Future tenses, which we speak about in the Unit 8, as for me much bigger fun than other tense.
We don?t speak any more about boring routines and habits, weather we have them now or used to have many years ag.
We live in a future, making plans, dreaming and predictin.
Lessons about future tenses naturally cause less boredom among the student.
But as much as the future tenses grammar lessons can be interesting and fun, they can be confusin.

1. Due to wide range of the future tense structures the problem which one to choose can occur, especially while using mixed future forms choosing between Future Simple, Present Simple/ Continuous future functions and ?to be going to.
Difference between all of them can be shown by telling the story of for example John, who wants to marry Sue and says ?Will you marry me?.
He is not sure about her answer, so he uses ?will.
Sue says ?Yes, I will? and by that gives John a promis.
Now, their future is more clear and they say to parents that they are going to marry each other, so to say they have a pla.
Two months later they make an announcement to their friends that they are marring each other on August
18. They have a definite arrangemen.
The day before their wedding, John says his schedule to a friend ?Tomorrow I marry Sue and the next day we go to our honeymoon.

2.It is important to remind students of is that unlike the other simple tenses, English does not use a future form twice in most sentence.
The future form is used in the independent clause and the simple present is used in the dependent clause ?When I come to my home town I will meet all my friends.

3. All three Perfect tenses connect two different time.
The complication with the Future Perfect is that it can connect the present and future, past and future, or two future time.
For example,the starting period of ?I will have finished the next hundred pages by Christmas? is only obvious from context or an added time expression and otherwise the starting point of the writing could be before or after speakin.

4. While confusing between Future Perfect and Future Perfect Continuous, as always the teacher should highlight Future Perfect's emphasis on the results of completed action in the future and Future Perfect Continuous? stress on the action?s duration in the futur.
