14．Tu Youyou has become the first Chinese woman to win a Nobel Prize，for her work in helping to create an anti-malaria（疟疾） medicine．The 84-year-old's route to the honour has been anything but traditional．In China，she is being called the"three nos"winner：no medical degree，no doctorate，and she's never worked overseas．
In 1967，malaria，a then deadly disease，spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam．A secret research unit"Mission 523"was formed to find a cure for the illness．Two years later，Tu Youyou was instructed to become the new head of"Mission 523"．
"Mission523"read ancient books carefully for a long time to find historical methods of fighting malaria．When she started her search for an anti-malarial drug，more than 240，000compounds（化合物） around the world had already been tested，without any success．Finally，the team found a brief reference to one substance，sweet wormwood（青蒿），which had been used to treat malaria in China around 400AD．The team took out one active compound in wormwood，and then tested it．But nothing was effective until Tu Youyou returned to the original ancient text．After another careful reading，she changed the drug recipe one final time，heating the compound without allowing it to reach boiling point．
After the drug showed promising results in mice and monkeys，Tu Youyou volunteered to be the first human recipient of the new drug．"
In any case，Tu Youyou is consistently praised for her drive and passion．One former colleague．Lianda Li，says Ms Tu is"unsociable and quite straightforward"，adding that"if she disagrees with something，she will say it．"
Another colleague，Fuming Liao，who has worked with Tu Youyou for more than 40years，describes her as a"tough and stubborn woman"．Stubborn enough to spend decades piecing together ancient texts，she applies them to modern scientific practices．The result has saved millions of lives．

18．A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world．The boy walked a long way，and finally came upon the beautiful castle where the wise man lived．
On entering the main room of the castle，the boy was quite surprised：tradesmen coming and going，people chatting in the corners，and a small orchestra playing soft music．The wise man talked with everyone，and the boy had to wait for two hours before it was his turn．
The wise man listened carefully to the boy's explanation of why he had come，but told him that he didn't have time just then to explain the secret of happiness．He suggested that the boy look around the palace and return in two hours．
"Meanwhile，I want to ask you to do something，"said the wise man，handing the boy a teaspoon that held two drops of oil．"As you wander around，carry this spoon with you without allowing the oil to spill（泼洒）．"
The boy began to walk up and down stairs of the palace，keeping his eyes fixed on the spoon．After two hours，he returned to the wise man．
"Well，"asked the wise man，"Did you see the Persian tapestries（挂毯）in the hall？Did you see the garden that took the master gardener ten years to create？"The boy was embarrassed，and replied that he had observed nothing．His only concern had been not to spill the oil．
"Then go back and observe the wonders of my world，"said the wise man．The boy picked up the spoon and returned to his exploration of the palace．This time he observed all of the works of art on the ceilings and the walls．When he returned，he described in detail everything he had seen．
"But where are the drops of oil？"asked the wise man．Looking down at the spoon he held，the boy saw that the oil was gone．

8．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 （认知的） 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．
62．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．
63．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
64．It can be inferred from the passage that in a cognitive interview，the interviewer mainly plays aA role．
A．directing
B．questioning
C．disappointing
D．interrupting
65．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．
