For each one-degree change, your family can save the costs as well as energy!

平行线的判定（基础）知识讲解 【学习目标】 1.熟练掌握平行线的画法； 2.掌握平行公理及其推论； 3.掌握平行线的判定方法，并能运用“平行线的判定方法”，判定两条直线是否平行. 【要点梳理】 要点一、平行线的画法及平行公理 1.平行线的画法 用直尺和三角板作平行线的步骤： ①落：用三角板的一条斜边与已知直线重合. ②靠：用直尺紧靠三角板一条直角边. ③推：沿着直尺平移三角板,使与已知直线重合的斜边通过已知点. ④画：沿着这条斜边画一条直线,所画直线与已知直线平行. 2.平行公理及推论 平行公理：经过直线外一点，有且只有一条直线与这条直线平行． 推论：如果两条直线都与第三条直线平行，那么这两条直线也互相平行． 要点诠释： (1)平行公理特别强调“经过直线外一点”，而非直线上的点，要区别于垂线的第一性质． (2)公理中“有”说明存在；“只有”说明唯一． （3）“平行公理的推论”也叫平行线的传递性. 要点二、平行线的判定 判定方法1：同位角相等，两直线平行.如上图，几何语言： ∵∠3＝∠2 ∴AB∥CD（同位角相等，两直线平行） 判定方法2：内错角相等，两直线平行.如上图，几何语言： ∵∠1＝∠2 ∴AB∥CD（内错角相等，两直线平行） 判定方法3：同旁内角互补，两直线平行.如上图，几何语言： ∵∠4＋∠2＝180° ∴AB∥CD（同旁内角互补，两直线平行）
要点诠释：平行线的判定是由角相等或互补，得出平行，即由数推形. 【典型例题】 类型一、平行公理及推论 1．下列说法中正确的有 ( ) ①一条直线的平行线只有一条；②过一点与已知直线平行的直线只有一条；③因为a ∥b ，c ∥d ，所以a ∥d ；④经过直线外一点有且只有一条直线与已知直线平行． A ．1个 B 2个 C ．3个 D ．4个 【答案】 A 【解析】一条直线的平行线有无数条，故①错；②中的点在直线外还是在直线上位置不明确，所以②错，③中b 与c 的位置关系不明确，所以③也是错误的；根据平行公理可知④正确，故选A ． 【总结升华】本题主要考察的是“平行公理及推论”的内容，要正确理解必须要抓住关键字词及其重要特征，在理解的基础上记忆，在比较中理解． 举一反三： 【变式】直线a ∥b ，b ∥c ，则直线a 与c 的位置关系是 . 【答案】平行 类型二、平行线的判定 2.(江苏)如图所示，直线a 、b 被直线c 所截，现给出下列四个条件： ①∠1＝∠5； ②∠1＝∠7； ③∠2＋∠3＝180°； ④∠4＝∠7，其中能判断a ∥b 的条件的序号是 ( ). A ．①② B ．①③ C ．①④ D ．③④ 【思路点拨】根据平行线的判定方法进行判断． 【答案】A 【解析】①由∠1＝∠5可推出a ∥b ，理由是同位角相等，两直线平行． ②∵ ∠1＝∠7，又∠7＝∠5， ∴ ∠1＝∠5，可推出a ∥b ． ③∠2＋∠3＝180°不能推出a ∥b ． ④∠4＝∠7不能推出a ∥b ． 【总结升华】从题目的结论出发分析所要说明的结论能成立，必须具备的是哪些条件，再看这些条件成立又需具备什么条件，直到追溯到已知条件为止． 举一反三： 【变式1】如图，下列条件中，不能判断直线12l l ∥的是（ ）. A ．∠1＝∠3 B ．∠2＝∠3 C ．∠4＝∠5 D ．∠2＋∠4＝1800

北京四中 英语语法知识难点（三） （十）情态动词与助动词 I．要点 助动词本身无意义，在句中帮助主要动词构成一定的时态，语态、语气，或是帮助构成否定句和疑问句，常用的助动词有be, do, have, shall(should), will(would). 情态动词表一定的词义，本身并不表示动作或状态，而仅仅表达说话人的态度，它在句中须和主要动词一起构成谓语，主要的情态动词有can(could), may (might), must, have to, ought to, need, dare, shall, should, will, would. 1、can 能，可以，表说话人同意，许可还可表客观条件许可，如:You can go now. 