2020广州高考二模作文8篇汇总 2017广州高考二模作文及点评：独立使自己更加强大 有一位17岁的英国女孩买彩票，中了100万英镑后购买了两套 物业，吃喝不愁，但四年后她将彩票公司给起诉了，称彩票毁了自 己的生活，希望回到获奖前的生活。彩票公司最后聘请财务顾问为 她提供理财服务。我认为，如果该女孩从小能养成独立的习惯，那 么将不会面对突如其来的巨额奖金，手足无措，焦虑万分。 我们的人生并不是一帆风顺，我们的成长也并非风雨无阻，我们的父母也不可能永远呵护着我们，让我们生活在一个毫无困难的温 室中，我们总要面向社会，而在这之前，我们要成为一个独立自主 的人才能在这波涛汹涌的社会中不被淹没。如果这位英国女孩能够 独立自主，那么这100万大奖将不是烫手的芋头而是天降甘露。让 她能更加舒适的生活下去，将这些钱合理分配自主的进行合理利用 和投资生活得轻松而有条理。 独立有利于我们的学习，当我们在学习的过程中，总是会遇到许许多多的困难和问题，往往这个时候我们都是马上去问同学或老师，缺乏自主思考与自己亲自解决的过程，只是简单的会了一道题，而 不是通了一类题。导致效率十分低下，最终和他人的距离越拉越大。如果我们能够有自主学习的习惯，独立思考，那么将使自己更高效 率的有效学习。 独立有利于个人的成长，李嘉诚在创业初期在茶楼里当小工，但他在闲余的时间总能独立学习，自学了许多外语和为商之道。在开 塑胶厂时，常常都是亲力亲为，最终造就了一名地产大亨。如果我 们能够独立的生活，自己的事自己想办法搞定，将对我们以后的成 长和发展更加有利，当我们独立完成很多事后，将让我们变得自强，在以后面对困难时，不会像该获奖女孩一样倍感压力，手足无措， 而是能更好的独立解决问题，独立使我们的意志更加坚定，更加坚强，不会轻易被挫折所击败。

广州市2020年高三第二次模拟考试 英语 第二部分阅读理解(共两节，满分40分) 第一节(共15小题；每小题2分，满分30分) 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 WENQIANG A We can all think of times when people didn't make remembering easy. Directions given at machine-gun speed. New people introduced in a flood of names and handshakes. Whenever information is passed between people, it’s all too easy for it to go in one ear and straight out of the other. Thankfully, the opposite is also true. Look around you, and you’ll see parents who can get their children to rem ember exactly what they were told; advertisers who know how to imprint their sales messages on our brains. So, how do they do? Their secrets can be summed up in four simple words: focus, imagery, reasons and engagement. FOCUS means ensuring that the person you’re talking to can concentrate on learning. Choose your moment carefully. Check that they can properly hear or see the information. Communicate slowly and clearly enough for their memory to cope. IMAGERY helps information to stick. Do everything your can to make other people “see”the ideas you’re giving them. Add visual details to directions, and illustrate abstract concepts with metaphors. REASONS to remember help people to put in the mental effort. So, make it clear that your words are important, and be explicit about why. Maybe this information will save them time, protectthem from embarrassment, or let them enjoy a particular experience or event. EMGAGEMENT requires you to ask questions. Point out links between new concepts and things listeners already know. Activate their senses, spark their curiosity, get them doing something physical, or simply make them laugh. The next time you’ve got an important message to pass on, put some of these techniques to the test. You’ll discover that there are benefits on both sides when you know how to FIRE people’s memories into action. 21. What is the main purpose of the text? A.To report new research. B.To provide some advice. C.To explain a problem. D.To define some terms. 22. How can you do to help a listener “focus” on w hat you are saying? A.Select the appropriate time to raise the topic. B.Do something humorous to get their attention. C.Make sure the information provided is correct.

第二节书面表达 Sample 1: Dear Chris, Glad to learn that you will take part in a Chinese poem recitation contest. Here is my interpretation of the poem you’ll recite. The poem is about a son who is leaving his hometown to pursue his dream. Feeling concerned about his son, the mother decides to make a coat for him. She is worried that her son might not come home soon, so she sews every stich carefully hoping to make it last longer. This poem praises the love of mothers. In the first two lines, the characters “thread” and “coat” imply the inseparable bond between mother and son. In the l ast two lines, the poet compares a mother’s love to sunlight, which helps the grass grow day by day. And such great kindness cannot be easily repaid. Good luck in the upcoming contest! Looking forward to the news of your victory. Yours, Li Hua Sample 2: Dear Chris, Glad to hear that you’re participating in the Chinese poem recitation contest. The poem you chose is an ancient one, which ought to be a real challenge. The poem, written by Mengjiao, is called A Traveler’s Song. It’s about the deep love between the poet and his mother. The poem mainly describes a scene in which a mother is making clothes for her son who is leaving home to fulfil his dream. With each stich she makes, the mother conveys her deep love for her son and her concern that he may not return. The poet expresses his ideas using similes/comparison, concluding that a “mother’s love is like the sunshine to the grass”. With its rich emotion and depth, this poem is a good choice for your contest. Best of luck. Yours Li Hua

