繪本簡介

The Great Plains of the United States stretch from the Rocky Mountains in the west to beyond the Missouri River in the east. The Great Plains extend north into Canada and south nearly to Mexico.

Long ago the Great Plains were characterized by gently rolling hills covered with tall grasses.With few trees to block them, strong winds whipped across the Great Plains, blowing hot in the summer and bitterly cold in the winter. It was dry, with rainfall averaging 20 inches (51 cm) a year.

A little over two hundred years ago, in the early 1800s, there were only 150,000 people living in the Great Plains. Most were Native Americans, but there were also European settlers.

美國的大平原從西部的落基山脈一直延伸到東部的密蘇里河之外。 大平原向北延伸至加拿大，向南延伸至墨西哥。 很久以前，大平原的特點是平緩起伏的丘陵長滿高草，幾乎沒有樹木阻擋，大平原上刮起了大風，夏天炎熱，冬天寒冷。 天氣干燥，有 年平均降雨量為 20 英寸(51 厘米)。 兩百多年前，在 1800 年代初期，大平原上只有 150,000 人。 大多數是美洲原住民，但也有歐洲定居者。
