Astride her web, Charlotte sat moodily eating a horsefly and thinking about the future.

蹲坐在网里的夏洛，正在心事重重地吃着一只马蝇，想着以后的事情。

Horseflies are known to prefer horizontal polarised light.

众所周知马蝇偏向于水平偏振光。

Zebra stripes do, therefore, seem to repel horseflies.

因此，斑马的条纹看起来真的能够防马蝇。

The researchers then recorded videos of horseflies trying to get at the horses.

研究人员随后录制了马蝇试图接近马的视频。

They put these objects in a field infested with horseflies and counted the number of insects they trapped.

他们把这些实验对象放到一个充满马蝇的场地，然后计算被吸引的马蝇数目。

Such research has also shown something odd: horseflies attack black horses in preference to white ones.

相对于白马，马蝇更喜欢叮咬黑马。

The horsefly he's a different sort, he dies of himself.

马蝇他是另一种， 他死于他自己。

But Dr Horvath thinks it might be related to a horsefly's ability to see polarised light, which imposes a sense of horizontal andvertical on an image.

但是Horvath博士认为这可能与马蝇识别偏振光的能力有关，偏振光是从水平和垂直方向打在画面上的。
