北师大初中七年级数学下册三角形的三边关系教案
方法总结：绝对值的化简首先要判断绝对值符号里面的式子的正负，然后根据绝对值的性质将绝对值的符号去掉，最后进行化简．此类问题就是根据三角形的三边关系，判断绝对值符号里面式子的正负，然后进行化简．三、板书设计1．三角形按边分类：有两边相等的三角形叫做等腰三角形，三边都相等的三角形是等边三角形，三边互不相等的三角形是不等边三角形．2．三角形中三边之间的关系：三角形任意两边之和大于第三边，三角形任意两边之差小于第三边．本节课让学生经历一个探究解决问题的过程，抓住“任意的三条线段能不能围成一个三角形”引发学生探究的欲望，围绕这个问题让学生自己动手操作，发现有的能围成，有的不能围成，由学生自己找出原因，为什么能？为什么不能？初步感知三条边之间的关系，重点研究“能围成三角形的三条边之间到底有什么关系”．通过观察、验证、再操作，最终发现三角形任意两边之和大于第三边这一结论．这样教学符合学生的认知特点，既增加了学习兴趣，又增强了学生的动手能力
北师大初中九年级数学下册圆周角和圆心角的关系教案
解析：点E是BC︵的中点，根据圆周角定理的推论可得∠BAE＝∠CBE，可证得△BDE∽△ABE，然后由相似三角形的对应边成比例得结论．证明：∵点E是BC︵的中点，即BE︵＝CE︵，∴∠BAE＝∠CBE.∵∠E＝∠E(公共角)，∴△BDE∽△ABE，∴BE∶AE＝DE∶BE，∴BE2＝AE·DE.方法总结：圆周角定理的推论是和角有关系的定理，所以在圆中，解决相似三角形的问题常常考虑此定理．三、板书设计圆周角和圆心角的关系1．圆周角的概念2．圆周角定理3．圆周角定理的推论本节课的重点是圆周角与圆心角的关系，难点是应用所学知识灵活解题．在本节课的教学中，学生对圆周角的概念和“同弧所对的圆周角相等”这一性质较容易掌握，理解起来问题也不大，而对圆周角与圆心角的关系理解起来则相对困难，因此在教学过程中要着重引导学生对这一知识的探索与理解．还有些学生在应用知识解决问题的过程中往往会忽略同弧的问题，在教学过程中要对此予以足够的强调，借助多媒体加以突出.

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.

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.
