专题强化练(十三)自然地理第一组选择题仿真练(一)一、选择题(2019·衡水金卷四)下图是2019年10月22日某区域气压形势图(粗线),细线表示某地理事象的非等间距等值线,读图,完成1~3题。

1.推想图中乙地旁边的数值“125”表示的是()A.海拔高度B.风速C.降水量D.蒸发量2.图中甲地数值可能是()A.1 016 B.1 008C.1 024 D.293.图中势力最强的天气系统()A.中心降水量最大B.可能向东北方向移动C.中心位置可见烈日当头D.顶部气流呈逆时针方向辐散解析:第1题,图中的乙地旁边位于低压系统旁边,低压盛行上升气流,中心旁边降水量大,故数值“125”最可能是降水量,选C。

第2题,依据图中信息可知区域有上升气流,因此甲地应当处于低气压旁边,甲的数值应当是较小的那个数值,据此选B。

第3题,图中势力最强的天气系统位于乙地旁边,为低压系统,北半球的低压系统气流呈现逆时针方向移动,结合选项选B。

中心旁边降水量最大;中心位置盛行下沉气流,但不行能烈日当头,底部气流呈逆时针方向辐合,据此,A、C、D错。

答案:1.C 2.B 3.B(2019·银川一中模拟)巴丹吉林沙漠位于我国西北干旱半干旱地区,年降水量40~80 mm,蒸发量3 000 mm。

沙漠东南部腹地星罗棋布地点缀着常年有水的湖泊70多个,形成了世界上独一无二的高大沙山(海拔1 080~1 590m)环绕湖泊的景观。

苏木吉林湖就是其中之一,湖区全年降水量为163.6 mm,全年蒸发量1 261 mm。

下图示意苏木吉林湖区湖泊补给量和排泄量动态曲线。

据此完成4~6题。

高考地理大二轮复习 专题强化练(十一)原因措施类-人教版高三全册地理试题

高考地理大二轮复习 专题强化练(十一)原因措施类-人教版高三全册地理试题

专题强化练(十一) 原因措施类(限时25分钟)1.(2019某某某某调研)阅读图文材料,完成下列各题。

树木年轮(简称树轮,如图1所示)是树木在生长过程中受季节影响而形成的,一年产生一轮。

春夏季节,树木材质疏松,颜色较浅,称为早材;秋冬季节,树木材质紧密,颜色较深,称为晚材。

同一年的早材和晚材合称为一个年轮。

我国学者利用采自黄某某区冰川雪线高度以下的祁连圆柏树轮资料,重建了该地区河流过去近400年的径流变化。

祁连圆柏在0℃以下生长缓慢,该地区气候资料如图2所示。

研究表明,祁连圆柏树轮宽度与降水量呈正相关。

(1)【原因措施类】在分析祁连圆柏树轮时,以前一年10月到当年9月作为一个研究的时间段,而不是从1月到12月,试指出其原因。

(2)【原因措施类】分析夏季降水减少时,祁连圆柏树轮变窄甚至缺失的原因。

(3)【分析评价类】研究发现1657—1695年,祁连圆柏树轮间距持续增大,请推测该时段河流径流量的变化趋势并说明理由。

(4)【开放探讨类】祁连圆柏的寿命一般只有几十年到几百年,但我国学者却建立了该地区4 600多年的树轮宽度年表,试指出其研究方法。

(1)题,读材料可知,树木年轮是树木在生长过程中受季节影响而形成的,一年产生一轮。

祁连圆柏在0℃以下生长缓慢,所以祁连圆柏树轮以前一年10月到当年9月作为一个研究的时间段的原因是该区域10月下旬温度降到0℃以下,树木生长缓慢;从前一年10月到当年9月正好增加了一个年轮。

第(2)题,读材料可知,祁连圆柏树轮宽度与降水量呈正相关。

夏季降水减少时,树木缺少水分;气温较高,导致树木的蒸腾和土壤的蒸发强,该地位于半干旱地区,土壤水分不足,树木生长受限,故树轮变窄甚至缺失。

第(3)题,读材料可知,祁连圆柏树轮宽度与降水量呈正相关。

树轮间距持续增大说明降水增多,从而使河流径流量增大,所以河流径流量增大。

第(4)题,树木即使死亡,年轮也可保留。

按年代先后把活树的年轮序列与其之前地层中的树轮序列相衔接,即可得到很长时间的树轮宽度年表。

Monty Roberts owns a horse ranch(牧场).He has let me use his house to put on fund­raising events. The last time I was there he told me a story. It all goes back to a story about a young man who was the son of an itinerant horse trainer (巡回驯马师) who would go from stable to stable (马厩), race track to race track, farm to farm and ranch to ranch, training horses. As a result, the boy's high school career was continually interrupted. When he was a senior, he wrote a paper about what he wanted to be and do when he grew up.He wrote a seven­page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200­acre ranch, showing the location of all the buildings, the stables and the track. Then he drew a detailed floor plan for a 4,000­square­foot house that would sit on a 200­acre dream ranch.He put a great deal of his heart into the project and the next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, “See me after class.”Confused and disappointed, the boy with the dream went to see the teacher after class and asked, “Why did I receive an F?” The teacher said, “This is a n unrealistic dream for a young boy like you. You have no money. You come from a poor family. You have no resources. Owning a horse ranch requires a lot of money. You have to buy the land. You have to pay for the original breeding stock and later you'll ha ve to pay large stud fees. There's no way you could ever do it.” Then the teacher added, “If you rewrite this paper with a more realistic goal, I will reconsider your grade.”注意:1.续写词数应为150左右;2.请按如下格式在以下位置作答。

