·       Point to the first sentence on the board and say:

      It is possible that it will rain tomorrow and that I will stay at home. So we say If+ present + the future

·       Point to the second sentence and say:

      But in this sentence , it is not really possible that the extra cases will occur. It is hardly possible                  because we already have an agreement. So we say If + past + would.

·       S look at the first pic on PB/P43, Ask: Do you think this will happen? no . Why? Because you can not go to the sun by bicycle. S read the example next to the pic.

·       S look at the second pic. Ask: Do you think this will happen? no. Why not? Because people don’t throw glasses to break them. S read the example next to the pic.
