the study found that children who spend more time outdoors have a lower risk of myopia, and the protective effect increases with the duration of outdoor activities. the reason may be that natural light can promote the secretion of dopamine in the retina, which inhibits the elongation of the eye axis. eye axis elongation is a key factor in the development of myopia. therefore, to prevent myopia, children should be encouraged to spend more time outdoors.
explanation:
- first blank: "inhibits" is appropriate because dopamine (stimulated by natural light) reduces or prevents the elongation of the eye axis—this directly links to the lower risk of myopia mentioned earlier.
- second blank: "spend" fits naturally in the phrase "spend more time outdoors," which is the core recommendation for preventing myopia based on the study.
both words align with the logical flow and scientific context of the text.
answers: inhibits; spend
