14.Most people will experience at least one wrong medical diagnosis in their lifetime,resulting in health problems,psychological suffering and financial cost,according to a new report.Because diagnostic errors are generally discovered in retrospect (回顾),researchers said more work needs to be done to improve medical teams and find ways to avoid errors that can change people's life in the distant future.
"Diagnosis is a collective effort that often involves a team of health care professionals----from primary care physicians to nurses,''said John Ball,chair of the committee which wrote the report."The type of a single physician observing a patient case and deciding a diagnosis is not always accurate,and a diagnostic error is not always due to human errors.Therefore,to make it possible to reduce diagnostic errors,we have to look more broadly at the entire process of how a diagnosis is made."
   The researchers said there are not enough data on diagnostic errors,and efforts to improve diagnosis and reduce errors have not been frequent.The medical culture discourages transparency and makes it more difficult to correct them.The blame lies in cooperation and communication between members of medical teams treating patients,patients themselves,and their families.Besides this,researchers found the healthcare system is not designed for the collaboration needed in the diagnostic process and that diagnosis will continue to worsen if new ideas are not put forward.
    The committee recommended more information,from electronic health records to test results,be made more easily available to families and caregivers,to help them better learn and understand what is going on with their health.Creating an environment for patients to question a diagnosis or add information about their condition could also help better influence diagnosis.
    Most significantly,the researchers said methods need to be established to make communication between doctors and patients easier.Doctors currently are not encouraged or paid to communicate with patients as much as they should be.

46.It can be inferred from the new report thatA
A.diagnostic errors have a great influence on people
B.new ways are found to avoid diagnostic errors
C.nobody can avoid those diagnostic errors
D.diagnostic errors are difficult to be found
47.Why does the medical culture make the correction of diagnostic errors so difficult?D
A.For lack of advanced technological equipment.
B.For lack of strict rules of managing the medical environment.
C.For lack of enough professional knowledge about medicinal treatment.
D.For lack of cooperation and communication between physicians,patients and their families.
48.What does Para.4 mainly talk about?C
A.Researches on the diagnostic process
B.New ways to better protect patients
C.Advice on reducing diagnostic errors
D.Communication between patients and doctors
49.Why is communication between doctors and patients not much?B
A.Because of the different belief
B.Because of the medical situation
C.Because of being short of money
D.Because of the current rules
50.The passage most probably comes fromB.
A.a hospital advertisement                     
B.a medical magazine
C.a science book
D.a research report.

4.Blind imitation (模仿)is self-destruction.To those who do not recognize their unique worth,imitation appears attractive;to those who know their strength,imitation is unacceptable.
    In the early stages of skill or character development,imitation is helpful.When I first learned to cook,I used recipes(菜谱)and turned out some tasty dishes.But soon I grew bored.Why follow someone else's way of cooking when I could create my own?Imitating role models is like using training wheels on a child's bicycle;they help you get going,but once you find your own balance,you fly faster and farther without relying on them.
    In daily life,imitation can hurt us if we subconsciously(下意识地)hold poor role models.If,as a child,you observed people whose lives were bad,you may have accepted their fear and pain as normal and gone on to follow what they did.If you do not make strong choices for yourself,you will get the results of the weak choices of others.
    In the field of entertainment,our culture glorifies celebrities.Those stars look great on screen.But when they step off screen,their personal lives may be disastrous.If you are going to follow someone,focus on their talent,not their bad character or unacceptable behaviors.
    Blessed is the person willing to act on their sudden desire to create something unique.Think of the movies,books,teachers,and friends that have affected you most deeply.They touched you because their creations were motivated by inspiration,not desperation.The world is changed not by those who do what has been done before them,but by those who do what has been done inside them.Creative people have an endless resource of ideas.The problem a creator faces is not running out of material;it is what to do with the material knocking at the door of imagination.
    Study your role models,accept the gifts they have given,and leave behind what does not server you.Then you can say,"I stand on the shoulders of my ancestors'tragedies and declare victory,and know that they are cheering on."

51.Imitation proves useful when youC.
A.know you are unique                         
B.lose the balance of life
C.begin to learn something new             
D.get tired of routine practice
52.To avoid the bad result of imitation,we shouldC.
A.forget daily fear and pain                    
B.ask others tor decisions
C.choose the right example
D.stay away from stars
49.According to the author,the world moves on because of those who areB.
A.desperate to influence others with their knowledge
B.ready to turn their original ideas into reality
C.eager to discover what their ancestors did
D.willing to accept others'ideas
50.The trouble a creator faces isD.
A.the lack of strong motivation
B.the absence of practical ideas
C.how to search for more materials
D.how to use imagination creatively
51.What is the author's purpose in writing this passage?A
A.To highlight the importance of creatively.
B.To criticize the characters of role models.
C.To compare imitation with creation.
