1、概要写作的评分标准之一是“上下文的连贯性”，要求你有效地运用一定的衔接手段，使所写的句子连贯、流畅。在概要写作时，我们可以借用三种衔接手段使上下文连贯，即词汇衔接、逻辑衔接和语法衔接。微技能六运用衔接手段微技能六运用衔接手段词汇衔接指运用原词、近义词或反义词、上下义词等的复现和同一语义场词汇的共现等方法。如：job和doctor,teacher,translator为上义词与下义词的关系；learn,education和knowledge等为同一语义场词汇。逻辑衔接 指利用表逻辑关系的过渡词来衔接上下句的方法，如besides,however等。语法衔接常见的有替代和省略。替代是指用代词替代前
2、面相应的名词或名词性短语和句子，用助动词替代前面的动词和动词短语。省略是指为了表达简洁，在语境清楚的条件下，省去某个词句。常见的省略有蒙上省略，即省去上文已提到的词句；探下省略，即省去下文将提到的词句。1因果关系(1)显性因：because,becauseof,for,as,since,inthat,onaccountof,nowthat显性果：so,sothat,therefore,asaresult,thus,consequently,accordingly(2)隐性因果：导致(因果)：cause,reason,leadto,giveriseto,resultin,stimulate,fu
