- predict a future situation
e.g. She will pass the exam
e.g. I'm sure you will enjoy the trip
e.g. The plane will be late since it always is.
Often we add "perhaps","maybe"，“prbably","possibly","I think" to make the belief less certain.
e.g. Maybe it will be ok.
e.g. He'll possibly find out when he sees Jenny.
2.future as an inevitable fact
e.g. I'll be thirty next month.
- a spontaneous decision
e.g. There is no buses today.Ok,I'll take a taxi.
補充：will與be going to的區別
be going to :decision made before the moment of speaking(表達一種計劃和意願）
e.g. I'm going to take a holiday after I finish the project.
一般現在時表示將來：timetable future
e.g. The train leaves at 6:00,so we must be hurry.
e.g.The summer holiday starts next week.
現在進行時表示將來：definit future arrangement.
e.g. Are you seeing Jane tomorrow?
e.g. What are you doing this Saturday evening? Are you guys playing?
