Language pints
知识点1:现在完成时表“持续”核心概念核心含义:表示从过去开始，持续到现在的动作/状态强调重点:动作的持续性，常与since/fr搭配使用时间逻辑:过去的某个时间开始，一直延续到当下本单元贴合:描述志愿者工作、持续的行为状态等场景关键:不强调动作结束，只关注“从过去到现在”的持续
知识点2:基本结构(肯/否句)1.肯定句:主语+ have/has+动词过去分词(v.-ed)单复数规则:I/we/yu/they→have; he/she/it→has例句:She has wrked as a vlunteer fr tw years.2.否定句: 主语+ have/has + nt +动词过去分词缩写:haven't/ hasn't例句:They haven't lived here since 2020.
知识点3:特殊疑问句式(重点)核心疑问词:Hw lng(多久，询问持续时间)句式:Hw lng+ have/has +主语+过去分词?回答方式:直接用since/fr引导的短语作答例句:-Hw lng have yu been here? -Fr three mnths.易错点:不可用When提问持续时间，只能用Hw lng
知识点4:since vs fr核心对比
since 用法详解1.后接具体过去时间点:last week, 2022, yesterday mrning例句:I have been a student here since last September.2.后接一般过去时的完整句子:主+谓(过去式)+其他例句:They have lived here since they gt married.3.位置:可置于句首或句中，句首时加逗号4.关键: since后不能接时间段，只能接“点”或“句子”
fr用法详解1.后接纯时间段:three days, five mnths, half a year例句:He has taught in this schl fr eight years.2.可接模糊时间段:a lng time, a while, several years例句:We have waited fr a lng time.3.位置:只能置于句中，不可句首4.关键: fr后不能接时间点，只能接持续的时间长度
知识点5:延续性动词与短暂性动词(核心难点)1.现在完成时表“持续”时，必须用延续性动词2.延续性动词:表示动作可持续、可延续(如live, wrk, knw )3.短暂性动词:表示动作瞬间完成、不可持续(如jin, leave, start)4.易错点: 短暂性动词不能与since/fr连用，需转换为延续性动词5.核心原则:表“持续多久”，动作必须能“延续”
常见短暂性→延续性动词转换
