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、It went out of use 300 years ago.
B、It was invented after the short bow.
C、It was discovered before the fire and the wheel.
D、It’s still in use today.
答案
B
解析
判断题。浏览选项可知,选项和“it”的知识有关,需根据细节加以判断。文章在讲到长弓时说到The long bow was most likely discovered when someone found out that a five—foot piece ofwood made a better bow than a three—foot piece(长弓很可能是人们发现五尺的木头做出来的弓要比三尺做出来的弓更好时被发明出来的),这就说明了长弓是晚于短工发明的,故B正确。
