to look at them much. That"s very good, since an urban landscape viewed from above can
be an unlovely thing-blockafterblockof tarred(铺有沥青的 ) 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.

Whatever the reason, you can soon become totally __2_ your surroundings. The desire to _3_ a
book with attractive" dust-jack" (封面 ) is irresistible (不可抵抗的) although this method of selection
ought not to be __4__ ,as you might end up with a rather __5__book. You soon become absorbed in
some book or _6_ ,and usually it is only much later that you realize you have spent far too much time
__7_ , and must dash off to keep some forgotten appointments without buying a book, __8__ .
This opportunity to escape the realit es of everyday life is,l think,the main __9 of a bookshop. There are not many places where it is possible to do this. A music shop is very much like a bookshop. You can _10 such places to your heart"s content. If it is a good shop, __11_assistant will approach you with
inevitable (必不可少的) greeting : " Can I help you , sir?" You needn"t buy anything you don"t want. In a
bookshop an assistant _12_ remain in the background until you have finished browsing. Then,and
13 ,are his services necessary. Of course you may want to find out where a particular section is,but
when he or she has led you there ,the assistant should _ 14 carefully and look as if he or she is not
interested in selling a __15_ book.
You have to be careful not to be attracted by variety of books in a bookshop. It is very __16 to
enter the shop looking for a book on ancient coins and to come out carrying a copy of the latest
best-selling novel and perhaps a book about brass-rubbing-something that had __17_vaguely (含糊的 )
interested you up until then. This volume on the subject,however, __18_ be so well illustrated and the part of the text you read proved so interesting that you just had to buy it. This sort of thing can be very
dangerous. _ 19_ running up a huge account,you can __20_a great deal of time wandering from section to section.

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.
