含现在完成时的句子如何构成一般疑问句？
将助动词have / has放在主语之前。
一、现在完成时的基本结构现在完成时由“助动词have/has + 过去分词”构成，其基本句式结构为：① 肯定句：主语 + have/has + 过去分词 + 其他.I have seen this film.② 否定句：主语 + have/has nt + 过去分词 + 其他.I have nt seen this film.③ 一般疑问句：Have/Has + 主语 + 过去分词 + 其他?肯定回答：Yes, 主语 + have/has. 否定回答：N, 主语 + haven't/hasn't.—Have yu seen the film? —Yes, I have. / N, I haven't.
have nt = haven't; has nt = hasn't
have/has常可缩略为 -'ve/-'s
二、过去分词的构成1. 规则变化（与动词过去式规则一样，此类称作规则动词）
-ed的读音规则：① 在元音或浊辅音后读[d]，如tried [traɪd]，lived [lɪvd]。② 在清辅音后读[t]，如wrked [wɜːkt]，stpped [stɒpt]。③ 在[t][d]后读[ɪd]，如mended [mendɪd]，wanted [wɒntɪd]。
2. 不规则变化（此类称作不规则动词，有很多）
三、现在完成时的用法1. 表示过去发生或已经完成的动作对现在造成的影响或结果。常和 just（刚刚），already（已经），yet（还，仍然），ever（曾经），never（从未），befre（以前），s far（到目前为止）等连用。— Have yu had yur breakfast yet? — Yes, I have. I've just had it. — Have yu ever heard this sng?— N. I've never heard it befre.Julia has cllected ver 100 beautiful hair clips s far.
现在完成时用法1：表示过去发生或已经完成的动作对现在造成的影响或结果。
I had breakfast.
I'm nt hungry nw.
I have already had breakfast.
2. 现在完成时还可以表示过去某一时间开始并一直持续到现在的动作或状态，常与“fr + 时间段”或“since + 时间点 / 从句”连用，这时要用延续性动词。They have wrked in this cmpany fr 30 years.He has been in the army since 2016.（错：He has jined the army since 2016.）【特别提醒】如果要对fr或since短语提问，疑问词用hw lng。 — Hw lng have yu lived in this area? — Fr at least 10 years.
现在完成时用法2：表示过去某一时间开始并一直持续到现在的动作或状态。
I mved here in 1990.
I still live here.
I have lived here fr 30 years.(30年来一直生活在这里。）
四、already与yet在现在完成时中的用法解析
五、现在完成时 VS 一般过去时现在完成时表示过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况，因此不能和表示过去的时间状语连用。I have already dne my hmewrk.（不能用last night等）I've been t Paris befre.（不能用last year等） 2.一般过去时只表示过去的动作和状态，与现在无关。可以和表示过去的时间状语连用。I did my hmewrk last night.When did yu g t Paris? （when一定不要和现在完成时连用）
3. 日常对话中通常两种时态配合使用，开始提到一件事做没做或发生过时用现在完成时，说起这件事具体情形时用一般过去时。— Have yu been t Japan?— Yes, I have. I went there last year.— Wh did yu g with?— …
