9.  Review the structure of the Interrogative sentences. What types of Interrogative sentences do you know?

An interrogative sentence asks a question; it ends with a question mark (?). - Are you leaving Minsk for Moscow tomorrow? Interrogative sentences (questions) have the following characteristics: 1) indirect word order, 2) peculiar interrogative intonation, 3) interrogative pronouns: who, whom, whose, what, which, why, where, how much (many), etc. There are five types of interrogative sentences:

1. General question: questions which can be answered 'yes' or 'no'.

The typical word order:

auxiliary verb +subject group +main verb +object +adverbial modifier

- Is she typing? – Yes, she is. - Has he been working? – No, he hasn’t.

2. Special question: the scheme of all types of special questions except questions about the subject of the sentence:

interrogative word +auxiliary verb +subject group +main verb +object +adverbial modifier

- When did she get the letter? - What colour is your hair?

3. Alternative question: questions which have a structure of general questions but can not be answered 'yes' or 'no'. They need a full answer:

- Are you a lecturer or a student? – I am a student.

4. Disjunctive (or Tail) question: They have two parts: a statement in the first, and tag in the second. Tags generally repeat auxiliaries, like do/did. A positive statement has a negative tag, a negative statement has a positive tag.

- He is not friendly, is he? - You will help me, won't you?

a) it is possible for a positive tag to follow a positive statement, to express interest, or ask for confirmation:

- So, you like working here, do you?

b) tags with will and won't can be used after imperatives:

- Don't drive so fast, will you?

c) let's ... has a tag formed with shall:

- Let's have a drink, shall we?

d) Everyone/Someone/Anyone/No one are used with aren’t they in a tag.

- Someone is knocking at the door, aren't they?

5. Question about the Subject: the word order in questions about the subject of the sentence:

interrogative word +predicate +object +adverbial modifier

- Who plays the piano well? - What is in the box?

Note: Indirect questions. Mind the direct word order in indirect questions:

- I wonder if you can help me. - He inquired whether he could see her.

What do (don’t) they know? They know the history of Economics. 5. A historical topic can be an important tool to create insight, can’t it? 6. Does Economics advance through one technique or the interplay of many techniques? 7. You can’t imagine how well he can solve these problems. 8. I wonder why they are absent today.
