A research by the National Center for Health Statistics is seen as an important confirmation of the“Hispanic mortality paradox(西班牙裔死亡率悖論).”

On average,Hispanics outlive whites by 2.5 years and blacks by 7.7 years. Their life expectancy at birth in 2006 was 80.6 years,compared with 78.1 for whites,72.9 for blacks and 77.7 years for the total population.

The report shows that the Hispanic population has higher life expectancy at birth and at almost every age despite a socioeconomic status lower than that of whites.“Mortality is very correlated with income,education and health care access,”says Elizabeth Arias,author of the report.“You would expect the Hispanic population would have higher mortality,”in line with the black population.

The Hispanic paradox has been documented for more than two decades,but this is the first time the government has had enough data to issue national numbers. Researchers are struggling to explain why Hispanics live longer.

“We don’t know,”says David Hayes-Bautista,director of the Center for the Study of Latino Health and Culture at UCLA’s David Geffen School of Medicine.“We thought it was a problem in the data,but we can pretty much say this is real.”

Potential factors:

·Culture and lifestyle.  Support from extended family and lower rates of smoking and drinking.Latino groups in particular have very strong family and social ties.

·Migration.  The“healthy migrant effect”argues that healthy people are more likely to emigrate. And when immigrants become ill,they might return home and die there.

    Solving the puzzle may help the nation deal with health care issues because Hispanics use health services less—they make fewer doctors visits and spend less time in hospitals,Hayes-Bautista says.“It’s clearly something in the Latino culture,”he says.

In 2006,Hispanics’life expectancy is           years longer than the average of the total population.

    A. 2.5                 B. 7.7               C. 2.9              D. 80.6

What does the underlined word“outlive”in the second paragraph probably mean?

A. To live longer than…                      B. To live shorter than…

C. To die out.                              D. To expect to live.

What is the main idea of paragraph three?

A. Hispanics were born better than whites.

B. Morality is closely related with health care access.

C. Whites should have longer life expectancy.

D. Even experts can’t explain the phenomenon.

What is Mr.Hayes-Bautista’s opinion about the paradox?

A. He supports there is a problem with the data.

B. He intends to trust the cultural factor.

C. He believes in the“healthy migrant effect”.

D. He thinks health care the most important factor.

Which of the following inferences is true according to the passage?

A. Black people suffer the lowest social status in America.

B. Hispanics might have healthier ways of life.

C. Only healthy people can immigrate into America.

D. White people don’t have strong family ties.

三、閱讀理解(共20小題;每小題2分,滿分40分)

請閱讀下列短文,從每題所給的四個選項(A, B, C和D)中,選出最佳選項,并在答題卡上將該選項的標號涂黑。

When I get off the bus, I’m usually greeted by the sounds of news on CNN. My father welcomes me, and I help him with the usual things—changing the channel and some other tasks. My father has a disease that makes him unable to walk. Despite his disability, my father has always been my role model.

In my first year at middle school, my grades slipped greatly. My father told me I could improve. I currently maintain a B plus average, and he confidently supports me in all my academic efforts. He is against violence to the best of his ability. Love is his most important tool,and he makes sure we know that violence is never the answer.

He urges me not to fear,but to believe in what I think is right.“No matter what anyone tells me,”he says,“I believe what I choose. If someone is discriminating against you for who you are, they don’t deserve your time.”My friends are the most caring people I’ve met, because I realize that they don’t judge me, and they like me as I am.

I’ve always found it strange that people pity me because of my father’s condition. He’s not inferior(次于) to anyone. His disease doesn’t hold him back. He’s normal person.

When I see disabled people out in public, I consider them equal to any other individual. No one is superior to anyone for any physical reason. I’ve known that from that day on, thanks to my dad.

“Anything else?”I’ll ask.

“No, that’s fine.”

As I walk to my room, I think my dad who teaches me the most important things I’ll ever need to know. My father is in no way inferior to anyone else. If anything, he’s even better.

請認真閱讀下列短文,并根據(jù)所讀內(nèi)容在文章后表格中的空格里填入最恰當?shù)膯卧~。

注意:每空格1個單詞。

D. R. Gaul Middle School is in Union, Maine, a blueberry-farming town where the summer fair finds kids competing in pig scrambles and pie-eating contests.

