单元综合检测(四)Ⅰ.阅读理解(共15小题;每小题2.5分,满分37.5分)AIn the summer of 1936,Jesse Owens joined the best athletes from fifty nations to compete in the Berlin Olympic Games.Until then,very few black athletes had competed in the Olympics for the United States.Owens was proud to be on the team.He was very sure of his ability.Owens spent one week competing in four different Olympic track and field events.And he won four gold medals in all four of the competitions.In the 100-meter run,he equaled the fastest time ever run in that Olympic event.In the long jump and the 200­meter run,he set new Olympic records.And as part of a four­man team,he helped set a new world record for the 400­meter relay race.He was the first American in the history of Olympic track and field events to win four gold medals in single Olympics.Owens's Olympic triumphs made him a hero.He returned home to parade(游行) in New York and Columbus.Businessmen paid him for the right to use his name in their stores.No one,however,offered him a permanent(固定的) job.He worked at small jobs.He and his family saw good times and bad times.Poverty was not new to Owens.He was born into a poor family,but he was lucky that he entered a school where one white teacher,Charles Riley, took a special interest in him.He often brought the boy food and invited him to eat with his family.And every day before school,he taught Owens how to run like an athlete.Owens always remembered the teacher who helped change his life.In 1976,Gerald Ford awarded Jesse Owens the Presidential Medal of Freedom.This is the highest honor an American civilian(平民) can receive.Jesse Owens died of cancer in 1980,at the age of 67.【语篇解读】本文主要介绍了闻名运动员欧文斯在奥运竞赛中所取得的成果以及他在柏林奥运会前后的生活状况。

第三单元学业水平检测(测试时间:120分钟满分100分)一、论述类文本阅读(9分)阅读下面的文字,完成1~3题。

如果我们把目光放大到人类文明的宏大背景,寻求文明发展的轨迹,就会发现青花瓷展开的契机和过程,与16世纪中国与世界连接的时空巨变有着紧密联系。

16世纪,一边是白银货币化,货币经济需求日益增长,引发了整个社会的急剧变化;另一边是市场经济加速萌发,使得瓷业生产达到一个高峰,青花瓷由此得到了历史上前所未有的成长机遇。

嘉靖朝以后,伴随晚明社会变迁,人们的主流审美取向发生了由单色釉向彩色釉主体转化的改变。

明代景德镇青花瓷大量生产和流行,逐步取代了单色釉瓷市场的份额,占据了瓷器的主流地位。

而至万历时大批量生产,由海外市场所激发,东南沿海新的青花瓷窑址如雨后春笋般出现,形成了青花瓷遍及全国的实态。

青花瓷的空间发展轨迹说明,在文明成长过程中,青花瓷完成了从地方向大一统国家的扩展,其成长不仅是自身的纵向繁衍,还在对域外的横向传播中显现出强大的生命力,中华文明得到了域外的认识和交融发展。

在内外市场环境的互动作用下,青花瓷的展开,见证了世界进入一个全球化的时代。

从传播范围来说,青花瓷达于亚、非、欧、美各地;就从事贸易的商船而言,包括中国、葡萄牙、西班牙、荷兰、日本和东南亚各国船只。

从时间上看,16世纪是中西开始直接交往的世纪。

随中西的直接交往发生的是西传欧洲的享誉世界的瓷器交流。

迄今为止,学者普遍熟知青花瓷在日本、安南的大量仿制活动,也了解青花瓷传入欧洲后,促使意大利佛罗伦萨等地区大量仿造青花陶器的历程,更清楚地知道1710年德国迈森成功研制出瓷器。

但是,对于率先将青花瓷传入欧洲,开启了中国风的葡萄牙于17世纪初已产生了青花彩陶规模生产的事实,却鲜有了解——青花瓷出现在欧洲和美洲乃至世界各地人们的家庭餐桌上,替代了以往的银器、陶器和木器,这种事实本身就是史无前例的文明交流的革命。

知识与技术的传递与融通汇聚于这一过程中。

2022高中地理第三章大气的运动单元检测新人教版选择性必修第一册.docx

单元素养检测(三)(第三章)(90分钟100分)一、选择题(每小题3分,共45分)(2021 •浙江联考)饱和湿度是表示在一定温度下,单位体积空气中所能容纳的最大水汽量, 超过饱和湿度,水蒸气就会凝结变成水滴。

读不同气温时的饱和湿度图(图中“。

”数量的多少示意水汽含量的高低)。

完成1、2题。

10P 20*C 30"C1.下列叙述正确的是()A.随气温升高,饱和湿度变大B.随气温升高,水汽更易凝结C.随气温下降,降水概率变小D.随气温下降,水汽四散逃逸2.某冷锋过境时没有产生降水,其原因可能是()A.冷气团温度过低B.冷气团水汽含量少C.暖气团气压偏低D.暖气团水汽含量少【解析】1选A,2选D。

