in that after completion of one specific task， they can be reprogrammed by a computer to do another one. As an example， a robot doing spot welding one month can be reprogrammed and switched to spray painting the next. Automatic machine， on the other hand， are not capable of many different uses; they are built to perform only one task.

是什么使機器人變成機器人而不是其他的自動化機器呢？機器人與自動化機器的區(qū)別在于：機器人完成一項特定工作后，它們可以被電腦重新編程去執(zhí)行另一項任務(wù)。比如，一個機器人做了一個月的點焊，可以被重新編程，并在下個月轉(zhuǎn)向噴漆。相反，自動化機器卻沒有許多不同的用途，它們只能執(zhí)行一項任務(wù)。

The next generation of robots will be able to see objects， will have a sense of touch， and will make critical decisions. Engineers skilled in microelectronics and computer technology are developing artificial vision for robots. With the ability to “see”， robots can identify and inspect one specific class of objects out of a stack of different kinds of materials. One robot vision system used electronic digital cameras containing many rows of light-sensitive materials. When light from an object such as a machine part strikes the camera， the sensitive materials measure the intensity of light and convert the light rays into a range of numbers. The numbers are part of a grayscale system in which brightness is measured in a range of values. One scale ranges from 0 to 15， and another from 0 to 255. The 0 is represented by black. The highest number is white. The numbers between are represented by different shades of gray. The computer then makes the calculations and converts the numbers into a picture that shows an image of the object in question.

下一代機器人將能看見物體，具有觸覺，能做出關(guān)鍵性的決定。精通微電子和電腦技術(shù)的工程師正在為機器人開發(fā)人造視力，有了“看”的能力，機器人就能從一堆不同的材料中鑒別檢查出具體的某一類物體。機器人視覺系統(tǒng)采用包含多行感光材料的電子數(shù)碼相機。當(dāng)一個物體上的光，如機器零件，照射到相機上時，敏感材料就可測量出光的強度，把光線轉(zhuǎn)換為一組數(shù)字。這些數(shù)字是灰度系統(tǒng)的一部分，其亮度由一系列數(shù)值測量。一個刻度范圍是0到15，另一個是0到255。0用黑色表示，最高值用白色，其間的數(shù)值用不同的灰色陰影來表示。然后計算機進行計算，并將數(shù)字轉(zhuǎn)換為表明該物體形象的圖像。

Engineers are designing and experimenting with new types of metal hands and fingers， giving robots a sense of touch. Some engineers are writing new programs allowing robots to make decisions such as whether to discard defective parts in finished products. To do this， the robot will also have to be capable of identifying those defective parts.

工程技術(shù)人員正在設(shè)計和試驗新型金屬手臂和手指，使機器人具有觸覺。一些工程人員正在編寫新的程序，使機器人能做出決定，諸如是否丟棄成品中有缺陷的零件。要做到這點，機器人還必須具有鑒別有缺陷零件的能力。

These future robots， assembled with a sense of touch and the ability to see and make decisions， will have plenty of work to do. They can be used to explore for minerals on the ocean floor or in deep areas of mines too dangerous for humans to enter. They will work as gas station attendants， firemen， housekeepers， and security personnel. Anyone wanting to understand the industry of the future will have to know about robotics.

集觸覺、視覺和做決定能力于一體的未來機器人將會做大量工作。它們可以用于探測海底的礦物，或者探測對人類來說太危險而不能進入的礦井深處。它們可以做加油站服務(wù)人員、消防人員、房屋管理員和安全人員的工作。任何想了解未來工業(yè)的人必須懂得機器人技術(shù)。

Dear Tom，

I am sorry to tell you that I cant keep my promise that I will pay a visit to Beijing with you next weekend. Im afraid we will have to make it another time， because I will be meeting my uncle at the airport next weekend. I havent seen him for almost ten years. He is on business from Australia， and will be here for only two days. It is a rare chance for our family to come together again.

If it is convenient for you， we can make it the weekend after next. Once again， I am sorry for any inconvenience caused.

Why dont you go and attend the lecture？ I know you have taken a special interest in traditional Chinese culture， so I think this is a good opportunity for you to develop your understanding of what it is like.

Im sure you will find the lecture worth listening to.

In order to encourage the students to take outdoor exercise， our school organized a mountain-climbing activity on April 10. At 8：00 am， we reached the foot of Daqing Mountain and set out for the top in high spirits. All the way we were talking， singing and laughing， enjoying the fresh air and the beautiful scenery. When some fell behind， others would come and offer help. About 2 hours later， we all reached the top.

There is no doubt that we had a good chance to get close to nature and relax from heavy school work. The activity also improved the friendship between us students. What a wonderful time！

Building a Good Relationship with Our Teachers

As a senior high student， I think it is necessary to build a good relationship with our teachers. We students can always get support and advice from them， from which we learn a lot and feel good about ourselves.

In my opinion， this relationship should be one filled with love， care， understanding and respect， so we can exchange ideas freely. To build a relationship of this kind， we students should trust teachers and express our feelings honestly so that they can become our friends. Only in this way can we enjoy a warm relationship between teachers and students and live a happy and healthy school life.

NOTICE

Dear friends，

Id like to offer some tips to those students who will go abroad so that you can avoid trouble and make your trip more pleasant.

First of all， you should carry your passports and some money and take good care of your passports and wallets， without which you could do nothing in a strange land. It is necessary to take some clothes and medicine in case the weather changes and you might fall ill. During your stay in Australia， you should never go out alone to avoid getting lost. In addition， you should mind your behavior wherever you go and whatever you do because you represent the Chinese people. You should behave properly and establish a good image.

If you follow my advice， I am sure you will enjoy your trip.
