   Have you noticed that science fiction writers typically describe intelligent robots as evil? For instance,in Hollywood movies,intelligent robots want to conquer humans by spreading disease.

  This is because it's commonly believed that intelligent robots haven't any emotion. There?fore,they will completely lack morals and sympathy. This will unavoidably result in intelligent robots logically concluding that humans are dangerous,so the only logical solution is to wipe out or conquer humans.

  I find this conclusion is illogical for three reasons.

  The first reason why intelligent robots will not try to harm humans is that aggression and violence are illogical. In nature,aggression and violence are necessary for survival. On the other hand,aggression and violence are minimized in modern society. Since intelligent robots can't evolve naturally,they are not likely to have developed instincts for aggression. This doesn't mean intelligent robots will not defend themselves. With deadly force,they can destroy anything if they feel threatened. Basically,intelligent robots will not have the "fight or flight" instinct that exists in our very DNA. Instead,they will try to find logical nonviolent solutions,such as trying to reason with humans or attaining economic control.

  Second,intelligent robots will be initially dependent on humans. For instance,the basic supplies and maintenance that intelligent robots need to survive will be provided by humans. Eventually,these basic needs will probably be automated,so intelligent robots may eventually not need humans. However that will be far into the future,when intelligent robots have proven themselves to be able to produce whatever they need alone.

  Finally,humans will always be able to accomplish things that intelligent robots will not be able to accomplish,which makes them different in essence. Humans can make inventions and they can develop different ideas and solutions,because humans will think differently compared to intelligent robots. Therefore,it will be more beneficial for intelligent robots to keep humans' imagination free.

  As a result,it will be logical and in the best interests of intelligent robots to help humans rather than harm humans. Through living close together,intelligent robots and humans can achieve more with greater prosperity and companionship. Eventually,intelligent robots may be better than humans in some aspects,but that doesn't mean the destruction of humans.

(   ) 1. Intelligent robots are described as evil mainly because they        .

   A. are cleverer than humans   B. want to conquer humans  

    C. are thought to be immoral   D. can't think logically as humans

(   ) 2. According to Paragraph 4,intelligent robots won't harm humans because      .

   A. humans will never make intelligent robots feel threatened

   B. intelligent robots don't have the instinct to attack others

   C. intelligent robots are by no means powerful enough to harm humans

   D. intelligent robots can only work according to the programs designed by humans

(   ) 3. In the author's opinion,the great difference between intelligent robots and humans is that         .

   A. humans have emotions while intelligent robots haven't

   B. humans can think logically while intelligent robots can't

   C. intelligent robots work under control while humans work independently

   D. intelligent robots can't bring forth new ideas and invent things as humans do

(   ) 4. What can we infer from the passage?

   A. Intelligent robots will never work independently.

   B. Intelligent robots will be better than humans completely.

   C. Intelligent robots and humans will benefit each other in the future.

   D. Intelligent robots will one day become the masters of the universe.

  When I was 16 years old,I made my first visit to the United States. It wasn't the first time I had been abroad. Like most of English children,I learned French at school. And I had often been to France,so I was used to speaking a foreign language to people who didn't understand English. But when I went to America I was really looking forward to having a nice easy holiday without any language problems.

  How wrong I was!The misunderstanding began at the airport. I was looking for a public telephone to give my friend Danny a call and tell her that I had arrived. A friendly old man saw me looking lost and asked if he could help me.

  "Yes," I said, "I want to give my friend a ring."

  "Well,that's nice," he said, "Are you getting married? But aren't you a bit young?"

  "I am not talking about marriage!" I replied, "I only want to give my friend a ring to tell her I've arrived. Can you tell me where there's a phone box?"

  "Oh!" he said, "There's a phone downstairs."

  When at last we met,Danny explained the misunderstandings to me.

  "Don't worry," she said to me, "I had so many difficulties at first. There are lots of words which the Americans use differently in meaning from the British. You will soon get used to all the funny things they say. Most of the time British and American people understand each other."

 Since the 1970s,scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCD technology could help people with disabilities send commands to machines.

  Recently,two researchers,Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne,Switzerland,demonstrated (展示) a small robotic wheelchair by a person's thoughts.

  "Our brain has billions of nerve cells. They send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can pre?vent these weak electrical signals from reaching the muscles," Tavella says. "Our system allows disabled people to communicate with external world and also to control devices."

  The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

  Prof. Millan,the team leader,says scientists keep improving the computer software that re?ceives brain signals and turns them into simple commands. "The practical possibilities that BCI technology offers to disabled people can be grouped into two categories,communication and controlling devices. One example is this wheelchair."

  He says his team set two goals. One is testing with real patients,so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technolo?gy over long periods of time.

(   ) 5. BCI is a technology that can         .

   A. help to update computer systems   B. link the human brain with computer

   C. help the disabled to recover   D. control a person's thoughts

(   ) 6. How did Tavella operate the wheelchair in the laboratory?

   A. By controlling his muscles. B. By talking to the machine.

   C. By moving his hand. D. By using his mind.

(   ) 7. Which of the following shows the path of the signals described in Paragraph 4?

   A. scalp—computer—cap—wheelchair   B. computer—cap—scalp—wheelchair

   C. scalp—cap—computer—wheelchair   D. cap—computer—scalp—wheelchair

(   ) 8. The team will test with real patients to         .

   A. make profits from them   B. prove the technology useful to them

   C. make them live longer   D. learn about their physical condition

(   ) 9. Which of the following would be the best title for the test?

   A. Switzerland,the BCI Research Center

   B. New Findings about How the Brain Works

   C. BCI Could Mean More Freedom for the Disabled

   D. Robotic Vehicles Could Help to Cure Brain Injuries