Gaul, with about 170 seventh- and eighth-graders, has its own history of lower level academic achievement. One likely reason: Education beyond the basic requirements hasn't always been a top priority for families who've worked the same land for generations. Here, few adults have college degrees, and outsiders (teachers included) are often kept at a respectful distance.

Since 2002, Gaul's students have been divided into four classes, each of them taught almost every subject by two teachers. The goal: To find common threads across disciplines to help students create a big picture that gives fresh meaning and context to their classwork -- and sparks motivation for learning.

Working within state guidelines, each team makes its individual schedules and lesson plans, incorporating non-textbook literature, hands-on lab work and field trips. If students are covering the Civil War in social studies, they're reading The Red Badge of Courage or some other period literature in English class. In science, they study the viruses and bacteria that caused many deaths in the war.

Team teaching isn't unusual. About 77 percent of middle schools now employ some form of it, says John Lounsbury, consulting editor for the National Middle School Association. But most schools use four- or five-person teams, which Gaul tried before considering two-person teams more effective. Gaul supports the team concept by "looping" classes (跟班) so that the same two teachers stick with the same teens through seventh and eighth grades. Combining teams and looping creates an extremely strong bond between teacher and student. It also, says teacher Beth Ahlholm, "allows us to build an excellent relationship with parents."

Ahlholm and teammate Madelon Kelly are fully aware how many glazed looks they see in the classroom, but they know 72 percent of their eighth-graders met Maine's reading standard last year -- double the statewide average. Only 31 percent met the math standard, still better than the state average (21 percent). Their students also beat the state average in writing and science. And in2006, Gaul was one of 47 schools in the state to see testing gains of at least 20 percent in four of the previous five years, coinciding roughly with team teaching's arrival.

A town in Oxfordshire has become the first in the UK to have biomethane(生物甲烷)gas from human waste piped to their homes for gas central heating and cooking.

Up to 200 families in Didcot now receive the gas via the national gas power system. Head of energy and technology at British Gas, Martin Orrill, said customers wouldn’t notice any difference as the gas is purified(提煉)to the highest standard and has no smell. The gas is produced at a sewage(污物)treatment works plant in Didcot.

The entire process takes only less than three weeks, with the sewage being collected and sent first to settlement tanks. The solid waste material is then fed into digesters, where anaerobic bacteria(厭氧菌)digest the sewage, with the aid of enzymes(酶)to speed up the process. The digestion process produces methane, which can be burned to drive machines to produce electricity, or can be purified and fed into the gas network and piped to homes and businesses. British Gas says supplying the gas rather than electricity is far more efficient since around two-thirds of the energy is lost in producing electricity.

Partners in the Didcot project, British Gas, Scotia Gas Networks, and Thames Water, all hope to expand the process to other towns, and other companies such as Ecotricity and United Utilities have also announced biomethane projects being planned. One of these projects, in Manchester, could be supplying 500 homes with biomethane by mid next year. Another British Gas project in Suffolk will provide gas from digestion of brewery wastes to around 235 families.

The Didcot project cost £2.5m and was influenced by promises of government aids aimed at encouraging companies to develop renewable technologies. An EU directive means the UK must ensure at least 15 percent of its energy is from renewable sources by 2020.

    The UK produces about 1.73 million tons of sewage annually. If all sewage treatment works in the UK were fitted with the technology, they could supply gas for up to 350,000 families.

1.Which of the following is true of the biomethane gas?

   A. It’s mainly made from rotting plants.

   B. It’s an environmentally friendly gas.

   C. Its production process is too long.

   D. It’s easily recognized by the customers.

2.What is the function of the enzymes?

   A. To digest the solid waste material.

   B. To help get rid of anaerobic bacteria.

   C. To help purify the biomethane.

   D. To speed up the digestion process.

3.According to British Gas, the biomethane gas had better be used _____.

   A. as the power for the vehicles                                   

   B. for the heating and cooking

   C. to produce the electricity                                          

   D. to drive a variety of machines

4.The last three paragraphs mainly show that _____.

   A. UK government supports the biome thane projects

   B. the biome thane projects are very costly

   C. the biome thane projects still face many barriers

   D. the biome thane projects are promising

5.What should the text belong to?

   A. Computer science.                  B. Engineering.         C. Energy.                  D. Business.
