跟美风，读VOA,请给砖。谢谢

This is SCIENCE IN THE NEWS in VOA Special English. I’m Shirley Griffith.

And I’m Bob Doughty. Today, we will talk about diet and weight loss. Exercise is important if you want to get in good shape. But experts say exercise alone is not enough if your goal is to lose weight.

It is that time of year again! Warm weather has returned to Earth’s northern hemisphere. Summer is a time when people of all ages feel like getting their swimwear and going to the nearest swimming pool or seashore. But first, there is that troublesome little thing called winter weight gain. Many of us gain weight because of inactivity during the winter.
