Some 2 ESO students creations on what an eco-city is not:

                 

Original Riddle:

I have streets but no pavement,
I have cities but no buildings,
I have forests but no trees,
I have rivers yet no water.

What am I?

Rewritten Riddle:

I have streets with no trees

I have cities but dirty buildings

I had forests but they burned

I had rivers with they were polluted

What am I? 

 

By a 1 Bachillerato group (thinking in Huelva):

Original Riddle:

In marble walls as white as milk,
Lined with skin as soft as silk,
In a fountain crystal clear,
A golden treasure does appear.
There are no doors to this stronghold,
Yet thieves break in and steal the gold.

What is it?

 

Rewritten version:

In cardboard walls as  soft as  velvet

Lined with paint as ecological as Everest

By a river as clear as a day

a golden city does appear

There is no pollution

Yet arsonists came in and blackened our evolution

                                                                                           Which city is it?
