Дипломная работа: Modal verbs

E.g. Oughtn’t you to go and have your tiffin?

The of ought to in this case is not very common as this meaning is normally rendered by must : He/You ought to know it (=he is/you are supposed to know it). You ought to be ashamed of yourself.

Shall and should

Historically, shall and should were two forms of the same verb expressing obligation. She was the present tense of the Indicative Mood; should was the Subjunctive Mood. But later they came to express different meanings and in present-day English their use is not parallel – they are treated as two different verbs.

Shall

In modern English the modal meaning of obligation in shall is always combined with the function of an auxiliary verb of the future tense.

Shall is still used to express obligation with the second and third persons, but at present it is not common in this meaning in spoken English. Its use, as a rule, is restricted to formal or even archaic style and mainly found in subordinate clauses, i.e. it is structurally dependent.

E.g. It has been decided that the proposal shall not be opposed.

This book is sold subject to the condition that it shall not , by way of trade, be lent, resold, hired out or otherwise disposed of without the publisher’s consent.

At present, however, this meaning of obligation, somewhat modified, is found with the second and third persons in sentences expressing promise, threat or warning. It is used in affirmative and negative sentences and combined with the simple infinitive.

E.g. You shall have my answer tomorrow.

“You shall stay just where you are!” his mother cried angrily

He shall do as I say.

The meaning of obligation may also be traced in interrogative sentences where shall is used with the first and third persons to ask after the will of the person addressed. In this case it is also followed by the simple infinitive.

E.g. Shall I get you some fresh coffee, Miss Flour?

Who shall answer the telephone, Major?

Sentences of this kind are usually rendered in Russian with the help of the infinitive: Принести Вам ещё кофе? Кому отвечать по телефону? etc.

Should

In modern English the modal verb should is used with reference to the present or future. It remains unchanged in reported speech.

Should has the following meanings:

1) obligation, which in different contexts may acquire additional shades of meaning, such as advisability and desirability ,

E.g. It’s late. You should go to bed.

You shouldn’t miss the opportunity.

Should I talk to him about it?

He said that the status of the Greek minority should be viewed in the light of political balance. (Moscow news)

He said that this was not a temporary problem. Lasting arrangements should be made. (W. Faulkner)

Should in this meaning is found in all kinds of sentences. Like ought to it generally refers an action to the future and followed by the simple infinitive.
