How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?
In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.
Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces, they are taller, to reach higher branches. They have shorter tusks（象牙）, and most importantly, longer trunks to dig for water in riverbeds.
Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families. They drink only every 3 –4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders – they seldom root up trees and break fewer branches, and thus maintain what little food sources are available. Young elephants may even eat the dung（粪便）of the female leader of a group when facing food shortage.
During drought they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine（尿液）to make them muddy!
As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt as extraordinarily well to change as the desert elephant.

Dad came in the midnight. We heard every sound, but we pretended to be asleep.
Next morning he looked weak and thin, sitting in a chair by the kitchen fire. The light of the fire shone through his long empty sleeve. Everything went as usual. Grandma found something to do in the bedroom. Grandpa went out for some water. Mother, with her back to us, was getting the cakes ready for breakfast.
But nothing was right. When grandma came out of the bedroom, she walked on tiptoe. When grandpa came back, he said nothing about the weather. At breakfast Mother passed us the fruit and said something, but her voice was too high.
At last my sister, Lou, pushed back her chair. “It’s your turn to wash the dishes.” But I had washed the dishes the night before. I said nothing because it was not right to quarrel in front of Dad just home with the empty sleeve.
“It is your turn,” Lou said again. I looked at her in surprise.
“It is not,” I said because I suddenly remembered Mother had told us to go on as usual.
“Children, children,” Mother said in a quiet, glad kind of voice.
And Dad was smiling because he felt at home at last.

Drunken driving –sometimes called America’s socially accepted form of murder—has become a national epidemic (流行病). Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past ten years. A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts, but the drunken killing has recently caused so many well-publicized tragedies, especially concerning young children, that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20 years old drivers more than doubled, so the state recently upped it back to 21.
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop “responsible attitudes” about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests in many areas already, to a marked drop in accidents, some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who was “obviously drunk” and later drove off the road, killing a 9-year-old boy.
As the accidents continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years national prohibition of alcohol that began in 1919, which President Hoover called the “noble experiment”. They forgot that legal prohibition didn’t stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.

A．most Americans like drinking

B．heavy drinking is hard to avoid

C．many Americans are killed by drunk drivers

D．Americans are not shocked by traffic accidents

It was not yet eleven o’clock when a boat crossed the river with a single passenger who had obtained his transportation at that unusual hour by promising an extra fare.
While the youth stood on the landing-place searching in his pockets for money, the ferryman lifted a lantern, by the aid of which, together with the newly risen moon, he took a very accurate survey of the stranger’s figure. He was a young man of barely eighteen years, evidently country bred（长大的）, and now, as it seemed, on his first visit to town. He was wearing a rough gray coat, which was in good shape, but which had seen many winters before this one. The garments under his coat were well constructed of leather, and fitted tightly to a pair of muscular legs; his stockings of blue yarn must have been the work of a mother or sister, and on his head was a three-cornered hat, which in its better days had sheltered the grayer head of the lad’s father. In his left hand was a walking stick, and his equipment was completed by a leather bag not so abundantly stocked as to inconvenience the strong shoulders on which it hung. Brown, curly hair, well-shaped-features, bright, cheerful eyes were nature’s gifts, and worth all that art could have done for his adornment(装饰).
The youth, whose name was Robin, paid the boatman, and then walked forward into the town with a light step, as if he had not already traveled more than thirty miles that day. As he walked, he surveyed his surroundings as eagerly as if he were entering London or Madrid, instead of the little metropolis（都市）of a New England colony.
