The regular responds to each greeting, usually addressing the greeter by name or nickname (“Evening, Doe”, “Al, there, Lofty?” “Wotcha, Bill” “Usual, thanks, Pauline”, etc.). No one is conscious of obeying a rule or following a formula, yet you will hear the same greeting ritual in every pub in the country.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/Pub etiquette does not limit the actual words to be used in this exchange—and you may hear some inventive and peculiar variations. The words may not even be particularly polite: a regular may be greeted with “Back again, Joe?—haven’t you got a home to go to?” or “Ah, just in time to buy your round, Joe!”
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/B) When you first enter a pub, don’t just order a drink—start by saying “Good evening” or “Good morning”, with a friendly nod and a smile, to the bar staff and the regulars at the bar counter. For most natives, this will start an automatic greeting-response, even if it is only a nod. Don’t worry if the initial response is somewhat reserved. By greeting before ordering, you have communicated friendly intentions. Although this does not make you an “instant regular”, it will be noticed, and your subsequent attempts to initiate contact will be received more favorably.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/C) You may well hear a lot of arguments in pubs—arguing is the most popular pastime of regular pub-goers—and some may seem to be quite heated. But pub-arguments are not like arguments in the real word. They are conducted in accordance with a strict code of etiquette: You should not take things too seriously. The etiquette of pub-arguments reflects the principles governing all social interaction in the pub: equality, interaction, the pursuit of intimacy and a non-aggression agreement. Any student of human relations will recognize these principles as the essential foundation of all social bonding, and social bonding is what pub-arguments are all about. Rule number one: The pub-argument is an enjoyable game—no strong views or deeply held convictions are necessary to engage in a lively dispute. Pub regulars will often start an argument about anything, just for the fun of it.
D) A bored regular will often deliberately spark off an argument by making an outrageous or extreme statement, and then sit back and wait for the inevitable cries of “Rubbish!”—or something less polite. The initiator will then hotly defend his statements (which he secretly knows to be indefensible), and counter-attack by accusing his opponents of stupidity, ignorance or worse. The exchange may continue in this fashion for some time, although the attacks and counter-attacks will often drift away from the original issue, moving on to other contentious subjects and eventually focusing almost entirely on the personal qualities of the participants. You may notice, however, that opponents continue to buy each other drinks throughout the match. By the end, everyone may have forgotten what the argument was supposed to be about. No-one ever wins, no-one ever surrenders. When participants become bored or tired, the accepted formula for ending the argument is to finish a sentence with “—and anyway, it’s your round”. Opponents remain the best of mates, and a good time has been had by all.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/E) Do not try to join in arguments taking place at tables: only those which occur at the bar counter are “public” arguments. Even at the bar counter, watch for the “open” body-language which signals that others are welcome to participate. Involvement of the bar staff or publican is another sign that the argument is public rather than personal. Body-language and facial expressions are also your best guide to the level of “seriousness” of the dispute. Heated and even insulting words may be used, but in most pub-arguments the relaxed posture and expressions of the participants reveal the lack of any real hostility. Once you have established that the argument is both public and non-hostile, feel free to add your comments and opinions—but remember that this is a game, and do not expect to be taken seriously. Also remember that round-buying is the most effective non-aggression signal. If you unknowingly cause offence, or find yourself in any trouble, buy a round of drinks for your companions. The phrase “I think it must be my round” should get you out of almost any difficulty.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/F) Listen carefully, and you will realize that most pub-talk is also a form of free-association. In the pub, the naturally reserved and cautious natives give voice to whatever passing thought happens to occur to them. You will notice that pub-conversations rarely progress in any kind of logical manner; they do not stick to the point, nor do they reach a conclusion. Pub-talk moves in a mysterious way—mostly in apparently random sideways leaps.’ A remark about the weather starts a prediction as to which horse will win the big race at Cheltenham, which starts an argument about the merits of the National Lottery, which leads to a discussion of the latest political scandal, which is interrupted by another regular demanding assistance with a crossword clue, one element of which leads to a comment about a recent fatal traffic accident in the neighborhood, which somehow turns into a discussion about the barman’s new haircut and so on. There is a vague logic in some of the connections, but most changes of subject are started by participants “free-associating” with a random word or phrase.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/G) Having established that the conversation is “public” (taking place at the bar counter, open body-language, etc.), you just say whatever happens to come into your head in connection with the current topic of conversation.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/Jokes, puns, teasing, wit, and backchat (回嘴) are all essential ingredients of pub-talk. In fact, you will notice that most pub-talk has an undercurrent of humor, never far below the surface.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/Most pub humor is quite subtle—occasionally to the point of obscurity—and some participants have a command of irony that would impress Jane Austen.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/Rule number two: Be prepared to laugh at yourself, as you will almost certainly be teased.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/H) Like Austen’s Mr. Bennet, pub regulars are disposed to find the faults and mistakes of others amusing, rather than distressing. A boastful person will often be encouraged to explain his favorite topic (“Oh, did you really? Do tell us about it!”) purely so that the audience may laugh at his self-importance. If you are inclined to take yourself a bit too seriously, to mention your high-powered job more often than is strictly necessary, or to derive too much enjoyment from the sound of your own voice—beware! Any over-obvious attempts to impress the natives will have the opposite effect. But if you are teased about your failings, do not be upset or offended. Teasing is a sign that you are liked, in spite of your faults. Among regulars, everyone is subjected to at least some teasing—even the most kind and popular person will be found to have some quality worth laughing at. If the natives did not like you, they would not tease you, but would simply ignore and avoid you.
style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/ style=margin: 0px; padding: 0px; color: rgb(51, 51, 51); font-family: 宋体; font-size: 14px; white-space: normal; background-color: rgb(255, 255, 255);/I) As a newcomer, it is best to show that you can laugh at yourself before making fun of your new acquaintances. You may not be able to match the dry wit and quick response of native pub-goers, but as a foreigner, you do have two advantages. First, British pub-goers tend to regard all foreigners as instinctively funny. If you are prepared to laugh at yourself, all of your apparent disadvantages such as language difficulties, unfamiliarity with native customs, ignorance about British beer etc. are potential sources of amusement. Second, regulars may well be bored with each other’s familiar jokes, and will welcome any fresh material you can offer.

