第一段
1 .Observations of these lizards in the wild have also revealed that their mating habits are quite unusual.
在野外对这些蜥蜴的观察也显示它们的交配习性是非常不寻常的。
2 .Unlike most animals, it seems that they're relatively monogamous,
与大多数动物不同，它们似乎是一夫一妻制，
3 .returning to the same partner year after year.
每年都会回到相同的伴侣那里。
4 .And the male and female also stay together for a long time, both before and after the birth of their young.
而且雌性和雄性也会一起呆很长一段时间，在它们的孩子出生前后。
第二段
1 .It's quite interesting to think about the possible reasons for this.
思考一下（这种情况出现）可能的原因是很有趣的。
2 .It could be that it's to do with protecting their young
可能是为了保护他们的孩子
3 .- you'd expect them to have a much better chance of survival if they have both parents around.
——如果他们的父母都在身边，他们会有更好的生存机会。
4 .But in fact observers have noted that once the babies have hatched out of their eggs,
但事实上，观察者已经注意到，一旦这些婴儿从卵中孵化出来，
5 .they have hardly any contact with their parents.
他们与父母几乎没有任何联系。
6 .So, there's not really any evidence to support that idea.
所以，并没有任何证据支持这个观点。
第三段
1 .Another suggestion's based on the observation that male lizards in monogamous relationships tend to be bigger and stronger than other males.
另一种观点是基于对一夫一妻制关系中的雄性蜥蜴比其他雄性蜥蜴更大更强壮的观察。
2 .So maybe the male lizards stay around so they can give the female lizards protection from other males.
所以雄性蜥蜴可能会留下来保护雌性蜥蜴免受其他雄性蜥蜴的伤害。
3 .But again, we're not really sure.
但同样地，我们也不确定。
第四段
1 .Finally, I'd like to mention another study that involved collecting data by tracking the lizards.
最后，我想提一下另一项通过追踪蜥蜴来收集数据的研究。
2 .I was actually involved in this myself.
我自己也参与其中。
3 .So we caught some lizards in the wild and we developed a tiny GPS system that would allow us to track them,
我们从野外抓了一些蜥蜴，而且开发了一种微型GPS系统能让我们追踪它们，
4 .and we fixed this onto their tails.
我们把GPS系统固定在它们的尾巴上。
5 .Then we set the lizards free again,
然后我们把这些蜥蜴放生，
6 .and we were able to track them for twelve days and gather data,
同时我们对它们进行了长达12天的追踪并收集了数据，
7 .not just about their location,
不仅有它们的位置，
8 .but even about how many steps they took during this period.
甚至在这期间他们走了多少步。
第五段
1 .One surprising thing we discovered from this is that there were far fewer meetings between lizards than we expected
我们从中发现了一件令人惊讶的事情，蜥蜴之间的接触比我们预想的要少得多
2 .- it seems that they were actually trying to avoid one another.
看起来他们实际上是在互相回避。
3 .So why would that be?
为什么会这样呢？
4 .Well, again we have no clear evidence,
我们也没有明确的证据，
5 .but one hypothesis is that male lizards can cause quite serious injuries to one another,
但有一种假说认为雄性蜥蜴会对彼此造成非常严重的伤害，
6 .so maybe this avoidance is a way of preventing this
所以这种回避可能是一种防止这种伤害的方法
7 .-of self-preservation, if you like.
——或者是自保的方式。
8 .But we need to collect a lot more data before we can be sure of any of this.
但是我们需要收集更多的数据才能确定这些。
