Real World Robots
When you think of a robot,do you envision a shiny,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.Instead a robot often is a voiceless,box-shaped machine that efficiently carries out repetitive or dangerous functions usually performed by humans.Today‘s robot is more than an automatic machine that performs one task again and again.A modern robot is programmed with varying degrees of artificial intelligence—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 difficulty 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 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 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 artificial-intelligence programs.

練習(xí)：
1.Another good title for this passage would be
A Robots： Taking the Place of Humans.
B Artificial Intelligence Programs.
C Today‘s Robots and How They Function.
D Modern-Day Sensors.
2.Artificial intelligence is
A the unnatural way in which robots move.
B a voiceless,box-shaped machine that performs repetitive tasks.
C sensors such as antennae and a gyroscope.
D a computer program that imitates human intellectual processes.
3.The last paragraph suggests that future robots will be
A more humanlike in behavior and actions.
B more like automatic machines.
C better able to move on inclines.
D better equipped with laser light sensors.
4.The writer begins the passage by comparing
A the shape of a human being with a box.
B a modem robot with a fictional robot.
C an imaginary machine with a human.
D a computer program with artificial intelligence.
5.The word humanoid means
A lacking human characteristics.

答案與題解：
1.C 從文中得知，文章主要介紹了機(jī)器人和它們的運(yùn)行方式，因此選擇C選項(xiàng)。
2.D Artificial是“人工”的意思，intelligence是“智能”的意思。另外從文中得知，機(jī)器人使用artificial intelligence能夠進(jìn)行與人類類似的推理分析等活動(dòng)，因此可知它是一種類似人類智能的計(jì)算機(jī)程序。
3.A 最后一段講機(jī)器人的'發(fā)展方向是更加智能，能夠自己判斷并修正行為，而不僅僅是完成重復(fù)性的工作。
4.B 文章開(kāi)頭的時(shí)候作者讓讀者描述他們腦海中的機(jī)器人概念，并隨后介紹了實(shí)際的機(jī)器人是怎樣的，因此選擇B選項(xiàng)。
5.D 從humanoid的詞根human可看出這個(gè)詞是形容與人類有關(guān)的特征。另外根據(jù)文章對(duì)這個(gè)詞的描述可以得出這個(gè)詞是表示和人類類似的特征，不管是外形上，還是行為方式上。
