Our research included a troubling, yet unsurprising, finding: women are less comfortable negotiating a raise than men.In a follow-up study, which is an extension of our ongoing research on workplace issues, we examined the relationship between gender, race, and asking for a salary increase. As part of our research, we surveyed a racially diverse group of 550 African-Americans, 550 Asian-Americans, 550 Hispanic/Latino Americans, and 350 white Americans about raise negotiations. Our survey found that men are more comfortable requesting a raise, that they are more likely to have asked for a raise during their careers, and that they ask for more money than women. While gender was a bigger factor than race in salary negotiations, we found significant racial differences as well. And when examining race and gender together, there were multiplicative effects.Just over half of our survey respondents have asked for a raise at some point in their career. As we found before, men are more likely to ask for a raise than women. And when it comes to differences among racial backgrounds, white Americans were the most likely to have asked for a salary increase while Asian Americans were the least likely.The effects multiply when we factor in both gender and race. The biggest disparity: white men are 1.8 times more likely than Asian-American women to have asked for a raise. Across all racial backgrounds, the men were more likely to have asked for a raise than women, although Asian-American men were not far ahead of the average for all women. Nearly the same percentage of white, Hispanic or Latina, and black women have asked for raises.Similarly, although black men are most comfortable asking for a raise, they are less likely than white men to have asked for a raise before. If black men a nd women are the most comfortable asking for a raise, why aren‟t they asking? Although this question has no simple answer, a possible explanation is they aren‟t confident a raise would be granted.1. We can learn from the second paragraph that_____.A. sex and race all exert a vital impact on negotiating salaryB. race plays a more crucial role than sex in salary negotiationC. many non-whites are seriously discriminated in present workplaceD. men ask for more money than women when negotiating salary increase2. Which of the following statements is True according to the third paragraph?A. Women are less likely to ask for an increaseB. Asian Americans tend to ask for more moneyC. less than 50% of employees work for interestD. white Americans long for protecting their right3. The word disparity in paragraph 4 is closest in meaning to____.A. similarityB. differenceC. featureD. variation4. Why don‟t black men and women ask for a salary raise?A. they know their bosses are meanB. they fear losing face in publicC. their demand may not be satisfiedD. their confidence may fade gradually5. The author‟s attitude to employees‟ asking for salary raises seems to be___.A. unconcernedB. supportiveC. criticalD. analytical第二篇：来源：2017—4—30 万古杂志字数：390Scientists working on animal cognition often dwell on their desire to talk to the animals. Oddly enough, this particular desire must have passed me by, because I have never felt it. I am not waiting to hear what my animals have to say about themselves, taking the rather Wittgensteinian position that their message might not be all that enlightening. Even with respect to my fellow humans, I am dubious that language tells us what is going on in their heads. I am surrounded by colleagues who study members of our species by presenting them with questionnaires. They trust the answers they receive and have ways, they assure me, of checking their veracity. But who says that what people say about themselves reveals actual emotions and motivations?This might be true for simple attitudes free from moralizations (…What is your favorite music?‟), but it seems almost pointless to ask people about their love life, eating habits, or treatment of others (…Are you pleasant to work with?‟). It i s far too easy to invent post-hoc reasons for one‟s behavior, to downplay excessive eating or drinking, or to present oneself as more admirable than one really is.Since we routinely express ideas and feelings in language, we can be forgiven for assigning a role to it, but isn‟t it remarkable how often we struggle to find our words? It‟s not that we don‟t know what we thought or felt, but we just can‟t put our verbal finger on it. This would of course be wholly unnecessary if thoughts and feelings were linguistic products to begin with. In that case, we‟d expect a waterfall of words!It is now widely accepted that, even though language assists human thinking by providing categories and concepts, it is not the stuff of thought. We don‟t actually need language in order to think. The Swiss pioneer of cognitive development, Jean Piaget, most certainly was not ready to deny thought to preverbal children, which is why he declared cognition to be independent of language. With animals, the situation is similar.There