1.[选词填空]When pub regulars greet each other, they often give friendly greetings.

2.[选词填空]When free-association is involved, pub talks may rarely evolve logically.

3.[选词填空]The etiquette of pub-arguments is that pub-goers should not take things too seriously.

4.[选词填空]When a pub staff takes part in a pub-argument, it suggests that the argument is public.

5.[选词填空]You can begin to talk in free-association after you are sure that the conversation is public.

6.[选词填空]The etiquette of pub-arguments reflects principles of equality, interaction, the pursuit of intimacy and a non-aggression agreement.

7.[选词填空]It is necessary for someone who first enters a pub to greet before ordering because it will make his future contact easier.

8.[选词填空]Pub etiquette focuses mainly on the form of the conversation.

9.[选词填空]If the other pub regulars make fun of you, it indicates that they like you.

10.[选词填空]All of your obvious disadvantages as a foreigner will become sources of amusement when you are prepared to laugh at yourself.

     The picnics,speeches,and parades of today’s Labor Day were all part of the first celebration,held in New York City in 1882. Its promoter was an Irish-American labor leader named Peter J. McGuire, a carpenter by trade. McGuire had worked since the age of eleven and in 1882 was president of the United Brotherhood of Carpenters and Joiners(UBCJ). Approaching the City’s Central Labor Union that summer,he proposed a holiday that would applaud(赞许)“the industrial spirit-the great vital force of every nation”. on September 5,his suggestion bore fruit,as an estimated 10,000 workers,many of them ignoring their bosses’warnings,left work to march from Union square up Fifth Avenue to 42nd Street. The event gained national attention,and by 1893 thirty states had made Labor Day an annual holiday. 
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/     The quick adoption of the scheme may have indicated less about the state lawmaker’s respect for working people than about a fear of risking their anger. In the 1880s the United States was a land sharply divided between the immensely wealthy and the very poor. Henry George was accurate in describing the era as one of“progress and poverty”. In a society in which factory owners rode in private Pullmans while ten-year-olds slaved in the mines,strong anti-capitalist feelings ran high. Demands for fundamental change were common throughout the labor press. With socialists demanding an end to“wage slavery" and anarchists(无政府主义)singing the praises of the virtues of dynamite(炸药),middle-of-the-roader slike Samuel Gompers and McGuire seemed attractively mild by comparison. One can imagine practical capitalists seeing Labor Day as a bargain:A one-day party certainly cost them less than paying their workers decent wages.

