After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn"t．
“We"ve known for a long time that these behaviors are good things to do, but we"ve not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain"s Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”
Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
“We can"t say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what"s theoretically（理论上地）possible．”
“Most people
know that things like a good diet matter and that smoking isn"t good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”小题1:Which of the following DOESN"T belong to the four healthy habits?
| A．Eat five servings of fruits and vegetables a day． |
| B．Do proper exercise in the morning every day． |
| C．Drinking alcohol in the proper amount every day． |
| D．Having a cigarette before going to bed every day． |
| A．Susan Jebb did not take part in the study． |
| B．the study observed people as well as tested specific changes． |
| C．there"s no need for people under 45 to adopt these good habits． |
| D．only those from first class can benefit from these healthy behaviors． |
| A．All the people are well aware of the harm of their bad habits． |
| B．People aged 45 to 70 have bad habits in the United Kingdom． |
| C．Governments should take measures to help people change their bad habits． |
| D．People have adopted the four healthy habits after knowing they"re good． |
| A．Smoking and Drinking Cuts You 14 Years |

But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria（细菌）to make you sick.
Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.
One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.
But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna（一种大红肠）on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.
So, forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. And this time, be careful not to drop it!
小题1:In which part of a newspaper can you most probably find this passage?
| A．Culture | B．Health | C．Advertisement | D．Technology |
| A．throw away dirty toast immediately and go away |
| B．pick up the toast as quickly as possible and eat it |
| C．eat the toast within 5 seconds and feel pleased |
D．get another piece of clean toast quickly and eat it |
| A．see how quickly bacteria can pollute food |
| B．show that the 5-second rule is correct |
| C．see how harmful bacteria are to people’s health |
| D．show that bacteria grow at different speeds on different foods |

A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister(滑润的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．

s stress or anxiety is often the mistake most people will make.Oh, poor digestion can lead to weight problems. Here’s how: When a person feels stressed, the part of the central nervous system that connects digestion switches off. This is called the parasympathetic nervous system(副交感神经系统). At those times of stress, the body can take in food and process some of it, but digestion doesn’t work correctly to digest all the nutritional(营养的)goodness from the food. Poor digestion is not always obvious by observing symptoms; you can get some illnesses but not always. Poor digestion can be seemingly silent.
If you eat when you are stressed, anxious, or nervous, you might as well be eating cardboard for all the nutrients your body gets. Yes, eating when stressed is a gaining situation. Now you might think, well, if I’m not digesting, the calories aren’t getting handles, so I should be losing weight. Good idea, but wrong reality. When digestion is not proper, the body starts “starving” from lack of necessary nutrients(营养物). Yes, it goes into a starvation（饥饿）problem and starts absorbing(吸收) fat and energy. It thinks it’s in a famine(饥荒). The good news is that it’s easy to make some corrections and get rid of stress at mealtimes.
If you feel stressed often, it can be helpful to take other food that contains multiple B vitamins. These help, but you could still find yourself stressed at mealtimes.

hy 49 years old and have come to the conclusion that it’s now or never, so I a
m taking a dive into the raw eating lifestyle.I have to cook for my family and
prepare what they want to eat. I’m trying to plan out this better so I have some of these unusual foods ready for myself.I’ve read several books written by Ann Wigmore and like her appr
oach to the living foods.Last week I atte
mpted fasting（禁食）and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn’t sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family.This week I started to make a drink called rejuvelac made of sprouted wheat（芽麦）. This is fairly new to do for me and the drink smelled sort of musty（发霉的）and tasted kind of like a musty lemon. The kids tasted it and almost t
hrew up but surprisingly it tasted good to me. It is supposed to help in digestion（消化）.I’ve made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I’m very frustrated(受挫的) with the
smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress.小题1:The author must have ________ before she wrote this article.
