听力原文： (33)Researchers report that doing two or more things at once may decrease efficiency and actually take extra time switching from one task to another. In the most severe cases, it can even mean the difference between life and death.

In the study, four groups of young adults carried out a series of tasks and switched between different tasks, some complicated, such as solving math problems, and some more familiar, such as identifying geometric shapes. (34)The researchers found that time was lost in just switching from one task to another, and that time costs increased with the complexity of the tasks. “For each aspect of human performance—perceiving, thinking and acting people have specific mental resources whose effective use requires supervision through executive mental control,” said the lead author, David Meyer in materials provided with the report.

So-called“ multitasking” is becoming increasingly common because of cell phones and computers. the researchers point out, but it may just be adding wasted time and inefficiency to our days. A mere half second of time lost to task switching can mean the difference between life and death for a driver using a cell phone, Meyer said. (35)The authors say the research should make employers and employees think twice before implementing multitasking.

(30)

A．Multitasking is inefficient and wastes time.

B．Multitasking is a matter of life and death.

C．Multitasking is the process of executive control.

D．Multitasking is becoming increasingly common.

听力原文：Tears keep your eyes wet and they also contain substance that kills certain bacte

听力原文： Tears keep your eyes wet and they also contain substance that kills certain bacteria so it can't infect your eyes. Give up your tears and you lose this on-the-spot defense. Another thing you couldn't do without your tears is cry from joy, anger or sadness. Humans are the only animals that produce tears hi response to emotions. And most people say a good cry makes them feel better. That has led many scientists to believe that crying is an adaptive response to stress, that it somehow helps us cope with emotional situations. Tear researcher William Frey is trying to find out how it happens.

"One possibility," be says, "is that tears discharge certain chemicals from your body, chemicals that build up during stress. When people talk about crying it out, I think that might actually be what they are doing." He says. If Frey is right, how do you think not crying affects those who tend to "hold it in"？ Boys, for example, cry only about a quarter as often as girls once they reach their teenage years. And we all cry a lot less now than we did as babies. Could It possibly be that we face less stress？ Maybe we've found other ways to deal with it. Or maybe we just feel embarrassed.

(33)

A．To keep your eyes a bit drier.

B．To protect your eyes from infection,

C．To cry for your sadness only.

D．To conceal your happiness.

听力原文： Have you ever felt your mind got confused after a sleepless night？ You couldn't come up with an original thought no matter how hard you tried.

You were probably right if you thought that was caused by a lack of sleep. Dr. Home, a sleep researcher in England, studied 24 college students divided into two groups. One group got their normal eight hours of sleep. The other group didn't get the smallest amount of sleep--they stayed awake all night. The next day, Dr. Home tested the students. He asked them questions that required creative and original thinking. One of the questions was "How many uses can a cardboard box be put to？"

The results？ The wide-awake students did well on the tests. The tired students did poorly.

Research has already shown that tired people can do okay on tests of routine thinking, like simple addition. But Dr. Home tested creative thinking only.

As part of his study, he offered an amount of money as a reward to the sleepy students if they did well. But even this encouragement wasn't enough to help the students overcome their tiredness. They still did poorly. Dr. Home believes that the cerebral cortex--the part of the brain where thinking takes place--may get worn out during waking hours. Sleep may help to repair the brain overnight. "Without any sleep," he emphasizes, "even if you concentrate harder, you cannot do better." This study gives people something to think about, especially people like hospital workers and airline pilots, who must stay awake all night and then make emergency decisions.

(33)

A．The lack of sleep.

B．The difficult question.

C．The requirement of your creative thinking.

D．The requirement of your original thinking.

听力原文：M: So how come you chose psychology？W: Well, at lust I didn't have any clear idea

听力原文：M: So how come you chose psychology？

W: Well, at lust I didn't have any clear idea of what I wanted to do after university, I didn't say to myself "I want to be a clinical psychologist or a researcher or anything like that". I suppose I have just always been interested in people and the way they act.

M: And what was the course like？

W: It was just great. The teachers were all really friendly and they had this special approach to teaching. The whole course was based on a problem-solving approach.

M: I see from your CV that you graduated in 1997 and after that, let me see...

W: I got a job with the department of employment. It was only a temporary thing for about six months. I used to have to design questionnaires and things like that for surveys that they carried out. And I guess the psychology course at college helped me a lot.

M: So why did you leave？

W: Well, four years is a long time to be asking people questions. You know those sorts of questions about washing powder and shampoo. After two years of doing that I felt that while I could do it well, now I want to do something else that's a little different. It just wasn't challenging for me any more and because I needed a challenge I decided to move when I heard about the position of Senior Researcher here at institute I knew that's exactly what I want.

(23)

A．Be a researcher in the area.

B．Be a clinical psychologist.

C．Know how to be a problem-solver.

D．Know more about people's behavior.
