Watching a big city likeLondongradually turn dark and darker into the night is a beautiful journey of time and light. So how about taking a historical evening walk and touchingsome of the nicest areas in centralLondon? Let’s get started.6:30 pmThe walk starts on theMillenniumBridge. On the bridge, watch the scenic city across the River Thames with the skyscrapers gradually lighting up against the darkening skies.TheMillenniumBridgehas been featured in many London-based films, includingHarry Potter, and the filmGuardians of the Galaxy.7:30 pmIt’s getting dark. A fifteen-minute walk northwest fromSt Paul’s Cathedral takes you to the historic Borough Market. During the evenings, you find a lot of restaurants around the market. This is an excellent time to get your dinner.9:00 pmThe next stop isLondonBridge. This is about 6 minutes’ walk from the Borough Market. As you join other onlookers and mentally go through the nursery school rhyme of “LondonBridgeis Falling Down”, you get lost again in history. Why does the song sayLondonBridgeis falling and who is the fair lady?During theLondoncity fire of 1897,LondonBridgeserved an important role in fire control. It was one of the major structures that prevented the fire from crossing over to the other side ofLondon.11:30 pmLondonnever sleeps; it’s a few minutes to midnight and everywhere is still filled with people moving around. About four minutes away from the Golden Jubilee Bridges isTrafalgar Square, our next stop.12:00 amIt’s been a beautiful evening, hasn’t it?1.

Comedian Caitlin Reilly used the app during quarantine (隔离) to make fun of those annoying coworkers for one of the top liked videos. And singer Curtis Roach made an song for the endless days at home with his song Bored in the House.The second most popular video was an Idaho man named Nathan Apodaca who shot to fame after coolly singing Dreams by Fleetwood Mac, while skateboarding on a highway.But the most liked TikTok video was awarded to Bella Poarch with 45 million followers, who created a simple but interesting video with a few seconds of well-timed head nods and eye rolls.While the app might be designed for youth, Chikumbu said that the growth of TikTok this year has pushed it more into mainstream culture. “You're seeing everyone from the teenager to the college students with their parents and then their grandparents all making videos,” said Chikumbu. “And now TikToktrulytranscendsgenerations, particularly in this year when people had a lot of time to dig in and not only watch, but try.”4.

Takes charge of.CThe cumulative rainfall in Henan province during the four days was the highest since the province has records, the provincial meteorological service said. The rain was heaviest in the provincial capital, Zhengzhou, for a short period on Monday and Tuesday. Northern, western and central parts of Henan also experienced downpours, the service said. Zhengzhou's biggest one-hour precipitation (降水量) —201.9 mmbetween 4 and 5 pm on Tuesday—was also the highest on the Chinese mainland. The previous record was 198.5 mmin the village of Linzhuang in Zhumadian in August 1975, the National Meteorological Center said. The city's precipitation duringthe four days exceeded that of its average annual precipitation, the center said.Chen Tao, chief forecaster at the National Meteorological Center, said abundant water vapor (水蒸气) brought by Typhoon In-Fa and the province's special geographical features led to Henan's rain. “Partly affected by the typhoon, large amounts of water vapor have been transported to China's inland areas, including Henan,” he said.From Thursday to Monday, rain was forecast to continue in Henan. However, rainfall will gradually subside in Zhengzhou and the province's northern and central regions, though the storms will increase the risk of mountaintorrents and other geological disasters. By Monday, lighter rain is forecast for parts of Henan, the provincial weather service said. However, local authorities are still urged to bevigilantand prepare to prevent or cope with flooding and other possible disasters.Predicting such weather events remains a challenge worldwide because it involves many meteorological phenomena, the center said. “The formation of this kind of extreme weather, including rainstorms and high temperatures, is complex,” Chen said. “We still lack effective solutions and methods for such forecasting”, he said. “We are now putting a lot of effort into tackling the difficulty. We believe that as the technology improves, we can better forecast the events.”8. What message does the author mainly want to convey in the first paragraph?A. heavy rain fell in Zhengzhou.B. The rain in Henan lasted four days.C. Zhumadian also suffered the similar heavy rain.D. Henan experienced the biggest rainfall of all time.9. What can be indicated from Chen Tao's words?A. It is not easy to forecast the extreme weather.B The rain of Henan is mainly caused by Typhoon In-Fa.C. The center hasn't put a lot of effort into solving the problem.D. Rainstorms and high temperatures can account for the heavy rain.10. What does the underlined word “vigilant” probably mean?A. Relaxed.B. Alert.C. Reluctant.D. Communicative.11. Where might the text be most probably taken from?A. history book.B. A novel.C. A news report.D. A science magazine.DChina's Mars probe Tianwen-1 successfully landed on the surface of the red planet on May 15, 2021, leaving a Chinese footprint on Mars for the first time and in its first attempt, becoming the only other nation besides theUSto get such an achievement. The Tianwen-1 probe touched down at its pre-selected landing area in the southern part of Utopia Planitia, a wide plain on Mars, at 7:18 a.m.(Beijing Time), after three months scanning the whole planet on Mars docking orbit, the China National Space Administration(CNSA) announced.Tianwen-1, including an orbiter, a lander and a rover, was launched from the 'Wenchang Spacecraft Launch Site on the coast of southernChinas islandprovinceofHainanon July 23, 2020.

