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 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.

Dear Dr Jackson, 
My parents are never happy with me. They are always criticizing (批评) my clothes, my hair and the music I listen to. They hate my friends' looks and they keep complaining when I go with them. I'm not allowed to stay out as late as my friends do, so I can't have any fun, My parents only seem to care about my school marks. Although I love them, sometimes I feel we live in different worlds. If they love me, can't they understand me? How can I make them understand me? 
Dear Angel,
Your problem is common (共同的) to both teenagers and parents. Don't worry, bacause all this is natural.You see, your parents have grown up at a different time and they have different experiences. So, they think some things are strange, but you find the same things ordinary. For example, the music you like may sound like noise to them. Your parents love you, so they feel they must protect you from whatever they find strange.On the other hand, you don't want to be different from other teenagers, so you feel that your parents restrict you. 
I think you should talk about this problem with your parents. Try to explain to them what you want and make them know they can believe you. Sooner or later. they'll find you are a responsible (有责任心的) person and they will give you more freedom (自由).
【小题1】Why has Angel written to Dr Jackson?

Napping(小睡) after learning something new could help improve your memory--- as long as you dream, scientists say.

   They found people who dream about a new task do it better on waking than those who do not sleep or do not dream.

Volunteers were asked to learn the layout(布局，设计) of a 3D computer maze(迷宫) so they could find their way several hours later. Those allowed to take a pap and who also remembered dreaming of the task, found their way to a landmark quicker.

   The researchers think the dreams are a sign that unconscious(无意识的) parts of the brain are working hard to process information about the task..

   Dr. Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels.

   Study tips

   Co-author Dr. Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem(认为) are the most important.

   “Every day we are gathering lots of information and new experiences,” she said. “It would seem that our dreams are asking the question, “How do I use this information to inform(影响) my life?”

   The scientists say there may be ways to use this phenomenon(现象) for improving learning and memory. For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study.

“Mind your own business．” we’re told．“Don’t talk about others behind their backs．”The problem with this advice is that，not only is it unrealistic，it’s also counterproductive(起反作用的)．

??? Common sense holds that gossip(流言蜚语)hurts people’s feelings and damages relationships．But recent research shows the opposite—that strong communities and relationships between people would be impossible without gossip．

??? Gossip is a way for people to let you know the limits of social behavior．“If you move into a community and your neighbor tells you how the former homeowner never dealt with his rubbish properly，his gossip is letting you in on something，”says Dr．Ralph Rosnow of Temple University．“Gossip says：these are the boundaries and you are crossing them．You’re not abiding by the rules and you’d better get back in line．” Seen this way，gossip is a way to communicate criticism(批评)without conflict(冲突)，giving you a chance to change your behavior without losing face．

??? On the other hand，what about ill-willed gossip，the kind that puts other people down? Gossip is hearing something we like about someone we don’t and，in nearly every country in the world，gossip magazines have huge numbers of readers．According to researchers，however，this kind of gossip also has a good side because it helps us put our own problems in perspective(正确地)．“If we read bad news about well-known people，or get the frightful details of our neighbors’ bad situation over a cup of coffee，our own problems begin to pale in comparison(对比)，”says Dr．Jack Levin of Northeastern University．

??? However，that doesn’t mean that gossip is necessarily a good thing，either．Researchers found that people who gossip a lot tend to feel like they’re under a lot of stress．This might be because while they’re busy talking about other people，they’re also busy thinking what other people are saying about them．
