Part


II
































Reading


Comprehension

























(35


minutes)



Direction:







There are 4 passages in this part. Each passage is followed by some


questions or unfinished statements. For each of them there are four choices marked A),


B) C) and D). You should decide on the best choice and mark the corresponding letter


on the Answer Sheet with a single line through the center.






Passage One



Questions 21 to 25 are based on the following passage:












In the 1920s demand for American farm products fell, as European countries


began to recover from World War I and instituted austerity


(紧缩)


programs to reduce their imports. The result was a sharp drop in farm prices.


This


period


was


more


disastrous


for


farmers


than


earlier


times


had


been,


because


farmers


were


no


longer


self-sufficient.


They


were


paying


for


machinery,


seed,


and


fertilizer, and they were also buying consumer goods. The prices of the items farmers


bought


remained


constant,


while


prices


they


received


for


their


products


fell.


These


developments were made worse by the Great Depression, which began in 1929 and


extended throughout the 1930s









In


1929,


under


President


Herbert


Hoover,


the


Federal


Farm


Board


was


organized. It established the principle of direct interference with supply and demand,


and it represented the first national commitment to provide greater economic stability


for farmers.









President Hoover



s successor attached even more importance to this problem.


One of the first measures proposed by President Franklin D. Roosevelt when he took


office in 1933 was the Agricultural Adjustment Act, which was subsequently passed


by


Congress.


This


law


was


declared


unconstitutional


by


the


Supreme


Court


on


the


grounds that general taxes were being collected to pay one special group of people.


However, new laws were passed immediately that achieved the same result of resting


soil and providing flood-control measures, but which were based on the principle of


soil conservation. The Roosevelt Administration believed that rebuilding the nation



s


soil


was


in


the


national


interest


and


was


not


simply


a


plan


to


help


farmers


at


the










免费?宅在家学英语?怎么报名?



expense of other citizens.


Later the government


guaranteed loans to farmers so that


they could buy farm machinery, hybrid


(杂交)


grain, and fertilizers.

Supreme


Court


rejected


the

Adjustment Act because it believed that the Act ______________.














A



might cause greater scarcity of farm products



B



didn



t give the Secretary of Agriculture enough power



C



would benefit neither the government nor the farmers



D



benefited one group of citizens at the expense of others



请选择答案:

was


claimed


that

laws


passed


during


the


Roosevelt Administration were aimed at _______________.







A



reducing the cost of farming

conserving soil in the long-term interest of the nation



C



lowering the burden of farmers

helping farmers without shifting the burden onto other taxpayers

A:B:C:D:Passage Two







Questions 26 to 30 are based on the following passage:


















In the 1950s, the pioneers of artificial intelligence (AI) predicted that, by the


end of this century, computers would be conversing with us at work and robots would


be performing our housework. But as useful as computers are, they



re nowhere close


to


achieving


anything


remotely


resembling


these


early


aspirations


for


humanlike


behavior.


Never


mind


something


as


complex


as


conversation:


the


most


powerful


computers struggle to reliably recognize the shape of an object, the most elementary


of tasks for a ten-month-old kid.









A


growing


group


of


AI


researchers


think


they


know


where


the


field


went


wrong.


The


problem,


the


scientists


say,


is


that


AI


has


been


trying


to


separate


the


highest,


most


abstract


levels


of


thought,


like


language


and


mathematics,


and


to


duplicate them with


logical,


step-by-step programs.


A new movement


in


AI, on the


other hand, takes a closer look at the more roundabout way in which nature came up


with


intelligence.


Many


of


these


researchers


study


evolution


and


natural


adaptation


instead


of


formal


logic


and


conventional


computer


programs.


Rather


than


digital


computers


and


transistors,


some


want


to


work


with


brain


cells


and


proteins.


The


results


of


these


early


efforts


are


as


promising


as


they


are


peculiar,


and


the


new


nature-based AI movement is slowly but surely moving to the forefront of the field.









Imitating


the


brain



s

neural


(神经的)


network


is


a


huge


step


in


the


right


direction, says computer scientist and biophysicist Michael Conrad, but it still misses


an important aspect of natural intelligence.



People tend to treat the brain as if it were


made


up


of


color-coded


transistors,




he


explains,



but


it



s


not


simply


a


clever


network of switches. There are lots of important things going on inside the brain cells


themselves.




Specifically, Conrad believes that many of the brain



s capabilities stem


from


the


pattern-recognition


proficiency


of


the


individual


molecules


that


make


up


each


brain


cell.


The


best


way


to


build


an


artificially


intelligent


device,


he


claims,


would be to build it around the same sort of molecular skills.











免费?宅在家学英语?怎么报名?









