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 (惊人的) 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 (影响) should be the smallest , "
says Martha Krebs , former director of the energy department"s science office.
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.
B. Only 2.
C. More than 2.
D. Over 15.
B. stopped from holding a position
C. doubted
D. fired
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

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.
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.
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.
B. Good relationship.
C. Promise.
D. Management.
B. Less cost,better service.
C. Good policy for hospitals.
D. China"s healthcare system.

house.
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.
