(16分)阅读材料,回答问题。   

1800年以后,美国和西欧一些国家的工业技术和军事技术迅速进步。

而与此同时,亚洲和非洲的大部分国家陷入了困境。中国的经济发展和行政管理滞后于其人口增长的速度,因而导致了民众的叛乱……这些负面趋势带来的影响是,在19世纪,欧洲国家(和美国)在与亚洲和非洲的弱国打交道时,越来越多地使用武力和廉价商品。

并不是殖民主义和武力征服导致了西方的崛起,而恰恰相反—是西方的崛起(依   靠技术力量)和其他地区的衰落才使得欧洲强权得以在全世界不断扩张。  

——[美]杰克·戈德斯通《为什么是欧洲?——世界史视角下的西方崛起》

(1)据材料,分别说明导致欧洲崛起和亚洲国家衰落的最基本因素。并分析欧洲国家“使用武力和廉价商品”对中国产生的影响。(10分)

(2)“不是殖民主义和武力征服导致了西方的崛起”,作者的这种观点是否恰当,为什么?由此可见,分析评价历史问题所应坚持的基本方法是什么?(6分)

在北京某外企工作的陆小姐,在伏案工作三日,吃完第六碗方便面时,给家里人挂了个电话“诉苦”,不过她说的并不是连日工作的辛苦,而是“我现在天天吃方便面!苦死啦!”
吃方便面=辛苦,这样的等同,在较贫困的农民那里可能有点儿不可思议,但对长期在野外工作或学府苦读的学者们来说,吃方便面确实是一件很苦的事情。中国农科院农产品加工综合研究中心的张涛先生说:“现在人们只会在没有时间做饭的情况下才去买方便面或速冻饺子,方便食品在我国还没有取得正餐的地位,顶多是个应急替代产品。”方便面口味单调,营养价值低,长期食用不符合健康要求,这基本上是消费者们的共识。“吃上三顿就吃腻了!”很多人如是说。实际上,好吃、快捷、富于营养的食品才是与现代人的生活节奏相适应的必须之物。

陆小姐打电话是为了告诉家里人:

A.连续工作太苦
B.总吃方便面太苦
C.身体出现了问题
D.打算调动工作
