How Long Can People Live?

  She took up skating at age 85,made her first movie appearance at age 114,and held a concert in the neighborhood on her 121 st birthday.

  When it comes to long life,Jeanne Calment is the world's recordholder.She lived to the ripe old age of 122,so is 122 the upper limit to the human life span(寿命)?If scientists come up with some sort of pill or diet that would slow aging,could we possibly make it to 150— or beyond?

  Researchers don't entirely agree on the answers.“Calment lived to 122,so it wouldn't surprise me if someone alive today reaches 130 or 135,”says Jerry Shay at the University of Texas.

  Steve Austad at the University of Texas agrees.“People can live much longer than we think,”he says.“Experts used to say that humans couldn't live past 110.When Calment blew past that age,they raised the number to 120.So why can't we go higher?”

  The trouble with guessing how old people can live to be is that it's all just guessing.“Anyone can make up a number,”says Rich Miller at the University of Michigan.“Usually the scientist who picks the highest number gets his name in Time magazine.”

  Won't new anti-aging techniques keep us alive for centuries?Any cure,says Miller,for aging would probably keep most of us kicking until about 120.Researchers are working on treatments that lengthen the life span of mice by 50 percent at most.So,if the average human life span is about 80 years,says Miller,“Adding another 50 percent would get you to 120.”

  So what can we conclude from this little disagreement among the researchers?That life span is flexible(有弹性的),but there is a limit,says George Martin of the University of Washington.“We can get flies to live 50 percent longer,”he says.“But a fly's never going to live 150 years.”Of course,if you became a new species(物种),one that ages at a slower speed,that would be a different story,he adds.

  Does Martin really believe that humans could evolve(进化)their way to longer life?“It's pretty cool to think about,”he says with a smile.

More Than a Ride to School

  The National Education Association claims, "The school bus is a mirror of the community." They further add that, unfortunately, what appears on the exterior (外部) does not always reflect the reality of a chosen community. They are right---sometimes it reflects more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl.

  Bruce Hardy, school bus driver for Althouse Bus Company, has been Liesl's bus driver since kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus.

  This year Liesl is a senior and will enjoy her last year riding the bus. She says, "It's been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you're a child, adults do not think that what you have to say is important. Mr Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfe agree.

  Bruce Hardy has been making Octorara students feel special since 1975. This year he wifl celebrate 30 years working for Althouse Bus Company. Larry Althouse, president of the company acknowledges Bruce Hardy's outstanding record: "You do not come by employees like Bruce these days. He has never missed a day of work and has a perfect driving record He was recognized in 2000 by the Pennsylvania School Bus Association for driving 350 000 accident free miles. Hardy's reputation is made further evident through the relationships he has made with the students that ride his bus."

  Althouse further adds, "Althouse Bus Company was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come."

  Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl's mother Carol also enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.

(1) The underlined word "mirror" in the first line could be best replaced by ________.

[  ]

A.vehicle
B.device
C.need
D.reflection

(2) Bruce Hardy has been working with Althouse Bus Company ________.

[  ]

A.for 30 years
B.for 70 years
C.since last year
D.since 2000

(3) Which of the following statements is NOT true of Bruce Hardy?

[  ]

A.He is popular with his passengers.

B.He has never missed a day of work.

C.He is an impatient person.

D.He has driven 350 000 accident free miles.

(4) Althouse Bus Company was founded by ________.

[  ]

A.Larry Althouse
B.Althouse's grandfather
C.Liesl's mother
D.Ashley Batista

(5) Althouse Bus Company pays much attention to ________.

阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳答案。

  What makes a person a scientist? Does he have waysor tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools which makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate (调查), how to discover infomation, is important to everyone. The scientist, however, goes one step further; he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions into a large set of ideas about how the world works.

  The scientist's knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, Who developed the theory of relativity, arrived at this theory through mathematics. The accuracy (正确性) of his mathematics was later tested through investigations. Einstein's ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

1.What makes a scientist according to the passage?

[  ]

A.The tools he uses.

B.His ways of learning.

C.The way he uses his tools.

D.The various tools he uses.

2.“Knowing how to investigate, how to discover information, is important to everyone.” The author says this to show ________.

[  ]

A.the importance of information

B.the importance of thinking

C.the difference between scientists and ordinary people

D.the difference between carpenters and ordinary people

3.A sound scientific theory should be one that ________.

[  ]

A.works under one set of conditions at one time and also works under the same conditions at other times

B.leaves no room for improvement

C.does not allow any change even under different conditions

D.can be used for many purposes

4.What is the main idea of the passage?

[  ]

A.Scientists are different from ordinary people.

B.The theory of relativity.

C.Exactness is the core (核心) of science.

D.Exactness and way of using tools are the key to the making of a scientist.

阅读下面短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

  When one person gains weight, their close friends often follow.Researchers have just offered evidence in a study that says obesity(肥胖)appears to spread through society.But the findings might also offer hope.

  If friends help make obesity acceptable, then they might also be influential in losing the fat.

  The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism(酗酒).

  The findings appeared in the New England Journal of Medicine.The researchers used information collected from 12,000 people.It was collected between 1972 and 2003 as part of the Framingham Heart Study.

  The information was highly detailed.There was even contact information for close friends of the people in the study.

  The researchers examined more than 40,000 social ties.They found a person's chances of becoming severely overweight increased by 50% if a friend had become obese.

  A sister or brother of a person who became obese had a 40% increased chance of becoming obese.The risk for a wife or husband was a little less than that.Nicholas Christakis of Harvard Medical School was a lead researcher in the study.He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend.

  The study found that the sex of the friends was also an influence.In same-sex friendship, a person had a 71% increased risk of becoming obese.Men had a 44% increased risk of becoming obese after weight gain in a brother.In sisters, it was 67%.

  The researchers also considered the effect of where people lived in relation to each other.James Fowler of the University of California was the other lead expert.He says a friend who lives a few hundred kilometers away has as much influence as one in the same neighborhood.He says the study demonstrates the need to consider that a major part of people's health is tied to their social connections.

  Both researchers say their research shows that obesity is not just a private medical issue, but also a public health problem.
