A study of sleep in sparrows suggests the relationship between sleep and the ability to learn may be more complicated (复杂) than realized.

Niels C. Rattenborg of the University of Wisconsin—Madison wanted to find out how the sparrows were able to deal with getting so much less sleep.He and his team brought eight wild birds into a lab and watched them for one year.They invented a game to check how well the birds could learn.In the game, the sparrows had to peck (啄) three buttons (按钮) in a certain order to get a food treat.The scientists discovered that the birds' ability to learn the right button order depended on (依靠) two things, the time of year and the

amount of sleep the birds had had.

During the migration (迁徙) season, the sparrows were restless at night and got much less sleep than usual.Even so, they were able to understand how to get the food quickly as if they'd had a regular night of sleep.Outside the migration season, they found the sparrows that got less sleep than usual had much more difficulty learning how to get the food treats than birds that had a regular sleep.

The results show that the sparrows can deal with much less sleep during the migration season than usual.If scientists can find out why, they may learn from sparrows and find ways of helping people deal with getting much less sleep.Until scientists fully understand the relationship between sleep and learning, it's better to get plenty of sleep when preparing for an exam.

1.Why can sparrows deal with much less sleep during the migration season?

A. They eat more.

B. The climate is better.

C. They find enough food.

D. Scientists still don't know it.

2.What can we infer from the passage?

A. When tired, you should try to focus (聚焦) on your study.

B. You should get enough sleep before an exam.

C. You should migrate like sparrows.

D. You should sleep less at night.

3.What would be the best title for the passage?

A. Sleep lessons from sparrows

B. How to get good exam results

C. How sparrows get a food treat

D. Sparrows' migration
