Biorobotics is a field within robotic science that is based on the movements of living things.The most famous biorobots look and move a lot like humans.However,there are several robots that have been made to mimic (模仿) animals.While many companies develop such robots as toys,some are used for practical purposes.

One example of a biorobot is a flying robot that is based on the movements of bees.The robot,named “Carlton”,was developed by the German Research Center for Artificial Intelligence.Built to be both light and powerful,it can hover like a bee in tight spaces and also change direction without losing speed.This robot’s abilities make it very useful for military and police search and rescue missions.For

example,Carlton can hide behind a tall wall,rise up to quickly look at what is on the other side,and then hide again.It can also send video images of what it sees to soldiers in a safe location far away.

“Modsnake” is a robot that was modeled on snakes.This robot was developed by the Carnegie Mellon University Biorobotics Lab.It is made to move like a snake,so it can pass through narrow spaces,move over all sorts of obstacles,climb poles,and even swim.The way Modsnake moves makes it useful for a variety of tasks such as checking for survivors in fallen buildings,finding damaged areas inside of pipes and cleaning up oil spills in lakes and rivers.

A third robot,based on cockroaches,also has several uses.“Sprawl” was designed by a research team at Stanford University to take videos and recover small objects.Like many six-legged robots,Sprawl was made to move like an insect.However,Sprawl is uncommonly fast and strong for its size,just like a real cockroach.These characteristics make it particularly useful for military situations in which an enemy might try to disable it.It is very difficult to shoot because it moves quickly and is relatively small.Even if an enemy shoots Sprawl,it can usually keep functioning.

The American writer J.D.Salinger is known for his reclusive (隐居的) nature.He has not given an interview since 1974,or published any new work since 1965.Salinger’s entire published works consist of one novel and 13 short stories,all written in the period 1948-1959.In 1997,a rumour started that Salinger was going to bring out the first book version of his last published story.Fans became very

excited.However,because of the publicity,Salinger quickly receded from the arrangement.

Ironically (讽刺地) for a future writer,when he was at college one of his professors insisted he was the worst English student in the history of the college.Before writing his famous book,he had only published a few short stories in magazines.

Salinger established his reputation with a single novel,The Catcher in the Rye (1951),an immediate bestseller which still sells 250,000 copies per year.The main character,Holden Caulfield,is a

sensitive,rebellious (叛逆的) teenager experiencing the growing pains of high school.

Salinger did not do much to help publicise his masterpiece and asked that his photograph should not be used in connection with it.The public attention which followed the success of the book led him to move from New York to the faraway hills of Cornish,New Hampshire.Since the late 1960s he has tried to escape publicity.In 1974 he told a reporter that he liked to write but that he wrote for himself and his own pleasure.

Later,he tried to stop the publication of a biography which included letters he had written to other authors and friends.In 2000 his daughter published a biography.In it she stated her father was not a recluse.She said he travelled often and had friends all over the world.She added that he enjoyed being with people and was friendly except where publicity and celebrity are concerned.

Salinger refused to sell the movie rights to any of his stories to Hollywood and would not allow any

of his works to be involved with film.
