单项选择题 For a long time we have worked hard at isolating the individual family. This has increased the mobility of individuals; and by encouraging young families to break away from the older generation and the home community, we have been able to speed up the acceptance of change and the rapid spread of innovative behavior. But at the same time we have burdened every small family with tremendous responsibilities once shared within three generations and among a large number of people - the nurturing of small children, the initiation of adolescents into adulthood, and care of the sick and disabled and the protection of the aged. What we have failed to realize is that even as we have separated the single family from the larger society, we have expected each couple to take on a range of obligations that traditionally have been shared within a family and a wider community. So all over the world there are millions of families left alone, as it were, each in its own box—parents faced with the specter of what may happen if either one gets sick, children fearful that their parents may end their quarrels with divorce, and empty-handed old people without any role in the life of the next generation. Then, having reduced little by little to almost nothing the relationship between families and the community, when families get into trouble because they cannot accomplish the impossible, we turn their problems over to impersonal social agencies, which can act only in a fragmented way because they are limited to patchwork programs that often are too late to accomplish what is most needed. Individuals and families do get some kind of help, but what they learn and what those who work hard within the framework of social agencies convey, even as they try to help, is that families should be able to care for themselves.According to the author, when young families are isolated,______.A．old people can easily accept the changeB．people can move from place to placeC．individuals can hardly become innovativeD．economy develops at high speed

单项选择题 Most people think of lions as strictly African beasts, but only because they've been killed off almost everywhere else. Ten thousand years ago lions spanned vast sections of the globe, and so did people, who--as they multiplied and organized—put pressure on competitors at the top of the food chain. Now lions hold only a small fraction of their former habitat, and Asiatic lions, a subspecies that split from African lions perhaps 100,000 years ago, hang on to an almost impossibly small slice of their former domain. India is the proud steward of these 300 or so lions, which live primarily in a 560-square-mile (1,450-square-kilometer) sanctuary. It took me a year and a half to get a permit to explore the entire Gir Forest—and no time at all to see why these lions became symbols of royalty and greatness. A tiger will slink through the forest unseen, but a lion stands its ground, curious and unafraid—lionhearted. Though they told me in subtle ways when I got too close, Gir's lions allowed me unique glimpses into their lives during my three months in the forest. It's odd to think that they are threatened by extinction; Gir has as many lions as it can hold—too many, in fact. With territory in short supply, lions prowl the periphery of the forest and even leave it altogether, often clashing with people. That's one reason India is creating a second sanctuary. There are other pressing reasons: outbreaks of disease or natural disasters. In 1994 canine distemper killed more than a third of Africa' s Serengeti ]ions—a thousand animals—a fate that could easily befall Gir's cats. These lions, saved by a prince at the turn of the 20th century, are especially vulnerable to disease because they descend from as few as a dozen individuals. 'If you do a DNA fingerprint, Asiatic lions actually look like identical twins,' says Stephen O'Brien, a geneticist who has studied them. Yet the perils are hidden, and you wouldn't suspect them by watching these lords of the forest. The lions exude vitality, and no small measure of charm. Though the gentle intimacy of play vanishes when it's time to eat, meals in Gir are not necessarily frenzied affairs. For a mother and cub sharing a deer, or a young male relishing an antelope, there's no need to fight for a cut of the kill. Prey animals are generally smaller in Gir than they are in Africa, and hunting groups tend to be smaller as well. The lions themselves aren't as big as African lions, and they have shorter manes and a long fold of skin on their undersides that many lions in Africa don't have.What impressed the author most when he went to watch the lions in the Gir Forest?A．The lions were on the brink of extinction.B．They were suffering from a fatal disease.C．They allowed him to see their vitality and charm at close quarters.D．Mother lion and her cub shared a deer.

单项选择题 Leacock was probably the first Canadian to qualify as a 'pro-American British imperialist.' A colleague, Prof. John Culliton, said of him, 'Long before Winston Churchill, Leacock was saving the Empire every Monday, Wednesday and Friday at 3 p.m. in Room 20.' He was also ahead of his time in prodding Americans anti BriTons toward greater friendship and understanding. His feeling for both sides of the Atlantic came naturally. He was born on the Isle of Wight in 1869, and emigrated to Canada as a six-year-01d. On his retirement from McGill, influential English friends urged him to return to live in the land of his birth. He refused, saying, 'I' d hate to be so far away from the United States. It's second nature, part of Our lives, to be near them. Every Sunday morning we read the New York funny papers. All week we hear about politics in Alabama and Louisiana, and whether they caught the bandits who stole the vault of the National Bank — well, you know American news. There's no other like it.' In the eight years of his retirement, Stephen produced the work he believed most likely to endure. It was far removed from the kind of wit which had made him famous. He described his history, Montreal: Seaport and City, as 'the best job I've done.' Unlike most historical works it bubbles with the author' s laughter. In his foreword, after thanking two former colleagues for checking the manuscript, he added that any errors which remained obviously must be theirs. 'Acknowledging these debts,' he concluded, 'I also feel that I owe a good deal of this book to my own industry and effort.' Midway through World War II, I asked Stephen if he would write a foreword for a book I had written on the Canadian navy and its gallant role in convoy escort. He agreed. Some time later he handed me more than 20,000 words, in which he had told the whole fascinating background story of Canada's lifelong relationship to the sea. His research was staggering to a reporter who had simply described events and engagements to which he had been an eyewitness. 'I got interested in the subject,' he explained. 'If you don't like it, throw it away and I'll write something shorter.' Not a word was changed. To my joy, the book appeared under our joint by-lines. Soon after, throat cancer took Stephen from the thousands of Old McGillers who loved him. Leacock loved human beings for their little vanities and pretensions — and laughed at his own. The fictional town of Mariposa of his famous 'Sunshine Sketches' is obviously Orillia,Ontario, where Leacock built a summer home and developed a farm, which, he said, 'used to lose a few dollars a year, but by dint of hard work and modernization, I have contrived to' turn that into a loss of thousands.' The citizens of Orillia had tittle difficulty in self-identification when the book reached town, but they soon realized that Leacock had ribbed his own idiosyncrasies more sharply than he had pinpointed theirs. Today's Orillians speak of him with the awe giyen to any community's adopted son, though it was he who adopted Mariposa-OriUia. Stephen Leacock was so honestly simple that to many men he seemed to be a mass of complexities. To the world he remains the man of laughter. His greatest achievement, however, was that he taught thousands of young men and women to want to know. By example he proved one simple fact to all of us who attended his classes, certainly to that numerous crew who came to enjoy his friendship — that the right ofoutspoken dissent is the free man's most precious heritage. Such men do not often pass this way.Why was Leacock dubbed as a 'pro-American British imperialist'?______A．Because he was a Briton who adored American politics.B．Because he liked to read American newspapers.C．Because he lectured on the importance of friendship between U.S. arid Britain.D．Because he chose to live close to America.