According to the administration, the country's first Martian probe will conduct scientific investigations about the Martian soil, environment, atmosphere as well as water.China's planetary exploration program has been named “Tianwen”, which was named after a long poem by the famous ancient poet Qu Yuan. The name represents the Chinese nation's willpower in pursuing truth, the country's cultural inheritance of its understanding of nature and universe, as well as the unending exploration in science and technology.China's first Mars rover has been named “Zhurong”, which means the god of fire in an ancient Chinese story. The name indicates Chinese people's blessing for the rover to light the flame ofChina's planetary exploration. The rover has six wheels and four solar panels, and carries 13 scientific instruments. According to the CNSA, Zhurong has started its scientific exploration after moving from the landing platform onto the Red Planet's surface on May 22.More than 40 Mars missions have been launched since the 1960s, but only about half have succeeded. It is the first time in the world that orbiting, landing and roving on Mars has been completed in one launch mission, andChinahas come to the forefront of Mars exploration in the world.12. What can we learn from the first two paragraphs?A. China is the only nation to launch a probe to Mars.B. Tianwen-1 landed in the northern part of the planet.C. Tianwen-1 scanned the southern part of the planet.D. The Mars probe will carry out scientific investigations.13. How did the planetary exploration program get its name?A.

2020年三明市第十一中学高三语文三模试卷及答案解析

2020年三明市第十一中学高三语文三模试卷及答案解析一、现代文阅读(36分)(一)现代文阅读I(9分)阅读下面的文字,完成下面小题。

放电影胡永标①太阳热烘烘地照亮了放映员家的小院子。

从客厅出来,放映员看见一个汉子在院门口怯怯地探了探头,想进来又不敢进来。

放映员问:“你找哪个?”汉子说:“你是放映员吧。

”放映员点点头。

汉子说:“我是高云山人,想请你去我们那里放场电影。

”②高云山是乡里最偏僻最贫困的一个小村庄,放映员没去过,一般的人都不会去那穷山沟。

放映员看了汉子一眼,发现他黝黑的脸上爬满了汗珠,身上的红背心也湿嗒嗒的。

放映员说:“那地方太远了,又没电,我不想去。

”汉子眼里的光暗淡了一下,急急地从裤兜里掏出一盒压扁了的“大前门”香烟,笨拙地抽出一根递给放映员,脸上带着笑,说“你就去一趟吧,求你了。

