江 * * 同志在中共十六大的报告上重点阐述了“举什么旗,走什么路”的问题。在中国近代、现代史上,中国人民为“举什么旗,走什么路”的问题进行了不断的探索。

阅读材料,结合所学知识回答问题(12分)

材料一  “红军、游击队和红色区域的建立和发展,是半殖民地中国在无产阶级领导之下的农民斗争最高形式和半殖民地农民斗争发展的必然结果;并且无疑义地是促进全国革命高潮的最重要因素。”“单纯的流动游击政策,不能完成促进全国革命高潮的任务,而朱德毛 * * 式、方志敏式之有根据地的,有计划地建设 * * 的,深入开展土地革命的,扩大人民武装的路线无疑又是正确的。”    

——毛 * * 《星星之火,可以燎原》

材料二 “中国的特点是:不是一个独立的民主的国家,而是一个半殖民地半封建的国家;在内部没有民主制度,而受封建制度压迫;在外部没有民族独立,而受帝国主义压迫。因此,无议会可以利用,无组织工人举行罢工的合法权利。在这里, * * 党的任务,基本的不是经过长期合法斗争,也不是先占城市而后去乡村,而是走相反的道路。”

——毛 * * 《战争和战略问题》

材料三 社会主义的本质,是解放生产力,发展生产力,消灭剥削,消除两极分化,最终达到共同富裕。……计划多一点还是市场多一点,不是社会主义与资本主义的本质区别。计划经济不等于社会主义,资本主义也有计划;市场经济不等于资本主义,社会主义也有市场。计划和市场都是经济手段。

请回答:

(1)新民主主义革命时期和新中国成立后,中 * * 党从“走俄国人的路”发展到“走自己的路”。分别说明两个时期“走俄国人的路”和“走自己的路”各指什么?(4分)

Reading comprehension.

     Martha had been working for Miller Laboratories for two years, but she was not happy there. Nothing

significant had happened in the way of promotions or salary increases. Martha felt that her supervisor, a

younger and less experienced person than she, did not like her. In fact, the supervisor often said unpleasant

things to her.

     One day, while talking with her friend Maria, she mentioned how discouraged she was. Maria gave her

the name of a cousin of hers who was director of Human Resources Department for a large chemical

company. Martha called him the next day and set up an interview on her lunch hour.

     During the interview, Mr. Petri said, "You're just the kind of person we need here. You're being wasted

in your other job. Give me a call in a day or two. I'm sure we can find a place for you in our organization."

Martha was so happy she almost danced out of the building.

     That afternoon, Ruth Kenny, her supervisor, saw that Martha had come in ten minutes late from her lunch

hour and she said. "Oh, so you finally decided to come back to work today?"

     This was the last straw. She could not take another insult. Besides, Mr. Petri was right:she was being

wasted in this job.

     "Look," she said angrily, "if you don't like the way I work, I don't need to stay here, I'll go where I'm

appreciated! Good-bye!" She took up her things and stormed out of the office.

     That night she called Maria and told her what had happened and then asked Maria, "What do you think?"

     "Well," said Maria carefully, "are you sure about the other job?"

     "Well, not exactly, but …"

     Maria continued, "Will you be able to get a recommendation from Ms.Kenny if you need one?"

     "A recommendation?…from Ms.Kenny?" hesitated Martha, in a worried tone.

     "Martha, I hope you didn't burn your bridges," Maria said. "I think I would have handled it differently."
