have/has dne（过去分词）
肯定句：主语 + have/has + 过去分词 + 其他.否定句：主语 + have/has + nt + 过去分词 + 其他.一般疑问句：Have/Has + 主语 + 过去分词 + 其他？特殊疑问句：疑问词 + have/has + 主语 + 过去分词 + 其他？
have/has的用法区别
fr/since用法辨析
since后接具体时间点（如since 2020/since Mnday），表示动作从该点持续至今；fr后接时间段（如fr 3 years/fr a week），强调动作持续的总时长。
since在否定句中表示"自某时间点以来未发生"（如"I haven't seen him since Mnday"）；fr否定句则强调"某状态未持续该时长"（如"He hasn't slept fr days"）。
since仅用于完成时（如现在完成时、过去完成时），例如"She has wrked here since 2018"；fr可用于完成时或一般过去时（如"I lived there fr tw years"）。
询问持续时间用"Hw lng + 完成时"搭配fr（如"Hw lng have yu studied English?"回答"Fr five years"）；询问起点时间用"Since when"（如"Since when has he been ill?"）。
already/yet/just应用
用于肯定句，表示动作已完成（常位于助动词后或句末），如"I have already finished my hmewrk"或"She has read the bk already"。
用于否定句和疑问句，否定句中表示"尚未"（如"He hasn't arrived yet"），疑问句中表"已经"（如"Have yu eaten yet?"）。
强调动作刚完成（通常位于助动词后），如"They have just left the ffice"，隐含"不久之前"的时间概念。
ever/never使用场景
用于询问"是否曾有过经历"，如"Have yu ever been t Japan?"，常与现在完成时搭配。
与hardly/scarcely连用表"几乎从未"（如"I have hardly ever seen such a beautiful sunset"）。
表"从未"，用于否定陈述句（如"She has never tried sushi"），注意never本身已含否定意义，不再与nt连用。
ever可修饰最高级（如"This is the best mvie I've ever seen"），never则用于强调绝对否定（如"I've never met anyne s kind"）。
一般过去时 VS 现在完成时
He ate lunch just nw.
过去吃的，现在饿不饿不知道。
①侧重点在于陈述过去的动作或状态。②动作已结束并与现在没联系。
He has already eaten lunch .
过去吃过了，现在还饱着，不用再吃了。
①强调过去的动作或状态对现在的影响。②在过去某个时间开始并持续到现在的 动作或者状态，有可能还会继续下去。
