 Future - Will 
In the previous lesson (L2U2L1), we learned about the future using (be) going to. Another way to talk about the future is with will + verb. The verb is in its base form, or infinitive. Just like (be) going to, we use will to talk about predictions or future plans. For example: I think it will rain today.
I will visit you next week. We also use will when we decide to do something at the moment of speaking. For example: That's too hard for you. I'll help you. We use (be) going to when we talk about things that were already decided or planned. For example: They’re going to come on Tuesday. We generally use future time expressions at the beginning or end of a sentence. Remember to use a comma (,) when the time expression is at the beginning of the sentence. For example: Next year, I'll study geography.
To make a Wh- question, add the Wh- word at the beginning of the Yes/No question. For example: When will we sing songs? Who questions are different because who is already the subject. For example: Who will sing songs? | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
