Section A Grammar Focus 4a-4c Analysis of teaching materials The topic of this lesson is about inference. The teaching target is to learn the inferential function of modal verbs. There are three exercises on the text book. In 4a, students need to choose modal verbs to deduce the facts. In 4b, students need to use modal verbs like “must, cant, could and might” etc. to finish the sentences. In 4c, students need to discuss with their partners about what kind of person the rooms owner is based on the picture by using the modal verbs which could be used to deduce the fact.

Analysis of students The students of Class 12, Grade 8 are aged from 14 to 15. They are studious, active and interested in diversified activities. Before this lesson, they have known the meaning of “must, cant, might and could”. Besides, students show great interest in joining the TV show “Whos the murderer”. So they want to get involved in this class. However, they dont know how to use modal verbs to deduce some facts. Therefore, they need the teachers help with the inferential function of modal verbs. Knowledge aims 1. To understand the inferential functions of modal verbs “must, cant, might, could” 2. To be able to use modal verbs “must, cant, might, could” to make inferences in different tenses. 3. To use general questions starting with can to make inferences. Teaching aims Ability aims To be able to use modal verbs to deduce something happened. Moral and affective aims To cultivate students deducing ability based on some clues. Important points 1. To understand and practice the inferential use of “must, cant, might, could” 2. To know “must, cant, might, could” can be used in different tenses to make inferences. 3. To employ general questions to make inferences. Difficult points To know “must, cant, might, could” can be used in different tenses to make inferences. Teaching methods Task-based teaching approach, demonstrative approach Teaching aidsForclass teaching app，whiteboard , video clips, worksheet Teaching Procedure Teaching steps Teachers activities Students activities Design purpose Lead-in Video display(1min) Show a video sent by Bai Jingting. Knowing students in Zhuhai No.13 School are insightful, he wants some students to join in their group in the TV show “Whos the murderer”. To be able to join Bai Jingting, students have to finish 6 tasks to prove they are good at deducing facts. Ss watch the video and know they have to finish 6 tasks to join Bai Jingting. To create a scenario to ignite Ss interest in this lesson 1.Brainstorm (2mins) Ask Ss to observe the inferential usage of modal verbs“ must, cant, could, might” through some sentences.

Students choose one picture and play the game by answering questions. To liven up the atmosphere and enhance these four modal verbs in different tenses to make inferences through exercise, getting Ss fully involved in class. Task 3 Have a deducing test. Listening（3mins） Show a picture of the chatting between Bai Jingting and teacher.

And the other three students stay in the group to answer questions from other groups. After the clue- searching procedure, the group work together to finish the information card and the portrait of the suspect X. 1) To develop their cooperative, speaking and deducing ability. 2) To further enhance Ss knowledge about how to use general questions to make inferences. Task 6 Write a report about the suspect X. Writing about the suspect X（4mins） Have Ss to write down different statements said about the suspect based on the clues they have found out during the group work. 1) Using the modal verbs with inferential functions to write down the information about the suspect X with the clues on their work sheet. 2) Present the writing.
