连接词 Connectives
Connectives play an important role in the creation of cohesive links between ideas and clauses and provide clues about text organization (Cain & Nash, 2011; Crismore, Markkanen, & Steffensen, 1993; Longo, 1994; Sanders & Noordman, 2000; van de Kopple, 1985). Coh-Metrix provides an incidence score (occurrence per 1000 words) for all connectives (CNCAll) as well as different types of connectives. Indices are provided on five general classes of connectives (Halliday & Hasan, 1976; Louwerse, 2001): causal (CNCCaus; because, so), logical (CNCLogic; and, or), adversative/contrastive (CNCADC; although, whereas), temporal (CNCTemp, CNCTempx; first, until), and additive (CNCAdd; and, moreover). In addition, there is a distinction between positive connectives (CNCPos; also, moreover) and negative connectives (CNCNeg; however, but).
连接词在建立观点和分句之间的衔接上发挥着重要作用，并为文本组织提供线索（Cain & Nash, 2011; Crismore, Markkanen, & Steffensen, 1993; Longo, 1994; Sanders & Noordman, 2000; van de Kopple, 1985）。Coh-Metrix 为所有连接词（CNCAll）以及不同类型的连接词提供了发生率得分（每 1000 个词的发生率）。提供了五类一般连接词的指数（Halliday & Hasan, 1976; Louwerse, 2001）：因果（CNCCaus; because, so）、逻辑（CNCLogic; and, or）、对照/对比（CNCADC; although, whereas）、时间（CNCTemp, CNCTempx; first, until）和附加（CNCAdd; and, moreover）。此外，还有正连接词（CNCPos；也，此外）和负连接词（CNCNeg；然而，但是）之分。
