一、词语用法：
v.(动词)
1、decline用作动词的基本意思是有礼貌地拒绝邀请、给予或服务。引申可表示“衰落,降低”“倾斜,下降”“下沉”。作“辞谢,谢绝”解时多用作及物动词,其后可接名词、动名词或动词不定式作宾语。作“衰落”解时只用作不及物动词。
2、decline作动词指“有礼貌地谢绝”，比refuse语气上要婉转些；
3、decline后可跟不定式或动名词，但跟不定式比较普遍。
She declined to answer my questions.
4、decline的名词形式有declination，declinature和declinal，但都不常见。美语中declination比较常见，但还是习惯用refuse的名词形式refusal。
二、词汇搭配：
1、decline westward向西下沉
2、decline courteously〔tactfully〕有礼貌〔巧妙〕地谢绝
3、decline drastically急剧下降
4、decline gradually渐渐下落
5、decline notably〔steadily〕显著〔略有〕下降
