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（偏/啊/一点更美味）. Exercise is important if you want to get in（可连读） good shape（应该shape重读，而不是good重读）. But experts （是e，不是i的音）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 （r似乎没有卷舌）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（weight应该重读）. Many of us gain weight（weight应该重读） because of inactivity（na可以连读） during the winter.
