Question

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 hand. 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(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 make sure that they can use the technology over long periods of time.

解析試題分析：本文是一則新聞報(bào)道，科學(xué)家尋找到了一種方法，把人腦與電腦連接起來(lái)，進(jìn)而發(fā)明了Brain-computer interface(BCI)技術(shù)的發(fā)明，文中介紹了它的原理和對(duì)殘疾人帶來(lái)的益處。
【小題1】細(xì)節(jié)理解題。根據(jù)Since the 1970s, scientists have been searching for ways to link the brain with computers. 故選B。
【小題2】細(xì)節(jié)理解題。根據(jù)第二段“Tavella operated the wheelchair just by thinking about moving his left or right band.”。故選D。
【小題3】細(xì)節(jié)理解題。根據(jù)第五段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. 故選C。
【小題4】細(xì)節(jié)理解題。根據(jù)最后一段“to prove that this is a technology they can benefit from.”，證明他們可以從中獲得的好處。故選B。
【小題5】主旨大意題。本文是新聞文體，因此要關(guān)注首段的中心，由首段的第二句話“Brain-computer interface(BCI) technology could help people with disabilities send commands to machines.”由此推斷選C。
考點(diǎn)：新聞報(bào)道類(lèi)短文閱讀。
點(diǎn)評(píng)：在解主旨大意題時(shí)，要站在整篇文章的高度分析問(wèn)題，切忌犯以偏概全、以點(diǎn)代面的錯(cuò)誤。文章的標(biāo)題是段落中心思想最精煉的表達(dá)形式，它的特點(diǎn)是：短小精煉，涵蓋性強(qiáng)，一般要求能覆蓋全文，其確定的范圍要恰當(dāng)，既不能太大，也不能太小。
