该短语是 “动词+名词+介词” 结构，后接名词或动名词（v-ing）（因为 of 是介词，需接名词性成分）。
基本结构：
以下从不同场景举例，帮助理解：

（如果你不吃早餐，你可能在午餐前饿肚子。）
She left early to avoid running the risk of missing the train.
（她早走是为了避免错过火车的风险。）
Smoking means you run the risk of developing lung cancer.
（吸烟意味着你有患肺癌的风险。）

If you invest all your money in stocks, you will run the risk of losing everything.
（如果你把所有钱投到股票里，你会冒失去一切的风险。）
take the risk of：与“run the risk of”含义相近，但 take 更强调“主动承担风险”，而 run 更侧重“被动面临风险”。
例：He took the risk of starting his own business.（他主动承担风险创业。）
例：She ran the risk of being late because of traffic.（她因交通问题被动面临迟到风险。）
of 后不能接动词原形：需用动名词（v-ing）或名词。
✖ 错误：run the risk of lose money
✔ 正确：run the risk of losing money
总结：run the risk of 是表达“风险”的高频短语，用于说明“因某行为/情况可能导致负面结果”，后接具体的风险内容（名词/动名词），适用于日常、健康、工作等多种场景。
