假设你是李明，在网上看见一位美国小朋友迈克发帖，说他很想了解中国国宝熊猫，请你根据以下提示给他回帖。 要点如下：
1. 熊猫是世界上最可爱的动物之一，被称作中国“国宝”（national treasure），主要生活在中国四川；
2. 它大约有160cm长，重达120公斤；成年熊猫一天花12个小时吃大约10公斤的竹子；
3．它们每隔两年产一只幼仔。但是这些幼仔经常死于疾病，活不长；
4．由于人们砍伐森林，熊猫没有足够的食物可以吃和足够的地方可以住，已经成为濒危动物；
5. 最后请就如何保护熊猫谈自己的一两点看法；
注意：词数60 --- 80， 书面表达的开头已给出，不计入总词数。
参考词汇：
1. lovely adj. 可爱的 2. weigh v. 重量是…… 3. protect 保护
