      Substitution

      替換

       

      A term used in linguistics to refer to the process or result of replacing one item by another at a particular place in a structure. In grammar, the structural context within which this replacement occurs is known as a substitution frame. The set of items which can be used paradigmatically at a given place is known as a substitution class. A word which refers back to a previously occurring element of structure may be called a substitute word. In government-binding theory, substitution is one of the two main types of movement process (the other being adjunction); it involves the moved category replacing an empty category of the same kind in accordance with the structure-preserving constraint. In language teaching, exercises to improve the ability of learners to carry out a process of item replacement are known as substitution drills (or ‘pattern drills’).

       

      語言學用來指一個結構內的某一個位置用一個語項替代另一個的過程或結果。語法中發生這類替換的結構上下文稱作替換框,可填入某一框內的有聚合關系的一組語項稱作替換類。一個回指前面出現過的某一結構成分的詞可稱作替換詞。在管轄與約束理論中,替換是兩大類移位之一(另一類是附接);它指被移語類按照結構保持制約取代一個同類的空語類。在語言教學中,為提高學習者這種替換能力的練習稱作替換練習或“型式”練習。
