Question

【题目】阅读理解。

Since the 1970s, scientists have been searching for ways to link the brain with computers.Braincomputer 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 hand. He could even talk as he watched the vehicle and guided it with his thoughts.

“Our brain has billions of nerve cells. 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 from.And the other is to guarantee that they can use the technology over long periods of time.

【1】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.

【2】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→computer→scalp→wheelchair

【3】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

【4】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

Answer 1

【答案】

【1】D

【2】C

【3】B

【4】C

【解析】

试题分析：

【1】细节理解题。根据第三段“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 vehicle and guided it with his thoughts.”可知，在实验室，Tavella通过大脑里移动他的左右手的想法就能操作这个轮椅。他甚至还能一边看着轮椅并用他的思想指示轮椅，一边和别人交谈。因此Tavella是利用自己的思想来操作轮椅的。故选D。

【2】细节理解题。根据第五段内容“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...”可知，研究人员为用户设计了一种特殊的帽子，它会接收来自头皮的信号并将其传给电脑。电脑会解读这些信号，并指挥机动轮椅。故选C。

【3】细节理解题。根据最后一段第二句“One is testing with real patients，so as to prove that this is a technology they can benefit from.”可知，在病人身上进行实验是他们团队工作的一个目标，以便证明这项技术对广大病人有用。故选B。

【4】标题概括题。根据第一段内容“Since the 1970s，scientists have been searching for ways to link the brain with computers.Braincomputer interface(BCI)technology could help people with disabilities send commands to machines.”及下文介绍的最近的一项新发明可知，本文开篇点题，介绍了科学家研究的新技术BCI对残疾人大有裨益。故选C。
