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 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 travelled through a windshield 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 for 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 a speed of less than 30 miles per hour (mph).
Truth: When two cars travelling at 30 mph hit each other, an unbelted driver would meet the windshield with a force headfirst into the ground from a height of 10 meters.

听力原文： Why don't birds got lost on their long migratory flights？ Scientists have puzzled over this question for many years. Now they're beginning to fill in the blanks.
Not long ago, experiments showed that birds rely on the sun to guide them during daylight hours. But what about birds that fly mainly by night？ Tests with artificial stars have proved conclusively that certain night-flying birds are able to follow the stars in their long-distance flights.
One such bird—a warbler—had spent its lifetime in a cage and had never flown under a natural sky. Yet it showed an inborn ability to use the stars for guidance. The bird's cage was placed under an artificial star-filled sky at migration time. The bird tried to fly in the same direction as that taken by his outdoor cousins. Any change in the position of the make-believe stars caused a change in the direction of his flight.
Scientists think that warblers, when flying in daylight, use the sun for guidance. But the stars are apparently their principal means of navigation. What do they do when the stars are hidden by clouds？ Apparently, they find their way by such landmarks as mountain ranges, coast lines, and rivet courses. But when it's too dark to see these, the warblers circle helplessly, unable to get their bearings.
