通用版2020高考英语二轮复习专题4语法填空4.1解题技法总论课件新人教版.ppt

1、专题四 语法填空第一部分 解题技法总论【考情透析】根据近三年的高考试题可以看出,高考语法填空充分体现了“实词考查为主、虚词考查为辅”的命题原则。命题形式分为提示类填空和自由类填空。1.提示类填空全国卷中,提示类填空为7个实词。主要考查动词的时态、语态、主谓一致、非谓语动词、名词的复数形式、形容词和副词的比较级、代词的格及同一词根的不同词性的转化。2.自由类填空全国卷中,自由类填空为3个虚词。主要考查代词、介词、冠词、连词、时间及地点副词等。【策略点睛】1.利用体裁特点解题快速通读整篇文章,了解其体裁特征,理清其逻辑关系,初步摸清文章的主题、大意、时态、语态等,给分析句子和填空提供可靠的逻辑推理

2、依据。2.利用句法分析解题语法填空主要是从语法角度入手,对句子结构进行分析。简单句要分析其成分是否完整;每种成分由什么样的词性来充当;复合句要弄清从句的作用以及主从句之间的逻辑关系;特殊句式要分析是否符合其固定的格式。3.利用习惯搭配解题英语中有许多固定的词组、短语和句型,在通读全文的基础上,认真分析句子结构,准确辨识句子中的这些固定搭配,利用平时的积累,基本上凭语感就可以解题。4.利用语篇标志解题语篇是一系列连续的语段或句子所构成的语言整体,其中各成分之间,在形式上是衔接的,在语义上是连贯的。起到语篇之间联系作用的词语就是语篇标志。如:firstly,secondly,next等表次序和列举

3、;again,moreover,what is more等表递进;similarly,equally,as with等表相似;so,altogether,thus,in short等表总结等。利用这些语篇标志有助于准确把握句子之间的逻辑关系,弄清文章的来龙去脉。一、题型剖析,有的放矢拿高分二、考场思维,实战得高分(2019全国卷)阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland.Whi
