单选题 You know you should do it, other people do it all the time. Maybe you're already done it but it wasn't very satisfying, and you'd like to learn to do it better. I'm talking, of course, about having a business lunch. Don't feel embarrassed if you are uncomfortable with the idea of sitting over a grilled chicken breast, talking to a prospective client. Most inexperienced, overeager launchers believe the main purpose of a business lunch is to either (a) conduct business or (b) eat lunch, and they're unsure how to mix the two. Don't worry! Business lunches aren't about either business or lunch, they're about building relationships. One of my business rules is "People do business with people they like". Often, it's not products, prices, or the company that makes the sale—it's the person. Business lunches are the perfect time for you and your client, supplier, or employee to get to know each other as people. This helps establish common interests and makes working together easier. The single most important thing you can do at a business lunch—even more important than picking up the tab—is listening. You don't need a particular reason to ask someone to lunch, so don't wait until for a certain occasion or issue. Don't make it seem like lunch is going to be a sales call. Instead, try the straightforward approach. "We've been doing business together for almost a year. I'd like to take you to lunch and get to know you a little better. " Or a little less straightforward, "I'm often in your area, how about having lunch sometime?" Have the other person suggest a place to eat—"Is there a restaurant you've been wanting to try?" Or if you have a limited budget, you choose a nice mid-priced restaurant. For-get McDonald's. If you're thanking someone for an important order, take them to a really special, possibly new restaurant. If you did the inviting, you pick up the tab, even if your guest says, "I can put this on my company's credit card. " But don't have a scene arguing over the check. You can just say, "You can get the next one. " Some companies have policies that don't permit employees to be treated; in that case, split the tab.

单选题Watch a baby between six and nine months old, and you will observe the basic concepts of geometry being learned. Once the baby has mastered the idea that space is three-dimensional, it reaches out and begins grasping various kinds of objects. It is then, from perhaps nine to fifteen months, that the concepts of sets and numbers are formed. So far, so good. But now an ominous development takes place. The nerve fibers in the brain insulate themselves in such a way that the baby begins to hear sounds very precisely. Soon it picks up language, and it is then brought into direct communication with adults. From this point on, it is usually downhill all the way for mathematics, because the child now becomes exposed to all the nonsense words and beliefs of the community into which it has been so unfortunate as to have been born. Nature, having done very well by the child to this point, having permitted it the luxury of thinking for itself for eighteen months, now abandons it to the arbitrary conventions and beliefs of society. But at least the child knows something of geometry and numbers, and it will always retain some memory of the early halcyon days, no matter what vicissitudes it may suffer later on. The main reservoir of mathematical talent in any society is thus possessed by children who are about two years old, children who have just learned to speak fluently.
