Did you know that all around the world, 3 to 6 billion trees are cut down each year? Have you eve r planted a tree?
Ask some students to try to answer and then the teacher says: So we should plant more trees every year to prevent natural disasters.
(设计意图：课前导入，用鲜明对比的图片欣赏活跃课堂气氛并且拓展学生视野，并在与学生交流的同时将话题引入新课，同时运用了本课时出现的新单词和重要词汇，在知识点和话题方面都为Comic strip 的呈现做了很好的铺垫。还引导学生认识到植树对环境保护的重要意义。)
Step 2 Presentation
1. Show pictures to present new words. Show a picture of “breadfruit” and ask: Do you think we should plant more such trees? Let students try to answer and tell them what it is.
(设计意图：保护环境种植“breadfruit”这种树有没有意义？顺便呈现新词breadfruit。)
2. Ask: What else can we do to protect the environment? Show more pictures to present new words: dig, wise, reduce, recycle, take shorter showers, turn off.
（设计意图：继续运用环保话题，将本课时会出现的新词全部呈现。）
3. Read the new words.
(设计意图：巩固新单词的读法。)
Step 3 Learn the conversation
Teacher：Do you think Eddie and Hobo like planting trees?
1. Listen to the tape and ask:
(1) Why does Hobo want to plant more trees?
(2) Does Eddie want to go with Hobo?
(3) What does Eddie want to plant?
（设计意图：设问检测学生是否理解对话，如果不能很好的理解，顺便给出学生解释。）
Listen to the tape and follow in chorus. Pay attention to your pronunciation and intonation.
（设计意图：让学生跟读录音，尽量模仿语音语调。）
Read the conversation, you can add your own ideas.
（设计意图：通过表演对话，调动学生记住对话中的句型。）
