5、f this activity.a good listener should be able to predict according to some hints such as the topic, the questions listed, etc., to listen with the purpose of finding useful information and to summarize.later, let the ss listen to it.at the same time, teachers should design some simple questions.aft

6、er that, the ss have known some about the listening material, and then teachers can ask them to listen to it again to be ready for more difficult questions.if necessary, the ss can be given another time to listen.while practicing, teachers had better give students some advice on how to do it well.ce

7、rtainly, suppose there are many new words and expressions, teachers deal with them firstly.after practicing listening, the ss are expected to learn some expressions about imagination. the topic is about what life will be like what life will be like in your hometown in 1000 years' time.later let
