A new study says the habit of sleeping in（睡懒觉）on weekends may not be such a good idea for your health.
36 healthy young men and women took part in the study. They were divided into three groups and were followed over 30 days.
The first group could sleep for nine hours each night for the 30 days. The second group had other only five hours of sleep every night. The third group had five hours on weekdays but was allowed to sleep as long as they wanted on the weekend. But on Monday, the third group was put back to the sleep schedule（周期）of only five hours a night.
The study showed that the first and the third groups ate more snacks after dinner and put on weight during the study, men much more than women.
What was surprising the scientists was the third group who slept in on weekends. "Even though people slept as much as they could, it was not enough," Dr. Wright said. "As soon as they went back to the short sleep schedules on Monday, the ability of their body to control blood sugar was badly affected." "Not only that, the result showed increased sensitivity to insulin（胰岛素）in both their muscles（肌肉）and their livers（肝脏）, the result wasn't found in other groups. The reason may be that their body clock had been changed.

2.How long did the third group sleep everyday？

A new research on students’ sleeping habits says that more than 70% of students do not get enough sleep.
Researchers found that primary school students get 9 hours and 10 minutes of sleep a night, junior high school students get 8 hours and 6 minutes, and senior high school students get 7 hours and 9 minutes. None of those hours are enough for each group. Not enough sleep can cause many kinds of problems in children and teenagers.
In 2007, Shanghai Municipal Education Commission asked primary and middle schools in the city to adjust their timetables so that students could get more sleep. Two years later, a research found that students at schools that adjusted their timetables got more sleep than in 2005.
The researchers hope that the government will take measures to make students have enough sleep. Students in other places may even less sleep than those in Shanghai.

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

Best Tool to Teach Baby Talk
A new study says electronic toys are not helping babies learn. The study’s writer is Professor Anna Sosa. She leads the Child Speech and Language Lab at Northern Arizona University. She said, “Even if companies say that their toys are educational, they’re not teaching the babies anything at this time.”
Anna Sosa and her team studied babies who were from 10 to 16 months old.
The scientists listened to recordings of parents playing with their babies. The children used electronic toys, traditional toys and books.
What they found is that parents talked less with their babies when the babies played with electronic toys. Sosa says that the parents also responded(反应) less and used fewer words when the babies played with electronic toys.
Why is this important?
She says research shows that how quickly children develop language often depended on what they hear from parents. When the babies played with electronic toys, parents said little to their children. Sosa says parents talked a lot more when the babies played with traditional toys. Parents would describe the toys, name them and tell about their colors and shapes, as their children played. Parents even gave more information as their babies looked at the pictures in books.
Sosa is not telling parents to throw out electronic toys. She believes that these electronic toys can provide entertainment(娱乐) for the babies. But parents should not look at such play as a learning experience.
Toy Industry Association spokeswoman Adrienne Appell responded to the study.
She said, “It is important that parents make time to play with their children. Playing is a way that kids can learn so much, not only learning skills, but social and developmental skills.” She added that play should be balanced, including time for just “make-believe” activities, as well as traditional and electronic toys.
