用英文给下列单词名词解释

Cohesive Ties
The local coherence in a text that is established by using words that link sentences together.
Focuses on the relationship between cohesion and comprehension.
Cohesion is the type of language redundancy that links one sentence or phrase with another.

Lexical cohesion
Lexical cohesion is basically created by repetition (reiteration) of the same lexeme, or general nouns (super-ordinates, for example - public transport), or other lexemes sharing the majority of semantic features (also called hyponyms): The bus ... - the subway... - the tram....
Lexical cohesion can also form relational patterns in text in a way that links sentences to create an overall feature of coherence with the audience, sometimes overlapping with other cohesion features. The understanding of how the content of sentences is linked helps to identify the central information in texts by means of a possible summary. This allows judgements on what the text is about.
