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

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.

C. Only healthy people can immigrate into America.

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

A recent survey of teachers found that an unhealthy passion with celebrity culture is having a negative impact on British students’ studies and it discovered that celebrity couple, the Beckhams, are the favorites among most students. Many students are ignoring building their own careers to seek a chance at fame instead, the Association of Teachers and Lecturers (ATL) survey found.

Almost two-thirds of teachers said sports stars were the type of celebrity many pupils wanted to follow while more than half of students wanted to be pop stars.

The survey said the celebrities that students aspired to mostly were David and Victoria Beckham who live in Los Angeles now. Soccer player Beckham is on the top of the survey while in second place, with almost a third of the survey’s votes, was his 33-year-old pop star wife.

Almost half of the 300 teachers surveyed said pupils tried to look like or behave like the celebrities they most admired, with some girls even dressing "unsuitably".

"We are not surprised about the influence of celebrity culture in schools —it reflects the current media passion with celebrities and the effect of celebrity culture on society as a whole," ATL general secretary Mary Bousted said in a statement.

"Celebrities can have a positive effect on pupils. They can raise pupils’ aspirations and desires for the future. However, celebrity culture can spread the idea that celebrity status is the greatest achievement and reinforce the belief that other career choices are not as valuable," said one primary school teacher. "Too many of the pupils believe that school success is unnecessary, because they will be able to get fame and fortune quite easily through a reality TV show."

The story mainly tells us that ______.

  A. the Beckhams are mostly admired in Britain

  B. most students think that being pop stars is more valuable than other career achievements

  C. the celebrity passion has a harmful impact upon British students’ studies

  D. a survey was made recently about the popularity of the stars

According to the survey, Victoria Beckham ______.

  A. is a pop star most students admire

  B. goes in the second place of the celebrities admired

  C. won two-thirds of the votes

  D. lives in New York now

Why does the author mention that pupils tried to look like or behave like the celebrities they most admired, with some girls even dressing “unsuitably”?

  A. The pupils think it interesting to pretend to be the celebrities.

  B. The behavior or the dress of celebrities can be followed as examples.

C. The author wants to show the negative influence these celebrities had on the students.

D. The author just wants to show being pop stars is very valuable to the students.

What is not TRUE according to the story?

  A. Celebrities can’t have positive impact on the students.

  B. Beckham and Victoria are husband and wife.

C. The so-called celebrity culture does harm to the pupils’ ideas about achievement.

  D. Many students believe that school success is unnecessary.

Have you ever thought, “I wish I could take a year off and just travel around the world”? Well, three lucky American teenagers were able to do just that. The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.

This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.

Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored (赞助) this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.

The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.

As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions. They realized that each of them can make a difference.

These teenagers went on the journey around the world _____.

A. to experience the most serous environmental problems on the earth

B. to bring the kindness of America to the other parts of the world

C. to go on sightseeing around the world

D. to call on more teenagers to join Earthwatch Institute

What’s true about their journey?  

A. They had to pay for their journey on their own expense.

B. They often had to move from one hotel to another.

C. They had to take great pains to collect environmental information.

D. They received a warm welcome every time they arrived at a new place.

It can be inferred that Earthwatch Institute could be _____.

A. an international university that takes in students from all over the world

B. a TV station that makes programmes on the beautiful scenery of the earth

C. a travel agency that organizes adventure trips specially for school children

D. an organization that brings science to life for people concerned about earth’s environment

What did they these teenagers learn from the journey?

B. Long journey was not suitable for school children.

C. It should take the whole world to help the children.

D. Environmental problems can be solved if school children take part.

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. People with jet lag may feel extremely tired for several days. They may also have problems thinking clearly and remembering.

Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights The other half spent more than fourteen days in their home areas.

The researcher took some saliva from the women's mouths to measure levels of a hormone(荷尔蒙) that increases during stress (紧张). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain's temporal lobes (脑叶).

It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.

The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.

Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.

A. the women who have longer rest at home show better memory

B. the women who fly in short time have smaller right temporal lobes

C. the women who have longer flights fail the memory test

D. the women who rest more than 14 days produce less hormones
