解析：(1)已知拋物線解析式y(tǒng)＝ax2＋bx＋0.9，選定拋物線上兩點E(1，1.4)，B(6，0.9)，把坐標(biāo)代入解析式即可得出a、b的值，繼而得出拋物線解析式；(2)求出y＝1.575時，對應(yīng)的x的兩個值，從而可確定t的取值范圍．解：(1)由題意得點E的坐標(biāo)為(1，1.4)，點B的坐標(biāo)為(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.故所求的拋物線的解析式為y＝－0.1x2＋0.6x＋0.9；(2)157.5cm＝1.575m，當(dāng)y＝1.575時，－0.1x2＋0.6x＋0.9＝1.575，解得x1＝32，x2＝92，則t的取值范圍為32＜t＜92.方法總結(jié)：解答本題的關(guān)鍵是注意審題，將實際問題轉(zhuǎn)化為求函數(shù)問題，培養(yǎng)自己利用數(shù)學(xué)知識解答實際問題的能力．三、板書設(shè)計二次函數(shù)y＝ax2＋bx＋c的圖象與性質(zhì)1．二次函數(shù)y＝ax2＋bx＋c的圖象與性質(zhì)2．二次函數(shù)y＝ax2＋bx＋c的應(yīng)用

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.
