⑤强调对外关系的灵活性。戈尔巴乔夫指出在对外政策中要采取多种办法选择不同的策略路线达到既定目标。在外交谈判中不要为自己制造死胡同,也不要给对方制造死胡同,要善于迎合伙伴,寻求接触点。在这种思想指导下,苏共采取的对外战略是以军控为中心的缓和战略,具体政策是继续与美国就裁军、消减核武器、限制地区冲突等问题进行谈判,缓解苏美关系;对西欧争取建立“全欧大厦”;对东欧实行纠偏、不干涉政策;对中国改善关系,实现关系正常化;调整与第三世界国家关系,解决阿富汗、柬埔寨等问题。 3、影响:①经济改革措施仓促上马,缺少宏观决策和相应的配套措施;加上戈尔巴乔夫没有放弃苏联的传统做法,继续优先发展重工业,致使改革未达到预期的效果,苏联经济持续下滑②经济体制改革受挫后,把改革的重点转向政治领域,最终导致国内局势的失控和苏联的解体。

★教后记:历史教学的最高目标不是单纯的记忆和培养能力,而是树立正确的历史观,培养学生的历史责任感。从这一点讲,新课标及新课标教材给老师极大的发挥空间,摆脱了以往的“教教材”,真正实现了 “用教材教”,只有这样,教师才不只是一个“备课”的“教书匠”,而是一名设计教学“设计师”,以教材为砖瓦,建造有自己独特风格的教育大厦。这是我设计教学的出发点。开放式的课堂需要思想开放的教师,但对教师的课堂驾驭能力要求更高,否则“一放就活,一活就乱”,只求课堂热闹,热闹过后,学生一无所获,那么这样的开放课堂依然是失败的。开放式的课堂并不是任由学生说,教师必要的引导与客观的评价尤为重要。★问题解答⊙【学思之窗】请谈谈,火车机车的不断改进,给国民经济发展、百姓生活带来怎样的影响?答案提示:运输量大,有利于各地区的物资交流和劳动力流动,促进经济发展;交通便利快捷;机车内部环境舒适,给百姓出行带来方便。

②其他货币与美元挂钩:即各会员国货币对美元的汇率按各自货币的含金量与美元确定固定比价。各国货币与美元的汇率可按各国货币含金量与美元含金量之比来确定,这称为法定汇率。例如,1946年一英镑的含金量为3.58134克,一美元的含金量为0.888671克,则英镑和美元的含金量之比1英镑=4.03美元就是法定汇率。这一规定,使美元等同于黄金,美元从此有了“美金”的说法;与美元比起来,其他国家的货币处于从属地位,确立了美元在国际货币体系中的中心地位、主导地位正如当时美国财政部长福勒所说:“各个行星围绕着太阳转,各国货币围绕着美元转。”小结: “布雷顿森林体系”是一个以美元为中心的世界货币体系,美国通过布雷顿森林体系,掌握了资本主义世界的经济命脉。(2)影响:①为世界货币关系提供了统一的标准和基础,有利于维持战后世界货币体系的正常运转,为世界经济的恢复和发展创造了条件。

战国阴阳五行家邹衍认为,历史中的朝代更替是由于五德运行产生的影响。按照邹衍的学说,每个朝代必须与五德之一相连,因此,这个朝代就应当遵循这五德之一的要求来运转。董仲舒修改了这个理论,认为朝代的更替不是依循五德运行的顺序,而是依循“三统”,即黑统、白统、赤统的顺序。他在《三代改制质文》中说:每个朝代都依循一统,每统又各有其为政的系统。按董仲舒的说法,夏朝代表黑统,商朝代表白统;周朝则是赤统。夏、商、周三朝完成了这一历史循环。之后,历史又开始一次新的循环,新的朝代又应当代表黑统。继承周朝统治的既不是秦朝,也不是汉朝,而是孔子,他承受天命,创立了黑统。孔子所受天命,不是一种“法统”,而是一种“道统”。董仲舒说:“《春秋》大一统者,天地之常经,古今之通谊也。今师异道,人异论,百家殊方,指意不同,是以上亡以持一统;法制数变,下不知所守。臣愚以为诸不在六艺之科孔子之术者,皆绝其道,勿使并进。邪辟之说灭息,然后统纪可一而法度可明,民知所从矣。”

Example:One day, a poor boy who was trying to pay his way through school by sending newspapers door to door found that he only had one dime(一角)left. He was so hungry that he decided to beg for a meal at the next house.However, he lost his nerve when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him a large glass of milk. He drank it slowly, and then asked, “How much do I owe you?” “You don’t owe me anything,” she replied, “Mother has taught me never to accept pay for a kindness.” “Then I thank you from the bottom of my heart.” With these words, Howard Kelly left that house.Years later the woman became badly ill and was finally sent to the hospital in a big city. Dr. Howard Kelly, now famous, was called in. When he heard the name of the town she came from, a strange light filled his eyes. Dressed in his doctor’s clothes, Dr. Kelly went into her room and recognized her at once. From that day on, he gave special attention to her, and decided to do his best to save her life.At last the woman was saved. Dr. Kelly asked the business office to pass the final bill to him. He looked at it and then wrote something on the side. The bill was sent to the woman’s room. She was afraid to open it because she was sure that it would take the rest of her life to pay for it off. Finally she looked, and the note on the side of the bill caught her attention. She read these words: “Paid in full with a glass of milk, Dr. Howard Kelly.” Tear of joy flooded her eyes.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

过渡:在实际生活中,城市内部空间结构并非完全按照这一经济规律呈现,而是更具复杂性。这说明除了经济因素外,还有很多其他因素在起作用,请大家结合你的认识、图2.9和案例1:纽约市的少数民族区谈谈你的看法。(2)其他因素I.收入 —— 形成不同级别住宅区的常见原因。有能力支付昂贵租金和选择最佳居住环境的人,其居住地往往形成高级住宅区。II.知名度 ——城市内某些地区在历史、文化或经济方面具有很高的声誉,这往往会吸引更多新的住宅或商场建在该处,以提高其知名度。III.种族聚居区的形成 ——在有些城市的某一区域内,如果某个种族或宗教团体占优势,就可能形成种族聚居区。如纽约市的唐人街、哈林区、小意大利区等。IV历史因素——城市的建筑物和街道设计可以维持久远,早期的土地利用方式对日后的功能分区有着深远的影响。3、城市内部空间结构的形成和变化

写作指导:第一题要求写出自然美,在自然美中融进自己的感情。小路、流水、山峦、森林、天空、大海……都是实体事物,因此首先要求用写生的办法把它们表现出来,要写得准确,写出它们的特点和个性,尤其是写出它们的美。同时,也要把赞美之情不落痕迹地融化在描写之中。第二题是写一幅风景画或一张风景照片中的自然美景,以及美景中的一些细节,同时把自己心动的感觉写出来。在这里,关键是找到画或照片中的美,找到心动的感觉,如果找到了,再用文字把这美和感觉表达出来。当然,写风景美和写自己的感觉应是乳水交融的。第三题是用动情的笔墨把自己的一种经历写出来。这些经历似乎都是细节,都不是惊天动地的大事。是细节,就容易碰到,在题目列举的四种中,学生不难找到。即使不在这四种中,也可以,只要这种经历给了自己心灵以震撼或潜移默化的影响。
