16．David will never forget what happened to him yesterday．He was eating something at  home（61）when he received a strange phone call from a hospital．The caller said his son（62）had fallen（fall）to the ground unconscious on the way to schoo1．It was he who took him to the hospital．David rushed to his son's classroom，only （63）to find （find）him listening to the teacher attentively．He  （64）suddenly （sudden）realized he had been cheated，but he felt relieved．Just at that time the phone rang again，（65）saying（say），"Your son is in great danger and he needs （66）an immediate operation which costs 48，000yuan．The doctors here say they will not operate on your son until they receive the money．"When （67）asked（ask）from where the caller had taken his son to hospital，the caller rang off．David gave a big smile and said，"What a pity!"

6．How can you tell if someone's lying？The answer is，they're probably not．
Traditional economics says that people are rational（理智的）beings who will lie if it's to their advantage．A recent university study has shown that，actually，we're pretty honest--especially when we're  at home．
Researchers in Germany phoned people at home and asked them to toss（投擲）a coin．There was a strong financial incentive（刺激） to fake the result：if the coin landed tails-up，the participants  would receive money or a gift ticket，while if the coin landed heads-up，they would get nothing．Because they were  on the phone，they knew there was no risk of getting caught if they lied．
And yet people told the truth．Over hundreds of tosses，a coin will land tails-up roughly 50% of the time．In this study 0ver half the people asked （55.6%） said that the coin landed heads-up，which meant they would receive nothing．
Previous studies had found that people were more dishonest．In those laboratory studies，75% of people reported a winning coin and claimed a reward．So the research team thinks it's being in our own homes which makes us play fair，although it's not yet clear why．
In fact both types of study show people are surprisingly reliable．Even in the laboratory，25% of people  turned down a reward by telling the truth．The researchers say this is because honesty is highly  valued in human society．We care about our  reputation and our sense of ourselves as respectable people．So lying has a psychological  cost and it seems this cost is more important than the financialbenefits of lying．

24．When do people lie according to troditional economics？B
A．When they are at home    
B．When it's to their advantage．
C．When they would receive nothing   
D．When it comes to financial benefits．
25．Which of the following is TRUE according to the research？A
A．There was no risk of getting caught lying if people were on the phone．
B．The participant would receive nothing if he said the coin landed tails-up．
C．The studies could help to correct the mistakes of the participants
D．people would play fair and behave acceptably if invited to the laboratory．
26．Under what circumstance were the participants more dishonest？D
A．On the phone      
B．On the street
C．In their homes     
D．In those laboratory studies
27．Researchers have done an experiment in order toD．
A．find out the rates of tossing a coin．
B．prove the finacial benefits of lying．
D．find out the reason why people play fair．
D．a(chǎn)dvocate honesty is highly valued in society．

4．People have been wondering why elephants do not develop cancer even though they have lifespans（壽命）that are similar to humans，living for around 50 to 70 years．
    Now scientists believe they know why．A team at the University of Chicago，US has found that elephants carry a large number of genes that stop tumors（腫瘤）developing．To be precise，they found 20 copies of an anti-tumor gene called TP53 in elephants．Most other species，including humans，only carry one copy．
    According to the research，the extra copies of the gene improved the animal's sensitivity to DNA damage，which lets the cells quickly kill themselves when damaged before they can go on to form deadly tumors．
"An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals，"the study author Dr Vincent Lynch told The Guardian．If every living cell has the same chance of becoming cancerous（癌變的），large creatures with a long lifespan like whales and elephants should have a greater risk of developing cancer than humans and mice．But across species，the risk of cancer does not show a connection with body mass．
    This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named"Peto's paradox（悖論）"．Biologists believe it results from larger animals using protection that many smaller animals do not．In the elephant's case，the making of TP53 is nature's way of keeping this species alive．
    The study also found that when the same genes were brought to life in mice，they had the same cancer resistance as elephants．This means researchers could use the discovery to develop new treatments that can help stop cancers spreading or even developing in the first place．
"Nature has already figured out how to prevent cancer，"said Joshua Schiffman，a biologist at the School of Medicine，University of Utah，US．"It's up to us to learn how different animals deal with the problem so that we can use those strategies to prevent cancer in people．"
32．Why are elephants unlikely to develop cancer？D
A．They have a rather large body size．
B．Their genes suffer no DNA damage．
C．Certain genes in their body kill existing tumors．
D．They carry many genes to prevent tumors developing．
33．According to the passage，what has been a risk in the evolution of large animals？A
A．Deadly tumors．
B．The huge body mass．
C．Cells killing themselves．
D．Sensitivity to DNA damage．
34．What does the underlined part"This phenomenon"in Paragraph 5 probably refer to？B
A．Larger animals have protection from TP53．
B．The risk of cancer is not related to body size．
C．Larger animals suffer the same risk of cancer as smaller ones．
D．The larger animals are，the bigger risk of cancer they will have．
35．What can be concluded from the passage？C
A．Depending on nature is surely enough to fight against cancer．
B．The TP53 genes have proved useful in stopping cancer in people．
C．Humans are expected to prevent cancer with the making of TP53．
D．The extra copies of elephants'genes are used to cure cancer patients．
