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: it47

with a system in the body that uses enzymes (酶) 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 SARSbut also other diseases that can cause lung failure. These include avian flu (禽流感) and influenza in humans.

The first 52of SARS were discovered in Guangdong province, in southern China, in

November of 2002. SARSwas 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

To call something“marginal” means it is not very good. Farmers have their own way to

47marginal 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 excellent51 for grazing( 吃草 )animals like cattle,sheep and goats. Grass seed can be bought from a foreign supplier or52grasses 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.

B) priority G) adequate L) revealed

C) transplant H) transform M) prejudice

D) effective I) discouraging N) hazard

E) limited J ) quality O) recovered

China is casting such a huge shadow on the United States that many Americans are trying

hard to learn the Chinese language with an effort to keep their competitive edge.

"Interest in learning Chinese among American youth and their parents has grown 47 in

the past five years," said Vivien Stewart, vice president at the Asia Society, a US group trying to bridge the 48 between Americans and the peoples of Asia and the Pacific.

China's rapid progress is driving the interest to 49 the language, experts say. "The

Chinese rich cultural traditions and 50 economy mean that it is now essential for all of our students to be better prepared to engage them and seize opportunities together," said Michael

Levine, Asia Society' s executive director of education.

A 2004 College Board survey found that 2,400 high schools--an 51 number--would be

interested in 52 the Advanced Placement (AP) courses in Chinese language and culture when the courses become available in 2006.

China, the world' s most populous (人口稠密的) nation, is53 to the United States

because it is a leading trader, consumer and investor. It has 54 the United States as the

world's largest consumer and could become the second largest economy in the world, in the next

two to three decades.

Even though the US State Department has regarded the Chinese language extremely important to national prosperity , the" 55 conditions to support recruitment of students and teachers

as well as the growth of high quality programs is 56 inadequate,"an Asia Society study says.

B) automatically G) pursue L) scarcely

C) dramatically H) request M) current

D) important I) incredible N) offering

Can money buy happiness? Yes, 47 the authors of a new study---but only to a point.

Psychology has shown that richer people generally rank the overall quality of their lives

more 48 than poorer people do. At the same time, their actual happiness seems to be 49 less

by their ability to buy more than by being able to keep up with those with comparable resources

in their own age group.

"Our findings point to the possibility that, rather than promoting overall happiness,

continued income growth could 50 an ongoing consumption race where people have to consume

more and more, just to maintain a 51 level of happiness," writes Glenn Firebaugh of Pennsylvania State University.

The study was 52 at the American Sociological Association's 100th Annual Meeting.

Whether the rich are happier as a whole than their less 53 fellows is becoming an increasingly

hot topic for debate. Recent years have 54 many writings on the "science of happiness."

Richer people are happier because money can help purchase goods and services and it is the 55

of these materials that increases one's enjoyment of life and one's sense of well-being. Firebaugh and his colleagues measured the age, total family income, and general happiness of

56 aged 20 to 64, generally considered the working lifespan (工作寿命) for most Americans.

Regardless of such standards as physical health, education, and marital status (婚姻状况), people's happiness was affected by what others earned. The higher the income of others

in one's age group, the lower one's happiness.

A) constant F) consumption K) witnessed

B) wealthy G) consequently L) rejected

C) claim H) implement M) individuals

D) deny I) automatic N) favorably

E) motivated J) presented O) challenging

The more time children spend watching television the poorer they perform academically,

according to three studies published on Monday. 47 television viewing has been blamed for

increasing rates of childhood obesity (肥胖) and for aggressive behavior, while its48 on

schooling have been inconclusive, researchers said.

But studies published on the topic in this month' s Archives of Pediatrics (小儿科) & Adolescent Medicine concluded television viewing 49 to have an adverse effect (副作用) on academic pursuits.For 50 ,children who had televisions in their bedrooms--and 51 watched

more TV--scored lower on standardized tests than those who did not have sets in their rooms.

In contrast, the study found having a home computer with 52 to the Intemet resulted in

comparatively higher test scores.

"Consistently,those with a bedroom television but no 53 home computer had, on average, the lowest scores and those with home computer but no bedroom television had the highest scores," wrote study author Dina Borzekowski of Johns Hopkins University. The American Academy of

Pediatrics has 54parents to limit children’s television viewing to no more than one to

two hours per day--and to try to keep younger children away from TV altogether.

In two other studies published in the same journal, children who 55 watched television

before the age of 3 ended up with lower test scores later on, and children and adolescents who

watched more television were less 56 to go on to finish high school or earn a college degree.
