Step 2 Presentation
1a. To introduce Ss to the unit goal, talk about pollution and environmental protection.
Picture:
The pictures show different forms of environmental pollution. The first picture on the left shows an airplane flying over some houses. The airplane seems to be flying a quite a low altitude, so the noise level must be quite high foe the people living in these houses. This is considered noise pollution. The second picture shows some vehicles give out exhaust fumes and causing air pollution. In the third picture, we see big chimneys giving off a lo of smoke and polluting the air. The last picture shows a rubbish dump hat pollutes the environment around it.
What other things cause pollution?
Ask Ss to complete the activity as a class, then work in pairs to think of more words to add to the lists for each column.
1b. To help Ss recognize the target language in natural speech.
Everyone needs to play a part:
In the conversation, the boys are talking about the river in their town being polluted by litter and industrial waste. One of them wants to write to the government about the problem, but the other boy wisely says that cleaning up the river is everyone’s responsibility, not just the government’s.
Predicting the answers
Ss work in pairs to predict the answers to the activity, then play the recording for Ss to fill in the gaps and review answers as a class.
1c. To give Ss guided practice in using the target language to talk about pollution and environmental protection.
