    Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $ 16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip.

    But according to a new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service.

    Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least 15% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $ 2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping. According to Michael Lynn, the Cornell papers' author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, “In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off.”

阅读甲、乙两部分文字,完成1——4题。

【甲】臣本布衣,躬耕于南阳,苟全性命于乱世,不求闻达于诸侯。先帝不以臣卑鄙,猥自枉屈,三顾臣于草庐之中,咨臣以当世之事,由是感激,遂许先帝以驱驰。后值倾覆,受任于败军之际,奉命于危难之间,尔来二十有一年矣。

 (诸葛亮《出师表》节选)

【乙】信①数与萧何②语,何奇之。至南郑,诸将行道亡者数十人,信度何等已数言上③,上不我用,即亡。何闻信亡,不及以闻,自追之。人有言上曰:“丞相何亡。”上大怒,如失左右手。居一二日,何来谒上,上且怒且喜,骂何曰:“若亡,何也?”何曰:“臣不敢亡也,臣追亡者。”上曰:“若所追者谁何?”曰:“韩信也。”上复骂曰:“诸将亡者以十数,公无所追;追信,诈也。”何曰:“诸将易得耳。至如信者,国士无双。”……王曰:“吾为公以为将。”何曰:“虽为将,信必不留。”王曰:“以为大将。”何曰:“幸甚。”于是王欲召信拜之。何曰:“王素慢无礼,今拜大将如呼小儿耳,此乃信所以去也。王必欲拜之,择良日,斋戒,设坛场,具礼,乃可耳。”王许之。诸将皆喜,人人各自以为得大将。至拜大将,乃韩信也,一军皆惊。

注释①信:韩信。②萧何:刘邦的丞相。③上:帝王,这里指刘邦。
