HOMEWORKHOMEWORK Unit 7 Whats the highest mountain in the world? （Section B 1a-1d）Teaching Design . The Guiding Ideology and Theoretical Basis As we know that the principles of communicative class can be reached only when teachers create appropriate experiential scenarios. And the teaching unceasingly establishes the classroom instruction situation, take the question as the master line, guides the student to cause suspicion, the question and answer, stimulates the student creative thought ability, is helpful smoothly achieves the teaching goal to the teacher. Psychology demonstrate, pleasant learning can also prove to fully arouse students interest in learning, enthusiasm and play the potential of students, thus increasing memory effect. And the training aim in English teaching is to cultivate students not only to master fundamental language skills, but also to use foreign language to achieve communication. Let the student carry on the spirited language practice, enhances enthusiasm which the student studies. The goal of Go for it! is to make language learning motivating and successful through a step-by-step progression that builds confidence and lead to open-ended activities where students can actively relate learning to their personal lives. . Analysis of Materials Section B in Unit 7 has changed the topic from the comparison of nature and culture to animals. This part introduces something about elephants, pandas and panda research base. Through listening, speaking, reading, writing and other activities, the teacher can guide students to learn more comparative sentence structures. On the one hand, the contents in la-le consolidate the fact description with numbers. On the other hand, it expands more sentence patterns such as multiples to compare two different things. In activity 1a, it shows some information about an elephant and a panda, and students are supposed to compare them with comparative sentence patterns. Meanwhile, it also foreshadows the groundwork for later listening. In activities 1b and lc, the listening material is mainly about the description of baby pandas with length, weight, color and so on. In activity 1d, students are supposed to take turns telling something about pandas. In emotional education, the teacher should guide students to understand why and how to protect the endangered animals such as the giant panda. After much deliberation, I design this language learning, speaking and writing class based on the latest English Curriculum Standard. . Analysis of Students Since this is the second part of this unit for Grade Eight, the students have been stimulated to talk about the comparison of nature and culture. And Ss also could describe pandas based on what they saw at the zoo. However, not all of them have known the details, especially the baby panda. In emotion education part, the teacher can guide them to think why and how to protect them. In order to help students grasp the key points well, I will use the following steps. First, the clear learning objectives help students to monitor their own learning. Next, provides step- by-step language support for students to follow. Then, activities encourage learners to contribute their own ideas and feelings and to be active in class, and develop students language system. . Teaching Objectives 1. Knowledge Objectives: To get to know the useful words and expressions weigh, at birth, adult, up to + many times +comparative + than + 2. Ability Objectives: To improve the English listening skills. 3. Emotional Objectives: To know more about pandas and try to protect them. . Key and Difficult Points 1. Key points Get to know the useful words and expressions weigh, at birth, adult, up to Improve Ss English listening skills. 2. Difficult points Use this sentence pattern “ + many times +comparative + than + ”freely. Finish a writing about panda. . Chart of Teaching Process . Teaching Procedures Step1.

S1: The Yangtze River is about 6,300 kilometers long and it is the longest river in China. S2: The Yellow River is 5,464 kilometers long and it is the second longest river in China. T: So, that means Ss: The Yangtze River is longer than the Yellow River. S3: The Great Wall is the longest wall in the world.

Make a set of sentences in group and then share in class. T: Lets see what we should learn in this class. Here are the learning objectives. By the end of this class, we will be able to 1. Get to know the useful words and expressions like these. weigh, at birth, adult, up to(lead Ss to read) + many times +comparative + than + (give examples and help Ss understand the word comparative) 2. Improve my English listening skills. 3. Know more about pandas and try to protect them. T: Are you clear? First, lets look at two animals and make sentences according to the given words. T: Look at the first one, who can say? S1: This elephant is 350 cm tall. T: Great. So, how about this panda? S2: This panda is 150 cm tall. T: So, which one is taller? Ss: This elephant. T: Now, can you use than to make a sentence about it? S3: This elephant is taller than this panda. T: 350 minus 150 is Ss: 200. T: And we can put 200 meters before taller, so the sentence should be S4: This elephant is 200 cm taller than this panda. T: Do you agree? Ss: Yes. T: How about these ones? S1: This elephant weighs 5,000 kilos. T: Great. How about this panda? S2: This panda weighs 100 kilos. T: So, which one weighs more? Ss: This elephant. T: Now, use than to make a sentence. S3: This elephant weighs more than this panda. T: Do you think so? Ss: Yes. T: Thank you. How much is 5,000 divided by100? Ss: 50. T: We can say 50 times. The sentence should be S4: This elephant weighs 50/many times more than this panda. T: Do you agree? T: Next ones. Make a sentence, please. S1: This elephant eats 150 kilos of food a day. T: OK. How about this panda? S2: This panda eats 10 kilos of food a day. T: So, which one eats more? Ss: This elephant. T: Use than to compare them. S3: This elephant eats more than this panda. T: Do you think so? Ss: Yes. T: Thank you. How much is 150 divided by10? Ss: 15. T: We can say 15 times. The sentence should be S4: This elephant eats 15/many times more than this panda. Step3. Practice (group work) 1. Make a set of sentences in group of four. 2. Ask some groups to share their sentences. T: Now can you compare two things or persons like this?. Please work in groups and make a set of sentences. (practice in group work, then ask some to share) T: OK, stop. Which group want to show first? S1: China has over 5,000 years of history.
