9、iding 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 stude

10、nt 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

11、 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 th

12、e 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

13、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 structur

14、es. 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 comp

15、are 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 tel

16、ling 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 Stan

17、dard. . 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, especia

18、lly 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-

19、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. .
