Before I tell you about the interesting discovery related to Tyrannosaurus rex, I need to review something we studied last semester—the difference between what are commonly called cold-blooded and warm-blooded animals. In warm-blooded animals, birds and mammals, for example, the body temperature normally stays within a narrow range, no matter what the outside temperature is. As a result, a warm-blooded animal is usually active in both cold and hot weather because its body temperature can adjust to the temperature of its environment.
On the other hand, cold-blooded animals, such as most reptiles, amphibians, and insects, are unable to create enough heat internally to raise their temperature above the temperature of the environment. So, for example, the temperature of a cold-blooded animal falls when the environment is cool.
I hope this distinction is clear. Now, moving on to Tyrannosaurus rex, you may know that dinosaurs, being reptiles, are generally believed to have been cold-blooded. Well, a recent research study found that the chemical composition of the bones of Tyrannosaurus rex was consistent with the bones of an animal that has a very narrow range of internal temperature, indication that it was probably warm-blooded.
6. What is the main topic of the lecture?
7. What is likely to happen to cold-blooded animals when the weather is cold?
8. Why does the speaker discuss Tyrannosaurus rex?
选项
A、It was larger than other dinosaurs.
B、It was older than originally thought.
C、The composition of its bones confirmed earlier findings.
D、It was probably warm-blooded.
答案
D
解析
Tyrannosaurus rex(暴龙)是一个生僻词,考生虽然很可能不知道它的意思,但是可以根据吾境判断它是一种恐龙(dinosaurs)。事实上,即使考生不知道它是一种恐龙,只要听到了最后一句话“it was probably warm—blooded”,也可以选择出正确答案。
