Maybe ten-year-old Elizabeth put it when she said to 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 make every day.The big question is why.There have been many myths about safety belts ever since their first appearance in cars 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 travelled 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 times greater in cases where people are "thrown clear".Myth Number Two：Safety belts "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 a clear head to free themselves from such dangerous situations, 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 meters.1. Why did Elizabeth say to her father, "But, Dad, you can't be healthy if you're dead"? _____A. He was driving at great speed.B. He was running across the street.C. He didn't have his safety belt on.D. He didn't take his medicine on time.2. The reason Elizabeth's father was in a hurry to get home was that he _____.A. wasn't feeling very wellB. hated to drive in the darkC. wanted to take some exerciseD. didn't want to be caught by the police3. According to the text, to be "thrown clear" of a serious accident is very dangerous because you _____.A. may be knocked down by other carsB. may get seriously hurt going thrown out of the carC. may find it impossible to get away from the seatD. may get caught in the car door4. Some people prefer to drive without wearing a safety belt because they believe _____.A. the belt prevents them from escaping in an accidentB. they will be unable to think clearly in an accidentC. they will be caught when help comesD. cars catch fire easily5. What is the advice given in the text? _____A. Never drive faster than 30 miles an hour.B. Try your best to save yourself in a car accident.C. Never forget to wear the safety belt while driving.D. Drive slowly while you're not wearing a safety belt.

They also believe that many children won′t wear seat belts anyway andthat may damage the belts or use them as weapons to hurt other children.A new Research Council report on school bussafety suggests that there are alternate safety devices and procedures that maybe more effective and less expensive. For example, the study committeesuggested that raising seat backs four inches may have the same safetyeffectiveness as seat belts.The report sponsored by the Department ofTransportation at the request of Congress, reviews seat belts extensively whiletaking a broader look at safety in and around school buses.
