We have known for a long time that flowers of different plants open and close at different time of day.
This is so familiar that there seems to be no need to ask the reason for it. Yet no one really understands why
flowers open and close like this at particular times. The process (过程) is not as simple as we might think, as
recent experiments have shown. In one study, flowers were kept in constant (连续的) darkness. We might
expect that the flowers, without any information about the time of day, did not open as they normally do. In
fact, they continued to open at their usual time. This suggests that they have some mysterious (神秘的) way
of knowing the time. Their sense of time does not depend on information from the outside world; it is, so to
speak, inside them, a kind of "inner clock".
         This discovery (发现) may not seem to be very important. However, it was later found that not just
plants but also animals -including man -have this "inner clock" which controls the working of their bodies and
influences (影响) their activities. Men, then, are also influenced by this mysterious power. Whether we wish
it or not, it affects such things in our life as our need for sleep, our need for food.
         In the past, this did not matter very much because people lived in natural condition. In the modern
world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who
have to work at night. It would be very useful, then, to know more about the "inner clock". Such ordinary
things as flowers might help us understand more about ourselves.

A. different flowers open and close at different times of day
B. for their opening and closing, flowers do not need information from the outside world
C. flowers are influenced by weak light even when they are in a dark room
D. flowers can be used for telling the time

2. The "inner clock" _______.

A. is an unimportant discovery
B. is only found in animals
C. has not been understood by far

A. it might help us in some way
B. we do not yet understand plants and animals well enough
C. the number of spacemen and airplane pilots is fast increasing
D. we should try to live more naturally than we do now

4. Kept in constant darkness, flowers _______.

A. will not open or close as usua
B. will not open any longer
C. will open as they do in natural conditions
D. will always remain in full blossom (开花)

5. ______ have a mysterious power of knowing time without information from the outside world.

         Many young people can use a computer, but few of them know how to look after it. Remember the
following tips when you use a computer.
         Keep your computer in a cool, dry room. Too much or too little heat is bad for computers. Damp (潮湿)
is also bad for them. Most computers work best at a temperature of 5-10 degrees centigrade (摄氏度).
         Do not let people smoke cigarettes near your computer. Smoke of all kinds is very bad for many parts of
the computer and can cause many problems.
         Do not eat or drink when you are near your computer. Pieces of food or drops of water on the keyboard
can also cause many problems.
         Make sure that the keyboard and the screen are the correct height for you. If they are not correct, you
will get backache.
         Make sure the screen is the correct distance from your eyes. If you wear glasses, make sure these glasses
are correct for using with the computer. Some people use a different pair of glasses when they use a computer.
         Keep your screen clean and do not have it too bright. A dirty screen can hurt your eyes. A very bright
screen can also be bad for your eyes. If you can afford one, buy a computer screen. It will be better for you
than using the screen of a TV set.
         Never use any software (软件) that you don't know whether they are clean or not. You must be careful
because some software can bring viruses (病毒) into the computer. If your computer has viruses, it can't work
or even breaks down.

(     ) 1. According to this passage, most young people can control computers well while paying little attention
            to the keeping of them.
(      ) 2. Putting the keyboard and the screen too high means you don't have to look at your manuscript (手稿)
             while typing.
(      ) 3. Some people use a different pair of glasses when they use a computer because they want to protect
             their eyes.
(      ) 4. It's better to use a TV set screen instead of a computer one because a TV set is usually larger than a
             computer one.
(      ) 5. "Clean software" means the software without any viruses.

        Mars is the fourth planet from the sun and is commonly known as the Red Planets. The rocks, soil and sky
of it are a little red or pink. Its name was given by the Romans in honor of their god of war.
        People on the earth need oxygen to breathe. There is almost no oxygen on Mars. Living on Mars would be
like living on a very high mountain. There would be little air. It might be 50 degrees above zero at noon and 100
degrees below zero at night. We know that Mars has carbon. Through a telescope, Mars looks red. In some
places, it seems gray. At times the gray turns gray-green, then brown, then gray again. The gray-green may be
a kind of plant color which changes with the seasons.
        Life is expected on Mars by scientists, because there are distinct seasons on the planet's surface. This
condition might support plants. However, some researches find if Mars had life, it must have been a long time
ago. For Mars' first 600 millions years, it had plenty of water and proper temperatures for life. But now the
planet's environment has changed. Mars is not a pleasant place for any form of life.
