Present Perfect Simple and Continuous sentence completion

Give students 10 to 20 sentences stems that most of them will be able to complete with true sentences, e.g. “I’ve been studying _____________“. They should fill in the missing parts of at least half the sentences to make true statements about themselves. They then read out just the parts they have written, and their partners try to guess which sentence they wrote that for. For a much more challenging extension, they can then write some whole true sentences about themselves and get their partners to guess the first half of the sentence when they read out the last few words.
