现在完成时态 （ 黄艳海）
Talk about:
1.Have you finished your homework
2.Has she cleaned the classroom yet
3.Have you had your breakfast yet
4.Lilei has lost his schoolbag already
How long have you been here
写出下列动词的过去分词
※ work （ ） ※arrive（ ）
start （ ） live （ )
※ study （ ） ※ stop （ ）
carry （ ） plan （ ）
※ Have （ ）
keep （ ）
现在完成时的构成：
由“have / has +动词的过去分词”，
have 和has常缩为’ve ，’s ，否定缩写
have not = haven’t ，has not = hasn’t
worked
started
arrived
lived
studied
carried
stopped
planned
had
kept
二.现在完成时态的用法
（一）表示过去已发生或已完成的动作对现在造成的影响或结果.
如: 1. They have cleaned the classroom already. (The classroom is clean now.)
2. I have had my breakfast.( I am full now.)
3. My father has not come back yet.(He is not here now.)
注：常与already /yet /just ever never等副词连用。(注意：already用于肯定句中，yet用于否定句或疑问句中）
(二）表示从过去，持续到现在的动作或状态，可以和表示过去某一时刻延续到现 （含“现在”）的一段时间状语连用。
如：for two years/ since1990/ since he came here
注意：for 之后接一段时间，since之后接过去的一个时间点或从句（从句常用一般过去时）
如：1.We have studied English for three years.
2. I have lived here since I was born.
3. They have been good frends since two years ago.
试一试，用所词的正确形式填空。
1. I ______ ______ (live) here since I was ten years old.
2. I _______ (live) here in 1998.
3.--______ you _____ your breakfast ？(have) --Yes，I have.
4.---When _____ you ______ it？(have) --- 30 minutes ago.
5.Mr Li _____ _______ Chinese in our school for six years.(teach)
6.---How long _____ you _____ Guming ( know)
---For about two years.
lived
have lived
Have
have
did
has
have
had
taught
known
想一想，下列每小题有一处错误，并改正。
1.He has left Beijing for many years.
_________
2.I have taught English since ten years.
_____________
3.Oh，hurry up，the film has begun for ten munites.___________
4.Our Chinese teacher has come to our school since five years ago.____________
5.How long has your father gone to Nanning
________
has been away from
________
__________
ten years ago
___________
has been on
_____________
has been in
________
been in
（二）表示短暂动作的瞬间性动词，如come、go、buy 等的完成时态就不能与for、 since 等表示一段时间的状语连用，但可以与这类词相应的延续性动词 或短语连用。
说明：
1 瞬间动词又叫非延续性动词或终止性动词，它可以有现在完成时态，但不可以接一段时间；如果要接一段时间，就必须把它转换成相应的延续性动词。
巧记10个瞬间性动词的转换
“开始离去借来还，出生入死买到家”
1 begin be on 6 return be back
2 leave be away from 7 join be in/be a member of
3 go be in/off 8 die be dead
4 borrow keep 9 buy have
5 come be in/here 10 arrive be in/ here
类似的转换还有：fall asleep—be asleep
move there—be there
open —— be open
mayy---- be married 等
have /has been to和have / has gone to 的用法区别
1 “ Have /has been to+地名 ”表示曾经去过某地，说话时已经回到说话地点， 常与once 、twice、ever、never 等时间连用。
2 “have / has gone to +地名 ”表示去某地了，现在没有回答，人不在说话地点。
巧记： been to ，gone to 意不同，两者用法要记清；
have been to + 地名，曾经到过某地行；
have gone to + 地点，到某地去了一走远。
用have /has been to和have / has gone to填空
