Using LanguageThe Return of Dinosaurs1.Do you like dinosaurs?Warming up 2. Can we see them in real life? Why?Look at the following pictures and think
which film they are from ?Do you think it possible for people to clone a dinosaur? Why?Understand the passage and know more about the cloning of dinosaurs and its problems.
Use your own words to explain why dinosaurs can’t be cloned successfully.
Strengthen your understanding of the passage by means of vocabulary and grammar exercises.
List the reasons to bring one of four extinct animals back to life.
Learning aims Aim One: Understand the passageYou should: skim the whole passage for the

Thirdly, ____________________________.
So I think _________ would be the best choice to be brought back to life both for pleasure and for food. Task 7Writing Sample writing Let’s bring the dodo back to life
The dodo is the most suitable animal to be brought to life. Here are the reasons:
Firstly, it’s friendly and not aggressive, so it can be kept as a pet for children. Secondly, its large eggs and tasty meat can be served as food. Thirdly, farmers can sell its feathers as decoration.
So I think the dodo would be the best choice to be brought back to life. The End Thanks For Your Attention!
