    　　The largest bird that cannot fly also happens to be the largest living bird in the world．This is the huge North African ostrich(鸵鸟)．When the male, or cock, is fully grown, he reaches a height nearly eight feet and many weigh close to three hundred pounds．His wings are very small and the wing feathers are very soft, therefore he does not fly．

    　　You have probably heard the old saying about the “foolish ostrich burying his head in the sand”．Well, the ostrich is not nearly as foolish as he is said to be．In the daytime, when the hen is sitting on the eggs, she does not want to be seen; but, instead of sticking her long neck up into the air, she bends her neck and head down and presses flat along the sand．That way, she can best protect the eggs and herself．

    　　Because the ostrich cannot fly up into the air to escape from danger on the ground, he has to remain alert (警惕的)at all times．Luckily, he has very sharp eyesight and hearing．As he lives in the desert and open plains, he can stop danger in time to race away．The ostrich can run so fast that it almost seems as if he were flying．

    　　Sometimes, when a person has a small appetite(食欲), we say that he “eats like a bird”．That bird is not the ostrich! An ostrich will eat anything under the sun．When an ostrich died in a zoo, scientists cut it open to see what it had eaten．Here are some of the things found in the bird’s stomach：three pieces of wood, part of a film roll, a nail, a screw, a French coin, three handkerchiefs, four pennies, part of a chain and eighteen pieces of wire．

    Pigs are always considered dirty animals because they roll in mud．But in fact they prefer  being quite clean．They cover themselves with mud to help stay cool．During cooler weather,  they prefer to stay clean．So do elephants, who also cover themselves in dust or mud to keep cool．When they find a place with clean water they will take a bath，using their long noses to give  themselves—or each other—a nice shower
    Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don’t like to take water baths because water is not warm enough for them．So, instead, they roll  around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease
    Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth  cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any  parasites(寄生虫)between the crocodile’s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．
    You wouldn’t think fish would need baths．But some undersea parasites live under the  fish’s skin．“Cleaner” fish，like the wrasse(隆头鱼)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food．

    One day，four lawyers were riding their horses along a country road. There had been a rain. Water was dripping (滴) from the trees，and the grass was wet. They rode slowly，talking and laughing. Suddenly they heard some noises from the tree above them. “What is the matter?” asked the first lawyer. “Oh, it's only some old birds!” said the second lawyer. “The storm made one of the babies fall out of the nest. It is too young to fly, and the mother bird is very worried.” “What a pity! It’ll die down there in the grass,” said the third lawyer. “It doesn't matter. It's only a bird,” said the second lawyer. Then they rode on, talking and laughing as before. But the fourth lawyer, whose name was Abraham Lincoln, stopped. He got down from his horse and took the little one in his big warm hands.

    “Never mind, my little fellow ,” said Mr. Lincoln. “I will put you back in your little nest.” He climbed up the tree and put the bird softly into their warm little home. A few minutes later, Mr. Lincoln joined them again. His shoes were covered with mud and he was wet. Then the other three laughed at him. They thought it was foolish for a strong man to do so much just for a young bird. “Gentlemen,” said Mr. Lincoln, “I could not sleep tonight if I had left the helpless bird in the grass.” Later Abraham Lincoln became very famous as a lawyer.
