Answer 1

所以会混淆,是因为两者都有残余、剩余的意思,但是,做“残余、剩余”的名词解时：
leftover一般指吃剩的饭菜,作残留物也指具体的事物,如：
Substances such as urea (a leftover from protein metabolism) and excess phosphate ions therefore flow from the blood to the water.
类似于尿素（蛋白质新陈代谢的副产品）和多余的磷酸盐就从血液流进了水里.
remains主要是遗体、尸体、残骸.引申为残留物时常指抽象的事物,如：
He also argued that much remains unknown about the interaction between Arctic sea ice,sea level,and temperature rise.
他还认为,有关北极海冰、海平面图和气温上升之间的相互作用还存在许多未知数.
