Chapter 8 Meaning and Context 意义和语境
Context in its traditional sense refers to the lexical items that precede or follow a given word. Modern linguists have broadened its scope to include both linguistic and extra-linguistic contexts.
Two types of context
Linguistic context：It refers to the words,clauses,sentences in which a word appears. It may cover a paragraph,a whole chapter and even the entire book.
1) Lexical context：It refers to the word that occurs together with the word in question.
2) Grammatical context：It refers the situation when the meaning of a word may be influenced by the structure in which it occurs.
Extra-linguistic context：In a broad sense,it includes the physical situaion as well.it embraces the people, time, place, and even the whole cultural background.
