Germs are everywhere. You can′t see them, but they are on your desk, on your computer, and even in the air!
Like people, germs move around the world. They fly with us on planes. When food, clothes, and other things travel around the world, germs travel, too. Some germs are safe, but some are dangerous. Germs cause illnesses like colds and the flu.
Warmer Weather Brings Germs
The world′s weather is changing. Cooler countries are getting warmer, so insects from hot countries can move there. Some of these insects, like mosquitoes, carry dangerous germs. These germs cause headaches, fever, and can even kill people.
Under Your Skin
Your skin protects you from germs. It stops some germs, but not all. They can enter your body when you eat, or when you have a cut. Germs are on your hands, too. They enter your body when you touch your eyes, nose, or mouth.
Your immune system (免疫系统) protects you, too. When germs get inside your body, your immune system finds and kills them. Special cells (细胞) move around your body and fight germs. They help you stay healthy. Other cells make antibodies. Antibodies help your body find and stop germs.
What can you do to fight germs? You should wash your hands with soap and water. Soap kills many germs, and water washes them away.
What do antibodies do?

There is no creature that does not need sleep or complete rest every day.
If you want to know why,just try going without sleep for a long period of time.You will discover that your mind and body would become too tired to work properly.You would become irritable and find it hard to think clearly or concentrate on your work.So sleep is quite simply the time when the ceils of?your body recover from the work of the day and build up supplies of energy for the next period of activity.
One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down.
For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do.
Your body temperature becomes lower when you are asleep,which is the reason people go to sleep under some kind of covers.And even though you are unconscious,many of your reflexes(反射动作)still work.For instance,if someone tickles(使觉得痒)your foot,you will put it away in your sleep,or even brush a fly from your forehead.You do these things without knowing it.

A.when you are asleep

Look After Your Voice

Often speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem
by activating the saliva in you mouth.First gently bite the edges of your tongue with your teeth.Or press
your entire tongue to the bottom of your mouth and hold it there until the saliva flow.Or you can imagine that
you are slicing a big juicy lemon and sucking the juice.
Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat.
Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.
If you sense that your are losing your voice,stop talking completely.Save your voice for your speech.
You may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you
need to see a doctor,perhaps you can get some advice from a professional singer. In the meantime,do not
even talk in a low voice.
What about drinking alcohol to wet your throat?I advice you not to touch alcohol before speaking. The
problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more
confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain
and your mouth do not work together properly.Save the alcohol until after you finish speaking.
Perhaps you want to accept the advice,but you may wonder if you can ever change the habits of a life-
time.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn
to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop
your new habits.If you are willing to change,you will soon be able to say that you will never forget these
techniques because they became a part of your body.

What did Goethe say about skating and swimming?
A:He said people could learn to skate when it was hot and swim when it was cold.
B:He said people could learn to skate and swim when it was hot.
C:He said people could learn to skate and swim when it was cold.
D:He said people could learn to skate when it was cold and swim when it was hot.
