Once upon a time a king, in the company of his ministers, went to the imperial garden for a walk. When he was walking around a pond, a strange idea 26 upon him and he asked, “How many buckets(桶) of water are there in the pond?” The ministers looked at each other, 27 to give an answer. Rather 28 , the king ordered, “You have three days’ grace. Any one who offers an answer will be handsomely awarded. Those who fail will be 29 .” The time limit was due in the twinkling（闪烁）of an eye, yet the ministers were still at their wit’s end. At this time a child appeared who declared that he knew the answer. The king told his 30 ministers to go with the child for the measurement. To their 31 , the child refused the suggestion with a smile, “It is very easy. No 32 to go to the pond.” This made the king laugh 33 ,  “Alright, let us know what it is.” The child winked (眨眼) and said, “That 34 on the size of the bucket. If it is as big as the pond, there is one bucket of water; if it is half as big, two buckets; if one third as big, three buckets; if...”“Stop! That’s it. You’ve got the 35 .” The king was satisfied and the child was duly rewarded. Why did the ministers feel it so different to settle the problem? Because they fell in a pitfall (陷阱), following a wrong way of thinking. People’s thinking often goes a habitual way — the beaten track of straightforwardness. 36 is a static (静态的) way presupposing every object definite and certain, i.e. the size of the pond and the bucket should be clearly 37 . If one of them is unknown, it will be difficult to do the measurement, let alone 38 . Why not change your mode of thought — from static to dynamic（动态的）, from concrete to 39 ? If you adopt an indirect way and try to find out the proportional relation between the pond and the bucket, you’ll get an answer — flexible yet 40 to solve the problem. Sometimes to get out of the difficulty one must change one’s way of thinking, or simply change one’s approach towards a problem. 小题1: A．fixed B．focused C．came D．looked 小题2: A．struggling B．thinking C．falling D．failing 小题3: A．disappointed B．excited C．pleased D．contented 小题4: A．killed B．punished C．blamed D．scolded 小题5: A．exciting B．amazing C．surprising D．trembling 小题6: A．doubt B．surprise C．envy D．delight 小题7: A．good B．use C．need D．wonder 小题8: A．wonderfully B．joyfully C．cheerfully D．doubtfully 小题9: A．decides B．depends C．calls D．looks 小题10: A．award B．reward C．answer D．number 小题11: A．This B．That C．It D．Such 小题12: A．marked B．measured C．signed D．known 小题13: A．another B．other C．one D．both 小题14: A．detailed B．easy C．simple D．abstract 小题15: A．acceptable B．available C．adequate D．proper
