A.something B.new something C.anything new D.new anything 答案：C 解析：疑问句中用anything,形容词修饰不定代词时后置，正确结构为anything new,意为“杂志 里有什么新内容吗”。 考法二：不定代词用法与修饰语位置结合 核心：判断不定代词在具体语境中的正确使用，并掌握形容词修饰不定代词时的后置规则 真题1（语法填空）： Is there_(important)in today's news? 答案：anything important 解析：本句为疑问句，应用不定代词anything:形容词important修饰不定代词时需后置，构成anything important结构，意为“重要的事情”。 真题2（单项选择）： I want to buy-for my mother's birthday. A.something special B.special something C.anything special D.special anything 答案：A 解析：此句为肯定句，表达“想买某样东西”，应用something;形容词special修饰不定代词something 需后置，所以正确答案为something special。 考法三：不定代词与疑问词连用及修饰词位置综合应用 核心：掌握疑问词与不定代词的正确搭配规则，理解形容词修饰不定代词时的后置要求，结合语境 判断不定代词的使用场景。 真题1（单项选择)： Do you know if there is-interesting in the newspaper today? A.something B.anything C.nothing D.everything 答案：B 解析：本句为疑问句，询问“是否有有趣的内容”，应用anything:形容词interesting需后置修饰不 定代词，符合知识点二和知识点三的用法规则。 真题2（语法填空)： Could you tell me_(something/anything)special about your hometown?I want to write a report. 答案：something 解析：虽然句中包含疑问词，但此处为希望得到肯定回答的疑问句，应用something;形容词special 后置修饰something,符合知识点二“something用于希望得到肯定回答的疑问句”及知识点三“疑 问词与不定代词连用”的规则。 4 初中下册教科版（五四制） 【语法专版】A版知识点全解 真题演练 演练一：单项选择试题(10题) 1.My brother wants to readinteresting about space.
