直线的两点式方程教学设计人教A版高中数学选择性必修第一册
解析：①过原点时，直线方程为y＝－34x.②直线不过原点时，可设其方程为xa＋ya＝1，∴4a＋－3a＝1，∴a＝1.∴直线方程为x＋y－1＝0.所以这样的直线有2条，选B.答案：B4.若点P(3,m)在过点A(2,-1),B(-3,4)的直线上,则m= . 解析:由两点式方程得,过A,B两点的直线方程为(y"-(-" 1")" )/(4"-(-" 1")" )=(x"-" 2)/("-" 3"-" 2),即x+y-1=0.又点P(3,m)在直线AB上,所以3+m-1=0,得m=-2.答案:-2 5.直线ax+by=1(ab≠0)与两坐标轴围成的三角形的面积是 . 解析:直线在两坐标轴上的截距分别为1/a 与 1/b,所以直线与坐标轴围成的三角形面积为1/(2"|" ab"|" ).答案:1/(2"|" ab"|" )6.已知三角形的三个顶点A(0,4)，B(－2,6)，C(－8,0)．(1)求三角形三边所在直线的方程；(2)求AC边上的垂直平分线的方程．解析(1)直线AB的方程为y－46－4＝x－0－2－0，整理得x＋y－4＝0；直线BC的方程为y－06－0＝x＋8－2＋8，整理得x－y＋8＝0；由截距式可知，直线AC的方程为x－8＋y4＝1，整理得x－2y＋8＝0.(2)线段AC的中点为D(－4,2)，直线AC的斜率为12，则AC边上的垂直平分线的斜率为－2，所以AC边的垂直平分线的方程为y－2＝－2(x＋4)，整理得2x＋y＋6＝0.
直线的一般式方程教学设计人教A版高中数学选择性必修第一册
解析:当a0时,直线ax-by=1在x轴上的截距1/a0,在y轴上的截距-1/a>0.只有B满足.故选B.答案:B 3．过点(1,0)且与直线x－2y－2＝0平行的直线方程是( ) A．x－2y－1＝0 B．x－2y＋1＝0C．2x＋y＝2＝0 D．x＋2y－1＝0答案A 解析：设所求直线方程为x－2y＋c＝0，把点(1,0)代入可求得c＝－1.所以所求直线方程为x－2y－1＝0.故选A.4．已知两条直线y＝ax－2和3x－(a＋2)y＋1＝0互相平行，则a＝________.答案：1或－3 解析：依题意得：a(a＋2)＝3×1，解得a＝1或a＝－3.5．若方程(m2－3m＋2)x＋(m－2)y－2m＋5＝0表示直线．(1)求实数m的范围；(2)若该直线的斜率k＝1，求实数m的值．解析： (1)由m2－3m＋2＝0，m－2＝0，解得m＝2，若方程表示直线，则m2－3m＋2与m－2不能同时为0，故m≠2.(2)由－?m2－3m＋2?m－2＝1，解得m＝0.

空间向量基本定理教学设计人教A版高中数学选择性必修第一册
反思感悟用基底表示空间向量的解题策略1.空间中,任一向量都可以用一个基底表示,且只要基底确定,则表示形式是唯一的.2.用基底表示空间向量时,一般要结合图形,运用向量加法、减法的平行四边形法则、三角形法则,以及数乘向量的运算法则,逐步向基向量过渡,直至全部用基向量表示.3.在空间几何体中选择基底时,通常选取公共起点最集中的向量或关系最明确的向量作为基底,例如,在正方体、长方体、平行六面体、四面体中,一般选用从同一顶点出发的三条棱所对应的向量作为基底.例2.在棱长为2的正方体ABCD-A1B1C1D1中,E,F分别是DD1,BD的中点,点G在棱CD上,且CG=1/3 CD(1)证明:EF⊥B1C;(2)求EF与C1G所成角的余弦值.思路分析选择一个空间基底,将(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)证明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?与(C_1 G) ?夹角的余弦值即可.(1)证明:设(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,则{i,j,k}构成空间的一个正交基底.

１.做学问之前首先学会做人2.知识文化修养和思想道德修养的关系三.追求更高的思想道德目标㈤ 说教学评价和反思：1.这节课主要是以学生为主体，老师为主导，让学生充分发表自己的看法，把理论的知识结合在实际的日常生活中，鼓励学生充分发表自己的意见，能调动学生学习的积极性，达到教学目的。这节课学生讨论，发言的机会很多，但由于我校的学生的基础薄弱，在发言时难免偏离老师引导的方向，甚至出现毫不相干的说法，由于本人经验不够此时如何去引导他们可能做的还不够好。2.新课程的教学，如何突破书本知识的局限，延伸更深层次的内容是一个难题。本节课在知识的处理上，把道德的重要性与道德的层次两个知识点补充了进去，目的是让学生在学习之前有一个情感的铺垫，从而更好地达到教学目标。

生2：每逢清明，或其他一些死者的纪念日，人们总要为死去的亲人烧纸钱。这幅漫画由烧纸钱演变为烧“家电”，说明随着社会环境的变化，人们根深蒂固的一些封建思想，还在影响着人们的生活。要花大力气去破除封建迷信活动。师：说到底，算命、烧纸钱是封建迷信活动，从文化角度来说，是落后文化。我们一起来看看在现实生活中，还有哪些落后文化在影响着人们的生活。生1：在一些边远落后地区，大人小孩生了病，不是看医生，而是让巫婆神汉来治，结果往往耽误了诊疗时间，有的甚至还丢掉了性命。生2：“重男轻女”“多子多福”，红白事大操大办现象在有些地方还很严重。师：这些落后文化都有哪些共同特征？在你看来，这些现象有哪些危害？生3：这些落后文化，在内容上带有迷信、愚昧、颓废、庸俗等色彩，在形式上常常以传统习俗的形式表现出来，如人们常见的看相、算命、测字、看风水等。它会麻痹人的意志，使人消极、悲观、绝望，对理想、前途、信念丧失信心；破坏社会的风气。

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

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.
