Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.
people in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products' safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem.
Being thrown into glass and mental cars parts, or being thrown from the car can really hurt or even kill you.
The safety belt's main purpose is to pull you back if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.
Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts. Most people are demanding air bags in the cars they buy. Effective as they are, they can't take the place of safety belts.
Drunk driving crashes are less likely to happen if you don't drink. Many people have realised that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties(处罚) for drinking and driving.
A. How to drive safely?
B. You are safer in a large car
C. How to protect ourselves in the highway?
D. Air bags are not installed in all cars.
E. That's why safety belts should be worn.
F. Drunk driving is the most serious problem.
G. But the protection provided by air bags is limited in side or rear crashes.

Answer 1

【答案】C；B；E；G；F
【解析】本文属于说明文，主要介绍了在高速公路上保护自身安全的四个建议。

（1）C 根据本文第一段Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.可推知，本文的主题是讲如何在高速公路上确保自身安全，故选C项。

（2）B 根据横线后一句"People in small cars are injured more often and more severely than people travelling in large cars.，，可知，高速公路上小车里的人更容易受伤，在大车上安全系数要髙些，故选B项。

（3）E 根据上文的"Being thrown into glass and metal car parts, or being thrown from the car can really hurt or even kill you."可知，此处上下句表示逻辑上的因果关系，说明不带安全带的危害。所以本句应该表示结论，故选E项。

（4）G 承接前一句中的".....Air bags are important."，并根据下文的"Effective as they are, they can't take the place of safety belts."可推知，虽然很多人在买车的时候，提出需要气囊，但是气囊还是无法代替安全带的作用。所以说安全气囊的作用还是有限的，故选G项。

（5）F 根据横线后一句"Many people have realized that drunk driving can lead to death and injury, prison time and other results."说明酒后驾车后果很严重，酒驾本身就是最危险的问题。故选F项。
