Unit 10 核心主题：谈论拥有的经历

本单元围绕“拥有某物已经多久了”展开对话和讨论，学习如何用英语表达“从过去开始，持续到现在的动作或状态”。

Part 1: 核心语法 - 现在完成时

这是本单元的重中之重！你需要区分它和一般过去时的区别。

用法：表示“持续”

这是本单元的核心用法，表示一个动作或状态从过去开始，一直持续到现在，并有可能继续下去。

结构： 主语 + have/has + 动词的过去分词 + for + 时间段 / since + 时间点
标志词：
- for + 一段时间 (e.g., for three years, for two weeks)
- since + 一个时间点 (e.g., since 2025, since last month, since I was a child)

对比：现在完成时 vs. 一般过去时

这是最容易混淆的地方,一定要搞清楚！

特征	现在完成时	一般过去时
时间	不确定的过去时间，强调对现在的影响或结果，或动作的持续性。	确定的过去时间，强调过去某个时间点发生的动作。
标志词	`for`, `since`, `already`, `yet`, `just`, `ever`, `never`, `so far`	`yesterday`, `last week`, `in 2025`, `two days ago`, `at that time`
例子	- I have had this book for a week. (我拥有这本书已经一周了，书现在还在我手里。) - He has lived here since 2025. (他从2025年就住在这里了，现在还住在这里。)	- I read that book yesterday. (我昨天读了那本书，书可能已经读完了，也可能已经还回去了。) - He lived there in 2010. (他在2010年住在那里，那是过去的事了，现在可能不住在那里了。)

现在完成时的其他常见用法

除了表示“持续”,它还有两个重要用法：

表示“过去发生，对现在有影响”的动作
