What's an auxiliary verb ? - Why do we need them sometimes - and other times we don’t ? - Can we use them to emphasise things ? - How can we use them to show interest ? - Do we also use them to encourage the listener to respond ?- When can they help us to avoid repetition ? These are all the questions Marc will answer on this video lesson about the three main important auxiliary verbs (be, do, and have). He will provide examples to better understand them.
This lesson is intended for intermediate students who wish to improve their English grammar, and for those above levels who wish to clear up doubts about this topic.
