The future tense is used when talking about something that will happen in the future, though the “be going to” form of the “future modal” is usually used for things that have already been decided.
The future tense is formed using two “modals”: “will” and “be going to” (see MODALS in the Grammar Corner”). For negative and positive sentences, the modal is placed before the base form of the verb.
“George will leave for Paris next week.”
“I am not going to play golf tomorrow.”
For questions, place “will” or the correct form of “be going to” in front of the subject and the base form of the verb, after the subject.
“Will the trees be cut down in the spring?”
“Are Mike and Ryan going to sing at the concert?”
