GIVING INSTRUCTION

   Identification : Expression that is used in order that other person does

  what we instruct or request.

   The differences between request and instruction

1)     Instruction (also called imperatives) :

Instruction require the person receiving them to do something, or to stop doing it. Instructions are directly addressed to the person who has to do them. Therefore, instruction are one of the few types of English sentences that do not need a subject. The subject is usually “you” (understood).If there is any doubt who should do the instruction, the “naming” form-the vocative is used.

2)     Request :

Request are often question, though indirect request may not be. Sometimes an instruction is changed into a request by the addition of “please” or a question tag. To make a request more polite we might use the subjunctive form of the verb. Very often English request are indirect. Instead of asking someone to do something, the speaker asks if the person is able to do it. Therefore  modals of ability (“can”, “may”, etc) are very often.  

   Example :

Tiwi   : Rio, come here please !

Rio    : OK, what’s up ?

Tiwi   : Help me move the box please !

Rio    : Sure, where I can to put this box ?

Tiwi   : In there, on the table behind the cupboard.

Rio    : OK, let’s go.
