At a party, it is quite normal of someone to have a short conversation with you and then go

on to talking with other people! Don't think they dislike you and that they are impolite. It was

the custom at many parties in Britain, particularly there people are standing up rather than

sitting down. Here are ways of finishing conversation at a party. "Excuse me. I think I'll go and

get another drinking. See you later." "Oh. Excuse me. I've just seen Mary Jennings over here.

I've got to discuss a meeting we are having in Thursday. Would you excuse me and for a

moment?"

Maybe ten-year-old 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 US population make every day. The big question is why.

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

 Myth the 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 able going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield (擋風玻璃)or door to do it. Studies show that chances of dying after a car accident are twenty-five times in cases where people are "thrown clear".

 Myth Number Two: Safety-bets "trap" people in cars that are burning or sinking in water.

    Truth: Sorry again, but studies show that people knocked unconscious (昏迷) due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situation, not to be trapped in them.

 Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour (mph).

 Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 metres.

 A. He was driving at great speed.

B. He was running across the street.

C. He didn't have his safety belt on.

A. wasn't feeling very well     B. hated to drive in the dark

C. wanted to take some exercise  D. didn't want to be caught by the people

A. may be knocked down by other cars.

B. may get serious hurt thrown out of the car

C. may find it impossible to get away from the seat

 D. may get caught in the car door

Some people prefer to drive without wearing a safety belt because they believe _______.

A. the belt prevents them from escaping in an accident

B. they will be unable to think clearly in an accident

C. they will be caught when help comes

 D. cars catch fire easily
