单选题 When I was preparing for my two-week vacation in southern Africa, ILine realized that the continent would be like nothing I had ever seen. I wanted to explore the urban streets as well as the savannah; it's always been my goal to have experiences on vacation that most other tourists fail to find. When my plans(5) were finalized, I left for Africa. The cultural differences were stunning, and made for plenty of laughter and confusion, but always ended up bringing smiles to our faces. What's funny now, though, more than ever, is how ridiculous I must have seemed to the people of one village when I played with their dog. Apparently, the role of dogs in America is nothing like it is in the third world.(10) When I walk the streets of my hometown now, I often find myself staring at all of the dogs and dog owners on the sidewalk. The way I see it, the American dog lives for the thrill: a hug, a scratch behind the ears, a new chew toy, another chance to fight against the leash it knows is only six feet long. Dog owners love to believe their animal is smart, while people who've never owned a dog tend to(15) believe the opposite. With a little training, the dogs don't bark, bite, or use the sofa as a toilet, but they do provide years of unconditional affection and loyalty, plus the occasional lame-brained escapade at which human onlookers can laugh. I am convinced African dogs could clobber their American counterparts. The relationship between a typical African and his dog is one of tangible mutualism.(20) I say tangible because the African sees himself as the dominant creature not to be bothered by the dog, but nevertheless responsible for providing for it. Hence, no attempts at behavioral training are ever made on African dogs. Instead, the African seizes power with a chunk of scrap meat and a bowl of water. The dog soon learns to quit yapping and biting at the hand that feeds him. Never does(25) the African speak to the animal. I'm not even sure such dogs get names. Their behavior becomes interestingly balanced, however, much to the surprise of the compassionate American dog lover.

单选题*Like her white friends Eleanor Roosevelt and Aubrey Williams, Mary Bethune believed in the fundamental commitment of the New Deal to Line assist the black American's struggle and in the (5) need for blacks to assume responsibilities to help win that struggle. Unlike those Of her white liberal associates, however, Bethune's ideas had evolved out of a long experience as a "race leader." Founder of a small black college in (10) Florida, she had become widely known by 1935 as an organizer of black women's groups and as a civil and political rights activist. Deeply religious, certain of her own capabilities, she held a rela- tively uncluttered view of what she felt were the (15) New Deal's and her own people's obligations to the cause of racial justice. Unafraid to speak her mind to powerful whites, including the President, or to differing black factions, she combined faith in the ultimate willingness of whites to discard (20) their prejudice and bigotry with a strong sense of racial pride and commitment to Negro self-help. More than her liberal white friends, Bethune argued for a strong and direct black voice in initi- ating and shaping government policy. She pur- (25) sued this in her conversations with President Roosevelt, in numerous memoranda to Aubrey Williams, and in her administrative work as head of the National Youth Administration's Office of Negro Affairs. With the assistance of Williams, (30) she was successful in having blacks selected to NYA posts at the national, state, and local levels. But she also wanted a black presence throughout the federal government. At the beginning of the war she joined other black leaders in demanding (35) appointments to the Selective Service Board and to the Department of the Army; and she was instrumental in 1941 in securing Earl Dickerson's membership on the Fair Employment Practices Committee. By 1944, she was still making (40) appeals for black representation in "all public pro- grams, federal, state, and local," and "in policy- making posts as well as rank and file jobs." Though recognizing the weakness in the Roosevelt administration's response to Negro (45) needs, Mary Bethune remained in essence a black partisan champion of the New Deal during the 1930s and 1940s. Her strong advocacy of admin- istration policies and programs was predicated on a number of factors: her assessment of the low (50) status of black Americans during the Depression; her faith in the willingness of some liberal whites to work for the inclusion of blacks in the govern- ment's reform and recovery measures; her convic- tion that only massive federal aid Could elevate (55) the Negro economically; and her belief that the thirties and forties were producing a more self- aware and self-assured black population. Like a number of her white friends in government, Bethune assumed that the preservation of democ- (60) racy and black people's "full integration into the benefits and the responsibilities" of American life were inextricably tied together. She was con- vinced that, with the help of a friendly govern- ment, a militant, aggressive "New Negro" would (65) emerge out of the devastation of depression and war, a "New Negro" who would "save America from itself," who would lead America toward the full realization of its democratic ideas.