Right


now,


the


notion


that


conventional


computers


and


software


are


fundamentally


incapable


of


matching


the


processes


that


take


place


in


the


brain


remains controversial. But if it proves true, then the efforts of Conrad and his fellow


AI rebels could turn out to be the only game in town.

A:B:C:D:Passage Three







Questions 31 to 35 are based on the following passage:


















Cars


account


for


half


the


oil


consumed


in


the


U.S.,


about


half


the


urban


pollution and one fourth the greenhouse



(温室)


gases. They take a similar toll of


(损耗)


resources in other industrial nations


and in the cities of the developing world. As vehicle use continues to increase in the


coming decade, the U.S. and other countries will have to deal with these issues or else


face unacceptable economic, health-related and political costs. It is unlikely that oil


prices will remain at their current low level or that other nations will accept a large


and growing U.S. contribution to global climatic change.










免费?宅在家学英语?怎么报名?









Policymakers and industry have four options: reduce vehicle use, increase the


efficiency


and


reduce


the


emissions


of


conventional


gasoline- powered


vehicles,


switch to less harmful fuels, or find less polluting driving systems. The last of these-in


particular the introduction of vehicles powered by electricity



is ultimately the only


sustainable option. The other alternatives


are


attractive in


theory but


in


practice


are


either impractical or offer only marginal improvements. For example, reduced vehicle


use could solve traffic problems and a host of social and environmental problems, but


evidence from around the world suggests that it is very difficult to make people give


up


their


cars


to


any


significant


extent.


In


the


U.S.,


mass-transit


tidership


and


carpooling



(合伙用车)


have declined since World War II. Even in western Europe, with fuel


prices averaging more than $$1 a liter (about $$4 a gallon) and with easily accessible


mass transit and dense populations, cars still account for 80 percent of all passenger


travel.








Improved


energy


efficiency


is


also


appealing,


but


automotive


fuel


economy


has


barely


made


any


progress


in


10


years.


Alternative


fuels


such


as


natural


gas,


burned in internal-combustion engines, could be introduced at relatively low cost, but


they


would


lead


to


only


marginal


reductions


in


pollution


and


greenhouse


emissions


(especially because oil companies are already spending billions of dollars every year


to develop less polluting types of gasoline).

use


in


western


Europe.



B



Car are popular in western Europe even though fuel prices are fairly high.



C



The reduction of vehicle use is the only sustainable option in densely populated


western Europe.



D



Western European oil companies cannot sustain the cost of developing new-type


fuels.

Questions 36 to 40 are based on the following passage:











免费?宅在家学英语?怎么报名?


















Reebok


executives


do


not


like


to


hear


their


stylish


athletic


shoes


called



footwear for yuppies



(雅皮士,


少壮高薪职业人士)



. They contend that Reebok shoes appeal to diverse


market segments, especially now that the company offers basketball and children



s


shoes


for


the


under-18


set


and


walking


shoes


for


older


customers


not


interested


in


aerobics


(健身操)


or


running.


The


executives


also


point


out


that


through


recent


acquisitions


they


have


added


hiking


boots,


dress


and


casual


shoes,


and


high-performance athletic footwear to their product lines, all of which should attract


new and varied groups of customers.








Still, despite its emphasis on new markets, Reehok plans few changes in the


upmakeret


(高档消 费人群的)


retailing network that helped push sales to $$1 billion


annually,


ahead


of


all


other


sports


shoe


marketers.


Reebok


shoes,


which


are


priced


form $$27 to $$85, will continue to be sold only in better specialty, sporting goods, and


department stores, in accordance with the company



s view that consumers judge the


quality of the brand by the quality of its distribution.









In the past few years, the Massachusetts-based company has imposed limits on


the number of its distributors (and the number of shoes supplied to stores), partly out


of necessity. At times the unexpected demand for Reebok



s exceeded supply, and the


company


could


barely


keep


up


with


orders


from


the


dealers


it


already


had.


These


fulfillment problems seem to be under control now, but the company is still selective


about its distributors. At present, Reebok shoes are available in about five thousand


retail stores in the United States



.








Reebok


has


already


anticipated


that


walking


shoes


will


be


the


next


fitness- related craze, replacing aerobics shoes the same way its brightly colored, soft


leather


exercise


footwear


replaced


conventional


running


shoes.


Through


product


diversification


and


careful


market


research,


Reebok


hopes


to


avoid


the


distribution


problems Nike came across several years ago, when Nike misjudged the strength of


the aerobics shoe craze and was forced to unload huge inventories of running shoes


through discount stores.

that

A



the quality of a brand is measured by the service quality of the store selling it



B

C

D
