An Ohio State University study also found that black st udents living with a white roommate saw higher ___33___success through out their college careers.

Reading ComprehensionSection AWhile awareness and mastery of skills are important steps in any lea rning process, it is only when conscious skills are put to work that you will experience the involvement and excitement that accompany personal g rowth. The __41__ mimicking 〔模仿〕sounds, the youngster practicing to ride his bicycle, the teenager learning to drive, the adult preparing to bu y a house---all experience a good deal of anticipation (希望), but the anti cipation pales next to the__42__of first communicating verbally or riding a bicycle solo or taking that first drive or moving into that first home.__ 43__, social interaction is the highest degree of personal involvement, the logical peak experience towards what awareness and mastery lead.More than any other experience it is social interaction by which a pe rson __44__, expands, and develops his own personality.__45__, the more involved you are, the more experiences you have, the greater will be the actualization of your personality. If, __46__, you are an active person in your community, your personality will express this activity by its positiv e and __47__nature. If, on the other hand, you are passive, merely allowi ng yourself to be__48__without any involvement in the day-to-day activiti es of your community, you risk boredom and dullness. Much has been wr itten about the 〝mass man〞and about the__49__of the average citizen to affect his own destiny. Involved persons are not mass men or __50__ citizens. // Involvement in your community means developing your com munity and yourself by direct and__51__social interaction. Since this interaction could involve you in any and all of the functions of your commun ity, we suggest here that you select for your involvement activities which are most__52__to you. You might consider your future career plans, hob bies, or educational interests as __53__ for your decision.

Although that is now cha nging, many women still feel angry enough to deface offending advertise ments with stickers protesting, 〝This ad degrades women.〞Why does t his sort of advertising exist? How can advertisers and ad agencies still pr oduce, sometimes, after months of research, advertising that offends the c onsumer?The Advertising Standards Authority, the body which deals with complaints about print media, is carrying out research into how women f eel about the way they are pictured in advertisements. Its conclusions are likely to be what the advertising industry already knows: although wome n are often annoyed by the ads, few feel strongly enough to complain.Women are not the only victims of poor and boring stereotypes —in many TV commercials men are seen either as useless, childish fool s who are unable to perform the simplest household tasks, or as inconsid erate fellows, always on the lookout for an escape to the pub. But it is women who seem to suffer more from the industry’s apparent inability t o put people into an authentic present-day situation.Yet according to Emma Bennett, director of a London advertising agency, women are not aggressive or extremely angry about those stereotypes and sexist advertising. 〝They just find it annoying or tiresome.〞Th ey reluctantly accept outdated stereotypes, but have a sigh of relief when an advertisement really gets it right.〞She says that it is not advertising’s use of the housewife role that bothers women, but the way in which it is handled. 〝The most important thing is the advertisement’s tone of v oice. Women hate being insincerely praised or given desperately down-to-e arth common-sense advice.〞In the end, the responsibility for good advertising must be shar ed between the advertiser, the advertising agency and the consumer. Adve rtising does not set trends but it reflects them. It is up to the consumer t o tell advertisers where they fail, and the process of change will remain slow until people on the receiving end take the business seriously and ma ke their feelings known.56. Despite recent changes in attitudes, some advertisements still fai l to _________.A. change women’s opinions of themselvesB. show any understanding of consumers’feelingsC. persuade the public to buy certain productsD. meet the needs of the advertising industry57. The advertisers don’t give up presenting misleading image of women in ads mainly because __.A. consumers seldom make complaints about itB. they are ignorant about consumers’feelingsC. They aren’t afraid of being complained aboutD. consumers don’t take the advertisements seriously58. According to the author, the most crucial factor in the improve ment of the advertisements is _________.A. the industryB. the advertisersC. the productsD. th e consumers(B)It's finally over. We mean both the Oscar telecast, which ran as long as Gone With the Wind (though with fewer important roles for African Americans), and the three-month death march of critics' citations, guild(行业) awards and expert opinions on who'd win. In case you nodded off, B irdman took Best Picture and Director, and the acting prizes went to Eddi e Redmayne for The Theory of Everything, Julianne Moore for Still Alic e, J.K. Simmons for Whiplash and Patricia Arquette for Boyhood --- four folks whom most people know from the speeches they gave, not the mo vies they were in.This year, the only big hit among the eight Best Picture finalists was American Sniper. The other seven were art-house films. You see, there i s Hollywood, which makes movies the whole world watches, and there is off-Hollywood, which hatches the films that get Oscars. Somebody has t o ask: Why does Hollywood hate what it does for a living?It can't be as simple as "films" are great and "movies" are rubbish. On the Rotten Tomatoes website, which shows the reviews of dozens of critics, Birdman pulled a 93 rating (out of 100) and The Imitation Game an 89. But some popular hits also scored with the critics: 91 for Guardia ns of the Galaxy, 89 for Captain America: The Winter Soldier, 88 for Go ne Girl and a dramatic 96 for The Lego Movie. Audiences liked these fo ur films too, paying more than $1 billion to see them in North American theaters (plus another $1.3 billion abroad).So why weren't at least a