15.Good health is the most valuable wealth a person can have,but one can't take good health for granted.It is important to remember that the body needs proper care in order to be healthy.There are three things that a person can do to help stay in good shape:eat the right foods,get enough sleep and exercise regularly.
Proper nutrition is important for good health.Your body cannot function well unless it receives the proper kind of"fuel".Avoid foods with lots of sugar and fat.Eat plenty of foods high in protein,like meat,fish,beans and nuts.Vegetables and fruit are especially important because they provide necessary vitamins and minerals.However,don't overeat.It is not healthful to be overweight.
Getting the proper amount of sleep is also important.If you don't get enough sleep,you feel tired and irritable(易怒的).You have no energy.Over a long period of time a little amount of sleep may even result in a change of personality.Be sure to allow yourself from seven to nine hours of sleep each night.If you do,your body will feel strong and refreshed,and your mind will be sharp.
Finally,get plenty of exercise.Exercise firms the body,strengthens the muscles and prevents you from gaining weight.It also improves exercise program,and you will probably increase your lifespan(壽命).Any kind of exercise is good.Most sports are excellent for keeping the body in good shape.Basketball,swimming,bicycling,gymnastics and running are all good examples.Sports are not only good for your body,but they are enjoyable and interesting,too.
If everybody were to eat the right foods and get plenty of sleep and exercise regularly,the world would be a happier and healthier place.We would all live to be much older and wiser.

20.Six years ago,a Miami woman walking through the hall of an office building casually noticed two men standing together.Several minutes after her leaving,the men murdered a person working in the building.Police investigators determined that the woman was the only witness who had seen the two suspects,and could possibly describe them.In an interview with police,her memory of the men proved disappointingly unclear.
Several days later,psychologist Ronald P.Fisher was brought in to get a more complete description from the woman.Fisher's interview produced a breakthrough (突破)-the woman reported a clear picture of one of the suspects.She then recalled several details about his appearances.This information gave police important leads that enabled them to arrest the suspects and close the case.
Police investigators found the help from Fisher because of his rich knowledge in conducting the so-called cognitive (認知的) interview,a kind of memory-rebuilding process.In its original form,the cognitive interview focuses on guiding witnesses through four general recalling techniques:thinking about physical surroundings and personal feelings that existed at the time of past events,reporting everything that comes to mind about those events no matter how broken or unconnected,retelling events in kinds of time orders,beginning to end,end to beginning,forward or backward,and accepting different views while recalling events.
Usually,an interviewer begins the cognitive approach by encouraging the witness to take an active role in recalling information rather than giving answers only to someone else's questions.The witness first describes what happened in his or her own words,with no interviewer interruptions.The interviewer then goes further with specific techniques,such as having the witness tell the details of what happened from different aspects.
Experiments with police detectives trained in this demanding interview method find that they get nearly 50% more information from witnesses than before training,while error rates remain about the same.
67.What is the purpose of this passage?D
A.To give an description of a murder case in an office.
B.To explain why Fisher was invited to a police interview.
C.To describe how cognitive method helps the woman to recall.
D.To give the readers an idea of cognitive interview.
68.The cognitive interview helped the woman to recall more byC.
A.strengthening her memory           
B.giving her encouragement
C.rebuilding her memory              
D.giving her more time
69.It can be inferred from the passage that in a cognitive interview,the interviewer mainly plays aArole.
A.directing         
B.questioning   
C.disappointing      
D.interrupting
70.What is the key point of the cognitive interview?B
A.The interviewer should interrupt the witness from time to time.
B.The witness is encouraged to take an active role in recalling information.
C.The interview should take place outside the police station.
D.The witness should recall details at the scene of the event.
