Examples of Future Plans and Intentions
1. Use for future plans. Future plans are decisions that have been made before the moment of speaking.
Example:Are they going to work on development-related projects in India? Look at that writer. He's going to autograph his novel. I'm going to develop a mailing list by the end of the summer.
2. Use to predict an action that you see is about to happen:
Look at that writer. He's going to autograph his novel.
Look at the President. He's going to turn to diplomacy.
3. Use to express intentions for the future. This form is similar to future plans. However, future intentions are more general in nature.
She isn't going to volunteer for the managed project.
This politician isn't going to help the disadvantaged.
