优翼小帮手同步口算系列答案We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. This article gives some suggestions on how to give an effective speech.
So, you have to give a speech—and you are terrified. You get nervous, you forget what you want to say, you stumble over words, you talk too long, and you bore your audience. Later you think, “Thank Goodness, it’s over. I’m just not good at public speaking. I hope I never have to do that again.”
Cheep up! It doesn’t have to be that bad. Here are some simple steps to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion? Why are you speaking? Then, gather as many facts as you can on your subject. Spend plenty of your time doing your research. Then spend plenty of your time organizing your material so that your speech is clear and easy to follow. Use as many examples as possible, and use pictures, charts, and graphs if they help you make your points more clearly. Never forget your audience. Don’t talk over their heads, and don’t talk down to them. Treat your audience with res
pect. They will appreciate your thoughtfulness.
Just remember: Be prepared. Know your subject, your audience, and the occasion. Be brief. Say what you have to say and then stop. And be yourself. Let your personality come through so that you make person-to-person contact with your audience.
If you follow these simple steps, you will see that you don’t have to be afraid of public speaking. In fact, you may find the experience so enjoyable that you volunteer to 
make more speeches! You’re not convinced yet? Give it a try and see what happens.

A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.
Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.
Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack（缺乏）of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on （补充）sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes（糖尿病）. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.
