[Future time] Future progressive

1. 確信某事肯定會發生

When I arrive at the airport, my whole family will be waiting for me.

I shall be traveling this time next year. (來去動詞：現在進行式代替未來式)

2. 預則或希望某事發生

When I get home, my wife will probably be watching TV.

I hope it won't still be raining when we have to go to shcool.

3. 詢問別人的安排，特別是當你想得到別人幫助的時候

Will you be passing the post office when you're out?

Will you be using your bicycle tomorrow morning?

Mary will be sleeping when I arrived.

I will be dating my friends at 8 tomorrow morning.
