     The best thing you can say about the roofs of most city buildings is that you don't have
to look at them much. That's very good, since an urban landscape viewed from above can
be an unlovely thing-blockafterblockof tarred(鋪有瀝青的 ) black rooftops , stickyin
summer. windswept in winter and ugly year-round.Or at least that's the way it used to be.
     But urban roofs are going green. Fnvironmental designers have begun to realize that the
tops of buildings don't have to be wastelands. Indeed, they can be gardens, planted with
grasses,flowers and bushes.
     A planted roof usually comes in one of two varieties : extensive or intensive. The
extensive type is wide and shallow, with a soil depth of less than 8 inches, able to support
smaller plants. The intensive type may be smaller,but it's relatively deeper and home to
larger plants.
     Whatever the design,green roofs are not so simple as ordinary gardens. They have multiple
layers beneath the soil, including a drainagelayer , waterproofing , structuralsupport , andso on.
     But this system can do a great deal of good. A recent paper in the joumal BioScience
tells that green roofs can control temperature , contain water and clean the air. And most
impressively , they can cut heat loss from a building by 50% ,lower air-conditioning costs
by 25% , and reduce the urban-heated-island effect by 2℃.
     Of course,apart from the square feet greened and heat reduced. green roofs are even
more valued since people can gain some psychological comfort simply by having a quiet
place to go. As so often happens,what's good for the planet can also be good for the spirit.

     The storage of classified research at all 24 labs run by the US Department of Energy was shut down
this week after officials decided that the security problems recently found at the Los Alamos National
Laboratory in New Mexico might also exist elsewhere.
     Several computer disks went missing at Los Alamos earlier this month, forcing Energy Secretary
Spencer Ahraham to stop all work at the lab until the problems are found out. As of 26 July, two missing
disks had still not been found, and 15 employees had been suspended in connection with the
disappearance.
      Now all energy labs will stop doing classified research that involves (需要) removable storage
devices-such as computer disks-until all the devices are given explanation for and new procedures are
in place for monitoring their handling by laboratory employees.
      "While we have no evidence that the problems being investigated are present elsewhere . we  have
a responsibility to take all necessary action to prevent such problems,"Abraham said on 23 July.
     The shut-down isn't quite as dramatic (驚人的) as it sounds,expert say. Only two labs will be
seriously affected;Sandia National  Laboratory  in  Albuquerque, New  Mexico , and Lawrence
Livemore National Laboratory in Califomia. Together with Los Alamos,these two labs conduct the most
part of the country's nuclear weapon programmes. At Livermore, 876 employees will be suspended
during the storage of some 12,000 items of classified removable material.
      At other labs , far fewer people will  be affected. " The impact (影響) should be the smallest , "
says  Martha  Krebs , former director of the energy department's science office.
1. Why was the storage of classified research at all 24 labs shut down?
A. Because the security problems might be present elsewhere .
B. Because the security problems existed elsewhere.
C. Because two missing computer disks had still not be found.
D. Because officials decided to stop doing such research.
2. How many labs conduct the country's nuclear weapon programmes according to the text?
A. About 24.                  
B. Only 2.
C. More than 2.              
D. Over 15.
3. The underlined word "suspended" in the second paragraph probably means" _________". 
A. hung from above
B. stopped from holding a position
C. doubted
D. fired
4. It can be inferred from the text that________.  
A. the computer disks must have been stolen by terrorists
B. the people living in the United States have little security
C. the United States is a country whose security is very bad
D. the missing of the computer disks caused great fear among Americans

