9 下面有五则寓意。阅读A-F的寓言故事，然后匹配与之对应的寓言故事。其中有一个故事是多余的。 ( )1. Not everything you see is what it appears to be. ( )2. He who loses freedom loses all. ( )3. Misfortune tests true friendship. ( )4. Union gives strength. ( )5. Precious things are for those that can prize them A A wolf was almost dead with hunger. A housedog saw him, and asked, "Friend, your irregular life will soon ruin you." "Why don"t you work steadily as I do, and get your food regularly?" "I would have no objection," said the wolf, "if I could only get a place." "I will help you," said the dog. "Come with me to my master, and you shall share my work." So the wolf and the dog went to the town together. On the way the wolf saw that there was no hair around the dog"s neck. He felt quite surprised, and asked him why it was like that? "Oh, it is nothing," said the dog. "Every night my master puts a collar around my neck and chains me up. You will soon get used to it." "Is that the only reason?" said the wolf. "Then good-bye to you, my friend. I would rather be free." B Two men were traveling together, when a bear suddenly met them on their path. One of them climbed up quickly into a tree and hid himself in the branches. The other, seeing that he must be attacked, fell flat on the ground, and when the bear came up and felt him with his nose, and smelt him all over, he held his breath, and pretended to be dead as much as he could. The bear soon left him, for he will not touch a dead body. When he disappeared, the other traveler slid down from the tree, and asked his friend what it was the bear had whispered in his ear. "He gave me this advice," his companion replied. "Never travel with a friend who deserts you at the approach of danger." C A prince had some monkeys trained to dance. Being naturally good at learning, they showed themselves most excellent pupils, and in their rich clothes and masks, they danced as well as any of the courtiers. Their performance was often repeated with great applause, till on one occasion a courtier, bent on trick, took from his pocket a handful of nuts and threw them upon the stage. The monkeys at the sight of the nuts forgot their dancing and became (as indeed they were) monkeys instead of actors. Pulling off their masks and tearing their robes, they fought with one another for the nuts. The dancing show thus came to an end in the laughter and jokes of the audience. D A cock was once walking up and down the farmyard among the hens when suddenly he noticed something shinning in the grass. "Ho! ho!" said he, "that"s for me," and soon rooted it out from beneath the grass. It turned out to be but a pearl that by some chance had been lost in the yard. "You may be a treasure," sighed the cock, "to man, but for me I would rather have a single corn." E Lion was awakened from sleep by a Mouse running over his face. Rising up in anger, he caught him and was about to kill him, when the Mouse pitifully begged, saying:"If you would only spare my life, I would be sure to repay your kindness." The Lion laughed and let him go. It happened shortly after this that the Lion was caught by some hunters, who tied him by strong ropes to the ground. The Mouse, recognizing his roar, came up, and bit the rope with his teeth, and setting him free, exclaimed:"You joked the idea of my ever being able to help you, not expecting to receive from me any repayment of your favor. But now you know that it is possible for even a Mouse to grand benefits on a Lion." F An old man on the point of death had his sons aside to give them some parting advice. He ordered his servants to bring in a bunch of sticks, and said to his eldest son:"Break it." The son strained and strained, but with all his efforts was unable to break the Bundle. The other sons also tried, but none of them was successful "Untie it," said the father, "and each of you take a stick." When they had done so, he called out to them:"Now, break," and each stick was easily broken.
