现在完成时 The Present Perfect Tense
定义：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。某些动词的现在完成时可表示过去某一时间开始一直持续到现在（包括“现在”在内）的动作或状态，可以和表示延续的时间状语连用。表示持续动作或状态的动词多是延续性动词。
现在完成时的构成：
肯定句: 主语+have/has+过去分词+其他
否定句: 主语+haven’t/hasn’t+过去分词
+其他
一般 Have/Has+主语+过去分词+
疑问句：…？
肯定答语: Yes, 主格代词+have/has.
否定答语: No, 主格代词+haven’t/hasn’t.
动词过去式和过去分词的变化
规则变化：
1. 一般在动词词尾直接加ed。如：
pick → picked → picked; wish → wished → wished; stay → stayed → stayed
2. 以不发音的e结尾的动词后面加d。如：like → liked → liked; hope → hoped → hoped; phone → phoned → phoned
3. 以“辅音字母 + y”结尾的动词，变y为i，再加-ed如：
study → studied → studied; hurry → hurried → hurried; reply → replied → replied
4. 词尾只有一个辅音字母的重读闭音节动词，要双写这一辅音字母，再加-ed如：stop → stopped → stopped; clap → clapped → clapped
不规则变化：
5. 以不变应万变。如：
let → let → let; put → put → put; read → read → read
6. 若中间有双写e，则去掉一个e，单词末尾再加t。如：
feel → felt → felt; keep → kept → kept; sleep → slept → slept
7. 结尾的字母d变t。如：
lend → lent → lent; build → built → built; send → sent → sent
8. 变为以-ought或-aught结尾。如：
buy → bought → bought; bring → brought → brought; catch → caught → caught; teach → taught → taught
already 已经，常用于肯定句中。一般置于助动词have/has之后，过去分词之前，但也可以放在句末。
我已经看过这部电影了。
I have already seen the film.
我已经解决了这个问题。
I have already solved this problem.
我已经做完家庭作业了。
I have finished my homework already.
yet，在现在完成时句型中常置于句末。
1) 已经，常用在疑问句中。
琳达已看过这本书了吗
Has Linda read the book yet
你完成家庭作业了吗？
Have you finished your homework yet
2) 还，仍然，常用于否定句句末。
他还未开始工作。
He has not begun to work yet.
just 刚刚，常用于肯定句中。一般置于助动词have/has之后，过去分词之前。
我刚吃过午饭。
I have just finished lunch.
我们刚刚听说她的婚讯。
We have just heard of her marriage.
同学们要注意现在完成时与一般过去时的区别。虽然这两个时态都和过去发生的事情有关，但是现在完成时强调这一动作与现在的关系，如对现在产生的结果、影响等，而一般过去时只表示过去的事实，不表示和现在的关系。如：
I went home at 10:00 yesterday. I have got home now.
我昨天十点回家的。现在我已经到家了。
I have already finished my homework.
I finished it an hour ago.
我已经写完作业了，我是一个小时之前写完的。
