2.3 The analysis of the nuclear sentences based on patterning and expanding the communicative intention of the speaker There are many approaches to classify sentences. B. Ilyish classifies sentences applying two principles. Applying this principle he distinguishes three types of sentences: declarative (She was reading a book then), interrogative (Was she reading a book then?), imperative (Read it!). According to structure Applying this principle he distinguishes two main types of sentences: simple (She was reading a book) and composite (When I came home she was reading a book). Ch. Fries gives an original patterning of types of sentences. All the utterances are divided by him into Communicative and Non-communicative. The Communicative utterances are in their turn divided into 3 groups: utterances regularly eliciting “oral” responses only: Greetings; Calls; Questions; utterances regularly eliciting "action" responses, sometimes accompanied by one of a limited list of oral responses: requests or commands and utterances regularly eliciting conventional signals of attention to continuous discourse statements. L. Barkhudarov compares source (kernel) sentences with their transforms, he distinguishes several types of sentences from their structural view-point. His patterning will represent binary oppositions where the unmarked member is the source kernel sentence and marked one is the transformed sentence. The most important oppositions within the limits of simple sentences are the following two:
1. Imperative (request) and non-imperative sentences.
2. Elliptical and non-elliptical sentences.
The DO is followed by an adjective which indicates result or manner.13
