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: modal verbs—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 make it easy to accept and understand.