couple of these films nominated(提名) for Best Picture? Maybe simply because they were popular. They got their a wards as cash prizes, not Oscar statuettes. The Oscar winners have becom e a category of little films about big diseases. Another disconnect betwee n Oscar voters and moviegoers: ages. The average age of the 6,700 Acad emy members is about 60, and they see most of the nominated films onscreeners at home. Basically, they want movies to be television: educatin g, intimate(亲密的) dramas. The stories they respond to are not of youngs ters on grand quests --- the action-film --- but of unsung heroes battling weakness and approaching death.The very first Oscar party, in 1929, had two Best Picture categories: one for "outstanding picture" (William Wellman's spectacle Wings), the o ther for "unique and artistic picture" (F.YV Murnau's masterpiece Sunrise). Maybe the Academy, obsessed with indie (独立制片的) artistry should re turn to the double award. Then Avatar could win along with The Hurt L ocker, am Gravity with 12 Years a Slave. Next year, even the new Star Wars might have a shot.59. It can be inferred from the last sentence of Paragraph l that ___ _______ .A. not many people saw the four filmsB. awards shouldn't be given to the four peopleC. the four actors and actresses made great speechesD. the four films won the awards as expected60. Why does the author mention these films in Paragraph 2?A. To introduce the great films that are worth watching.B. To explain why some films are given a higher score than others.C. To illustrate there are films welcomed by both viewers and critics.D. To highlight the importance of turning to critics' reviews when ch oosing films.61. Which of the following statements is the author most likely to a gree with?A. Less emphasis should be given to moviegoers' opinions about film s.B. Oscar voters are unsung heroes fighting against weakness.C. Being popular may prevent a film winning Oscar awards.D. It is better to see a film in the cinema than at home.62. What suggestion does the author give about Oscar awards?A. Having more independent film makers nominated for awards.B. Setting up an award for the films different from present winners.C. Improving the standard for outstanding films.D. Giving more chances to the greatest hits.(C)You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward.These optical illusions occur because the brain is constantly matching its model of reality to signals from the body’s sensors and interpreting what must be happening—that your brain must have moved, not the othe r; that downward motions is now normal, so a change from it must now be perceived as upward motion.The sensors that make this magic are of two kinds. Each eye contain s about 120 million rods, which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away.Color vision in each eye comes from six to seven million structures called cones. Under ideal conditions, every cone can 〝see〞the entire ra inbow spectrum of visible colors, but one type of cone is most sensitive to red, another to green, a third to blue.Rods and cones send their messages pulsing an average 20 to 25 tim es per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photograp hs are projected onto screens at 24 frames per second, tricking our eyes i nto seeing a continuous moving picture.Like apparent motion, color vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called 〝the violet hour.〞A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of bl ue and green, and they impart a strange vividness to the garden’s blue f lowers.However, look at a white shirt during the reddish light of sunset, an d you’ll still see it in its 〝true〞color—white, not red. Our eyes are c onstantly comparing an object against its surroundings. They therefore obs erve the effect of a shift in the color of illuminating on both, and adjust accordingly. // The eyes can distinguish several million graduations of ligh t and shade of color. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us.Yet all this is done at the back of each eye by a fabric of sensors, called the retina, about as wide and as thick as a postage stamp. As the Renaissance inventor and artist Leonardo da Vinci wrote in wonder, 〝Wh o would believe that so small a space could contain the images of all the universe?〞63. Visual illusions often take place when the image of reality is __ ____.A. matched to six to seven million structures called cones.B. confused in the body’s sensors of both rods and cones.C. interpreted in the brain as what must be the case.D. signaled by about 120 million rods in the eye.64. The retina send pulses to the brain ______.A. in short wavelengthsB. as color picturesC. by a ganglion cellD. along the optic nerve.65. Twenty-four still photographs are made into a continuous moving picture just because ______.A. the image we see usually stays longer than it actually appears.B. we see an object in comparison with its surroundings.C. the eyes catch million pieces of information continuously.D. rods and cones send messages 20 to 25 times a second.66. The author’s purpose in writing the passage lies in ______.A. showing that we sometimes are deceived by our own eyes.B. informing us about the different functions of the eye organs.C. regretting that we are too slow in the study of eyes.D. marveling at the great work done by the retina.EmpathyLast year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students ha d dropped sharply over the past 10 years. (67)_______ Today, people spe nd more time alone and are less likely to join groups and clubs.Jennifer Freed, a co-director of a teen program, has another explanati on. Turn on the TV, and you’re showered with news and reality shows f ull of people fighting, competing, and generally treating one another with no respect. (68)__________There are good reasons not to follow those bad examples. Humans a re socially related by nature. (69)____ Researchers have also found that e mpathetic teenagers are more likely to have high self-respect. Besides, em pathy can be a cure for loneliness, sadness, anxiety, and fear.Empathy is also an indication of a good leader. In fact, Freed says, many top companies report that empathy is one of the most important thi ngs they look for in new managers. Good social skills, including empath y, are a kind of 〝emotional intelligence〞that will help you succeed in many areas of life. 