   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.

  One day,my mother told me that Simon had blood cancer. Simon Sharp is my stepfather's nephew. Even though we aren't related by blood, Simonv is one of the most amazing people I have ever met and means more to me than any blood relative ever does. He likes riding his bike around Celebration, Florida. He also likes playing the piano. He is the kind of person that is impossible to forget once you meet him.

  My eyes shone with disbelief. "But he'll live,right?" I asked in a low voice. "There's no way to know for sure. He has a pretty rare case," my mom replied.

Simon seemed to get weaker and weaker. The doctors tried countless treatments,but each resulted in a worse reaction than the one before. Somehow,Simon went into remission. We were hopeful,knowing it might lead to a full recovery. The whole family was thrilled. Sadly,his health took a turn for the worse again a year later.

  It was around then that we received our "Simon Says..." T-shirts. On the front,in big blue letters,it read, "Simon Says.,." and when you turned it over it read, "Cancer is a detour,not a stop sign."That sentence showed me that no matter how hard the cancer fought against him,Simon and his loving family would do whatever it took to push fight through it. What im?pacted me even more was that it referred not only to Simon's battle,but also to the battles of all those who had a seemingly impossible challenge in their lifetime. Not too long after we got our shirts,Simon Sharp passed away when he was just fifteen years old.

  Simon touched countless people with his unique personality,kind soul,and extreme per?sistence even in his time of need. It was hard for everyone to overcome the sadness caused by the death of a family member,but we were able to. I think it's because we can wear our T?-shirts everywhere we go and proudly say, "Simon says..."

(   ) 5. Which of the following is true of Simon?

   A. He has a gift for music. B. He is an impressive boy.

   C. He once lived with the author. D. He is the author's distant cousin.

(   ) 6. What did Simon suggest by giving the T-shirts to his family?

   A. I love you all. B. Believe in me.

   C. I will never give up. D. Life is full of challenges.

(   ) 7. Who helped the author remove the sadness caused by Simon's death?

   A. Simon. B. The author himself.

   C. The author's mother. D. The author's stepfather.

(   ) 8. What would be the best title for the passage?

   A. Simon and I   B. Simon Says...

   C. Always Fight   D. Let Go of Sadness
