现在,中学生除了在学习方面投资以外,还有的为健康投资。比如增加一些营养丰富的饮食、健身器材等,但为牙齿健康投资更是值得我们提倡,因为“病从口入”。牙齿很少被我们所重视,除非炎症发作时,我们才会哼出一句:“牙痛不是病,痛起来真要命”。为了避免这种现象的发生,我们就要为牙齿健康投资。 Now, in addition to investing in learning, secondary school students also invest in health. For example, to increase the number of nutrient-rich diet, fitness equipment, etc., but investment in dental health is worth our promotion, because “sick from the mouth.” Teeth rarely get our attention, unless the inflammation occurs, we will hum: “Toothache is not a disease, it tasted terrible.” In order to avoid this phenomenon, we must invest in dental health.
