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!

    Some students, parents and teachers in Shanghai were surveyed last month. According to the result of the survey, the generation gap (代沟) between students and parents as well as teachers is becoming wider. Here is what they said.

    Voice of the students:

    "Our parents hold too high expectations（期待）which put us under lots of pressure（压力）. They care too much about our lives and studies," one student said.

    "It's impolite that some students' parents read their children's diaries without permission!" one student said angrily.

    "Some of our teachers are so serious that we can't make friends with them at all," another student said sadly.

    Voice of the parents:

    One mother said, "After school, my daughter usually locks herself into her room and spends lots of time talking with others on the phone. And I can't stand her clothes and hairstyle!"

    "I thought my son was doing very well in his studies. I didn't realize I was being cheated (欺骗) by him until I got a call from his teacher," said a father.

    Voice of the teachers:

    An English teacher said, "Today, the role of the teacher is to put knowledge into students' brain. The power teachers have kept students away from them."

    "Some parents pay too much attention to their children's grades. They never create a lively and colorful environment at home," another teacher said.

    "In the past, teachers and students often played games together or talked with each other. Today, only studies and grades are talked about," said a teacher.

    Voice of scientists:

    Scientists say that a school should be a place where students can learn not only knowledge, but also how to face failure bravely enough.

    One morning, a little mouse went out to find something to eat. He was careless and met a fierce (凶猛的) lion. The lion caught the mouse and wanted to eat him.

    "Please let me go, Mr. lion, "said the mouse." One day, I'll help you. "

    The lion laughed, "How could a little mouse help a big lion?" "Well," he said. "I will let you go. But you must walk more carefully. "

    The mouse was very grateful (感激的). "Thank you, Mr. Lion. You are very kind. I will repay (报答) you one day, " the little mouse said.

    The next week, the mouse was looking for something to eat again. He saw the lion under a tree. But the lion was tied tightly (紧紧地被捆着) in a net of strong ropes (绳子) .He could not get out.

    "I will help you, "said the mouse .His teeth were sharp. Then he bit (咬) one rope, and then another. Soon the lion was free. He was very pleased. "Thank you, Mr. Mouse,” he said.