第1题,据图可以看出随气温升高,饱和湿度变大;随气温升高,空气湿度达到饱和需要的水汽更多,水汽更难凝结;随气温下降,空气更易达到饱和,利于水汽凝结,降水概率变大;随气温下降,空气更易达到饱和,原有水汽会凝结。

第2题,某冷锋过境时,暖气团被迫上升,随着气温下降,空气饱和湿度下降,但由于暖气团水汽含量少,空气仍未达到饱和, 因此难以出现降水。

下图为某年某月地面天气形势图。

读图,完成3、4题。

3.从天气的角度考虑,此日下列各地最适宜人们骑车出行的是()A.乌鲁木齐B.兰州C.哈尔滨D.沈阳4.假设图中两锋面移动速度约为300千米/天,则未来两天,天气变化最接近的两个城市是()A.兰州、广州B.广州、西安C.南昌、台北D.南昌、西安【解析】3选C,4选B。

第3题,根据等压线的疏密关系判断此日哈尔滨风力最小,故相比较最适宜骑车出行。

第4题,图中两锋面为冷锋,且锋面移动速度为300千米/天,选项各城市中,广州和西安都位于锋前,未来两天的天气变化最接近。

2019年7月27日,黑龙江省黑河市出现“断崖式”降温,人们纷纷穿起棉袄御寒,三伏天过出了初冬的感觉;同一天,位于长江与汉江交汇处的湖北省武汉市,酷热难熬,完全处于“烧烤”状态。

He was also the first artist to use his work to pass a 23 of equality and justice(正义) for all —24 for the "little guy". Charlie Chaplin's career and life made 25 the first global icon (偶像); his too-small hat, his too large shoes and his trademark moustache were instantly recognized by audiences from Chicago to China, from Iowa City to India. And they 26 are today. All of these make Charlie Chaplin the first citizen of our global village.Chaplin, a native of London, was born in 27 on April 16, 1889 to music hall performers.

【导与练】2016高考政治一轮复习 第三单元检测试题(含解析)新人教版必修4

第三单元检测试题(时间:45分钟满分:100分)编者选题表一、选择题(本大题共12小题,每小题4分,共48分)1.在探究“事物联系哲理”的课堂上,一位同学举例:在非洲东部的大草原上,生长着一种金合欢树,在它的周围,举腹蚁、天牛、介壳虫、长颈鹿形成一个复杂的关系网。

为了不让长颈鹿等大型食草动物吃金合欢树的叶子,一些美国生物学家在6棵树周围围起带电栅栏,10年后,那些受保护的树日渐枯萎死亡,而没有受到保护任由长颈鹿啃吃的树却依然长势良好。

以下判断正确的是( )A.事例反映具体事物的联系不因人类活动而改变,切合课题B.事例反映事物之间联系的普遍性和客观性,切合课题C.事例反映任何两个事物之间都存在联系,切合课题D.事例反映自在事物的联系优于人为事物的联系,切合课题解析:B A项否认了人类对具体事物的影响,观点错误;C项否认了联系的条件性,观点错误;联系无所谓好坏,D项错误。

B项观点正确切题。

2.我国科学家利用现代生物技术,将外源抗虫基因——BT基因导入棉花植株,培育出转基因抗虫棉,使虫害得到有效控制。

但有专家称,此举有可能造成“基因污染”,危害人类健康。

这说明( )①事物之间的联系是多种多样的②应该一分为二地看待事物③次要矛盾会影响主要矛盾的发展和解决④矛盾是人为创造的A.①②B.②③C.②④D.①④解析:A 抗虫基因植入后既可抗虫又可能导致“基因污染”,这既体现了事物之间联系的多样性,又说明我们看待事物时要坚持一分为二的观点,①②符合题意;材料主旨是强调一分为二地看待转基因产品,③不符合题意;④的说法错误,矛盾具有客观性,不是人为创造的。

3.一口钟,无论敲哪一边,它总是整体作响。

人们只知道钟声洪亮、悠长,从来也不在意敲的是哪一边。

经常被敲的那一边就不服气,它总想告诉世人,主人敲的是我,是我在响。

为了证明这一点,在一个晚上它努力挣碎了钟体,让其他三面都落在地上,只有它仍悬挂着,它想让人们听到它的声音。

2024_2025学年新教材高中地理第三章地球上的水单元测试含解析新人教版必修1

2024_2025学年新教材高中地理第三章地球上的水单元测试含解析新人教版必修1

单元素养评价(三)(第三章)(90分钟100分)(70分)一、选择题(每小题2分,共40分)下图是“某城市建设前后水量平衡示意图”,读图回答1、2题。

1.城市建设导致当地( )A.地下水位上升B.地面径流汇合速度减慢C.蒸发量增加D.汛期洪峰流量加大2.城市建设后地面径流发生改变的主要缘由是( )A.生活用水量增加B.植被覆盖率增加C.降水下渗量削减D.城市热岛效应【解析】1选D,2选C。

第1题,由城市建设前后水量平衡示意图中各要素对比分析可知,城市建设使地下径流削减了18%,地面径流增加了33%,蒸发量削减了15%,故降水后,大量雨水快速汇合到河流中,从而导致汛期洪峰流量加大。

