Question

【題目】閱讀理解。

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(頭皮) 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.

A．scalp→computer→cap→wheelchair

B．computer→cap→scalp→wheelchair

C．scalp→cap→computer→wheelchair

D．cap→computer→scalp→wheelchair

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

試題分析：

【1】細(xì)節(jié)理解題。根據(jù)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，在實(shí)驗(yàn)室，Tavella通過大腦里移動(dòng)他的左右手的想法就能操作這個(gè)輪椅。他甚至還能一邊看著輪椅并用他的思想指示輪椅，一邊和別人交談。因此Tavella是利用自己的思想來操作輪椅的。故選D。

【2】細(xì)節(jié)理解題。根據(jù)第五段內(nèi)容“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 interprets the signals and commands the motorized wheelchair...”可知，研究人員為用戶設(shè)計(jì)了一種特殊的帽子，它會(huì)接收來自頭皮的信號(hào)并將其傳給電腦。電腦會(huì)解讀這些信號(hào)，并指揮機(jī)動(dòng)輪椅。故選C。

【3】細(xì)節(jié)理解題。根據(jù)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，在病人身上進(jìn)行實(shí)驗(yàn)是他們團(tuán)隊(duì)工作的一個(gè)目標(biāo)，以便證明這項(xiàng)技術(shù)對(duì)廣大病人有用。故選B。

【4】標(biāo)題概括題。根據(jù)第一段內(nèi)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.”及下文介紹的最近的一項(xiàng)新發(fā)明可知，本文開篇點(diǎn)題，介紹了科學(xué)家研究的新技術(shù)BCI對(duì)殘疾人大有裨益。故選C。
