與相關詞的區别
warn
vs. warn about
: warn
單獨使用範圍更廣,可以接直接引語 (warned, "Be careful!"
)、不定式 (warned him not to go
) 或 that
從句 (warned that prices would rise
)。而 warn about
則更具體地聚焦于“關于某個特定事物”的警告。warn about
vs. warn of
: 兩者有時可互換,但細微差别在于:warn about
更側重詳細說明風險的性質、細節或如何應對。warn of
更側重宣告風險的存在或即将發生。warned of a storm
(預告有風暴) vs. warned about the dangers of the storm
(警告風暴的具體危險,如強風、洪水)。但這種區别并非絕對。權威參考來源:
“Warn about”是一個動詞短語,由“warn”(警告)和介詞“about”(關于)組成,表示就某事物或情況發出警告或提醒,強調告知潛在的危險、風險或需要注意的問題。