”放映员沉吟了一会儿说:“山高路远的,还要扛柴油发电机去,多麻烦。

”汉子的眼睛亮了,说:“我来扛!”③放映员又说:“要去可以,不过要多加钱。

”汉子低头咬咬牙,说:“你开个价吧。

”放映员就说了一个数。

汉子点了点头,说可以。

放映员的腿脚不方便,是多年以前跌下山崖弄伤的,走路一瘸一拐,所以他几乎不去偏远山区放电影。

现在见汉子从大老远来了而且态度诚恳,不去就有点对不住人家了。

于是叫来读高中放暑假在家的儿子一同去。

④放映员走路不方便,柴油发电机由儿子和汉子抬着,他挑着银幕、电线和影片。

一路上蹚水过桥上山下坡,走了四个多小时才到汉子所说的高云山。

太阳西沉百鸟归巢,高云山四面环山,是个十来户人家的小村庄,站在山上看,整个村子像一口锅一样被云雾罩着。

听说放电影的来了,村里人像过年一样高兴,老老少少呼啦一声围拢上来,似乎他们从来就没看过电影。

⑤一般村里放免费电影都在晒谷场,可这回却在祠堂门口的一小块空地上。

挂好银幕收拾妥当,天就黑了下来。

汉子始终在放映员身边,随时等着放映员的吩咐,倒茶递烟忙个不停。

祠堂门口亮堂堂一片,夏夜的飞虫围着灯泡打圈圈,银幕面前坐满了闹哄哄的村民。

县城的人们能轻易地给他画一幅肖像:五短身材,大眼粗眉,大檐帽永远端正,墨绿军衣颜色早褪,全身满缀着四十多枚明晃晃的毛主席像章。

他总是推着一辆吱呀作响的红旗牌28自行车,车后贴着三块写满毛主席语录的纸板,车前挂着一张脸盆大小的毛主席画像——画像被老人当作了车牌。

县城里的人大多能清晰地回忆起他的声音:洪亮,亢奋。

激动时,他会咧开干裂的大嘴,露出两排蛮横而不齐整的黄牙,双手像杨树枝一样摇摆。

30年来,李德才如布道师一般,不厌其烦地寻觅着人群最密集处,开启他激昂而冗长的演讲。

演讲的内容只有一个:红色语录。

政府大院前,他对着来来往往的公务员高呼:“只有落后的领导,没有落后的群众!”体育场里,他跑着步,一遍遍地大喊:“发展体育运动,增强人民体质!”田畔地头,他笑着热情鼓励田里的农民:“备战备荒为人民!”就连在街头有人打架,他也会冲上前,拦下两人,正经严肃地表示:“要文斗,不要武斗……”更多的时候,人们会看见李德才站在县政府门口,针砭时弊,指点江山。

这位年过七旬的老人仍怀抱着坚硬的革命情怀,并试图影响他人。

有时,他也会得意自夸:“马克思的博才,毛泽东的天才,刘少奇的文才,周恩来的人才,张春桥的口才,都不如阳高的李德才!”小城里的人很早就窃窃私语,说李德才“精神有毛病”“学毛主席语录走火入魔了”“陷在旧时代里出不来了”……平日里的李德才和善、勤快,言语清晰,种菜为生,他卖菜羞于与人讲价,遇见老人还免费赠送,这让他仅能勉强维持温饱;农闲之时,他常推着个小推车走街串巷,收捡人们丢弃的毛主席像章或其他“文革”遗物,最终收集了一两百个像章,装满一个小布袋。

郴州邮政营销环境与企业优劣势分析报告•郴州邮政营销环境分析营销环境的变化关系着企业的生存和发展,从中,邮政企业应有所启发,在经营发展过程中,不能埋头赶路,还应抬头看天,重视企业营销环境的分析,规避环境中的威胁,挖掘环境中潜藏的机会,推动新一轮邮政大发展。

所谓出门要问路,入乡要随俗。

在市场经济条件下,在激烈的市场竞争中,重视邮政新技术应用、邮政业务更新、国家大政方针对邮政的影响、业务资费及人行转存款利率的调整等营销环境的分析,能使我们在经营策划和市场竞争中掌握更多的主动权,能使邮政事业健康、稳定地发展。

营销环境分析有宏观和微观两个方面。

宏观上,邮政作为社会的基础设施,与社会的政治、法律、经济、文化、资源、技术等有着密切的关系。

尽管这些都是邮政企业的不可控因素,但分析其变化、预测其走向,充分利用好政策,关系着邮政的发展规划和战略决策。

微观营销环境的分析,包括行业结构和竞争对手分析等,尤其是用户需求、替代产品的分析直接关系着企业的经营效益。

可以说,用户永远是企业设计产品、制定营销策略的根本出发点。

不考虑用户差异,如心理差异、消费行为差异、经济状况差异等,邮政新业务开发就注定是无源之水、无本之木,企业就要走弯路,甚至遭受经济损失。

而各种替代产品的存在和发展正在分流邮政业务,直接损害着邮政企业的经济效益。

如函件正被电话、传真等信息技术分流;储汇业务正被专业化银行的便捷服务分流;报刊发行正被电视、互联网及自办发行分流。

面对这样的变化和动向,邮政企业应分析内外动因,掌握变化规律,进行业务预测,整合资源优势,采取多元化经营,扩大服务范围,向用户提供宽松的用邮选择空间,从而增强自身竞争力,以赢得用户和市场。

