Question

You have waited 45 minutes for the valuable 10 minutes’ break. But when the bell for the next class rings, you can’t believe how quickly time has passed. If you have this experience, you’ll know how time flies when you are having fun and drags when you are bored. Now scientists have come up with a reason why this happens.

They have found that the brain changes its way to work according to our attention to a task. When we are bored, we pay more attention to how time is passing. And this makes our brains think the clock is ticking more slowly.

Recently some researchers who went to understand the conditions carried out an experiment. In the experiment, twelve volunteers watched a picture while researchers monitored( 关注) their brain activity.

      The volunteers were told to first notice how long a picture appeared, then the color of the picture, and third1y, study the both. The results showed that the brain was more active when the vo1unteers paid attention to more subjects.

      It is thought that if the brain is busy noticing many aspect(方面) of a task, it has to spread its resources, and pays less attention to the clock. Therefore, time seems to go quickly. If the brain is not so active, it spends its full energy on the passing of time. As a result, time seems to move slowly.

     D. The brain changes its way to work according to our attention to a task.

73. How did the researchers do the experiment?

      A. By inviting the volunteers to have a long class.

B. By asking the volunteers to pay attention to a clock.

C. By monitoring brain activity while volunteers are watching a picture.

D. By asking ten volunteers to watch a picture.

74. Which of the following is TRUE according to the passage?

      A. Time seems to go quickly if we’re busy.

B. If we pay more attention to the clock, we may feel less bored.

      C. Time goes slowly when the brain is active.

      D. If we spend full energy on the clock, time goes quickly.

75. Which is the best title of the passage?
