2020版高考英语二轮复习全国版 专题3 完形填空(课件+试卷)

[命题规律] 1．短文以记叙文为主，夹叙夹议文为辅。情节往往不按时间顺序平铺直叙，有插叙或倒叙，有时还夹有描述和评论。 2．以考查实词为主。动词的考查依然是首位，然后是名词、形容词和副词，虚词偶有考查。 3．联系上下文的设空约占80%，结合语篇的设空约占20%，充分体现了“注重基础，难易比例适当，有利于选拔人才”的高考命题思路。 [命题趋势] 1．预计2020年高考依然以记叙文为主，选材上以贴近学生生活的话题为主，包括社会热点、学校生活、人物故事等，以传递正能量、普及社会常识为宗旨。 2．选项布局以考查实词为主，其中动词、名词居多，其次是形容词、副词，对介词等虚词的考查相对较少。 3．从三个层面考查语境理解的能力：对文章整体(文章中心主线和整体结构)的把握和理解；对上下文或句子之间关系的把握和理解；对句子结构和意义的把握和理解。 [完形填空解题四步骤] 第一步：通读全文，理解大意 重视首句信息，把握文章大意，为解题打下良好的基础。 第二步：根据语境，初选答案 解题过程中，应遵循先易后难的原则，先选出那些自己有把握的选项。对少数难题，暂时跳过；或许根据上文信息或后一两句都难以判断的题，在下文中就有暗示或者明显的提示；或许一个在前面不能解答的题，在填出了另一空后会令你豁然开朗。 第三步：研读选项，解决难题 借助已经填完的选项，上下求索、瞻前顾后，集中解决遗留的少数难题。此时我们要从语篇层次进行深入分析。 第四步：复读全文，验证答案 代入选项，重读文章，最终确定答案。 A篇 (2019·全国卷Ⅰ) Every year about 40，000 people attempt to climb Kilimanjaro，the highest mountain in Africa.They 1 with them lots of waste.The 2 might damage the beauty of the place.The glaciers(冰川) are disappearing，changing the 3 of Kilimanjaro.