新教材2024届高考英语二轮专项分层特训卷第一部分专题强化练专题二阅读七选五强化训练十五逻辑推断法

强化训练十五逻辑推断法(A)In 2013, digital media consultant Baratunde Thurston launched an experiment. He decided to disconnect from his online life for twenty­five days: no Facebook, no Twitter, not even e­mail. He needed the break. __1__It didn't take him long to adjust to a disconnected life. By the end of that first week, he was less stressed about not knowing new things. __2__ He enjoyed food without Twittering the experience. But the end came too soon. After the twenty­five days, he had to restore his online presence.His experiment summarizes two important points about our relationship with social networks like Facebook and Twitter. The first point is that we increasingly recognize that these tools fragment (碎裂) our time and reduce our ability to concentrate. __3__ But the problem is especially serious if you're attempting to improve your ability to work deeply.To fight back against these distractions, Thurston felt his only option was to quit the Internet altogether. But the problem is that no one is meant to actually follow Thurston's lead.__4__ That is to accept our current distracted state as unavoidable. This brings me to the second point summarized by Thurston's story: it didn't take him long once the experiment ended to slide back into the fragmented state where he began.This rule proposes a third option: accepting that these tools might be vital to your success and happiness, but meanwhile accepting that most people should be using fewer such tools. I won't ask you, in other words, to quit the Internet altogether like Thurston did. __5__ There is a middle ground, and if you're to develop a deep work habit, you must fight to get there.A.He struck up conversations with strangers.B.It is a real problem for many different people.C.“I was burnt out, fried, and done,” he explained.D.This reality accounts for the remaining alternative.E.He had to return to the online world with books to market.F.But I'll ask you to reject the state of highly distracted connectedness.G.Fortunately, you will break the habit of surfing the Internet gradually.[答题区]1.________ 2.________ 3.________ 4.________ 5.________(B)Want a relaxing but fun challenge at home? __1__ Puzzles have been around for more than 250 years and the challenge of working out where each piece goes and carefully recreating the scene on the box lid can keep you busy for hours, days or even weeks.Puzzles come in a huge range of sizes and difficulty levels. For beginners, a 100­piece puzzle is usually a good starting point. __2__ Try grouping pieces with the same colours or designs because they will probably go in the same area oncethe puzzle takes shape.__3__ Those pieces are easier to find because they have a straightside. Stay patient as you search through and try to make it fit together. You maynot find any connecting pieces for ages but then several may suddenly appear.For a real test, puzzles that have 1,000 pieces or more are a tough taskand it's best to complete them with friends or family if you can. Choosing a scenethat interests you, such as a favourite film, sport or location, can help keep you interested and determined to work to the final piece. You can get fun educational puzzles, too. __4__Some of the best places to pick up puzzles are charity shops. They're oftenon sale for less than $5. Once you have completed a puzzle, it's nice to exchangeit with a friend. __5__ You just upload an image, such as a familyscene, and they will make a puzzle from it and post it to you. It makes a lovelyand unusual present.A.So others can have a go.B.You can't beat a good puzzle.C.Some companies make personalised puzzles.D.However, a good start doesn't always lead to a good result.E.Most people like to start by getting the four edges of a puzzle laid out.F.It can get you used to sorting out how the shapes, patterns and coloursgo together.G.For example, you may try a map of the world, historical timelines or theperiodic table.[答题区]1.________ 2.________ 3.________ 4.________ 5.________(C)The arrival of autumn has left me charmed once again by its generous harvestof pomegranates (石榴). While pomegranate juice had always been a favourite of mine,for a long time, I couldn't say the same for the actual fruit. __1__ How couldanyone possibly take pleasure in eating that? But by chance, I changed my mind.A handful of small pomegranate trees grow just outside the gate of myhusband's family home in rural Zhejiang. __2__ So one autumn, mymother­in­law gave me and my husband a bag filled with pomegranates she had pickedherself.At first, I rejected the seemingly burdensome pile of fruit on ourdinner table. __3__ He continued to bite on pomegranates and offerme a taste of the seeds, and eventually curiosity won. I popped a handful in my mouth,and found myself surprised in the best possible way.The seeds were filled with that familiar rich and sweet flavour. __4__ Moreover, it was superior to anything I had encountered in liquid form. Later,I'm always fascinated to discover the many locales in China also touched by the sweet pleasures of the pomegranate.__5__ At that time in my life, moving around left me toomuch stress, which usually left me with the discomfort of a nervous stomach. Butamong the many health benefits of the pomegranate is that it can naturally improve digestion. Regular consumption of the fruit had comforted my gut (肠道) so much. If you've yet to be addicted to the delights of the pomegranate, it's not too late to try.A.One taste turned me into a lifelong fan just like that.B.I had thought it's a bunch of soft and juicy little seeds.C.The branches are overhanging with the fruit every fall.D.My husband still attempted to persuade me to take a bite.E.It's the season's finest freshly­squeezed juice from the fruit.F.The healing properties of the fruit I experienced added to its charm.G.That was the same taste I had come to treasure about pomegranate juice.[答题区]1.________ 2.________ 3.________ 4.________ 5.________强化训练十五逻辑推断法(A)【语篇解读】本文是一篇说明文。

