中考综合题?已知直径或作直径,要预见到两件事可以发生:直径上有个隐藏的中点(圆心);利用直径所对圆周角为直角构造直角三角形。涉及半径的基本套路。作半径:连半径,早等腰;作过切点的半径,半径垂直切线。涉及弦的基本套路。那么,中考综合题?一起来了解一下吧。
中考里面一道综合题一般会包含两到三个知识点,一般在中考一道大题里面的话就是有两到三个小题这样子,然后在第一、第二个小题都是比较好得分的,都是以基础问答这样子的一个形式去进行,并且就是包含了两个知识点。
就是第一题会问你这个东西具体是什么,第二个问题就会问你这个东西所属的领域是什么,然后第三个问题,也就是第三个知识点的话,它具体就会让你一些计算的过程或以一些思考的过程给你进行提问。
所以在中考一道综合题里面的话,一般就是包含两到三个知识点的。并且在中考综合题里面的话,如果是做得多一般都能够很快的得出答案,在前两道题里面是这样子,第三道题的话可能就需要一点时间。

Let me tell you a story .
A good friend of ___1___ lives with six hundred animals on an island . Ever ___2___ he left school , he has travelled all over the world ___3___ for animals for his own zoo . He writes books about his travels , and about his wonderful ___4___ . The money for his books helps him to pay for all the animal food . My friend told me that when he was looking for water last week (There is not enough water on the island , though there is a lot all around it ) , he ___5___ oil (石油) . He ___6___ money for his travels and for his zoo , and a little oil would buy ___7___ water for a long time , but he knows that if he tells anybody else about it , it will be the ___8___ of his zoo and his life’s work .
So I think he will not tell anybody ___9___ you and me about what he found — because oil and water can’t ___10___ together . Oil may bring greater trouble to his animals than not having enough water . Do you think so ?
二. 阅读下面的短文,根据每个空格中所给的词首字母填入适当的词,使短文意思完整。
数学课上,张老师出示了问题:如图1,AC,BD是四边形ABCD的对角线,若ACB=ACD=ABD=ADB=60,则线段BC,CD,AC三者之间有何等量关系?
经过思考,小明展示了一种正确的思路:如图2,延长CB到E,使BE=CD,连接AE,证得ABEADC,从而容易证明ACE是等边三角形,故AC=CE,所以AC=BC+CD.
小亮展示了另一种正确的思路:如图3,将ABC绕着点A逆时针旋转60,使AB与AD重合,从而容易证明ACF是等边三角形,故AC=CF,所以AC=BC+CD.
在此基础上,同学们作了进一步的研究:
(1)小颖提出:如图4,如果把“ACB=ACD=ABD=ADB=60”改为“ACB=ACD=ABD=ADB=45”,其它条件不变,那么线段BC,CD,AC三者之间有何等量关系?针对小颖提出的问题,请你写出结论,并给出证明.
(2)小华提出:如图5,如果把“ACB=ACD=ABD=ADB=60”改为“ACB=ACD=ABD=ADB=”,其它条件不变,那么线段BC,CD,AC三者之间有何等量关系?针对小华提出的问题,请你写出结论,不用证明.
题干分析:
(1)先判断出ADE=ABC,即可得出ACE是等腰三角形,再得出AEC=45,即可得出等腰直角三角形,即可;(判断ADE=ABC也可以先判断出点A,B,C,D四点共圆)
(2)先判断出ADE=ABC,即可得出ACE是等腰三角形,再用三角函数即可得出结论.
解题反思:
此题是几何变换综合题,主要考查了全等三角形的判定,四边形的内角和,等腰三角形的判定和性质,解本题的关键是构造全等三角形,是一道基础题目.
近年来,文综历史中考中的材料分析题成为了必考题目,让不少学生感到困扰。但实际上,只要我们掌握了基本的历史知识,并运用正确的解题方法,这道题目并没有想象中那么困难。接下来,我将分享一些实用的解题方法。
