【录音原文】
Some people are on restricted diets because they are allergic to milk or wheat products, for example, or for other health reasons. And lots of people try reducing diets in an effort to lose weight. You may know some kids or adults who complain about their weight and say that they should be on a diet.
Maybe you feel that you are at an unhealthy weight and should be on a diet, too. But how do you know? It’s difficult to determine what body shape and weight is just right for you because there is no perfect body shape. For example, some people just have broader body shapes or bigger bones than other people. These people will always look heavier than those with smaller bones.
It’s also normal for people to be harder on themselves than on others. Although others see your great smile and long legs, you may focus on the fact that your stomach isn’t as flat as you’d like it to be or that you think your rear end is wide. Try to focus on the good things about yourself.
Don’t look to TV or the movies to find the person you want to look like. These people are often on very strict and unhealthy diets to stay thin. And many models in magazines, newspapers, and on the Internet have been airbrushed to look perfect. These pictures and people are not realistic at all!
Instead, look around at people you see every day: what sorts of body shapes do your family members have? What do the athletes in your school or neighborhood look like? Looking at other healthy people you know may help you to feel better about your body. Are you still worried you might be at an unhealthy weight? Then it’s time to talk to your parent and maybe even see your doctor.

根据下面资料，回答Germs are everywhere. You can′t see them, but they are on your desk, on your computer, and even in the air! Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu. Warmer Weather Brings Germs The world′s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people. Under Your Skin Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth. Your immune system (免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells (细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs. What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away. Please fill in the blank with proper phrases to complete the title of the last paragraph. _______________________________________________________________________

共用题干Tiny InvadersThe human body is truly amazing. It allows us to sense the world around us,to do work and have fun, and to move from place to place.In fact,the human body does its work so well that most people don't think about it very much一until they get sick.The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there. They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.How can you stop these tiny invaders from making you sick?Your skin is the first defense against germs.You can prevent some illnesses simply by washing,with soap and water.

共用题干第三篇Look After Your VoiceOften speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in you mouth.First gently bite the edges of your tongue with your teeth.Or press your entire tongue to the bottom of your mouth and hold it there until the saliva flow.Or you can imagine that you are slicing a big juicy lemon and sucking the juice.Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat.Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that your are losing your voice,stop talking completely.Save your voice for your speech. You may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you need to see a doctor,perhaps you can get some advice from a professional singer. In the meantime,do not even talk in a low voice.What about drinking alcohol to wet your throat?I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain and your mouth do not work together properly.Save the alcohol until after you finish speaking.Perhaps you want to accept the advice,but you may wonder if you can ever change the habits of a life- time.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop your new habits.If you are willing to change,you will soon be able to say that you will never forget these techniques because they became a part of your body.What does the writer suggest when you feel you are losing your voice?A:Rest your voice.B:Drink some alcohol.C:Ask a singer to teach you how to protect your voice.D:Never go to see a doctor.
