Explanation:
The English language offers different possibilities to speak about the future. The choice depends on the meaning and intention of the sentence.
These forms are the most common:
1. Although we use the Present simple to express actions in present, we can use it to express the future when we talk about timetables, schedules, etc.
e.g. The train <u>arrives </u>at 12:30.
2. When we talk about future actions in the present, we will use the construction<em> to be going to</em><em>:</em>
e.g. I<u> am going to see</u> my mother in April.
3. When we talk about some fixed arrangements or appointments in the future, arranged before the present time, we will use the Present continuous:
e.g. Paul <u>is flying</u> to London on Monday morning.
4. We use the <u>will + infinitive</u> form to express certainty, habitual characteristics, willingness, and instant decisions:
certainty: e.g. It <u>will snow</u> in Brighton tomorrow evening
habitual characteristic: e.g. We <u>will wait</u> in the shelter until the bus comes.
willingness: e.g. You’re carrying too much. I<u> will open</u> the door for you.
instant decisions: e.g. Wait! I <u>will drive</u> you to the station.
5. We use the<em> will + be + -ing</em> form to a situation that began before a future time point and continuing through that time point:
e.g. When you get off the train, I <u>will be waiting</u> for you by the ticket machine.
6. We use the<em> will + have + past participle</em> form to talk about a future action completed before a later future time:
e.g. When they get married in March, they will have been together for six years.
