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，老師帶學(xué)生到養(yǎng)雞場參觀，當(dāng)他們走近孵化器時(shí)，剛好一只小雞破殼而出。
"It's wonderful to see a little thing come out from the egg shell, isn't it？" the teacher said.
“看見一個(gè)小生命從蛋殼里出來，豈不是很奇妙的嗎？”老師說。
"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，老師。”一個(gè)男學(xué)生說，“可是，如果我們知道它是怎樣事先鉆進(jìn)蛋殼里的那就更奇妙了。”