营销环境因素经常处于不断的发展变化之中,这使得营销环境分析不能一劳永逸。

尤其是随着经济全球化进程的日益加快,我国服务贸易市场对外放开程度的加强,跨国公司将大举进军中国邮政市场,邮政企业将处于一个范围更广、影响因素更多的世界大环境中,营销环境分析难度会更大。

邮政各级企业必须熟练掌握适应环境的有效途径和方法,加强营销环境的分析,才能使自己在市场中永远处于有利的地位,在各种形式的竞争中立于不败之地。

郴州邮政优劣势分析(一)优势分析1.多年来一直出于国内快递企业龙头老大位置的EMS依赖于邮政的专有优势,经过多年的经营,拥有了一个非常庞大的邮路网络;2.拥有专职员工的队伍尤其是多年经营布局的人员和用于快递的专用投递、运输机动车辆;3.与世界上200多个国家和地区建立了业务关系,在国内的众多城市都开办了业务,网点普遍;4.建设了计算机跟踪查询网络,方便业务运行状态的查询;5.开通了中国邮政航空快速网,拥有了自己的快递专机,为EMS航空快递提供了很好的基础设施;6.中国邮政快递网得到进一步提速,依赖其高速公路汽车网,相继开通了“全夜航”、开办了“次晨达”、并推出了“次日递”和“限时达”等业务,并在国内开始提供包裹快递服务。

在快递市场中不断成长起来的民航快递(CAE)和中铁快运(CRE)也显示了相当的活力,在其运输网络所覆盖的城市间开办全国性的快递服务,借助航空和铁路的网络系统优势分别实现快件的及时送达和联运快件业务。

民营快递企业有着相对比较低廉的价格,相对灵活的服务和由此带来的较高的效率,这使得民营快递企业在竞争中有着自己的一席之地,产生了一批具有强竞争力的民营快递企业。

大田快递拥有一支由专业员工组成的队伍并配备先进的基础设备。

服务范围遍及全国541个城市。

快递服务逐渐多样化,由原来单一的标准服务发展到24/48小时的航空快递服务和72小时的陆路快递服务相结合。

宅急送快递运输网络由众多子公司、分公司和营业所等组成,网点已经遍布国内2--3级城市。

依靠中国航空货运网络,快运业务覆盖了中国800多个城市和地区,并开展“24小时全国门到门”快运服务。

(二)劣势分析1.在体制方面,EMS属于邮政系统,而邮政系统存在着政企不分的问题,管理上仍使用行政手段,企业没有完整的监督激励机制;2.在资金方面,尽管EMS有着国家的支持,但是与资金雄厚的国际快递公司相比还是稍逊一筹;3.在技术水平方面,EMS技术水平相对于国际快递公司来说比较落后,尽管其开始建立网络查询系统但是对邮件的监控程度比较差,有时会出现查询答复不及时、投递延误及邮件丢失的现象,引起广大客户的不满,影响其服务质量,并且EMS不能对在途包裹进行跟踪;4.在服务水平方面,EMS缺乏从客户的需求出发、不断开拓新的物流服务的能力。

而民营快递企业的规模都偏小,结构松散、信息技术比较落后,资金比较匮乏、人才短缺、员工素质较差、政策上存在限制。

快递服务不规范、服务范围比较狭窄、服务态度较差、推托责任、快递质量不保证、甚至丢失和损毁委托快件。

如宅急送,业务范围仅仅局限在快递,没有足够的信息技术支撑等。

另外,由于各种原因,包括EMS在内的大多数国内快递企业不能很好的利用自己所独有的网络资源优势,不能使之与提高客户服务水平相结合,造成网络维持成本过高,信息不畅,达不到对客户的要求快速及时的反应。

