Future forms: will, be going to and the present continuous

Will and Won't

Will is used to express a future action or event that is not planned or decided at the moment of speaking. It implies a spontaneous decision or a prediction about the future. It is also used to make promises.

Example:

• "I will answer the phone." (spontaneous decision)
• "I think it will rain tomorrow." (prediction about future weather)
• "I will pay you back as soon as I can." (promise)

Won't is the contraction of "will not" and is used to indicate the negative form of the future tense.

Example:

• "He won't attend the meeting." (He will not attend the meeting.)
• "I won't do it again." (promise)

Present Continuous

The present continuous tense can be used to describe future actions or events that have been planned or arranged in advance.

Example:

• "I am meeting my friends for lunch tomorrow." (planned action)
• "She is flying to Paris next week." (pre-arranged travel)

Be going to

Example:

• "They are going to buy a new house next month." (planned action based on their decision)
• "Look at those dark clouds! It's going to rain." (prediction based on the evidence of dark clouds)
