Communication is a part of our everyday life. Humans are social beings and we need to live with other people. When we communicate, we can make use of both spoken and written language. But are they enough？The answer is NO. Sometimes we have to communicate by using body movements instead of words. This is called body language.

　　Body language is very important in our lives for several reasons.

　　Firstly, it makes our communication more colourful. It's really hard to imagine a conversation without any body language involved. How dull and boring it will be to just talk without any gestures，facial expressions or any other body movements！Body language makes our talking more lively and interesting.

　　Secondly, it makes our communication more effective. Sometimes a gesture or a facial expression can make us more easily and quickly understood. Take a good speaker for example：his or her body movements will help him or her leave a deeper and stronger impression (印象) on listeners.

　　Finally, sometimes we have to use body language. On some occasions (场合), we are not allowed to speak loudly. Examples of this are in the library or in the quiet classroom. Then body language will be quite necessary. Also, when we meet someone in the street, there is no need for us to stop for a long chat, so a nod or a wave may be OK.

　　Maybe ten­year­old Elizabeth put it best when she said to her father, "But, Dad, you can't be healthy if you're dead." Dad, in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt - a mistake 75% of the US population makes every day. The big question is why.

　　There have been many myths about safety belts ever since their first appearance in cars some forty years ago. The following are three of the most common.

　　Myth Number One: It's best to be "thrown clear" of a serious accident.

Truth：Sorry, but any accident serious enough to "throw you clear" is also going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield (挡风玻璃) or door to do it. Studies show that chances of dying after a car accident are twenty five
