Some young soldiers who had recently joined the army were being trained in modern ways of fighting, and one of the things they were shown was how an unarmed man could trick an armed enemy and take his weapon away from him. First one of their two instructors took a knife away from the other, using only his bare hands; and then he took a rifle away from him in the same way.
After the lesson, and before they went on to train the young soldiers to do these things themselves, the two instructors asked them a number of questions to see how well they had understood what they had been shown. One of the questions was this: "Well, you now know what an unarmed man can do against a man with a rifle, imagine that you are guarding a bridge at night, and that you have a rifle. Suddenly you see an unarmed enemy soldier coming towards you. What will you do "
The young soldier who had to answer this question thought carefully for a few seconds before he answered, and then said, "Well, after what I have just seen, I think that the first thing I would do would be to get rid of my rifle as quickly as I could, so that the unarmed enemy couldn’t take it from me and kill me with it!/

The instructors were teaching the soldiers（）

A:how to use weapons B:how to manage without weapons C:how to beat the enemy barehanded D:how to fight with enemy

Passage Three
In this game you are in a tank and a screen shows your outside view. You gain points by shooting enemy tanks, supertanks, missiles(火箭)and saucers(飞碟).
Experts gain scores of around 150,000 points at this game. To get a high score you have to destroy twenty tanks as quickly as possible. After this the supertanks, missiles and saucers appear. These are worth far more points than the ordinary tanks.(The number of tanks you have to destroy before the supertanks appear are various on different machines.)
Try to get near an enemy tank from the side or back so it cannot shoot at you. Then when you get close, turn to it, line it up in your sights and fire before it turns to shoot at you. If you miss or are too slow, quickly get away by moving out of the enemy’s line of life. You can then move around the enemy and come in from another side.
When a supertank appears, try to destroy it. Then wait safely behind an obstacle(障碍物)for a missile or a flying saucer. The cubes are useful objects to hide behind as you can fire over them with out exposing yourself to danger. The missiles will fly straight at you, but they are difficult to hit. So do not shoot at them until they are quite close. The saucers are much easier to hit, but do not chase(追逐) them as you will be open to shoot from enemy’s tanks.

You are likely to be attacked if you （）

A:keep after a flying target B:hit a flying saucer C:fire straight at a missle D:keep chasing the enemy's tanks

Each Indian was supposed to keep his birth name until he was old enough to earn one for himself. But his playmates would always give him a name of their own. No matter what his parents called him, his childhood friends would use the name they had chosen. Often it was not pleasing, such as Bow Legs or Bad Boy. But sometimes a name fit so well that the youngster found it difficult to shake it off. If he could not earn a better one from a war later, he could be stuck with a name like Bow Legs for the rest of his life.
The Indian earned his real name when he was old enough for his first fight against the enemy. His life name depended on how he acted during this first battle. When he returned from the war, the whole tribe would gather and observe the ceremony in which he would be given his name by the chief. If he had done well, he would get a good name. Otherwise he might be called Crazy Wolf or Man-Afraid-of-a Horse. So an Indian’s name told his record or described the kind of man he was.
A man was given many chances to improve his name, however, if in a later battle he was brave in fighting against the enemy, he was given a better name. Some of our great fighters had as many as twelve names, all good and each better than the last.
An Indian’s names belonged to him for the rest of his life. No one else could use them. Even he himself could not give them away because names were assigned by the tribe, not the family. So no man could pass on his name unless the chief and the tribe asked him to do so.
Sometimes an Indian would be asked to give his name to a son who had performed a noticeable deed. I know of only three or four times when this happened. It is the rarest honor for a person--the honor of assuming his father’s name.
An Indian could be given the second name by ______.

A:his father B:the enemy C:the chief of the tribe D:his childhood friends
