【单选题】1 The Pacific Northwest coast of NorthAmerica is a temperate rain forest, where trees like the red cedar grow straight trunks more than two meters thick at the base and sixty meters high. Western red cedar is often called the canoe cedar because it supplied the native people of the region with the raw material for their seagoing dugout canoes. These extraordinary crafts, as large as twenty meters in length, were fashioned from a single tree trunk and carried as many as forty people on fishing and whaling expeditions into the open ocean.
2 The Haida people from the QueenCharlotte Islands offBritishColumbia were noted for their skill in canoe building.After felling a giant tree with controlled burning, the canoe makers split the log into lengthwise sections with stone wedges. They burned away some of the heartwood, leaving a rough but strong cedar shell. They then carved away wood from the inside, keeping the sections below the waterline thickest and heaviest to help keep the canoe upright in stormy seas. To further enhance the canoe’s stability, they filled the hull with water and heated it to boiling by dropping in hot stones. This rendered the wood temporarily flexible, so the sides of the hull could be forced apart and held with sturdy wooden thwarts, which served as both cross braces and seats. The canoes were often painted with elaborate designs of cultural significance to the tribe.