提建议或请求时可用can I, can you表客气，如Can I buy you a drink? can和be able to表能力时的区别。 can表一般具有的能力，be able to表在特定条件下的能力，如:Although the driver was badly hurt, he was able to explain what had happened. 2、may （1）、可以，表说话人同意，许可或请求对方许可。You may go. （2）、（现在和将来）可能，也许，只用于肯定句和否定句中，如He may not be right. 3、must, have to must表主观上的必须，have to表客观上的必须，如:It's getting late. I have to go. -Must I go now. -Yes, you must. (No, you needn't./ No, you don't have to.) 4、need, dare这二词有实意动词和情态动词两种词性，如用作实意动词后接动词不定式to do，如用作情态动词后接动词原形。Need I go now? --Yes, you must./No, you needn't.) 5、shall用于第一人称疑问句中表说话人征求对方的意见或向对方请求，如，Shall we begin our lesson? 用于二、三人称陈述句，表说话人命令、警告、允诺、威胁等口吻，如: You shall fail if you don't work harder. 6、should表应该，意为有责任，有义务。如:We should try our best to make our country more beautiful. 7、will表有做某事的意志、意愿、安心、打算，如 "Will you lend me your book?" "Yes, I will."， 8、should have done表应该做而未做 must have done表对过去事实的肯定推测
Unit 2 What time do you go to school句式精讲+句式精练 句式精讲 1. What time do you usually get up? 1）这是一个用来询问什么时间做某事的常用句型，意思是“你几点起床？”。它的句式是“What＋time＋助动词do/does＋主语＋谓语动词原形＋其他？”。当主语是三单时用does，其余人称用do。它经常用来询问具体的点钟，相当于对划线部分（表示具体时间的状语）提问。 例如： I usually have lunch at 12:00. （对划线部分提问） 我通常在12点吃午饭。 What time do you usually have lunch? 你通常什么时间吃午饭？ －What time d oes Rick eat breakfast? 里克什么时候吃早餐？ －He eats breakfast at seven o’clock. 他七点吃早餐。 2）短语what time的意思是“几点”，它和when是同义词，都是对时间进行提问，但what time所问的时间范围比较小，一般用来提问比较精确的时间，回答的时候一般具体到几点。而when所问的时间范围比what time要大，回答的时候可以用几点钟，也可以是上午或者下午，甚至是哪一天、哪一年。 例如： －What time/When do you usually get up? 你通常什么时间起床？ －I usually get up at seven o’clock. 我通常七点起床。 －When is your birthday? 你的生日是什么时候？ －It’s May 10. 是5月10日。 3）询问时间还可以用句型： What’s the time now? = What time is it by your watch? ＝What’s the time by your watch?（你的表）现在几点了？ 回答别人询问几点可以用句型：“It＋is＋时间.”