2020广州高考二模作文范文：人性化服务并 非理所当然 2020广州高考二模作文范文：人性化服务并非理所当然 英国一位17岁女孩获得了100万英镑大奖，领奖后她的生活无忧，当周围身边人都羡慕她时，她却觉得百万富豪的身份让她倍感压力，四年后，她起诉彩票公司，并希望能过回以前的生活，彩票公司最后聘请财务顾问为她提供财政服务，由此可见彩票公司的服务是周到的，是符合现代化的人性化服务。 我认为彩票公司的行为是一种负责任的行为，即使女孩起诉公司，公司最后还能为她提供理财服务，而不是斤斤计较，这种人性化服务在如今十分罕见，这难道不是我们应该推广的新型服务体系吗?或许有人会说，既然女孩都起诉公司了，公司就不应该再为她提供任何服务，并且公司应向女孩索取精神赔偿费用。但是，又换句话说，它仅仅只是一个17岁的未成年女孩，人生经验不足，不能正确处理好巨大金额的钱财，社会上应该多给予帮助，帮助她更好的理财，而不是挥霍。而彩票公司正是扮演了这样一个角色，少让政府操心。这样的做法正是我们应当推广并提倡的。 在中国，很多企业都宣称自己会有一条龙服务，但到最后，只要是他们觉得无利可图时便像踢皮球一样，什么都不归他们管，而在欧美等国，这种人性化服务是十分普遍的，他们是真正视顾客为上帝，努力帮助他们解决售后出现的问题。或许这也是为什么欧美国家的服务体系如此完善和周到。
当然，我们固然提倡人性化服务，但作为消费者本身也因或多或少，懂得如何解决问题，并不能理所当然的一味要求企业社会国家提供帮。一个17岁女孩，都是快要成年了，应该是懂得如何理财，而不是仗着自己有钱去起诉彩票公司，这是不理智的做法。也能体现出女孩不成熟的心智。倘若可以，为何不去请理财顾问呢，所以正因为企业了解女孩的心理，所以企业才没有计较过多，这种舍己为人的人性化服务才会诞生。 因此人性化服务并不是理所当然的，而是消费者与企业之间友好相处的产物。我们提倡人性化服务，但也希望消费者能有处理问题的意思，并非理所当然地接受企业提供的服务。 评语： 本文属于议论类二等文。 文章第一段引用材料，角度落在了彩票公司聘请财政顾问为女孩提供财政服务上，列出了观点：彩票公司的服务是周到的，是符合现代化的人性化服务。 紧接着在第二段中承接了第一段的观点，认为彩票公司的行为是一种负责任的行为，值得推广并提倡。第三段继续了第二段的思路，进一步拓展到对中国企业的服务方式上的讨论，并与欧美国家的服务体系进行了比较。第四段，利用女孩的不成熟褒扬了彩票公司舍己为人的人性化服务。结尾段回扣标题，点明人性化服务与消费者之间的并非理所当然的关系。 全文结构完整，思路清晰，层次分明。但是，对材料核心内容的理解有误。 人性化服务并非材料的核心内容，文章对材料进行了拓展理

应用文阅读 【解析】 本文是一篇应用文，介绍了Roger Williams动物园的活动、在动物园内应该注意什么、一旦迷路了要怎么做，还有在动物园可以做什么。 【解答】 （1）D 细节理解题。该题提问的是一个人怎样可以在动物园得到一件免费的T恤衫。根据题干中的关键信息“free T-shirt”可以将信息定位到Zoo Exhibit Game部分。根据该 部分中的最后两句“As you explore the zoo, check off all the endangered animals you discover from the list below. Find them all and win a free T-shirt.”可知，如果一个人能识别出所有的濒危动物，就可以得到一件免费的T恤衫。故选D。 （2）C 细节理解题。该题提问的是一个迷路的人应该去哪里寻求帮助。根据题干中的关键信息“a lost person”可以将信息定位到Lost Persons部分。根据该部分内容“If separated from your group, ask any zoo employee or security guard for immediate assistance or go directly to the Administration Building reception desk”可知，迷路的人可以到行政楼寻求帮助。故选C。 （3）B 细节理解题。该题提问的是下面哪一个行为在动物园是被允的。根据关键句可知，带相机是允许的。故选B。 2. I saw it first, Amy said, as she ripped the old leather wallet out of Charlies hands. Without saying a word, as if they both understood that this was a secret they didn’t want to share with anyone, they slipped into the alley, where no one could see them look inside. "There’s got to be a million dollars here!" Charlie blurted out, when they saw the pile of hundred-dollar bills. Amy, the more realistic of the two, did a quick estimate, thumbing through the wad of cash. “More like thousands,” she said, her voice shaking i n disbelief. They’d found the wallet in a flowerbed by the sidewalk, when Charlie dropped his cell phone while he was trying to talk and eat a slice of pepperoni pizza at the same time. Amy stuffed the wallet into her backpack and pulled Charlie along by his elbow toward her house. As they rushed toward Viceroy Avenue, they talked excitedly about what they could do with the money—buy gifts for parents and friends, get new clothes, travel to the rainforest in Costa Rica, and adopt a whale. It looked like all of their dreams would come true. For the last block, however, they didn’t talk. Each began to suspect that the other one was silently adding to the list of things they could buy. They finally reached Amy s house, but instead of going inside, they walked around the house to the back porch. They opened the wallet and counted the money into piles of ten. The total was $2,400—more money than either of them had ever seen. Then they both started talking at once. “I wonder who lost it.” Their moods shifted, sinki ng from the high of being rich for fifteen minutes to resigning themselves to what they must do next. For in the wallet’s clear plastic compartment, there was a driver’s license. They knew what they had to do. Although they would lose their newly-found treasure, in a way, they felt relieved. （1）Where did Amy and Charlie find the wallet? A.In an alley. B.In a backpack. C.Among some flowers. D.On the sidewalk． （2）In paragraph 2, why was Amy’s voice shaking?
