REMEMBER No Future in Time Clauses
Like all future forms, Future in the Past cannot be used in clauses beginning with time expressions such as: when, while, before, after, by the time, as soon as, if, unless, etc. Instead of using Future in the Past, you must use Simple Past.

Active / Passive Verb Forms
Sentences can be active or passive. Therefore, tenses also have "active forms" and "passive forms." You must learn to recognize the difference to successfully speak English.
In active sentences, the thing doing the action is the subject of the sentence and the thing receiving the action is the object. Most sentences are active.
[Thing doing action] + [verb] + [thing receiving action]
In passive sentences, the thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end of the sentence. You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. You can also use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action.
[Thing receiving action] + [be] + [past participle of verb] + [by] + [thing doing action]
Active / Passive Overview
Types of Verbs
Before you begin the verb tense lessons, it is extremely important to understand that NOT all English verbs are the same. English verbs are divided into three groups: Normal Verbs, Non-Continuous Verbs, and Mixed Verbs.
Group I Normal Verbs
Most verbs are "Normal Verbs." These verbs are usually physical actions which you can see somebody doing. These verbs can be used in all tenses.
to run, to walk, to eat, to fly, to go, to say, to touch, etc.
· I eat dinner every day.
· I am eating dinner now.
