9、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 stayed2. 以不发音的e结尾的动词后面加d。如：like liked liked; hope hoped hoped; phone phoned phoned3. 以“辅音字母 + y”结尾的动词，变y为i，再加-ed。如：study studied studied; hurry hurried
10、hurried; reply replied replied4. 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 read6. 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 slept7. 结尾的字母d变t。如：lend lent lent; build built built; send s
11、ent sent8. 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
12、)+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?
