A farmer had some puppies(小狗)to sell.As he was putting up an advertisement on the edge of his yard,he felt a pull on his trousers.He looked down into the eyes of a little boy.
“Mister(先生),”he said,“I want to buy one of your puppies.”
“Well,”said the farmer.“These puppies come from fine parents and cost much money.”
The boy reached deep into his pocket,and then he pulled out a handful of change and held it up to the farmer.“I’ve got thirty-nine cents.Is that enough to take a look?”
“Sure,”said the farmer.And with that he called,“Here,Dolly!”
Dolly ran out from the doghouse followed by four little balls of fur.As the dogs made their way to the fence,the little boy noticed something else inside the doghouse.Slowly another little ball appeared.This one noticeably(明显地)smaller.It moved awkwardly(笨拙地)，doing its best to catch up with others.
“I want that one,”the little boy said,pointing to the smallest puppy.The farmer said,“Son,you don’t want that puppy.He will never be able to run and play with you like these other dogs would.”
With that,the little boy stepped back from the fence,reached down and began rolling up one leg of his trousers.In doing so,he showed a steel brace(支架)running down both sides of his leg and a specially made shoe.Looking back up at the farmer,he said,“You see,Sir,I don’t run too well myself,and he will need someone who understands.”

Temple of Heaven The Temple of Heaven is a Taoist temple in Beijing, the capital of China. The temple was constructed in the 14th century by Emperor Yongle of the Ming Dynasty as his personal temple, where he would pray for good harvest and to make up for the sins of his people. The temple's architecture is quite interesting ： Everything in the temple, which represents heaven, is circular whereas the ground levels, which represent the earth, are square.

This temple is all white with many artistic decorations and statues full of mirrors that create nice silvery/glittering reflections. Kinkaku-ji Kyoto is filled with beautiful shrines and temples, but none can be compared to the beauty of Kinkaku-ji. This Buddhist temple has gain a lot of fame recently and has become one of the most visited places in Japan. Whether you visit during the fall when there are red momiji leaves compared with the gold, in winter when the gold is topped with pure white snow, in spring with the cherry blossoms(樱花开放), or in summer allowing you to see the beautiful temple's golden reflection —there is never a bad time to visit this beautiful temple. Golden Temple The Golden Temple in Punjab, India is the most sacred shrine of Sikhism. For the Sikhs, the Golden Temple symbolizes endless freedom and spiritual independence. The site of the temple began with a small lake that was so peaceful that even Buddha came there to meditate （冥想）. Thousands of years later, Guru Nanak, the founder of Sikhism also lived and meditated by the lake. The temple itself is decorated with marble sculptures, gilded in gold and covered in precious stones. 1.If you're interested in meditation, you would like to go to . A.Kinkaku-ji B.Temple of Heaven C.Golden Temple D.Wat Rong Khun “White Temple ” 2.What do the four temples in the text have in common? A.They are all located in Asia. B. They are all Buddhist temples.

辽宁省沈阳市实验中学2019-2020学年高一下学期期中地理试题 考试时间：60分钟试题满分：100分 一、选择题（每题2分，共40题） 人口分布与自然条件社会经济条件等有着密切关系 1. 亚马孙河流域是世界人口分布稀疏地区，其主要影响因素是 A. 地形复杂 B. 气候湿热 C. 资源匮乏 D. 地处内陆 2. 巴西高原东部是南美洲人口相对密集地区，其主要影响因素是 ①气候适宜②文化单一③地势平坦④水力资源丰富 A. ①② B. ②④ C. ③④ D. ①③ 【答案】1. B 2. D 【解析】 试题分析： 【1题详解】 亚马逊河流域由于受热带雨林气候影响，终年高温多雨，闷热潮湿，且雨林茂密，故不利于人类生存，故人口分布稀疏。故选B。 【2题详解】 巴西高原东北沿海为沿海平原地区，由于纬度略高，则气候适宜，故适宜人类生存；而该地区为主要的移民地区，文化多样，水能资源与人口分布关系不大。故选D。 考点：本题考查世界区域地理。 点评：本题难度一般，学生只要掌握影响世界人口分布的主要原因，并能结合世界主要区域的自然地理环境进而分析人口稀疏区和相对稠密区的地理原因。 分析下表有关资料，完成下面小题。 国家日本巴基斯坦蒙古澳大利亚 面积/×104km237.8 79.6 156.6 768 人口/万人12500 14000 236 1766 人口密度/(人/km2) 331 176 1.5 2.3
3. 根据各国数据分析，下列叙述正确的是( ) A. 人口数量越少，经济越发达 B. 人口密度越大，经济越落后 C. 人口密度越大，经济越发达 D. 人口数量和密度不能决定经济发展水平高低 4. 影响人口分布的基本因素是( ) A. 自然因素 B. 开发历史的长短 C. 政治、经济因素 D. 人类生活方式和经济活动方式 【答案】3. D 4. A 【解析】 【3题详解】 分析给出的数据可知：人口数量少，经济未必发达，如蒙古；人口密度大，经济未必落后，如日本；人口密度越大，经济未必越发达，如巴基斯坦。人口数量和密度不能决定经济发展水平的高低。D正确，ABC错误。故选D。 【4题详解】 影响人口分布的最基本因素是自然环境因素。在自然环境因素差异的基础上，开发历史的长短、政治、经济因素、人类生活方式和经济活动方式在施加影响，A正确，BCD错误。故选A。【点睛】自然环境因素对人口分布影响： (1)气候：人口主要分布在温带和亚热带的湿润、半湿润地区。 (2)地形：人口主要分布在平原和丘陵地区，山区人口较为稀少。 (3)水资源：一般沿河、沿湖地区人口稠密。 (4)土壤：土壤的自然肥力、耕作性能、开发利用程度不同，因而影响人口分布。 (5)矿产：矿产资源的开发吸引人口聚集。 北京、上海不同时期外来常住人口年均增速百分比图，完成下面小题。
