南阳一中2023年秋期高三年级第三次月考地理试题一、选择题组(每小题1.5分,共40题)城市土地出让是指城市政府土地主管部门依法将城市土地的使用权出让给用地单位,是联系城市产业结构与空间结构的纽带。
土地出让空间区位选择与诸多社会经济因素有关,其中人口规模、经济发展水平对土地出让具有重要影响。
下图示意黄山市城市土地出让区位模式。
据此完成下面小题。
1.V区虽位于城市外围,但商业用地和住宅用地规模大,主要原因是()A.位于城市外围,土地租金廉价B.人口规模较市中心大,商业服务需求高C.中心城区环境差,商业服务外迁D.位于旅游景区,经济发展水平高2.黄山市城市用地的分布特点是()A.分布均衡,集聚程度较低B.住宅用地分布在近郊和旅游区C.集中度高,成多中心状态D.中心城区土地利用率较外围低【答案】1.D 2.C【解析】【1题详解】黄山市为旅游业发达的城市,V区可能为旅游区,虽然与市中心距离较远,但旅游业的发展使其土地租金并不廉价,A错误;V区位于城市外围,人口规模并不如市中心大,B错误;没有信息说明中心城区环境质量差,C错误;旅游业的发展带动了经济发展,该地经济发展水平高,商业和度假旅居型、疗养等服务业的发展,使得V区商业用地和住宅用地规模较大,D正确。
故选D。
【2题详解】据图及上题可知,黄山市三类用地区域位置差异较大,A错误;住宅用地主要集中于中心城区、重要旅游区附近,B错误;商业服务用地分布的热点区域主要集中于城市商业集聚区、大型公共设施和旅游景区周围、重要交通设施附近,因此,黄山市各类用地集中程度高,成多中心状态,C正确;中心城区土地利用率较外围高,D错误。
故选C。
【点睛】影响城市土地租金的因素有距离市中心的远近和交通通达度。
波兰首都华沙的工业园区逐步转型成为次级商务区(SBD),其与西南运输走廊(IBD)和主城区的中央商务区(CBD)共同构成华沙的经济增长极。

)1、某班同学从山脚下某一水平线上同时开始沿不同路线爬山,最后所有同学都陆续到达山顶上的平台。
则下列结论正确的是()A、体重相等的同学,克服重力做的功一定相等B、体重相同的同学,若爬山路径不同,重力对它们做的功不相等C、最后到达山顶的同学,克服重力做功的平均功率最小D、先到达山顶的同学,克服重力做功的平均功率最大1.A解析:所有同学爬山过程中,初末位置的高度差相等,都是由低处到高处,重力都做负功,即克服重力做功。
有与重力的功与路径无关,体重相等的同学,重力的功相等,克服重力的功相等。
选项A正确B错误;最先到达山顶的同学所用时间最短,但克服重力的功可能较小,平均功率不一定最大。
最后到达山顶的同学所用时间最长,但克服重力的功可能较大,平均功率不一定最小。
2、一蹦极运动员身系弹性蹦极绳从水面上方的高台下落,到最低点时距水面还有数米距离。
假定空气阻力可忽略,运动员可视为质点,下列说法正确的是()A、运动员到达最低点前重力势能始终减小B、蹦极绳张紧后的下落过程中,弹性力做负功,弹性势能增加C、蹦极过程中,运动员、地球和蹦极绳所组成的系统机械能守恒D、蹦极过程中,重力势能的改变与重力势能零点的选取有关2.ABC。
解析:不管选那个位置为重力势能参考面,运动员到达最低位置前高度总是减小的,因此重力势能一直是减小的。
绳紧张后,随着运动员的下降,绳伸长,对运动员作用向上的弹力,此力做负功,同时伸长量增大,弹性势能增加。
由于空气阻力可以忽略,蹦极过程中,对于运动员、地球、绳系统来说,只有重力与弹力做功,系统的机械能守恒。
重力势能与重力势能参考平面的选取有关,而重力势能的变化量则与此无关。
3、如图所示,质量不同的两物体通过轻绳相连,M >m,滑轮光滑且质量不计,轻绳的伸长不计,空气阻力不计。

(共15小题, 每小题2分,满分30分)AThere once was a very wealthy man who had made great achievement. He had more money than he could ever spend, and he was admired and looked up to by his neighbors. Still,he knew that something was missing in his life. He wasn't happy. All his life he had been striving(奋斗)for happiness, but he had never been able to find it.Then one day, he heard about a hidden temple in Nepal that had a special room that contained the secret of happiness. He immediately sold all that he owned and set out to find this hidden temple. After many years of searching and countless hardships he arrived there. He was tired and penniless, but he knew that none of that was important now because he had found the temple. He asked a wise, smiling monk(僧侣)if he could enter the special room. The monk agreed and showed him the stairs leading to the room. He climbed them with legs shaking with expectation and slowly opened the door. He stared into the room with sunlight streaming through the window and saw what he had come so far to find. There hanging on the wall was the secret of happiness. The man gazed at himself in the mirror and laughed.It is time that we all realized that we were the secret of our own happiness. Happiness is a choice that we can make.

