问题 Each pair of penguins lives together with ______.
According to the passage, Emperor penguins fight against each other for ______.

选项 A、a piece of ground
B、a female
C、an egg
D、a chick left alone by its parents

答案D

解析 根据短文最后一段中Emperor penguins never fight—unless a penguin leaves a chick for a minute.Then they fight because they all want it.可知他们为受到遗弃的chick而打斗。易误选[A],只有在经过一块土地而没有请求许可的情况下,才会打斗,而不是为了土地就打斗。
