People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a 31 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 32; they try to find a solution by trial and error. However, when all of these methods 33, the person with a problem has to start analyzing. There are six 34 in analyzing a problem.35, the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 36 that there is a problem with his bicycle.Next the person must 37 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 38 the parts that are wrong.Now the person must look for 39 that will make the problem clearer and lead to 40 solutions. For example, suppose Sam 41 that his bike does not work because there is something wrong with the brakes. 42, he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.After 43 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 44, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.In the end, one 45 seems to be the solution to the problem. Sometimes the 46 idea comes quite 47 because the thinker suddenly sees something in a 48 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 49 the brake.Finally the solution is 50. Sam does it and finds his bicycle works perfectly. In short he has solved the problem.31.

The insect behaves like a parasite—an organism that lives on or in another organism called a host. This exceptional fly places larvae—young flies onto a cricket (蟋蟀) host. The larvae dig into the cricket and eat the insect from the inside out.The tiny yellow fly lives in Central America and the Southern United States. It finds its host by listening out for the cricket’s high chirping voice. The fly can easily find a cricket from as far away as 91 meters.Neal Hall is a sound engineer who worked on the new hearing aid model. According to him, the fly’s behavior is very strange. Mr. Hall and his team at the University of Texas made a copy of the fly’s hearing structure. “They discovered that the fly has a clever mechanism and instead of using two independent ears like a human does, the fly’s ears are actually coupled,” said Hall.The fly’s ears are two millimeters apart. That distance is so small that sound reaches one ear just four millionths of a second before arriving at the other. Experts held that it should be impossible for the fly to identify where a sound is coming from. In fact, however, inside this fly’s each ear is a 1.5-millimeter-long structure similar to a see-saw —a piece of children’s playing equipment. Like the see-saw, the fly’s ea r structure goes up and down from a central point. Pressure waves against the structure increase the time it takes for sound to travel and permit the fly to find its host.Mr. Hall and his team used the chemical element silicon to copy the fly’s ear structure. They also used the special electric materials that enabled them to measure its movements at the same time. Hall said that the hearing aid device could be used in two ways. One way would be to help the military on the battlefield, where sensors could find where shots are coming from. The other would be to remove unwanted noise from a person’s surroundings.“It is a feature that is incredibly useful for hearing aids, for example, here and now, if you turn up the gain of a hearing aid or turn the volume up to hear someone across from you, it also amplifies (放大) everything else in the room,” said Hall.Hall said that the next test in marketing the hearing aid device was to make it usable. He said the device must be handled carefully because it is so small. He noted that the fly does not have this concern.55.