读图,完成1~2题。

1.图中R区域农业带的特点是()A.小麦与玉米轮作B.谷物与牧草轮作C.农产品产品率低D.生产过程简单粗放2.五大湖区少有大牧场放牧业的原因可能是()A.人多地少B.河湖众多C.需求较小D.缺乏饲草解析:第1题,结合学过的美国农业地域类型的分布可知,图中R区域为美国的混合农业区,是畜牧业和种植业的混合,实行谷物和牧草轮作,B对,A错;其农产品商品率较高,生产过程集约密集,C、D不对。

故B正确。

第2题,大牧场放牧业发展的条件是在地广人稀的区域,进行大规模生产,美国五大湖区属于传统工业区,人口多,城市密度较大,所以人多地少,不具备发展大牧场放牧业的条件,适合发展乳畜业,故A正确。

河湖众多不限制其发展大牧场放牧业;该地人口众多,市场需求量大;该地气候冷湿适合多汁牧草生长,不缺乏饲料;B、C、D 错。

故选A。

答案:1。

B 2.A(2020·肇庆一模)三七在我国已有千年药用历史,但只分布于我国西南地区北纬23.5°附近的狭窄地带,并且不耐阳、不耐旱、不耐湿。

地理二轮复习专题强化练十含解析

专题强化练(十)1.(2020·天津一中高三月考)阅读图文材料,完成下列各题。

材料2012年6月21日,我国正式公布在海南省建立三沙市,管辖西沙群岛、中沙群岛、南沙群岛的岛礁及其海域.珊瑚礁是由造礁珊瑚的石灰质遗骸和石灰质藻类堆积而成的一种礁石。

我国南沙群岛是南海上散布范围最广的珊瑚礁群。

南沙属热带、海洋性气候,高温、高湿、高盐、高日照、多台风、缺土地、缺淡水、缺土壤的“四高、一多、三缺"恶劣环境条件,南沙岛礁的特殊地理环境导致岛上驻守官兵长期存在“吃菜难”的问题.2010年5月,海军南沙部队蔬菜生产生活保障项目—-“南沙温室”建设正式启动。

(1)指出永兴岛的气候类型并分析其淡水资源缺乏的原因。

(2)分析南沙岛礁种植蔬菜的主要限制性自然条件.(3)针对当地的自然环境特征,分析在“南沙温室”建设中应注意哪些问题?解析:(1)永兴岛冬季主要受海陆热力性质差异的影响,盛行东北季风,夏季主要受气压带风带的季节移动的影响,盛行西南季风,所以属于热带季风气候.我国南沙群岛是南海上散布范围最广的珊瑚礁群,永兴岛是珊瑚岛,面积小;珊瑚礁是由造礁珊瑚的石灰质遗骸和石灰质藻类堆积而成的一种礁石,地势低平;四周环海,岛上无河流、湖泊,储存淡水的条件差,降落到地表的水大部分流入海洋中, 淡水资源缺乏。

(2)根据材料提示,南沙“三缺”:缺土地、缺淡水、缺土壤,所以南沙岛礁种植蔬菜的主要限制性自然因素就是这三个因素。

材料中分析,珊瑚岛岛礁是一种石灰质的岩石,不利于成土,缺少蔬菜生长所需要的土壤;由于四周是海洋,珊瑚岛岛屿面积小且石灰质岩石不利于储水,缺少淡水.(3)根据材料提示,南沙地处热带海洋环境,在减少温室过程中,应针对南沙多台风、风暴潮、波浪等海洋灾害;以及高温、高湿、高盐容易腐蚀物质的大气环境,要注意抗风、抗波浪、抗暴雨、抗腐蚀等问题。

答案:(1)气候类型:热带季风气候。

原因:永兴岛是珊瑚岛,面积小;地势低平;四周环海,岛上无河流、湖泊,储存淡水的条件差,降落到地表的水大部分流入海洋中。
