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!

    What do you read when you are travelling by train or bus? What are other people reading? Perhaps a woman sitting near you is reading a love story. A man is reading a serious biography(自传) about a president. And there's a student reading an English textbook.

    What do their choices(选择) say about them? Do you think you can know them by what they are reading? I have got to tell you that your feelings of them may be quite wrong. The woman reading the love story could be a lawyer. She just wants a light read to take her mind off work. The man reading the biography wants you to think that he is very clever. The student reading the textbook isn't a student at all. She's an English teacher.

    Publishers(出版商) know that some people care what they read on trains or buses and so they put out different types of covers. For example， books about Harry Potter have a cartoon cover for young readers and then another more serious cover for grown—ups.

    So next time you are on a train， look around and see what other people are reading， but don't jump to any conclusions(结论). You will be wrong maybe.

Here is a sentence that you could say， “Don't judge（判断） a book by its cover”.

    Life in the future will be very different from life today. What will the change(变化)be? There will be changes in our food. Maybe(或许)no one will eat meat every day. They will eat fruit and vegetables. Computers will be very small, and there will be at least(至少)one in every home. People will take the computers in their pockets. Work in the future will be different, too. Robots will do dangerous and hard work. People will have more free time to travel.

    Liu Wei is very famous in China because he can play the piano with his toes(脚趾). One day when Liu Wei was only 10 years old, he played a game with some friends. He lost both his arms because of electricity(电). Liu Wei was very sad when both his arms were cut off after the accident. But soon he had to make a choice. "For people like me, there were only two choices. One was to give up all the dreams, which would cause a quick death. The other was to work hard without arms to live an excellent life." says Liu Wei. Liu's dream was to be a pianist. His excellent life included a show on China's Got Talent(《中国达人秀》) and a wonderful performance(演奏) playing the beautiful Marriage D'amour with his two feet on the piano. Liu Wei learned to play the piano with his feet. And teaching himself to play the piano with his feet was very hard. Many times he wanted to give it up, but his parents went on encouraging(鼓励) him and he wanted to make his parents proud. Maybe you can not believe that Liu Wei is able to play well only with his toes. The audience(观众) were deeply moved and very excited when they watched his performance.
