Were dinosaurs (恐龙) warm-blooded or cold-blooded? According to a new study, scientists have found that they were somewhere in the middle. This new study shows that dinosaurs were very different from most of today’s animals that are either warm or cold-blooded.6

“I think we were all surprised by this,” said Felisa Smith from the University of New Mexico. “The idea certainly took some getting used to.”

The last dinosaurs lived on the earth more than 60 million years ago. However, there is always more to discover about these ancient animals.

A study by a team of scientists led by John M. Grady of the university studied many different kinds of dinosaurs in their research. They looked at growth rate (比率), body temperature and body size of different kinds of dinosaurs.

How are warm-blooded animals different from cold-blooded animals? Warm-blooded animals like humans can control their body temperature. They eat a lot, and burn calories (卡路里) quickly. They have a more active lifestyle than cold-blooded animals. While cold-blooded animals such as snakes do not control their body temperature. Instead, they must use sunlight to keep warm, and they move much more slowly. Cold-blooded animals do not need to eat very much. Their bodies slow down in colder temperatures.

Dinosaurs were in the middle because they didn’t completely control their body temperature, but their body temperature didn’t only depend on the environment either. This helped dinosaurs and allowed them to live for so many years.

Besides dinosaurs, there are other animals that are not completely warm-blooded or cold-blooded, such as great white sharks.

Jayson Fann talks with a reporter about creating art with natural materials.

Reporter: What is your job?

JF: I’m an environmental artist, and I build human-sized nests. My nests are all over the world.

Reporter: (11)_________

JF: People can have dinner parties in my nests. They can also read and relax in them. Some of my nests even have several rooms, so people can also use my nests as hotel rooms.

Reporter: (12)_________

JF: First, I draw a design (设计图样) for the nest. Then I discuss the design with my customer. After the design is finished, I collect wood and work with a team to build it.

Reporter: (13)_________

JF: I use eucalyptus (桉树) wood, which is soft and easy to bend (弯曲) when it is young and freshly cut. But when it is dried, it becomes very hard. So it holds its shape and can support people.

Reporter: (14)_________

JF: Sometimes I get the wood by cutting young branches from trees. This actually helps keep the trees healthy. Other times, I collect wood from the forest floor.

Reporter: (15)_________

JF: You have to be able to draw and use different artistic mediums (媒介). And you also have to know how to speak to people — your customers and the people who work with you.
