INTRODUCTION
In English grammar, modal verbs are a special group of verbs that help to give a special meaning to a full verb and help to express the accurate mood of the information hidden within the utterance.

Thanks to them the full verb indicate the right type of modality that is: ability, duty, obligation, possibility, suggestion, feeling, opinion, advisability or arrangement and the speaker is able to express a large scale of various smaller or bigger changes in temper as well as differentiate one's state of mind.
The modal verb should is one of modal verbs that help to express large scale of emotions of the sender. What is fascinating, there is no such a modal verb that would have such a large scale of possible uses and would be able to help to create so many various couplings in terms of a morfological service on a syntactical level.
In some cases the modal verb should is still used just as the past form of shall. Or is replaced by modal verb ought to, or by would or could, or can be used as a marker of hypothetical or putative meaning. It is also used to express personal reactions to events, in questions expressing irritation or inability to understand, or with adjectives to express the idea that something must be done or is important. In negative form the modal verb ought to is not common and is often replaced by shouldn't or should not. In order to find out all these special cases of possible use of modal verbs shall and should and of their negative forms there will be an interesting survey into the grammatical world with its specific rules that nowadays retreat or collide with colloquial use in standard English, since the historical retrospective till the modern, often colloquial means of language of modern English.
