only about one in two hundred is affected (感染) in this matter. Perhaps, after all, it is safer to be driven
by a woman.
There are different kinds of color blindness. For example, a man cannot see deep red. He may think
that red, orange and yellow are all shades (影子)of green. Sometimes a person can"t tell the difference
between blue and green. Only a few unlucky men may see everything in shades of green-a strange world
indeed.
Color blindness in human beings is a difficult thing to explain. In only one eye there are millions of very
small things called "cones (锥状细胞)". These help us to see in the bright light and to tell differences
between colors. There are also millions of "rods ( 杆状细胞)", but these are used for seeing when it is
nearly dark. They show us shapes but not colors.
Some insects have favorite colors. Mosquitoes (蚊子) like blue but do not like yellow. A red light
will not attract insects, but a blue light will. Human beings also have favorite colors. Yet we are lucky.
With the help of the cones in our eyes, we can see many beautiful colors by day, and with the help of
the rods we can see shapes at night.

B. Not all of men have the same problem in recognizing colors.

D. All of men see everything in shades of green.
most of us like eating sweets and ice cream better than meat and rice. Sweets and ice cream are not bad
for us if we eat them at the end of a meal. If we eat them before a meal, they may take away our appetite(食欲). So the doctors suggest us we should have our meal regularly.
In old England, the judges usually asked the pris
oners to eat bread without water. If they couldn"t swallow(吞)the bread, it meant that they weren"t telling the truth. Though this seems strange and foolish,
they thought it was an excellent way of finding out the truth. A man who is worrying about something has
difficulties in swallowing dry bread, because he loses his appetite.
B. happier
C. more beautiful
B. before a meal
C. when we are hungry
B. at the same time
C. at any time
B. eat a lot of dry bread
C. hardly (几乎不) eat dry bread
B. shy
C. unhappy
This is an old English saying. Have you heard of it before? It means that we must go to bed early
and get up early in the morning. Then we shall be healthy. We shall also be rich (wealthy) and clever
(wise).
This is true. The body must have enough sleep to be healthy. Children of young age should have
ten hours" sleep every night. Children who do not have enough sleep cannot do their work very well.
They will not be wise and they may not become wealthy!
The body also needs exercise. Walking, running, jumping, swimming and playing games are all
exercise.
Exercise keeps the body strong. Exercise also helps the blood (血液) to move around inside the
body. This is very important. Our blood takes food to all parts of our body. The head also needs blood.
Exercise helps us to think better!
B. be healthy
C. think better
D. have strong blood
B. won"t do well in his work
C. goes to school in time
D. has enough sleep
B. he has a lot of homework to do
C. he is strong enough
D. he does exercise
B. blood
C. children
D. head
B. A student should have 10 hours" sleep.
C. It"s good for you to get up early and go to bed early.
D. If you have enough blood, you"ll be wise.

| The World"s Water Shortage The world is not only hungry, but it is also thirsty for water. This may seem strange to you, since nearly 70 percent (百分比) of the earth"s surface is covered with water. But about 97 percent of this huge amount is sea water, or salt water. Man can only drink and use the other 3 percent the fresh water from rivers, lakes, underground, and other sources (资源). And we cannot even use all of that, because some of it is in the form of ice-bergs and glaciers (冰川). Even worse, some of it has been polluted. However, as things stand today, this small amount of fresh water is still enough for us. But our need for water is increasing (增加) rapidly almost day by day. Only if we take steps to deal .with this problem now can we avoid (避免) a severe (严重的) worldwide water shortage later on. We all have to learn how to stop wasting our valuable water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or runs into underground storage tanks. But it is possible to pipe used water to a purifying (净化) plant. There it can be treated with chemicals so that it can be used again, just as if it were fresh from a spring. But even if every large city purified and reused its water, we still would not have enough. All we"d have to do to make use of the vast reserves (贮备) of sea water in the world is to remove the salt. If we take these steps we"ll be in no danger of drying up. | |||
