现在完成时是由“助动词have

has+
动词的过去分词”构成的，规则动词的过去分词构成与过去式相同，不规则动词的过去分词则需逐个记忆。
动词的过去式的变化和过去分词的变化并不完全相同。我们对它们作了一个大致的分类。
(注：例子中单词的变化顺序为：动词原形
→
动词的过去式?
→
动词的过去分词)
一、过去式和过去分词的变化相同
规则变化：

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：

caught;
teach
