I’ve been at this school for over two years. 时间状语 already, yet, just, ever, never, before 构成 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： 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 句式 1. 肯定句：主语 + have / has + 过去分词 (+ 其他) 2. 否定句：主语 + have / has + not + 过去分词(+ 其他) 3. 一般疑问句：have/ has + 主语 + 过去分词(+ 其他) 4. 特殊疑问句： 1) 特殊疑问词 (不是句子主语) + have / has + 主语+过去分词 (+ 其他) 2) 特殊疑问词(是句子主语)+have / has+过去分词(+ 其他) 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。如： We have already cleaned up our classroom. 注意：already 用于疑问句中时通常表示惊奇。如： Have you finished your homework already? I can’t believe it. ◆yet 一般用于疑问句和否定句中。如： Have you seen her yet?