〝Academics are important. But if you don’t have e motional intelligence, you won’t be as successful in work or in your lov e life.〞she says.What’s the best way to up your EQ? For starters, let down your gu ard and really listen to others. (70) __________To really develop empathy, you’d better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a 〝sharing circle〞with your family, or spend time caring for pets at an animal shelter.第II卷(50’)I. Summary. (10’)How you rank in society has a lot to do with how much you care a bout your fellow man. That’s the main idea of a new paper written by t he psychologists and the social scientists at University of California.The authors write that one’s sense of social class---derived mainly f rom income and education ---〝exerts broad influences on social thought, emotion, and behavior〞. Using various tests that measure empathy, those who consider themselves among the lower classes demonstrate 〝heighten ed vigilance of the social context and another–focused social orientatio n〞. In other words, poorer, less well-educated individuals tend to notice, and care more about, the people around them. 〝Upper-class rank aware ness〞, on the other hand, 〝triggers a focus away from the context towa rd the self, prioritizing self-interest〞.The paper also claims that people with less education and less mone y tend to be more generous with what money they do have. When the question is posed regarding how much people should give to charity, 〝lo wer-class〞ranks suggest a higher percentage of one’s income than the percentage recommended by the wealthy.Another study mentioned in the paper involved giving participants 10 points, which would later be traded in for money. The individuals given the points were to divide them up between themselves and an unknown partner. Guess who shared more of their points?We found that individuals reporting lower subjective socioeconomic st atus gave more to their partner than did upper-socioeconomic-status partici pants.In this context, the next time you’re called 〝low-class〞, consider i t a compliment.I.

Each word can be usedcan lead to increased ___31___but also to a greater likelihood of conflict.Recent reports found that lodging with a student of a different race may decrease ___32___and force students to engage in more ethnically diverse friendships. An Ohio State University study also found that black students living with a white roommate saw higher ___33___success throughout their college careers. Researchers believe this may be caused by social pressure.In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said that “if you’re surrounded by whites, you have something to prove.” Researchers also observed problems resulting from ___34___interracial students in residences.According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so___35___that one roommate will move out. An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester. Grace Kao, a professor at Penn said she was not surprised by the findings. “This may be the first time that some of these students have___36___, and lived, with someone of a different race,” she sai d.At Penn, students are not asked to indicate race when ___37___for housing. “One of the great things about freshman housing is that, with some___38___, the process throws you together randomly,” said Undergraduate Assembly chairman Alec Webley. “This is the definition of integration.”// “I’ve experienced roommate conflicts between interracial students that have both broken down stereotypes and___39___stereotypes,” said one Penn resident advisor (RA). The RA of two years added that while some conflicts “provided more multicultural acceptance and melding (融合),” there were also “jarring cultural resistance.” The RA said that these conflicts have also occurred among roommates of the same race.Kao said she___40___against forming any generalizations based on any one of the studies, noting that more background characteristics of the students need to be studied and explained.III. Reading ComprehensionSection AWhile awareness and mastery of skills are important steps in any learning process, it is only when conscious skills are put to work that you will experience the involvement and excitement that accompany personal growth. The __41__ mimicking (模仿)sounds, the youngster practicing to ride his bicycle, the teenager learning to drive, the adult preparing to buy a house---all experience a good deal of anticipation (希望), but the anticipation pales next to the__42__of first communicating verbally or riding a bicycle solo or taking that first drive or moving into that first home.__43__, social interaction is the highest degree of personal involvement, the logical peak experience towards what awareness and mastery lead.More than any other experience it is social interaction by which a person __44__, expands, and develops his own personality.__45__, the more involved you are, the more experiences you have, the greater will be the actualization of your personality. If, __46__, you are an active person in your community, your personality will express this activity by its positive and __47__nature. If, on the other hand, you are passive, merely allowing yourself to be__48__without any involvement in the day-to-day activities of your community, you risk boredom and dullness. Much has been written about the “mass man” and about the__49__of the average citizen to affect his o wn destiny. Involved persons are not mass men or __50__ citizens. // Involvement in your community means developing your community and yourself by direct and__51__social interaction. Since this interaction could involve you in any and all of the functions of your community, we suggest here that you select foryour involvement activities which are most__52__to you. You might consider your future career plans, hobbies, or educational interests as __53__ for your decision. For once you begin to be involved in your community and once you experience your own __54__ in self-awareness through community awareness, you may very well find social interaction a life-time project, __55__where your community may be or how it may change.41.A. girl B. boy C. infant D. animal42.A. realization B. surprise C. relief D. excitement43.A.

