帮忙翻译一篇课文，谢拉

Have you ever seen a horse with toes?Millions of years ago,horses had many toes.They had four toes on each front foot.They had there toes on each back foot.
These small horses lived in the forsts.And toes helped them run over the soft,wet ground.
It was once very hot in the forests.But the weather changed later.It become cold.Many trees could not live in such weather,so they died and fell down .Open fields took the place of forests.The sun made the ground dry and hard.
Horses began to get bigger with climate changing.On the dry,hard land,horses needed only their middle toes for running.Their middle toes became hard.After a long time,horses had one hard toe on each foot.We call it”hoof”.

你是否看过马有多个脚趾？几百万年以前的马是有较多脚趾：每个前脚4个而后脚是三个。这种马体型矮小，生活在丛林中，而这样的脚趾可以让它们在松软、潮湿的地方奔走自如。丛林地带原来湿热，后来气候变化导致大量树木死亡，原来的丛林地带出现了大片的空地。这些空地在太阳的照射下变得干燥而坚硬，于是马为了适应这种变化也变得高大起来。在这样干燥、坚硬的土地上，马奔跑仅需一个中趾就成，所以他们的中趾也逐渐开始演化，天长日久马就进化成只有一个强健的中趾，即所称的“马蹄”。
