Turning off a device won’t stop it from using power.
Eating local food isn’t always better for the environment.
It’s not always better to take a shower than a bath.
Devices turned off go into stand-by mode and still use power.
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.
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.

1 Which of the “green truths” surprises you most Give your reasons.
2 Are you aware of any other “green truths” that are not true Share them with the class.
When you turn off a device,it stops using power. Usually I just turn off my television before going out,thinking it is a safe and green way. I don’t know it’s still a waste of energy.
Bike-sharing is a green method of transportation and provides a user-friendly experience. However,it causes the energy to be wasted if the bikes are thrown away by the roadside.
Think & Share

3 How “green” are you Share your “green actions” with the class.
4 What can you do to become “greener”
I usually try to save energy and water in my daily life. For example,I always turn off the lights when I leave a room. I walk or ride a bike instead of taking a bus or a taxi. I take a cloth bag when I go shopping.
I can stop using the things that can be used only once. I can unplug the TV set before I go out. I can stop people from producing power from coal.

1 Use these questions to help plan your talk.

·Why is it not completely true
·What can you do to become “greener”
2 Organise your talk following the steps below.
·Start your talk by stating the topic.
·Describe your chosen“green truth”in more detail.
·Explain why it is not completely“green”.
·End your talk by encouraging your audience to become “greener”.
3 Give your talk to the class.
Work in groups. Give a talk about one of the “green truths” in the passage.
Post-reading
I’m going to talk about one of the “green truths”—Paper shopping bags are better than plastic ones. As we all know,plastic bags cause litter and are a danger to wild animals,which mistake them for food. It takes hundreds of years for plastic to break down,but much less time for paper. Because of this,we think paper bags are the better environmental choice. However,making a paper bag uses four times as much energy as making a plastic bag and up to three times the amount of water. The process also produces more greenhouse gases. In fact,both kinds of bags are bad for the environment. So,why not take a reusable bag to become “greener” when going shopping
