单选题It is hard to imagine a more perfect gift than a fine watch, which lasts a lifetime and can become a family heirloom (传家宝). "Other gifts that you give don't last very long," says vice president Karl-Friedrich Scheufele of Geneva-based Chopard. "And there are very few that stay with the person wherever they go. This is the amazing thing about watches -- they are both beautiful and intimate. You have one on your wrist, and you remember a happy time in your life when you look at it." For something so personal, choosing the right watch demands corresponding care. Here is a brief look at some trends watch buyers will encounter this season. The most obvious trend in watches this season is the overwhelming popularity of sports watches in stainless steel. Yellow gold and two-tone watches of gold and steel are out -- and full steel is in. With the steel trend comes sportiness (花哨), which has been the industry's watchword, as it were, for the past three years. Generally speaking, the demand for large-scale steel-case designs -- with either steel or leather straps -- has led to a great supply of large, even bulky, designs for both men and women. "There is a demand for watches that are bigger and bolder," says Suryia Hill, media-relations manager for Roberg6 Watches Geneva. At Citizen, bulky sports watches are the big sellers. "People like to differentiate themselves with their watches, and calm, thin designs are not popular at the moment," says Willi Richter, general manager of Hamburg-based Citizen Watch Europe GmbH. "Young, middle-aged and even older people these days want to show that they are active, so they prefer bold, active watches./

单选题 Informal conversation is an important part of any business relationship. Before you start a discussion, however, make sure you understand which topics are suitable and which are considered taboos (禁忌) in a particular culture. Latin Americans enjoy sharing information about their local history, art, and customs. They expect questions about their family and are sure to show pictures of their children. Yon may feel flee to ask similar questions of your Latin American friends. The French think of conversation as an art form, and they enjoy the value of lively discussions as well as disagreements. For them, arguments can be interesting-and they can cover pretty much or any topic-as long as they occur in a respectful and intelligent (智慧的) manner. In the United States, business people like to discuss a wide range of topics, including opinions about work, family, hobbies, and politics. In Japan, China, and Korea, however, people are much more private. They do not share much about their thoughts, feelings, or emotions because they feel that doing so might take away from the harmonious (和谐的) business relationship they're trying to build. Middle Easterners are also private about their personal lives and family matters. It is considered rude, for example, to ask a businessman from Saudi Arabia about his wife or children. As general rule, it's best not to talk about politics or religion (宗教) with your business friends. This can get you into trouble, even in the United States, where people hold different views. In addition, discussing one's salary is usually considered unsuitable. Sports is typically a friendly subject in most parts of the world, although be careful not to criticize a national sport. Instead, be friendly and praise your host's team.

单选题In The Birth Order Book: Why You Are the Way You Are (2004), Dr. Kevin Leman notes that 21 of the first 23 Americans in space were first-born males or only children. More than half of United States presidents have been first-borns or first-born boys. It"s a pretty significant finding historically, because families used to be bigger than they are today. In addition to being high achievers, older children also generally have higher IQs (智商) than younger ones. Researchers have noted that the more kids a family has, the lower each child"s individual IQ tends to be. They give a few reasons for this. Parents only have so much time, attention, and money. The more kids they have, the more these things are divided. First-borns initially get the entire parental-time pie. What"s more, the ratio of grown-ups to kids decreases with each new baby. So the younger ones are surrounded by more children"s language on average than the older kids. Some researchers think parental attention is the key to personality birth-order differences. In his book Born to Rebel , psychologist Frank Sulloway says competition for Mom and Dad"s attention is the thing that really shapes our personalities and, in fact has shaped history. He argues that we adapt our personalities as part of our strategy to seek favor from Mom and Dad. Younger siblings (兄弟姐妹) tend to become rebels. Sulloway studied political activists and found that later-born activists were more radical than their first-born peers. The conclusion of his book is that sibling competition for parental attention can affect society as a whole in times of revolution. Thomas Jefferson, Karl Marx, and Fidel Castro were all younger siblings, for example. As compelling as this all is, it"s also something we should probably take with caution, there are other things that happen to us in life besides the addition of siblings to our families. A parent can die; a hurricane can leave us homeless; we can catch a life-threatening disease. Any one of these things will probably have more of an effect on our personalities than the presence of siblings. A 2002 study bore this out. After interviewing 535 undergraduates, researchers concluded that personality differences related to birth order were "folklore", although IQ and achievement differences were widely supported by research.
