Today is mainly about Deixis.

First the teacher give us a review of what we have learnt before.

顺应论 adaptation

the basic idea  about adaptation is that  language use is a process of making choices.
the process happens between the linguitics perspective and context. so it give great emphasis to context, language structure, stradgeties of making choices, and the 处理的特征和机制。

Deixis

Deixis is the function that language and context are grammarlized and encoded .Foe example, the function of pronoun, tense, utterance, spatial and temporal words.

How does language inference the context?

deictic center

For example, Egocen'tricity, Deictic projection.

Egocentricity 自我中心论

it take the time, space ,social status ,discourse context of the speaker as the center.

For example, the joke about a professor. He send a note written "bring your slippers with the boy" to his wife rather than a note "bring my slippers with the boy". this is because he take the addressee as the egocenter. Thus, the joke is created.

Deictic projection指示投射（shift  from the producer to sbelse)

for example, there are two sentences namely

I'll come to your house.(YOU as the center)  I'll go to your house.(I as the center).

marked deictic center(there is a shift). it can happen both in the linguitics aspect and context.

Marked Deictics can be used in the literature to analyze the point of view shift.
