Grammar
现在完成时（一）
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
1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 not + 过去分词 + 其他.
I have not 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：No, 主语 +
haven't/hasn't.
—Have you seen the film? —Yes, I have. / No, I haven't.
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worked [wɜːkt]，stopped [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）
2三、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），before（以前），so far（到目前为止）等连用。
— Have you had your breakfast yet?
— Yes, I have. I've just had it.
— Have you ever heard this song?
— No. I've never heard it before.
Julia has collected over 100 beautiful hair clips so far.
图示法表示
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 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“for + 时间段”或“since + 时间点 / 从句”连
用，这时要用延续性动词。
They have worked in this company for 30 years.
He has been in the army since 2016.
（错：He has joined the army since 2016.）
【特别提醒】如果要对for或since短语提问，疑问词用how long。
— How long have you lived in this area?
— For at least 10 years.
图示法表示
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。
3I have lived here for 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
1.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 done my homework.（不能用last night等）
I've been to Paris before.（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 homework last night.
When did you go to 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 you been to Japan?
— Yes, I have. I went there last year.
— Who did you go with?
— …
