题目列表(包括答案和解析)

People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinions or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error(反复试验).  38 , when all of these methods 39 , the person with a problem has to start analyzing. There are six 40 in analyzing a problem.

41 ,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 42 that there is a problem with the bicycle.

Next, the person must find out the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.

Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam decides that his bicycle does not work because there is something wrong with the brakes.  46 , he can look into his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.

After 47 the problem, the person should have 48 suggestions for a possible solution. Take Sam as an example 49 , his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.

In the end, one 50 seems to be the solution to the problem. Sometimes the

51 idea comes quite 52 because the thinker suddenly sees something new or sees something in a different way. Sam, for example, suddenly sees there is a piece of chewing gum (口香糖) stuck to a brake. He 53 hits on the solution to his problem: he must 54 the brake.

Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

Five thousand years ago, people thought that illnesses were the result of evil living in human bodies. They also believed that gods and superior spirits were punishing people through diseases. The practice of magic and witchcraft (巫术) was popular among many tribes, and charms (符咒) and images of gods to drive away the evil spirits were often used.
People also started using herbal(草药的) medicine and by trial and error (反复试验,不断摸索) learned how to cure stomachaches and fevers. They had a witch doctor in the community. He would treat people with simple herbal medicine and magic. Early medicine was practiced the way north tribal Indians did hundreds of years ago and the way some tribes practice it today.
The ancient Chinese believed that the body was ruled by two forces, which they called “yin” and “yang”. The body would become ill if one force overcame the other and the balance between them was changed. Acupuncture (针刺疗法) was the way to bring back the balance between the two.
Also sand painting was an important part of Navaho medicine. The medicine man paints loosely upon the floor of an earth-covered house, where the ceremony takes place, or on a buckskin (鹿皮) or a piece of cloth, by letting the colored sands flow through his fingers with control and skill.
Ancient Mesopotamians believed that diseases come either from an evil spirit or a physical problem, such as worms. The doctor would decide from which source the illness has come from and send the patient either to a herbalist or to a witch doctor.
Egyptians had a very advanced medicine. They would sometimes rely on the god’s power to receive healing, but they also treated illnesses and operated on minor health problems like snake bites. They sucked the blood from the wound and bound the affected limb to stop the poison from spreading.
66. The practice of magic and witchcraft was popular in ancient times because ________ .
A. people could avoid being punished by gods and superior spirits by doing this.