(三)机会分析随着世界经济的发展,世界各国的经贸往来日益频繁,跨国经济活动在不断增加,这使得国家与国家间的快递活动也呈上升趋势发展。

中国作为具有强劲发展势头的经济大国,与世界各国的贸易增多,带动了中国的快递业也迅速发展起来。

有资料显示,目前中国快递市场规模已超过200亿元,而且每年还在以超过30%的速度高速增长着,中国将是全球快递业增长最快的地区。

这说明中国国内的快递业将是一个十分巨大的市场。

这为国内快递企业经营中国国际快递业务提供了商机。

国际快递公司进入中国伊始,纷纷与国内快递企业合作,共同经营业务。

这也给国内快递企业经营中国国际快递业务提供了一个借鉴、积累经验并延伸扩展国际业务的机会。

国家一系列政策的出台为国内快递企业经营国际快递业务提供了政策支持方面的优势。

(四)威胁分析目前,中国国际快递市场上的快递业务基本上是由国际快递公司经营着。

以UPS、FedEX、DHL、TNT等为首的国际快递公司凭借本身先进的技术优势和经验优势占据了中国国际快递业务80%的市场份额。

有资料显示,这四家国际快递巨头的速递价格普遍低于中国EMS的10%—15%左右,这大大提高了他们的竞争力。

国内快递企业要想在中国国际快递业务中与他们分一杯羹不是易事,他们是国内快递企业最大的威胁条件。

UPS(联合包裹):UPS是一个提供广泛经营项目的公司,目标是“实现同步化商业”。

在中国业务总量的增长速度已连续几年保持在35%以上。

目前已在包括深圳、青岛、厦门、东莞、杭州、天津、石家庄、成都等20个城市设立代表处。

UPS具有一个强大的地面覆盖系统,这为它的地面运输提供了非常好的条件。

它的全球信息网拥有一个专用卫星和50万英里的通讯网络,能与全球1300个配送点随时联络,顾客还可以通过网络随时查到包裹所处的位置和状态。

网上查询包裹的投递情况完全透明,使得顾客对企业的信任感大大加强。

¬UPS将把上海建成亚太区的四个转运中心之一。

计划今后几年在中国投资5亿美元,部分资金将用于2007年在浦东国际机场建立转运中心。

FedEX(联邦快递):FedEX看准时机,致力于开拓中国市场。

凭借自身的空中力量和拥有600多架飞机的优势,成为占支配地位的机场对机场货物运输商,并拥有巨大的卡车运输系统。

现已在中国220个城市设有网点,计划在未来4-5年内,再新增100个服务城市。

联邦快递的航空网络也在不断的发展建设中。

目前,联邦快递在美国和亚洲之间已经成功地建立起一张无可匹敌的网络,直接而全面地进入整个亚洲市场。

FedEX设有服务于北京、上海及深圳机场的航班,并将在上海建设中国最大的快件处理中心。

¬FedEx历经三年谈判后,已签下广州新白云机场计划将广州建成FedEx亚太的最大转运中心。

DHL(敦豪):德国 DHL作为第一家进入中国的外资专业快递公司,以每年40%的平均增长率高速向前发展,在中国已经达到36%的市场占有率。

DHL是网络建设发展最快的国际速递公司,目前已在中国各主要城市设立了29家分公司和160个速递中心。

敦豪环球快递、丹沙海空运、德国邮政欧洲快递已经统一整合在DHL名下,并凭借其领先的“一站式”综合服务能力使其将成为全球最大的快递与物流公司。

整合之后的DHL不仅保持了国际航空快递领域的领先优势,更增强了提供货运和物流解决方案的实力,成为业界最具实力的领导者。

敦豪环球快递(DHL)宣布在香港将投资1.1亿美元,提前扩建香港转运中心。

TNT(天地快运):荷兰TNT快递公司在中国市场保持平均约23%的收入增长率和年均30%的业务增长速度。

2005年6月,宣布在上海开设中国总部。

TNT已经向中国1000个城市提供了快递业务,计划几年内扩展中国业务,将其在中国的分支机构增加到100家以上。

TNT宣布首次引入两架波音747-400ERF型全货机,执行中国来往欧洲的定期航线服务。

预计今年中国至欧洲的货运量较去年将增加约35%,运力突破1000吨。

TNT曾在中国推出“综合直接快递服务(IDE)”,为其成功的吸收大批高增值货源,最近又破例地将直邮、快递和物流三大业务整合在一起,大力发展汽车物流,争取在新一轮外资快递争夺中获得优势。

并于去年进驻北京空港物流基地,总投资1.2亿元,年处理能力将达13万件,预计年营业额达到2.3亿元。

(五)总结通过对中国国内快递企业自身和外部环境的SWOT分析,我们更清楚的看到国内快递企业和国际快递公司的差距。

在中国快递业这样一个全面开放的市场中,国际快递公司不仅仅满足于国际快递业务,更把触角延伸到国内快递市场,这对中国国内快递企业来说是一个不小的挑战。

中国国内快递业在保持国内快递市场份额的同时,加大对国际快递市场的进入是一个必然选择,从而全方面增强自己的竞争力,成为能够引领中国快递业的一代霸主。
