1、语法填空考点知识梳理题型解读一篇200字左右的短文中留出10个空白,要求学生根据上下文情境,在空白处填入适当的内容或所提供单词的正确形式。语法填空题考查学生在篇章层面上理解并应用语法知识的能力。该题型要求学生必须具备较好的语法分析能力,而不只是语法辨析能力,其着重点是学生的语法基础知识和应用能力。学生必须既考虑句子结构的语法性,又顾及上下文的连贯。命题特点考查内容:有给提示词和不给提示词两种形式。给出提示词的考查点包括:词形的转换,如名词与动词的转换、形容词与副词的转换、名词与形容词的转换、动词与形容词的转换;形容词或副词比较级与最高级的变化;名词单复数的变化;动词的时态、语态以及词形的变化。
2、不给出提示词的考查点包括:根据上下文的语境填入冠词、代词、连词、介词、副词、情态动词、助动词、特殊疑问词、关系词等。特点:给出提示词的空较多(47个) ;考查词形变化的空偏多,并且未给出提示词的空有填实词的情况;每空所填不超过3个单词。文章的首句和末句一般不留空格, 至少第一句话是完整的, 这样学生可以大体了解文章内容,把握作者的写作风格。文章中的人名、地名等专有名词,以及日期、数字等是不作为考点的,因为这类信息如果只在文章中出现一次,学生是无法根据语言线索或其他线索填出的。语法填空不以学生常犯的语法错误作为干扰项,因为该题型主要测试学生的语篇应用能力,而将“偏”“难”“怪” 的语法现象编成干
3、扰项与文章理解没有直接关系,偏离了测试目标。【语法特点】实词以考查动词、代词、形容词、副词为主,其中动词又是重中之重;虚词以考查介词、冠词、连词为主。而句法方面主要考查复合句的引导词,如定语从句、名词性从句、状语从句。练习5For the first time in history, earthlings can hear what a black hole sounds like: a low-pitched groaning, as if a very creaky heavy door was being opened again and again.NASA 1 (release) a
