One common way to talk about the future is to use a verb.
I want to watch 'Hulk' tonight.
I 'm planning to go to Spain next year.
I 've decided to learn Japanese one day.
Obviously, the verb (want, plan, decide) uses a present form. But the 'to watch' or'to go' or 'to learn' part means in the future.
Here is a list of common verbs for the future:
|to have a bath tonight.|
Another way to talk about the future is to use an expression with 'be ... + to + verb'
I 'm due to visit the dentist next month.
I 'm likely to be late tonight.
Here are some more future "be + _ + to + verb" structures:
|I am going to mark your homework.||a plan/intention|
|I am likely to mark your homework.||probably|
|I am bound to mark your homework.||almost definitely|
|I am expected to mark your homework.||people expect it|
|I am about to mark your homework.||I'll do it next|
|I am to mark your homework.||formal|
There are more examples of these in the other 'future' pages.
