　　Once I read about an expert on the subject of time management. One day this expert was speaking to a group of business students. He said, "Okay, time for a(n) 11 ." Then he pulled out one big and wide-mouthed jar (坛子) and set it on a table in front of him. Then he took out some big rocks and 12 and slowly placed them, one at a time, into the jar.

　　When the jar was filled to the top and no more 13 would fit inside, he asked, "Is this jar full?" Everyone in the class said, "Yes." Then he said, "Really?" He 14 under the table and pulled out some gravel(沙砾). Then he 15 some gravel in and shook the jar causing 16 of gravel to work themselves down into the spaces between the big rocks. Then he smiled and asked the group once more, "Is this jar full?"

　　By this time the class was silent. " 17 not," one of them answered in a low voice. "Good!" he replied. And he reached under the table and 18 out some sand. He started pouring the sand in and it went into all the spaces 19 between the rocks and the gravel. Once more he asked the question, "Is this jar full?'" No" the class shouted. Once again he said, "Good!" Then he caught a bottle of water and began pouring it in until the jar was filled to the top. Then he looked up at the class and asked, "What 20 can you reach from the experiment?”

　　One 21 his hand and said, "The point is, no matter how full your timetable is, if you try really hard, you can always 22 some more things into it!' "No," the expert replied, "that's not the point. The truth is: If you don't put the big rocks in first, you'll never get them in at all."
