keep their position in a group. Previously it was thought that large individuals simply
used their weight and size to threaten their subordinates and take more of the food for
themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that
understanding the relationships between boss and subordinate animals is important to

The research has proved the fact that voluntary dieting is a habit far from exclusive to humans. “As yet, we lack a complete understanding of how widespread
the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve
health or increase attractiveness, rarely does it improve longterm health and males
regularly prefer females that are fatter than the females' own ideal.”
【语篇解读】 人类节食是为了让自己看起来更加美丽动人,而鱼类节食则是为了避免纷争,避免自己被赶出种群,而最终被吃掉。

A.faces dangerB.has breeding rights
