题型描述: 段落翻译The air that sweeps the South Sea Islands is fragrant with flowers and spice. Bright warm days follow clear cool nights, and the rolling swells break in a never-ending roar on the shores. Overhead the slender coconut palms whisper their drowsy song. When white men first came to the Pacific islands, they found that the people living there were like happy children. They were tall men and beautiful women who seemed not to have a care in the world. Coconut palms and breadfruit trees grew at the doors of their huts. The ocean was filled with turtles and fish, ready for the net. The islanders had little need for clothing. There was almost no disease. Cruel and bloody wars sometimes broke out between neighboring tribes, and canoe raids were sometimes made on nearby islands. The strong warriors enjoyed fighting. Many of the islanders were cannibals, who cooked and ate the enemies they killed. This was part of their law and religion. These savages, however, were usually friendly, courteous, and hospitable. Some of the early explorers were so fascinated with the Pacific islands that they never returned to their own countries. They preferred to stay.英汉翻译
