帮我翻译一下,急!
Have you ever seen a horse with toes?Millions of years ago ,house had many toes.They had four toes on each front foot.They had three toes on each back foot.The hourses were no bigber than cats.
These small horses lived in the forest.Their many toes helped the horses run over the soft,wet ground.
It was very hot in the forest.But the weather changed.It became cold.Many trees could not live in cold weather.The trees died and fell.Open fields took the place of foresls.The sun made ground dry and hard.
Horses began to change,too.They began to get bigger.This took a long time.On the dry,hard land,horses needed only their middle toes for running.Their middle toes became hard.After a long while,horses had only one hard toe on each foot.We call this hard toe a hoof.

你听说过马有脚趾么?几百万年已前,马是有趾的.它的前脚有4个脚趾,后脚是有3个脚趾.那时侯的马个子不比猫大多少.
这些小型的马生活在森林里它们的脚趾帮助这些马轻松的奔跑在轻软,湿润的土地上.
森林里的温度是很热的.不过温度是一直变化的.气温变冷了.许多树不能生活在阴冷的气候里.所以这些树都死掉了.于是森林空出许多平地.太阳的照射使这些地面变的又干又硬.
马也跟着进化了.他们的体形也变大了.这花费了很长的时间.在又干又硬的地方上,马奔跑的时候只需要它们脚的中趾.他们的中趾变的更厚实了.经过一段时间的进化,马的每个脚上只有一个脚趾了.我们称这个脚趾为蹄.
