用英语描写熊猫的特征：The panda is fat and plump like a bear. Its head is round and its tail is short. Its head and body are 1.2-1.8m long and its tail is 10-12cm long. It weighs 80-120kg, with a maximum weight of 180kg. Its body color is black and white. Its cheeks are round. It has large dark circles under its eyes. It has the iconic walking style of inside eight characters.
It also has sharp claws like a scalpel. The skin of giant pandas is thick, and the thickest part can reach 10mm. The black-and-white appearance is conducive to hiding in dense forest trees and snow covered ground, which is not easy to be found by natural enemies.
翻译：熊猫体型肥硕似熊、丰腴富态，头圆尾短，头躯长1.2-1.8米，尾长10-12厘米。体重80-120千克，最重可达180千克，体色为黑白两色，脸颊圆，有很大的黑眼圈，标志性的内八字的行走方式，也有解剖刀般锋利的爪子。大熊猫皮肤厚，最厚处可达10毫米。黑白相间的外表，有利于隐蔽在密林的树上和积雪的地面而不易被天敌发现。
进化
大熊猫的历史可谓源远流长。迄今所发现的最古老大熊猫成员——始熊猫的化石出土于中国云南禄丰和元谋两地，地质年代约为800万年前中新世晚期。在长期严酷的生存竞争和自然选择中，和它们同时代的很多动物都已灭绝，但大熊猫却是强者，处于优势，生存至今成为“活化石”。
