要一个300～400字的英语故事,带翻译,我要写故事梗概.

One day,a teacher took his pupils to a chicken farm to pay a visit.When they came near the incubator,chick just got out of its egg shell.
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.
"It's wonderful to see a little thing come out from the egg shell,isn't it?" the teacher said.
“看见一个小生命从蛋壳里出来,岂不是很奇妙的吗?”老师说.
"Yes,sir." said one of the boys," but it would be more wonderful if we knew how a chick gets in to its eggs hell before hand."
“是的,老师.”一个男学生说,“可是,如果我们知道它是怎样事先钻进蛋壳里的那就更奇妙了.”
