用法辨析

v. (動詞)

• decline用作動詞的基本意思是有禮貌地拒絕邀請、給予或服務。引申可表示“衰落,降低”“傾斜,下降”“下沉”。作“辤謝,謝絕”解時多用作及物動詞,其後可接名詞、動名詞或動詞不定式作賓語。作“衰落”解時衹用作不及物動詞。
• decline作動詞指“有禮貌地謝絕”，比refuse語氣上要婉轉些；
• decline後可跟不定式或動名詞，但跟不定式比較普遍。She declined to answer my questions.
• decline的名詞形式有declination，declinature和declinal，但都不常見。美語中declination比較常見，但還是習慣用refuse的名詞形式refusal。
