11、looded 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 temperatu
12、re 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-bl
13、ooded 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 Tyr
14、annosaurus 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.

15、r discuss Tyrannosaurus rex? 1 【正确答案】 D 【试题解析】 这道题具有一定的迷惑性，因为四个选项里都包含这段课堂教学讲话里出现过的单词。在这种情况下，首先要确定各个选项的中心词。四个选项的中心词依次是： effects， survive in extreme temperatures， changes in location，differences 这样就比较容易排除 “炎热天气对动物的影响 ”、 “动物怎样在极端气温下生存 ”和 “地点变化对恐龙的影响 ”，从而判断出听力材料的主题是选项 D(冷血动物与热血动物的区别 )。 Tyrannosaurus rex
16、：暴龙。 【知识模块】 短文理解 2 【正确答案】 B 【试题解析】 由于冷血动物不能在体内创造热能，使体温高于周围的环境，在周围环境变冷时，它的体温也会随之下降。因此选 B。根据常识也可以判断出正确答案。 【知识模块】 短文理解 3 【正确答案】 D 【试题解析】 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 warmblooded”，也可以选择出正确答案。 【知识模块】 短文理解 4 【听力原文】 T
