人教版高三英语二轮复习试题阅读理解Margaret Mead, the most famous anthropologist(人类学家)in the world, was born in the USA in 1901,the oldest of five children. Her father was a professor of finance and her mother was a sociologist. After studying psychology as an undergraduate, Mead began a PhD in the relatively new field of anthropology. Mead was particularly interested in primitive communities because she believed that such isolated cultures could serve as "laboratories" that would reveal ways of living that the modern world had forgotten about but needed to remember.Having travelled to Samon, a few tiny volcanic, tropical islands in the center of the Pacific Ocean, Mead gradually got interested in gender roles and discovered that modern societies are far more strict in this area than primitive ones. For example, Americans tend to think of men as productive, sensible, and aggressive, while women are often told they're more light-hearted, peaceful, and nurturing. But in her 1935 book, Sex and Temperament in Three Primitive Societies, Mead studied tribes in Papua New Guinea and recorded that in the Arapesh tribe, both men and women were peaceful and nurturing, while among the Mundugurnor tribe, men and women were both ruthless and aggressive.Mead's striking conclusion is that it isn't gender that makes women curl their hair or listen to people's feelings, or race that makes some nations regularly attack their neighbors. Rather, it's the social expectations and norms that have laid the groundwork for each individual's psychological makeup."We must recognize, "she reminded her readers, "that beneath the superficial(表面上的)classifications of sex and race, the same potentialities always exist, occurring again generation after generation, only to perish because society has no place for them."She is regarded as one of the most influential social scientists of the last century. People around the world mourned the death of Margaret Mead in 1978.A year later, the president of the United States, Jimmy Carter, honored the social scientist with America's highest award for civilians.1.What can we learn about Mead from the text?A.She was influenced by her mother to be an anthropologist.B.She majored in psychology and anthropology as an undergraduate.C.She believed isolated cultures could expose forgotten ways of living to the modern world. D.She discovered modern societies are less strict in gender roles than primitive ones.2.It can be inferred from Mead's study in tribes thatA.the world is filled with separate cultures.B.no gender characteristics are ever simply" human nature".C.knowing another culture will help us reflect on our own.D.social standards are responsible for individual's development.3.What does the underlined word "them" in the third paragraph refer to?A.Shared potential among humans.B.Classifications of gender and race.C.Social expectations and norms.D.Individual's psychological makeups.4.What's the passage mainly about?A.The difference between men and women.B.The recommendation of Mead's book.C.The introduction about a great anthropologist.D.The groundwork for each individual's makeup.七选五Apps such as WeChat and TikTok have gained popularity in recent years.1.Also TikTok is already a household name globally, maybe one of the Chinese brands to truly be recognized universally.WeChat is particularly relied upon as a secure part of the structure of our technologically advancing societies.2.Moreover, a court in Haidian allows litigants(诉讼当事人)to communicate with their lawyers through WeChat video connections.Many features of WeChat alongside its well-thought-out design has meant that the app has dominated its competitors domestically, especially during the disorderly origin years of 2012-13,when it was gaining traction.The ability to move through web pages without tags and save articles alongside other offline content within the app simplified the online experience.3.This is a fantastic application designed to combine the comprehensive nature of the web experience with the simplistic convenience of mobile apps.4.An example is that, instead of a loading white screen, users, when opening a PW A app such as WeChat, will simply at first see the content that had been previously browsing, allowing them to pick up where they left off, much like reading a book.The intuitive(直观的)design is what makes WeChat not just an app in communicating with friends and family. 5.You can also order a taxi through it.

全国新高考2024届高三一轮复习刷题卷语文试题及答案

全国新高考2024届高三一轮复习刷题卷语文试题及答案一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1—5题。
材料一:从春秋末期到战国时代,孔子仅仅是一个夫子。
夫子是什么呢?一个老师。
当时他的影响不是很大。
到了汉代,“罢黜百家,独尊儒术”,地位提高了;从汉到唐略有提高,唐代给孔子封了个“文宣王”;到了宋代,在文宣王前面加了“至圣”二字;到了元朝,地位有所下降;到了明朝,叫“至圣先师”;到了清朝,把历代称赞孔子的最好称呼全集中起来了:“大成至圣文宣先师孔子”。
可是好景不长,五四运动打倒孔家店,又到谷底了。
而今天,是个直线上升的状态,孔子的学说在今天受到很多人的尊重和推崇。
今天为什么这么多人学国学、学孔子、学《论语》?其实主要原因是目前处于社会转型时期,主流价值观不是很明显,甚至变化幅度非常之大,所以人们自然而然地转向我们古老的智慧,去寻求一种能够持久地指导我们心灵和行为规范的东西,孔子可以说是中国人的行为举止、价值体系的总设计师。
今天的祭孔和过去的祭孔不同,往昔祭孔是希望孔子的光环能造就一个礼乐并举的盛世,而今天的祭孔是要弘扬儒学中理想的道德观、秩序化的社会和谐观,以及礼与仁相为表里的教育观。
今天我们不会将孔子重新罩上神的外衣,对孔子最准确的评价是:他是一位伟大的往哲。
现在国学虽然比较热,但是公众对它的接受程度还是比较低,它是一个小众化的东西。
我们要把国学更好地继承下去,让它变成一个大众化的东西,而不仅仅是局限于文化人之间的讨论。
中国过去的封建社会,科举考试是动员了全国所有的知识分子专注地研究这一门学问,从幼儿就开始,到最后功成名就。
这样的时代和条件已不复存在了,所以我们对儒学的教育方法,如果采取过去那种方式,我认为是愚不可及的。
除去功利心,反而可以真正返本归元地继承我们祖先的文化精髓。
时代在前进,文化在发展。
我们面临的是一个大的转型时代,这个转型不仅包括社会制度,也包含科技的研究。

