    The zebra belongs to the horse family.One of nature's great mysteries is why the zebra has stripes.One

theory is that the stripes help the zebra cool down.On hot days the black stripes get a lot hotter than the

white area of the zebra and under the black stripes there are special layers of fat for protection.Hot air then rises off the black stripes,forcing colder air down around the white areas,cooling the zebra down.This,

however,is just a theory.The stripes can also confuse predators (食肉动物) when zebras stay with other

animals in great numbers.

     Zebras have excellent hearing and eyesight and can run at a speed of up to 35 miles per hour (56

kilometers per hour)．They also have a powerful kick that can cause serious injury to a predator,like a

lion,or an African wild dog.Usually the lead male of the herd stays at the back of the group to defend

against predators if necessary,while the females and youngsters run from danger.

     Zebras are herbivores and feed mostly on grasses,although they also might eat the leaves and stems (茎) of bushes a bit.They eat grasses for many hours each day,using their strong teeth.Spending so much

time chewing wears the zebra's teeth down,so their teeth keep growing all their lives.As the dry season

arrives and the grasses die back,zebra herds travel to find more food and water holes for drinking.Most

zebras have no specific territories.They travel from place to place,never staying in one area very long.
