(2016高考阅读理解)阅读下列短文,从每题所给的选项中选出最佳选项。

One windy spring day,I observed young people having fun using the wind to fly their kites.Multicolored creations of varying shapes and sizes filled the skies like beautiful birds dashing and dancing in the exciting atmosphere above the earth.As the strong winds gusted against the kites,a string kept them in check.

Instead of blowing away with the wind,they arose against it to achieve great heights.They shook and pulled,but the controlling string and the clumsy tail kept them in tow(牵引),facing upward and against the wind.As the kites struggled and trembled against the string,they seemed to say,“Let me go!Let me go!I want to be free!” They flew beautifully even as they fought the forced restriction of the string.Finally,one of the kites succeeded in breaking loose.“Free at last,” it seemed to say.“Free to fly with the wind.”

Yet freedom from control simply put it at the mercy of an unsympathetic gentle wind.It flew ungracefully to the ground and landed in a twisted mass of weeds and string against a dead bush.“Free at last”.Free to lie powerless in the dirt,to be blown helplessly along the ground,and to settle down lifeless against the first roadblock.

How much like kites we sometimes are.There always exist misfortunes and restrictions,rules to follow from which we can grow and gain strength.Prohibition is a necessary counterpart to the winds of opposition.Some of us pulled at the rules so hard that we never fly fast to reach the heights we might have obtained.If we keep all the commandment(戒律),we will never rise high enough to get our tails off the ground.

Let us each rise to the great heights,recognizing that some of the prohibitions are actually the steady force that helps us climb and achieve.

Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(BCI) 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 directed by a person’s thoughts.

In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with his thoughts.

“our brain has billions of nerve ceils. These 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 prevent 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 interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

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

1.BCI is a technology that can

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

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

2. 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.

3. Which of the following shows the path of the signals described in Paragraph 5?

A. scalp → computer →cap →wheelchair

B. computer →cap →scalp →wheelchair

C. scalp →cap →computer →wheelchair

D. cap → compute →scalp →wheelchair

4. 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

5. Which of the following would be the best title for the text?

A. Switzerland, the BCI Research Center

B. New Findings About How the Human Brain Works

C. BCI Could Mean More Freedom for the Disabled

D. Robotic Vehicles Could Help to Cure Brain Injuries

【文章大意】科普说明文。本文介绍了BCI脑机接口技术,它是帮助残疾人向机器输送指令。

【参考方案】1---5、BDCBC
