人教版（2024新版）七年级上册地理期中复习：第1~3章知识点提纲第一章地球第一节地球的字宙环境知识点一：宇宙1.概念：宇宙是时间和空间的统一体，是由各种形态的物质构成的。

2.天体类别：宇宙中有众多的天体，如恒星（巨大的气体球体，通过核聚变反应产生能量，发出光和热）、行星（本身不发光。

围绕恒星运行的天体）、卫星（绕行星或其他天体运行的天体，受到行星或其他天体的引力束缚。

）、星云等。

3.天体系统：天体之间相互吸引、相互绕转，构成天体系统。

4.天体层次：由低到高依次为地月系、太阳系、银河系（河外星系）和可观测宇宙。

5.太阳系：太阳系由太阳（恒星）、行星及其卫星、小行星、彗星、流星体和行星际物质等组成。

其中太阳是太阳系的中心天体，质量占太阳系总质量的 99.86%。

6.八大行星按照距离太阳的远近：依次为水星、金星、地球、火星（小行星带）、木星（最大）、土星、天王星、海王星。

7.地球的普通性和特殊性普通性：地球在太阳系中的位置、体积、质量等方面与其他行星有相似之处。

特殊性：地球上存在生命，其条件包括适宜的温度和液态水（原因：日地距离适中）、适合生物呼吸的大气（原因：地球体积和质量适中）等。

8.太空探索的意义：有助于推动科技进步，促进新资源开发；帮助我们了解宇宙的起源与演化，探索生命的起源；通过太空探索，人类能更好地保护地球家园；体现了人类的探索精神和对未知世界的好奇心。

第二节地球与地球仪知识点2：地球的形状和大小1.形状：地球是一个两极稍扁、赤道略鼓的不规则球体。

2.大小：平均半径约为 6371 千米（赤道半径6378千米，极半径6357千米），赤道周长约为 4 万千米，表面积约为 5.1 亿平方千米。

3.地球仪：人们仿照地球的形状，并按照一定的比例把它缩小制作的地球模型。

4.地轴：地球仪上，地球绕转的轴，其北端始终指向北极星附近。

5.两极：地轴与地球表面相交的两点，叫两极。

对着北极星方向的点叫北极，它是地球上的最北点；与北极对应的点叫南极，是地球上的最南点。

2022-2023学年浙教版数学八上期中复习专题3 证明一、单选题（每题3分，共30分）1．（）用反证法证明命题：“如图，如果AB//CD，AB//EF，那么CD//EF.”证明的第一个步骤是（）A．假定CD//EF B．假定CD不平行于EFC．已知AB//EF D．假定AB不平行于EF【答案】B【知识点】反证法【解析】【解答】解：∵结论是CD∥EF，∴当用反证法证明这一命题时，第一步应该是：“假设CD和EF不平行”.故答案为：B.【分析】用反证法证明命题的第一步：通常是假设所证结论不成立，结合结论是“CD∥EF”，即可解答.2．（2022·槐荫模拟）下列各图中，已知∥1=∥2，不能证明AB∥CD的是（）A．B．C．D．【答案】B【知识点】平行线的判定【解析】【解答】：A、∵∥1=∥2，∴AB∥CD，该选项不符合题意；B、由∥1=∥2，不能判断AB∥CD，该选项符合题意；C、∵∥1=∥2，∥3=∥2，∴∥1=∥3，∴AB∥CD，该选项不符合题意；D、∵∥1=∥2，∴AB∥CD，该选项不符合题意；故答案为：B．【分析】根据平行线的判定方法逐项判断即可。

3．（2022·武安模拟）定理：三角形的内角和等于180°．已知：△ABC的三个内角为∠A，∠B，∠C．求证：∠A+∠B+∠C=180°．如图1，延长BC到点D，则∠ACD=∠A+∠B（三角形的一个外角等于和它不相邻的两个内角的和）．∵∠ACD+∠ACB=180°（平角的定义），∴∠A+∠B+∠ACB=180°（等量代换）．如图2，过点C作DE∥AB，∵DE∥AB，∠1=∠B（两直线平行，内错角相等），∠2=∠A（两直线平行，内错角相等），又∵∠1+∠ACB+∠2=180°（平角定义），∴∠A+∠ACB+∠B=180°（等量代换）．下列说法正确的是（）A．证法1采用了从特殊到一般的方法证明了该定理B．证法1用合理的推理证明了该定理C．证法2还需证明其他形状的三角形，该定理的证明过程才完整D．证法2用严谨的推理证明了该定理【答案】D【知识点】推理与论证【解析】【解答】解：三角形外角和性质是建立在三角形内角和定理的基础上的，不能循环证明，故A、B都不符合题意；证法2用严谨的推理证明了该定理，故不需要分三角形的形状，故C不符合题意；D符合题意，故答案为：D．【分析】利用理论与实践结合和根据三角形的平行的性质与平角的定义可以判断作答。
