Up to 65% of children don't get as much sleep...

Up to 65% of children don't get as much sleep as they should do, and this can make them nervous and slower at school, scientists say.

So how long should young people sleep each night?　 The answer is between eight and ten hours. If you don't get enough sleep at night, you'll have less energy the next day.

①But the scientists say many children have missed out on 4, 500 hours of sleep by the time they are seven years old. They say that children miss sleep because they have TVs and computers in their rooms，and busy parents don't read to their younger children at night any more. The traditional "bedtime story" helps children to relax and fall asleep peacefully. Children with TVs and computers in their bedrooms are more likely to sleep badly, and to get less than eight hours' sleep. Even losing one hour's sleep a night can mean that children do less well at school.

German scientists think that your brain(大脑)keeps working while you are asleep.②To show that they were right，they gave two groups of people a problem to work out. One group went to sleep, and the other group stayed awake. The result? The people who slept worked out the answer

more quickly. This showed that their brains had been trying to find the answer while the people were asleep. So, make sure you get enough sleep tonight, and you'll be at your best tonight, and you'll be at your best tomorrow!

Millions of children around the world don’t have chances to get basic education, such as reading, writing andmathematics, and the problem is only getting worse. The United Nations Educational, Scientific and Cultural Organization, or UNESCO, reports that 263 million children around the world are not in school. Teaching these boys and girls is a problem that researchers are trying to solve.

The Global Learning XPrize competition is looking for ways to help children teach themselves　 with only a tablet computer（平板电脑）. What’s more, they are offering $15 million to find the best educational apps. In this way they can teach simple skills to people who have never attended school.

Keller told reporters that the plan is different from other ideas of education. “Traditional ways are mainly about building new schools and training new teachers,” he said. “There are many children who do not go to school. Can you develop something that’s so special and useful that you just give it to a child who cannot read in a very faraway part of the world　 – she picks it up, she touches it and she begins to learn how to read? And that’s the challenge that we put out to the world.”

About 200 teams entered the competition. And five teams of them were chosen. Each was given $1 million. The next step for these five teams is to field test their solutions. Google has given away 8,000 Pixel C tablets to children in 150 villages in the Tanga region of Tanzania. They will field test each team’s software in a period of 15 months. Whichever solution shows the highest achievement after that time will be the winner, receiving a prize of $10 million.

In America, most people don’t get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can’t sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children.

In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child’s behavior.

Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention.

The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children’s behavior at school. “In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference,” says Gruber.

1. Scientists worry that_______ may cause children to sleep less.

A. too much homework

B. pressure from parents

C. TV and computer games

D. parents’ bad sleeping habits

2. Scientists did the new study in order to know_______.

A. why children can’t get enough sleep

B. how long children should sleep every night

C. what children like to do before they go to sleep

D. if the amount of sleep can affect a child’s behavior

3. Who helped do some new study, children with less sleep_______.

A. Teachers.             B. Parents.             C. Scientists.             D. Psychologists.

4.According to the new study, children with less sleep_______.

A. were more likely to feel excited

B. were more active in playing games

C. had more problems paying attention

D. didn’t want to answer questions in class

5.The new study was done in_______.

A. a laboratory                             B. a classroom

C. a children’s club                         D. the children’s homes

Should Children Be Allowed to Get Bored?

Children need time to stand and stare. They should be allowed to get bored to that they can develop their ability to be creative.

Children are expected by their parents to be reading a textbook all the time. However, research shows that it may hamper the development of their imagination, while boredom can give them opportunities to develop creativity.

Boredom is often linked with loneliness, but a writer named Meera Syal said boredom had helped here in developing her mind. She told researchers about her childhood. Having few things todo, Syal often talked with her neighbors. She also tried to do things like learning to bake cakes. “But importantly, I Thought and wrote a lot, because I was bored,” Syal said. She kept a diary, filling here time with short stories and poems she made up.

Grayson Perry, an artist, grew up in a family with little money. He enjoyed himself by making up stories, drawing pictures for his stories and reading many books in the library. Bored but free, he spent hours looking out of the window, watching the changing clouds and seasons. Perry filled up his free time with what he liked. He became creative, because he could think freely.

Dr. Belton is an expert on the effects of emotions on learning. “Boredom could be an uncomfortable feeling,” she said. “But some young people cannot deal with that boredom creatively. So sometimes they may break a classroom window, or drive a car out for a mad race.”

Usually, when children have nothing to do, they would turn on the TV, the computer, or the phone. Their time on these things has increased, yet they need to have time to think about their experiences through play or just watching the world around them.

It is this kind of thinking that can inspire the imagination. On the other hand, the TV or phone may cut short the thinking process. That can be harmful to the development of creativity. “For developing the ability to be creative,” Dr. Belton advised, “perhaps we need to stand and stare, and stay off-line from time to time.”

1. What does the word “hamper” in Paragraph 2 probably mean?

A. Slow down.　　 　　　　　　　 B. Keep up with.

C. Go beyond.　　 　　　　　　　 D. Give rise to.

2. The writer talks about Syal and Perry to 　　　 .

A. stress the great differences between them

B. introduce a popular writer and a famous artist

C. suggest good ways of going through boredom

D. show effects of boredom on developing creativity

3. What can we learn from the passage?

A. Boredom provides children with space to think freely.

B. It’s much better for children to be busy than be bored.

C. Boredom helps children deal with difficulties properly.

D. It’s boring for children to think about their experiences.
