Give me some example of things that can deteriorate Give students handouts and ask them to listen and match the word in A with the most suited option in B. Demonstration: do the first one together as a whole class. Ask them to match the rest individually. For feedback, they first do pair check, then listen again to check, then give them answer key. As a second step, give them the tapescript and to underline the words and phrases that helped them find the answer.

Give students handouts and do the first sentence of the first exercise together as a whole class then ask them to finish the rest of the sentences individually. Instruction: Tell them that they're working in groups and that each group will work on only one text. ICQs: Are you working in pairs? Are you going to do all texts? After they're finished, ask them to stand up and mingle to ask and finish the rest of the texts from their friends.

Ask Ss to work in groups and put the charts using the projector. Tell them that these charts are related to Tunisia and ask them to choose 3 topics to talk about using those charts to either indicate that the number has risen/fallen... Inform them that they can use sentences similar to the matching exercise. Hand them some papers to write down their thoughts and give them 2 minutes to gather some thoughts about the chosen topics individually then have them discuss them. If there's time, make the groups mingle and talk to other groups about their opinion regarding the common topics.
