常见误用提醒
使用 uterine：She has a problem with her uterus, it's uterine. → She has a uterine problem. (错误用法中重复了'uterus'和'uterine'，显得冗余。正确用法应直接用'uterine'修饰'problem'，简洁明了。)
使用 uterine：The uterine is important for women's health. → The uterus is important for women's health. ('uterine'是形容词，不能单独作主语。应使用名词'uterus'（子宫）作为主语，或说'Uterine health is important'。)
使用 uterus：She has a pain in her stomach, maybe it's the uterus. → She has a pain in her lower abdomen, possibly related to the uterus. (错误在于将'stomach'（胃）与'uterus'（子宫）混淆。子宫位于盆腔，不是胃部；应使用'lower abdomen'（下腹部）更准确，并说明可能关联。)