Although that is now changing, many women still feel angry enough to deface offending advertisements with stickers protesting, “This ad degrades women.” Why does this sort of advertising exist? How can advertisers and ad agencies still produce, sometimes, after months of research, advertising that offends the consumer?The Advertising Standards Authority, the body which deals with complaints about print media, is carrying out research into how women feel about the way they are pictured in advertisements. Its conclusions are likely to be what the advertising industry already knows: although women are often annoyed by the ads, few feel strongly enough to complain.Women are not the only victims of poor and boring stereotypes—in many TV commercials men are seen either as useless, childish fools who are unable to perform the simplest household tasks, or as inconsiderate fellows, always on the lookout for an escape to the pub. But it is women who seem to suffer more from the industry’s apparent inability to put people into an authentic present-day situation.Yet according to Emma Bennett, director of a London advertising agency, women are not aggressive or extremely angry about those stereotypes and sexist advertising. “They just find it annoying or tiresome.” They reluctantly accept outdated stereotypes, but have a sigh of relief when an advertisement really gets it right.” She says that it is not advertising’s use of the housewife role that bothers women, but the way in which it is handled. “The most important thing is the advertisement’s tone of voice. Women hat e being insincerely praised or given desperately down-to-earth common-sense advice.”In the end, the responsibility for good advertising must be shared between the advertiser, theadvertising agency and the consumer. Advertising does not set trends but it reflects them. It is up to the consumer to tell advertisers where they fail, and the process of change will remain slow until people on the receiving end take the business seriously and make their feelings known.56. Despite recent changes in attitudes, some advertisements still fail to _________.A. change women’s opinions of themselvesB. show any understanding of consumers’ feelingsC. persuade the public to buy certain productsD. meet the needs of the advertising industry57. The advertisers don’t give up presenting misleading image of women in ads mainly because __.A. consumers seldom make complaints about itB. they are ignorant about consumers’ feelingsC. They aren’t afraid of being complained aboutD. consumers don’t take the advertisem ents seriously58. According to the author, the most crucial factor in the improvement of the advertisementsis _________.A. the industryB. the advertisersC. the productsD. the consumers(B)It's finally over. We mean both the Oscar telecast, which ran as long as Gone With the Wind (though with fewer important roles for African Americans), and the three-month death march of critics' citations, guild(行业) awards and expert opinions on who'd win. In case you nodded off, Birdman took Best Picture and Director, and the acting prizes went to Eddie Redmayne for The Theory of Everything, Julianne Moore for Still Alice, J.K. Simmons for Whiplash and Patricia Arquette for Boyhood --- four folks whom most people know from the speeches they gave, not the movies they were in.This year, the only big hit among the eight Best Picture finalists was American Sniper. The other seven were art-house films. You see, there is Hollywood, which makes movies the whole world watches, and there is off-Hollywood, which hatches the films that get Oscars. Somebody has to ask: Why does Hollywood hate what it does for a living?It can't be as simple as "films" are great and "movies" are rubbish. On the Rotten Tomatoes website, which shows the reviews of dozens of critics, Birdman pulled a 93 rating (out of 100) and The Imitation Game an 89. But some popular hits also scored with the critics: 91 for Guardians of the Galaxy, 89 for Captain America: The Winter Soldier, 88 for Gone Girl and a dramatic 96 for The Lego Movie. Audiences liked these four films too, paying more than $1 billion to see them in North American theaters (plus another $1.3 billion abroad).So why weren't at least a couple of these films nominated(提名) for Best Picture? Maybe simply because they were popular. They got their awards as cash prizes, not Oscar statuettes. The Oscar winners have become a category of little films about big diseases. Another disconnect between Oscar voters and moviegoers: ages. The average age of the 6,700 Academy members is about 60, and they see most of the nominated films on screeners at home. Basically, they want movies to be television: educating, intimate(亲密的) dramas. The stories they respond to are not of youngsters on grand quests --- the action-film --- but of unsung heroes battling weakness and approaching death.The very first Oscar party, in 1929, had two Best Picture categories: one for "outstanding picture" (William Wellman's spectacle Wings), the other for "unique and artistic picture" (F.YV Murnau's masterpiece Sunrise). Maybe the Academy, obsessed with indie (独立制片的) artistryshould return to the double award. Then Avatar could win along with The Hurt Locker, am Gravity with 12 Years a Slave. Next year, even the new Star Wars might have a shot.59. It can be inferred from the last sentence of Paragraph l that __________ .A. not many people saw the four filmsB. awards shouldn't be given to the four peopleC. the four actors and actresses made great speechesD. the four films won the awards as expected60. Why does the author mention these films in Paragraph 2?A. To introduce the great films that are worth watching.B. To explain why some films are given a higher score than others.C. To illustrate there are films welcomed by both viewers and critics.D. To highlight the importance of turning to critics' reviews when choosing films.61. Which of the following statements is the author most likely to agree with?A. Less emphasis should be given to moviegoers' opinions about films.B. Oscar voters are unsung heroes fighting against weakness.C. Being popular may prevent a film winning Oscar awards.D. It is better to see a film in the cinema than at home.62. What suggestion does the author give about Oscar awards?A. Having more independent film makers nominated for awards.B. Setting up an award for the films different from present winners.C. Improving the standard for outstanding films.D. Giving more chances to the greatest hits.