ENGLISH-初三上系列资料（沪教牛津版） Chapter1现在完成时系统用法 考频分析 现在完成时系统用法是中考英语语法的重要模块，考频占语法总量的15%左右，贯穿试卷多个核心题型： 单项选择(1-2题)、完形填空(2-3题)、语法填空(1-2题)、书面表达（核心考察，直接影响句子时态准 确性与上下文逻辑连贯性)。在语境理解类题目中，现在完成时与一般过去时的辨析、for/since时间状语 的搭配及瞬间动词与延续性动词的转换往往是解题关键。 考查内容 中考对现在完成时的考察聚焦三大维度，覆盖基础用法与语境应用： ·基本结构构成：肯定句、否定句、疑问句的句式结构，助动词have/has与过去分词的搭配规则； ·核心用法辨析：表示过去发生并持续到现在的动作或状态，过去发生对现在造成影响的动作，以及与和r、 since、already、yet等时间状语的连用规律； ·语境场景应用：在对话、短文理解中判断动作的完成情况与时间关联性，区分与一般过去时的用法差异。 精讲精练 知识点一：现在完成时的系统用法 ·基本结构 -肯定句：主语+have/has+过去分词 *→例句：I have finished my homework.(第一人称用have) *→例句：She has lived here for5 years.(第三人称单数用has) -否定句：主语+haven't/hasn't+过去分词 *→例句：They haven't seen this movie yet. -疑问句：Have/Has+主语+过去分词？ *例句：Has he arrived at school? ·时间标志词 -表示“已完成”：already(肯定句)、yet(否定句l疑问句)、just *→例句：We have already eaten breakfast. *→例句：Have you read the book yet'? -表示“持续至今”：for+时间段、since+时间点 *→例句：He has studied English for3 years. *例句：They have lived here since2020. -表示“经验经历”：ever、never *→例句：Have you ever been to Beijing? ·核心用法 -用法1：过去发生的动作对现在造成影响（常与already/yet/just连用） *→例句：I have lost my key..Ican't open the door now -用法2：动作从过去持续到现在（常与for/since连用） *→例句：My parents have worked in this factory since2018, -用法3：表示过去到现在的不确定时间内发生的经历（常与ever/never连用） *→例句：She has never visited the Great Wall. ·常见错误提醒 -不可与具体过去时间状语（如yesterday,.last week)连用 have met him yesterday. *I met him yesterday.(用一般过去时) -f和r+时间段前不可加具体时间点 He has lived here for 2020.

A.has died B.died C.has been dead D.was dead -答案：C解析：由时间标志词“for five years'”可知，需用延续性动词；die是短暂性动词，应转换为 be dead,现在完成时结构为has been dead,主语为三单，助动词用has。 考法三：现在完成时综合应用（结构、时间标志词及易错点辨析） ·核心：结合基本结构(have/has+过去分词)、时间标志词(for/since/already/yet等)及易错点（短暂性 动词转换、与一般过去时区别)判断时态并正确使用 ·真题1（单项选择）： -My brotherin this school for 5 years and he loves it very much.
