In this step, give students a few minutes to read the passage . While they are reading, I will write some key words of the text on the blackboard. Then ask students to retell the passage according to the key words.By retelling, students can improve their ability of language organization and have an overall understanding of the article.Step 4 Group discussionIn this step, students will be divided into groups of 4 to discussion the following question: What qualities make a great person?After their discussion, invite a few groups to make a report to the class.This group discussion can practice students’ oral English and cultivate their abilities of cooperation and communication.Step 5. HomeworkLet students write a short passage to introduce a great person he or she admires.The homework can consolidate the knowledge the students have learned and cultivate their writing ability. Part 6 Blackboard Design(板书设计)That’s all my teaching procedures. Finally, I’d like to say sth about part 6 blackboard design. On the top is the title. On the left, there will be some new words and expressions. In the middle of the blackboard, I will write some useful sentence structures so that the students can know clearly what they’ve learned and then try to master the knowledge.OK. That’s all for my presentation. Thank you for your attention.

Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting. It would be revise and edit several times later. Writing, as a skill

Good afternoon, teachers, It’s my great pleasure to be here sharing my lesson with you.The content of my lesson is Senior English Book 3 Unit 5 Canada —— “The true North”.I’ll be ready to begin this lesson from five parts. Analysis of the teaching material,the teaching methods,the studying methods, the teaching procedure,and Blackboard design.First, let me talk about the teaching material.Part 1 Teaching Material:This unit is about the introduction of Canada. By studying of this unit,we’ll enable the students to learn the geography, population, main cities, and natural beauty, natural resources of Canada. Through the training of the unit, it also requires students to learn some Language skills such as the expressions of position and emotions.So it plays an important part in the English teaching in this book.After studying the teaching material and analyzing the rule of children’s growing of mind,I think the teaching aims are the followings:1.Knowledge objects:(1) make the students learn some new words and phrases(2) make the students understand the content of the lesson.2.Ability objects:(1)To develop the Ss’ abilities of listening, speaking, reading and writing. Especially reading and speaking ability.(2) learn to talk about the characters of Canada in English(3)To train the Ss’ ability of working in pairs.3.Emotion objects:(1)Enable students to understand the characters of Canada..(2)Stimulate Ss to work hard to make China stronger.Part 2 Teaching Methods:I think helping students learn to master new words and phrases and improve the students’ reading and speaking ability is import and the difficult.According to the analysis of the teaching material and the import points and the difficult points,I will use the following teaching methods : question-guiding approach; fast-reading and careful reading; multi-media teaching methods; discussion

Good morning, distinguished judges:It’s my honor to talk about my teaching ideas with you. Today my topic is Women of Achievement. My presentation consists of six parts: the analysis of teaching material and student, teaching aims, key and difficult points, teaching and studying method, teaching procedures and blackboard design.First, let’s focus on the analysis of teaching material. This lesson is from New Senior English for China Student’s Book 4 Unit 1, the reading part. The main topic of the passage is the introduction of a student of Africanwildlife. After this lesson, the students will learn more information about her studying chimps in Africa, and their reading and speaking abilities can be developed as well.The next part is the analysis of students. My students are in senior high students. They have learnt English for many years, they’ve known many words and sentences, but their speaking and reading abilities are still not very good. So I will practice their speaking and reading abilities through different exercises.According to the New Standard Curriculum and the present situation, I set the teaching aims as follows: firstly, knowledge aims. Students can grasp some new words, such as worthwhile, move off. Moreover, students can understand the content of the passage and get familiar with the topic of studying chimps in wildlife. Secondly, ability aims. Students can use reading strategies such as skimming and scanning in reading process. Thirdly, emotional aims. Students can have the awareness of protecting animals and care about animals.Based on the above analysis, the key point of this lesson is to get the main idea and the detailed information from the passage; the difficult point is to talk about the wildlife protection and use reading strategies.

