网考网解析：
[听力原文] In what way do whales distinguish themselves from other land mammals [答案解析] 细节题。根据原文中的最后一句话Almost all land mammals, except man, have hair on their bodies to keep them warm, but whales, which have very few hairs, are kept warm by their fat.(除了人以外，几乎所有的陆地哺乳动物都靠身上的毛取暖。而鲸鱼身上几乎没有毛，是靠它们的脂肪取暖。)可知，鲸和其他哺乳动物的区别在于取暖方式不同。选项A同原文的意思一致。B、C、D选项在文章中均有提及，都是鲸鱼与其他哺乳动物的相似之处。答案是A。 [圈定关键词] hairs, bear their young, lungs, hind legs [听前预测] 根据选项中出现的关键词可以推断文章同某种动物有关，因为单词whale的出现，猜测该种动物可能是鲸鱼。同该种动物的特点有关。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
