1.两圆x2+y2-1=0和x2+y2-4x+2y-4=0的位置关系是( )A.内切 B.相交 C.外切 D.外离解析:圆x2+y2-1=0表示以O1(0,0)点为圆心,以R1=1为半径的圆.圆x2+y2-4x+2y-4=0表示以O2(2,-1)点为圆心,以R2=3为半径的圆.∵|O1O2|=√5,∴R2-R1<|O1O2|<R2+R1,∴圆x2+y2-1=0和圆x2+y2-4x+2y-4=0相交.答案:B2.圆C1:x2+y2-12x-2y-13=0和圆C2:x2+y2+12x+16y-25=0的公共弦所在的直线方程是 . 解析:两圆的方程相减得公共弦所在的直线方程为4x+3y-2=0.答案:4x+3y-2=03.半径为6的圆与x轴相切,且与圆x2+(y-3)2=1内切,则此圆的方程为( )A.(x-4)2+(y-6)2=16 B.(x±4)2+(y-6)2=16C.(x-4)2+(y-6)2=36 D.(x±4)2+(y-6)2=36解析:设所求圆心坐标为(a,b),则|b|=6.由题意,得a2+(b-3)2=(6-1)2=25.若b=6,则a=±4;若b=-6,则a无解.故所求圆方程为(x±4)2+(y-6)2=36.答案:D4.若圆C1:x2+y2=4与圆C2:x2+y2-2ax+a2-1=0内切,则a等于 . 解析:圆C1的圆心C1(0,0),半径r1=2.圆C2可化为(x-a)2+y2=1,即圆心C2(a,0),半径r2=1,若两圆内切,需|C1C2|=√(a^2+0^2 )=2-1=1.解得a=±1. 答案:±1 5. 已知两个圆C1:x2+y2=4,C2:x2+y2-2x-4y+4=0,直线l:x+2y=0,求经过C1和C2的交点且和l相切的圆的方程.解:设所求圆的方程为x2+y2+4-2x-4y+λ(x2+y2-4)=0,即(1+λ)x2+(1+λ)y2-2x-4y+4(1-λ)=0.所以圆心为 1/(1+λ),2/(1+λ) ,半径为1/2 √((("-" 2)/(1+λ)) ^2+(("-" 4)/(1+λ)) ^2 "-" 16((1"-" λ)/(1+λ))),即|1/(1+λ)+4/(1+λ)|/√5=1/2 √((4+16"-" 16"(" 1"-" λ^2 ")" )/("(" 1+λ")" ^2 )).解得λ=±1,舍去λ=-1,圆x2+y2=4显然不符合题意,故所求圆的方程为x2+y2-x-2y=0.
倾斜角与斜率教学设计人教A版高中数学选择性必修第一册
(2)l的倾斜角为90°,即l平行于y轴,所以m+1=2m,得m=1.延伸探究1 本例条件不变,试求直线l的倾斜角为锐角时实数m的取值范围.解:由题意知(m"-" 1"-" 1)/(m+1"-" 2m)>0,解得1<m<2.延伸探究2 若将本例中的“N(2m,1)”改为“N(3m,2m)”,其他条件不变,结果如何?解:(1)由题意知(m"-" 1"-" 2m)/(m+1"-" 3m)=1,解得m=2.(2)由题意知m+1=3m,解得m=1/2.直线斜率的计算方法(1)判断两点的横坐标是否相等,若相等,则直线的斜率不存在.(2)若两点的横坐标不相等,则可以用斜率公式k=(y_2 "-" y_1)/(x_2 "-" x_1 )(其中x1≠x2)进行计算.金题典例 光线从点A(2,1)射到y轴上的点Q,经y轴反射后过点B(4,3),试求点Q的坐标及入射光线的斜率.解:(方法1)设Q(0,y),则由题意得kQA=-kQB.∵kQA=(1"-" y)/2,kQB=(3"-" y)/4,∴(1"-" y)/2=-(3"-" y)/4.解得y=5/3,即点Q的坐标为 0,5/3 ,∴k入=kQA=(1"-" y)/2=-1/3.(方法2)设Q(0,y),如图,点B(4,3)关于y轴的对称点为B'(-4,3), kAB'=(1"-" 3)/(2+4)=-1/3,由题意得,A、Q、B'三点共线.从而入射光线的斜率为kAQ=kAB'=-1/3.所以,有(1"-" y)/2=(1"-" 3)/(2+4),解得y=5/3,点Q的坐标为(0,5/3).
