一天，老師帶學(xué)生到養(yǎng)雞場(chǎng)參觀，當(dāng)他們走近孵化器時(shí)，剛好一只小雞破殼而出。

“看見(jiàn)一個(gè)小生命從蛋殼里出來(lái)，豈不是很奇妙的嗎？”老師說(shuō)。

“是的，老師。”一個(gè)男學(xué)生說(shuō)，“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。

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.

“Its wonderful to see a little thing come out from the egg shell， isnt it？” the teacher said.

“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.”
