现代化是世界历史发展的必然进程，是以工业化为核心引起的全面变革。阅读材料，回答问题。

材料一：明清时期，从全球角度看，在思想革命、科学革命、政治革命与工业革命的推动下，西方国家已在从农耕文明转向工业文明的路径上高歌猛进。由于明清两朝统治者未能认清时代潮流，采取了逆大势而行的政策，社会转型因此难以启动。直到鸦片战争爆发，在西方坚船利炮的逼迫下，中国才开始艰难地探索现代化的路径。

材料二：对18世纪的英国，市场机制究竟如何发挥作用，以及给英国社会带来了怎样的影响。针对这一系列问题进行讨论，出现了“斯密派”和“马克思派”。“斯密派”和“马克思派”都承认18世纪的英国已经出现市场经济，商品价格最终由供需决定。其分歧在于，市场竞争在多大程度上是完美的，该在何种程度上实行自由的市场竞争以及随之产生的影响。“斯密派”认为“看不见的手”占绝对优势。在他们看来，英国的工业革命应当归因于早在18世纪英国经济就实现完全的自由竞争，与之相伴的还有稳步扩展的市场，以及其所提供的创新和增长的广阔平台。“马克思派”认为，英国之所以发生资本积累和投资行为是因为，从生产角度看，规模经济与范围经济受到政治领导的保护和支持而大行其道。以众多英国人变为完全依赖工资的劳动力这一事实为例，他们认为没有政府的合谋协助是不可想象的。

材料三：直到十一届三中全会以后，中国才以主动和积极的姿态全力推动向现代社会的转型，开始了真正意义上的社会转型，我把它叫做中国社会转型的快速发展阶段。中国社会转型包括从原有的计划经济体制向社会主义市场经济体制转变、农业社会向工业社会转变、乡村社会向城镇社会转变、封闭、半封闭社会向开放社会转变、伦理社会向法理社会、（民主）制度社会转变等。

    Jackson was driving back home along a road one evening. He just lost his job. It was winter and it was very cold, just like his feelings.

    An old lady with her car was standing on one side of the road. The lady looked very worried. She needed help. No one stopped to help her. Jackson stopped in front of her and got out of his car. Even when he put a smile on his face, the old lady still looked worried. Was he going to hurt her? He didn't look safe, and he looked poor and hungry.

    Jackson knew how she felt. He said." I'm here to help you, madam. Why don't you wait in my car? By the way, my name is Jackson."

    The lady thought for a while and then went into his car. There was something wrong with her car. Jackson went under her car to repair it. After a long time, he finished it. He got dirty and his hands hurt. Then the lady told him that her name was Annie. She asked Jackson how much she should pay for his help.

    Jackson never thought about getting money. This was not a job to him. This was helping someone in need. He told her that if she really wanted to pay him back, the next time she saw someone who needed help, she should give that person help.
