Maybe you should sit down before you read this. It's a little frightening. Your sitting may be killing you.
Health experts say the U.S. adult now sits about 6.5 hours a day. That is up about an hour a day compared to 2007. The news is even worse for teens. They sit eight hours each day. The information was put out by the National Center for Health Statistics. It has collected the numbers for the past 16 years. It is worried about what it has found.
Research shows that people who are not active can get sick. Their bones get weaker. They burn fewer calories (卡路里). That makes them more likely to put on too much weight. They might even get diabetes (糖尿病). They are at risk for high blood pressure and heart problems, too.
Some experts also think sitting too much can influence how your blood moves through your body and how well your body fights off illness. Being active helps in lots of ways. It can make you happier, burn more calories and give you more energy. It can also help you sleep better.
About 60% of people in the U.S. watch at least two hours of TV each day. That number has stayed about the same in recent years.
Computers are the biggest reason for more hours spent sitting. Computer use outside of work or school has gone up for all age groups. Now, 50% of adults spend at least an hour of their free time on a computer each day. That is up from 29% in 2003.
About 53% of teens now spend at least an hour of free time on computers. So do 56% of kids. As many as 1 in 4 people who use computers use one for three hours or more outside of work and school.
So get up, take some breaks and go outside. You might save your life by doing outdoor activities.

If you get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle (吹口哨)three times. Stop. Then shout or whistle three times again. Any signal(信号)for three times is a call for help.
Keep up shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house with branches(树枝. Make yourself a bed with leaves and grass.

"Sometimes I see a picture of some friends online, " explains Lucas 16. "They’re hanging out somewhere. I can’t go—maybe I have homework. But it makes me feel unhappy. My friends are having fun and I'm not."

For Grace, 21, her FOMO is a serious problem. "I never read or play sports now, " she explains. "I go out almost every night because I don't want to miss out. Or I sit at home and I read online about what my friends are doing. FOMO kills your interests in your spare time."
Dr. Suzanne Taylor, a psychologist(心理学家), says social networking website are not helping people with FOMO. "They're perfect for communicating with friends and relatives — all over the world. But they're full of pictures of your friends,doing exciting things. Suddenly, other people's lives look interesting and our own lives feel boring."
So how can we fight FOMO? Should we stop using social networks? "That isn't possible for many people,’’ says Dr. Taylor. "But before bed tonight, put your phone in another room. And before you go to sleep, think about the interesting things you're doing this week. And remember how lucky you are.’’
1.People with FOMO _____________.

阅读短文,从各题所给的选项中,选择最佳选项。
Are you nervous? Maybe you should sit in a blue room. Are you always cold? Maybe you should sit in a room painted in a “warm colour” such as soft orange. Are you often sad? Maybe you should sit in a yellow room. Some researchers believe that colour has the power to influence our feelings. They believe that colours affect (影响) everyone in the same way.
One study was in a workplace. The researchers painted heavy boxes white and light boxes black. They wanted to see how colour affected the workers’ feelings. Which boxes do you think were more difficult to lift? The heavy white ones? No. The white boxes were heavier but they looked light. The researchers think that this is because light colours seem light.
Another study was at school. Researchers at the University of Alberta in Edmonton, Canada, studied children with behaviour problems in their classroom. When the walls were brown and yellow, the children’s heart rate went up and they were over active. However, when the walls were dark blue, the children’s heart rate was slower and the children were much calmer. If this is true, we can think carefully about the colors around them-- not just in our homes, but also in offices, in schools, in hospitals, in gyms, in museums, in restaurants and even in prisons.
1.According to Paragraph 1, it’s better for a person who fails in the exam to sit in a room.

People are always trying to live a healthy life. You might have read so much on this topic. The following ideas may sound strange, but they can really help you.
Exercise when you are tired.
After a long and tiring day of study, exercising might not sound like a good idea, but it should. In fact, physical activities can provide you with the missing energy. Research shows that exercising for just 30 minutes can make you feel good!
Write by hand to help the brain be active.
Although writing something using a computer is faster. It is much better to remember the whole thing by writing it down by hand. When you read a handwritten text, naturally it's easier for your brains to remember the information.
Spare more time for yourself.
By sparing the time for yourself and just being alone for a while, you can have a chance to think and get to know yourself better. And you won't behave impulsively (冲动地).
Drink hot drinks on a hot day.
What cools more on a hot summer morning, cold water or hot water? The study shows that the hot water does make people feel cooler. When you are drinking something hot, the body will feel the change in temperature and increase the perspiration (流汗), which helps you cool down!
