　　You have waited 40 minutes for the valuable 10 minutes’ break between classes．But when the bell for the next class rings, you can’t 　1　　 how quickly time has passed．

　　If you are familiar with this 　　2　　, you’ll know how time flies when you are having fun-and 　　3　　 when you are bored．Now scientists have 　　4　　 a reason why this is the case．

　　Scans have shown that patterns of activity in the brain 　　5　　 according to how we focus on a task．When we are 　　6　　, we concentrate more on how time is passing．And this makes our brains 　　7　　 the clock is ticking more slowly．

　　In an experiment 　　8　　 by a French laboratory, 12 volunteers watched an image 　　9　　 researchers monitored their brain activity．

　　The volunteers were told to 　　10　　 concentrate on how long an image appeared for, then 　　11　　 the color of the image, and thirdly, study both duration and color．The results showed that 　　12　　 was more active when the volunteers paid 　　13　　 subjects．

　　It is thought that if the brain is 　　14　　 focusing on many aspects of a task, it has to 　　15　　 its resources, and pays less attention to the clock．　　16　　, time passes without us really 　　17　　 it, and seems to go quickly．If the brain is not so active, it concentrates its 　　18　　 energies on monitoring the passing of time．　　19　　, time seems to drag．

　　Next time you feel bored 　　20　　, perhaps you should pay more attention to what the teacher is saying!
