译文
如果你看见有人晕倒，而你又了解一些急救措施，那很可能会挽救一条生命。
通常人们都是什么都不做，因为他们认为自己的做法可能会害死病人。但是学习些简单的措施你就可能救死扶伤了。
首先，你需要通过挤压他们脖子和肩膀之间的皮肤，并大声呼喊来确定他们是无意识了，还是睡着了或者喝醉了。
如果没有回应的话，你需要确定他们是死了还是仅仅是晕过去了，虽然有时很难分辨清楚。
把一只手放在他们的前额慢慢地把头向后倾，同时抬高下颚以确保呼吸顺畅。
如果没有明显的脉搏和心脏跳动，那就是没有生命迹象了。此时要立刻叫救护车并开始心脏救援以保持充了氧气的血液在大脑和心脏之间流通。
把你的手交叉相扣，按住胸腔中心部分上上下下不停地按，直到救护车到达。
保持一分钟一百次的频率。你这样做不会伤害到他们，但却能挽救一条生命。

08 Form Good Health Habits 养成好的健康习惯
Now you are going to read about some ways to care for your body.
Teeth are important to you. Have you ever hear someone talk who had no teeth？ They can’t speak clearly. You need teeth to help you talk right. A person who has no teeth has another problem， also. The face of that person is not as pretty as the face of someone with pretty teeth.
Another reason that teeth are important is that teeth chew your food for you. If you had no teeth， you would only be able to eat soft food. You could not eat steaks， apples， or hamburgers.
Tom’s father is a dentist， he came to the class to talk about caring for the teeth. He gave each student a toothbrush and a little tube of toothpaste. He had pictures that showed how to brush teeth the right way. He said. “Tooth care begins with eating the right kinds of food. Eat cheese， leafy green vegetables， and drink three or more glasses of milk a day. Try not to eat sweets. Fruits are better for you.
“You need to chew your food well. Chewing exercises the jaws， gums， and teeth. Exercise is healthful. Also， chewing starts digestion.
“Remember to brush or rinse your teeth with water after eating. Always brush your teeth the way they grow. Brush up on the lower teeth and brush down on the upper teeth. Brushing the right way helps get the tiny bits of food from between your teeth. Brushing the right way keeps you from brushing the food under the gums. If you brush across your teeth you may wear away the tooth.
“Be careful！ Do not use your teeth as a tool to bite into hard things or to crack nuts. You may chip or crack your teeth.
“You should visit your dentist twice a year， he can tell if any decay has started that you cannot see. Even when you brush your teeth carefully， sometimes little bits of food are left between the teeth. Use dental floss every day to get out these tiny bits of food that toothbrush misses.
Like your teeth， you need to take care of your sight. You must be careful to have enough light when you are reading. The light should come over your shoulder.
Don’t look right at the sun. When the sun is very bright， like at the seashore or in the snow， wear sunglasses. Good food helps your eyes， also. Carrots have vitamins in them that help you see at night. When you use scissors or pointed tools， be careful to keep the points away from your eyes. Be careful around other people， too. You do not want to hurt someone else’s eyes.
You have learned about how to care for your teeth and for your eyes. Now I am going to tell you about how to care for your body.
You should breathe deeply. Deep breathing helps your body to work its very best. Also， you should stand tall with your head high and your shoulders straight. When you stand right， the inside of your body has enough room to work its best.
You must eat the healthy foods. You need to drink water， also. If you drink four to six glasses of water each day， your body will work at its best， too.
You can use water for washing， too. You need to take a bath every day. You should wash your hair at least once a week. If you rinse your hair enough， your hair will shine. Wear clean clothes everyday， too.
Be sure that you have enough sleep at night. You should have eight to ten hours of sleep each night. You will be tired if you exercise your body each day. You need to keep it strong. Sleep will rest your tired body.
You keep your body clean. You should try to keep your thoughts clean， too. How you think makes you happy or unhappy. If you loved your friends， you will be kind to them. You should be kind and loving. If you fill your mind full of bad thoughts， you will not feel happy. To be healthy you don’t want to fill your body with junk food. In the same way， to have a happy， healthy mind， fill it with good thoughts about the world. You want to think the best， read the best， and act the best that you can.