(C)You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward.These optical illusions occur because the brain is constantly matching its model of reality to signals from the body’s sensors and interpreting what must be happening—that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion.The sensors that make this magic are of two kinds. Each eye contains about 120 million rods, which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away.Color vision in each eye comes from six to seven million structures called cones. Under ideal conditions, every cone can “see” the entire rainbow spectrum of visible colors, but one type of cone is most sensitive to red, another to green, a third to blue.Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture.Like apparent motion, color vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called “the violet hour.” A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden’s blue flowers.However, look at a white shirt during the reddish light of sunset, and you’ll still see it in its“true” color—white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color of illuminating on both, and adjust accordingly. // The eyes can distinguish several million graduations of light and shade of color. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us.Yet all this is done at the back of each eye by a fabric of sensors, called the retina, about as wide and as thick as a postage stamp. As the Renaissance inventor and artist Leonardo da Vinci wrote in wonder, “Who would believe that so small a space could contain the images of all the universe?”63. Visual illusions often take place when the image of reality is ______.A. matched to six to seven million structures called cones.B. confused in t he body’s sensors of both rods and cones.C. interpreted in the brain as what must be the case.D. signaled by about 120 million rods in the eye.64. The retina send pulses to the brain ______.A. in short wavelengthsB. as color picturesC. by a ganglion cellD. along the optic nerve.65. Twenty-four still photographs are made into a continuous moving picture just because ______.A. the image we see usually stays longer than it actually appears.B. we see an object in comparison with its surroundings.C. the eyes catch million pieces of information continuously.D. rods and cones send messages 20 to 25 times a second.66. The author’s purpose in writing the passage lies in ______.A. showing that we sometimes are deceived by our own eyes.B. informing us about the different functions of the eye organs.C. regretting that we are too slow in the study of eyes.D. marveling at the great work done by the retina.EmpathyLast year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students had dropped sharply over the past 10 years.(67)_______ Today, people spend more time alone and are less likely to join groups and clubs.Jennifer Freed, a co-director of a teen program, has another explanation. Turn on the TV, and you’re showered with news and reality shows full of people fighting, competing, and generally treating one another with no respect. (68)__________There are good reasons not to follow those bad examples. Humans are socially related by nature.(69)____ Researchers have also found that empathetic teenagers are more likely to have high self-respect. Besides, empathy can be a cure for loneliness, sadness, anxiety, and fear.Empathy is also an indication of a good leader. In fact, Freed says, many top companies report that empathy is one of the most important things they look for in new managers. Good social skills, including empathy, are a kind of “emotional intelligence” that will help you succeed in many areas of life. “Academics are important. But if you don’t have emotional intelligence, you won’t be as successful in work or in your love life.” she says.What’s the best way to up your EQ? For starters, let down your guard and really listen to others.(70) __________To really develop empathy, you’d better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a “sharing circle” with your family, or spend time caring for pets at an animal shelter.第II卷(50’)I. Summary. (10’)How you rank in society has a lot to do with how much you care about your fellow man. That’s the main idea of a new paper written by the psychologists and the social scientists at University of California.The authors write that one’s sense of social class---derived mainly from income and education ---“exerts broad influences on social thought, emotion, and behavior”. Using var ious tests that measure empathy, those who consider themselves among the lower classes demonstrate “heightened vigilance of the social context and another–focused social orientation”. In other words, poorer, less well-educated individuals tend to notice, a nd care more about, the people around them. “Upper-class rank awareness”, on the other hand, “triggers a focus away from the context toward the self, prioritizing self-interest”.The paper also claims that people with less education and less money tend to be more generous with what money they do have. When the question is posed regarding how much people should give to charity, “lower-class” ranks suggest a higher percentage of one’s income than the percentage recommended by the wealthy.Another study mentioned in the paper involved giving participants 10 points, which would later be traded in for money. The individuals given the points were to divide them up between themselves and an unknown partner. Guess who shared more of their points?We found that individuals reporting lower subjective socioeconomic status gave more to their partner than did upper-socioeconomic-status participants.In this context, the next time you’re called “low-class”, consider it a compliment.I.

