Step 2 现在完成时
构成：助动词have / has+ 动词的过去分词，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。
规则变化：
1. 一般加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; 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;
4. 以辅元辅结尾的，双写再加-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
句式：
1. 肯定句：主语 + have / has + 过去分词 (+ 其它)
2. 否定句：主语 + have / has + not + 过去分词(+ 其它)
3. 一般疑问句：have/ has + 主语 + 过去分词(+ 其它)
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。
e.g. –Have you had your lunch yet
–Yes, I have. I’ve just had it. (现在我不饿了。)
时间状语：already, yet, just, ever, never, before
2. 表示动作或状态从过去某一时刻开始，一直延续到现在，而且可能还要继续下去。
e.g. I haven’t seen her these days.
I’ve known Bob for three years.
I’ve been at this school for over two years.
already和yet都可以作为现在完成时的标志词，但它们的用法不同。
◆already一般用于肯定句中。◆yet一般用于疑问句和否定句中。
