This teaching period mainly deals with the grammar:learn the use of ought to and review the use of may ,might ,will,would,can ,could,shall,should and must.Ss 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.The teacher can ask the Ss to read the text Come and Eat Here(1) carefully and learn the words and grammar from it.summarize the use of ought to and let Ss make it clear how each modal verb is being used in the situation.
