Question

【題目】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 orders to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, showed 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 hand. He could even talk as he watched the wheelchair and guided it with his thoughts.

“Our brain has billions of nerve cells(神經(jīng)細胞). These send signals through the spinal cord (脊髓)to the muscles(肌肉) 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 outside world and also to control the machine.”

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

Prof. Millan, the team leader, says scientists keep improving the computer software that understands brain signals and turns them into simple orders. “The practical possibilities that BCI technology offers to disabled people can be divided into two kinds: communication, and controlling the machine. 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 from. And the other is to ensure 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 become well

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. compute → cap → scalp →wheelchair

C. scalp → cap → computer →wheelchair

D. cap → computer → 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. Computer Technology Could Help to Cure Brain Injuries

【4】B

【5】C

【解析】

試題分析：大腦能不能直接和電腦機器連接起來并控制？最近科學家們研究出一種“腦控輪椅”。病人戴上特定的帽子就可以通過思考和想法操控輪椅。也許這是一項福音。

【1】細節(jié)題。由“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.”可知BCI就是為了讓人腦來直接連接電腦并控制。故選B。

【2】細節(jié)題。由“In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.”可知，Tavella用移動左右手的想法來控制輪椅。故選D。

【3】細節(jié)題。由倒數(shù)第二段可知，信號從頭皮傳到帽子，再由電腦控制輪椅。故選C。

【4】細節(jié)題。根據(jù)最后一段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 from.可以知道選擇現(xiàn)實中的父母去接受測試是為了滿足他的團隊的兩個目標中的一個就是證明這個技術(shù)是否真正對他們有效。故選B。

【5】細節(jié)題。全文主要是在介紹BCI這一新發(fā)明并強調(diào)對殘疾病人的巨大幫助。故選C
