资源简介

现在完成时
知识提炼
概念：
①表示过去发生并且已经完成的动作对现在造成影响或后果；
②过去某一时间开始并一直持续到现在并且有可能还会持续的动作或状态。
I have finished my homework. (过去+完成+影响)
I have taught English for three years. (过去+持续)
二、基本结构： have/has done(动词的过去分词)
注：现在完成时中have/has 是助动词，不是实义动词
三、动词过去分词的变化规则：
规则变化： （同过去式规则变化一致）
直接加ed。
work →worked →worked
以不发音e结尾的动词，在词尾后直接加d。 　　
live→lived→lived change→changed→changed
以“辅音字母 + y”结尾的动词，把y改i，再加ed。
study→studied→studied cry→cried→cried
重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，
再加ed。
stop→ stopped→ stopped prefer→ preferred→ preferred
不规则（书本）
四、句型转换
肯定句： 主语+have/has +done
助动词have/has可与前面的主语缩略为’ve, ’s, 如they’ve, he’s
否定句： 主语+have/has+ not+ done
have not=haven’t has not=hasn’t
一般疑问句： Have/Has+主语+done...
回答： Yes, 主语+have/has. No, 主语+have/hasn’t.
特殊疑问句： 特殊疑问词或词组+have/has+主语+done...
常考易错点
have/has gone to、have/has been to和have/has been in区别
（1）have /has gone to“去了未回”
Tom has gone to America.
（2）have /has been to“去过已回” 常与表示次数：twice, once和just, never, ever的时间词连用。
Tom has been to America twice.
（3）have /has been in去了某地，并待在那。常与for/since的时间词连用。
Tom has been in America for 5 years.
注意：当地点为home/here/there/abroad或以where开头的问句时，记得要
省略介词。
Where have you been
He has gone home.
六、时间标志词
already（已经）; yet（“仍，还”）; just（刚刚）
I have already finished my homework. (already 肯 中/末)
=I have finished my homework already.
Have you finished your homework yet (yet 否/疑问 末)
I haven't finished my homework yet.
I have just finished my homework. (just 肯 中)
注：just now 为一般过去时的标志词，表示 “刚才”
I turned off the light just now.
ever; never（从未）
Have you ever been to China (ever 疑/肯 中)
I have ever been to China.
I have never been to China. （never否 / 中）
For; since（+过去时间点/ ago/ 从过）
I have been in China for 3 years. (for+一段时间)
I have been in China since 3 years ago. （since+时间点）
Before; 次数；so far; recently; in the past/last/ recent few years, up to now

I have been to England three times. (次数)
So far, I have had 5 pets. (so far)
