五、核心语法精讲:节能建议与结果表达
1. should:应该
should 用来提出建议、责任或正确做法,后面接动词原形。
肯定:主语 + should + 动词原形:We should save energy.
否定:主语 + shouldn’t + 动词原形:We shouldn’t waste water.
注意:should 没有人称和数的变化,he/she 后仍用 should。
句式
结构
例句
肯定句
主语 + should + 动词原形
We should save energy.
否定句
主语 + shouldn’t + 动词原形
We shouldn’t waste resources.
一般疑问句
Should + 主语 + 动词原形...?
Should we turn off the lights?
简短回答
Yes, 主语 + should. / No, 主语 + shouldn’t.
Yes, we should.
2. can:能够/可以
can 后接动词原形,表示能力、可行方法或建议:
We can use green energy. We can also walk to school.
否定:We can’t waste energy.
提问:Can we save water by taking quick showers?
3. will:将会产生的结果
will + 动词原形,表示将来可能发生的结果或后果:
Save energy, then we will use fewer resources.
Small changes will make a big difference.
注意:will 后使用动词原形,不说 will uses 或 will made。
4. Let’s:让我们……
Let’s + 动词原形,用来提出一起做某事的建议:
Let’s follow the “3R” rules.
否定建议:Let’s not waste water.
回答:Good idea! / OK! / All right!
5. use...to...:用……做……
use + 事物/能源 + to + 动词原形:
We use green energy to light, heat and cool our homes.
We use water power to make electricity.
同一句中 to 后可以并列多个动词:to light, heat and cool。
6. fewer + 可数名词复数
fewer 表示“更少的”,后接可数名词复数:fewer resources, fewer cars, fewer plastic bags。
不可数名词“更少”用 less:less water, less energy, less pollution。
7. 易错提醒
① should/can/will/Let’s 后用动词原形:should save, can use, will help, Let’s follow。
② turn off 表示“关闭”,unplug 表示“拔掉插头”,二者不能混用。
③ energy、water、electricity 通常是不可数名词,不说 many energy 或 two waters。
④ 3R 的三个词形式要统一:Reduce, Reuse, Recycle。
六、3R 节能准则
规则

具体做法
Reduce 减少
