Your nose has many important jobs, and is always busy.

Smelling

    Smelling helps you gather information about the world around you. A good scent (气体),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.

Breathing

    Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (细菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.

Tasting

    Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (贡献) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn't taste as good because without smell, food loses most of its flavor.

Smell memory

    Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(气味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.

    Your nose has many important jobs, and is more than just a smeller!

    Rich or poor， young or old， we all have problems. We should learn how to deal with our problems. Here are some ways.

    Firstly， we should learn to forget.有时我们会生朋友的气。Good friendships may be lost. Sometimes children have disagreements and decide not to talk to each other. However， this usually does not last for long. This is an important lesson for us: we can solve a problem by learning to forget.

    Secondly， we should regard problems as challenges(挑战). Many students often complain about school.他们有太多的作业要做。They think the rules are too strict. Education is an important part of our development. As young people， it is our duty to try our best to deal with each challenge with the help of our teachers. Don't worry about our problems. Let's face the challenges.

    We got off the buses cheerfully. Laughing and shouting, we jumped and ran all over the place. It was the first time for us to be away from the parents. Some of us started to feel homesick However, when the night party find dances began, the homesickness(想家)was gone.

    The next day, everybody rushed to the boating class, hoping to be at the head of the others. At first, my friends and l worked hard, but the boat wouldn't listen to us and kept going round and round. Then the teacher taught us how to work together. After many tries, we did much better.

    Swimming class was my favourite. It was about the hottest time of a day and the best time to stay in the cool water. The swimming teacher was a funny man, and during the class he often made us laugh happily.

    During the week I learned a lot of new things and made many new friends. I also learned how to take care of myself.

    When you are learning English, you find it not clever to translate an English sentence, word for word, into your own language. Take the sentence "How do you do?" for example. If you look up each word in the dictionary, one at a time, what is your translation? It must be a wrong sentence in your own language. Languages don't just have different sounds, they are different in many ways. It's important to master(掌握) the rules for word order in the study of English, too. If the speakers put words in a wrong order, the listener can't understand the speaker's sentence easily. Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesn't change between the two pairs of sentences: "She only likes apples." "Only she likes apples." "I have seen the film already." "I have already seen the film."

    When you are learning English, you must do your best to get the spirit of the language and use it as the English speakers do.