直线与圆的位置关系教学设计人教A版高中数学选择性必修第一册
切线方程的求法1.求过圆上一点P(x0,y0)的圆的切线方程:先求切点与圆心连线的斜率k,则由垂直关系,切线斜率为-1/k,由点斜式方程可求得切线方程.若k=0或斜率不存在,则由图形可直接得切线方程为y=b或x=a.2.求过圆外一点P(x0,y0)的圆的切线时,常用几何方法求解设切线方程为y-y0=k(x-x0),即kx-y-kx0+y0=0,由圆心到直线的距离等于半径,可求得k,进而切线方程即可求出.但要注意,此时的切线有两条,若求出的k值只有一个时,则另一条切线的斜率一定不存在,可通过数形结合求出.例3 求直线l:3x+y-6=0被圆C:x2+y2-2y-4=0截得的弦长.思路分析:解法一求出直线与圆的交点坐标,解法二利用弦长公式,解法三利用几何法作出直角三角形,三种解法都可求得弦长.解法一由{■(3x+y"-" 6=0"," @x^2+y^2 "-" 2y"-" 4=0"," )┤得交点A(1,3),B(2,0),故弦AB的长为|AB|=√("(" 2"-" 1")" ^2+"(" 0"-" 3")" ^2 )=√10.解法二由{■(3x+y"-" 6=0"," @x^2+y^2 "-" 2y"-" 4=0"," )┤消去y,得x2-3x+2=0.设两交点A,B的坐标分别为A(x1,y1),B(x2,y2),则由根与系数的关系,得x1+x2=3,x1·x2=2.∴|AB|=√("(" x_2 "-" x_1 ")" ^2+"(" y_2 "-" y_1 ")" ^2 )=√(10"[(" x_1+x_2 ")" ^2 "-" 4x_1 x_2 "]" ┴" " )=√(10×"(" 3^2 "-" 4×2")" )=√10,即弦AB的长为√10.解法三圆C:x2+y2-2y-4=0可化为x2+(y-1)2=5,其圆心坐标(0,1),半径r=√5,点(0,1)到直线l的距离为d=("|" 3×0+1"-" 6"|" )/√(3^2+1^2 )=√10/2,所以半弦长为("|" AB"|" )/2=√(r^2 "-" d^2 )=√("(" √5 ")" ^2 "-" (√10/2) ^2 )=√10/2,所以弦长|AB|=√10.
