3、 metallic device having the same general shape as a human being, performing humanlike functions, and responding to your questions in a monotone voice accentuated by high-pitched tones and beeps? This is the way many of us imagine a robot, but in the real world, a robot is not humanoid at all. Instea

4、d a robot often is a voiceless, box-shaped machine that efficiently carries out repetitive or dangerous functionsusually performed by humans. Today s robot is more than an automatic machine that performsone task again and again. A modern robot is programmed with varying degrees of artificial intelli

5、gence that is, a robot contains a computer program that tells it how to perform tasks associated with human intelligence, such as reasoning, drawing conclusions, and learning from past experience.A robot does not possess a human shape for the simple reason that a two-legged robot has great difficult

6、y remaining balanced. A robot does, however, move from place to place on wheels and axles that roll and rotate. A robot even has limbs that swivel and move in combination with joints and motors. To find its way in its surroundings1, a robot utilizes various built-in sensors. Antennae attached to the

7、資料僅供參考robot s base detect anything they bump into. If the robot starts to teeter as it moves on an incline, a gyroscope or a pendulum inside it senses the vertical differential. To determine its distance from an object and how quickly it will reach the object ，the robot bounces beams of laser light

8、and ultrasonic sound waves off obstructions in its path2. These and other sensors constantly feed information to the computer, which then analyzes the information and corrects or adjusts the robot s actions. As science and technology advance, the robot too will progress in its functions and use of a

9、rtificial-intelligence programs.當(dāng)你想到機器人的時候， 你腦海中浮現(xiàn)的是不是一個有著大致人類輪廓的、 能夠發(fā)揮像人類一樣的功能，而且能用夾著高音的單調(diào)音調(diào)回答你的問題的有光澤的金屬裝置？很多人想象中的機器人都是這個樣子的，可是，在現(xiàn)實世界中，機器人和人類長得一點都不像。 與之相反，機器人一般是一個不會說話的盒子狀機器， 能夠代替人類高效率地完成一些重復(fù)性的或者危險的工作?，F(xiàn)在的機器人不但僅是一臺能夠重復(fù)同一任務(wù)的自動工具， 而是具有不同程度的人工智能， 也就是說，機器人內(nèi)置了一個計算機程序， 能夠指資料僅供參考導(dǎo)機器人完成與人類智能有關(guān)的任務(wù)，比如推理、得出結(jié)論

10、，以及從過去的經(jīng)驗中學(xué)習(xí)。機器人不具備人形的原因是， 如果機器人有兩條腿的話，保持平衡會很困難。 機器人的移動主要依靠輪軸結(jié)構(gòu)旋轉(zhuǎn)來實現(xiàn)。 有的機器人甚至還能夠經(jīng)過接合點和發(fā)動機旋轉(zhuǎn)和移動的臂。機器人依靠多種內(nèi)置的感覺器來幫助尋找路徑。連接在機器人底部的天線能夠探測到機器人撞到的任何物體。在斜坡上移動的時候， 如果機器人開始搖晃， 機器人內(nèi)部的陀螺儀和鐘擺儀就會探測到水平方向的變化。機器人探測自己與其它物體的距離以及到達(dá)該物體的時間的方法是發(fā)射激光束和超聲波，經(jīng)過反射的信號來判斷這些信息。這些探測器不斷地向計算機提供信息，計算機將這些信息進行分析， 從而糾正或調(diào)整機器人的進一步動作。隨著科技的

11、進步， 機器人也會在功能和人工智能程序等方面上取得發(fā)展。When Our Eyes Serve Our StomachOur senses aren t just delivering汪 strict view of what s going on in the world; they affected by what s going on in our heads. A new study finds that hungry people see food-related r資料僅供參考words more clearly than people who ve justeaten.Psych

12、ologists have known for decades thatwhat s going on,inside our head affects oursenses. For example, poorer children think coinsare larger than they are, and hungry peoplethink pictures of food are brighter. Remi Radelof University of Nice Sophia-Antipolis，F(xiàn)rance，wanted to investigate how this happen

13、s. Does ithappen right away as the brain receives signalsfrom the eyes or a little later as the brainhigh-level thinking processes get involved.Radel recruited 42 students with a normalbody mass index. On the day of his or her test,each student was told to arrive at the lab atnoon after three or fou

14、r hours of not eating.Then they were told there was a delay. Somewere told to come back in 10 minutes; otherswere given an hour to get lunch first. So half thestudents were hungry when they did theexperiment and the other half had just eaten.For the experiment, the participant lookedat a computer screen. One by one, 80 wordsflashed on the screen for about l/300th of asecond each. They flashed at so small a siz
