Do you get enough sleep?With so much homework it's often difficult to get the rest you need．But you need to try, because sleep keeps you healthy and it stops you getting fat．
Recently, a group of US scientists did a study(调查)of kids aged between 8 and 13．The study found that if kids sleep for just one extra(额外的)hour each day, the chance of their getting fat is cut by about 30 percent(30％)．
Why?When people don't get enough sleep, they become tired．When they are tired, they don't exercise enough．Also, kids like snacks：If they are awake(醒着的)an extra hour or two each day, they have more time to eat snacks or other unhealhy foods．
So, how much sleep should you get?Scientists suggest 10 to 11 hours a night for kids aged 5 to 12．For older kids, eight to nine hours will do．

阅读理解
You will have a lot of reading to do in this grade this year．You can do more of it in less time if you learn to read rapidly．
Perhaps you have been told about some habits (习惯) which keep a person from reading fast and have been strongly asked to break those habits which you might have．
Do you still have any of these bad habits?Check yourself by answering“yes”or“no”to these questions．
(1) Do you move your lips (嘴唇) when reading silently?
(2) Do you point to words with your finger as you read?
(3)Do you move your head from side to side as you read?
(4)Do you read one word at a time?
If you answer“yes”to any of these questions,start at once to break the habit．If you move your tips，hold your fingers over them，or hold a piece of paper be-tween your lips while you are reading．Then if your lips move，your will know it and can stop them．
If you point to words，hold the two sides of your book，one side with your left hand，the other side with your right hand．Then you won't have a free finger to use in pointing while reading．If you move your head，place your chin (下巴) in one hand and hold your head still (静止不动的)．
If you read no more than one or two or three words at a time，you need to work very hard in learning to take in (吸收) more words at each glance (一瞥) as your eyes travel across the lines of words．
Even if you do rather fast now，you can learn to read even faster．As you probably have been told，the secret of fast reading is to take in whole groups of words as each glance．Read in through groups and force (迫使) your eyes along the lines of words as fast as you can to make them go．Anyone who practices doing these things will he able to read faster．