人教版高中历史必修1探究活动课“黑暗”的西欧中世纪—历史素材阅读与研讨教案
一、活动内容分析西欧从5世纪末至9世纪历经四个世纪完成了由奴隶制度向封建制度的转变，西欧中世纪即西欧的封建社会，形成了与中国封建社会不同的特点。理解这些特点，将有助于学生理解西欧在世界上最早进入资本主义社会的原因。尽管神学世界观笼罩了西方中世纪，是黑暗的，但是应看到，自古代流传下来的政治思想传统如平等、自由、民主、法制等思想史都以不同的形式保存下来。欧洲的中世纪表面上看起来是一个阴森森的一千年（五百年到一千五百年），但实际上确实孕育了西方近代文明的重要时期。从探究活动的内容上看与第二单元的古代希腊罗马的政治制度及第三单元近代西方资本主义政治制度的确立与发展明确相关，有承上启下的作用。二、活动重点设计理解西欧封建社会的政治特点及对后世的影响；正确认识基督教文明
端午节国旗下讲话稿：端午节文化
老师们，同学们：大家早上好!我今天国旗下讲话的题目是：端午节文化今天是6月9号，农历五月初一。到本周五，农历五月初五是我国的传统节日——端午节。端午节，又称端阳节。关于端午节起源的传说有很多，其中，纪念屈原的说法流传得最广。历史上的这天人们会通过赛龙舟、包粽子等形式来纪念一颗不朽的灵魂——屈原。屈原是我国古代伟大的爱国诗人，出生在两千多年前战国时期的楚国。他为人正直，学识渊博，很有才干，在楚国担任要职。因为他坚决主张抗击秦国侵略，而受到打击、排斥，被楚王赶出了朝廷。屈原悲愤至极，在流放途中写下了许多充满爱国主义精神的诗篇，如：《离骚》、《天问》、《九歌》等影响深远的诗篇。后来，秦国军队攻占了楚国的都城。楚国失地千里，尸横遍野。屈原心如刀绞，他不愿意看到国破家亡的惨景，就在农历五月五日这一天，在写下了绝笔《怀沙》之后，抱石投江而死，以自己的生命谱写了一曲壮丽的爱国主义乐章。

人教版高中地理必修1第二章第四节全球气候变化教案
气候变化对健康的影响 气候变化对人体健康的不良影响是不难发现的：热浪冲击频繁加重可致死亡率及某些疾病、特别是心脏呼吸系统疾病发病率增加；对气候变化敏感的传染性疾病如疟疾和登革热的传播范围可能增加。极端气候事件, 如干旱、水灾、暴风雨等, 使死亡率、伤残率及传染病疾病率上升, 并增加社会心理压力。某些媒介疾病的加重也可能与气候变化有间接的关系, 如疟疾是通过蚊子传播的疾病,气候变化可能使某些变暖地区的蚊子数目增加, 从而加重了疟疾的发生。我国1994年疟疾的发病率为5.3408/10万, 居全国法定传染病的第六位。血吸虫病的发展与高温及灌溉系统的扩增有关。我国1994年南方12省市血吸虫病患者的检出率高达3.67%，不能忽视气候变化对此的可能影响。还有一些疾病，如睡眠病、登革热、黑热病等也有与气候关系的报道。另外, CO2、一些空气污染物如氮氧化物、臭氧等可增加过敏疾患及心脏呼吸系统疾病和死亡。

4、维新思想推动下的变法运动虽然失败了。但这是中国近代真正意义上的一次思想解放潮流，为什么？展开：维新派提倡西学，兴民权，对封建专制制度和传统观念进行了冲击，促进了中国人民的觉醒，为资产阶级民主思想的传播奠定了基础，具有思想解放的启蒙作用。是一次救亡图存的爱国运动，也是一次发展资本主义的改革运动；他们提倡资产阶级新学，批判封建主义旧学，引导人们重新认识世界，他们痛感民族危机的严重，号召人们奋起救国，谋求国家的独立富强；给古老的中国社会注入的活力是不可低估的，站在历史长河的高度看，由传统农耕社会向近代工业社会转变是一股不可抗拒的历史潮流，尽管它在19世纪末的中国遭到了暂时挫折，但对清朝的封建专制统治却是一次巨大的强烈的冲击波，它留下的痕迹是永不磨灭的，是永远鼓舞与启迪后人的。

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate. Students not only learn the festival, but touch and feel the Inner Mongolian’s character, the spirit and cultural atmosphere, which can help students form the cultural awareness and learn to enjoy and value the diversity of Chinese culture.Concretely, the dairy tells the experience that the author spent the Naadam Festival in Inner Mongolia Autonomous Region with his/her friend. The structure is clear. In the opening paragraph, it introduces the topic of the Naadam Festival and the whole feeling. Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1.
