TPO 30 听力Lecture第2篇 第4题What does the professor imply about crocodiles?为什么答案是A?

What does the professor imply about crocodiles?A. They provide fewer clues about dinosaur nesting behavior than birds do. B. They share many behavioral characteristic with birds like the ostrich and kiwi. C. They have larger clutch volumes than most dinosaurs had. D. The female and the male work together to guard their nest.

Answer 1

Student: Shouldn't the behavior of crocodiles and birds give us some clues then? Professor: Well, with crocodiles, it is the female who guards the nest, and with birds, it depends on the species, it can be the male or the female that takes care the eggs, or both. 学生问：鳄鱼和鸟类的行为能否提供线索? 教授回答：雌性鳄鱼保卫巢穴，鸟的种类不同，情况也不同，可能是一方育雏，也可能父母都育雏，而恐龙可能是雄性育雏。所以它跟恐龙的相似之处没有鸟类跟恐龙的相似之处多。由此推断，教授提到鳄鱼是在暗示鳄鱼能提供的线索比鸟类少，所以选择 A 。
