A geography teacher hung a map of the world’s river distribution(分布) in front of the blackboard. He 41 , “My dear classmates, what 42 does the world’s river distribution have?” “All of them are not straight lines, but bent curved(弯的) lines,” his students replied together. The teacher 43 to ask, “Why are these rivers not in the shape of straight lines but so many curves?” The students began to 44 the question and expressed their different ideas. Some said that the bends(弯道) of rivers 45 the flowing length. When the flood came in summer, these bends would 46 more water. Thus people would not suffer terrible flood disaster. Others said that once the flowing length increased, the impact force on the river bed would greatly decreased and the length played an important role in 47 of river beds.
After hearing what the students had discussed, the teacher made a 48 comment on the answers. He said to his students, “I am satisfied 49 your answers. What you have answered just now are all correct.” The teacher continued to 50 , “In my opinion, the reason why the rivers are in the shape of bends not in straight lines is that bends are natural states while straight lines are 51 states. When rivers run and extend far away, they will meet various obstacles, some of 52 are not possible to be got rid of. Therefore rivers have to 53 their ways, thus making many bends on way forward. The bends help rivers avoid numerous 54 . This makes rivers finally reach the far-away sea.” At this time, the teacher 55 his topic. He continued to say, “ In reality, life is also like this. When you encounter troubles, 56 , or sufferings, you should consider them a natural state in hard life. You should not be 57 or pessimistic. We should not stop going 58 . We should take bends as another normal form of advancement in journey of life. Only in this way can you reach the far-away sea of life like winding rivers.”
We should remember the 59 that a long and winding road is a natural state. We should treat troubles and sufferings in good and tolerant state of mind. This is the life 60 I have gotten from the geography teacher’s lesson.
