You may know about “junk food” like hamburgers. But do you know about “junk sleep” ?

A British survey found that electronic products(电子产品) in teenagers' bedrooms are affecting(影响) their sleep.

The survey was among(在……之间) 1,000 British children between 12 and 16. It found that 30% of them got just 4 to 7 hours of sleep every day. But doctors say they need 8 to 9 hours.

Almost 25% 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(质量) of the sleep is bad, too. If you don't get a good rest, you won't perform well in school the next day.”

The survey found that 40% of the kids felt tired each day, with girls between 13 and 16 feeling the worst. Nearly all the teenagers have a phone, an MP4 or a TV in their bedrooms. And many of them have all three.

Around the world more and more people are taking part in dangerous sports activities.Of course,there have always been people who have looked for adventure— those who have climbed the highest mountains,explored unknown parts of the world or sailed in small boats across the greatest oceans.Now,however,there are people who seek(寻找)a risky activity,which may only last a few minutes or even seconds.

Bungee jumping is a good example of such an activity.You jump from a high place 200 metres above the ground with an elastic(有弹力的)rope tied to your feet.You fall at up to 150 kilometres an hour until the rope stops you from hitting the ground.It__is__reported__that__two__million__people__around__the__world__have__now__tried__bungee__jumping.

Why do people take part in such activities like this?Some psychologists(心理学家)suggest that it is because life in modern societies has become safe and boring.In ancient times,people had to face danger and difficulties.They had to go out and hunt for food.Diseases could not easily be cured,and there was a continuous battle for survival(生存).

Since last year, short videos have gotten tons of attention online. Many people create and share short videos on popular video apps like Douyin and Kuaishou. You can even add music and special effects (特效) to your videos. The videos are 15 seconds to a few minutes long. They show people doing activities like cooking, exercising and singing.

Teenagers especially enjoy these videos. Many junior high school students said they enjoyed watching these short videos. The videos let teenagers see funny and exciting things they don't usually see.
