80% of teens don't get enough exercise
The World Health Organization (WHO) says that 80% of the world's teens don't get enough exercise to live healthy lives. The report, which was published in the Lancet, was based on research done with students aged 11-17 in 146 different countries. The WHO has been studying teen activity levels since 2001 and reports that not much has changed since then.
The WHO says that kids should get at least an hour of medium to hard exercise every day. This could include walking, running, biking, dancing, playing sports, or many other activities.
More and more research is showing that exercise doesn't just help the body, it can help the brain, too, improving thinking, test scores, and school grades.
One big reason for the lack (不足) of activity in today's teens is technology, such as smartphones, computers, and TVs. Many teens find it very hard for them to pull themselves away from their devices (设备), whether they are texting, playing games, or watching videos or movies. The WHO warns that young people need to do less playing in the digital (数码的) world, and more playing in the real world.
Health experts want schools and families to encourage teens to be more active. Teens should take part in sports, whether on official teams or just playing around in the playground.
Experts believe that it's very important for young people to fall into these habits now, because the positive effects (积极影响) of those habits can carry on into adult (成年的) life. Studies show that the best way to tell how active someone will be as an adult is to look at how active he was as a teen.

Researchers say that nearly two thirds of children don't get enough sleep, and this can make them nervous and slower at school. So how long should young people sleep each night? The answer is between 8 and 10 hours. If you don't get enough sleep at night, you'll have less energy the next day.
A report shows that children sleep less 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 were 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 worse than usual at school.
British scientists think that your brain keeps working while you're asleep. To show that they were right, they have done an experiment. They gave two groups of people a problem to work out. One group went to sleep, and the other group stayed awake. You want to know the result? The people who slept worked out the answer more quickly. Researchers explained that their brains were 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 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.

According to a recent survey, British teenagers are damaging(伤害) their health by not getting enough sleep because they are prevented from doing so by electronic gadgets (电子设备) in their bedrooms.
According to the Sleep Council, "junk sleep" could compete with eating unhealthy junk food as a main worrying lifestyle for parents of teenage children.
Among the l, 000 students aged 12 t0 16 who were tested in the survey, 30 percent just slept for 4 to 7 hours a day. Almost a quarter said they fell asleep, more than once a week, while watching TV, listening to music or using other electronic gadgets.
"This is a quite worrying trend(潮流)”, said Dr Chris Idzikowski of the Edinburgh Sleep Centre. "What we are seeing is the appearance of terrible junk sleep - sleep that is of neither the length(长度) nor the quality it should be."
Nearly each of the teenagers had a phone, music system or TV in his or her bedroom, with around two-thirds owning all three. Almost one in five of the teenage boys said the quality of their sleep had been influenced by leaving their TVs or computers on. The survey also found that 40 percent of youngsters felt tired each day, with girls aged 15 to 16 feeling the worst.
"Teenagers need to wake up to the fact that to perform(表现) well. They need to do something about their sleep. I'm shocked(震惊) that so few teenagers have noticed the close connection," said Idzikowski.
1.Among the students tested in the survey, about_______ of them fell asleep while using their electronic gadgets.
A. 200 B. 250 C. 300 D. 400
2.Which of the following kinds of sleep is thought to be "junk sleep"?
A. A long sleep of good quality.
B. A short but good sleep.
C. A sleep with many dreams.
D. A short sleep of low quality.

Beyond its influence on health, not getting enough sleep can lead to car accidents or other mistakes. Here are what sleep researchers have found about how to sleep.
How much sleep do we actually need?
It is known that all of us naturally need no less than eight hours of sleep per night. When we sleep below six hours per 24, we’re at an increased risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Sadly, there is no storage(储存) system for sleep in the brain.
Can we train ourselves to need less sleep?
As a study in 1964, a 17-year-old boy named Randy Garden stayed awake for 264 hours. How many people could do anything close to that without dying?
When you are reading this, you might say you usually get six hours of sleep and feel just fine. Sleep experts often compare people without enough sleep to drunk drivers: They don’t get behind the wheel thinking they’re probably going to kill someone.
Can we drink coffee instead of sleeping?
Coffee can keep us awake. Remember, too much coffee may throw off our sleep and energy cycles. So reduce coffee and avoid caffeine for four to six hours before bedtime.
Does a sense of purpose connect to sleep quality?
A new research suggests a kind of strong connection between purpose in life and sleep. People who have a greater sense of purpose usually have better physical and mental health, which in turn explains their higher-quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.

People around the world need to get moving, according to a new study by the World Health Organization (WHO).
About 25 percent of adults worldwide do not get enough exercise, according to the study. 1. Because of this, about 1.4 billion people are at greater risk for deadly diseases such as heart disease and cancer. According to the WHO, people should do at least 150 minutes of light exercise each week, such as dancing or swimming. 2.
