March 21 has been declared World Sleep Day, a time to recognize and celebrate the value of sleep. Many sleep experts hope it will be a wake-up call.

According to a poll (民意调查）by the National Sleep Foundation, nearly 4 in 5 Americans don’t get as much sleep as they should during the workweek. On average, adults are thought to need at least eight hours of sleep a night, although some can manage with less and some won’t do well without more. But the survey found that, on workdays, only 21% of Americans actually get a full eight hours of sleep, and another 21% get less than six.

To many of us, the thought of spending more time sleeping is, well, a big yawn. On the other hand, the thought of being smarter, thinner, healthier and more cheerful has a certain appeal. And those are just a few of the advantages that can be ours if we consistently get enough sleep, researchers say. Also on the plus side: We’re likely to have better skin, better memories, better judgment, and, oh, yes, longer lives.

“When you lose even one hour of sleep for any reason, it influences your performance the next day,” says Dr. Alon Avidan, director of the UCLA Sleep Disorders Center.

A study published last year found the same to be true even of children. When kids aged 8 to 12 slept for just one hour less for four nights, they didn’t function as well during the day.

But sleeping has an image problem. “We see napping or sleeping as lazy,” says Jennifer Vriend, a clinical psychologist in Ottawa, Canada, and the leading author of the study with children. “We put so much emphasis on diet, nutrition and exercise. Sleep is in the back seat.”　 In fact, she adds, no matter how much we work out, no matter how well we eat, we can’t be in top physical shape unless we also get plenty of sleep.

March 21 is World Sleep Day. How’s your sleep recently?

The Chinese Medical Doctor Association asked 8,200 people in China about their sleep. More than 36.3 percent of them said they often sleep badly. The study also finds that many students have only 5 hours of sleep a day. According to the US National Sleep Foundation, teenagers need 8.5 to 9 hours of sleep every night.

What cuts into their sleeping time? Homework.　 Also, school starts early in the morning. But bad sleeping habits also play a role.

Do you like to have a look at your mobile phone before going to bed? The survey finds that 60 percent of people check their phones before they sleep. They read news, check their WeChat (微信)and micro blog messages, or chat with QQ friends.

It’s important for us to get enough sleep. If we can’t get enough sleep, we’ll feel sleepy and think slowly. And sleepy kids are often unhappy, says a study by the US National Foundation.

We can’t change our school time. But there are still ways to get better sleep. Stay away from soda, coffee and tea at night. They make it hard to sleep well. Leave your mobile phone and computer on your desk. Watch less TV.

Celebrating sleep

World Sleep Day, observed on 21 March, was created to bring attention to the growing number of sleep problems worldwide. Sleep is a natural part of human life, but many people in the modern world ignore its importance. As a result, sleep problems are increasingly common.

In 2002, scientists at the University of Athens in Greece conducted a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Of the people that responded to the survey, 24 percent said that they did not sleep well, and based on their responses, 31.6 percent were diagnosed (诊断)with insomnia（失眠）and another 17.5 percent were diagnosed with borderline insomnia. In addition, 30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.

Overall, the survey found that ninny people suffer the effects of poor quality sleep, some examples of which are being unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are pressure from school or work and a fast pace of life, but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep. The survey’s findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night. The short-term effects of this are tiredness and trouble concentrating. If this happens for a long time, the risk of putting on weight and having a heart attack may increase.

There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.

Getting a good night's sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.

Limiting kids' recreational(消遣) screen time to less than two hours a day, along with enough sleep and physical activity, is associated with improved cognition(认知), according to a study published in The Lancet Child & Adolescent Health.

The study included about 4,500 US children aged 8 to 11 and measured their habits against the Canadian 24-Hour Movement Guidelines for Children and Youth. It found that 51% of the children got the recommended(建议) nine to eleven hours of uninterrupted sleep per night, 37% met the recreational screen time limit of two hours or less per day, while 18% met the physical activity recommendation of at least 60 minutes of accumulated physical activity a day. Only 5% of the children in the study met all three recommendations; 30% met none at all.

The researchers found that as each recommendation was met by a participant, there was a positive association with global cognition, which includes memory, attention, processing speed and language. Those who met all three had the most "superior" global cognition, followed by those meeting the sleep and screen time recommendation and finally the screen time recommendation alone, according to the study.

Other organizations, such as the American Academy of Pediatrics have guidelines in place to help with the management of children's screen time. The organization suggests putting realistic rules or limits in place for how long your children are on their screens, knowing who they are talking to and what they are doing. The amount of recommended screen time depends on the age of the child. Besides, parents should also make sure to encourage physical activity and have bedroom rules such as creating "tech-free zones".

1.Who are the target readers of this passage?

A. Researchers.　　 B. Teachers.

C. Parents.　　 D. Children.

2.What is the main idea of this passage?

A. A study on children’s screen time is published.

B. US children fail to meet movement guidelines.

C. Organizations are concerned about children’s cognition.

D. Limitation on children's screen time is linked to better cognition.

3.According to the passage, which of the following might contributes least to cognition?

A. Screen time limit.　　 B. Sleep hours.

C. Physical activity time.　　 D. Sleep hours and screen time limit.

4.Why does the American organization suggest creating "tech-free zones”?

A. To make sure children have enough physical playtime.

B. To make sure children have enough sleep time.

C. To make sure children have recreational time.

D. To protect children against radiation.

After a year of preparing herself, Laura Dekker has been given permission to sail around the world. “I was so happy that I almost jumped into the river,” Laura said, after learning of the court’s verdict(判决).

The 14-year-old was born on a ship in the South Pacific, and currently lives with her father on a boat. When child protection agencies heard about her plan to sail alone, they took the case to court and prevented her from making such a dangerous voyage.

Since the decision, though, Laura had been preparing with her father to convince the court that she was ready. Later on, she received the books and other materials she would need for school while she was at sea. She added safety equipment to a new, big ship. And she took her first aid course to learn several survival skills, like how to put out fires on the boat, take care of her own injuries and deal with lack of sleep. She also planned a safer course --- adding alternate routes(备用路径) to avoid pirate attacks, and planning a course that would have her on dry land as she moved from port to port across the globe.

Even with all of the added preparations, the trip still has its risks. In early June, 16-year-old Abby Sunderland, an American, had to abandon(放弃) her attempt to become the youngest sailor to travel around the world. Her ship’s mast(桅杆) broke due to rough waters in the Indian Ocean, and she was rescued by a French fishing ship.

Laura plans to take longer than Abby for her voyage, and is using a larger and more stable boat. If she finished successfully in less than two years, she will take the title from current record-holder Jessica Watson, of Australia, who was 16 when she completed the journey.

1.Which of the following is TRUE of Laura?

A. She prepared the voyage at the age of 12.

B. She lost her mother after she was born.

C. She was allowed to sail around the world finally.

D. She wanted to donate money made from the voyage.

2.At first, child protection agencies were against Laura’s plan because ____.

A. it was considered to be a dangerous trip

B. Laura had to finish her schooling first

C. it would cost Laura too much time and money

D. Laura wasn’t prepared for the sailing alone

3.What is Mr. Dekker’s attitude towards Laura’s trip?

A. Doubtful     B. Supportive   C. Uncertain        D. Neutral(中立的)

4.Paragraph 3 mainly talks about ____.

A. how Laura convinced the court

B. why Laura needed to study at sea

C. how Laura prepared for the voyage

D. where Laura could avoid pirate attacks

5. The person who keeps the record comes from ____.

A. Holland  B. America  C. India        D. Australia
