Bows and arrows are one of man’s oldest weapons. They gave early man an effective weapon to kill his enemies. The ordinary bow and short bow was used by nearly all early people. This bow had limited power and short range. However, man overcame these faults by learning to track his targets at a close range. The long bow was most likely discovered when someone found out that a five-foot piece of wood made a better bow than a three-foot piece. Hundreds of thousands of these bows were made and used for three hundred years. However, not one is known to survive today. We believe that a force of about one hundred pounds needs to pull the string all the way back on a long bow. For a long time the bow was just a bent stick and string. In fact, more changes have taken place in a bow in the past 25 years than in the last 7 centuries. Today, bow is powerful. It is as exact as a gun. In addition, it requires little strength to draw the string. Modern bows also have precise aiming devices. In indoor contests, perfect scores from 40 yards are common. The invention of bows itself ranks with discovery of fire and the wheel. It was a great step forward for man.
Questions 30 to 32 are based on the passage you have just heard.
30. Why did man have to track his target at a close range when using a short bow?
31. What does the passage tell us about the long bow?
32. What do we know about modern bows?
选项
A、Because it was too heavy.
B、Because it did not bend easily.
C、Because it did not shoot far.
D、Because its string was short.
答案
C
解析
因果关系题。浏览选项可知,题目考查原因。文章在说到早期人们用的短弓时这样描述This bow had limited power and short range(这种弓力量有限,射程很短),因此可想而知,要设中目标的话只有在近距离内瞄准目标,故选C。
