郭怡敏（苏岩 饰）与余强（刘冠军 饰）已结婚七年，老公的一次出差归来，让怡敏抓住了余强对她不忠的证据。为平抚难耐的心绪，她给老公留下一纸便条独自去了厦门。在酒店由于她与来厦出差的钟孝良（董勇 饰）相互拿错了行李，钟孝良对她产生了兴趣，并对其发动爱的攻势，而怡敏也对这个细心体帖的男人产生了好感。交谈中，钟孝良坦露自已结婚多年，与妻子早没了昔日的激情，钟的坦诚是不言而喻的，怡敏陷入了深深的矛盾之中，最终她未能经的起异性的诱惑，与钟发生了一夜情。回到北京后，余强承认了自已曾经的不忠，怡敏听后无言以对。一年后一个偶然的瞬间，怡敏发现了陪妻购物的钟孝良，一时间心中似打翻了五味瓶……郎卓为梦想恋人佳铃买了一套阳光充裕的房子，郎卓期盼有一天远去上海的佳铃能够重新回到自己的身边。然而，郎卓却与女大学生叶繁相遇了。同因寂寥而相处的两人产生了情感，但两人觉得这种没有誓言的情感似乎不是爱情，郎卓依旧对暗恋的佳铃无法释怀。佳铃的突然归来使这段萌芽的爱情无疾而终了，痛楚的叶繁离开了朗卓的生活，许下愿望哪怕倾囊所有也愿意去换取佳铃的位置，哪怕只有一天也好。故事发生在北平，叙述的是从1937年到1948年北平解放前夕两代人的生活经历。1937年，卢沟桥的炮声点燃了中华民族的抗日烽火，刚刚走出大学校的青年路童谣、赵大勇、吴霞等为挽救民族危亡和北平人民一齐投入抗日救亡的工作中。北平沦陷后，几个热血青年选择了不同的生活道路，童辛去了抗日前线；童谣结婚过着小日子；吴霞随家人到大后方避难。故事主要围绕三个看似互无关联的美国家庭展开，一个“看不见”的摄像师“扛着摄像机”记录他们生活中的点点滴滴。这三个家庭也很有代表性：一个是传统的美国中产阶级家庭，一个是老夫少妻的组合，一个是同性恋家庭。This personal experience made me have a deep feeling. This is not only a practice, but also a life experience and a precious wealth in my life. In the future, I will take part in more social practice, hone myself and let myself know more at the same time, so that I have experienced more aspects of society before stepping into society. As a contemporary college student, perhaps the real tribulations just pass us by and there is not too much entanglement. Most of us have always lived and studied in a comfortable environment. Many things are readily available, but in a distant corner, there are some people living a completely different life from ours. In the mountain village, in response to knowledge, the children showed hungry eyes. In response to life, farmers showed the spirit of fighting against the scorching sun and torrential rain. Who can not be shocked or moved? This time, when we walked into the mountain area, it was a single spark that could start a prairie fire. It is a spiritual collision, a kind of concern and a touch.1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.
