The simple future tense is used:

• to talk about things that are likely to happen in near future e.g. The train will leave at 5 o’clock.
• to offer to do something e.g. I will prepare lunch today.
• to tell what will happen in a given situation e.g. If you drop this, it will break.

Hence, we use will+verb to express simple future. Shall+verb is generally used with the first person pronouns (I, we).

However, when we talk about events which are sure to happen in future, we use simple present/present continuous and the form ‘going to’.

e.g. She is leaving for Dubai on Saturday.

The bus to Pratap Nagar leaves at 10 p.m.

My mother comes back home at five. You can wait if you want to.

We are going to ask the principal for a change in our time table.

The Future Continuous tense is used to talk about events that will be in progress at some point of time in future. We use will+be+verb+ing to express future continuous.

e.g. I will be waiting for you at the hall at around 9 p.m.

I will be preparing for my test tomorrow evening.
