Sometime early in the next century,human beings will move to Mars.They will live there for
about a year,and then will be replaced with another group of pioneers.Building the base on
Mars will advance our knowledge of the solar system and aid in our understanding of the earth.
We already know that Mars resembles the earth in many aspects:general size,presence of
water,length of day,range of temperatures.These resemblances have caused many ?people? to
consider a centuries?long project:to terraform Mars.Terraforming means altering a planet"s
surface so that Earth"s life forms can survive there.This concept,previously found only in science
fiction is now being seriously considered by scientists.
Terraforming Mars is theoretically simple:add nitrogen and oxygen to the atmosphere;pump
water to the surface;and add the earth"s plants and animals in the order in which they developed
on Earth.But it will take at least 300 years.
Some people think that such a project is too huge for ?humans? to undertake,but there are
very good reasons to make the attempt.The earth now contains some 6 billion ?people?,and
no one has any idea of how many humans the earth can support.Our very existence and numbers
are threatening many other species.We also have had some experience with terraforming our
own planet:altering the landscape,the atmosphere and the climate.Currently terraforming earth
has become a wiser activity as we try to control global warming,air and water pollution,and
preserve some natural living places.
While the possibility of such a project is small,it is not impossible.Even if earth bound societies
come and go in the next 300 years,the project can continue through the work of the Mars settlers
without the need for constant backing from the earth.
The future existence of all the people in our world may very well depend upon our ability to
terraform Mars.

Maybe you are an average student. You probably think you will never be a top student.
This is not necessary so, however. Anyone can become a better student if he or she wants to.
Here"s how:
1. Plan your time carefully. When you plan your week, you should make a list of things
that you have to do. After making this list, you should make a schedule of your time. First your
time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don"t forget
to set aside enough time for entertainment. A weekly schedule may not solve all your problems,
but it will force you to realize wha is happening to your time.
2. Find a good place to study. Look around the house for a good study area. Keep this
space, which may be a desk or simply a corner of your room, free of everything but study materials.
No games, radios, or television! When you sit down to study, concentrate on the subject.
3. Make good use of your time in class. Take advantage of class time to listen to everything
the teachers say. Really listening in class means less work later. Taking notes will help you remember
what the teacher says.
4. Study regularly. When you get home from school, go over your notes. Review the important
points that your teacher mentioned in class. If you know what your teacher is going to discuss the
next day, reading that material will become more meaningful, and you will remember it longer.
5. Develop a good attitude about tests. The purpose of a test is to show what you have
learned about a subject. They help you remember your new knowledge. The world won"t end if
you don"t pass a test, so don"t be overly worried.
There are other methods that might help you with your studying. You will probably discover
many others after you have tried these.
How to become a better student
really, and how do they operate?
Leadership today is not about forcing others to do things. If this is even possible, it is
short-term, and tends to backfire. If you order someone to do something against their will,
they may do it because they feel they must, but the anger they feel do more harm in the long-term.
They will also experience fear.
Fear causes the thinking brain to shut down, making the person unable to function at his or
her best. If they associate you with his emotion of fear, they will become less functional around
you, and you will have succeeded in not only shooting yourself in the foot, but possibly making
a very good employee or partner unable to perform effectively. Fear has no place in leadership.
The way we influence people in a lasting way is by our own character, and our understanding
and use of emotion. We can order someone to do something, which may be part of the work day;
or we can employ them at the emotional level, so they become fully devoted to the projects and
provide some of their own motivation. Today"s work place is all about relationships.
Anyone works harder in a positive environment in which they are recognized and valued as a
human being as well as a worker. Everyone produces just a bit more for someone they like.
Leaders understand the way things work. They know the pay check is not the single most
motivating factor in the work life of most people.
The true strength of leadership is an inner strength that comes from the confidence of emotiona
l intelligence-knowing your own emotions, and how to handle them, and those of others. Developing
your emotional intelligence is the single best thing you can do if you want to develop your relationships
with people around you, which is the key to the leadership skills.

C. give his employees a pay rise
D. hide his own emotion of fear
B. help raise employees" living conditions
C. give employees special instructions
D. deal wisely with employees" emotions

C. how to be a good leader
D. how to influence people
psychology think that there are also two groups of people: people who prefer warm colors and people
who prefer cool colors.
The warm colors are red, orange and yellow. Where there are warm colors and a lot of light, people
usually want to be active. People think that red, for example, is exciting. Sociable people, those who like
to be with others, like red. The cool colors are green, blue and violet. These colors, unlike warm colors,
are relaxing. Where there are cool colors, people are usually quiet. People who like to spend time alone
often prefer blue.
Red may be exciting, but one researcher says that time seems to pass more slowly in a room with
warm colors than in a room with cool colors. He suggests that a warm color, such as red or orange is a
good color for a living room or restaurant. People who are talking or eating do not want time to pass
quickly. Cool colors are better for offices or factories if the people who are working there want time to
pass quickly.
Researchers do not know why people think some colors are warm and other colors are cool.
However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet
are cool. Perhaps warm colors remind people of warm days and the cool colors remind them of cool
days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.
B. Blue, violet.
C. Black, blue.
D. Brown, white.
B. Warm colors can make people excited.
C. People who like to be with others don"t like red.
D. Where there are warm colors, people want to be active.
B. Orange for dining-rooms.
C. Blue for bedrooms.
D. Red for studies.
B. Warm colors remind people of warm days.
C. Cool colors remind people of cool days.
D. People have an agreeable opinion of warm colors and cool colors.
place to another at a certain time. They move for different reasons: most of them move to find food more
easily, but others move to get away from places that are too crowded.
When cold weather comes, many birds move to warmer places to find food. Some fishes give birth
in warm water and move to cold water to feed. The most famous migration(迁移) is probably the
migration of the fish, which is called "salmon". This fish is born in fresh water but it travels many miles to
salt water. There it spends its life. When it is old, it returns to its birthplace in fresh water. Then it gives
birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain homes when
they become too crowded. They move down to the low land. Sometimes they move all the way to the
seaside, and many of them are killed when they fall into the sea.
Recently, scientists have studied the migration of a kind of lobster(龙虾). Every year, when the
season of bad weather arrives, the lobster get into a long line and start to walk across the floor of the
ocean. Nobody knows why they do this, and nobody knows where they go.
So, sometimes we know why humans and animals move from one place to another, but at other
times we don"t. Maybe living things just like travel.

move when they dance. They keep on moving until the music stops.
People have enjoyed dancing for a very long time.This story is of a different kind of dance. It is a
dance without people or music. Yet this dance is one of the oldest in the world. It is the dance of bees.
If you have ever watched bees, you know that they are very clever. They also work hard looking for
food and bringing it back to their home.
The home of the bees is called a beehive. Here hundreds even thousands of bees live. They work day
and night building small walls of wax. There they make their honey. This is the same honey that we eat.
Where does the honey come from? Bees live on food from flowers. Have you seen bees flying around a flower garden? When a bee rests on a flower, it tries to go to the centre of it. There it takes in as much
food as its body can hold. Then it flies to take the food back to the hive.
At the hive, bees change this flower food into honey. Then they fly away for more food.
How do the bees know where to find the best food in the sweetest flowers? One bee acts as a guide.When it discovers good flowers, it flies back to the hive and tells the others. It does this by dancing for
them. The bee dances on one side. This tells the otherbees which way to go to find the flowers. But that is
not all. The bee dances for some time. And the length of its dance tells the other bees how far they must
fly to reach the flowers. When the bees see the dance, they know where the flowers are.
They fly away and return with more food for the hive.
Sometimes we hear the music of the bees as they fly around, but few people have ever seen them
dance. Yet without that dance we might never have sweet honey to eat.

C. bees dance more often than people
