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.

Researchers from the University of Haifa-Oranim have managed to make out the "self-irri-gating" mechanism (构造) of the desert rhubarb,which enables it to harvest 16 times the amount of water than otherwise expected for a plant in the Negev Desert. This is the first example of a selfirrigating plant worldwide.

The desert rhubarb grows in the mountains of Israel's Negev Desert,where the average rainfall is particularly low (75 mm per year) . Unlike most of the other desert plant species,which have small leaves so as to reduce water loss,this plant is unique in that its leaves are par?ticularly large.

Professor Simcha Lev-Yadun,Professor Gidi Ne'e man and Professor Gadi Katzir came across this unique plant while studying the field area,and noticed that its waxy leaves are unusually large. They observed a ridged (成脊状的) structure on each leaf.

The scientists explained that these deep and wide depressions (凹陷) in the leaves create a "channeling" mountainlike system by which the rain water is channeled toward the ground sur?rounding the plant's deep root. Other desert plants simply absorb the rain water that goes through the ground in its immediate surroundings.

The findings have shown that the natural selection process has resulted in the evolution of this plant's extremely large leaves,which improved its ability to survive in the arid climate of the desert. The results of experiments and analysis of the plant's growth―in an area with an average annual rainfall of 75 mm―showed that the desert rhubarb is able to harvest quantities of water that are 16 times the amount of water harvested by the smallleafed plants of the Negev Desert. When the research team watered the pJant artificially,they observed how the water flows along the course of the leaves' depressions to the ground surrounding the plant's single root and then goes through the ground to a depth of 10 cm or more. Under the experimental condi?tions,water goes through the ground only as deep as 1 cm. "We know of no other plant in the deserts of the world that functions in this manner," the researchers concluded.

After a boy had unwrapped his gifts on Christmas morning,his mother asked him which present he wanted to donate.

"None," the 5-year-old boy replied. His mother explained that sharing was part of the holiday spirit. She also explained that a poor child would be very happy to receive a gift. The boy eventually agreed to part with (舍弃) one of his gifts. He put his four gifts in front of him and tried to decide which one to part with. It was a difficult decision,but he chose to say goodbye to the flute (长笛) ."Where do we take it?" he asked his mother. His mother explained that there was a Salvation Army box two streets away and someone would give the gifts to children who needed them.

This parting with a gift became a yearly activity. When he was 8 years old,the boy treas?ured the gifts he had received so much that his decision needed to be made using a special method,which led him to part with a set of checkers (跳棋) .Three months later,he saw the checkers set at his friend Jerry's house. When Jerry was 6 years old,his father had died and his mother had lost her job,so he had few gifts.

The next Christmas,when the boy thought about how much fun he had watching Jerry play with the checkers,he told his mother that he wanted to put his new football in the Salvation Army box. Through giving gifts,he found that giving brings happiness not only to others but also to himself.

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

9. This issue is becoming for more and more people,especially for parents and experts in education (matter)

这一问题已被越来越多的人所关注，尤其是父母和教育专家。

6. Everything in the house the thorough cleaning.(upside)

由于进行大扫除,屋里的一切被弄得乱七八糟。
