托福TPO/【学术讲座】#59听力原答案解析-音频翻译【新东方在线】

男：请听一则生物学播客上的讲话。

Man: Listen to a talk on a biology podcast.

想象一种比老鼠还小、却和狮子一样有地盘意识的生物。

Picture a creature that's smaller than a mouse, yet as territorial as a lion.

它实际上是真实存在的鲜红巴迪斯鱼，一种淡水鱼。

It's actually the real-life Scarlet Badis, a freshwater fish.

在野外，它通常在印度缓慢流动的溪流中平静地繁衍生息。

In the wild, it generally thrives peacefully in the slow-moving streams of India.

由于它的体型和吸引人的颜色，它也是水族箱和鱼缸里的热门选择。

Because of its size and attractive coloring, it's also a popular choice for aquariums and fish tanks.

然而，在水族馆等圈养环境中，雄性会更加好斗。

However, in captive environments like aquariums, males are more aggressive.

如果其他雄性侵占了它们的领地，它们会追逐并啄咬对方，因此放入大量水生植物至关重要。

They'll chase and nip at other males if they encroach on their territory, so it's crucial to include lots of vegetation.

植物充当了雄鱼领地之间的藏身之处和分界线。

Plants act as hiding places and borderlines between males' territories.

雄性鲜红巴迪斯鱼呈鲜艳的橙红色、猩红色，并带有浅蓝色条纹。

Now male Scarlet Badis are a vivid orangish-red, scarlet with light bluish stripes.

然而，当一条雄鱼在水族箱中没有与另一条雄鱼对峙时，它的猩红色会较暗淡，几乎——但又不完全——类似于雌鱼暗淡的灰色。

When a male isn't having a confrontation with another male in the aquarium though, his scarlet is less bright, it can almost, but not quite, resemble female coloring, which is dull gray.

这可能会让人难以分辨性别，只不过如果你在鱼身上看到任何猩红色，那它就是雄鱼。

This could make it hard to tell the sexes apart, except if you can see any scarlet at all on the fish, it's a male.

此外，与大多数鱼类不同的是，雄鱼通常也比雌鱼稍大一些。

Plus, unlike in most fish species, males are also usually a bit larger than females.

而雄性鲜红巴迪斯鱼展现其最鲜艳颜色的另一个时期是在繁殖季节。

And the other time a male Scarlet Badis shows his brightest coloring is during breeding season.

在水族箱中，可以观察到它跳一种舞蹈来打动雌鱼。

In aquariums, he can be observed doing a sort of dance to impress females.

除了炫耀自己之外，它的舞蹈还包括跟随雌鱼四处游动，直到雌鱼决定是否与它交配。

Showing himself off, his dance also involves following the female around until she decides whether to mate with him.

What does the speaker imply about Scarlet Badis that live instreams?

What point does the speaker make about plants in aquariums?

What can be inferred about female Scarlet Badis?

Man: Listen to a talk on a biology podcast.Picture a creature that's smaller than a mouse, yet as territorial as a lion. Does it sound like a cartoon character? It's actually the real life Scarlet Badis, a freshwater fish. It's only about 2 cm long at most. In the wild,it generally thrives peacefully in the slow moving streams of India. Because of its size and attractive coloring, it's also a popular choice for aquariums and fish tanks. However, in captive environments like aquariums, males are more aggressive. They'll chase and nip at other males if they encroach on their territory, so it's crucial to include lots of vegetation. Plants act as hiding places and borderline between males’ territories. Now male scarlet bodice are a vivid orangish red, scarlet with light bluish stripes. When a male isn't having a confrontation with another male in the aquarium though, his scarlet is less bright, it can almost, but not quite resemble female coloring, which is dull gray. This could make it hard to tell the sexes apart, except if you can see any scarlet at all on the fish, it's a male. Plus, unlike in most fish species, males are also usually a bit larger than females, and the other time a male scarlet badness shows his brightest coloring is during breeding season. In aquariums, he can be observed doing a sort of dance to impress females. Showing himself off, his dance also involves following the female around until she decides whether to mate with him.
