Do you ever hear anyone say, "An apple a day keeps the doctor away." ? Do you think if people eat
apples they won't get sick?
Some scientists (科学家) wanted to find out if this old saying is true. They divided (分开)a college
class into two groups. The first group ate two apples a day. The second group did not eat any apple.
After a few months, they find that the apple eaters were healthier than the others. It seemed that an apple
or two apples a day really does keep the doctor away.
