Question

     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 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 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 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.

Answer 1

1----5  CCBAC     

解析:

1.这是一道句意理解题。从第二自然段第一句可知，他女儿说这句话的意思是他匆忙中没有系上安全带。答案为C。 

2.这是一道细节题。从第二自然段得出结论，他忘记扎安全带的原因是他想赶快回家跑步，即进行体育锻炼。答案为C。 

3.这是一道细节题。从第五自然段最后一句可知，“thrown clear”可能造成伤害和死亡。其原因是当发生交通事故从车中被甩出来，着陆时就会十分危险。同时从车中被甩出来时必然要穿过挡风玻璃或车门，就可能造成伤亡。答案为B。

4.这是一道理解题。从第六自然段中可以了解到，人们误认为，如果扎上安全带，当汽车着火或沉入水中时，驾驶员就无法逃出车外。而实际情况是：不系安全带，人们在这种事故中的死亡率要比系安全带的可能性要高。答案为A。 

5.这是一道细节题。作者在文中举了三种情景的对照——不系安全带和系安全带，且列举了系和不系带来的后果，从而看出作者的态度是赞成系安全带的。答案为C。
