  托福阅读词汇题:feat

  【Paragraph 2】A warm-blooded turtle may seem to be a contradiction in terms. Nonetheless, an adult leatherback can maintain a body temperature of between 25 and 26°C (77-79°F) in seawater that is only 8°C (46.4°F). Accomplishing this feat requires adaptations both to generate heat in the turtle’s body and to keep it from escaping  into the surrounding waters. Leatherbacks apparently do not generate internal heat the way we do, or the way birds  do, as a by-product of cellular metabolism. A leatherback may be able to pick up some body heat by basking at the  surface; its dark, almost black body color may help it to absorb solar radiation. However, most of its internal heat  comes from the action of its muscles.(A Warm-Blooded Turtle)
