This is a power point presentation made in order to train students who are studying for one of the sections of the speaking part of the cambridge exams (FCE and CAE). It has several pictures that they have to describe and compare, and questions about the pictures. They have to answer the first question in one minute, and there is a second question thas has to be answered in thirty seconds (just like in Cambridge exams). I hope it's as useful for you as it has been for me.
