状元坊全程突破导练测系列答案To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．
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．”

Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being very overweight or obese during childhood can lead to serious problems normally seen in adults, such as diabetes and high blood pressure. Poor diets and a lack of exercise are usually the causes. But would you ever have imagined there might be a connection between the bacteria that lived in your guts （内脏）when you were a baby and the chance that you would become overweight?
Scientists in Finland recently found just such a link. In a recent study, they showed that overweight kids had different species of bacteria living in their guts.
You probably think of bacteria only as germs that can make you sick. While it’s true that some bacteria can make people ill, your body actually depends on some types of bacteria to help you digest food and extract nutrients from it. These “good” bacteria live in your guts, where they process the food you eat.
Human babies get these bacterial helpers from their moms. When a baby is born, some of the bacteria in the mother move into the baby’s body. Growing babies get additional “good” bacteria from the milk their mothers produce. And it turns out the bacteria might play an important role in regulating weight just six years later.
So how could these bacteria affect weight? The researchers still haven’t tested that question, but future tests might lead to an answer.
【小题1】The “link” in Paragraph 2 refers to the relationship between _______.
| A．bacteria and the chance of being overweight | B．obesity and diabetes |
| C．diets and the chance of being overweight | D．bacteria and exercise |
| A．Helping to digest food. | B．Helping to take nutrients from food. |
| C．Helping to regulate weight. | D．Making a person ill. |
| A．introduce the role of bacteria in children’s weight |
| B．analyze the influence of obesity on kids |
| C．give advice on how to lose weight quickly |
| D．explain the function of bacteria in foods |
