1、2013高考英语二轮完形填空与阅读填空（8）（答案）一、 考情分析 说明文是对事物的特征、本质、性能、状态或事物的发生、发展、结果、用途、原理等进行介绍、解释和说明的一种文体。天文地理、人情世故、客观事物、主观意识等宇宙间的一切都可以通过说明文加以阐述说明。说明文的主要目的是帮助读者认清事物，明白事理，故其语言通常较为浅显、通俗，比较易于读者理解。说明文的内容也很客观、真实，它的用词总是贴近事物的本来面目，没有华丽的辞藻和夸张的写作手法，一般也不加以描述和议论。说明文的内容比较直白，脉络清晰，有没有很多的感情因素掺入，所以就不会有过多情感词汇，在理解上自然不会有走不出去的迷宫。说明文的层次清晰
2、，整体性强。所以，递进性词汇和名词的设题较多。只有把握这些关键，做完形填空题时才能得心应手，游刃有余。二、 要点突破重要语法知识掌握牢、理解长句和难句的句子结构 对于语法结构的考查主要集中在定语从句（连接词、限制性定语从句与非限制性定语从句的区别、定语从句与其它主从复合句的区别）、状语从句。非谓语动词（不定式、现在分词、过去分词、动名词）、时态和语态、特殊句型（省略句、倒装句等）以及一些词类之间的搭配知识（如名词需要形容词、名词、冠词、非谓语动词、词组及定语从句修饰，动词需要副词修饰等语法项目上。此类题除了要求考生具备系统准确的语法知识之外，还要求考生注意上下文之间的逻辑关系，这样才能提高答题
3、的准确率。这样层次的考点主要涉及句子间的关系代词、连词等。 英语中常见得长难句：英语中常见的长难句有如下几个特点：句子信息量大，结构复杂，或附加成分多（几种从句同时出现），分隔现象普遍（主谓分隔、同位语分隔、定语分隔等），有时还会出现省略现象。1、 夹杂有过去分词短语、现在分词短语、动名词或定义从句。2、 夹杂有虚拟语气、宾语从句或定语从句。3、 夹杂有定语从句、时间状语从句或条件从句。4、 夹杂有让步状语从句、现在分词短语或过去分词短语5、 夹杂有过去分词短语、宾语从句，并且主语、谓语出现分隔现象。【例】(2010年高考全国卷)The nurse had him take a36(seat)
