二、总结与解析
现在完成时的结构为：have/has + 过去分词。它常用于以下几种情况：
1. 表示从过去某一时间持续到现在的动作或状态
- 常用时间状语：since, for, ever, never, already, yet, just
- 例句：I have lived here since 2010.
2. 表示过去发生的动作对现在有影响或结果
- 例句：She has lost her key.（她现在没有钥匙）
3. 表示某人曾经做过某事
- 例句：Have you ever been to Japan?
在使用现在完成时时，需要注意动词的过去分词形式，尤其是不规则动词的变化。例如：
- go → gone
- see → seen
- eat → eaten
- travel → traveled
同时，already 和 yet 的位置也需要特别注意。通常 already 放在动词前，而 yet 放在句尾。
三、常见错误提醒
1. 混淆现在完成时和一般过去时
- 错误：I saw that movie yesterday.
- 正确：I have seen that movie.（强调对现在的影响）
2. 忘记使用“have/has”
- 错误：He went to school.（一般过去时）
- 正确：He has gone to school.（强调现在状态）
3. 错误使用时间状语
- 错误：I have lived here for two days ago.
- 正确：I lived here two days ago.（一般过去时）