。 例如：It’s six. 现在六点了。 2. I usually get up at six thirty. 这个句型主要用来回答“What time /When…”句型的提问。在回答做某事的具体时间时，要注意英语时间的表达法。英语时间的表达法主要有以下几种情况： 1）如果时间在整点可以用“整点数字＋o’clock”这种形式表达，有时候可以不用o’clock。 例如：It’s eight (o’clock) now. 现在八点了。 2）如果是几点几分，分钟不超过半个小时（包括半小时），可以直接用数字表示。 例如：6:11→six eleven （6点11分） 也可以用介词past表示，past的前面是分钟，past的后面是钟点数，表示几点过了几分的意思。 例如；6:11→eleven past six （六点11分） 如果是15分钟可以用a quarter。 例如：7:15 →a quarter past seven （七点一刻） 如果是30分钟可以用half。 例如：6:30 →half past six （六点半）
第一名：五中 第二名：二中 优势就是生源很好，但也有少许人考不上大学，可能是老师疏于管理导致吧。第三名：景山中学 景山中学的生源也很好，但是可能因为孩子的家庭环境优越，所以造就了学校的攀比风强。 第四名：171中学 171中学的硬件设施一流，生源好，学生和老师的人品都很正派。同时171 中学非常重视尖子生，每年还组织他们出国见见世面，高考成绩非常好。 第五名：东直门中学 东中的硬件设施很好，实验班在东城数一数二。也就是因为这样使得孩子们的学业负担稍重。 第六名：166中学 166硬件设施不错，老师管理非常严格，校风不错。 第七名：22中 22中近几年的进步非常快，升学率都有所提高，这跟老师认真负责的工作态度是分不开的，而且22的地段很好。 东城区小升初择校推荐 东城区小升初择校推荐！（补充景山小五班） 在我十几年前跟东城上学的时候，2、5这些学校还是能和海淀西城的顶级名校分庭抗礼的。大部分东城的孩子为了上学近，基本都是将2、5作为首选。但近几年由于人大附中的异军突起带动了海淀整体进步极大，和西城四中恢复初中，等等这些因素加起来，现在东城初中的形势已经一落千丈了。 虽然高中还保留了大部分实力。
现在东城最好的，除5中外，就是象2中、东直门、171这样的学校也就是相当于海淀交大附、西城35这样的水平。 东城的另外一个特点就是和丰台出现12中、朝阳出现陈分那样，出现了 5中这样的绝对优势校。 北京五中分校中考总平均分达到525分。东城区总成绩在551分以上考生共45人，该校29人，占全区的64.44%；全区546分以上的109名高分生中，56人来自该校，占全区的一半以上。五中分校刘贝妮以562分的总成绩获得东城中考第一名，贺思宇(总分560分)、安琪儿(总分559分)分获东城区的第二名、第三名。(去年和前年东城区的中考状元也出自该校)。截至去年，五中分校已连续七年获得东城区中考总成绩的第一名，优秀率始终保持 在85%以上。 尤其是5中的两个数学实验班，绝对是东城的最高水平。08年5中仅给在学而思拿到迎春杯1、2等奖的孩子打了电话，虽然有很多学生没有去， 但也变相说明了其选拔的严格程度。 而5中这两个班基本是从获奖选手中挑，另外一大来源就是北京市数学学校---即市奥校（不是区奥校）。需要注意的是，这个学校最好的班是两个竞赛班（也叫超常班，很多名字），而不是1班。 东城区初中学校排名：

重点中学初中校直升本部高中的比例分析 点击查看原帖：2011年小升初建议 今年小升初点招已经逐步开始，家长都盯上了最知名中学的初中部或分校。其实，最知名的部分中学即便在小升初进去了，但中考的淘汰率是惊人的高的，感觉有些得不偿失。感觉小升初的家长应该特别了解这些名校中考时对本校小升初学生的保留率是很重要的，避免走弯路。 根据北京市教委的数据完成了对北京东城的2中、5中、景山、汇文中学、171中、东直门中学、55中、166中，西城的4中、实验中学、师大二附中、8中、师大一附中、161中学、15中、35中、13中、13分、铁二中、西城外国语，海淀的RDF中、北大附中、十一学校、101中学、清华附中、理工附中、八一中学、交大附中、中关村中学、20中学的小升初学生中考时的保留率的计算，感觉有些情况是让人出乎预料的。 