　　Dear Dad,

　　I'm writing this letter to you because it's too difficult to talk about it．I can't stop thinking about my uncle and how he died．In fact, I seriously want to ask you to stop smoking．I've looked up a lot of information about smoking and I've found out some disturbing(令人不安的)things．

　　You already know that smoking is bad for your breathing and can cause cancer．I've found out that it causes many other illnesses as well．Did you know that over 100,000 people die from smoking every year in Britain?It's the second biggest cause of death in the world．I don't want you to be one of these people．

　　When Mum asks you to smoke outside, you think she's just being difficult．Well, it's true that she doesn't like the smell of smoke in the house and on our clothes．It's not very pleasant．However, when you smoke, it's also bad for me and Mum．In other words, when we breathe in your smoke, it's like we're smoking ourselves．As a result, we can get diseases as well．Doctors are finding that more and more non-smokers are falling ill because of the effects of other people's smoking．

　　I know that it is very difficult to stop smoking but you mustn't give in(屈服)to it．Please see the doctor and ask him for help．We will do anything we can to help you．You must try to save your own life．You are important to us and we don't want to lose you．Who else can I ask to help me with my maths homework or fix my bike?Please don't smoke!

　　Do you know why you sleep?You may think it's because you're tired．Or perhaps you've been told sleep is good for you．Yet no one knows exactly why or how people sleep．

　　Until the early 1950s, most scientists thought the body and the brain rested during sleep．Then a scientist watched people sleep．He noticed that during periods of between 5 and 30 minutes, sleepers' eyes made rapid movements, as if they were watching something．He called these periods REM(Rapid Eye Movement)sleep．He called periods when sleepers' eyes did not move non-REM sleep．

　　Whenever the scientist woke people during REM sleep, they were having vivid dreams．Measurements(测量)showed that sleepers' pulses(脉搏)went up quickly during REM sleep．Their breathing, heartbeat, and the blood going to the brain also increased．Far from being a time of rest, REM sleep is a time when the body is hard at work．Scientists still don't know the reason for this．Some believe REM sleep helps the brain grow．Others think REM sleep is a time for the brain to empty the day's garbage．

　　One thing all the scientists agree on is that sleep is necessary．Without enough sleep, people make mistakes．Most car accidents happen during the early morning hours when people are sleepiest．
