the chance of dinosaurs returning to the earthGreat Auk (1844)Aurochs (1627)Dodo bird (1755)Quagga (1883)DiscussionA sample reportLet’s bring the dodo back to life
The dodo is the most suitable animal to be
brought back to life. Here are the reasons：
Firstly, it’s friendly and not harmful, so we
can keep it as pet for children.
Secondly, its large eggs and tasty meat
could be developed for food.
Finally, farmers can sell its feathers as
decoration.
So I think the dodo would be the best
choice to be brought back to life.Assignments 1. Read the passage aloud and underline the sentences which are difficult for you to understand.
2. Write a short report about the reasons and benefits of bringing × × × back to life. (You may refer to the passage on P17)
