2．When an emergency situation occurs，observers are more likely to take action if there are few or no other witnesses．This phenomenon is referred to as the bystander effect．
The bystander effect is also called the Genovese effect，which is named after Catherine"Kitty"Genovese，a young woman who was cruelly murdered on March 13，1964．Early in the morning，28-year-old Genovese was returning home from work．As she approached her apartment entrance，she was attacked and stabbed （刺） by a man later identified as Winston Moseley．Despite Genovese's repeated cries for help，none of the dozen or so people in the nearby apartment building who heard her cries called police for help．The attack first began at 3：20，but it was not until 3：50 that someone first contacted police．
Many psychologists were set thinking by the incident，as well as most Americans．As the conclusion，the bystander effect came out and later proved by a series of studies and experiments．
There are two major factors that contribute to the bystander effect．First，the presence of other people creates a division of responsibility．Because there are other observers，individuals do not feel as much pressure to take action，since the responsibility to take action is thought to be shared among all of those present．The second reason is the need to behave in correct and socially acceptable ways．When other observers fail to react，individuals often take this as a signal that a response is not needed or not appropriate．
Other researchers have found that onlookers are less likely to take action if the situation is ambiguous．In the case of Kitty Genovese，many of the 38 witnesses reported that they believed that they were witnessing a"lovers'quarrel"，and did not realize that the young woman was actually being murdered．
61．The bystander effect is also called the Genovese effect becauseBa woman surnamed Genovese．
A．it somehow caused the murder of    
B．its discovery resulted from the murder of
C．it was actually discovered by

62．Genovese was murderedD
A．while she was going out                                 
B．in her apartment
C．halfway home

A．They believed in the bystander effect．
B．They thought someone else might help her．
C．They didn't think they should help．
D．They didn't think she needed help．
64．Before deciding to offer help，observers mayC，according to the psychol
ists．
A．wait for sort of a signal                          
B．hesitate and estimate the risk of getting hurt
C．want to be sure it's appropriate to react     
D．wonder if the victim is worth helping
65．The article seems to suggest that，if there had beenBobservers，Genovese might not have been murdered．
A．no

19．Speaking two languages can actually help offset（抵消） some effects of aging on the brain，a new study has found．
Researchers tested how long it took participants to switch from one cognitive（認(rèn)知的） task to another，something that's known to take longer for older adults，said lead researcher，Brian Gold，a neuroscientist at the University of Kentucky．
Gold's team compared task-switching speeds for younger and older adults，knowing they would find slower speeds in the older population because of previous studies．However，they found that older adults who spoke two languages were able to switch mental activities faster than those didn't．The study only looked at life-long bilinguals，defined in study as people who had spoken a second language daily since they were at least 10years old．
Gold and his team asked 30people，either bilingual or monolingual，to have a series of tests．They found that bilingual people were not only able to switch tasks faster，they had different brain activity than their monolingual peers．
Kristina called bilingualism"a beautiful natural experiment"，because people grow up speaking two languages，and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them．
Gold said he grew up in Montreal，where he spoke French at school and English at home，prompting relatives to question whether his French language immersion（專心）would somehow hinder his ability to learn English．
"Until very recently，learning a second language in childhood was thought of as dangerous，"he said．"Actually，it's beneficial．"

29．What's the main idea of the passage？A
A．Researchers found that bilingual people can slow down the speed or aging on the brain and respond fast．
B．Researchers found that bilingual people respond slowly．
C．Researchers found that speaking two languages is important．
D．Researchers found that bilingual people are great．
30．Which of the following is TRUE according to the passage？C
A．Older bilinguals can't respond faster in mind．
B．Young bilinguals can respond faster in mind than those monolinguals．
C．Older adults speaking a second language daily since they were at least 10years old can respond faster than those who don't．
D．Bilingual children respond slower in mind than those monolinguals．
31．In Gold's opinion，learning a second language in childhood isD．
A．dangerous to children                 
B．not beneficial to children
C．dangerous but beneficial to children       
D．not dangerous but beneficial to children．

3．"Dr．Papaderos，what is the meaning of life？"
The usual laughter followed，and people stirred（騷動(dòng)）to go．
Papaderos held up his hand and looked at me for a long time，asking ith his eyes if I was serious and seeing from my eyes that I was．
"I will answer your question．"
Taking his wallet out of his hip pocket，he fished into a leather billfold and brought out a very small round mirror，about the size of a quarter．And what he said went like this：
"When I was a small child，during the war，we were very poor and we lived in a remote village．One day，on the road，I found the broken pieces of a mirror．
"I tried to find all the pieces and put them together，but it was not possible，so I kept only the largest piece．This one，and，by scratching it on a stone，I made it round．I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun woul never shine-in deep holes and cracks and dark closets．It became a game for me to get light into the most inaccessible （難達(dá)到的） places I could find．
"As I became a man，I grew to understand that this was not just a child's game but a metaphor for what I might do with my life．I came to understand that I am not the light or the source of light．But light-truth，understanding，and knowledge-is there，and it will shine in many dark places onlyif I reflect it．
"I am a fragment（碎片）of a mirror whose whole design and shape l do not know．Nevertheless，with what I have I can reflect light into the dark places of this world-into the black places in the hearts of men-and change some things in some people．Perhaps others may see and do likewise．This is what I am about．This is the meaning of my life．"

21．Why did Dr．Papaderos like the small round mirror so much as a child？B
A．Because he was too poor to afford other toys．
B．Because it could shine the places where the sun couldn't reach．
C．Because he believed it would bring good luck to him．
D．Because it told him a lot about what life really meant to him．
22．The underlined"metaphor"in the 8th paragraph most probably meansA．
A．symbol         B．source            C．light     D．purpose
23．Which of the following might be the best title for the passage？D
A．A Special Game in the Childhood      B．A Piece of Mirror
C．Dr．Papaderos'Experience            D．The Meaning of Life．
