4。2 Classifications of lexical repetition文献综述

 According to the definition of the lexical repetition, we know that Karoly Krisztina makes the principal categories of repetition fall into two groups: lexical relations and text-bound relations。 Lexical repetition as a cohesive relation may be broken down into two further categories, same unit repetition and different unit repetition。 Within the same category of same unit repetition two subclasses are distinguished, i。e。 simple repetition and derived repetition, as defined above。

As argued earlier, in the category of different unit repetition, the lexical unit is not repeated; different unit repetition involves the total or partial repetition of the information content of the lexical unit, and thus included a wider variety of semantic relations, namely synonym, opposites, hyponymy, meronymy, and text-bound instantial relations。 Out of the five categories only two-synonym and the group of opposites----retain the simple and derived distinction observed in same unit repetition。 The reason for retaining this distinction only for synonym and the group of opposites is that hyponymy, meronymy, and the instantial relations are already relatively looser semantic links, and so the inclusion of their derivational variants in the analysis would broaden the scope of the investigation。
