Ⅲ.阅读理解

A

Looking almost as fresh as the day it was bought, this McDonald's Happy Meal is in fact six months old. Photo－graphed every day for the past six months by Manhattan artist Sally Davies, the kids meal of fries and burger hasn't any signs of mould(霉菌) or decay(腐烂)．

Sally put the Happy Meal on a shelf in her apartment and watched it with increasing shock. Even her dogs stopped trying to steal a free tasty snack.

“I bought the meal on April 10 this year and brought it home to see how it changed，” she said.“I chose McDonald's because it was nearest to my house，but the project could have been about any other fast food. The first thing that shocked me on the second day of the experiment was that it no longer gave out any smell. And my dogs stopped circling the shelf.”

Sally expected the food to go mouldy after a few days. In fact, Mrs. Davies' surprise turned to shock as the food still had not shown any signs of decay after two weeks. “It was then that I realized that something strange might be going on with this food that I had bought，” she explained. “The appearance of the food did not change as the weeks turned to months. And now, at six months old, the food is plastic to the touch. The only change that I can see is that it has become as hard as a rock.”

The experiment has brought her amusement rather than fear. “Maybe I would be frightened at seeing this if I were a meat eater，” she said.

Your weight has been important since the moment you were born. Maybe you even know what your birth weight was. Most newborns weigh between 6 and 9 pounds, but some may weigh more and some less. But very quickly, a baby gains weight and everyone is glad about that because it means the child is growing bigger and stronger.

As you get older, your weight is still important. It's something your parents and doctor will probably keep an eye on. When you go for a checkup, the doctor often

records your height and weight and compares it with what it was the last time you came in. The doctor wants to check whether you have a healthy weight because weighing too much or too little can be a problem.

But these days, being overweight is more common than being underweight. In the last 30 years, a growing number of kids and teenagers have developed weight problems. Today, 1 out of 3 kids and teens between the ages of 2 and 19 are overweight. Many grown－ups understand what it's like to have weight problems, since 2 out of every 3 adults are overweight.

For kids and adults, weighing too much can lead to illnesses and health problems. And a kid who is overweight might be made jokes on or find it hard to keep up with friends on the playground. When people talk about being overweight, they mean that someone has more body fat than a healthy one. Everyone has some body fat, but extra(多余的) fat can influence people's health and ability to walk, run, and get around, as well as how the person looks and his or her self－respect.
