The basic aim for this, is for students to interview each other in pairs and then present their findings to the class. For beginners this activity is great to find out about their family or their personal biography, their native country etc. It is a great for intemediate students to practise using different tenses. For example you can find out about holidays, life events childhood or their future plans. Finally, for advanced students it could be adapted into a murder mystery or a plan for an imaginary problem. This way, students can practice using more complex structures.
