Question

  Most students have biology classes in the classrooms or the labs in China. But several days ago,I had a biology class outside in my American school.

   My biology teacher,Mr. Kwak,divided us into three groups and asked us to play a game about natural selection (选择) and how birds find food.

   He gave the first group one spoon per person,the second group forks and my group knives. I thought we were going hunting,so knives might work better. Surprisingly,he told us to pick up the beans on the grass with our tools.

   When the game started,all of us ran to the grass area. We squatted (蹲) down and looked for beans. It was hard to pick up something that small,especially from the grass.

   When I almost lifted a bean,it dropped back to the ground. When I finally picked up several beans,one of my friends ran into me. I couldn’t keep my balance and fell over. All my beans dropped to the ground!Just at that moment,Mr. Kwak called us back. I had to leave the game and of course I got a bad result. I couldn’t help thinking that if I were a bird living on the Galapagos Islands,I would be dead soon.

   The fun game made me realize that natural selection is really competitive (竞争的) . Everyone is trying his or her best to survive.
