But when the bell for the next class rings, you can’t believe how 36 time has passed. If you are 37 with this scene, you’ll know how time flies when you are having fun and 38 when you are bored. Now scientists have 39 a reason why this is the case. Scans have shown that patterns of activity in the brain 40 according to how we focus on a task. When we are 41 , we concentrate more on how time is passing. And 42 makes our brains think the clock is ticking more slowly. In an experiment 43 by a French laboratory, 12 volunteers watched an image 44 researchers monitored their brain activity. The volunteers were told to 45 concentrate on how long an image appeared for, then 46 the color of the image, and thirdly, study both duration and color. The results showed that 47 was more active when the volunteers paid attention to 48 subjects. It is thought 49 if the brain is focusing on many aspects of a task, it has to 50 its resources, and pays less attention to the clock. 51 , time passes without us really 52 it, and seems to go quickly. If the brain is not so active, it concentrates its 53 energies on monitoring the passing of time. 54 , time seems to drag. Next time you feel bored 55 , perhaps you should pay more attention to what the teacher is saying!
