| 第5题：Passage 10 In recent years, Israeli consumers have grown more demanding as they’ve become wealthier and more worldly-wise. Foreign travel is a national passion; this summer alone, one in 10 citizens will go abroaD、Exposed to higher standards of service else where, Israelis are returning home expecting the same.American firms have also begun arriving in large numbers.Chains such as KFC, McDonald’s and Pizza Hut are setting a new standard of customer service, using strict employee training and constant monitoring to ensure the friendliness of frontline staff.Even theAmerican habit of telling departing customers to "Have a nice day" has caught on all over Israel. "Nobody wakes up in the morning and says, ’Let’s be nicer,’" says ItsikCohen, director of a consulting firm. "Nothing happens without competition." Privatization, or the threat of it, is a motivation as well. Monopolies that until recently have been free to take their customers for granted now fear what Michael Perry, a marketing professor, calls "the revengeful (报复的) consumer". When the government opened up competition withBezaq, the phone company, its international branch lost 40% of its market share, even while offering competitive rates. Says Perry, "People wanted revenge for all the years of bad service." The electric company, whose monopoly may be short-lived, has suddenly stopped requiring users to wait half a day for a repairman. Now, appointments are scheduled to the half-hour. The gracelessE1A1Airlines, which is already at auction, has retrained its employees to emphasize service and is boasting about the results in an ad campaign with the slogan, "You can feel the change in the air." For the first time, praise outnumbers complaints on customer survey sheets. In the author’s view, higher service standards are impossible in Israel A、if customer complaints go unnoticed by the management. B、unless foreign companies are introduced in greater numbers. C、if there’s no competition among companies. D、without strict routine training of employees. |

| 第10题：在西湖的野鸭群中雄性和雌性的比例是55：45，而在东湖的野鸭群中雄性和雌性的比例则是65：35。在尚未有生育能力的野鸭子中，雄性只略多于雌性，但是在较年长的野鸭子中，雄性却远多于雌性。由于成年的雄鸭远多于未成年的雄鸭，所以，在总体上性别比例的差距越大，野鸭群中较年长的雄鸭所占的比例就越大。 以下哪项能从上文中推出
A．西湖鸭群中成年雄鸭的比例小于东湖鸭群中成年雄鸭的比例。 B．东湖鸭群中未成年野鸭的比例高于西湖野鸭群中未成年野鸭的比例。 C．东湖野鸭群中雄野鸭的总数多于西湖鸭群中雄野鸭的总数。 D．东湖鸭群中在生育季节生出的未成年鸭子数量多于西湖中在生育季节生出的未成年鸭子数量。 E．东湖鸭群中成年雌野鸭的数量多于未成年的雌野鸭的数量。 |
