参观养鸡场

　One day,a teacher took his pupils to a chicken farm to pay a visit. When they came near the incubator, a chick just got out of its eggshell.
　　It's wonderful to see a little thing come out from the eggshell, isn't it ?" The teacher said.
　　"Yes, sir, "said one of the boys,"But it would be more wonderful if we knew how a chick gets into its eggshell beforehand."

　　一天，老师带学生到养鸡场参观，当他们走近孵化器时，刚好一只小鸡破壳而出。
　　“看见一个小生命从蛋壳里出来很奇妙，是不是？”老师说。
　　“是的，老师，”一个男学生说，“可是，如果我们知道它事先是怎么钻进蛋壳里的，那就更奇妙了。”
