Tiny Invaders
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.

All bacteria cause illnesses.
A:Right
B:Wrong
C:Not mentioned

答案：B
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。
