The English language has many ways of making requests. The most common involves using the IMPERITIVE and MODALS. See the examples below:

Using the IMPERITIVE:

The IMPERITIVE is the most simple form of the verb. When used, the subject of an IMPERITIVE SENTENCE is understood to be "you", although it is not usually spoken.

Open the door.Will you help me? Yes, I will.Pick up your toys. Please help me.

(You) open the door.You help me.Yes, I will (help you). (You) pick up your toys. (You) please help me.

The IMPERITIVE is often used by persons in authority when speaking to subordinates, e.g. a parent to a child.

Using MODALS:

To show respect and politeness, most people use modal expressions when making requests.
