Climate, more than any other single factor, 11 the distribution of life on Earth. Climatic boundaries establish the limits within which organisms can survive. Plants, even more than animals,must be 12 adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to 13 whatever weather conditions are likely to occur. In the harsh conditions ofthe far north of the earth, for example, low growing mosses, lichens, and a few flowering plants all hold to the ground for shelter from icy winds.
Animals, despite their 14 to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that theyhave an 15 limited distribution. Others, such as bears, are flexible enough to adapt to a 16 range of climates.. Ocean-dwelling organisms are just as sensitive to climatic changes—in this casetemperature and salinity—as land animals. Reef corals can survive only in clear warm seawater. Certain foraminaters are so sensitive to changes in their 17 that their presence can be taken asan 18 of sea temperature. Human beings are among the 19 specialized of all animals and can live almost anywhere. Their clothes and their homes 20 as a sort of "miniature climate" that can betaken with them everywhere.

Once you're prepared for a situation, you're 50 percent of the way toward overcoming nervousness. The other 50 percent is the physical and mental control of nervousness; adjusting yourattitude so you have confidence, and control of yourself and your audience.
I was in the theater for many years and always went to work with terrible stage fright—until I was in "The King and I". While waiting offstage one night, I saw Yul Brynner, the show's star,pushing in a lunging position against a wall. It looked as though he wanted to knock it down. "This helps me control my nervousness," he explained.
I tried it and, sure enough, freed myself from stage fright. Not only that, but pushing the wall seemed to give me a whole new kind of physical energy. Later I discovered that when you pushagainst a wall you contract the muscles that lie just below where your ribs begin to splay 展开. I call this area the "vital triangle".
To understand how these muscles work, try this: sit in a straight-backed chair and lean slightly forward. Put your palms together in front of you, your elbows pointing out the sides, yourfingertips pointing upward, and push so that you feel pressure in the heels of your palms and under your arms.
Say ssssssss, like a hiss. As you're exhaling the s, contract those muscles in the vital triangle as though you were rowing a boat, pulling the oars back and up. The vital triangle shouldtighten. Relax the muscles at the end of your exhalation, then inhale gently.
You can also adjust your attitude to prevent nervousness. What you say to yourself sends a message to your audience. If you tell yourself you're afraid, that's the message your listenerreceives. So select the attitude you want to communicate. Attitude adjusting is your mental suit of armor against nervousness. If you entertain only positive thoughts, you will be giving outthese words: joy and ease, enthusiasm, sincerity and concern, and authority.
