情景导入
周末，小雨一家去杭州动物园。她一边看一边用英语"现场直播"："Look! The monkey is climbing the tree! The pandas are eating bamboo!"（看！猴子正在爬树！熊猫们正在吃竹子！）
弟弟大声喊叫，妈妈轻声提醒："Talk quietly. The animals are sleeping."（小声说话，动物们正在睡觉。）"正在做某事"用英语怎么说？这就是本课的主角——现在进行时。
核心词汇
动作类（原形 → ing 形式）：
| 单词 | ing 形式 | 意思 | 例句 |
|---|---|---|---|
| eat | eating | 吃 | The panda is eating. |
| drink | drinking | 喝 | He is drinking water. |
| play | playing | 玩 | They are playing football. |
| run | running | 跑 | The tiger is running. |
| swim | swimming | 游泳 | The fish is swimming. |
| take | taking | 拿；拍 | She is taking pictures. |
| sleep | sleeping | 睡觉 | The cat is sleeping. |
课堂提醒类：work quietly（安静地做作业）、talk quietly（小声说话）、keep to the right（靠右行走）、keep your desk clean（保持课桌整洁）。
句型与语法
第一步：结构公式——表示"此时此刻正在做"的动作：
- I am doing my homework. / He is reading. / They are singing.
第二步：动词 ing 三条变化规则：
- 一般情况直接加 ing：eat → eating, play → playing；
- 以不发音 e 结尾，去 e 加 ing：take → taking, have → having；
- 重读闭音节双写末尾字母再加 ing：run → running, swim → swimming。
第三步：问答：
- What are you doing? — I am listening to music. （你在干什么？——我在听音乐。）
- What is he doing? — He is playing football. （他在干什么？——他在踢足球。）
信号词：句子里出现 Look!（看！）、Listen!（听！）、now（现在），十有八九用现在进行时。
听说训练
动物园直播问答（和同伴问答）：
- A: What is the monkey doing? （猴子正在干什么？）
- B: It's climbing the tree. （它正在爬树。）
- A: What are the pandas doing? （熊猫们正在干什么？）
- B: They're eating bamboo. （它们正在吃竹子。）
电话情景：Hi! What are you doing? — I'm doing my homework. What about you?
辨析对比
- I play football every day. 一般现在时——说"经常、每天"的习惯；
- I am playing football now. 现在进行时——说"此时此刻"正在做；
- 经典陷阱：He is running now. 别写成 He is run 或 He running——be 和 ing 一个都不能少。
文化角
英语国家的图书馆里常能看到 Quiet, please.（请安静）的提示牌，和课本里的 Work quietly! 一模一样。在杭州图书馆、少年宫自习室，我们同样要轻声细语——礼貌提醒别人时，英语常在句尾加 please，语气就温和多了：Talk quietly, please.
易错点
- 丢掉 be 动词：He playing football. ❌ → He is playing football. ✅
- 丢掉 ing：She is read a book. ❌ → She is reading a book. ✅
- 双写规则忘记：run → runing ❌ → running ✅；swim → swiming ❌ → swimming ✅
- be 动词配错：They is dancing. ❌ → They are dancing. ✅（复数主语用 are）
考点
- What is/are ... doing? 的问答匹配（必考）；
- 动词 ing 形式的拼写变化：taking / running / swimming / having（高频考点）；
- am / is / are 与主语的搭配；一般现在时与现在进行时的区分（play vs is playing）。
诵读 Read Aloud
Part 1 · 动物园直播
It is Sunday. My family is at the zoo. Look! The monkey is climbing the tree. The elephant is drinking water. Two pandas are eating bamboo. A rabbit is jumping. What a fun day!
Part 2 · 安静的教室
It is three o'clock. We are in the classroom. The teacher says, "Work quietly, please." Amy is reading a book. Mike is writing. I am doing my exercises. Everyone is working quietly.
诵读小贴士：Part 1 是"看图写话"的标准模板（先说时间地点，再逐个描述动作）；朗读时注意 be 动词的缩写读法：I'm / He's / They're。
