Since the 1970s, scientists have been searching for ways to connect the brain with computers. Braincomputer interface(BCI) technology could help people with disabilities send commands to machines.

Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show 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 body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”

The scientists 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 finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell 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 finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. 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 get advantages from. And the other is sure that they can use the technology for long.

1.BCI is a technology that can________.

A. help to make computer systems more modern

B. connect the human brain with computers

C. help the disabled to be healthier

D. control a person’s thoughts

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 money 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 Sickness

I love my Blackberry mobile phone – it’s my little connection to the larger world that can go anywhere with me. I also love my computer, as it holds all of my writing and thoughts. However, I know there are times when I need to move away from these things and truly communicate with others.

I teach a course called History Matters in college. My goals for the class include a deep discussion of historical subjects and ideas. Because I want students to fully study the material and discuss with each other in the classroom, I have a rule – no computers, iPads, phones, etc. When students were told my rule, some of them were not happy.

Most students think my reasons for this rule include negative experiences in the past when students made wrong use of technology. There’s a bit of truth to that. I’ve seldom had students make wrong use of technology in my classes; however, I have been e-mailed by students while they were in other teachers’ classrooms.

Some students think that I am anti-technology. There’s no truth in that at all. As I noted above, I love technology and try to keep up with it.

The real reason why I ask students to leave technology at the door is I think there are very few places in which we can have deep conversations. Interruptions (中断) by technology often break students’ thoughts and make them depend too much on outside information for ideas. I want students to dig deep in themselves for ideas. I want them to push each other to think differently and to make connections between the course material and the class discussion.

I have been teaching my history class in this way for many years and the evaluations (评价) show student satisfaction with the environment that I create. Students realize with deep conversation and difficult tasks, they learn at a deeper level – a level that helps them keep the course material beyond the classroom.

I am not saying that I won’t ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I will continue my plan. A few hours of technology-free dialogue is just too sweet to give up.

1.The writer’s rule for his History Matters class is ____.

A.discussing historical ideas deeply

B.studying and discussing the materials

C.leaving technology out of the classroom

D.making right use of technology in class

2.The word “negative” in Paragraph 3 means ____.

A.similar B.unforgettable C.special D.unpleasant

3.What can we infer from the passage?

A.Students make right use of technology in other teachers’ classes.

B.The classroom is one of the good places to have deep conversations.

C.The writer encourages students to agree with others after discussion.

D.Students are unhappy with the writer’s way of teaching history.

4.The writer wants to tell us that ____.

A.technology has different influences in different classes in college

B.technology makes it difficult to have true communication in class

C.history classes can help students to develop their deep thinking

D.it is time for him to give up his teaching method in history class

Our smart phones are amazing, but our connections can be so slow. The future in science-fiction movies seems so close, yet so far away. 5G technology makes that future look easily achievable. What is 5G? It’s the latest generation of cellular (蜂窝状的) network technology. It is faster and more stable (稳定的) than 4G. This powerful wireless network will change the way we live.

Transportation

With the introduction of 5G and smart technology, traffic lights, buses and even cars begin to communicate with each other. We will be able to check traffic flow so that traffic jams (拥堵) may soon become a thing of the past. Moreover, it’s reported there is a good possibility of seeing driverless cars on our roads. With the help of 5G, these cars will be able to react to sudden changes in their environment at once, such as a dog running across the road.

Medical treatment

With 5G networking, all the people can have the chance to use top medical resources. Before treatment, 5G will support video calls with doctors and provide advice for those who can’t visit a hospital at once. After being treated, wearable tech will send information to doctors in no time, allowing hospitals to monitor the patients from their homes. It also allows surgeons to perform operations remotely, using robots. In March, 2019, China completed its first 5G-based human brain surgery between a doctor and a patient located more than 4,000 kilometers away. Five months later, robots guided by Beijing doctors completed a test operation in three different locations at the same time!

It seems that 5G will make our life more exciting and convenient wherever we use it.

Title: 5G Makes a Great Difference

Since the 1970s, scientists have been searching for ways to connect our brain with computers. Brain-Computer Interface (BCI) technology could help people with disabilities send commands(指令)to machines.

Recently two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne. Switzerland, showed us a small robotic wheelchair directed（指挥）by a person’s thoughts.

In the laboratory. Tavella operated the wheelchair just by thinking about moving his left or right hand “Our brain has billions of cells（细胞）. These send signals（信号）through the spinal cord（脊髓）to the muscles（肌肉）to give us the ability to move. But some injuries or other conditions can stop these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with outside world by controlling the machines with thoughts.”

The researchers designed a special cap for the user. It picks up the signals from our brain and sends them to a computer. The computer gets the signals and starts to command the wheelchair after a short while.

Prof. Millan, the team leader, says scientists keep improving the computer software that gets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling machines. One example is this wheelchair.”

He says his team has set a main goal. That is to test with real patients, so as to prove that this is such a technology they can benefit（获益）from.

1.BCI is a technology that can __________.

A. help the disabled to be healthy again　　 B. help to improve computers

C. control a person’s thoughts　　 D. connect human brain with computers

2.Which of the following shows the right path（途径）of the signals described in Paragraph 4?

A. brain→computer→cap→wheelchair　　 B. computer→cap→brain→wheelchair

C. cap→omputer→brain→wheelchair　　 D. brain→cap→computer→wheelchair

3.Prof. Millan’s team will test their products with real patients to __________.

A. make them live longer　　 B. prove that the technology is useful to them

C. learn about their physical conditions　　 D. have a better understanding of computers

4.The best title of this passage might be __________.
