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!

    When I was about 6 years old, I lived in Kenya. On the roads, there were always street children asking for money. There was such a big difference between those children and me. At least I didn't have to worry about my living.

    My family had a wonderful driver, John, who had been working for us for years. He took me to and from school. One day, when we stopped in busy traffic (交通), a young street child went to us and called, "Hi, John!"

    John then gave him a little money and said goodbye to him with a smile before we went on to school. I was quite surprised. I knew that John worked hard to make money. He had a large family himself. We always sent food and clothes to his family. I couldn't understand why he gave money to the child.

    "Who was that?" I asked.

    "My friend," he replied. "Sometimes I see him on my way to work and I give him a little money."

    I was still unable to understand, so I asked, "Why do you give him money?"

    John replied, "So he can use it to buy some food."

    At that moment (瞬间q) I understood what kindness really was.

    Every Friday my grandfather gave me chocolates. I would save (保留) some so I could give them to John' s friend on the weekend.

    Do you remember the name of your kindergarten teacher? I do. Her name was Mrs. White.

    I don't remember much about what we learned in her class, but my mother once told me that we used to write a lot. And I would bring back what I wrote and she would look at it and see there were so many mistakes. But there were no red corrections but always a star. Sometimes even a word "Good"! That would make my heart filled with happiness, but it worried my mother.

    So one day when she went to meet Mrs. White, Mother asked her why she never corrected my mistakes, and why she never pointed out those mistakes. Mrs. White said, "The children are just beginning to get excited about using words, about making sentences. I don't want to make them lose that enthusiasm (热情) with red ink. Spelling and grammar can wait. The wonder of words won't ..."

    And thanks to Mrs. White, I had no qualms (顾忌) about writing what I meant even if I couldn't quite spell it out. Life isn't Perfect. It's Beautiful. She helped me understand it.
