　　托福口语Task6话题：动物的一夫一妻制

　　主要讲述了有些动物一夫一妻制的原因

　　1.自身条件限制。例如：海马生存在海洋里，不是天生的游泳高手，而且数量少 sparse，分布得散，它们很难找到配偶。

　　2.繁殖频率低(low reproduction rate)，为了下一代的 survive。例如： albatross 鸟一年只产一个蛋，父母可以一个来照顾幼鸟，一个去找食物，保证幼鸟的存活率。

　　参考范文：

　　In the animal’s world, having many mates can ensure the survival of the species, but there are some exceptions. In the lecture, the professor talks about 2 vivid examples to introduce 2 reasons why some animals just have one mate.

　　Hard to find a mate is definitely one reason. For example, seahorse, an undersea creature lives sparsely. Such living habit imposes seahorses a disadvantage to find a mate. And that compounds the physical limitation of seahorses themselves, that they are not good swimmers, which again sets a great limitation for them to find a mate.

　　The low reproduction rate can also be a reason. For example a kind of birds called albatross just lay one egg a year. In order to ensure the survival of the bridling, one of the parent bird needs to take care of it while the other should search for food.