举个例子，选择北京四中初中部的家长请注意，2010年北京四中的中考情况是： 1.中考本区统招：125/400=31.25%； 2.本区特长生、优秀生招收：42/400=10.5%； 3.两项合计：31.25%+10.5%=41.75%； 4.在外区招生：237/400=59.25%。 简单分析一下：北京四中统招400人，在西城区的招生比例仅为41.75%，13分每年考入北京四中的都在50多人，占四中录取率为13%以上，我们仅假定西城区其它全部的初中考入四中的人数仅占四中统招总人数的5%的话，那么四中初中部的学生能够在中考统招进入四中高中部的学生仅占41.75%—13%—5%=28.75%。（金老师已做回复，这是由于前几年四中初中部招生人数少所致，并不代表四中的初中水平差。经我重新计算，北京4中的实际淘汰率应为57%左右，在原西城4大名校中还是最高的。）做完这些统计后我感觉13分、5分、十一学校的实验班是北京是最值得上的，十一学校是初中直升本校高中人数及其实验班人数最多的学校。 2010年中考进入西城区市区重点中学的总人数是658人；进入东城区的总人数是65人；进入海淀区的总人数是665人。 西城区的铁二中是外区中端学生进入西城的最好跳板，铁二中中考在外区招收的学生比例是：50.53%，是北京市区级示范学校对外区招生人数最多的，说明了3个问题： 1
2019-2020学年北京四中七年级（上）期中数学试卷 一、选择题（每小题3分，共30分） 1. ?2的倒数是（） A.?2 B.?1 2C.1 2 D.2 【答案】 B 【考点】 倒数 【解析】 根据倒数的意义，乘积是1的两个数叫做互为倒数，据此解答． 【解答】 解：∵?2×(?1 2 )=1． ∴?2的倒数是?1 2 ， 故选B． 2. 举世瞩目的港珠澳大桥于2018年10月24日正式开通营运，它是迄今为止世界上最长的跨海大桥，全长约55000米．55000这个数用科学记数法可表示为（） A.5.5×103 B.55×103 C.0.55×105 D.5.5×104 【答案】 D 【考点】 科学记数法--表示较大的数 【解析】 科学记数法的表示形式为a×10n的形式，其中1≤|a|<10，n为整数．确定n的值时，要看把原数变成a时，小数点移动了多少位，n的绝对值与小数点移动的位数相同．当 原数绝对值大于10时，n是正数；当原数的绝对值小于1时，n是负数． 【解答】 55000这个数用科学记数法可表示为5.5×104， 3. 下列运算正确的是（） A.5a2?3a2＝2 B.2x2+3x2＝5x4 C.3a+2b＝5ab D.7ab?6ba＝ab 【答案】 D 【考点】 合并同类项 【解析】 根据合并同类项系数相加字母及指数不变，可得答案． 【解答】 A、5a2?3a2＝2a的平方，故A错误；
B、2x2+3x2＝5x2，故B错误； C、不是同类项不能合并，故C错误； D、合并同类项系数相加字母及指数不变，故D正确； 4. 有理数a，b在数轴上的对应位置如图，则下列结论正确的是（） <0 C.a+b<0 D.a?b<0 A.ab>0 B.a b 【答案】 B 【考点】 数轴 【解析】 根据所给的图形判断出a>0，b<0，|a|>|b|，再对每一选项进行分析，即可得出答案． 【解答】 根据图形可知：a>0，b<0，|a|>|b|， <0，a+b>0，a?b>0， 则ab<0，a b 下列结论正确的是B； 5. 用代数式表示“m的2倍与n平方的差”，正确的是（） A.(2m?n)2 B.2(m?n)2 C.2m?n2 D.(m?2n)2 【答案】 C 【考点】 列代数式 【解析】 根据题意可以用代数式表示m的2倍与n平方的差． 【解答】 用代数式表示“m的2倍与n平方的差”是：2m?n2， 6. 下列说法正确的是（） A.平方等于本身的数是0和1 B.?a一定是负数 C.一个有理数不是正数就是负数 D.一个数的绝对值一定是正数 【答案】 A 【考点】 有理数的乘方 正数和负数的识别 有理数的概念及分类
