北师大初中九年级数学下册二次函数y=ax2+bx+c的图象与性质1教案
解析：(1)已知抛物线解析式y＝ax2＋bx＋0.9，选定抛物线上两点E(1，1.4)，B(6，0.9)，把坐标代入解析式即可得出a、b的值，继而得出抛物线解析式；(2)求出y＝1.575时，对应的x的两个值，从而可确定t的取值范围．解：(1)由题意得点E的坐标为(1，1.4)，点B的坐标为(6，0.9)，代入y＝ax2＋bx＋0.9，得a＋b＋0.9＝1.4，36a＋6b＋0.9＝0.9，解得a＝－0.1，b＝0.6.故所求的抛物线的解析式为y＝－0.1x2＋0.6x＋0.9；(2)157.5cm＝1.575m，当y＝1.575时，－0.1x2＋0.6x＋0.9＝1.575，解得x1＝32，x2＝92，则t的取值范围为32＜t＜92.方法总结：解答本题的关键是注意审题，将实际问题转化为求函数问题，培养自己利用数学知识解答实际问题的能力．三、板书设计二次函数y＝ax2＋bx＋c的图象与性质1．二次函数y＝ax2＋bx＋c的图象与性质2．二次函数y＝ax2＋bx＋c的应用

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 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.
