新人教版高中英語必修3Unit 4 Space Exploration-Reading for Writing教學設計二
⑦在我看來, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

新人教版高中英語必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教學設計
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.

2、教學目標新教材對學習目標的分解是以“學生的全域發(fā)展”作為標準進行的，更注重了學生的主體性和目標的可操作性。學習目標首先被分解為“知識和能力”、“過程和方法”、“情感、態(tài)度與價值觀”。不僅解決了“學到什么”和“怎樣學習”的問題，尤其解決了“喜歡學”和“主動學”的問題。根據(jù)本節(jié)課的地位和作用，依據(jù)教學大綱以及學生的認知結構心里特征，我制定了如下目標：① 知識目標：根據(jù)具體情境學會用字母表示數(shù)； ② 能力目標：能用含字母的式子表示數(shù)量關系； ③ 情感目標：通過教學引導學生從現(xiàn)實生活經(jīng)歷與體驗出發(fā)，激發(fā)學生學習興趣，體驗用字母表示數(shù)的簡明性，培養(yǎng)學生的抽象思維能力和歸納概括能力 ④ 教學重、難點：學會用字母表示數(shù)，用含字母的式子表示數(shù)量關系。二、說教法“教必有法而教無定法”，只有方法得當，才會有效。根據(jù)本課教學內容的特點和學生思維活動的特點，我采用了觀察比較、順勢誘導、交流歸納的教學方法。
