1. Cohesion is achieved either grammatically or lexically. Grammatical cohesion is reference, substitution, and ellipsis, as they involve closed systems: simple options of presence or absence, and systems such as those of person, number, proximity and degree of comparison.
Lexical cohesion is achieved generally by using content words; it involves a kind of choice that is open-ended, the selection of a lexical item that is in some way related to one that appears previously in the text.
Conjunction is on the borderline of the grammatical and the lexical cohesive device; the set of conjunctive elements can probably be interpreted grammatically in terms of systems, but such an interpretation would be fairly complex and some conjunctive expressions involve lexical selection as well.
2. A text is regarded as the linguistics forms in a stretch of language, and the interpretations of them do not vary with context. It seems that their meaning were constant for all users.
Discourse is a stretch of language in use, taking on meaning in context for its users, and perceived by them as purposeful, meaningful, and connected.
Discourse analysis is the study of the structure of naturally occurring spoken language; while text analysis is on the structure of written language. But the distinction is not clear-out.