is a notable irony here. In an earlier age, the absence of language was used as an argument against the existence of thought in other species. Today I find myself upholding the position that the manifest reality of thinking by nonlinguistic creatures argues against the importance of language.1. The author‟s attitude toward scientists‟ thirst for talking with animals seems to be____.A. supportiveB. opposedC. indifferentD. sarcastic2. It is implied in the second paragraph thatA. reliable answers may depend on sufficient surveysB. issues concerning morality are easily to be made upC. everyone has his/her story unwilling to be toldD. it might be better for one to be frank to others3. Language is assigned a role becauseA. human beings use it to convey thoughts and emotionsB. it has been recording what human beings thoughtC. it has produced human beings‟ ideas and feelingsD. human beings use it to produce what do not exist4. It can be inferred that animals‟ languageA. has little to do with people‟s languageB. is identical to human beings‟ thoughtC. has little to do with their own thoughtD. is identical to human beings‟ language5. The most appropriate title of this passage might beA. Language and Thought: A Mysterious RelationshipB. Language and Thought: A Never-ending DiscussionC. Language and Thought: Not As Funny As We ThinkD. Language and Thought: Not Making a Good Match第三篇：“Hello Happiness,” a new video from Coca-Cola, opens with footage of migrant laborers in Dubai, standing before dawn in a patch of dirt as they wait for a van to pull up and shuttle them to work. Later, we cycle through shots of grim-faced men in work clothes—slouched on the bus as the sun rises, hunched on sagging bunk beds, crowded on the floor of a small room during mealtime with their elbows nearly touching. They tell us that they love and miss their families, and that they wish they could hear their children‟s voices more often.We learn that these workers make about six dollars per day, and that it costs nearly a dollar per minute to call home—so phone calls are rare. Then the screen goes red, the music brightens, and we are posed a question: “So what if every Coke came with a few e xtra minutes of happiness?”Few American companies have worked as hard as Coca-Cola to associate themselves with pleasure. One of the company‟s first advertising slogans, in 1905, was “Coca-Cola Revives and Sustains.” The most obvious aesthetic forbear for the “Hello Happiness” ad is perhaps the iconic 1971 ad “I‟d Like to Buy the World a Coke,” for which Coke gathered hundreds of teenagers of various ethnicities on a hillside in Italy, at the height of the Cold War, to sing an anthem about bringing harmony to the world by—what else?—serving it a carbonated beverage. “That was the basic idea: to see Coke not as it was originally designed to be—a liquid refresher—but as a tiny bit of commonality between all peoples, a universally liked formula that would help to keep them company for a few minutes,” Bill Backer, who was at the time the creative director on the Coca-Cola account for McCann-Erickson, wrote.More than four decades later, Coke‟s message remains more or less the same. But the company‟s audience has grown considerably. Coca-Cola has sold soft drinks abroad for decades—for so long that the brand has become one of the most enduring symbols of American capitalism. But its sales are slowing in the U.S. and other Western countries, which has Coca-Cola executives increasingly looking elsewhere for new customers. To that end, the company is spending more on advertising in developing regions where people aren‟t already drinking a lot of Coke.Coca-Cola isn‟t the only one interested in happiness. So are researchers and policymakers who want to measure global development in terms that go beyond economic models. In recent years, some of them have come up with several factors that tend to contribute most to over-all happiness. They include having a higher income, belonging to a community, being in good health, and feeling satisfied with work. Coca-Cola isn‟t on the list. Sometimes a soda, refreshing as it may be, is just a soda.1. According to Bill Backer, Coca-Cola represents all of the following aspects EXCEPT.A. people‟s similaritiesB. enjoyed timeC. connecting relationshipsD. common flavor2. It is implied that the connotation Coca-Cola conveys .A. has changedB. has stabilizedC. has upgradedD. has degraded3. Advertisements are used to .A. explore the new marketB. increase the saleC. develop unknown areasD. promote the product4. We can conclude from the last paragraph that .A. the interrelationship between Coca-Cola and happiness is groundless and absurdB. many people are interested in the interrelatedness between Coca-Cola and happinessC. more than one factor have something to do with happinessD. people in different occupations have different views on what leads to happiness5. The author‟s attitude towards the correlation between Coca-Cola and happiness seems to be .A. uncertainB. certainC. pessimisticD. optimistic。
