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?
( )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.
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.
B. rain
C. life
B. a stream
C. the mountains
B. mouth of a river
C. body of a stream
B. nature
C. oceans
B. Blood can be found in every living thing.
C. At the mouth of a river we can find many living things.
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.
B. why people have tears
C. why people cry when they are sad
D. what tears are

D. your eyes can"t open without them
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.
C. None of men can tell the difference between blue and green.
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 prisoners 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
