单选题 Sporting activities are essentially modified forms of hunting behaviour. Viewed biologically, the modern footballer is in reality a member of a hunting group. His killing weapon has turned into a harmless football and his prey into a goal-mouth. If his aim is accurate and he scores a goal, he enjoys the hunter's triumph of killing his prey. To understand how this transformation has taken place we must briefly look back at our forefathers. They spent over a million years evolving as cooperative hunters. Their very survival depended on success in tie hunting-field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They cooperated as skillful male-group attackers. Then about ten thousand years ago, after this immensely long period of hunting their food, they became farmers. Their improved intelligence, so vital to their old hunting life, was put to a new use—that of controlling and domesticating their prey. The hunting became suddenly out of date. The food was there on the farms, awaiting their needs. The risks and uncertainties of the hunting were no longer essential for survival. The skills and thirst for hunting remained, however, and demanded new outlets. Hunting for sport replaced hunting for necessity. This new activity involved all the original hunting sequences but the aim of the operation was no longer to avoid starvation. Instead the sportsmen set off to test their skill against prey that were no longer essential to their survival. To be sure, the kill may have been eaten but there were other much simpler ways of obtaining a meaty meal.

单选题 I fell in love with the minister's son in winter when I turned fourteen. He was not Chinese.For Christmas I prayed for the boy, Robert. When I found out that my parents had invited the minister' s family over for Christmas Eve dinner, I cried in panic What would' Robert think of our shabby Chinese Christmas? What would he think of our noisy Chinese relatives who lacked proper American manners? On Christmas Eve, my mother created abundant Chinese food.And then they arrived--the minister' s family and all my relatives.Robert greeted hello, and I pretended he was not worthy of existence. Dinner threw me deeper into disappointment.My relatives licked(舔)the ends of their chopsticks and reached across the table.Robert and his family waited patiently for a large plate to be passed to them.My relatives murmured with pleasure when my mother brought out the whole steamed fish.Robert made a face.Then my father reached his chopsticks just below the fish eye and picked out the soft meat. 'Amy, your favorite,' he said, offering me the tender fish cheek.I wanted to disappear. At the end of the meal, my father leaned back and burped(打嗝)loudly, thanking my mother for her fine cooking.'It's a police Chinese custom to show you are satisfied, 'explained my father to our astonished guests.Robert was looking down at his plate with a reddish face.The minister managed to bring up a quiet burp.I was shocked into silence for the rest of the night. After everyone had gone, my mother said to me, 'You want to be the shame as American girls on the outside. 'She handed me an early gift. It was a miniskirt. 'But inside you must always be Chinese. You must be proud you are different. Your only shame is to have shame. ' It was not until years later that I was able to fully appreciate her lesson and the purpose behind her particular menu. For Christmas Eve that year, she had chosen excellent Chinese food.

单选题 'Family' is of course an elastic word. But when British people say that their society is based on family life, they are thinking of 'family' in its narrow, peculiarly European sense of mother, father and children living together alone in their own house as an economic and social unit. Thus, every British marriage indicates the beginning of a new and independent family— hence the tremendous importance of marriage in British life. For both the man and the woman, marriage means leaving one's parents and starting one's own life. The man's first duty will then be to his wife, and the wife's to her husband. He will be entirely responsible for her financial support, and she for the running of the new home. Their children will be their common responsibility and theirs alone. Neither the wife's parents nor the husband's, nor their brothers or sisters, aunts or uncles, have any right to interfere with them—they are their own masters. Readers of novels like Jane Austen's Pride and Prejudice will know that in former times marriage among wealthy families were arranged by the girl's parents, that is, it was the parents' duty to find a suitable husband for their daughter, preferably a rich one, and by skillful encouragement to lead him eventually to ask their permission to marry her. Until that time, the girl was protected and maintained in the parents' home, and the financial relief of getting rid of her could be seen in their giving the newly married pair a sum of money called a dowry. It is very different today. Most girls of today get a job when they leave school and become financially independent before their marriage. This has had two results. A girl chooses her own husband, and she gets no dowry.
