To inform readers of some common green truths and thus remind us to check common ideas and opinions to see what’s really green.
Read the passage fast and try to figure out the structure of it.
Introduction
Conclusion
Activity 3
Devices turned off go into
stand-by mode and still use power.
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.
Think of the title “What’s really green ” and share your opinions.
“Green”: if you say someone or something is green, you mean they harm the environment as little as possible.
Most of us try to live a green life but if we just follow some advice blindly, we won’t really protect our environment. Only by thinking critically and learning broadly can we reduce harm to our mother nature.

What message does the author really want to convey in the unit？
Think and share
Humans couldn’t live without Mother Nature. We must give priority to her, and then we can survive in a sustainable way. On no account should any activity of environmental protection be conducted by sacrificing our mother nature, such as exploiting wild areas, disturbing the peaceful life of wild animals.
Real environmental protection should consider Mother Nature first and then us human beings rather than the other way round.
It is essential for us to equip ourselves with adequate knowledge about environmental protection. We should obey the rules of nature instead of protecting the environment out of our own need or by our own assumptions.
You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental costs.
The admirable goal of living sustainably requires plenty of thought on an ongoing basis.
Respect but with no FEAR
Employ but not to DESTROY
Appreciate but away from GREED
Love is HARMONY

Dear Friends,
We are writing this letter to raise your awareness of the need to protect our planet. You can help simply by participating in the No Bottled Water campaign.
People tend to think bottled water is cleaner and more convenient. However, they may not know that according to scientific research, millions of tons of plastic are used worldwide to make water bottles each year. The plastic can take hundreds of years to break down.
If you are worried about the effects of bottled water on the Earth, we would like to suggest you take the following steps.
1. Carry your water in a sustainable, reusable bottle. In this way, you don’t need to buy bottled water.
2. If you have to purchase a plastic bottled beverage, recycle the bottle after use.
3. Ask your family members and friends to take part in this campaign.
One possible version
Everyone is responsible for making our planet cleaner and
better by doing what we can. Let’s start NOW.
With best wishes,
Class 18
