单选题 The first time your boss suggests that you formally present something to your department or a client, your reaction may be panic. But remember that being asked to present is a compliment. Someone believes that you have valuable information to share with the group, and wants to listen to your ideas. You need to decide exactly what you will say during the allotted time. Condense your topic into one sentence. What do you want your audience to remember or learn from your talk? This is your 'big idea'. Remember that your are dealing with the short attention spans of individuals who tend to have many things on their minds. Think of three main points you want to make to support your overall topic. Develop a story to demonstrate each of those concepts. This could be something that happened to you or someone you know, or something you read in a newspaper or magazine. We have all heard the saying 'A picture is worth a thousand words.' Think about how your presentation can be more interesting to watch. Props are a wonderful way to make your talk come alive. You could do something as simple as holding up a toy phone receiver when talking about customer service or putting on a hat to signal a different part of your talk. Think of dynamic and unusual way to start your presentation. This might involve telling anecdotes that relate to your topic. Never begin with, 'Thank you for inviting me here to talk with you today.' You will put your audience to sleep right away. Start off enthusiastically so they will listen with curiosity and interest. After your energetic introduction, identify yourself briefly and thank the audience for taking the time to listen to you. Plan your ending, and finish in a memorable way. Your listeners remember best what they hear at the beginning and end of a speech, so conclude with a game in which they can participate, or tell a humorous story and your audience will leave laughing. Don't try to memories your talk or read it word-for-word. It will sound stilted and boring. Instead, practice your dynamic introduction and conclusion until you can deliver them effortlessly. If you do this you'll feel a burst of confidence that will help you sail through the whole of the speech.

单选题Many people believe the glare from snow causes snow blindness. Yet, dark glasses or not they find themselves suffering from headaches and watering eyes, and even snowblindness, when exposed to several hours of "snow light". The United States Army has now determined that the glare from snow does not cause snow-blindness in troops in a snow-covered country. Rather, a man's eyes frequently find nothing to focus on in a broad expanse of a snow-covered area. So his gaze continually shifts and jumps back and forth over the entire landscape in search of something to look at. Finding nothing, hour after hour, the eyes never stop searching and the eyeballs become sore and the eye muscle aches. Nature balances this annoyance by producing more and more liquid which covers the eyeballs. The liquid covers the eyeballs in increasing quantity until vision blurs. And the result is total, even though temporary, snowblindness. Experiments led the Army to a simple method of overcoming this problem. Scouts ahead of a main body of troops are trained to shake snow from evergreen bushes, creating a dotted line as they cross completely snow-covered landscape. Even the scouts themselves throw lightweight, dark-colored objects ahead on which they too can focus. The men following can then see something. Their gaze is arrested. Their eyes focus on a bush and having found something to see, stop searching through the snow-blanketed landscape. By focusing their attention on one object at a time, the man can cross the snow without becoming hopelessly snowblind or lost. In this way the problem of crossing a solid white area is overcome.
