问题 Where do you think is the passage from?
Which of the following is not the features of mammals that distinguish them from the reptiles?

选项 A、They’re warm-blooded.
B、They have a set of teeth of different shapes.
C、The first period of development of young mammals is within their mother’s body.
D、There’s some association between mother and infant.

答案D

解析 细节理解题。A,B,C三项在文章第一段有明显对应的句子,至于D,文中原句是“The enforced association between mother and infant provides an opportunity for learning that does not exist for those kinds of creatures that are hatched from eggs long after their parents have departed from the scene.”选项与原文意思有出入。