2024届新高考高三一轮复习语文试题卷含答案解析
2024届新高考高三一轮复习语文试题卷含答案解析一、现代文阅读(35分)(一)现代文阅读(本题共5小题,19分)阅读下面的文字,完成下面小题。
元宇宙的概念源于国外的科幻小说和科幻电影,其思想源头最早可追溯到1981年科幻小说作家弗诺·文奇教授的代表作《真名实姓》,小说中黑客们可通过脑机接口将其意识映射进虚拟网络世界。
1992年,尼尔·斯蒂芬森在小说《雪崩》中创造了一种和物理社会紧密联系的三维数字空间——Metaverse,现实世界中地理位置彼此隔绝的人们可以通过各自的“化身”(Avatar)进行交流娱乐,元宇宙“Metaverse”和数字化身“Avatar”的概念就此诞生。
21世纪以来,科幻电影中不断出现的机器人、梦境交互、VR游戏等场景丰富着人们对元宇宙的认知和想象。
直到2021年,随着元宇宙第一股Roblox上市,字节跳动、脸书、百度等科技巨头纷纷发布元宇宙战略,彻底引燃元宇宙热度,2021年也被称为元宇宙元年。
目前来看,元宇宙作为综合大数据、数字孪生、区块链、人工智能、通信、交互等一系列DICT技术的集大成者,将同时影响作用于科技、经济、社会等多个纬度,因此不同领域对于元宇宙的认知及观点也各有侧重。
目前业内针对元宇宙尚未形成公认定义,但对于元宇宙关键特征的认知基本形成共识。
形成以下六大核心特征。
全方位的沉浸体验:沉浸体验是衡量下一代人机交互性能的重要指标,元宇宙的沉浸感,不仅是传统3D图像空间或故事世界的沉浸感,更多的是社交沉浸感以及基于此而激发互动和创造内容的沉浸感。
数字孪生与数字原生:元宇宙可以映射物理世界、可以基于物理世界混合改造,即通过数字孪生,综合运用感知、计算、建模等信息技术,感知物理空间全要素数据,完成多穴度高精度3D建模及驱动渲染,实现物理空间与虚拟空间的虚实交互,塑造描述、诊断、预测、决策智能认知全过程,构建元宇宙虚拟世界。
元宇宙也可以塑造一个独立于物理世界的数字空间,即数字原生,用于在数字空间中探索特有的生活方式和社交体验。

(2)当带电粒子第4次通过虚线时,求粒子距O点的距离和粒子经历的时间。 参考答案 1. D 【解析】该图线描述的是质点离出发点越远,速度越来越小的的运动,不是匀加速直线运动,A错误,其斜率不是Δv/Δt,因此斜率大小不等于加速度大小,B才错误;四边形BB′C′C面积大小表示纵轴和横轴乘积表示的物理量时间大小,C错误,D正确。 考点:本题考查对运动图像的理解。 2.D 【解析】 试题分析:正粒子进入磁场时,磁场垂直平面向里,运动轨迹的圆心在y轴上,由于只有第一象限才有磁场,所以粒子圆周运动不能进入第二象限,否则会离开磁场做匀速圆周运动,
而且在前02T和后02T都不能进入第二象限,那么根据对称性,末速度方向仍为水平向右,粒
子要想在t=T0时距x轴最远,后02T的运动轨迹与y轴相切,如下图所示。根据下图几何关系可知,02T时间内圆周运动转过的圆心角为566,设圆周运动周期为T,
则有05622TT,即065TT,根据带电粒子在匀强磁场中做圆周运动的周期2mTqB,可得053mBTq,对照选项D对。
考点:带电粒子在匀强磁场中的运动 3.C 【解析】 试题分析:A点释放后,在AB端点电荷的合电场作用下,电场力做正功,电势能减少,当合场强方向与运动路径垂直,即与半径共线时,电场力不再做正功,此后开始做负功,所以合场强与半径共线时即是电势能最小的P点。电场合成如下图,根据几何关系有22221(sin)8tan(cos)(tan)BAB