     If it works,it should make everyone feel a little better about healthcare and make healthcare a little
more accessible to more people. Patients will no longer have to shell out the 7 to 15 percent extra fees
that state-owned hospitals charge on medicines. The Health Ministry' announcement last week is a
welcome first step in China's long-delayed healthcare reform.
     The new policy, to be adopted on trial basis. Is intended to stop hospitals from relying too much on
income from medicines. It is estimated that income from the sale of medicines makes up 50 percent of
a hospital's revenue on an average. What is supposed to make the difference is the move's intention to
get rid of the unhealthy tendency of doctors prescribing expensive drugs for their own or their hospital's
profits rather than for the rehabilitation of patients. The government's good intention could be just wishful
thinking if no specific measures were taken to break the nexus between representatives of medicine
manufactures and doctors or between hospitals and manufacturers. It is an open secret that some doctors get kickbacks from drug manufacturers for prescribing their drugs.
      This move will undoubtedly dampen the enthusiasm hospitals have to urge their doctors to prescribe
expensive drugs.
     It is still too early to say how much the new policy will improve the service doctors provide to their
patients and reduce the cost of healthcare since it will only be practiced in some hospitals on a trial basis
for three years. Cutting down expensive healthcare bills and improving the quality of service require more
investigations into the problem areas of the healthcare system.
     Hopefully , this is just a start  that will  be followed up by more practical moves to make it easier and
cheaper for more people to get quality healthcare service.
1. What is the expected result of the new policy?
A. Hospitals will have more enthusiasm in prescribing expensive drugs.
B. Hospitals will have more enthusiasm in prescribing cheap drugs.
C. Patients will pay less and receive better service.
D. Doctors will not be able to get kickbacks from drug manufacturers any more.
2. What can be inferred from the passage? 
A. The new policy will be adopted in all hospitals.
B. The Health Ministry is not definitely sure whether the new policy will achieve expected result.
C. The cost of healthcare will drop the moment the policy is adopted.
D. Hospitals will suffer a lot as long as the policy is adopted.
3. What does the underlined word" nexus" ( Paragraph 2) probably mean?
A. Bad relationship.          
B. Good relationship.
C. Promise.                    
D. Management.
4. What is the best title for the passage?
A. A good first step in China's healthcare reform.
B. Less  cost,better service.
C. Good policy for hospitals.
D. China's healthcare system.

     In the summer of 1978 an English farmer was driving his tractor through a field of wheat when he
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 (點) . 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.
1. In the summer of 1978 , an English farmer discovered in his field that________.  
A. some of his wheat had been damaged
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
2. According to the text, the underlined part "a hoax" in paragraph 3 probably means ___________.   
A. an attempt made to fool people
B. a special way to plant crops
C. a research on the force of winds
D. an experiment for the protection of crops
3. Which of the following may prove that the crop circles were not made by man? 
A. The farmers couldn't step out of the field.
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.
4. That the crop circles are made by_______is probably true. 
A. air movement
B. airplane crashes
C. new farming techniques

     As kids, my friends and I spent a lot of time out in the woods.  " The  woods "  was  our  part-time  
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 (語氣)  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.
1. The author and his friends were often out in the woods to__________.  
A. spend their free time
B. play golf and other sports
C. avoid doing their schoolwork
D. keep away from their parents
2. What can we infer from Paragraph 2?   
A. The activities in the woods were well planned.
B. Human history is not the result of exploration.
C. Exploration should be a systematic activity.
D. The author explored in the woods aimlessly
3. The underlined word "skeptical"  in Paragraph 3 is closest in meaning to _________.    
A. calm    
B. doubtful    
C.serious    
D. optimistic
4. How does the author feel about his childhood?   
A. Happy but short.
B. Lonely but memorable.

     Pretoria, South Africa-Hundreds of swimmers play in the water along a South African beach.
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 (鯊魚成群的) shores. An electrical
engineer from the University of Pretoria has  developed  an  electrical  system  that  repels (擊退 )
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 (絕緣的)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.                        
1. Why doesn't the shark attack the swimmers according to the passage?
A. Because there are many swimmers in the water.
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.
2. An electrical engineer from the University of Pretoria has developed_________.
A. a protective net
B. a new shark-repellent system
C. the electric field
D. an insulated cable
3. An electric field is produced in the water above the cable_________. 
A. only when a shark swims into the electric field
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
4. Which of the following is NOT TRUE according to the passage?
A. Protective nets had been installed around the beach earlier than the new shark-repellent system.
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.

     Photographs are everywhere. They decorate(裝飾) the walls of homes and are used in stores for sales of different goods. The news is filled with pictures of fires, floods, and special events. Photos record the
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 (貧窮) 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 (文獻(xiàn)), photos can become more important  over time. Today
photojoumalists still have their pictures appear in newspapers and magazines. They also publish (發(fā)表)
them in books and on the Internet.
1. The underlined word "They"  in the first paragraph refers to _________.   
A. beauties    
B. photos    
C. goods    
D. events
2. The photos of the small children by Hine show us that photos _________.   
A. are also works of art
B. are popular ways of reporting news
C. often shock the public
D. can serve as a force for social change
3. What can we learn from the passage?  
A. News with pictures is encouraging.
B. Photos help people improve their life.
C. News photos mean history in a sense.
D. People prefer reading news with pictures.
4. The text is mainly about _________.   
A. telling the story through pictures
B. decorating the walls of homes
C. publishing historical papers
D. expressing feeling through pictures
