复习专题一般将来时-知识点归纳与练习 一、初中英语一般将来时 1．—Tom wants to know if you ________ a picnic next Sunday. —Yes. But if it ________， we'll visit the museum instead. A. will have; will rain B. have; rains C. have; will rain D. will have; rains 【答案】D 【解析】【分析】句意：汤姆想知道下周日你们是否去野炊。是的，但是如果下雨的话，我们将改去参观博物馆。if引导宾语从句时，意为“是否”，句子时态根据句意选用，if 作为“假如”时，引导的是条件状语从句，主句用一般将来时，从句用一般现在时表示将来，故选D 【点评】此考点也是中考最喜欢出现的考点，if除了可以引导条件状语从句外，还可以引导宾语从句，翻译成“是否”。引导宾语从句时没有“主将从现”的说法。除了if外，还有when, as soon as也一样要注意“主将从现”。 2．— Excuse me. Could you tell me ? — It will leave at 4:00 p.m. A. how will you go to Shanghai B. how you will go to Shanghai C. when the bus would leave for Shanghai D. when the bus will leave for Shanghai 【答案】 D 【解析】【分析】这是一道根据回答写出问句所缺成分的题目，阅题时要仔细分析回答的句子。 句意：打扰一下，你能告诉我这辆公交车什么时候动身前往上海吗？它将会在下午4点的时候离开。据回答知问句问的是时间，故排除A和B。由题知，句子是一般将来时，故问句中也要用一般将来时态。故选D。 【点评】本题需要考生根据回答反推问题，在阅题时要仔细审题。 3．Susan and her sister ________ some photos in the park the day after tomorrow. A. take B. took C. will take 【答案】 C 【解析】【分析】句意：Susan和她的妹妹后天会在公园照一些照片。根据时间状语the day after tomorrow，可知句子时态是一般将来时，一般将来时结构will+do，故选C。 【点评】此题考查一般将来时。根据时间状语确定句子时态。 4．In the near future, there ________ self-driving cars in our city. A. is B. was C. are D. will be
集合 一．【课标要求】 1．集合的含义与表示 （1）通过实例，了解集合的含义，体会元素与集合的“属于”关系； （2）能选择自然语言、图形语言、集合语言（列举法或描述法）描述不同的具体问题，感受集合语言的意义和作用； 2．集合间的基本关系 （1）理解集合之间包含与相等的含义，能识别给定集合的子集； （2）在具体情境中，了解全集与空集的含义； 3．集合的基本运算 （1）理解两个集合的并集与交集的含义，会求两个简单集合的并集与交集； （2）理解在给定集合中一个子集的补集的含义，会求给定子集的补集； （3）能使用Venn图表达集合的关系及运算，体会直观图示对理解抽象概念的作用二．【命题走向】 有关集合的高考试题，考查重点是集合与集合之间的关系，近年试题加强了对集合的计算化简的考查，并向无限集发展，考查抽象思维能力，在解决这些问题时，要注意利用几何的直观性，注意运用Venn图解题方法的训练，注意利用特殊值法解题，加强集合表示方法的转换和化简的训练。考试形式多以一道选择题为主。 预测高考将继续体现本章知识的工具作用，多以小题形式出现，也会渗透在解答题的表达之中，相对独立。具体 三．【要点精讲】 1．集合：某些指定的对象集在一起成为集合 a∈；若b不是集合A的元素，（1）集合中的对象称元素，若a是集合A的元素，记作A b?； 记作A （2）集合中的元素必须满足：确定性、互异性与无序性； 确定性：设A是一个给定的集合，x是某一个具体对象，则或者是A的元素，或 者不是A的元素，两种情况必有一种且只有一种成立；
互异性：一个给定集合中的元素，指属于这个集合的互不相同的个体（对象），因此，同一集合中不应重复出现同一元素； 无序性：集合中不同的元素之间没有地位差异，集合不同于元素的排列顺序无关； （3）表示一个集合可用列举法、描述法或图示法； 列举法：把集合中的元素一一列举出来，写在大括号内； 描述法：把集合中的元素的公共属性描述出来，写在大括号{}内。 具体方法：在大括号内先写上表示这个集合元素的一般符号及取值（或变化）范围，再画一条竖线，在竖线后写出这个集合中元素所具有的共同特征。 注意：列举法与描述法各有优点，应该根据具体问题确定采用哪种表示法，要注意，一般集合中元素较多或有无限个元素时，不宜采用列举法。 （4）常用数集及其记法： 非负整数集（或自然数集），记作N ； 正整数集，记作N *或N +； 整数集，记作Z ； 有理数集，记作Q ； 实数集，记作R 。 2．集合的包含关系： （1）集合A 的任何一个元素都是集合B 的元素，则称A 是B 的子集（或B 包含A ），记作A ?B （或B A ?）； 集合相等：构成两个集合的元素完全一样。若A ?B 且B ?A ，则称A 等于B ，记作A =B ；若A ?B 且A ≠B ，则称A 是B 的真子集，记作A B ； （2）简单性质：1）A ?A ；2）Φ?A ；3）若A ?B ，B ?C ，则A ?C ；4）若集合A 是n 个元素的集合，则集合A 有2n 个子集（其中2n －1个真子集）； 3．全集与补集： （1）包含了我们所要研究的各个集合的全部元素的集合称为全集，记作U ； （2）若S 是一个集合，A ?S ，则，S C =}|{A x S x x ?∈且称S 中子集A 的补集； （3）简单性质：1）S C (S C )=A ；2）S C S=Φ，ΦS C =S 4．交集与并集：
