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．

A. Because people think they are much healthier.
B. Because they are more delicious.
C. Because people prefer organic food.

Upon entering college, Yang Yi was uncertain about a lot of things. However, the 19-year-old international economics and trade student was certain about one thing: She wanted to participate in animal welfare efforts.
“I'm .always a nature and animal lover," she said. She joined the environmental protection association at her school. Now being president of a group of 25, she leads its efforts to help stray（流浪）cats and dogs by raising money to buy them food and collecting old clothes to make them homes.
However, sometimes the association raises doubts. Some students have questioned whether helping stray animals breaks the laws of nature. "We tried to resolve the controversy," Yang said. “For wild animals, the best way to protect them is to preserve their environment and their natural habitat, and to let them live their own way. However, for animals that depend heavily on humans, such as dogs and cats, the proper way to treat them is to respect them and take care of them." Besides, if not accommodated properly, stray animals can bring threats to public health, as they are the main cause of rabies（狂犬病）in cities. "Now, many young people in China have agreed upon the need to strike a balance between humans and nature. The only problem is how," said Yang. Yang and her fellow volunteers are cautious about what they do to help. For instance, sometimes people feed stray cats human food such as chocolate. But Yang and her friends point that such food can be dangerous to stray cats.
Yang also cooperates with Non-Governmental Organizations to spread animal protection knowledge. One of their recent exhibits was about animals in the entertainment industry. "We are still figuring out the best way to protect animals, but simple deeds such as saying no to animal performances can prevent wildlife from being captured and tamed. Step by step, we'll eventually reach our goal," she said.Why did Yang Yi join the environmental protection association?

According to researchers, money can buy happiness, but only if you spend it on someone else．
Spending as little as $5 a day on someone else could significantly bring you happiness, the team at the University of British Columbia and Harvard Business School found.
Their experiments on more than 630 Americans showed they were measurably（适度地） happier when they spent money on others---even if they thought spending the money on themselves would make them happier.
"We wanted to test our theory that how people spend their money is at least as important as how much money they earn," said Elizabeth Dunn, a psychologist at the University of British Columbia.
They asked their 600 volunteers first to rate their general happiness, report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity（慈善机构）．
"Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not," Dunn said in a statement.
Dunn's team also surveyed（调查）16 employees at a company in Boston before and after they received an annual profit-sharing bonus（奖金） of between $3,000 and $8,000.
"Employees who devoted more of their bonus to pro-social（有益社会的） spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor(预示) of their happiness than the size of the bonus itself," they wrote in their report, published in the journal Science.
They gave their volunteers $5 or $20 and half got clear instructions on how to spend it．Those who spent the money on someone or something else reported feeling happier about it.
"These findings suggest that very minor alterations（改动） in spending allocations（分配） --- as little as $5 --- may be enough to produce real gains in happiness on a given day," Dunn said. According to the passage,_____________.
| A．the more money you spend on others, the happier you are |

At first glance, there is little in Horton to attract people. The other nearby towns have much more to offer: Bradfield has its river and historic buildings, while Newtown has shops and entertainment. The buildings of Horton look dirty and unloved. For shops, there is a small supermarket, a few bargain shops, a bakery which, strangely, does not sell bread and a florist which has one stand of sad-looking flowers. Even so, Horton has several advantages over its neighbouring towns.
Firstly, it has a country park. Four thousand years ago, this was an important fort. There are no historic remains here now, but there are wonderful views over the countryside. On sunny weekends you can often see kids out with their parents, kicking balls or flying kites.
There aren’t many job opportunities in Horton, and the roads to nearby cities aren’t really fast, but there are excellent rail links. You can be in London in an hour and a half, and other cities are less than an hour away. That means that parents can earn a good salary and still get home in time to spend the evenings with their families. Houses in Horton aren’t pretty, but they’re functional and cheap.

After having worked in the University of Maryland for three years, I got a job offer from another university---Lynn University. I left my letter of offer on my present boss's desk, turned around, and closed the door quietly. I was expecting a call from my boss saying congratulations, which would show her approval of my leaving.
In the afternoon, my boss called me, saying, "Can we meet tomorrow? "That was a good signal. The next day, I met with my boss. She said, 'Nicholas, we want you. What do you want?" I said, "Boss, I deserve a significant pay raise this year due to my outstanding performance. I think I need a 10% pay raise next year as a condition for me to stay here." My boss said, "No problem.''
When I left her office, I called Lynn University and told them that I was going to get a 10% pay raise. They had to give me 10% more than their original pay offer in order for me to accept the job. The new boss told me that he was willing to give me more, but I would feel very bad working at this university with such a high pay. I would win a battle, but I would lose a war. He said, "The problem is that your colleague will earn less than you, so you will feel guilty(内疚)and uncomfortable. But, I can still give you 5% more than the original offer."
I delivered this massage to my present boss, and she told me that she would give me another 5% pay raise if I promised to refuse this new job offer. On top of that, she would strongly support my early promotion（晋升)from assistant professor to associate professor. According to the university policy, you must take at least 6 years to get promoted. That was my third year of employment at this university.

Have you ever heard the saying “All roads lead to Rome”? At one time, this was pretty much true. During the Roman Empire, lots of roads were built in order to move armies, send messages by courier (信使), and make trade easier.
The network of Roman roads was begun in 312 BC. It was demanded that the roads be built strong so that they would not fall down. Roman soldiers, supervised (监督) by engineers, laid down the roads in a special pattern of layers. There were all together 4 layers, which was made of different materials, such as sand, rocks, stones and so on.
Also, Roman roads were cambered(拱形). This means that they were built higher in the middle than on the edges, allowing rainwater to run off, which prevented flooding. We use the same technique in building roads today. The Romans also laid out roads over hills when necessary, setting them down in a zigzag (之字形的)pattern to make the road rise gradually.
All Roman roads had milestones (里程碑), placed every thousand paces (a Roman mile). The milestones told when the road was built, who was emperor at the time, the road’s destination, how far the traveler was from the destination, and how many miles had been traveled since the beginning of the road. This information was a great help to travelers.
Because of their excellence in construction, it really is no surprise that many parts of Roman road still exist today. These roadways are one of the most impressive achievements of the Roman Empire.The following description about Roman roads is true EXCEPT _____.
| A．Roman roads were built by the Roman soldiers directed by the engineers |
| B．Roman roads could prevent flooding using the technique we don’t use today |
| C．Roman roads had milestones that were placed every Roman mile |
| D．Roman roads still exist today as an impressive achievement of Roman Empire |
What information can you find on the milestones?
