There are various types of auxiliary verbs. Generally, we call them helping verbs, but, in particular, linking, helping, and modal verbs. Modal auxiliary verbs are used in conjunction with verbs to express the mood of the total expression. In short, they are used to express possibility, request, duty, order, etc. Here, I am going to answer – how to use would and should modals auxiliary verbs.
Would modal verb
It is used to express –
For desire–I would like to….
•I would like to live in a world where poverty is totally absent.
•We would like to visit Antarctica.
• You know my goal. I would like to be a leader.
In this way, you can express your desire. It is like desire-driven imagination.
For polite request–would you..
Some useful examples :–
•Would you please help me to carry this luggage?
•Would you like to have some fruits in breakfast ?
•Would you write an application for me ?•Would you support me in this election ?
Would for imagination
We express many imaginative conditions that we cannot reverse but with present sense for satisfaction. Like earlier mentioned examples:-
•If I were a police officer, I would finish total crime.
•If I were a rich person, I would help poor children.
•This is different condition compare to present realistic imagination.
•In the present imagination, you are in the position to realize your dreams, but in the past imagination, your are in the present but imagining about past to correct present.
•In the past imagination, you are imagining about your inabilities to recorrect present because you haven’t done better in the past.
•At the same time, you shouldn’t get confused with third conditional sentences in which both conditions express past missed chance.
Missed opportunity With “would have”
In the third conditional sentences, you are imagining about past inabilities, as well as past opportunity to correct.
•As an example, “If you were the member of football world cup team and due to poor practice, you lost an opportunity to win the title, then in such scenario, you would imagine like:-
•If we had practiced persistently, we would have won the title.
•If we had made a little more effort; we would have the world champion.
But, in reality you neither practiced nor won the title. It is only part of expressing regret about past mistakes or missed opportunities.
To express beliefs…
It is used to believe something which isn’t true.
•We assumed that we would not be there on time.
•I thought that it would not rain. Or I thought that it would rain.
•They thought that he would be absent.
This is like believe something, but not imagination. Let’s see the use of ‘would and would have’ in the imaginative sentences.
There are two types of imagination in the conditional sentences. One is realistic, whereas other is unrealistic.
Should modal auxiliary
It is used to express —
In certain situations, should is used to describe “Conditions and expectations” as well.
Should auxiliary — for advice
Most of the times, “should” is used to give advice or recommendations in the public, as well as private life.

To express duties
The one of the most important uses of should modal auxiliary is to prescribe duties but rather polite.

•Definitely, he should be in the team for final match.
•He is so lazy. She should be ready in the early morning.
•They should be there before the train arrives.

Should auxiliary verb to prescribe values
In certain societies, should is actively used to dictate or prescribe values of behaviours.
•We should obey parents.(social values)

These are the basic functions and roles of should modal auxiliary.
