fail. He suggests we should help him. If it should rain tomorrow we shall stay home.

c) In the first person it may occur as part of the Conditional Mood though in Modern English such uses are regarded as either formal or old-fashioned. For example: / should be surprised if he came.

2. As a modal, should is used in its full form with all persons and performs two functions.

a) It is used to express mild obligation in the form of advice or recommendation: If you see anything unusual you should call the police. He shouldn't be so impatient with the child.

6.15. Modals

Modal verbs are used to express the speaker's attitu­de towards the action or state denoted by the infinitive they are grammatically associated with, that is they show actions denoted by infinitives as obligatory, necessary, advisable, desirable, possible, impossible, uncertain, etc. They are: must, can (could), may (might), ought, shall, will, should, would, be, have, need, dare.

Modals are called defective verbs since most of them lack the non-finite forms and cannot be used in the analytical patterns such as perfect, continuous, passive as well as future tense forms. The exceptions are: be, have, need and dare. Besides, modals do not take the -(e)s suf­fix in the first person singular. Such verbs as be and have are characterized by the special forms of their own: The train is to arrive in an hour. The boy has to go to school.

Modals normally take infinitives without to with the exception of ought, be, have and sometimes dare and need.

Modals do not require any auxiliary to form ques­tions and negative sentences except for the verb have. Do your children have to wear a uniform at school? Does she have to get up early tomorrow?

According to the meaning modals can be classified into several groups: 1) verbs expressing obligation, ne­cessity — must, have to, be to, shall, should, ought to; 2) verbs denoting supposition, possibility, certainty/uncer­tainty must, may(might), can(could), should, ought to, will, 3) verbs expressing ability — can(could), 4) verbs expressing permission, requests, offers, invitations — may/

might, will/would, can/could, 5) verbs denoting willing­ness will, would.
