2018高考英语语法填空：名词提示的解题技巧和跟踪训练题（含解析）
高考英语语法填空****** |有提示词的解题技巧
【括号内提供的是名词】
①括号内提供的如果是名词，尤其是单数名词，就应该考虑空格处是否需要填冠
词（a, an，the）、物主代词（my，your，his等）、指示代词（this，that等）、不定代词（few，little，many，much，all，each, every，both，neither，other等）、名词所有格或形容词等对名词进行修饰。

②相反，如果给出的名词是在冠词、物主代词、指示代词、不定代词、名词所有格或形容词之后，则应考虑填名词。

但不要忘记，要考虑名词是否变复数，是否用所有格形式等。

如：
One of my father 'avorite ________ （say）as I was growing up was ! ” “ Try it
答案say ings
这道题主要考查考生在特定语境中正确使用名词复数的能力。

考查考生是否知道
“one o f名词的复数形式”在句子中作主语，谓语动词用单数形式。

本句中as引导时间状语从句，表达的功能是时空”概念。

该从句没有直接放在主
句之后，而是进行了插入，放在了主句的主语之后，进行强调。

完整的主句是：
One of my father ' s favorite __________ （say）was .从该句■的主系表结构中可以
看出，one of my father ' s favorite 在句子中作＞主语。

say要做两次转换：首先要转换成为名词；再将名词转为相应的复数形式。

say的
名词是saying,其复数形式是sayings考生如果写对了saying只是做到了词形正确，同时还要保持单词的正确。

所以正确答案是say in gs
③当括号内提供的是名词时，还可能考查形容词。

如:
There, my voice sounds really ________(wonder) because there ' s a slight echo to it. 答案won derful括号内提供的是名词，但此空作系动词sou nds的表语，所以要
使用形容词形式。

有时也可能考查副词、动词等。

如：
A certa in man pla nted a rose and watered it ______ (faith)a nd before it blossomed
he exam ined it.
答案faithfully 括号内提供的是名词，但此空在句中作状语，修饰动词
watered,所以要变成副词。

注意：先将名词faith变成形容词faithful，然后再变成
副词faithfully。
