现在完成时——动词过去分词变化规则
以 “辅音字母 + y” 结尾变 y 为 i，再加 -ed
study→studied；carry→carried；worry→worried
一般情况直接加 -ed
work→worked；play→played；clean→cleaned
清辅音后读 /t/； 浊辅音 / 元音后读 /d/；/t//d/ 后读 / d/
以不发音的 e 结尾直接加 -d
live→lived；use→used；dance→danced 统一读 /d/
“辅 + 元 + 辅” 结尾且重读在末尾 双写末尾辅音字母，再加 -ed stop→stopped；plan→planned；shop→shopped清辅音双写后读 /t/；浊辅音双写后读 /d/
规则变化的核心：在动词原形基础上，通过加 -ed /-d/-ied 或双写尾字母加 -ed 构成
Presentation
现在完成时——动词过去分词变化规则
三态同形:原形 = 过去式 = 过去分词
口诀：“放（put）下让（let），读（read）书切（cut），打（hit）击伤（hurt），花费（cost）住
二态同形:原形≠(过去式 = 过去分词）
sleep slept slept 睡
buy bought bought 买
bring brought brought 带来
think thought thought 认为
teach taught taught 教
say said said 说
tell told told 告诉
三态全不同:原形≠过去式≠过去分词

现在完成时——句式结构
Presentation
现在完成时——延续性动词&非延续性动词
1.I ____ __ (buy) this book for two weeks.
2.My uncle ___ ___ (leave) Shanghai since
last Friday.
3.The door __ ____ (close) for an hour.
4.She _____ _ (know) me for 5 years.
5.The movie ____ __ (begin) for 10 minutes.
6.We ___ ___ (live) here since 2018.
7.His grandpa _____ _ (die) for 3 years.
8.I __ ____ (borrow) the pen from Tom
for two days.
has bought
has left
has closed
has known
has begun
has lived
has died
has borrowed
为什么同样是现在完成时，接for/since（表持续的时间状语），有的动词能直接填，有的却完全错误？
know/live→ 延续性动词
特点：动作 / 状态能持续一段时间，可直接和 for/since 连用，动作从过去持续到现在。
know认识→ 能持续 5 年；live居住→ 能持续到 2018 年至今。
故可以直接填写它的过去分词形式。
为生么其它的不可以，它们又该如何填写？
Presentation
现在完成时——延续性动词&非延续性动词
buy/leave/close 等→ 非延续性动词
特点：动作瞬间发生、瞬间结束，没有持续过程，绝对不能和 for/since 连用，一用就错！
buy（买）→ 付钱拿到书的瞬间就完成了，不可能 买持续两周；die去世→ 瞬间发生，不可能 去世持续 3 年。
现在完成时接 for/since表持续→ 必须用延续性动词。
非延续性动词 → 转换为对应的延续性动词 / 短语，再用 have/has been+...
1.I ____ __ (buy) this book for two weeks.
2.My uncle ___ ___ (leave) Shanghai since last Friday.
3.The door __ ____ (close) for an hour.
4.She _____ _ (know) me for 5 years.
5.The movie ____ __ (begin) for 10 minutes.
6.We ___ ___ (live) here since 2018.
7.His grandpa _____ _ (die) for 3 years.
8.I __ ____ (borrow) the pen from Tom for two days.
Presentation
现在完成时——延续性动词&非延续性动词
has bought
has left
has closed
has known
has lived
has died
has borrowed
has begun
has bought → has had（buy→have 拥有，能持续）
has left → has been away from（leave→be away from 离开的，能持续）
has closed → has been closed（close→be closed 关着的，表状态可持续）
has begun → has been on（begin→be on 进行着，能持续）
has died → has been dead（die→be dead 去世的，表状态可持续）
has borrowed → has kept（borrow→keep 保留，能持续）
has had
has been away from
has been closed
has been on
has been dead
has kept
Presentation
现在完成时——一般过去时与现在完成时的区别
I ______ (visit) my grandparentslast weekend.
(Past Simple)
She ______ (lose) her keyyesterday.
(Past Simple)
I ______ (visit) my grandparents three timesthis month.
(Present Perfect)
She ______ (lose) her key. She can't get in now.
(Present Perfect)
visited
have visited
lost
has lost
两者均表过去发生的动作，核心差异在于：是否强调 过去动作与现在的关联，以及时间状语的搭配，
一般过去时：只谈过去，动作是 “过去的孤立事件”，和现在毫无关联，相当于 “给过去的动作画句号”。
现在完成时：谈过去，落脚现在，动作要么 “对现在有影响 / 结果”，要么 “持续到现在 / 反复发生”，相当于 “给过去的动作画省略号，连到现在”。
