Interrogative sentences

§ 8. Interrogative sentences contain questions. Their communicative function consists in asking for information. They belong to the sphere of conversation and only occasionally occur in monological speech.

All varieties of questions may be structurally reduced to two main types, general questions (also called “yes-no” questions) and pronominal questions (otherwise called “special” or “wh” - questions). Both are graphically identified by a question mark. The two main types have a number of structural and communicative modifications.

General questions

§ 9. In general questions the speaker is interested to know whether some event or phenomenon asked about exists or does not exist; accordingly the answer may be positive or negative, thus containing or implying “yes” or “no”.

A general question opens with a verb operator, that is, an auxiliary, modal, or link verb followed by the subject. Such questions are characterized by the rising tone.

Does your sister go figure-skating?

Is that girl a friend of yours?

Can you speak French?

“Yes-no” questions may be incomplete and reduced to two words only: Can you? Does he?

A negative "yes-no" question usually adds some emotional colouring of surprise or disappointment.

Haven’t you posted the letter yet? (Why?)

General questions opening with will/would may be considered as commands and requests according to their communicative role (see § 17).

Owing to their occasional emotional colouring, “ yes-no” questions may function as exclamations (see § 22).

Tag questions

§ 10. A tag question is a short “yes-no” question added to a statement. It consists only of an operator prompted by the predicate verb of the statement and a pronoun prompted by the subject. Generally the tag has a rising tone.

You know French, don’t you? - Yes, a bit.

George is a football fan, isn’t he? - He certainly is.

A tag question is added to a statement for confirmation and therefore is sometimes called aconfirmative question. It corresponds to such Russian tag questions as He так ли? Не правда ли? Ведь так? The speaker expects the listener to share his view of some situation rather than to give him some new information. The most usual patterns of sentences with tag questions are as follows.
