English Grammar description

Containing four subjects simply composed:
- tenses
- passive form
- reported speech
- conditional sentence

A tense talks about the time of an incident. Focus on verb which is the predicate of sentence, you will automatically know what the tense is.

Passive form is used to give information in a different way. It sometimes doesn't tell who did what.

Reported speech or indirect speech SPEECH means reporting what people said without quoting their exact words.

Conditional sentence is used to say things which are not facts, situations which are true in certain circumstances or under certain conditions. This sentence usually contains "if clause".
