3. Local produce sometimes might use more energy and produce more greenhouse gases than produce grown a long way away-even taking into account its transport.
4. If you spend more than eight minutes in a shower, you'll use as much water as in a bath-about 50 litres of water.

Introduction
Body
Conclusion
Green truth 1
Green truth 2
Green truth 3
Green truth 4
Retell the passage based on four subheadings and some key words.
Green truth 1

Paper shopping bags are better than plastic ones.
Green truth 2
stand-by mode; electricity continues to leak; remove the plug
When you turn off a device, it stops using power.
Green truth 3
transported long distances; kept cold; production of the food; energy and greenhouse gases
Eating local food is good for the environment.
Green truth 4
shower time; bath size; eight minutes; 50 litres
It's better to take a shower than a bath.
In some cases, local produce might have used more energy and produced more greenhouse gases than produce grown a long way away - even taking into account its transport.
V-ed作后置定语
= that is grown a long way away
非谓语作让步状语
将……考虑在内
Paraphrase
Sometimes, even when we consider food transport, local food might have used more energy and produced more greenhouse gases than food that is grown a long way away.
在有些情况下，即使将运输的因素考虑在内，本地的农产品也可能比距离遥远的外地种植的农产品耗能更多，产生的温室气体也更多。
Work in groups. Give a talk about one of the “green truths” in the passage.
