完型填空。     The earth is our home. We must take care of it. Life today is easier that it was   1   years ago, but it
has brought some new problems. One of the biggest problems is pollution. We can see it, drink it and
even hear it.
     Man has polluted the   2  . The more people, the more pollution. Many years ago, the problem was not
so serious because there were not so   3   people. When the land was used up (用光) or the river was not
clean in a place, man went to   4   place. Now man is slowly polluting the whole world. 
       5   pollution is still the most serious, it"s bad for   6   thing in the world.
     Many countries don"t let people burn (燃烧)   7   for air in houses and factories in the city. Pollution by
SO₂ is now the most dangerous kind of air pollution. It"s   8   to ride bikes. When you are tiding, there is no
pollution. But even in developed countries, most people don"t go to work by bike. It"s not because bikes are
expensive or people are tired if they ride to work. It"s because the number of cars on the roads becomes
larger. So more people   9   their bikes and go to work by car, then things are getting worse and worse. We
should have special roads only for bikes and make it  10  difficult and expensive for drivers to take their cars
into the city that they will go back to using their bikes.

Do you remember your dreams? Do people have the same dreams? Why do we dream? There are many questions about dreams. We dream during the REM (rapid eye movement) stage of sleep. We have about five periods of REM sleep during the night. The first REM cycle (周期) lasts about 10 minutes. As the night goes on, the REM cycle gets longer. By early morning, the REM cycle can last up to 90 minutes. Usually, it is in this last REM cycle that we remember our dreams.      Dreams change as people age. People may have several dreams each night. Some are like films and usually in colour. They come to us over and over again. That may be because the dreamer is worrying about something and trying to find the answer. Sometimes we wake up with a good feeling from a dream. But often we can"t remember the dreams clearly.      It is reported that too much dreaming is bad for our health. The more we sleep, the longer we dream. The mind is hard at work. That is why we may have a long sleep and still feel tired when we wake up?
(     )1. We dream during the REM stage of sleep.                                 (     )2. Children aged eight or nine have the same dreams as people aged thirty. (     )3. All the dreams are usually in colour like films.                       (     )4. The longer we dream, the better we sleep.                               (     )5. The passage above is talking about dreams.

Water is the "life blood" of our earth. It is in every living thing. It is in the air. It runs through mountains and valleys. It forms lakes and oceans. Water is everywhere.      Nature has a great water system (水系). Rainwater finds its way to streams (溪流) and rivers. Rivers lead to the oceans. At the mouths of the rivers, fresh water (淡水) joins the salt water of the oceans.      Here at the mouth of a river there is much important plant and animal life. Pollution destroys (毁坏) this life, so we have to clean our streams and rivers. Man has to work with nature-not against it.

When you feel sad, tears will come down from your eyes. When you are happy, especially when you laugh hard, tears will also come down from your eyes. But tears have a more important job than showing your feelings.      Tears keep your eyes clean and healthy. They wash away dirt and germs (细菌) just like bath. Your eyes also need tears to keep them wet. And eyes must be wet so that they can move smoothly. Your eyes are busy looking here and there all day long. They move quickly from one thing to another. If you didn"t have tears, your eyes couldn"t move, and soon you would be blind. Maybe you don"t like tears, but your eyes can"t do without them.

[     ]
A. what makes people blind B. why people have tears C. why people cry when they are sad D. what tears are

About ten men in every hundred have the trouble of color blindness in some way. Women are luckier, 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.
1. "Color blindness" means "______" in Chinese.
A. 盲目     B. 无色     C. 色盲     D. 讨厌颜色
2. Some people say it"s safer to be driven by women because ______.
A. women drive more carefully B. women are better at driving than men C. women can see things more clearly D. there are fewer color-blind women
3. With the help of the "cones", we can ______.
A. tell different shapes   B. kill insects C. see in the dark     D. tell orange from yellow
4. We can attract and kill mosquitoes by using a ______ light.
A. red     B. yellow     C. blue     D. green
5. Which of the following sentences about color blindness is TRUE?
A. None of men can see deep red. B. Not all of men have the same problem in recognizing colors. C. None of men can tell the difference between blue and green. D. All of men see everything in shades of green.
