Learn English Grammar with 6 Minute Grammar from BBC Learning English! In this episode, we look at the phrase 'used to' which we use when we want to talk about something we did regularly in the past, but we don't do now. We also use it to talk about a past fact which is no longer true. In 6 Minute Grammar, Neil, Catherine and Rob share their pasts with you and give lots of examples of 'used to'. You'll find a quiz on our website: http://www.bbc.co.uk/learningenglish/english/course/lower-intermediate/unit-17/session-2/activity-2 0:00 Introduction 0:37 'Used to' 2:50 'How to use 'used to' in the negative 4:00 Making questions with 'used to' 4:46 'Used to' quiz If you liked this video, you can discover more of our lessons here: How to use the Past Simple: https://youtu.be/PgsG98vByiw Grammar: How to choose the correct tense in English: https://youtu.be/GiI3wjFWSXQ Past simple and past continuous: https://youtu.be/uTB5I8V9Eog #6MinuteGrammar #BBCLearningEnglish #LearnEnglish
