Future tenses video lesson. In this lesson I am going to show you how to form a future tense and when to use a future tense.Take a look at these sentences:I will help you carry those bags.She is going to work tomorrow.She is flying to London next week.The bus leaves at six o'clock.The prices are about to go up.By this time tomorrow he will be lying on the beach.All of the sentences are in the future tense, but as you can see there is quite some variation.
