Last weekend, I took part in a forest clean-up activity. It was organized by Green Hope, an organization devoted to protecting forests. At first I didn’t want to take part in the forest clean-up activity , but then I thought, “What if nobody goes ” Our team leader, Joe, took us to a forest outside the city. I was sad to see litter everywhere. There was a “No littering is allowed here” sign at the entrance to the forest, but that didn’t stop people from throwing their rubbish on the ground.
(

(

Joe divided us into two groups: one group cleaned up the north side of the forest, and the other group cleaned up the south side of the forest. We worked for several hours and we were happy to see that the forest looked cleaner than it had looked before. It was absolutely worth our effort! There’ll be another clean-up activity in the green belt next Saturday. You can find Joe and sign up if you’re willing to help. Everyone who takes part in the activity will receive a medal. I’ll join you too if I have time.

Let’s continue Jack and Henry’s conversation on designing a brochure about protecting the environment by using ellipsis where possible.
Role playing
In pairs, describe the pictures below using ellipsis to call for the protection of the environment. Use the example to help you. You can draw a picture and think of a slogan.
B3
a word or phrase that is easy to remember, used for example in advertising to attract people's attention or to suggest an idea quickly
Practice
A smiling kid is drawing a green tree: ideal world
Blue sky and shining sunshine: good environment
Polluted air, dark sky: serious pollution
Factories and dead trees: cause and consequence of pollution
When the water is too dirty to drink and the air too polluted to breathe, will you be able to look at your children and say, “what a beautiful world!”
How to make a slogan
“Give a hand to wildlife”
A bicycle, made by leaves, daily transport, eco-friendly
Upper leaf: green, green energy, trees, clean sky
Lower leaf: yellow, factories, polluted air, no creatures
We should use public or eco-friendly transport for protecting environment
Protecting environment is urgent, new energy new life
Your turn
Show us your calls, and give some suggestions to improve the calls.
Review the rules of ellipsis and draw a picture and think of a slogan to call for the protection of the environment.

Why does the documentary show these figures
Of the 390,000 plant species known to us, more than 40,000 can be found in the Amazon. This tall and ancient brazil nut tree produces nuts that we can eat; these water lilies are big enough to lie down on. The forest's different levels support an unbelievable variety of wildlife. At the bottom, there is a system of roots beneath the ground. Above that is the mass of leaf litter on the dark forest floor. The next level is made up of shorter plants with large leaves. Then there are the towering ancient hardwoods, and finally the tops of the tallest trees many metres above the ground. Each level of the forest forms its own little world, home to different kinds of living things.
Read Paragraph 3 and complete the mind map about different levels of the rainforest.
Read Paragraph 4 and complete the following chart about the food chain in the rainforest.

The documentary script compares the size of the Amazon rain forest with that of China, and the length of the Amazon River with that of the Yangtze River.
Why
Making comparisons with familiar places or objects will help readers gain a better understanding, and makes the information more precise and accurate.
B3
Find these comparisons in the script and think of similar comparisons for the figures below.
With an area of around 6 million square kilometres, the Amazon rainforest is more than half the size of China.
The Amazon River, from which the rainforest gets its name, is close to 6,400 kilometres in length—roughly 100 kilometres longer than the Yangtze River.”
Here are some expressions used to make comparisons:
the same size/length as …
as large/long as …
more than/larger than/longer than …
twice/three times as large/long as …
Practice
