The simple future tense is a verb tense that is used to refer to the future.  This tense is commonly formed with the use of will and shall for an activity that takes place in the future. Besides these two auxiliary verbs, there are other ways that can be used to act as simple future tense as shown here.

Will / Shall
Will/shall + base form of the main verb
Will
 and shall are auxiliary verbs used mainly in the future tense. They are followed by the base form of a main verb. Shall has always been used in place of will for the first person singular (I) and plural (we), but will is becoming more common.

Examples:

  • will call you.
  • We shall have a discussion in three days’ time.  
  • shall arrive before noon. / They will arrive before noon.
  • I shall be away tomorrow. / We shall be away tomorrow.

 

Both will and shall have their contracted forms in ‘ll, and the contracted negative forms are won’t and shan’t.

Examples:

  • I’ll be free for a week. / I won’t be free for a week.
  • We’ll talk about it now. / We shan’t talk about it now.  

 

The negative form is not repeated if it appears again with another main verb.

Examples:

  • No: I won’t talk and won’t ask her about it.
  • Yes: I won’t talk or ask her about it.

 

Won't and shan’t are used to show unwillingness or refusal to do something.

Examples:

  • I have asked the noisy children to keep quiet, but they won't listen.
  • I shan’t make any payment until I receive all the goods.

  1. Be going to

Be going to + base form of main verb
Intention, decision, plans or arrangements already made to do or not to do for the near future prior to the time of speaking. 

Examples:

  • We are going to visit the zoo on Sunday.
  • We are going to move to a new neighbourhood next month.
  • We are not going to look for wild mushrooms this weekend.

 

Prediction of an outcome based on current situation.

Examples:

When be going to and will are used to make predictions, they mean the same.

  • He thinks his son's team will win the match.
  • He thinks his son'e team is going to win the match.

 

Be going to and will are used to describe future situations or actions, and they often convey the same meaning.

Examples:

  • My son is going to be ten month. 
  • My son will be ten next month. 
  • We are going to leave as soon as he arrives.
  • We will leave as soon as he arrives.
  • We are going to get something at the corner shop when it stops raining.
  • We will get something at the corner shop when it stops raining.

 

When the speaker is absolutely sure about something, he can use will or be going to.

Examples:

  • will be at the meeting tomorrow.
  • am going to be at the meeting tomorrow.
  • will probably be at the meeting tomorrow.
  • am probably going to be at the meeting tomorrow.

 

Sometimes be going to and will express different meanings.
Be going to is used to indicate a plan made before the time of speaking while will expresses a decision made at the time of speaking.

 

Examples:

  • We are going to visit Jill in the hospital tomorrow.
    (When we came to know that Jill was admitted to the hospital, we arranged to visit her the next day [tomorrow] - a prior plan.)
  • It is getting late. We will leave now.
    (The speaker decides to leave the moment he realizes it is getting late - a sudden decision.)

 

When a decision or plan is made for the distant future, will is usually used, while going to is usually used when a plan is made for the near future.

Examples:

  • She will get married in two years.
  • We are going to visit them again early next month.

 

We use be going to when there is an intention to do something and will for additional information.

Examples:

  • It's their twentieth wedding anniversary. They are going to have a celebratory party. (NOT: They will have a celebratory party.) They will invite about a dozen close friends. The friends will include two politicians.

 

  1. Be to

Be to (= is/are) + base form of main verb
Be to
 refers to an action that is to take place in the future, such as an obligation, arrangement, information, duty, instruction. However, other forms of usage indicating what will happen are possible.

Examples:

  • was just about to eat my dinner when the phone rang.
  • The workers were just about to leave their workplace when the fire started.

 

5. Simple present tense
The simple present tense is used for the future when we refer to something that has been scheduled or arranged to happen at a particular time such as a timetable.

Simple present tense and present continuous tense
Both the simple present and the present continuous tenses can be used to refer to the future.

Examples:

  • They have a drinking session next Sunday.
    (The simple present tense indicates the drinking session occurs every Sunday.)
  • They are having a drinking session next Sunday.
    (The present continuous tense indicates a drinking session next Sunday; perhaps, not every Sunday.)

The present continuous tense is used in questions about future plans.

Present continuous and be going to
Present continuous tense and be going to can have the same meaning as used here to describe actions that are planned or arranged for the future prior to the time of speaking. Will is not used here.

Examples:

  • I am going to watch my favourite TV programme this evening.
  • I am watching my favourite TV programme this evening.
  • He is going to attend a seminar tomorrow.
  • He is attending a seminar tomorrow.

 

Not be going to with go 
It is not incorrect to construct a sentence with be going to with the verb go. Use the present continuous tense instead as it is more commonly used.
 

Examples:

  • Not: They are going to go fishing this weekend.
  • Yes: They are going fishing this weekend.
