单选题 Linguistics professors and therapists have discovered how people achieve mutual understanding, both consciously and unconsciously, by observing the body language and voice patterns of the person they are talking to. If you are dealing with someone who is painfully shy, you're not going to make a good connection by overwhelming them with your cheerfulness. By matching someone's behavior we can gain their confidence, achieve a good relationship and improve the quality of communication—in other words, we can get on someone's wavelength. One of the powerful aspects of Neuro-Linguistic Programming (NLP) is its use of suggestion and positive thinking. We can become aware of the negative and turn it to the positive. Once it is framed in a positive way as a goal, the brain can begin to grapple with it and then apply itself to achieving that outcome. To put it another way, if you don't know where you're going, it makes it harder to get there. "I wish I weren't so shy" is no good as a goal. "I want to be confident, relaxed and outgoing when I meet new people" tells you’ exactly what you want and gives you some clues as to how you could modify your behavior to achieve it. At some level we already know this. What's the best way to make someone, particularly a child, drop something? Say " Mind you don't drop it. " If you tell children "Don't make a mess", a mess is undoubtedly what they will make. You have announced your expectations. You've already visualized the tray being dropped, the room being untidy and, surprise, the wheels are set in motion and what we warn against is what happens. So, avoid making negative statements. Instead, try saying "Could you please keep the room tidy?" or "Make sure you keep those drinks on the tray. " Immediately, you have a more positive image of the desired outcome of events and your brain and body become subconsciously programmed to achieve it. NLP can be applied to any area of human activity. It has been used to cultivate excellence in sport, business, education, music and the arts. Managers find their managerial skills improved, salespeople learn how to adapt their presentation to the customer, and educators find ways to involve students more fully.

单选题The most exciting kind of education is also the most personal. Nothing can exceed the joy of discovering for yourself something that is important to you! it may be an idea or a bit of information you come across accidentally—or a sudden insight, fitting together pieces of information or working through a problem. Such personal encounters are the "payoff" in education. A teacher may direct you to learning and even encourage you in it—but no teacher can make the excitement or the joy happen. That's up to you. A research paper, assigned in a course and perhaps checked at various stages by an instructor, leads you beyond classrooms, beyond the texts for classes and into a process where the joy of discovery and learning can come to you many times. Preparing the research paper is an active and individual process, and ideal learning process. It provides a structure within which you can make exciting discoveries of knowledge and of self, which are basic to education. But the research paper also gives you a chance to individualize a school assignment, to suit a piece of work to your own interests and abilities, to show others what you can do. Writing a research paper is more than just a classroom exercise. It is an experience in searching out, understanding and composing, which forms the basis of many skills applicable to both academic and nonacademic tasks. It is, in the fullest sense, a discovering, an education. So, to produce a good research paper is both a useful and a thoroughly satisfying experience! To some, the thought of having to write an assigned number of pages, often more than ever produced before, is disconcerting. To others, the very idea of having to work independently is threatening. But these is no need to approach the research paper assignment with anxiety, and nobody should view the research paper as an obstacle to overcome. Instead, consider it a goal to accomplish, a goal within reach if you use the help this book can give you.
