There have been three periods in the history of post-war broadcast interviewing. The first, "the age of respect", when it was an honour to have you, the interviewee, on the programme, lasted until the middle 50s. The second, "the age of supremacy", when politicians in particular looked upon the interviewers as rivals who made them feel uncomfortable by their knowledge and rigour of questioning, came to an end at the beginning of this decade. Now we are in "the age of evasion", when most prominent interviewees have acquired the art of seeming to answer a question whilst bypassing its essential thrust.

Why should this be? From the complexity of causes responsible for the present commonplace interview form, a few are worth singling out, such as the revolt against rationality and the worship of feeling in its place. To the young of the 60s, the painstaking search for understanding of a given political problem may have appeared less fruitful and satisfying than the free expression of emotion which the same problem generated. Sooner or later, broadcasting was bound to reflect this.

This bias against understanding has continued. To this we must add the professional causes that have played their part. The convention of the broadcast interview had undergone little change or radical development since its rise in the 50s. When a broadcasting form. ceases to develop, its practitioners tend to take it for granted and are likely to say "how" rather than ask "why".

Furthermore, these partly psychological, partly professional tendencies were greatly accelerated by the huge expansion of news and current affairs output over the last 15 years. When you had many, additional hours of current affairs broadcasting, interviewing turned out to be a far cheaper convention than straight reporting, which is costly in terms of permanent reporters and time preparation. The temptation to combine an expanded news and current affairs service with a relatively small additional financial expense by making the interview happen everywhere proved overwhelming.

To be fair, there are compensating virtues in interviewing, such as immediacy and authority, yet in all honesty I must say that the spread of the interviewing arrangement has led to a corresponding diminution of quality broadcasting.

According to the author, in the past politicians thought that television interviewers ______.

A．knew more about politics than they did

B．should be honoured to meet them

C．really were eager to be politicians too

D．gave them a difficult time in interviews

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 Milan 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 band. 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. Milan, 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.

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

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.

3. 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

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. Robotic Vehicles Could Help to Cure Brain Injuries
