第二节 短文理解1
阅读下面短文,从[A](Right)、[B](Wrong)、[C](Doesn't Say)三个判断中选择一个正确选项。
Fishing is my favourite sport. I often fish for hours without catching anything. But this does not worry me. Some fishermen are unlucky. Instead of (代替) catching fish, they catch old hoots (鞋子) and rubbish (垃圾). I am even less lucky. I never catch anything ... not even old hoots. After having spent whole mornings on the river, I always go home with an empty bag. "You must give up fishing!" my friends say. "It's a waste of time." But they don't realize (意识到) one important thing. I'm not really interested in fishing. I'm only interested in sitting in a boat doing nothing at all!
