DIRECT AND INDIRECT SPEECH

Direct speech refers to reproducing another person’s exact words or saying exactly what someone has said (sometimes called quoted speech).

Here what a person says appears within quotation marks ("...") and should be word for word.

For example:

She said, "Today's lesson is on presentations."

or
"Today's lesson is on presentations," she said.

TENSE CHANGE

• When reporting speech the tense usually changes. This is because when we use reported speech, we are usually talking about a time in the past (because obviously the person who spoke originally spoke in the past). The verbs therefore usually have to be in the past too. 
  
  
• Note : the reporting verbs that are usually used to report imperative sentence are

:Tell , other command , ask , warn , remind.

Example :

Present simple
Past tense
direct     : Febri said “ I watch TV”
indirect   :Febri said that  he watched TV.

Past simple
Past perfect
direct    : Faizal said “ I went to Cinema yesterday”
indirect  : Faizal said (that) he had gone to cinema     the day before.

Future simple

indirect  : Mangku said (that) he would buy a car the     week after.
