【题目】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 orders to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, showed 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 wheelchair and guided it with his thoughts.

“Our brain has billions of nerve cells(神经细胞). These send signals through the spinal cord (脊髓)to the muscles(肌肉) 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 outside world and also to control the machine.”

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 understands the signals and directs the motorized wheelchair. The wheelchair also has two cameras that recognize objects in its path. They help the computer react to orders from the brain.

Prof. Millan, the team leader, says scientists keep improving the computer software that understands brain signals and turns them into simple orders. “The practical possibilities that BCI technology offers to disabled people can be divided into two kinds: communication, and controlling the machine. 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 ensure that they can use the technology over long periods of time.

【1BCI is a technology that can ______.

A. help to update computer systems

B. link the human brain with computers

C. help the disabled to become well

D. control a person's thoughts

【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.

【3Which of the following shows the path of the signals described in Paragraph 5?

A. scalp computer cap →wheelchair

B. compute cap scalp →wheelchair

C. scalp cap computer →wheelchair

D. cap computer scalp →wheelchair

【4】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

【5】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. Computer Technology Could Help to Cure Brain Injuries

【题目】I ran into a local store today to pick up a few things. With an important meeting to attend, I was in a hurry , so I didn’t take a cart (手推车) on my way inside. As I walked between the shelves in the store, I passed by a young couple and their baby. I continued going through the store, picked up a few items I needed and ended up standing behind this couple in the checkout line.

While waiting, I noticed that the young father was holding his money tightly and nervously. The young mother was carrying a baby in her arms and asked the cashier (收银员) for a job application.

When the total was rung up, they had to pick items out of their cart because they didn’t have enough money. But all their items were basic necessities(必需品) that they needed most. It just broke my heart to watch the couple try to think about what they could do without. However, they were able to whittle down their items and paid the bill with the money that they had.

After they left, I quietly asked the cashier to add those items to mine. The cashier rang everything up, and then got me a shopping cart. We put in their items and I hurried over to their car. This is for you, I told them.

The young father just looked at me with such appreciation and thanked me. I will never forget the expression in his eyes. As I was getting into my car, they drove over. The young mother said, Miss, thank you so much.

Tears welled up in my eyes---as they are again now, while I write this. You are so welcome. Pay it forward some day, I replied.
