与相关词的区别
warn
vs. warn about
: warn
单独使用范围更广,可以接直接引语 (warned, "Be careful!"
)、不定式 (warned him not to go
) 或 that
从句 (warned that prices would rise
)。而 warn about
则更具体地聚焦于“关于某个特定事物”的警告。warn about
vs. warn of
: 两者有时可互换,但细微差别在于:warn about
更侧重详细说明风险的性质、细节或如何应对。warn of
更侧重宣告风险的存在或即将发生。warned of a storm
(预告有风暴) vs. warned about the dangers of the storm
(警告风暴的具体危险,如强风、洪水)。但这种区别并非绝对。权威参考来源:
“Warn about”是一个动词短语,由“warn”(警告)和介词“about”(关于)组成,表示就某事物或情况发出警告或提醒,强调告知潜在的危险、风险或需要注意的问题。
