     An apple a day keeps a doctor away. Have you ever heard anyone say this? Do you think if people eat

one or two apples a day they won't get sick? 

     Last year some scientists wanted to find out if this old saying is true. They divided a college class into

two groups. The first group ate 2 apples a day. The second group didn't eat apples. After six months they

added up the times the young people got sick. The apple eaters turned out to be healthier than those who

hadn't eaten apples. It seemed to show that an apple a day does keep people healthy.

根据短文内容，判断正（T）误（F）。

( )1. An apple a day can make you strong enough to drive a strong doctor away.

( )2. If people eat an apple a day without eating other food they won't get sick at all.

( )3. Scientists found out that the old saying is true.

(     )4. The second group was not as healthy as the first group.

( )5. Nowadays the old saying doesn't work any more.
