【参考范文】

Bigfoot，which was first seen in North America，is one of the worldfamous mysteries.

Witnesses described it as an apelike creature.It was said to be 6－10 feet tall，weighing over 500 pounds and was covered in brown or red fur with large eyes and a big head.Footprints up to 24 inches long have been found.

Teams of scientists and researchers who have gone there to do research have found things related to it，such as waste，fur and so on.However，so far there has been no other evidence to prove its existence.

As far as I am concerned，I think it may be just folk tales or stories to terrify hikers and hunters in North America.
