北师大初中九年级数学下册垂径定理教案
方法总结：垂径定理虽是圆的知识，但也不是孤立的，它常和三角形等知识综合来解决问题，我们一定要把知识融会贯通，在解决问题时才能得心应手．变式训练：见《学练优》本课时练习“课后巩固提升”第2题【类型三】 动点问题如图，⊙O的直径为10cm，弦AB＝8cm，P是弦AB上的一个动点，求OP的长度范围．解析：当点P处于弦AB的端点时，OP最长，此时OP为半径的长；当OP⊥AB时，OP最短，利用垂径定理及勾股定理可求得此时OP的长．解：作直径MN⊥弦AB，交AB于点D，由垂径定理，得AD＝DB＝12AB＝4cm.又∵⊙O的直径为10cm，连接OA，∴OA＝5cm.在Rt△AOD中，由勾股定理，得OD＝OA2－AD2＝3cm.∵垂线段最短，半径最长，∴OP的长度范围是3cm≤OP≤5cm.方法总结：解题的关键是明确OP最长、最短时的情况，灵活利用垂径定理求解．容易出错的地方是不能确定最值时的情况．

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.
