For some people, the sight of a mouse can be reason to scream. For other mice, the same sight can be reason to sing.

    Mice will probably   21   sing their way to any concert, but researchers in the United States have found   22   that mice do,   23  , sing.

    Scientists already knew that mice make ultrasonic(超聲波) sounds—noises that are too high-pitched(高音的) for people to hear   24   special equipment.

    To find out whether mice put such sounds together in song-like   25  , the researchers recorded the sounds of 1 mice. Using computer   26  , they were able to separate the sounds into specific types of syllables(音節(jié)), and found the mice produced about 10 syllables per second.

    The results showed that nearly all of the mice repeated sequences(順序) of syllables in different patterns. That’s enough to meet the definition of what scientists   27   song. But not all scientists are   28  _ that what the mice are doing is   29   singing. To prove it, the researchers must show that there’s learning involved. And, they need to __  30   why the mice sing.

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were   36   to show that we all have “a body clock”   37    us, which controls the   38   and fall of our body energies,   39   us different from one day one to the next.

The   40   of “a body clock” should not be too   41   since the lives of most living things are controlled   42   the 24 hour night-and-day cycle. We feel   43   and fall asleep at night and become   44   and energetic during the day. If the 24 hour-cycle is   45   , most people experience unpleasant   46   . For example, people who are not   47   to working at night can find that   48   of sleep causes them to   49   badly at work.

  50   the daily cycle of sleeping and   51  , we also have other cycles which   52   longer than one day. Most of us would   53   that we feel good on some days and not so good on    54   ; sometimes our ideas seem to flow and at other times, they   55   do not exist.

When someone steps on your toe by accident, you will hurt plenty．But it hurts even more, if you think the person does the same thing on purpose．Earlier studies have found that the feeling of pain can change with how it is experienced．That is why giving people sugar pills and saying they are medicine can make them feel better．

This study examined whether self-reported pain is indeed higher when the events producing the pain are understood as intentionally caused by another person．For the study, the researchers told 40 volunteers that they were going to do a series of tasks, including color matching, number counting and discomfort assessment．This last task involved their receiving a brief electric shock to the wrist．They were told that a partner, sitting in another room, would choose which task they would do, and a computer screen helped them to know their partner’s choice．

In some cases, the volunteers were told their partner had chosen the pain tolerance test．In others, they were told the computers would select the pain tolerance test regardless of their partner’s choice．When volunteers thought that their partners were making the shocks on them on purpose, the feeling made the pain worse．As a matter of fact, they were the same．

This study provides evidence that the experience of pain changes depending upon how they think when people have been harmed．Specifically, the meaning of a harm — whether it was intended — influences the amount of pain it causes．So, although a broken toe may hurt, an intentionally broken toe should hurt more．

It can be concluded from the text that _______．

A．the feeling of pain varies from one person to another k+s-5#u

    When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate（照亮）me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.

     When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say:“Let’s start with a train whistle today.” We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems stopped.

   When I lived for a time in London, I had a friend, He was in despair(失望)and I was in despair. But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. We gave London to each other.

     For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think:“Yes, I must tell….”We have never met.

    It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist（心理學(xué)家），who will only fill up the healing（愈合的）silence necessary to those darkest moments in which I would rather be my own best friend.
