    The human body is truly amazing.It allows us to sense the world around us,to do work and have fun,and to move from place to place.In fact,the human body does its work so well that most people don't think about it very much一until they get sick.
    The germs（致病菌）that make people sick are everywhere.You can't see them, but they're there.They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you are breathing.There are two types of germs:viruses and bacteria（细菌）.Viruses are germs that can only live inside animals or plants.Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so good.They can make you sick.Bacteria can cause sore throats（喉痛）and ear infections.
    How can you stop these tiny invaders from making you sick?Your skin is the first de-fense against germs.You can prevent some illnesses simply by washing,with soap and wa-ter.But germs can still enter the body through small cuts in the skin or through the mouth, eyes,and nose.
    Once germs are inside your body, your immune（免疫的）system tries to protect you.It looks for and destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.That way you will not get the same illness twice.
    You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune system strong.You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are medicines.They contain germs that have been killed or weakened.
    The dead germs can't make you sick.Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your antibodies attack it.

    After they kill germs,antibodies stay in the body.
    A:Right
    B:Wrong
    C:Not mentioned

    答案：A
    解析：
    阅读下面这篇短文，短文后列出了七个句子，请根据短文的内容对每个句子作出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。
    【解析】
    题干意为“病毒只存活于动物或者植物的体内。”关键词为inside，在……之内；people or animals，动物或植物。根据关键词到文中找相关句为第二段第七句“Viruses are germs that can only live inside animals or plants.”，由此表明病毒是只能存活于动物或植物体内的致病菌。因此题干错误，故选B项。
    题干意为“所有的细菌都会导致生病。”从常识上来讲，一般比较绝对的说法都是错误的。第二段倒数第五句“Some bacteria are good.”明确说明，一些细菌是好的。所以选B。
    题干意为“清洗皮肤可以避免一些疾病。”以wash为关键词到文中去寻找关键句。由第三段第二、三句“Your skin is the first defense against germs.You can prevent some illnesses simply by washing, with soap and water.”可知可以简单地通过用水和香皂清洗来预防一些疾病。可见题干表述是正确的。故选A。
    题干意为“细菌可以通过眼睛进入体内。”我们以eyes作为关键字回文中找相关表述。第三段最后一句为“But germs can still enter the body through small cuts in the skin or through the mouth, eyes, and nose.”由此可知，细菌可以通过口眼鼻等途径进入体内。所以题干表述正确，选A。
    题干意为“心脏有体内最强健的肌肉。”全文根本没有提及过muscle (肌肉）的话题。所以本题选C。
    题干意为“杀死细菌后，抗体留在体内。”此题可以以kill, antibodies和stay 这三个关键字中的任一个到文中查找到相关句为第四段倒数第三句：“After a germ is de-stroyed, the antibodies stay in your body.”由此可见题干表述正确，所以本题选A。
    题干意为“疫苗会让你生病。”最后一段讲的是Vaccines (疫苗）的相关话题。由本段第三、四、五句“Vaccines are medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.”可知疫苗是死的或者弱化的细菌，不会致病。所以题干的表述是错的。故本题选B。

    Passage Two

    One day I was at the airport waiting for a ticket to New York and the girl in the ticket office said, "I'm sorry, I can't sell you a ticket. Our computer is down."

    "If your computer is down, just write me out a ticket."

    "I can't write you out a ticket. The computer is the only one allowed to do so."

    I looked down on the computer and every passenger was just standing there staring at the black screen. Then I asked her, "What do all you people do?'

    "We give the computer the information about your trip, and then it tells us whether you can fly with us or not."

    "So when it goes down, you go down with it."

    "That's good, sir. '

    "How long will the computer be down?" I wanted to know.

    "I have no idea. There's no way we can find out without asking the computer."

    After the girl told me they had no backup (备用) computer, I said. "Let's forget the computer. What about your planes? They're still flying, aren't they?"

    "I wouldn't know," she said, pointing at the dark screen. "Only 'IT'knows. 'It'can't tell me.

    By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people started to cry and still others kicked their luggage.

    36. The best title for the article is______.

    A. When the Computer Is Down

    B. How to buy a ticket

    C. The Computer of the Airport

    D. Asking the Computer


    正确答案：A

    36．答案为A  根据文章第1段中的our computer is down及后面的文章内容，作者在机场遭遇电脑系统死机，可推知此题答案为A。

    The human body is truly amazing. It allows us to sense the world around us,to do work and have fun,
    and to move from place to place.In fact,the human body does its work so well that most people don't think
    about it very much-until they get sick.
    The germs（致病菌）that make people sick are everywhere. You can ' t see them , but they ' re there.
    They're sitting on your desk.They're hiding on your computer's keyboard.They're even in the air that you
    are breathing. There are two types of germs : viruses and bacteria（细菌）.Viruses are germs that can only
    live inside animals or plants. Viruses cause illnesses such as flu and measles（麻疹）.Bacteria are tiny
    creatures.Some bacteria are good.They can help your stomach break down food.Other bacteria aren't so
    good. They can make you sick. Bacteria can cause sore throats（喉痛）and ear infections.
    How can you stop these tiny invaders from making you sick?Your skin is the first defense against
    germs.You can prevent some illnesses simply by washing,with soap and water. But germs can still enter the
    body through small cuts in the skin or through the mouth,eyes,and nose.
    Once germs are inside your body , your immune（免疫的）system tries to protect you. It looks for and
    destroys germs.How does it do that?Special cells patrol your body.Some of these cells actually eat germs!
    Other cells make antibodies.An antibody sticks to a germ.There is a different antibody for each kind of
    germ.Some antibodies keep germs from making you sick.Others help your body find and kill germs.After a
    germ is destroyed,the antibodies stay in your body.They protect you if the same kind of germ comes back.
    That way you will not get the same illness twice.
    You can keep your body healthy by eating a nutritious（有营养的）diet to make your immune systerm
    strong. You can also help your immune system fight germs by getting vaccinated（接种）.Vaccines are
    medicines.They contain germs that have been killed or weakened.The dead germs can't make you sick.
    Instead,they cause your body to make antibodies.If the same germ ever shows up again,then your
    antibodies attack it.

    The heart contains the body's strongest muscle.
    A:Right
    B:Wrong
    C:Not mentioned

    答案：C
    解析：
    由文章第二段的第七句“Viruses are germs that can only live inside animals or plants.”可知，病毒只能生存在动植物体内，故选B。
    由第二段内容可知，致病菌有两种：一种是细菌；一种是病毒。病毒会致病，但有一部分细菌是良性的，故选B。
    由文章第三段第三句“You can prevent some illnesses simply by washing, with soap andwater.”可知，通过用水打上肥皂清洗皮肤可以预防一些疾病，故选A。
    由文章第三段最后一句中“germs can still enter the body through...eyes and nose”可知，致病菌可以通过伤口、口、眼、鼻等进入人体，故选A。
    文章并未提及心脏含有人体最强健的肌肉，故选C。
    由文章第四段倒数第三句“After a germ is destroyed, the antibodies stay in your body.”可 知，在毁掉致病菌以后，抗体会留在人体中，故选A。
    由文章最后一段内容可知，疫苗是接种到人体中用以抵抗致病菌的；疫苗是一种药物， 故选B。第3部分：概括大意与完成句子
