题文

Health experts have long worried about the increasing rate of obesity in kids. It’s an important concern: Being very overweight or obe during childhood can lead to rious problems normally en in adults, such as diabetes and high blood pressure. Poor diets and a lack of exerci are usually the caus. 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. The “good” bacteria live in your guts, where they process the food you eat.Human babies get the 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 the bacteria affect weight? The rearchers 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 overweightB．obesity and diabetesC．diets and the chance of being overweightD．bacteria and exerci小题2:Which of the following is NOT the function of “good” bacteria?
