教材分析
this is the third teaching period of this unit. to test whether students have grasped the important and difficult language points they learned in the last period, the teacher should first offer them some revision exercises. then lead in the new lesson.
this teaching period mainly deals with the grammar: learn the use of ought to and review the use of can, could, may, might, will, would, shall, should, must, can’t. students often feel modal verbs abstract and difficult, so it is necessary to make the lesson interesting and connect it with their daily life in order to let it easy to accept and understand. firstly, the teacher can ask students to read the reading passage come and eat here(1)again, tick out the sentences using modal verbs from the reading passage and translate them into chinese. secondly, compare and discover the uses of each modal verb by giving a lot of example sentences. thirdly, do the exercises in discovering useful structures on page 13 and more exercises for students to master the related modal verbs. finally, summarize the use of ought to and let students make it clear how each modal verb is being used in the situations.
at the end of the class, ask students to do the exercises in using structures on page 54 and additional exercises for consolidation.
