英語翻譯
A science teacher wants to show some idea to his students.He takes a large-mouth bottle and places several large stones in it.He then asks the class,"Is the bottle full now?" They all reply,"Yes!"
The teacher then takes some small rocks and puts them into the bottle .The small rocks go into the spaces between the big rocks.He then asks,"Is it full?" This time some students give no answer,but most reply,"Yes!"
The teacher then starts to drop some sand into the bottle.The sand fills up the spaces between the small rocks.For the third time,the teacher asks,"Is it full?" Now most are doubting,but still,some reply,"Yes!"
Then the teacher brings out a cup of water into the bottle."What's the point of this show?" asks the teacher.One bright student answers,"No matter how busy you are,you can always find time to do some more things."
"No,"says the teacher,"the point is that if you don't place the big rocks first,you'll neverget them in.The big rocks are the important things in your life.If you fill your life with small things--as shown by the small rocks,the sand and the water - you'll never have the time for the important things."

解答：

一位自然老師想告訴他的學生一些道理.他拿了一個大口瓶,向裡面放了一些大石頭,然後問全班：「瓶子滿了嗎?」所有人都回答：「滿了!」
老師又拿了一些小石頭放進去.小石頭填塞了大石頭的空隙.他又問：「滿了嗎?」這次有一些同學沒有回答,但是大部分都回答：「滿了!」
老師又開始向裡面倒沙子,沙子填補了小石頭間的空隙.第三次,老師問：「滿了嗎?」大部分人開始懷疑了,仍然,有一些回答：「滿了.」
然後老師又拿了一杯水倒進了瓶子.「有誰知道,通過這次的展示我想向你們說明什麼?」老師問.一個聰明的學生回答：「不論你多麼繁忙,你總是可以找到時間去做更多的事情.」
「不,」老師說道,「關鍵在於,如果你不先放大石頭,這些東西是不可能全部放進去的.大石頭是你生活中最重要的東西.如果你讓如實驗中的小石頭、沙子和水一樣瑣碎的事情充滿了你的生活,你永遠沒有時間去做重要的事.」
