Once


the


world


embraced


the


automobile,


the


days


of


depending


on


horses,


bicycles,


ferries,


and


trains


quickly slipped into the past. People were __47__ with the speed of the automobile but they were also enjoying


the personal freedom that the automobile gave them. Owning a car gave people the freedom to go anyplace a road


__48__. This allowed people to and at their own __49__. This independence gave the car a popular edge over


buses


and


trains.


The


popularity


of


the


automobile


made


it


the


__50__


of


the


transportation


system.


The


automobile changed our lives when it created a giant industry that offered more and more jobs. The automobile


made it possible for people to live in areas __51__ from their work place. This caused cities to grow and made


suburban


living


more


convenient.


Of


course,


with


more


places


to


go,


more


__52__


roads


had


to


be


built.


The


automobile caused a __53__ effect. Jobs increased, industries grew, new industries developed, and cities appeared.


Today


the

industry


continues

offer


many

Jobs


are


plentiful


in


this


industry


and


improvements continue to be made to the automobile with new technologies.



We have come a long way from that first __55__ carriage because of the cooperative efforts of many people


in the last century. It will be interesting to see what the future holds for the automobile. We have already seen

A


college


education


is


an


investment


in


the


future.


But


it


can


be


a



47



one.


The


College


Board



48



that the costs at a four-year public college in the United States increased 10% this past school year.



That was less


than


the


13%


increase


the


year


before,


but


still


much


higher


than


the


inflation




49




Public


colleges


and


universities still cost a lot less than private ones.








Financial


aid


often


helps.


But


financial


experts




50



parents


to


start


college


savings


plans


when


their


child is Still very young.







All fifty states and the District of Columbia



51



what are called 5-29 plans. These plans are named after


the part of the federal tax law that created them in 1996. States use private investment companies to operate the




52



of the programs.








Every state has its own rules




53



5-29 plans. Some of the plans are




54



of state taxes. And all are


not required to pay federal taxes. However, the government could start to tax withdrawals in 2011 if Congress


does not change the law.







5-29 plans include investment accounts that increase or decrease in value with the investments they contain.


Families must decide how




55



they want to put money into stocks, or other investments.







Another kind of 5-


29 plan lets parents begin to pay for their child’s education in

There


is


progress


toward


a


possible


treatment


for


lung


diseases


such


as


SARS


(severe


acute


respiratory


syndrome).



Researchers


have


learned


more


about how


the


SARS


virus


works:


it




47



with a


system


in


the


body


that


uses


enzymes


(



)


to


control


blood


pressure


and


fluid


balance.


Scientists


say


the


virus



48



to


an


enzyme known as ACE-two. The virus blocks the enzyme, permitting fluid to enter the lungs.


A


team


from


Europe


and


Asia


reported


the




49



in


Nature


Medicine.



Doctor


Josef


Penninger


of


the


Institute of Molecular Biotechnology in the Austrian Academy of Sciences was the




50



writer of the report.


The discovery could lead to a new




51



of treating not just SARS but also other diseases that can cause lung


failure. These include avian flu (


禽流感


) and influenza in humans.








The first




52




of SARS were discovered in Guangdong province, in southern China, in November of


2002. SARS was not



53



as a worldwide threat until March of 2003. The disease spread to 26 countries, most


of them in the Asia-Pacific area. An estimated 8, 000 people had SARS. More than 770 of them died, or about


10% , a



54



high rate.


The


World


Health


Organization


warned


people


not


to


travel


to



55



areas.


The



56



hurt


international


travel and business. The WHO says the disease stopped spreading by July of 2003. As a result of SARS, the health


agency got new powers to act before a government officially announces a crisis.



A) means


















F) associates














K) optimistically






















B) alternative














G) major


















L) identified


C ) attaches
















H) awful


















M) interferes


D) crisis


















I) relatively
















N) distributed


E) cases


















J) findings

















O) affected

To call something



marginal


means it is not very good. Farmers have their own way to



47



marginal


land: It is the last to be planted under good conditions, and has the



48



to be avoided under poor conditions.


Low



49



soil is not the only reason land could be considered marginal. It might be in an area where rainfall is




50



or where a hillside might rise too steeply.









There are uses for marginal land, however. Most often it is used as grassland.



Grasses provide excellent



51



for grazing (


吃草


) animals like cattle, sheep and goats.



Grass seed can be bought from a foreign supplier or



52



grasses


can


be


used.


However,


using


marginal


land


for


grazing


is


not


a


simple


issue.


There


is


a



53



of


overgrazing. Cattle can damage the crops by eating down to the roots. Also, the weight of the animals crushes the


soil and can make it too hard for growing. A(n)



54



way to reduce the harm is to move animals from one field


to


another.


This


method


is


known


as


rotational


grazing


(


循环放牧


)


which


is


extremely


important


for


marginal


land.








Another use for marginal land is for tree crops. Studies have



55



that the white pine and loblolly pine


(


火炬松


)


are


two


kinds


of


trees


that


grow


well


on


such


land.


They


grow


fast


and


provide


good


quality


wood.



Another tree is the poplar (


白杨



), found in many parts of the world.








Failure


to


take


the


care


needed


to


protect


marginal


lands


can


make


a


bad


situation


worse.


But


good


planning can



56



a marginal resource into a highly productive one.


A) feed
























F) define























K) native


B) priority





















G) adequate





















L) revealed


C) transplant



















H) transform





















M) prejudice


D) effective




















I) discouraging



















N) hazard


E) limited






















J ) quality






















O) recovered