Each word can be usedcan lead to increased ___31___but also to a greater likelihood of conflict.Recent reports found that lodging with a student of a different race may decrease ___32___and force students to engage in more ethnically diverse friendships. An Ohio State University study also found that black students living with a white roommate saw higher ___33___success throughout their college careers. Researchers believe this may be caused by social pressure.In a New York Times article, Sam Boakye – the only black student on his freshman year floor -said th at “if you’re surrounded by whites, you have something to prove.” Researchers also observed problems resulting from ___34___interracial students in residences.According to two recent studies, randomly assigned roommates of different races are more likely to experience conflicts so___35___that one roommate will move out. An Indiana University study found that interracial roommates were three times as likely as two white roommates to no longer live together by the end of the semester. Grace Kao, a professor at Penn said she was not surprised by the findings. “This may be the first time that some of these students have___36___, and lived, with someone of a different race,” she said.At Penn, students are not asked to indicate race when ___37___for housing. “On e of the great things about freshman housing is that, with some___38___, the process throws you together randomly,” said Undergraduate Assembly chairman Alec Webley. “This is the definition of integration.”// “I’ve experienced roommate conflicts between interracial students that have both broken down stereotypes and___39___stereotypes,” said one Penn resident advisor (RA).

Reading ComprehensionSection AWhile awareness and mastery of skills are important steps in any learning process, it is only when conscious skills are put to work that you will experience the involvement and excitement that accompany personal growth. The __41__ mimicking (模仿)sounds, the youngster practicing to ride his bicycle, the teenager learning to drive, the adult preparing to buy a house---all experience a good deal of anticipation (希望), but the anticipation pales next to the__42__of first communicating verbally or riding a bicycle solo or taking that first drive or moving into that first home.__43__, social interaction is the highest degree of personal involvement, the logical peak experience towards what awareness and mastery lead.More than any other experience it is social interaction by which a person __44__, expands, and develops his own personality.__45__, the more involved you are, the more experiences you have, the greater will be the actualization of your personality. If, __46__, you are an active person in your community, your personality will express this activity by its positive and __47__nature. If, on the other hand, you are passive, merely allowing yourself to be__48__without any involvement in theday-to-day activities of your community, you risk boredom and dullness. Much has been written about the “mass man” and about the__49__of the average citizen to affect his own destiny. Involved persons are not mass men or __50__ citizens. // Involvement in your community means developing your community and yourself by direct and__51__social interaction. Since this interaction could involve you in any and all of the functions of your community, we suggest here that you select for your involvement activities which are most__52__to you. You might consider your future career plans, hobbies, or educational interests as __53__ for your decision. For once you begin to be involved in your community and once you experience your own __54__ in self-awareness through community awareness, you may very well find social interaction a life-time project, __55__where your community may be or how it may change.41.A. girl B. boy C. infant D. animal42.A. realization B. surprise C. relief D. excitement43.A.

