当空格前后都是句子(一个主谓关系算一个句子)，且这两个句子之间没有关联词时，填关联词；若并列的两个或几个单词或短语之间没有连词，填表示联合、选择、转折等意义的连词(and/but/so/or)；从属句间常依据句子的属性是名词性从句、形容词性从句还是副词性从句来确定其关联词。
具体解题技巧如下：第一步：分析结构，若两个句子(有两个主谓结构)之间，没有句号或分号，也没有连接词，空格必填连接词(此处的连接词包括并列连词，如：and, but, or, while, so, for等；引导状语从句的从属连词；引导定语从句的关系代词和关系副词；引导名词性从句的连接代词、连接副词和连词that, if, whether)。
第二步：根据两句之间的意义和逻辑关系，或根据句式结构来确定是并列结构还是某种主从复合句。
第三步：若是主从复合句，要根据从句的特点，结合连词的意义和作用，确定填具体的某个连接词。

英语二轮复习语法填空(三)(四)答案
国教中心2019--2020学年度高三下期英语二轮复习专题学案语法填空（三）答案考向一有提示词一、提示词为动词动词在7个提示词中所占的比重最大，一般4个；以考查动词的时态和语态、非谓语动词以及词形转换为主。
1．谓语和非谓语的判断根据英语的句法结构，如果一个句子中要出现多个动作，构成的句式有以下三种：[典例1]Modern methods 63.of/for tracking polar bear populations have been employed only since the mid1980s，and are expensive 64 (perform) consistently over a large area.(2019·全国Ⅰ) [to perform空格前出现了谓语动词are，且后边没有连词出现，故此处用非谓语动词；本句含有“主语＋be＋adj.＋不定式”结构，通常用不定式的主动形式表被动意义。
故答案为to perform。
][典例2]I love coming here and seeing my family and all the friends I 66 (make) over the years.(2019·全国Ⅱ)[have made由第二个连词and可知，此处为两个并列句。
故空处应填谓语动词，根据时间状语over the years可知，空处应用现在完成时，故答案为have made。
]2．谓语动词的时态和语态判断所填空处为谓语动词之后，根据以下三个步骤做题：[典例3]In recent years some Inuit people in Nunavut 65 (report) increases in bear sightings around human settlements，leading to a 66.belief that populations are increasing.(2019·全国Ⅰ) [have reported 根据上下文语境，尤其是时间状语In recent years可知，主句用现在完成时态，故填have reported。
