 Another way of expressing the future tense is by what's called the going to future tense. Here we have our examples of they are going to watch, they are not going to watch, and the question are they going to watch? Here the important words are the helping verb to be conjugated appropriately based upon our subject. We've got the word going, the word to, and the base form of any verb that follows. To add the negative we'll put not in between are and going, and again to make the question we'll invert the subject and the helping verb resulting in are they going to watch. There are two usages for the going to future tense, and they are as follows. To indicate future plans with intentions that have been decided upon before speaking. We could for example say they are going to watch a film. I know that they've decided to go watch a film and I want to make a statement about them, I can say they are going to watch a film. Or we can have predictions, but this time the predictions are actually based upon evidence. Here I could see black clouds building in the sky coming towards me, and I might say something like it's going to rain.
