You may know about “ junk food” like French fries. But do you know about “junk sleep”?
Recently, a British survey found that electronic(电子) products in teenagers bedrooms are affecting(影响)their sleep.
The survey was done among 1,000 British kids from 12 to 16. It found that thirty percent of them got just 4 to 7 hours sleep every day. But doctors say they need 8 to 9 hours.
Almost a quarter of the kids said they fell asleep more than once a week while watching TV, listening to music or using other electronic products.
“This is very worrying.” Said Dr Chris Idzikowski, a British expert, “We call it ‘junk sleep’, It means you don’t get enough sleep and the quality of the sleep is bad, too. If you don’t get good rest, you don’t perform well in school the next day.”
The survey found that 40 percent of the kids felt tired each day, with girls between 13 and 16 feeling the worst. Nearly all the teenagers have a phone, Mp4 or TV IN THEIR BEDROOM. And many of them have all three.

“The school” he said, “has a group of twenty-four boys between seven and thirteen.”
I should have to teach all the 【小题9】except art, which he taught himself.

Before I had time to ask about my salary(薪水), he got up to his feet. “Now,” he said. “You’d better meet my wife. She is the one who really runs this school.”

Beijing—No Car Day was first started by 34 cities in France on September 22, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.

The first No Car Day in China was in Chengdu in 2001. Other cities, including Beijing, Taipei, Shanghai and Wuhan also support the day.

In Beijing, more and more people are joining in the activity. It asks drivers to leave their cars for one day each week and walk, take a bus or subway or ride a bike to work. The slogan（口号）for the activity is,“If we drive for one less day, we can have one more nice day.” Beijing is trying to have 238 blue sky days this year. In the first quarter of this year Beijing only have 52 blue sky days. This was 11 days less than the number for the same period last year. Car exhaust(汽车尾气) is one of the most important reasons of the pollution. We must do more for No Car Day.