Although that is now changing, many women still feel angry enough to deface offending advertisements with stickers protesting, “This ad degrades women.” Why does this sort of advertising exist? How can advertisers and ad agencies still produce, sometimes, after months of research, advertising that offends the consumer?The Advertising Standards Authority, the body which deals with complaints about print media, is carrying out research into how women feel about the way they are pictured in advertisements. Its conclusions are likely to be what the advertising industry already knows: although women are often annoyed by the ads, few feel strongly enough to complain.Women are not the only victims of poor and boring stereotypes—in many TV commercials men are seen either as useless, childish fools who are unable to perform the simplest household tasks, or as inconsiderate fellows, always on the lookout for an escape to the pub. But it is women who seem to suffer more from the industry’s apparent inability to put people into an authentic present-day situation.Yet according to Emma Bennett, director of a London advertising agency, women are not aggressive or extremely angry about those stereotypes and sexist advertising. “They just find itannoying or tiresome.” They reluctantly accept outdated stereotypes, but have a sigh of relief when an advertisement really gets it right.” She says that it is not advertising’s use of the housewife role that bothers women, but the way in which it is handled. “The most important thing is the advertisement’s tone of voice. Women hate being insincerely praised or given desperately down-to-earth common-sense adv ice.”In the end, the responsibility for good advertising must be shared between the advertiser, the advertising agency and the consumer. Advertising does not set trends but it reflects them. It is up to the consumer to tell advertisers where they fail, and the process of change will remain slow until people on the receiving end take the business seriously and make their feelings known.56. Despite recent changes in attitudes, some advertisements still fail to _________.A. change women’s opinions of themselvesB. show any understanding of consumers’ feelingsC. persuade the public to buy certain productsD. meet the needs of the advertising industry57. The advertisers don’t give up presenting misleading image of women in ads mainly because __.A. consumers seldom make complaints about itB. they are ignorant about consumers’ feelingsC. They aren’t afraid of being complained aboutD. consumers don’t take the advertisements seriously58. According to the author, the most crucial factor in the improvement of the advertisementsis _________.A. the industryB. the advertisersC. the productsD. the consumers(B)It's finally over. We mean both the Oscar telecast, which ran as long as Gone With the Wind (though with fewer important roles for African Americans), and the three-month death march of critics' citations, guild(行业) awards and expert opinions on who'd win. In case you nodded off, Birdman took Best Picture and Director, and the acting prizes went to Eddie Redmayne for The Theory of Everything, Julianne Moore for Still Alice, J.K. Simmons for Whiplash and Patricia Arquette for Boyhood --- four folks whom most people know from the speeches they gave, not the movies they were in.This year, the only big hit among the eight Best Picture finalists was American Sniper. The other seven were art-house films. You see, there is Hollywood, which makes movies the whole world watches, and there is off-Hollywood, which hatches the films that get Oscars. Somebody has to ask: Why does Hollywood hate what it does for a living?It can't be as simple as "films" are great and "movies" are rubbish. On the Rotten Tomatoes website, which shows the reviews of dozens of critics, Birdman pulled a 93 rating (out of 100) and The Imitation Game an 89. But some popular hits also scored with the critics: 91 for Guardians of the Galaxy, 89 for Captain America: The Winter Soldier, 88 for Gone Girl and a dramatic 96 for The Lego Movie. Audiences liked these four films too, paying more than $1 billion to see them in North American theaters (plus another $1.3 billion abroad).So why weren't at least a couple of these films nominated(提名) for Best Picture? Maybe simply because they were popular. They got their awards as cash prizes, not Oscar statuettes. The Oscar winners have become a category of little films about big diseases. Another disconnect between Oscar voters and moviegoers: ages. The average age of the 6,700 Academy members is about 60,and they see most of the nominated films on screeners at home. Basically, they want movies to be television: educating, intimate(亲密的) dramas. The stories they respond to are not of youngsters on grand quests --- the action-film --- but of unsung heroes battling weakness and approaching death.The very first Oscar party, in 1929, had two Best Picture categories: one for "outstanding picture" (William Wellman's spectacle Wings), the other for "unique and artistic picture" (F.YV Murnau's masterpiece Sunrise). Maybe the Academy, obsessed with indie (独立制片的) artistry should return to the double award. Then Avatar could win along with The Hurt Locker, am Gravity with 12 Years a Slave. Next year, even the new Star Wars might have a shot.59. It can be inferred from the last sentence of Paragraph l that __________ .A. not many people saw the four filmsB. awards shouldn't be given to the four peopleC. the four actors and actresses made great speechesD. the four films won the awards as expected60. Why does the author mention these films in Paragraph 2?A. To introduce the great films that are worth watching.B. To explain why some films are given a higher score than others.C. To illustrate there are films welcomed by both viewers and critics.D. To highlight the importance of turning to critics' reviews when choosing films.61. Which of the following statements is the author most likely to agree with?A. Less emphasis should be given to moviegoers' opinions about films.B. Oscar voters are unsung heroes fighting against weakness.C. Being popular may prevent a film winning Oscar awards.D. It is better to see a film in the cinema than at home.62. What suggestion does the author give about Oscar awards?A. Having more independent film makers nominated for awards.B. Setting up an award for the films different from present winners.C. Improving the standard for outstanding films.D. Giving more chances to the greatest hits.