新概念三-Lesson-1-A-puma-at-课件1pumapuma2美洲狮：一种栖息于北美洲、中美洲、甚至南美洲的食肉目猫科动物，又有称山狮、墨西哥狮、银虎、佛罗里达豹，雄性体重可达250磅。美洲狮分类上属美洲金猫属。美洲狮在跳跃方面有着惊人的“天赋”，它轻轻一跳，便能跳到6—7米以外，更厉害的一跃可达40英呎，高达13英呎。美洲狮是一种凶猛的食肉猛兽，也是噬杀成性的“杂食家”，主要以野生动物兔、羊、鹿为食，在饥饿时也会盗食家畜家禽。如果美洲狮捕捉的猎物比较多，它们就会把剩余的食物藏在树上，等以后回来再吃。曾有从背后偷袭人类且无挣扎迹象的一击致死纪录，目前在北美某些区域甚至已逐渐与人类生活圈靠近。PumaconcolorMountainLionBACKGROUND美洲狮：一种栖息于北美洲、中美洲、甚至南美洲的食肉目猫科动3新概念三-Lesson-1-A-puma-at-课件4Lesson1ApumaatlargeLesson15TitleAnalysisatlarge:贬：指危险的人或动物，逍遥在外两个窃贼仍逍遥法外