圆的知识点总结 （一）圆的有关性质 ［知识归纳］ 1. 圆的有关概念： 圆、圆心、半径、圆的内部、圆的外部、同心圆、等圆； 弦、直径、弦心距、弧、半圆、优弧、劣弧、等弧、弓形、弓形的高； 圆的内接三角形、三角形的外接圆、三角形的外心、圆内接多边形、多边形的外接圆；圆心角、圆周角、圆内接四边形的外角。 2. 圆的对称性 圆是轴对称图形，经过圆心的每一条直线都是它的对称轴，圆有无数条对称轴； 圆是以圆心为对称中心的中心对称图形； 圆具有旋转不变性。 3. 圆的确定 不在同一条直线上的三点确定一个圆。 4. 垂直于弦的直径 垂径定理垂直于弦的直径平分这条弦，并且平分弦所对的两条弧； 推论1 （1）平分弦（不是直径）的直径垂直于弦，并且平分弦所对的两条弧； （2）弦的垂直平分线经过圆心，并且平分弦所对的两条弧； （3）平分弦所对的一条弧的直径垂直平分弦，并且平分弦所对的另一条弧。 垂径定理及推论1 可理解为一个圆和一条直线具备下面五个条件中的任意两个，就 可推出另外三个：①过圆心；②垂直于弦；③平分弦（不是直径）； ④平分弦所对的优弧；⑤平分弦所对的劣弧。 1
推论2圆的两条平行弦所夹的弧相等。 5. 圆心角、弧、弦、弦心距之间的关系 定理在同圆或等圆中，相等的圆心角所对的弧相等，所对的弦相等；所对的弦的弦心距相等。 推论在同圆或等圆中，如果两个圆心角、两条弧、两条弦或两条弦的弦心距中有一组量相等，那么它们所对应的其余各组量都分别相等。 此定理和推论可以理解成：在同圆或等圆中，满足下面四个条件中的任何一个就能推出另外三个：①两个圆心角相等；②两个圆心角所对的弧相等；③两个圆 心角或两条弧所对的弦相等；④两条弦的弦心距相等。 圆心角的度数等于它所对的弧的度数。 6. 圆周角 定理一条弧所对的圆周角等于它所对的圆心角的一半； 推论1同弧或等弧所对的圆周角相等；在同圆或等圆中，相等的圆周角所对的弧也相等； 推论2半圆（或直径）所对的圆周角是直角；90°的圆周角所对的弦是直径； 推论3如果三角形一边上的中线等于这边的一半，那么这个三角形是直角三角形。 圆周角的度数等于它所对的弧的度数的一半。 7. 圆内接四边形的性质 圆内接四边形的对角互补，并且任何一个外角都等于它的内对角。 ※8. 轨迹 轨迹符合某一条件的所有的点组成的图形，叫做符合这个条件的点的轨迹。 （1）平面内，到一定点的距离等于定长的点的轨迹，是以这个定点为圆心，定长为半径的圆； （2）平面内，和已知线段两个端点的距离相等的点的轨迹，是这条线段的垂直平分线； （3）平面内，到已知角两边的距离相等的点的轨迹，是这个角的平分线。 ［例题分析］ 例1. 已知：如图1，在⊙O中，半径OM⊥弦AB于点N。 图1 ①若AB ＝，ON＝1，求MN的长； ②若半径OM＝R，∠AOB＝120°，求MN的长。 解：①∵AB ＝，半径OM⊥AB，∴AN＝BN ＝ ∵ON＝1，由勾股定理得OA＝2 ∴MN＝OM－ON＝OA－ON＝1 ②∵半径OM⊥AB，且∠AOB＝120°∴∠AOM＝60° 2
第一章集合 §1．1集合 基础知识点： ⒈集合的定义：一般地，我们把研究对象统称为元素，一些元素组成的总体叫集合， 也简称集。 2.表示方法：集合通常用大括号{ }或大写的拉丁字母A,B,C…表示， 而元素用小写的拉丁字母a,b,c…表示。 3.集合相等：构成两个集合的元素完全一样。 4.常用的数集及记法： 非负整数集（或自然数集），记作N； 正整数集，记作N*或N+；N内排除0的集. 整数集，记作Z；有理数集，记作Q；实数集，记作R； 5.关于集合的元素的特征 ⑴确定性：给定一个集合，那么任何一个元素在不在这个集合中就确定了。 如：“地球上的四大洋”（太平洋,大西洋，印度洋，北冰洋）。“中国古代四大 发明”（造纸，印刷，火药，指南针）可以构成集合，其元素具有确定性； 而“比较大的数”，“平面点P周围的点”一般不构成集合，因为组成它的元 素是不确定的. ⑵互异性：一个集合中的元素是互不相同的，即集合中的元素是不重复出现的。. 如:方程(x-2)(x-1)2=0的解集表示为{1, 2},而不是{1, 1, 2} ⑶无序性：即集合中的元素无顺序,可以任意排列、调换。 练1：判断以下元素的全体是否组成集合，并说明理由： ⑴大于3小于11的偶数；⑵我国的小河流； ⑶非负奇数；⑷方程x2+1=0的解； ⑸徐州艺校校2011级新生；⑹血压很高的人； ⑺著名的数学家；⑻平面直角坐标系内所有第三象限的点 6.元素与集合的关系：(元素与集合的关系有“属于∈”及“不属于?”两种) ⑴若a是集合A中的元素，则称a属于集合A，记作a∈A； ⑵若a不是集合A的元素，则称a不属于集合A，记作a?A。 例如，（1）A表示“1~20以内的所有质数”组成的集合，则有3∈A，4?A，等等。 （2）A={2，4，8，16}，则4∈A，8∈A，32?A.
