In Chemistry class, the teacher was explaining the relationship between solvent and solute: "A certain solvent can only dissolve a certain solute. For example, you have eaten a bowl of rice, then one more bowl. After having eaten the third bowl, you have felt full to the throat. At this time, can you eat any more?"

One of the students asked: "Is there any dish?"

化学课上老师讲解溶剂与溶质的关系：“一定的溶剂只能溶解一定的溶质。比如说，你吃了一碗饭，又吃了一碗，第三碗吃下去已经饱了，你还能吃下去吗？”

有个学生问：“还有菜吗？”
