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．

Many songs, poems, and books have been written on love’s strong effect on people. The state of being in love has even been compared to being sick or mad. A study by Professor Semir Zeki of University College London has found that love does affect people’s brains by making them feel great.
Zeki studied young men and women who had recently fallen in love. He found that, when they were looking at photos of their loved ones, there was heightened activity in four areas of their brains. These areas deal with emotions, and one of them, in particular, is known to respond to drugs that cause feelings of great joy and excitement.
Interestingly, the study also found a lack of activity in two other areas of the brain when the volunteers looked at their lovers’ photographs. One of these areas is linked to feelings of sadness, while the other is often active in people suffering from depression. It seems love really can be uplifting.
The state of being in love, according to some scientists, may actually be good for your health. Although scientists know that being in love can make a person feel great, the exact influence of love on a person’s health is harder to determine. However, scientists say that people do need love in order to live healthy lives.
According to Dr. Thomas Lewis, people need to be in relationships because that is how we are designed. He says the brain can only maintain(保持) the overall stability of a person’s immune(免疫) system, bodily rhythms, and heart if it receives input(输入) from outside the body in the form of emotional connections with others.
Professor Antonio Damasio has a similar view. He says that love enriches a person’s imagination and creativity, and makes a person’s body work better. He also believes that love can even improve the body’s ability to fight against disease. Damasio’s wise words of advice are “ Choose love and you will live longer.”The main idea of this passage is __________.

The second Frenchman said, “I was once in a ship and heard the captain shouted, ‘All hands on decks (甲板)’ I put my hands on the deck and someone walked on them.”
The third Frenchman said, “I once called early on an English friend and the maid (女佣) who came to the door said, ‘He’s not up yet’ When I went again for him, she said, ‘He’s not down yet’. I said, ‘If he’s not up and he’s not down, where is he?’ She said, ‘He’s still upstairs now.

According to the Ministry of Health, 260 million Chinese people have chronic（慢性）diseases, and 85 percent of all deaths in China are caused by such diseases．Among them, cardiovascular（心血管的）disease has bothered more people than any other kind of chronic disease．
According to the WHO（World Health Organization), salt consumption（消耗）, one of the key causes of high blood pressure that can lead to cardiovascular disease, is much higher in China than in other countries．
Douglas Bettcher, the director of the WHO’s Tobacco Free Initiative, says, “The average Chinese person consumes about 12 to 14 grams （of salt) per day, while the suggestion of the WHO is consumption of less than 5 grams per day．High salt consumption is a major cause of cardiovascular disease and high pressure in China．
Changing the way that food is prepared could reduce salt consumption in China．
Another major risk factor in China is smoking．Dr Michael O’Leary, a representative of the WHO, says, “We know already that one million deaths in China are related to smoking, This is an enormous number．It means that we are seeing nearly 3000 deaths a day in China, or two deaths every minute, related to smoking．
According to O’Leary, about 26 percent of men who die from smoking-related diseases in China die before the age of 60．People who can still contribute a great deal, in other words, are dying too young．
China has tried to ban smoking , but more efforts are needed．
More than half of chronic diseases are preventable by changing lifestyles and reducing risks．The four key risk factors are: smoking, diets high in fats, salt and sugar, environments that prevent physical activities, and alcohol consumption．These are the areas on which efforts to make changes need to concentrate．Which of the following is more in China than in other countries?

| B．The number of deaths caused by high blood pressure． |

| B．Less than 5 grams per day． |
| C．About 17 to 19 grams per day． |
| D．About 7 to 9 grams per day． |

| B．To show smoking causes the deaths of elderly people． |
