    Your Nose is Busy and Important
    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.

    Many people write to newspapers and magazines to express their opinions. Letters to the editor must carry the writer’s full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. Responsibility is the name of the game.
    “People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer’s signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.
    There are people who wish to remain anonymous(匿名的) for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he doesn’t want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.
    Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter of responsibility to use it when we make a statement, a claim or an accusation. We all want to honor our own name, and it is only by stamping our expression of an opinion with our name that we honor what we say.
    【小题1】What does the writer mean by saying “Responsibility is the name of the game”?
    A．Writers should be responsible for their names.
    B．Writers need to provide their personal information in the game.
    C．Names are required to indicate writers’ responsibility for what they say.
    D．Publications must bear the writer’s full name, address and phone number.
    【小题2】The second paragraph suggests that a paper without a signature may______.
    A．not get a reply B．be accepted all the time
    C．become a family problemD．help to end a relationship
    【小题3】Some people don’t want their names known because they are_______.
    A．ready for involvementB．hesitant to make a donation
    C．afraid of an accusation D．unwilling to draw public attention
    【小题4】The passage is mainly about_____.
    A．honor and writers B．signature and responsibility
    C．identity and signature D．anonymity and signature