(C)You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward.These optical illusions occur because the brain is constantly matching its model of reality to signals from the body’s sensors and interpreting what must be happening—that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion.The sensors that make this magic are of two kinds. Each eye contains about 120 million rods, which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away.Color vision in each eye comes from six to seven million structures called cones. Under ideal conditions, every cone can “see” the entire rainbow spectrum of visible colors, but one type of cone is most sensitive to red, another to green, a third to blue.Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes intoseeing a continuous moving picture.Like apparent motion, color vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called “the violet hour.” A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden’s blue flowers.However, look at a white shirt during the reddis h light of sunset, and you’ll still see it in its “true” color—white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color of illuminating on both, and adjust accordingly. // The eyes can distinguish several million graduations of light and shade of color. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us.Yet all this is done at the back of each eye by a fabric of sensors, called the retina, about as wide and as thick as a postage stamp. As the Renaissance inventor and artist Leonardo da Vinci wrote in wonder, “Who would believe that so small a space could contain the ima ges of all the universe?”63. Visual illusions often take place when the image of reality is ______.A. matched to six to seven million structures called cones.B. confused in the body’s sensors of both rods and cones.C. interpreted in the brain as what must be the case.D. signaled by about 120 million rods in the eye.64. The retina send pulses to the brain ______.A. in short wavelengthsB. as color picturesC. by a ganglion cellD. along the optic nerve.65. Twenty-four still photographs are made into a continuous moving picture just because ______.A. the image we see usually stays longer than it actually appears.B. we see an object in comparison with its surroundings.C. the eyes catch million pieces of information continuously.D. rods and cones send messages 20 to 25 times a second.66. The author’s purpose in writing the passage lies in ______.A. showing that we sometimes are deceived by our own eyes.B. informing us about the different functions of the eye organs.C. regretting that we are too slow in the study of eyes.D. marveling at the great work done by the retina.EmpathyLast year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students had dropped sharply over the past 10 years.(67)_______ Today, people spend more time alone and are less likely to join groups and clubs.Jennifer Freed, a co-director of a teen program, has another explanation. Turn on the TV, and you’re showered with news and reality shows full of people fighting, competing, and generally treating one another with no respect. (68)__________There are good reasons not to follow those bad examples. Humans are socially related by nature.(69)____ Researchers have also found that empathetic teenagers are more likely to have high self-respect. Besides, empathy can be a cure for loneliness, sadness, anxiety, and fear.Empathy is also an indication of a good leader. In fact, Freed says, many top companies report that empathy is one of the most important things they look for in new managers. Good social skills, including empathy, are a kind of “emotional intelligence” that will help you succeed in many areas of life. “Academics are important. But if you don’t have emotional intelligence, you won’t be as successful in work or in your love life.” she says.What’s the best way to up your EQ? For starters, let down your guard and really listen to others.(70) __________To really develop empathy, you’d better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a “sharing circle” with your family, or spend time caring for pets at an animal shelter.第II卷(50’)I. Summary. (10’)How you rank in society has a lot to do with how much you care about your fellow man. That’s the main idea of a new paper written by the psychologists and the social scientists at University of California.The authors write that one’s sense of social class---derived mainly from income and education ---“exerts broad influences on social thought, emotion, and behavior”. Using various tests that measure empathy, those who consider themselves among the lowe r classes demonstrate “heightened vigilance of the social context and another–focused social orientation”. In other words, poorer, less well-educated individ uals tend to notice, and care more about, the people around them. “Upper-class rank awareness”, on the other hand, “triggers a focus away from the context toward the self, prioritizing self-interest”.The paper also claims that people with less education and less money tend to be more generous with what money they do have. When the question is posed regarding how much people should give to charity, “lower-class” ranks suggest a higher percentage of one’s income than the percentage recommended by the wealthy.Another study mentioned in the paper involved giving participants 10 points, which would later be traded in for money. The individuals given the points were to divide them up between themselves and an unknown partner. Guess who shared more of their points?We found that individuals reporting lower subjective socioeconomic status gave more to their partner than did upper-socioeconomic-status participants.In this context, the next time you’re called “low-class”, consider it a compliment.I.
