【题目】Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. 【1】 .

Some people blame(责备) the fact that we are surrounded (包围) by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. 2 , then probably children would buy less take-away food.

3 . I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If parents often give their children fried chicken and chocolate rather than healthy food, they will go for sweet and salty foods, and children will find it hard to get rid of the habit.

There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. 4 . What they need is to go outside and play active games or sports.

The above are the main reasons for this problem. 5 , as well as forcing them away from fast food shops and bad eating habits.

A. There is another argument that blames parents for allowing their children to become overweight

B. Adults are becoming fatter and unhealthier too

C. If there were fewer of these restaurants

D. Therefore we have to encourage young people to be more active

E. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food

F. I feel there are a number of reasons for this

G. It’s a good idea to allow children to eat what they choose

【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 commands to machines.

Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated 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 (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 over long periods of time.

1BCI is a technology that can ________.

A. help the disabled to recover

B. control a person's thoughts

C. help to update computer systems

D. link the human brain with computers

【2】How did Tavella operate the wheelchair in the laboratory?

A. By talking to the machine.

B. By controlling his muscles.

C. By using his mind.

D. By moving his hand.

【3】Which of the following would be the best title for the text?

A. Robotic Vehicles Could Help to Cure Brain Injuries

B. BCI Could Mean More Freedom for the Disabled

C. New Findings About How the Human Brain Works

D. Switzerland, the BCI Research Center
