Talking about Decisions that Have Been Made by Others
The ～ことになる pattern is similar to the ～ことにする pattern that we learnt in Year 12.
- With ～ことになる, the decision is not necessarily made by us.
- Or, the decision could have been forced on us by circumstances beyond our control.
- We may not know who made the decision - it's could just be the way things are.
- There are few jobs in my town, so I've had to move to a bigger town.
In the example above, the sentence ends in the past tense because the action was a one-off and has already taken place.
- At my school, classes on Wednesdays finish at 2 o'clock.
In the example above, the sentence ends in the present continuous tense because the action is ongoing. i.e. Classes end at 2 every Wednesday.
- (It has been decided that) we will sit our university entrance exams in November.
In the example above, the sentence ends in the present continuous tense because although the decision has been made and continues to affect us, the action has not yet taken place.
