those students would never forget.
     He pulled out a wide jar (罐子) and put it on the table. He also took out several rocks and carefully put them
into the jar one at a time. When no more rocks would   2   inside, he asked, "Is this jar full?"
     Everyone in the class shouted, "Yes." The teacher replied, "Really?" He pulled out a box of small stones. He
dumped some in and   3   the jar. The stones went down into the spaces   4   the big rocks. He then asked the
group once more, "Is this jar full?"
     "Probably not," one of them answered. "Good!" he replied. He brought out a glass of sand and dumped the
sand into the jar and it went into all of the spaces   5 . Once more he asked the question,"Is this jar full?"
     "No!" the class started. Once again he said, "Good!" Then he poured a cup of water in   6   the jar was full.
