导学号 76234011 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(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
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 答案 B 解析 细节理解题。根据第一段可知,自 20 世纪 70 年代以来,科学家一直寻找能将人脑与电脑 相连的途径。BCI 技术能帮助残疾人向机器发送指令。故此处 B 项正确。而 C 项只是部分 正确,虽然 BCI 技术能帮助残疾人,但却不能帮他们康复。
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. 答案 D 解析 细节理解题。根据第三段可知 Tavella 只是想想动左右手就能操作这个轮椅,甚至当他 观察这台机器时就能进行交流,也能用他的思想指导机器人工作。因此机器人是在人脑的思 想支配下进行工作的。故 D 项正确。
3.Which of the following shows the path of the signals described in Paragraph 5?
D.cap→computer→scalp→wheelchair 答案 C 解析 细节理解题。根据第五段可知,首先研究人员为用户设计了一种特殊的帽子,它会捕捉头 皮发出的信号并将其传给电脑。电脑将这些信号进行分析翻译,给轮椅发出指令。机器人轮 椅装有两部摄像头能识别信号路径中的物体,从而帮助电脑对人脑的指令作出反应。故此处 C 项正确。
4.The team will test with real patients to
A.make profits from them
B.prove that the technology is useful to them
C.make them live longer
D.learn about their physical condition 答案 B 解析 推理判断题。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,在患者身上进行实验是他们团队工作的一个目标, 旨在证明这项技术对他们有益。故正确答案为 B 项。
Being angry doesn’t really solve much,but what people do when they feel angry is
important.The goal is to calm down and try to solve what is bothering you.This is hard for some
kids and adults,too.Instead of calming down,some kids might keep getting more and more upset
until they explode(爆发)like a volcano(火山)!
Their anger might be so strong that they lose control of their temper(脾气).They
may act in ways unacceptable and hurtful.People may say that someone has trouble controlling
Some kids might get so angry that they scream at their parents,break something,or even
worse,hit their brothers or sisters.4.
However,it’s not OK for a kid to do any of those
things.Kids don’t want to act in this way,but sometimes angry feelings can be hard to manage.So
what to do?
Well,the good news is that kids don’t just have to keep making the same mistakes over and
Imagine your temper as a puppy(小狗) inside you that needs some
training.The puppy is not bad—it will probably turn out a great dog.It just needs to learn some
rules because,right now,that puppy is causing some problems to you.
A.You can train your temper.
B.You don’t want to cause trouble.
C.Everybody gets angry sometimes.
D.Some kids get angry more often or more easily than some other kids.
E.Kids should be allowed to express their feelings,even angry ones.
F.In fact,they usually mean that a kid behaves badly when feeling angry.
G.Instead of thinking of the person you’re angry with,think of something else. 答案 1~5 CDFEA
