Organic food has no nutritional or health benefits over ordinary food，according to a major study．
Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its imagined health benefits，creating a global organic market worth an estimated $48 billion in 2007．
A systematic review of 162 scientific papers published in the scientific literature over the last 50 years，however，found there was no significant difference．
“A small number of differences in nutrient content were found to exist between organically and conventionally(通常)produced foodstuffs，but these have nothing to do with public health，” said Alan Dangour ，one of the report's authors．
“Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority ．”
The results of research，which was commissioned by the British government’s Food Standards Agency，were published in the American Journal of Clinical Nutrition．
Sales of organic food have fallen in some markets，including Britain，as a slowdown in economic growth has led consumers to cut back on purchases．
The Soil Association said that growth in sales of organic products in Britain slowed to just 1.7percent，well below the average annual growth rate of 26 percent over the last decade．
64. Why does organic food cost more than conventionally produced food?
A. Because people think they are much healthier.
B. Because they are more delicious.
C. Because people prefer organic food.
D. Because they sell better.

Today's Britain is full of TV shows like Fame Academy, which claim to offer young hopefuls an instant passport to fame and riches. But a very different kind of academy may provide a new generation of Brits with a slower, steadier path to wealth.

A 'pig academy' in the east of England is aiming to train up new pig farmers to help promote local agriculture and meet the UK's growing demand for pork. Last year consumption of pork products increased by 6,000 tonnes. But British farmers have not benefited from this rise in demand. A combination of increasing feed prices, competition from cheaper imports and an outbreak of foot and mouth disease have all eaten into their profits. Pig numbers in the UK have actually almost halved in the last decade.

Now, Fresh Start Pig Academy in Lincolnshire is launching a course which intends to redress (修复) the balance. They say pig husbandry (养猪业) is a growth industry and newcomers are welcome. For those of you who fancy getting your hands dirty, the course will teach you everything you need to know, from keeping pigs healthy to raising the capital needed to start up.

Pig farmer Anne Longthorp followed her father into the industry and believes that farming pigs is very rewarding work: "They're great, curious animals to work with. Just watching their behaviour – it's really interesting work. There is a lot more to pig farming than people give us credit for. It's very scientific."

So, while most of Britain's young people may continue to dream of overnight stardom, others will hope a more traditional career will help them bring home the bacon.

A. why              B. how            C. when           D. where

2.Which is not the contribution to the decrease in pig farmers' enthusiasm? 

A. growing demand for pork                 

B. increasing feed prices

C. competition from cheaper imports

D. outbreak of foot and mouth disease

3.From the passage we can infer that the Pig Academy will         .  

A. lead the youth to riches faster than the Fame Academy

B. provide geilivable help for whoever attends the course

C. be more popular with young people than other academies

D. make some young people overnight star

4. What does the underlined phrase "getting your hands dirty" probably mean?  

A. making your hands dirty by raising pigs         

B. taking up the job as a pig farmer

C. avoiding the pig bed dirty to keep them fit             

D. collecting enough money to raise pigs

5.Which of the following statements is true according to the passage?  

A. Anne Longthorp loves the job of farming pigs.

B. Anne Longthorp’s family all like raising pigs.[来源:Z*xx*k.Com]

C. Most young people in Britain will like the career of farming pigs.

D. People who farm pigs are allowed to bring home many bacons.

The word “conservation” has a thrifty meaning. To conserve is to save and protect, to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment. Our forefathers had no idea that human population would increase faster than the supplies of raw materials: most of them, even until very recently, had the foolish idea that the treasures were “limitless” and could “last forever”. Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature, and which means that, as in a living body, an unhealthy condition of one part will sooner or later be harmful to all the others.

　　Fifty years ago, nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word “conservation” had nothing of the meaning that it has for us today.

　　For the sake of ourselves and those who will come after us, we must now set about correcting the mistakes of our forefathers. Conservation should be made part of everybody’s daily life. To know about the water table in ground is just as important to us as a knowledge of the basic math formulas. We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea. We need to be taught the duty of planting trees as well as of cutting them. We need to know the importance of big, grown trees, because living space for most of man’s fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth. In a word, it should be our goal to restore as much of the original beauty of nature as we can.

1.The author’s attitude towards the use of natural resources is _________.

A. positive         B. uninterested     C. optimistic           D. critical

2.According to the author, the greatest mistake of our forefathers was that _________.

　　A. they had no idea about scientific forestry

　　B. they had little or no sense of environmental protection

　　C. they were not aware of the importance of nature study

　　D. they had no idea of how to make good use of raw materials

3.To avoid repeating the mistakes of our forefathers, the author suggests that ______

　　A. we plant more trees

　　B. natural sciences be taught to everybody

　　C. environmental education be directed toward everyone

　　D. we return to nature

4.How can you understand the underlined sentence in the last paragraph?

A. Our living space on the earth is getting smaller and smaller.

B. Our living space should be measured in cubic volume.[来源:Z。xx。k.Com]

C. We need to take some measures to protect space.

D. We must preserve good living conditions for both birds and animals.

There is an endless supply of stories about sleepwalkers (梦游者). People have been said to climb on roofs, solve mathematical problems, write music, walk through windows, and do murder in their sleep.

       In Revere, Massachusetts, a hundred policemen searched for a lost boy who left his home in his sleep and woke up five hours later on a strange sofa in a strange living room, with no idea how he had got there.

       At the University of Lowa, WWW.K**S*858$$U.COMa student was reported to have the habit of getting up in the middle of the night and walking three-quarters of a mile to the Lowa River. He would take a swim and then go back to his room to bed.

       An American expert on sleep claims (声称) that he has never seen a sleepwalker. He is said to know more about sleep than any other living man, and during the last thirty-five years he has lost a lot of sleep watching people sleep. He says, “Of course, I know that there are sleepwalkers because I have read about them in the newspapers. But none of my sleepers ever walked, and if I were to advertise for sleepwalkers for an experiment, I doubt whether I would get many takers (应征者).”

       Sleepwalking, however, is a scientific reality. It is one of those strange things that sometimes look quite fantastic (怪诞的). Doctors say that sleepwalking is much more common than is generally supposed. Many sleepwalkers do not try to find help and their sleepwalking is never recorded.
