演讲 & 设备描述课
一、描述一件家里设备：COFFEE MAKER（实体描述三步）
第一步 · 整体定位 + 特征描述（定语从句管够）
I was tired of mediocre coffee, so I bought this coffee maker a couple of days ago. I'm looking for a basket that contains coffee grounds, with a handle, for a coffee maker（…也可以直接用：a basket that holds the coffee ground）.
第二步 · 部位说明（a part where 句型 = 万能解释）
- portafilter：a basket that holds coffee grounds, with a handle（手柄粉碗）
- group head：a part where the coffee ground meets hot water（冲煮头：咖啡粉遇到热水的地方）
- carafe：a metal kettle / container that holds the brewed coffee（咖啡壶）
第三步 · 操作 + 感受
I like this clicking sound when I take the portafilter and lock it into the group head — which is a part where the coffee ground meets hot water. Then I place a carafe underneath… Everything just clicks（刚刚好）. It's a great way to start off your day.
同义动词组（替换不重复，LR 高分点）
- contains / holds / carries / bears（装着）
- fine grind（细磨粉）↔ coarse（粗磨的，注意跟 hoarse 沙哑的区分）
- cold brew / coffee ground（咖啡渣）/ group head
早起话题接口（Do you get up early? / What's your morning routine?）
coffee wakes me up / cheers me up / boosts me up（一杯咖啡提神三连）；brush my teeth → make coffee → 重启（reboot）一天的节奏 —— 描述设备时顺带把 P1 的"早起/作息"也练了。
二、演讲结构模板（PowerOcean 家用储能产品示范）
1. Greeting + 目的（30 秒）
Good morning! First of all, how's everyone doing? To be honest, I'm genuinely excited about what we're going to share today.
2. AGENDA（先讲啥后讲 —— first…and then）
What we'll cover today: first, your energy challenges; and then, what PowerOcean is — and how it works.
3. THE CHALLENGE（痛点 → 达成共识）
Your bills keep climbing — and the grid isn't getting more reliable. Electricity prices: rising, year after year. Outages: rare — until the one day they aren't.
We both know… let's be honest about where we are: it's the era of every price skyrocketing, including electricity. If you have solar panels but no energy storage, it doesn't really help…（don't worry, we've got you）
4. THE ANSWER（产品三连 + 一句话定位）
Meet PowerOcean — a home energy system that thinks ahead: All-in-one: solar + storage + smart control. Three-phase: built for bigger homes and heavier loads. Modular battery stacks: start small, expand when ready. One system — every watt working for your home.
5. 比喻讲原理（把术语翻译成画面）
- 太阳能不配储能 = 水倒进海里：It's like water being poured into the ocean（后置定语 being poured…）
- 逆变器 = 系统的心脏：the inverter converts DC into AC, making the energy usable by home appliances… to put it simply, it's like the brain and heart to a human being.
- 万能比喻句式：X is like the salt on every table / a condiment to every soup（处处都需要、缺了不行）
6. 收尾随意切换（口语考场的"答题结束感"）
…So that's why we recommend PowerOcean. （回到生活题：Do you like reading? 等 → 用 4 字诀接）
三、本课术语与句式清单
- 能源词：pain point（痛点）、energy bill（电费账单）、backup electricity（备用电）、solar panel（太阳能板）、energy storage（储能）、three-phase（三相电）、modular battery stacks（模块化电池堆）、inverter（逆变器）、DC/AC（直流/交流）、current（电流）、grid（电网）
- 定语从句链：energy generated by solar panels on your rooftop；DC usable by home appliances（后置定语前移修饰）
- 比喻句型："X is like Y to Z" / It's like…being…（被动进行时的画面）
- 演讲衔接：good morning → how's everyone doing → to be honest → agenda → challenge → answer → 比喻收束
