单选题If you left your book on the table overnight, you would find the following morning that it was still exactly where you had left it, provided nobody had moved it. If a ball is made to roll on a very smooth surface, it will roll a long distance unless something stops it or changes its direction. This tendency of an object to remain at rest unless something moves it and to continue moving unless something stops it is known as the Law of Inertia. The following examples show the truth of this law. a. Put a table-cloth on a table and arrange a pile of books on it. Hold one edge of the table-cloth and pull it quickly. The table-cloth will come off, leaving the pile of books undisturbed. b. Place a small piece of cardboard on an open jar and place a coin on it directly over its mouth. Use one finger to flick the piece of cardboard away. You will notice that the coin drops into the jar. c. Sitting in a car which starts suddenly, you feel you are jerked backwards. In fact, you are not jerked backwards. Your lower half, which is in contact with the cushion, is forced to move forward with the car, and the upper part of your body, which remained at rest, is left behind.

单选题 A large part of effective leadership is dependent on something called "style". But style is difficult to teach, and what makes one leader great and another mediocre is not easily defined. Leadership always implies power, and a broad definition in this {{U}}context{{/U}} is that leadership includes the power to influence thoughts and actions of others in such a way that they achieve higher satisfaction and/or performance. Over the past century, there have been three major approaches to understanding leadership. Identifying leadership traits, or the physical and psychological characteristics of leaders, was the first formal approach, and had a lot of intuitive appeal. It owed its origins to the mm of the century (about 1904) when trait studies began. At this time most American leaders came from certain wealthy families, the vast majority were white males, and there were some social {{U}}norms{{/U}} about what leaders looked like (tall, square jaw, well groomed, etc.). The original assumption that "leaders are born, not made" has been discredited, because there were too many exceptions to the traits to give {{U}}them{{/U}} any credibility. Beginning after World War II, in sharp contrast to the trait approach, the behavioral approach looked at what a leader does, what behaviors leaders use that set them apart from others. This approach assumed that leadership could be learned. Virtually all of the studies focused on classifying behaviors according to whether they fell into a process or "people approach" (satisfying individual needs), or a "task approach" (getting the job done). The basis for this classification was in the discovery in social psychology that every group needs someone to fulfill both these roles in the group for it to be effective. The earliest of these studies began in Ohio State University and the University of Michigan in the late 1940s. Many of the early trait and behavioral writers tried to make their ideas applicable to all leadership situations. The earliest situational approach to leadership was developed in 1958. This approach {{U}}strived{{/U}} to identify characteristics of the situation that allowed one leader to be effective where another was not. The trend later developed toward the third approach, understanding the unique characteristics of a situation and what kind of leadership style best matches with these.

单选题The Lagoon Show 礁糊秀 The most romantic time to arrive in Venice is at dusk on a winter's day. Your water-taxi ride across the lagoon from the airport will catch the last velvety-grey streaks of daylight. You'll arrive on the Grand Canal just as the upper windows of its palaces start to bloom with rose-coloured lamps or sparkle with chandeliers. In no other city does evening begin with such promise. Strange, then, that Venice should be so emphatically not a night-time place. However mobbed it may have been in daylight, darkness falls with the abruptness of a hauled-down shutter. The crowds of Asian tourists and schoolkits milling around seem to vaporize. In a hundred closed cafes, the espresso machines give an expiring hiss, as if at last slipping off their shoes and wiggling their toes. That is what makes Venice by night so magical, when the loudest sounds are those of footsteps and lapping water, and the modern world recedes so that in any Square or over any bridge, you wouldn't be surprised to meet a hurrying figure in a cloak and buckled shoes; Casanova on his way to some assignation, perhaps. St. Mark's becomes an enchanted place, with pools of the day's flood still underfoot and mist wreathing the cathedral. But "nightlife" seems nonexistent outside the weeks of carnival each February. In a city so stuffed with historical treasures, the lack of a living, modern culture is achingly apparent, especially after dark. Venice's only theatre of note, the Fenice, has only just reopened after almost a decade, following a fire. Clubs, discos, even cinemas are almost as hard to find as car parks. Nor is there the eating-out culture that governs the rest of Italy. Venice is not usually regarded as a gourmet paradise. Even J G Links, author of the definitive, eccentric guidebook Venice for Pleasure, suggests it has few restaurants worth visiting outside the Cipriani hotel. As a rule, it's best to avoid canalside establishments with their menus turisticos; look for places down alleys. Remember, this is rice, not pasta country, offering some of the best risotto you're ever likely to eat. When I first came here, aged 15, on a school trip, we were quartered in a girl's convent school. Ever since, I've stayed at the Gritti Palace, on the Grand Canal, overlooking the Salute. Apart from its mixture of elegance and old-fashioned comfort, I have two reasons for loving this hotel. Alighting at its private landing stage completes the thrill of arriving in Venice by night. And it was here, 13 years ago, that Sue and I decided to get married and have our daughter. Gondolas operate until well after dark. It can be doubly romantic, with the Grand Canal in pitch-darkness and silent but for the churn of water buses and scraps of operatic arias that some gondoliers still perform. Latterly, Venice has been making more efforts to get a nightlife. There is a disco named Casanova near the railway station and a music bar, Piccolo Mondo, near the Accademia bridge. The city's student population has created funkier areas around Campo Santa Margarita and in Cannaregio, the immigrant quarter to the north. There is also street music after all the smart shops have closed and the only merchandise on offer is fake designer handbags, set out on the trestles used as walkways at times of flooD．Around one corner, you may come upon a countertenor in an anourak, singing Handel; around another, two men will be playing selections from Andrew Lloyd Webber on a vibraphone of water-filled glasses. You think that sounds totally naff? I can tell you it sounded totally wonderful. Such is the alchemy of Venice by night.
