2017届高考英语一轮复习方案精品课件：第7讲 Unit7 《The Sea》（北师大版必修3）

　　Good morning, everyone，

　　My topic today is how to live a lowcarbon life. As we all know, the earth is becoming warmer and warmer due to the global climate change. Many people may think that a lowcarbon life is far away from us. However, every one of us can reduce our daily carbon emission by doing something.

　　Firstly, changing our previous living habit of wasting things is the first step. We can use energysaving electricity lights instead of the traditional ones, and turn them off when we don't use them.

　　第7讲 │ 美文欣赏 Never leave the water running when we don't use it. When we need to contact someone, it's better to send an email than use paper to write letters.

　　Use the public transport or ride bicycles instead of driving private cars when we travel somewhere. Even if we have to drive, we'd better plan it well in advance to avoid wasting fuel.

　　It is believed that the global climate change is due to the human activities. Only if we know what we do in our daily life and live a lowcarbon life can we make a difference. 第7讲 │ 美文欣赏【全品点睛】

　　①行文逻辑：揭示主题→ 简单分析→提出建议→呼应主题：呼吁大家过低碳生活。较好地使用了连接词，如：however，firstly, and等。

　　②词汇短语：运用了较高级的词汇和短语。如：warmer and warmer，due to，instead of，in advance等。第7讲 │ 美文欣赏 ③句式句法：运用了多样化的句式和句法结构。如：定语从句：As we all know；状语从句：when we don't use them，…when we don't use it (时间状语从句)；Even if we have to drive(让步状语从句)；祈使句：Use the public transport or ride…；主语从句：It is believed that…；倒装句：Only if we know what we do in our daily life and live a lowcarbon life can we make a difference.等。此外，非谓语动词：by doing，how to…，… the water running，to avoid wasting fuel的使用也大大提高了文章的档次。
