18、近，上下文的衔接关系越紧密。二）代词指代法解题英语表达中代词出现的频率极高，代词的作用无非是指代前面提及的名词或起名词作用的短语、分句或句子，巧妙利用这样的指代关系和根据代词的单复数差异可以准确而快速地解题。代词指代一定要注意两种情况：一是选项中的代词要特别关注，二是空格后面的句子中的代词要特别关注。02 逻辑关系题一篇文章往往是一个有机的整体，各部分之间存在着一定的联系。从逻辑意义上来看，句子与句子之间常常有并列、顺承、递进、转折、总分、解释、因果等关系，有时甚至包含多种这样的关系。因此，理解阅读材料时一定要把握文章脉络，弄清其中的逻辑关系。如果文中或选项中出现了逻辑关系词，考生就可以利用逻

19、辑关系词来进行推断；如果文中或选项中未出现逻辑关系词，这就需要考生全面理解文章大意，根据上下文语境弄清文章内在的逻辑关系，做出正确的判断。逻辑连接是组织文章最主要的方式，语义逻辑构成了语篇的框架。对常用的逻辑关系了然于心，并在阅读时能有效地找出其连接的对应点，是学生解答“七选五”的关键。“七选五”中常见的逻辑连接可以归类为六种：（1） 并列选择，指选项与前句或后句在结构或内容上一致；（2） 顺承递进，指后句对前句进行补充说明或语义上的延伸；（3） 转折对比，指选项与前句或后句语义相反或相对，后句往往是对前句的修正，表达作者的真正意图；（4） 因果目的，指选项与前后句构成因果关系；（5） 概括阐

20、释，指前句对后句或后句对前句进行归纳概括，若前句归纳，后句即是对前句的具体阐释，使得概念更加清晰易懂；若后句概括，即后句是对前句所阐释的内容进行意义整合；（6） 例证关系，指后句是前句的具体实例。考向01-线索词汇题1.【2022全国甲卷节选】Chopstick Rules The way you handle chopsticks is important to avoid annoying your companions.When you put them down between bites, always put them down together so they are paral
