The survey was among（在…之間） 1,000 British children from 12 to 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 39。junk sleep39。. It means you don39。t get enough sleep and the quality（質(zhì)量）of the sleep is bad, too. If you don39。t get good rest, you don39。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.

There are three different kinds of friends: pest friends, guest friends, and best friends. The first kind of friend is simply acquaintances （熟人）, and all you usually know about them is their names. You may meet this kind of friend at school, at work, or on the bus, but you don39。t miss them when they39。re not around. When this kind of friend does something bad, you don39。t tell them. That is why they are called pest friends. The second kind of friend could also be called social partners. They are closer than acquaintances, but not as close as true friends. You know their names, a little of what they like or dislike, and a little of their family histories。 you usually have a few things in mon, but you don39。t talk about anything deep（深）, such as your wishes or fears（害怕）, and they don39。t open up to you how they really feel. The last kind of friend, the best friend, is the one you know the deepest. You39。re like family, and know everything about each other. You have no problem staying at each other39。s houses, and you share your deepest feelings and thoughts. They will correct you when you39。re wrong, and though they may not be perfect（完美的）, they at least will always care about you, and never do anything on purpose（故意地）to hurt you. We all have our pest, guest, and best friends. We should value（ 重 視 ）all friendships and remember, all best friends start out as just acquaintances.（1）If you and David are neighbors and classmates, and do things together, but don39。t share their feelings, you are .
