Simple Future
The simple future tense is used to talk about actions we believe will happen in the future, we normally mention plans, predictions, expectations, and other possibilities with this tense. It is important to consider that even if we believe we know and express in words what will happen in the future with certainty, we cannot control what actually ends up happening. The simple future may be formed with the modal verb -will or the structure "be going to".
This tense is used to:
1) To talk about actions that will start and finish in the future.
2) To make predictions.
3) To talk about facts.
4) To talk about abrupt decisions.
5) To make promises.
6) To give orders and to make requests.
7) To talk about refusals.
8) To talk about the immediate future with the phrase "be going to".
Time Expressions
The simple future tense is often used with future time expressions. However, it is not necessary to always mention a future time expression when using a future tense if the context of the future was already established by a previous statement or question in a conversation.
Formation - Affirmative Statements & Questions
Affirmative statements in the simple future tense are formed with the modal verb -will followed by the infinitive form of a verb, modal verbs are not conjugated depending on the subject and they have their own negation and question forms that do not require the verb -do. There is also a second way to form the simple future tense in English with the structure "be going to" followed by the infinitive form of a verb, this phrase does require the verb -be to agree with the subject, it is used more in conversation and is generally more informal. The modal verb -will is generally more appropriate when expressing facts while the structure "be going to" is more appropriate when expressing decisions and intentions. The structure "be going to" is also used in the past tense ("(was / were) going to + infinitive form of a verb") to talk about actions a subject intended to take but ultimately did not and for talking about predictions made in the past about the future. Questions are formed by placing the modal verb -will before the subject followed by the infinitive form of a verb, alternatively questions may be formed with the structure "be going to" in which case the verb -be is placed before the subject followed by "going to" and the infinitive form of a verb.
