Has anyone else ever heard your voice? Again you say, "Of course."
But that"s not quite true. Nobody else has ever heard your voice-the way you hear it. When you talk,
you set up sound waves (声波). The air outside your head carries the sound waves to your outer ears.
But, of course, the sound of your voice begins inside your head. The bones (骨头) of your head pick up
the sound waves, too. They carry the sound waves straight to your inner (里面的) ears. You get the sound
from the outside and the inside too. Other people get just the sound waves from the outside. That"s why
they don"t hear your voice the way you do.
B. air
C. waves
D. voice
B. outside your head
C. in your inner ears
D. in your outer ears
B. from the outside
C. from the inside
D. all of the above
A. to raise
B. to get
C. to choose
D. to pull
B. the way you hear your own voice
C. voice gets around far and wide
D. the different ways you and others hear your voice

核心考点
举一反三
there are pains all over your body. You don"t want to work, you stay in bed, feeling very sad.
What makes us ill? It is germs (细菌). Germs are everywhere. They are very small and you can"t find
them with your eyes, but you can see them with a microscope. They are very small and there could be
hundreds of them on a very small thing.
Germs are always found in dirty water. When we look at dirty water under the microscope, we shall
see them in it. So your father and mother will not let you drink dirty water.
Germs aren"t found only in water. They are found in air and dust. If you cut your finger, if some of the
dust from the floor goes into the cut (割开处), some of the germs would go into your finger. Your finger
would become big and red, and you will have much pain in it. Sometimes the germs would go into all of
your body, and you would have pain everywhere.
B. If things can"t be seen, they must be germs.
C. Germs are only in dirty water.
D. Germs are everywhere around us.
B. Making very big things look much smaller.
C. Helping you read some newspapers.
D. Helping you if you can"t see things clearly.

| There are four seasons in a year in China. Spring comes in February. May, June and July make the summer season. August, September and October make the autumn season. November, December and January make the winter season. In different seasons people wear different clothes and do different things.

| The common cold is the world"s most widespread illness. The most widespread mistake of all is that colds are caused by cold weather. They are not. They are caused by viruses (病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold weather causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers (探险者) have reported being free from colds until coming into contact again with the outside world by way of packages and mails dropped from airplanes. During the First World War soldiers who spent long periods in the trenches, cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the notorious Auschwitz concentration camp, naked and starving, were extremely surprised to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in the experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty rooms. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose. If, then, cold and wet have nothing to do with catching colds, why are they more frequent (often) in the winter? Despite the most painstak- ing research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on. No one has yet found a cure for colds. There are drugs and pain sup- pressors such as aspirin, but all they do is to relieve the symptoms (症状). 1. Are the common colds caused by cold? ________________________________________________________________. 2. When may Arctic explorers catch colds? ________________________________________________________________. 3. How many kinds of people does the writer mention when explaining his idea? ________________________________________________________________. 4. Why arc the colds more frequent in the winter? ________________________________________________________________. 5. What is the key point of this passage? ________________________________________________________________. |
