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。
Have you read Little Women yet Yes, I have./No, I haven’t.
Has Tina read Treasure Island yet Yes, she has. She thinks it’s fantastic.
Have you decided which book to write about yet Yes, I have. I’ve already finished reading it. It was really good.
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 not + 过去分词 + 其他.
I have not seen this film.
现在完成时态（1）
和主语一致
have/has 常可缩略为 -’ve/-’s
Presentation
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.
have not = haven’t; has not = hasn’t
二、过去分词的变化
1. 规则变化（与动词过去式规则一样，此类称作规则
动词）
一般在词尾直接加-ed 以不发音的e结尾的，加 -d 以“辅音字母+ y”结尾的变y为i加-ed 重读闭音节以一个辅音字母结尾的，双写这个辅音字母后加-ed
work→worked slice→sliced study→studied stop→stopped
2. 不规则变化（此类称作不规则动词，有很多）
原形 过去式 过去分词
be was/were been
have had had
choose chose chosen
put put put
run ran run
参看课本P136-137 Irregular Verbs（不规则动词表） 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 of this song
—No. I’ve never heard of it before.
Julia has collected over 100 beautiful hair clips so 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；
past
I had breakfast.
I’m not hungry now.
present
I have already had breakfast.
（早餐过去吃的，现在不饿。）
图示法表示
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.
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。
图示法表示
past
I moved here
in 1990.
I still live here.
present
I 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辨析
yet 常用于否定句或疑问句句末。用于表示某事尚未发生或某情形尚未出现，或用于询问某事是否已经发生。 He hasn’t finished the book yet.
Have you seen him yet
already 常用于肯定句中，用于强调某事已经开始出现；也可用于疑问句中，表示因某事的发生早于预料而感到吃惊。 They have already known each other.
Have you eaten all that food already
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 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
—…
