Answer:
The teacher begins with a sentence, for example 'If I go out tonight, I’ll go to the cinema.' The next person in the circle must use the end of the previous sentence to begin their own sentence, for example 'If I go to the cinema, I’ll watch Charlie and the Chocolate Factory.' The next person could say, 'If I watch Charlie and the Chocolate Factory, I’ll eat lots of chocolate.' Then, 'If I eat lots of chocolate, I’ll put on weight.' etc.
