1.Would you please tell me what the different between Future simple & Future perfect simple is ?
Ex. If I say " I will go home before 6.00 am and " I will have gone home before 6.00 am
You use the future perfect if there are two events in the future, and you want to refer to the earlier one from the point of the view of the later one.
A: I will make breakfast at 6am. (the later event in the future)
B: How? You're not even at home.
A: I will have gone home before 6am. (the earlier event in the future).
A: I'm going Paris next year. (the later event in the future)
B: You can't afford to go to Paris.
A: I will have saved enough money by next year. (the earlier event in the future).
You can see that there's an analogy with the
past perfect, which you use when you want to refer to two events in the
past, one before the other.