故选D。

第2题,城市建设必定会导致地面硬化面积增加,从而使雨水下渗削减,则地下径流削减,地表径流增加。

山东半岛某入海河流流域在1952~2009年修建了大量水库,实施大面积坡耕地改梯田和拦河闸坝修建,大规模林地、园地建设等,但该河流输入海洋的泥沙受其影响不大。

下图示意1952~2009年该河入海年径流量(108 m3),输沙量(104 t)累积折线(图中数据为河口水文站监测资料)。

据此完成3~5题。

3.对该河年输沙量造成影响较大的人类活动是( )A.坡地改梯田B.种植苹果树C.种植夏玉米D.上游修水库4.图中某项人类活动对该河流输沙量影响微小,其缘由可能是( )A.腾库容为了防灾B.涵养水源为主C.水库拦截粗沙为主D.建设的规模较小5.该河在1952~2009年,年入海泥沙量( )A.先增大后减小B.持续增大C.先减小后增大D.持续减小【解析】3选A,4选C,5选D。

第3题,读图可知,水库修建后,累积径流量和累积输沙量改变趋势差异不大,坡地改梯田和拦河闸坝修建以后,累积径流量和累积输沙量的比例关系折线斜度明显减小,且削减角度明显大于园地、林地建设后削减的斜度。

结合选项可知,坡地改梯田对该河年输沙量造成影响较大。

第4题,水库修建对该河流输沙量影响微小,其缘由可能是水库主要拦截粗沙,细沙悬浮于水中流向下游,粗沙若没有水库拦截,在流向下游的过程中,地势变得缓和,水流速度减缓时,仍旧会沉积下来。

5.“存在就是被感知”与“理生万物”体现的是同一哲学思想。

( )点拨:F “存在就是被感知”体现的是主观唯心主义思想,“理生万物”体现的是客观唯心主义思想。

6.唯物主义是无产阶级科学的世界观和方法论,是指导我们认识世界和改造世界的强大思想武器。

( )点拨:F 古代朴素唯物主义和近代形而上学唯物主义也都有其自身的局限性,只有辩证唯物主义和历史唯物主义才是科学的世界观和方法论,是指导我们认识世界和改造世界的强大思想武器。

二、选择题(每小题4分,共48分)7.(2017·金华十校模拟)下列选项与“未有这事,先有这理”观点相一致的是( )A.我思故我在B.世界是一团永恒的活火C.吾心即宇宙 D.世界是上帝创造的解析:选D “未有这事,先有这理”和“世界是上帝创造的”都是客观唯心主义,“我思故我在”是主观唯心主义,“世界是一团永恒的活火”是古代朴素唯物主义,“吾心即宇宙”是主观唯心主义。

故选D。

8.(2017·台州模拟)孟子和老子都是春秋战国时期我国著名的思想家,孟子提出了“万物皆备于我”的思想,老子提出了“道生一,一生二,二生三,三生万物”的思想。

这两种思想的共同点是( )A.都承认客观事物依赖于人的主观精神B.都承认客观精神是世界的主宰和本原C.都否认思维决定存在D.都否认存在决定思维解析:选B “万物皆备于我”的思想和“道生一,一生二,二生三,三生万物”的思想,两者都是客观唯心主义,故选B。

课时跟踪检测(一)Warming Up & Reading — Pre-reading阅读理解ASunshine OelfkeSunshine had been saving up to buy herself a bicycle, but she decided to break her piggy bank long before reaching her goal. As Sunshine began to load all the coins into her bag, her grandmother asked her what she was going to do with all of that money. Sunshine said she was using the coins to help her friend buy milk at lunch, something that her friend couldn't afford. Not satisfied to only give her friend milk for a day, she created a GoFundMe page to cover other children's milk for the full year.Jake and Max KleinWhen these 14­year­old twins were shut out of volunteer opportunities, they took matters into their own hands. It all started when the boys began cooking meals to serve the h omeless with a family friend in his home kitchen. “We asked him to take us with him to serve the meals, but when he looked into it, he was told, ‘No, they are simply too young,’” says Max. That's when they decided to start the Kids That Do Good site to allow young people to search for volunteer opportunities online.Gitanjali Rao11­year­old Gitanjali invented a device (装置) that can detect lead in drinking water in Flint, Michigan. She'd been watching her parents test their own water and shaking her head, as it were —there had to be better methods out there. No? Alright, well, then she'd invent one. Her three­part device could be the next big thing in water purification (净化), and help keep thousands healthy.Jackson Hinkle17­year­old Jackson has always bee n aware (知道的) of the problem of plastic pollution and its effects on ocean ecosystems (生态系统). He tried to raise awareness of water rights and support the creation of a clean future, and presently serves as founder and president of Team Zissou, an environmental club that has appeared in schools in California, Hawaii, and Washington. Jackson is also leading a campaign in his town called “Plastic Free SC”, which encourages the usage of reusable water bottles.语篇解读:本文是应用文。
