Everyone should get enough sleep. If a student doesn't sleep well at night， he won't study well and he can’t listen to the teacher carefully in class. For a driver， it is easier for him to have an accident (事故) if he is tired. Good sleep is also important for your health. Without good sleep， a person may become ill.
It is hard for some people to sleep well. A lot of things can help you get a good night's sleep. First， doing some exercise will help you sleep. Walking， running and bike riding are good ways. Other good ways are playing ball games， such as basketball， soccer or tennis. However， you must not do these just before bedtime.
Second， before you go to bed， you shouldn't drink coffee or any soft drinks. It is also not a good idea to eat sweets. But drinking a cup of warm milk may help you to sleep.
Third， you can take a warm bath or listen to quiet music before you go to bed. Many people find that they are helpful to sleep.

Look at the first picture．This empty box must fall over, because its center of gravity (C) is not above the line of its bottom (AB)．

In most parts of the world，many students help their schools make less pollution．They join“environment clubs”．In an environment club，people work together to make our environment clean． Here are some things students often do．
●No-garbage (垃圾) lunches．How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again．Every week they will choose the classes that make the least garbage and report them to the whole school!
●No-car day．On a no—car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember：
Walk，jump，bike or run．
Use your legs! It’s lots of fun!
●Turn off the water! Did you know that some toilets can waste (浪费) twenty to forty tons of water an hour? In a year, that would fill a small river! In environment clubs，students mend those broken toilets．

The brain receives information from the outside world through the sensory (感觉的) system．This information is collected through the eyes，the nose，the ears，the mouth and the surface of the body．It is then kept in the memory．In fact，scientists do not completely understand how the memory works but they are not sure how much information that the human brain can store．Also， it appears that the information is never lost．Very old people often remember things that happened in their childhood which have not come to their minds for sixty to seventy years．If we have kept something in our memory, it is here．But can we get it out again and use it? That is the difficulty．
Some of the information we receive only goes into the Short Term Memory．We only keep this information for a minute or two，then we lose it．This temporary (暂时的) memory is very important in our thinking and understanding．It is used，for example，when you try to remember a name that someone told you a moment ago or a telephone number that you are going to dial (拨)．School children in class often seem to use the Short Term Memory if they are not interested in the subject．When school teachers describe this，they say that things go“in one ear and out in the other”．But if a child is interested，he puts the information in his Long Term Memory, and he never loses it．Long Term Memory depends heavily on our understanding of the meaning of the information we receive．Information is collected through theof sight，hearing，smell，taste and touch．
| A．sense | B．experience |
| C．practice | D．brightness |
Very old people can remember something happened．
| A．recently | B．about seventy years ago |
| C．in their thirties | D．in their classroom |
If a school child is not interested in a subject，．
| A．he forgets what he learns quickly |
| B．he memorizes what he learns quickly |
| C．he forgets what he learns slowly |
| D．he memorizes what he learns slowly |
The better we understand the meaning of the information，．
| A．the more information we can put in our Short Term Memory |
| B．the more information we can put in our Long Term Memory |
| C．the less information．we can put in our Short Term Memory |
| D．the less information we can put，in our Long Term Memory |
