Dog || there. 2-nd IC of the 1-st stage is the group of the predicate (the verb phrase). 1-st IC – the noun phrase. THE PATTERN OF A SENTENCE REPRESENTED BY IC MODEL (IC derivation tree or sentence tree)
The old man saw a black dog there.
IC model establishes syntactical relations between the words in a sentence. It is capable of showing the difference between the structure of sentence. Two examples have different syntactical patterns if analyzed in terms of IC model. We can see difference at the 2-nd stage. 1-st EX: …shot || the man …. 2-nd EX: … shot the man || … However this model has its own limitations. DAVID CRYSTALL: The IC model sometimes fails to provide clear lines where the constituents shall be divided. EX: That nice efficient old-fashioned secretary is here. It is not clear how adj. should be divided, if at all. He also says that the model fails to describe relations for example between active and passive constructions. EX: John is eager to please. John is easy to please. These sentences have identical patterns. The main limitation of the model – it considers the structure of every sentence separately, independently of other sentences.
