Final answer:
In the examined sentences, we apply the rules of 'going to' for planned actions and likely results of current situations. Corrections include changing 'thousands are starving' to 'thousands are going to starve' and 'Dave's being very disappointed' to 'Dave's going to be very disappointed'.
Step-by-step explanation:
The sentences provided appear to address how actions in the future are conveyed using present continuous tense or 'going to' for future plans and intentions. Through careful examination, corrections can be made:
- Present continuous is typically used for arranged events or plans in the near future.
- 'Going to' is utilized for future intentions or plans that are decided before the moment of speaking.
The corrected sentences using these concepts would be:
- I'm tired. I am going to go to bed.
- Unless aid arrives within the next few days, thousands are going to starve.
- There are going to be more of us at the picnic than we thought.
- I can't get to the match after all, that's a pity. Dave's going to be very disappointed.
It's important to note that the second sentence is corrected to 'are going to starve' to indicate a future result of a current situation, and the fourth sentence is changed to 'Dave's going to be very disappointed' to reflect a future state based on the present circumstances.