Some have an even bigger reason一to stay calm or out of prison. But Back on My Feet puts recovering addicts and the homeless on the road to a brighter future, starting with a simple step; attending group runs three tunes a week.At 5:30 a.m. on a hot July day, Back on My Feet's Team Brooklyn gathered in a parking lot. After a round of hugs and some warm-up, the group of eight volunteers and seven residents(居民)set out on a run to nearby Prospect Park. Some ran three miles, some longer, but the goal for all was to finish as a team"It's helping me put my life back together," said Jimmy, a 58-year-old cancer survivor who was homeless and a former alcohol addic t. “It’s healthy. It makes me feel good inside,” adds Jimmy.Many are skeptical(怀疑的)about the idea of homeless runners, according to Anne Mahlum, who founded Back on My Feet in 2007 after starting a running club for men at a shelter near her Philadelphia home. They did want to run, and in just six years, Mahlum's small running club has expanded to 10 cities around the country, and 388 active members.The only requirement for joining, besides wanting to, is insisting on at least 30 days."The first day we giv e them new shoes and Back on My Feet shirts," Mahlum says. “Then they run a mile the first day. And then gradually we'll encourage them to build goals. “After 30 days,residents gain access to services like financial aid,housing assistance and employment opportunities through Back on My Feet's partners. In its first year, the New York chapter has seen 41 members obtain employment, 34 gain housing and 50 work in job-training programs.That's not to say it's always easy. “I wanted to quit.

Chinese people are proud of the great food culture of China and some even praise the documentary by saying that “it is a best video that arouses our great love of our country”.Produced by Chen Xiaoqing, an award-winning documentar y maker, “A Bite of China” is filled with mouthwatering images of food ranging from royal cooking to local specialties. It focuses on the beautiful and simplified process of food making and attracts food lovers and ordinary audiences.“Television is filled with food these days, especially introductions by some professionalcooks, even famous TV hosts. We also have some scenes of food-making, but how to create dishes is only one aspect of food culture,” Chen says.“The program tries to bring something new b y presenting more cultural elements related to dishes, such as eating habits and eating principles,” he adds.Each series lasts 50 minutes. Every series will focus on different people, who will tell stories about their adventures with food. “A Bite of China” also focuses on social changes while presenting food cultures, such as the dispersion of families that leave the elderly in their hometowns while other members work outside. In such cases food serves as reminders of happy times and expectations of reunions.29. Which of the following statements is NOT true according to the passage?A. The documentary has many different characteristics.B. The documentary is not only about food making.C. The documentary usually lasts fifty minutes.D.

Although the controversial(有争议的)dish remains on the menu at most hotels, Green Beagle Environment Institute, a Beijing-based non-government organization that was the main sponsor of the survey, said the results are encouraging and reflect increased awareness.The survey was carried out in Beijing, Shenzhen and Fuzhou, which were selected as representative cities to collect basic data on shark fin consumption nationwide. In Beijing, 132 hotels completed the phone questionnaire between Nov. 20 and Dec. 12. Only 12 hotels, 9 percent, said they do not serve shark fin. A similar survey of 131 Beijing hotels conducted a year ago found only one hotel that did not serve shark fin, Wang Xue, chief coordinator(协调人)of the survey, said on Saturday.In Shenzhen, four out of the 85 four and five star hotelssurveyed had stopped serving shark fin, accounting for about 5 percent. In Fuzhou, only one of the 40 hotels surveyed did not serve shark fin. On average, about 6. 61 percent of the hotels in the three cities did not serve the food.“The survey reminded us there is still a long way to go to remove shark fins from Chinese hotels and restaurants, but the improved situation in Beijing is encouraging,” said Wang. “We found more hotels and restaurants were willing to take action over the past year.” International hotels are more active in the “shark-fin-free” project, she noted. China is the world's biggest importer and consumer of shark fin, which has been used in luxurious Chinese dishes for 500 years. Dishes made from shark fin are still regarded as a symbol of honor and respect,especially at business dinners, according to Wang.Research has also found that shark fin contains poisonous elements, but the nutritious value is less than that of chicken or pork. “We hope hotels and restaurants remove shark fin products from their menus,” Wang added.32. Why do Chinese people are fond of eating shark fin?A. Shark fin is rich in a variety of nutritionB. Shark fin stands for honor and respect in ChinaC. The living standard of Chinese is much better than before.D. Shark fin can make people live longer.33. In which way was the survey carried out?A . Phone questionnaire. B. Interviewing on the spot.C. Filling the forms.D. Talk show.34. According to the text, which city did the best this year?A. ShanghaiB. ShenzhenC. BeijingD. Fuzhou35. The author wants to tell us .A. the opinions divided on consuming shark finB. Chinese people' taste of shark finC. the world's biggest importer and consumer of shark finD. the appeal to hotels and restaurants for stopping serving shark fin第二节(共5小题; 每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
