那么这里反复提到的Cohesive Device（衔接手段）究竟是什么呢？专家认为Cohesive Device:（衔接手段）主要指能使信息的逻辑关系更清晰的各种英语字符。逻辑关系主要涉及：并列或递进关系、让步或转折关系、因果关系和举列。具体来看，可分成以下三类：【感觉下面的词汇是不全面的，只少没有分清楚层次 上课要认真听讲啊。】Lexical aspect:（词汇方面）Linking word（连词）：并列或递进关系：and; also; too; or; Besides; furthermore; moreover; likewise; meanwhile等让步或转折关系：but; however; whereas; nonetheless; nevertheless; although; though; otherwise; yet; rather; despite; rather等因果关系：because; so; since; for; so; thus; therefore; thereby; 举例：likeLinking phrase(短语)：Coherence and Cohesion 的7分第二条原文：Uses a range of cohesive devices appropriately although there may be some uner-/over-use6分第二条原文为：Uses cohesive devices effectively, but cohesion within and/or between sentences may be faulty or mechanical;6分第三条提到：May not always use referencing clearly or appropriately与之对应的5分第二条为：Makes inadequate, inaccurate or over-use of cohesive devices5分第三条为：May be repetitive because of lack of referencing and substitution由以上所涉及到的原文可以看出，referencing（指代关系）和substitution（替代）都是cohesive device（衔接手段）的表现，而且是确定分值的重要参考标准。
