at 大老鼠 mouse 老鼠
RAT 在字典里的解释是an animal that looks like a large mouse with a long tail（一般超过12厘米）
生活中一般说到rat是贬义,经常形容“不忠的人”
mouse就是一般的小老鼠
为什么说家外的是RAT 家里的是mouse,也不是没有根据的,因为rat一般就是野外的那种褐鼠和黑鼠
Mouse长着又长又细的尾巴,小小的,又叫“耗子”；Rat的尾巴稍比mouse的短,但它们比mouse大,又叫“大鼠”.人们常用mouse表示胆小怕羞的人；而言而无信的人常被比喻为rat.Mouse常出现在房子(house)和田野(field)里；rat通常出现在房子里.
rat含贬义,就象国内的过街老鼠,肮脏,是害虫.
mouse不含褒贬之意,外国人看mouse是一种动物,一般都是指实验室里的小白老鼠.
