下面是几则寓言小故事:

小题1:An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, aiming at the dove. The ant, perceiving his design, stung him in the foot. In pain the birdcatcher shouted, and the noise made the dove take wing.

小题2:Two men were travelling 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 snout, 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 traveller descended 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.”

小题3:A prince had some monkeys trained to dance. Being naturally good at learning, they showed themselves 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 mischief, 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 spectacle thus came to an end in the laughter and ridicule of the audience.

小题4:A cock was once strutting up and down the farmyard among the hens when suddenly he noticed something shining in the straw. "Ho! ho!" said he, "that’s for me," and soon rooted it out from beneath the straw. It turned out to be a pearl that by some chance had been lost in the yard. “You may be a treasure,” signed the cock, “to man, but for me I would rather have a single barley-corn.”

小题5:An old man on the point of death summoned his sons around him 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 tried hard, 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.
