Jurassic Park could become a reality with dinosaurs making a comeback after a discovery last week. Scientists found remains of a dinosaur’s blood vessels（血管）and cells .In theory, DNA from these cells could be used to clone the longdead dinosaur.

A team from North Carolina State University found the remains in a fossil(化石)of the leg bone of a Tyrannosaurus rex（暴龙）in Montana, US.

The last dinosaurs on Earth died some 65 million years ago, but they left bits of themselves behind wherever they lived. Around the world ,dug-up bones and fossils have given scientists many ideas about what the animals were like.

Preserved by minerals, the newly discovered leg bone was hard. So the scientists used a liquid to dissolve（溶解）the minerals. A week later, the remaining material was soft and stretchy（有弹性的）,which surprised the researchers.

Some of the materials appeared to be a network of blood vessels. Out of these, the researchers were able to squeeze(挤出)tiny , round, dark-red and deep-brown structures that seemed to be ancient blood cells.

Scientists are overjoyed by this discovery because most fossils come from hard body parts, like bones and shells, which last a long time. Soft tissues, like skin, muscle, and organs are very hard to find because they tend to break down more quickly.

Scientists think that the new discovery will help them to better understand how fossils form. Future finds should also help flesh out how the dinosaurs lived.

They were also very excited by the possibility of having some dinosaur DNA.From that scientists could create a real life “Jurassic Park”.

In the Hollywood movie, scientists reproduced dinosaurs from the DNA they found in a mosquito fossil and disaster soon followed.

Scientists are excited _________________________ .

A. because they have got dinosaur DNA

B. about making a movie called “Jurassic Park”

C. because they found the liquid to dissolve fossils

D. because it,s very hard to find soft tissues in fossils

C. how the dinosaur lived D. how to get dinosaur DNA

What does the underlined phrase“flesh out”mean in the article?

A. add more details or information to B. take more photos of

C. make the public know more about D. find the answer to

Why is the latest discovery very important?

A. It could make it possible to make dinosaurs return to the former position.

B. It could throw light on how dinosaurs lived many years ago.
