We have learned many kinds of natural disasters such as Tornados, hurricanes and earthquakes, and we know that we can’t stop them from happening, but we can reduce the damage they bring by studying them.

Step 6 speaking-- Group work
We have learned from the previous class that some European countries are better than us at looking after the environment. It’s high time for us to realize the importance of protecting our planet and do something that is actually helpful. Now please turn to Page 37, look at Speaking 2, Exercise 1, let’s discuss how the things in the first box are bad for the environment, using the words in the second box to help you. Using “We need to…”, “We must…”, “We should…” to discuss solutions. Divide the class into groups of four to discuss in the charge of the group leaders. Each group chooses only one of the five topics. While they are discussing, the group leaders keep records. After about ten minutes, ask two group leaders to give a short talk about their discussion to the class.
