Coral reefs are one of the most fragile, biologically

complex, and diverse marine ecosystem on Earth. This

ecosystem is one of the fascinating paradoxes of the bio-

sphere: how do clear, and thus nutrient-poor, waters sup-

(5) port such prolific and productive communities? Part of the

answer lies within the tissues of the corals themselves.

Symbiotic cells of algae known as zooxanthellae carry out

photosynthesis using the metabolic wastes of the coral

thereby producing food for themselves, for their corals,

(10) hosts, and even for other members of the reef community.

This symbiotic process allows organisms in the reef com-

munity to use sparse nutrient resources efficiently.

Unfortunately for coral reefs, however, a variety of

human activities are causing worldwide degradation of

(15) shallow marine habitats by adding nutrients to the (water.

Agriculture, slash-and-burn land clearing, sewage disposal

and manufacturing that creates waste by-products all

increase nutrient loads in these waters. Typical symptoms

of reef decline are destabilized herbivore populations and

(20)an increasing abundance of algae and filter-feeding

animals.

Declines in reef communities are consistent with observa-

tions that nutrient input is increasing in direct proportion to

growing human populations, thereby threatening reef com-

(25) munities sensitive to subtle changes in nutrient input to

their waters.

The passage is primarily concerned with______

A.describing the effects of human activities on algae in coral reefs

B.explaining how human activities are posing a threat to coral reef communities

C.discussing the process by which coral reefs deteriorate in nutrient-poor waters

D.explaining how coral reefs produce food for themselves

E.describing the abundance of algae and filter-feeding animals in coral reef areas

While there is no blueprint for transforming a largely

government-controlled economy into a free one, the

experience of the United Kingdom since 1979 clearly

shows one approach that works: privatization, in which

(5) state-owned industries are sold to private companies. By

1979, the total borrowings and losses of state-owned

industries were running at about t3 billion a year. By

selling many of these industries, the government has

decreased these borrowings and losses, gained over t34

(10) billion from the sales, and now receives tax revenues from

the newly privatized companies. Along with a dramatically

improved overall economy, the government has been able

to repay 12.5 percent of the net national debt over a

two-year period.

(15) In fact, privatization has not only rescued individual

industries and a whole economy headed for disaster, but

has also raised the level of performance in every area. At

British Airways and British Gas, for example, productivity

per employee has risen by 20 percent. At associated

(20) British Ports, labor disruptions common in the 1970’s and

early 1980’s have now virtually disappeared. At British

Telecom, there is no longer a waiting list—as there always

was before privatization—to have a telephone installed.

Part of this improved productivity has come about

(25) because the employees of privatized industries were given

the opportunity to buy shares in their own companies. They

responded enthusiastically to the offer of shares; at British

Aerospace, 89 percent of the eligible work force bought

shares; at Associated British Ports, 90 percent; and at

(30) British Telecom, 92 percent. When people have a personal

stake in something, they think about it, care about it, work

to make it prosper. At the National Freight Consortium,

the new employee-owners grew so concerned about their

company’s profits that during wage negotiations they

(35) actually pressed their union to lower its wage demands.

Some economists have suggested that giving away free

shares would provide a needed acceleration of the privati-

zation process. Yet they miss Thomas Paine’s point that

“what we obtain too cheap we esteem too lightly.” In

(40) order for the far-ranging benefits of individual ownership

to be achieved by owners, companies, and countries,

employees and other individuals must make their own

decisions to buy, and they must commit some of their own

resources to the choice.

According to the passage, all of the following were benefits of privatizing state-owned industries in the United Kingdom EXCEPT______

A.Privatized industries paid taxes to the government.

B.The government gained revenue from selling state-owned industries.

C.The government repaid some of its national debt.

D.Profits from industries that were still state-owned increased.

E.Total borrowings and losses of state-owned industries decreased.

第5题
In 1896 a Georgia couple suing for damages in the

accidental death of their two year old was told that since

the child had made no real economic contribution to the

family, there was no liability for damages. In contrast,

(5) less than a century later, in 1979, the parents of a three

year old sued in New York for accidental-death damages

and won an award of $750,000.

The transformation in social values implicit in juxta-

posing these two incidents is the subject of Viviana

(10) Zelizer’s excellent book, Pricing the Priceless Child.

During the nineteenth century, she argues, the concept

of the “useful” child who contributed to the family

economy gave way gradually to the present-day notion

of the “useless” child who, though producing no income

(15) for, and indeed extremely costly to, its parents, is yet

considered emotionally “priceless.” Well established

among segments of the middle and upper classes by the

mid-1800’s, this new view of childhood spread through-

out society in the iate-nineteenth and early-twentieth

(20) centuries as reformers introduced child-labor regulations

and compulsory education laws predicated in part on the

assumption that a child’s emotional value made child

labor taboo.

For Zelizer the origins of this transformation were

(25) many and complex. The gradual erosion of children’s

productive value in a maturing industrial economy,

the decline in birth and death rates, especially in child

mortality, and the development of the companionate

family (a family in which members were united by

(30) explicit bonds of love rather than duty) were all factors

critical in changing the assessment of children’s worth.

Yet “expulsion of children from the ‘cash nexus,’...

although clearly shaped by profound changes in the

economic, occupational, and family structures,” Zelizer

(35) maintains. “was also part of a cultural process ‘of sacral-

ization’ of children’s lives. ” Protecting children from the

crass business world became enormously important for

late-nineteenth-century middle-class Americans, she

suggests; this sacralization was a way of resisting what

(40) they perceived as the relentless corruption of human

values by the marketplace.

In stressing the cultural determinants of a child’s

worth. Zelizer takes issue with practitioners of the new

“sociological economics,” who have analyzed such tradi-

(45) tionally sociological topics as crime, marriage, educa-

tion, and health solely in terms of their economic deter-

minants. Allowing only a small role for cultural forces

in the form. of individual “preferences,” these sociologists

tend to view all human behavior. as directed primarily by

(50) the principle of maximizing economic gain. Zelizer is

highly critical of this approach, and emphasizes instead

the opposite phenomenon: the power of social values to

transform. price. As children became more valuable in

emotional terms, she argues, their “exchange” or “ sur-

(55) render” value on the market, that is, the conversion of

their intangible worth into cash terms, became much

greater.

It can be inferred from the passage that accidental-death damage awards in America during the nineteenth century tended to be based principally on the______

A.earnings of the person at time of death

B.wealth of the party causing the death

C.degree of culpability of the party causing the death

D.amount of money that had been spent on the person killed

E.amount of suffering endured by the family of the person killed
