现在完成时态
1. 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.(其中，have/has 常可缩略为 -’ve/-’s)
e.g. Linda has read the novel. 琳达读过这本小说。
② 否定句：主语 + have/has not + 过去分词 + 其他. ( 其中，have/has not 常可缩略为 haven’t，hasn’t )
e.g. Linda has not read the novel. 琳达还没有读过这本小说。
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.
e.g. — Have you seen the film
—Yes, I have. / No, I haven’t.
你看过这部电影吗
是的，我看过。/不，我没看过。
2. 过去分词的变化:
(1) 规则变化（与动词过去式规则一样）
① 在词尾直接加“-ed”
e.g. help→helped
② 以不发音的 e 结尾，加 “-d”
e.g. live→lived
③ 以“辅音字母 + y”结尾，变 y 为 i 加“-ed”
e.g. study→studied
④ 重读闭音节以一个辅音字母结尾，双写该辅音字母后加“-ed”
e.g. stop→stopped
(2) 不规则变化
原形 过去式 过去分词
be was/were been
begin began begun
choose chose chosen
put put put
run ran run
… … …
可参考课本P136-137
Irregular Verbs
（不规则动词表）
3. 现在完成时的用法:
(1) 表示过去发生或已经完成的某一动作对现在造成的影响或结果。常与 just、already、before、yet、ever、never、so far等连用。
e.g. — Have you had your lunch yet
— Yes, I have. I’ve just had it.
— 你吃过午饭了吗？
— 是的，我吃过了。我刚刚吃的。
— Have you ever learned the poem
— No. I’ve never learned it before.
— 你学过这首诗吗
— 没有。我以前从没学过。
What have you found so far
迄今为止，你发现了什么？
(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，常与“for + 时间段” 或 “since + 时间点 / 从句” 连用，这时要用延续性动词。
e.g. Linda has taught in this school for twenty years.
琳达在这所学校教了二十年书了。
My brother has been in the army since 2010.
我哥哥从2010年就开始参军了。
【注意】
① for prep. 表示时间的持续，后接时间段，表示一段时间，多与带数词的名词连用，其谓语需用延续性动词。
② since prep. 表示“自从过去某一时间点以来”，后接时间点，强调动作或状态一直延续到现在，一般用现在完成时或现在完成进行时。
如果要对 for 或 since 短语提问，疑问词要用 how long。
e.g. —How long have you lived in Xi’an —For at least 5 years.
— 你在西安住了多久了？ — 至少5年了。
4. 现在完成时中already 与 yet的用法：
(1) 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。
e.g. I have already started knitting baby clothes.
我已经开始织婴儿的衣服了。
Have you finished already That was quick!
你已经做完了？真快呀！
(2) 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。
e.g. I haven’t answered her email yet.
我还没有回复她的电邮。
Have you opened your post yet