    A theme is emerging from the flood of recent corporate earnings reports: cost cuts are boosting profits. Investors are cheering, but they shouldn't. Even in these tough times, more CEOs should be talking about how they are seeking out investments, developing new technologies and making acquisitions.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/That's what will set their companies up fora stronger future. Intel Corp.'s former CEO Gordon Moore had it when he said years ago that "you can't save your way out of a recession." He meant that even in the toughest times, companies have to spend money on new ideas.Recessions always end, Moore often said, and when they do, companies that embraced innovation (创新)during the downturn won't be stuck with obsolete products and services. Instead, they'll have new things to offer' once demand picks up again.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    "Customers don't come out of recessions spending the way they did before," said Chunka Mui, who has studied how companies can capitalise on opportunities during crises at his Chicago-based consulting firm, The Devil's Advocate Group. "They demand something different."
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    Surprisingly few companies are following Moore's advice of innovating during recessions. Many have been weakened by the pullback in consumer and business spending as well as tight credit conditions,which is making it harder for companies to get loans to fund their operations. That's driven some to hold cash and make drastic cost cuts. They're slashing (大幅度削减)jobs and wages and closing stores and factories.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    The aggressive cuts have allowed companies to exceed Wall Street's expectations for their earnings. In fact, the"good" news has sent the Dow Jones industrial average above 10,000 for the first time in a year. The problem is that too many companies are making widespread, not focused cuts. They're telling every division to cut 10 percent of their work force or slashing marketing dollars by the same amount companywide.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    "That is a quick way to rid a company of costs. But it doesn't help it get in a better position going forward",says Cesare Mainardi, managing director at the consulting firm Booz & Co.and coauthor of the new book Cut Costs, Grow Stronger, "and a downturn like this should force people's hand".

    Single-sex education is the practice of conducting education where male and female students attend separate classes in separate schools. The practice was predominant (突出的) before the midtwentieth century, particularly in secondary education and higher education. Single-sex education is often advocated on the basis of tradition,as well as religious or cultural values. It is practiced in many parts of the world.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    A number of studies starting in the 1990s are showing statistical data that children from single-sex schools are outperforming students from coeducational (男女同校的) schools,although some studies also say that these are non-conclusive. In 2002, because of these studies and bipartisan (两党的) support, the US law of 1972 that made coeducation in public schools mandatory was revoked and funding was given in support of the single-sex option. There are now associations of parents who are advocating for single-sex education.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/In some cases, parents are now making the decision to send their child to a single-sex schools for the following reasons.The first one is the teacher-student ratios are typically much higher in the single-sex schools because in most single-sex schools there are smaller class sizes. Secondly, parents and students are often choosing a single-sex learning environment because they think with good reason that their child or themselves will receive a better education. International research has shown that boys and girls perform best when they are taught separately in their teen years.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    Critics of the single-sex education argue that segregated learning facilities are inherently unequal. System bias will reinforce gender stereotypes and perpetuate societal inequalities in opportunities afforded to males and females. Single-sex schools in fact accentuate (使……突出) gender-based educational limitations and discrimination. Boy's schools may not offer home economics classes, while girl's schools may not offer metalwork, woodwork or as wide a variety of sports.
style=color: rgb(51, 51, 51); font-family: "Microsoft YaHei"; white-space: normal; background-color: rgb(250, 250, 250);/    Some children like larger classrooms. These larger classrooms give them more competition and can even make some students more motivated to work harder. When there are more children in a class people may think children can get lost, but some students think of it as something that pushes them to work harder. Although this statement is the opposite of a single-sex school advantage that was listed above, this is just further proof that it all depends on each child and that each children quires a learning environment best for her/him.

1.[单选题]Which of the following is held by the opponents of the single-sex education?

A.Students in each class in most single-sex schools are fewer.

B.Students in a single-sex school can't broaden their horizons.

C.Students perform badly by learning separately in their teen years.

D.Segregated learning will further deepen gender discrimination.

3.[单选题]The author's attitude towards the single-sex education is __.

A.positive

B.subjective

A.It segregates males and females in the same school.

B.It began from the mid-twentieth century.

C.It was once overwhelming in secondary education and higher education.