Teaching plan for Unit 1 book3Good morning, teachers. It’s my great pleasure to be here because I can share my lesson with you and I can learn a lot from it.

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.

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.

(3)ATP的利用关于ATP的利用,一是要讲清楚吸能反应和放能反应与ATP的分解和合成的关系,二是要充分利用教材上的图解,让学生在看懂图解的基础上,讨论ATP还有哪些用途,从而对该图解进行补充和完善。3、课堂小结,强化认识。ATP作为能量的“通货”,在生物体生命活动中具有重要的意义。我们不仅要知道ATP的分子结构,还要掌握ATP是如何行使他的货币能力。4、板书设计结束:本节课设置了一系列问题情境,层层设问,在学生答问、质疑、讨论过程中让学生建构新概念和新的知识体系,并通过教师及时掌握反馈信息,适时点拨、调节,让学生在推理判断中培养良好的思维习惯和对知识的迁移能力,而且通过留出一定的时间让学生提问,体现了以学生为主体的思想。我的说课完毕,谢谢大家。

3、总结(这部分要5分钟)学生在教师的提示和问题的引导下,完成对本节课的知识的归纳和小结。利用简炼、清晰的语言,再一次的突出本节课的重点,起到画龙点睛的作用,培养了学生的表达能力。4、巩固练习(这部分要10分钟)用大屏幕投影把题目投影在屏幕上,让学生思考,然后回答。这部分安排10分钟的时间,让学生思考完成具有针对性的练习,进行知识巩固和教学效果反馈,及时纠正错误的理解和片面的认识。5、板书设计在板书中,我根据板书的“规范、工整和美观”的要求,结合所学的内容,设计了如图所示的板书。在其中,注重了重、难点的突出,使学生对知识的结构、层次、重点、难点一目了然,便于记忆和理解。四、效果分析对于反射的判断,学生仍有可能出现错误,如刺激坐骨神经肌肉的收缩,教师应强调没有完整的反射弧结构参与的不是反射。

苏格拉底把装有毒酒的杯子举到胸口,平静地说:“分手的时候到了,我将死,你们活下来,是谁的选择好,只有天知道。”说毕,一口喝干了毒酒。(2) 苏格拉底临死前对一个叫克力同的人说了这样一番话。克力同,我告诉你,这几天一直有一个神的声音在我心中晓喻我,他说:“苏格拉底,还是听我们的建议吧,我们是你的卫士。不要考虑你的子女、生命或其他东西胜过考虑什么是公正。……事实上你就要离开这里了。当你去死的时候,你是个牺牲品,但不是我们所犯错误的牺牲品,而是你同胞所犯错误的牺牲品。但你若用这种可耻的方法逃避,以错还错,以恶报恶,践踏你自己和我们订立的协议合约,那么你伤害了你最不应该伤害的,包括你自己、你的朋友、你的国家,还有我们。到那时,你活着面对我们的愤怒,你死后我们的兄弟、冥府里的法律也不会热情欢迎你;因为它们知道你试图尽力摧毁我们。别接受克力同的建议,听我们的劝告吧。”

一、说教材(一)教材分析本课所介绍的新文化运动,是继上一节所学的《西学东渐和维新变法思想》之后中国另一波影响巨大的思想解放潮流,旨在向西方学习、寻求强国御侮之道。在整个知识体系中,它既是资产阶级领导的旧民主主义革命的补课,又是无产阶级领导的新民主主义革命的序曲。它所带来的思想的空前解放,也就为马克思主义的传播创造了条件,为中共的成立奠定基础。这一课的学习能让学生清晰认识新文化运动和马克思主义在近代中国思想解放历程中的重要作用和巨大影响。与必修一和必修二政治经济史的结合也能让使学生强化历史联系。新课程标准对本课就做了明确的规定:1、概述新文化运动的主要内容,探讨其对近代中国思想解放的影响。2、简述马克思主义在中国传播的史实,认识马克思主义对中国历史发展的重大意义。根据课标要求,我制定了以下具体的三维目标。
