情景导入
周末晚上，你给好朋友打电话：— What are you doing? （你在干嘛呢？）— I am doing my homework. （我正在写作业。）
注意"正在"两个字——动作此时此刻正在进行，还没结束。这就是现在进行时的核心含义。对比一般现在时：I do my homework every day.（我每天都写作业——说的是习惯，不是"此刻"。）一句话记住：现在进行时 = 说话的这一刻，动作正在发生。
核心词汇
现在进行时的信号词（看到它们优先考虑现在进行时）：
| 信号词 | 意思 | 例句 |
|---|---|---|
| now / right now | 现在、就在此刻 | I am reading now. |
| at the moment | 此刻 | He is sleeping at the moment. |
| Look! / Listen! | 看！/ 听！ | Look! The bird is flying. |
高频动词及其 -ing 形式：read → reading，play → playing，run → running，swim → swimming，write → writing，make → making，lie → lying
句型与语法
基本结构：
- I + am doing；He / She / It + is doing；You / We / They + are doing
- 否定：be 后加 not → She isn't watching TV. 疑问：be 提前 → Are you listening? — Yes, I am. / No, I'm not.
动词 -ing 的四条变化规则（必须背熟）：
| 规则 | 说明 | 例子 |
|---|---|---|
| ① 一般情况直接加 -ing | 多数动词 | play → playing，read → reading |
| ② 以不发音 e 结尾，去 e 加 -ing | write、make 等 | write → writing，dance → dancing |
| ③ 重读闭音节，双写末尾辅音字母再加 -ing | run、swim 等 | run → running，sit → sitting |
| ④ 以 ie 结尾，变 ie 为 y 加 -ing | lie、die | lie → lying，die → dying |
例句体会：Look! The children are playing football. （看！孩子们正在踢足球。）/ Is it raining outside? — No, it isn't. （外面正在下雨吗？——没有。）
听说训练
看图说话游戏（一人做动作，其他人用现在进行时描述）：
- What is he doing? — He is running! （他正在跑步！）
- Are you sleeping? — No, I'm not! I am thinking. （没有！我正在思考。）跟读时注意 be 动词的缩读：I'm / She's / They're。
辨析对比
| 现在进行时 | 一般现在时 | |
|---|---|---|
| 含义 | 此刻正在发生 | 经常性、习惯性动作 |
| 时间状语 | now, right now, Look!, Listen! | every day, usually, often |
| 结构 | be + doing | 动词原形（三单加 s/es） |
| 例句 | He is reading now.（此刻在读） | He reads every night.（习惯） |
注意：like、love、want、know、have（拥有）等表示状态和情感的动词一般不用进行时。I am knowing him. ❌ → I know him. ✅
文化角
英语国家的人打电话时，开头常用现在进行时寒暄：What are you doing?（你在忙什么呢？）/ Am I calling at a bad time?（我打电话的时机不巧吗？）
易错点
- 漏掉 be 动词：He playing basketball. ❌ → He is playing basketball. ✅
- -ing 变化出错：run → runing ❌ → running ✅（双写）；write → writeing ❌ → writing ✅（去 e）
- 状态动词误用进行时：I am liking this book. ❌ → I like this book. ✅；be 动词与主语不一致：They is singing. ❌ → They are singing. ✅
中考真题
— Where is Tom? I can't find him anywhere.
— Look! He ______ under the big tree over there.
A. reads B. read C. is reading D. was reading
✏️ 点击查看解答
答案：C
解析：Look!（看！）是现在进行时的典型信号词，说明动作此时此刻正在进行，应用 be + doing 结构。主语 He 是第三人称单数，be 动词用 is，选 C. is reading。A 项是一般现在时（表习惯），B 项缺 be 动词，D 项是过去进行时，都与 Look! 提示的"当下"不符。
考点
- 七年级下核心时态，单选、语法填空、句型转换均高频出现；
- 中考命题点：① 信号词 now / Look! / Listen! 判断时态 ② -ing 变化规则（双写、去 e、ie 变 y）③ be 动词与主语的一致性。
