Passage Two
Researchers have discovered a link between drinking and thinking. A moderate amount of alcohol may help us keep our mental abilities as we age. Brain scans show alcohol abuse kills brain cells. But little is known about the effects of life-long drinking. So moderate drinkers may want to toast new findings from researchers at Duke, Indiana Universities. Dr. Joe Christian of Indiana Universities says men who have one or two drinks each day retain slightly stronger comprehension skills than the nondrinker or the heavy drinker. The doctor and his colleagues gave mental tests to nearly 4,000 male twins between the ages of 66 and 76. The moderate drinkers had slightly better reasoning ability than their brothers who drink more or less. Other studies have found that alcohol in moderation can help the heart. But alcohol abuse can cause bone loss and other health problems. This study was presented at an alcoholism meeting in San Antonio。

Passage Three
Our family is trying to decide where to go for a vacation this summer. Our son Tom wants to go to Yellow Stone Park again to see the bears. We did that last summer and what an experience it was! When we got there, we put up our tent and went to explore. As we returned, we heard our daughter Susie cry out and then we saw a bear enter our camp. Tom wanted his father to chase him away. His father said, “No, it’s dangerous to chase a bear. And don’t let him chase you。” Susie said: “What shall we do?” “Maybe we ought to climb a tree。” Tom said: “No, weve got to get him out of there. He might go to sleep in our tent。” “Maybe we could make him leave if we put some honey outside for him to eat。” Susie suggested. Then I said: “How are you going to get the honey? It’s in the tent。” We watched the bear enter the tent and heard him upset everything inside. “It’s foolish for us to try to catch him,” said my husband. “Leave him alone and wait for him to come out。” We waited but the bear stayed inside. We had to sleep in the car。
