discovered that some of his wheat was lying flat on the ground. The flattened wheat formed a circle about
six meters across. Around this circle were four smaller circles of flattened wheat. The five circles were in a formation like five dots (点) . During the following years , farmers in England found the strange circles in
their fields more and more often.
The circles are called "crop circles" because they appear in the fields of grain-usually wheat or com.
The grain in the circles lies flat on the ground but is never broken;it continues to grow, and farmers can
later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at
night. They appear only in the months from May to September.
At first, people thought that the circles were a hoax.Probably young people were making them as a
Joke or farmers were making them to attract tourists. To prove that the circles were a hoax , people tried
to make circles exactly like the ones that farmers had found. They couldn" t do it. They couldn " t enter a
field of grain without leaving tracks, and they couldn " t flatten the grain without breaking it.
Many people believe that beings from outer space are making the circles to communicate(交流) with us and that the crop circles are messages from them.
Scientists who have studied the crop circles suggested several possibilities. Some scientists say that a
downward rush of wind leads to the formation of the circles-the same downward rush of air that
sometimes causes an airplane to crash. Other scientists say that forces within the earth cause the circles to appear. There is one problem with all these scientific explanations; crop circles often appear in groups ,
like the five-dot formation. It is hard to believe that any natural force could form those.
B. his grain was growing up in circles
C. his grain was moved into several circles
D. some of his wheat had fallen onto the ground
B. a special way to plant crops
C. a research on the force of winds
D. an experiment for the protection of crops
B. The farmers couldn"t make the circles round.
C. The farmers couldn"t leave without footprints.
D. The farmers couldn"t keep the wheat straight up.
B. airplane crashes
C. new farming techniques
D. unknown flying objects

address,destination, purpose, and excuse. If I went to a friend"s house and found him not at home, his
mother might say,"Oh.he"s out in the woods." with a tone (语气) of airy acceptance. It"s similar to the
tone people sometimes use nowadays to tell me that someone I"m looking for is on the golf course or at the gym,or even "away from his desk".For us ten-year-olds, " being out in the woods" was just an excuse to
do whatever we feel like for a while.
We sometimes told ourselves that what we were doing in the woods was exploring (探索). Exploring was a more popular idea back then than it is today. History seemed to be mostly about explorers. Our
explorations, though, seemed to have less system than the historic kind: something usually came up along
the way. Say we stayed in the woods ,throwing rocks, shooting frogs , picking blackberries , digging
in what we were briefly persuaded was an Indian burial mound.
Often we got "Lost" and had to climb a tree to find out where we were. If you read a story in which
someone does that successfully, be skeptical; the topmost branches are usually too skinny to hold weight,
and we could never climb high enough to see anything except other trees. There were four or five trees that we visited regularly-tall beeches, easy to climb and comfortable to sit in.
It was in a tree, too, that our days of fooling around in the woods came to an end. By then some of us
has reached seventh grade and had begun the rough ride of adolescence (青春期). In March.the month
when we usually took to the woods again after winter, two friends and I set out to go exploring. We
climbed a tree,and all of a sudden it occurred to all three of us at the same time that we really were rather
big to be up in a tree. Soon there would be the spring dances on Friday evenings in the high school
cafeteria.
B. play golf and other sports
C. avoid doing their schoolwork
D. keep away from their parents
B. Human history is not the result of exploration.
C. Exploration should be a systematic activity.
D. The author explored in the woods aimlessly
B. doubtful
C.serious
D. optimistic
B. Lonely but memorable.
C. Boring and meaningless.
D. Long and unforgettable.
Suddenly a huge shark appears off shore and heads for the bathers. Before it can get close to the
swimmers, the shark, for some mysterious reason, starts swimming parallel to the beach. Then it turns
away from the shore and heads out to sea,leaving the swimmers untouched.
Such a scene will soon become common along shark-in-fested (鲨鱼成群的) shores. An electrical
engineer from the University of Pretoria has developed an electrical system that repels (击退 )
sharks by controlling their movements. Confused by this action, the sharks end up turning away from the
beach.
In this unusual shark-repellent method , an insulated (绝缘的)cable is buried on the bottom of the
sea around a beach where people swim. When an electric current is sent through the cable, an electric
field is produced in the water above the cable.
When a shark swims into the electric field, nerve cells just below the shark"s skin will detect the field.
The electricity produces a reflex(反射) action in the shark"s muscles, causing the dangerous animal
with sharp teeth to swim parallel to the cable. Confused by increasing loss of control of its muscles, the
shark suddenly changes its direction and heads seaward, away from the electric field.
In a test of the invisible new shark-repellent system, a cable was placed around a beach in St. Lucia
an island in the tropics. A protective net, which had been installed around the beach a long time ago to
keep sharks away from swimmers, was left in place during the experiment.
When the electric field was left on for more than a year and a half, no sharks were found in the net.
However, when the power was turned off, 89 sharks ended up in the net.
Using the electric-wall method instead of net to protect bathers would avoid the needless death of
many sharks, said biologists. Currentjy, thousands of sharks die each year when they become trapped
in protective nets that surround holiday resorts in Africa and Australia. About 10 to 15 humans are killed
by sharks annually.
