      1)話題

      2(Topic Sentence)話題句

       

      (1) A term used in semantics and grammar as part of an alternative binary characterization of sentence structure to that traditionally found in the subject / predicate distinction; the opposite term is comment. The topic of a sentence is the entity (person, thing, etc.) about which something is said, whereas the further statement made about this entity is the comment. The usefulness of the distinction is that it enables general statements to be made about the relationships between sentences which the subject / predicate distinction (along with other contrasts of this type) obscures. The topic often coincides with the subject of a sentence, but it need not , and, even when it is a subject, it need not come first in a sentence. It is sometimes referred to as the ‘psychological subject’. Topicalization takes place when a constituent is moved to the front of a sentence, so that it functions as topic.

      (2) The phrase topic sentence is used in traditional studies of the structure of paragraphs, to refer to the sentence which introduces the paragraph’s theme.

       

      (1)語義學和語法對句子結構的二分描寫用話題/評述來取代傳統的主語/謂語二分法。句子的話題是對其作出說明的那個實體(人、物等),而對這個實體的進一步說明則是評述。這種區分的好處是能對句子之間的一些關系作出概括的說明,而這些關系被主語/謂語的區分(以及其他類似的對立)所掩蓋。話題常與句子的主語重合,但不總是重合,而且話題即便是主語也不一定位于句首。話題有時稱作“心理主語”。話題化是指一個組構成分移到句首位置充當話題。

      (2)這個術語在對段落結構的傳統研究中指引入段落主題的那個句子。
