Nowadays people can see dinosaurs only in the films. As time goes by, more and more wild animals are becoming out of sight. 1 To our great comfort, scientists are taking the first step. All around the world, teams of scientists are racing against time to collect DNA material from endangered animals before they disappear. They hope that if it is frozen and stored, it could help them to one day bring an extinct (灭绝的) animal back to life with cloning (克隆) technology.
2 It was created by the Zoological Society of London, the UK’s National History Museum and the University of Nottingham. Scientists collect DNA material from animals in zoos and those in the wild and freeze and store them at the University of Nottingham.
Frozen Ark says that it could provide a back-up plan if all other conservation（保护）efforts fail.
3 “Like Dolly the sheep, although scientists do not like to talk too much about this, there is a very real possibility that we might be able to one day bring back an extinct animal. It will come true.” said Ann Clark from Frozen Ark.
While bringing extinct animals back from the dead sound like science fiction, thanks to recent developments in cloning technology, it is much closer to reality than you might think. 4 The animal died short after birth, but it marked the beginning of this new conservation biology. 5
But as long as action is taken by scientists, I’m sure our future generations will still be able to see those lovely animals.
A. There is a long way to go.
B. This program was called Frozen Ark.
C. It’s really hard to froze and store animals.
D. Many extinct animals have been brought back.
E. Nothing in the world is that easy at the beginning.
F. So it’s high time that we did something to protect them.
G. In 2009, a Spanish team made a clone of the extinct Pyrenean ibex.