B. Because the shark doesn"t want to eat the swimmers.
C. Because of some mysterious reason from the God.
D. Because there is an invisible electric field confusing the shark.
B. a new shark-repellent system
C. the electric field
D. an insulated cable
B. only when an insulated cable is buried on the bottom of the sea around a beach where people swim
C. only when an electric current is sent through the cable
D. only when the sharks are trapped in protective nets
B. This new kind of shark-repellent system will take the place of the protective nets.
C. Thousands of sharks die and about 10 to 15 humans are killed by sharks each year in Africa and
Australia since this new system was put into use.
D. Using the electric-wall method instead of nets to protect bathers would avoid the needless death of
many sharks.
beauties of nature. They can also bring things close that are far away. Through photos,people can see wild animals , cities in foreign lands , and even the stars in outer space. Photos also tell stories.
Reporting the news through photos is called photojoumalism. At times photojournalists tell their stories
through a single picture. At other times,they use a group of pictures to tell a story. Each picture is like a
chapter in a book,which can do more than record the facts. It can also be a strong force for social change.
Jacob Riis was among the first photojournalists. He took pictures of parts of New York City where the poor lived. Riis believed that poverty (贫穷) caused crime, and he used photos to help him prove his
point. A few years later,the photos of small children working in factories by Lewis Hine shocked the
public. Hine"s pictures helped bring about laws to protect such children.
Hundreds of pictures may have to be taken in order to get one or two really good photos. It takes
science to have the photo come out clearly and art to make a photo that has a good design and expresses
feeling. Photojournalists make an actual record of what they see. A photo, however,can be both a work of art and an actual record. It can record an important event as a beautiful or exciting picture.
As historical and artistic documents (文献), photos can become more important over time. Today
photojoumalists still have their pictures appear in newspapers and magazines. They also publish (发表)
them in books and on the Internet.

Only after a week"s leave-during which he read novels,listened to music and walked with his wife on a beach-was Rudenstine able to return to work.
In our modern life, we have lost the rhythm between action and rest. Amazingly, within this world there
is a universal but silly saying, "l am so busy. "
We say this to one another as if our tireless efforts were a talent by nature and an ability to successfully deal with stress. The busier we are, the more important we seem to ourselves and , we imaglne , to others. To be unavailable to our friends and family, and to be unable to find time to relax-this has become the
model of a successful life.
Because we do not rest,we lose our way. We miss the guide telling us where to go, the food providing us with strength , the quiet giving us wisdom.
How have we allowed this to happen? I believe it is this: we have forgotten the Sabbath, the day of the week-for followers of some religions-for rest and praying. It is a day when we are not supposed to work, a time when we devote ourselves to enjoying and celebrating what is
beautiful. It is a good time to bless our children and loved ones, give thanks.share meals, walk and sleep. It is a time for us to take a rest, to put our work aside, trusting that there are larger forces at work taking
care of the world.
Rest is a spiritual and biological need; however,in our strong ambition to be successful and care for our many responsibilities ,we may feel terrbly guilty when we take time to rest. The Sabbath gives us
permission to stop work. In fact, "Remember the Sabbath" is more than simply permission to rest; it is a
rule to obey and a principle to follow.
B. a warning of danger
C. a sign of age
D. a spread of disease
B. be more talented than other people
C. be more important than anyone else
D. be busy workingwithout time to rest
B. fail to realize that rest is an essential part of life
C. fail to realize that religions force them to rest
D. think that taking a rest means being lazy
B. The Sabbath gives us permission to rest.
C. It is silly for anyone to say "I am so busy."
D. We should be available to our family and friends.
suddenly stopped trying. He left school at 16 with only two scores for secondary school subjects.One
of the reasons that made it cool for him not to care was the power of his peer(同龄人) group.
The lack of right male(男性的 ) role models in many of their lives-at home and particularly in the
school environment(环境) --means that their peers are the only
people they have to judge themselves against.
They don"t see men succeeding in society so it doesn"t occur to them that chey could make something of themselves. Without male teachers as a role model, the effect of peer actions and street culture (文化)
is all-powerful. Boys want to be part of a club. However, schools can provide the environment for change, and provide the right role models for them. Teachers need to be trained to stop thal but not in front of a
child"s peers. You have to do it one to one, because that is when you see the real child.
It"s pointless sending a child home if he or she has done. wrong. They see it as a welcome day off to
watch television or play computer games. Instead, schools should have special unil where a child who has done wrong goes for the day and gets advice about his problems-somewhere he can work away from his peers and go home after the other children.
B. His parents no longer supported him.
C. lt"s cool for boys of his age not to care about studies.
D. There were too many subjects in his secondary school.
B. A special unit.
C. The student judges.
D. The horne environment.
B. Train leaders of their peer groups.
C. Stop the development of street culture.
D. Give them lessons in a separate area.
B. teaches the boy a lesson
C. sends the boy home as punishment
D. works together with another teacher
