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 . Halt 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 (唾液) from the women’s mouths to measure levels of a hormone (荷尔蒙) that increases during stress . 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 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 affect memory .

At a computer exhibition Bill Gates reportedly compared the computer industry with the auto industry and stated : “If GM had kept up with technology like the computer industry has ,we would all be driving twenty-five dollar cars that got 1,000 miles to the gallon.”

In response to ‘Bill’s comments , General Motors announced a news release stating :

If GM had developed technology like Microsoft , we would be driving cars with the following characteristics :

1. For no reason your car would crash twice a day .

2. Every time they repainted the lines on the road you would have to buy a new car .

3. Sometimes your car would die on the freeway for no reason and you would just accept this , restart and drive on .

For an increasing number of students at American universities , Old is suddenly in . The reason in clear : the aging of America means jobs . Besides the aging of the body―boom (生育高峰) population , a longer life means that the nation’s elderly population is certain to grow greatly over the next 50 years . By 2050, 25 percent of all Americans will be older than 65 , up from 14 percent in 1995. The change causes some questions for government and society , of course . But it also creates jobs in medicine and health fields , and in law and business as well. “Besides the doctors , we’re going to need more sociologists , biologists , city planners and lawyers,” says Professor Edward Schneider of the University of Southern California’s (USC) School of Gerontology (老人学).

Lawyers can major in “elder law” , which covers everything including nursing-home abuse (虐待) and age discrimination . Businessmen see huge opportunities in the elder market because the baby boomers , 74 million strong , are likely to be the wealthiest group of retires in human history. “Any student who combines an expert knowledge in gerontology with , say , an MBA or law degree will have a license to print money,” one professor says .

Margarite Santos is a 21-year-old senior at USC. She began college as a biology major but found she was “really bored with biology”. So the took a class in gerontology and discovered that she liked it . She says, “I did volunteer work in retirement homes and in was very satisfying.”

       B.gerontorogy has suddenly become popular

       C.more elderly professors are found in American colleges

       B.The volunteer workers in retirement homes

       C.College graduates with an MBA or law degree .

Education is not an end , but a means to an end . In other words , we do not educate children only for the purpose of educating them . Our purpose is to fit them for life .

In some modern countries it has for some time been fashionable to think that by free education for all whether rich or poor , clever or stupid-one can solve all the problems of society and build a perfect nation . But we can already see that free education for all is not enough ; we find in such countries a far larger number of people with university degrees , they refuse to do what they think “low” work , and , in fact , work with hands is thought to be dirty and shameful in such countries . But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor , we can live without education, but we would die if we have no food . If no one cleaned our streets and tooled the rubbish away from our houses , we should get terrible diseases in our towns …

In fact , when we say that all of us must be educated to fit us for life , it means that we must be educated in such a way that , firstly , each of us can do whatever work suited to his brains and ability and , secondly , that we can realize that all jobs are necessary to society , and that is very bad to be ashamed of one’s work . Only such a type of education can be considered valuable to society .

 

45.The writer of this passage thinks that        .

       A.education can settle all of the world’s problems

       B.free education for all probably leads to a perfect world

       C.free education won’t help to solve social problems

       D.all the social problems can’t be solved by education

46.The writer wants to prove that        .

       A.our society needs all kinds of jobs

       B.our society needs free education for all

       C.a farmer is more important than a professor

       D.people with university degrees refuse to do what they think “low” work

47.The purpose of education is        .

       A.to choose the system of education

       B.to prepare children mainly for their future work

       C.to let everyone receive education fit for him

       D.to build a perfect world

I used to be ashamed of my grandma . I know that’s a   21     thing to say, but it was true until today , so I have to     22   it .

The    23    started when my friend Katy found Grandma’s false teeth floating in a glass on the bathroom sink . I was so used to seeing them that I    24    took notice of them . But Katy shouted , laughing and    25    to talk to them . I had to get down on my knees and    26    her to shut up so my grandma wouldn’t    27    and get hurt .

After that happened , I   28     there were a million things about Grandma that were embarrassing .

Once she took Jill and me out to Burger King .  29     ordering our hamburgers well-done , she told the person behind the counter , “They’ll have two Whoppers (巨无霸) well-to-do.” Jill burst out laughing , but I almost    30    .

After a while , I started wishing I could    31    Grandma in a closet . I even complained to my parents . Both my parents said I had to be careful not to make Grandma feel    32    in our home .

Then last Wednesday, something happened that    33    everything completely . My teacher told us to help find interesting old people and   34     them about their    35    for a big Oral History project . I was trying to think of someone when Angie pushed me gently .

“Volunteer your grandmother ,” she whispered . “She’s    36    and rich in experience.”

That was the last thing I ever thought Angie would say about my grandma .

This is how I ended up on    37    today interviewing my own grandmother before the whole school assembly . All my friends and teachers were listening to her    38    she was a great heroine . I was   39     of my grandma and hoped she would    40    know that I had been ashamed of her .
