### 🔑 核心结构速记
现在完成时 = **have/has + 过去分词**
– 规则动词：have **started**, have **studied**（加-ed）
– 不规则动词：have **done**, have **seen**, have **written**（牢记动词第三形式）

### ⚡ 四大核心用法解密
#### 1️⃣ 过去动作影响现在
> 过去动作的结果直接关联当下
✅ *I’ve driven from Boston to Pittsburgh many times, so I’m familiar with the route.*
（熟悉路线是当前状态）
🚫 **禁用场景**
– 封闭时间段：*In my childhood, I **climbed** trees.*（童年已结束）
– 过去习惯：*We **used to** walk along the railroad tracks.*
#### 2️⃣ 泛化经历（不指定时间）
> ✅ *I’ve been to Paris a few times.*
🚫 **具体时间需切时态**：
*The last time I **visited** was in 2023.*
*I first **went** when I was 16.*
#### 3️⃣ 连接未来的可能性
> 可能重复的经历用现在完成时
✅ *I’ve been to Squam Lake and hope to visit again.*
❌ **拒绝重复则切一般过去时**：
*- Have you been to the new cafe?
– Yes, but I **didn’t like** it. They **mixed up** my order.*
#### 4️⃣ 延续事件测量（+进行时）
> 现在完成进行时：have/has + **been + V-ing**
✅ *I’ve **been living** here for 3 years.*（近期）
✅ *I’ve **lived** in Massachusetts since 2001.*（长期）
🚫 封闭期：*I **lived** on a steamboat for half a year.*

### 🎯 美式英语特别提示
#### ▶️ 证据推理法
> 根据迹象推测用现在完成进行时：
*It smells like chemicals. **Have you been cleaning?***
*You look tired. **Have you been staying** up late?*
#### ▶️ 无证据用一般过去时
*Why are you in pajamas? **Did you go** to work?*
*The trash is full. **Didn’t you take** it out yesterday?*
#### ▶️ 高频简化现象
美国人更倾向用一般过去时：
* **Did** you ever lose your phone?*（更常用）
* **Have** you ever lost your phone?*
> 强调已完成动作常加副词：
*- **Did** you turn in the report?
– Yeah, I **just finished** it.*
