3,students need to catch the main idea and find out the topics they have heard in the conversation,otherwise they cannot choose the right answer.At the same time they can also have a good understanding of American culture and customs in different social occasions of communication.If we see Activity 3 as trunk of a big tree,Activity 4 will be branches.That is to say,each piece of advice in Activity 4 embodies one of the topics in Activity 3.This activity requires students to listen carefully and understand the conversation fully and deeply in order to catch as many details as possible.Maybe they need to pay much attention to how to ask for and give advice correctly.So this helps students be well prepared to study the Function part.

　　Function

　　The function of this module is about "giving advice".Students are demanded to master how to use the modal verbs "should" and "must" to give advice.This part contains two activities.In Activity 1 students need to look at the sentences in Listening and Vocabulary Activity 4 and try their best to learn when and how to use the modal verbs "should" and "must" by using them to complete the following four sentences.Meanwhile this activity also lays a good foundation for Activity 2.Activity 2 not only practices the use of the modal verbs "should" "shouldn't" "must" and "mustn't" but also is linked to the theme or topic of this module-different cultures as well as different customs.Deeply speaking,it both develops and improves students'language skills and increases and broadens their cultural knowledge.

　　Speaking
