recline 作及物动词时，宾语应是“椅背”“头”等被放倒的东西；表示人自身斜倚时是不及物动词，不加反身代词。加上 himself 是受中文“使自己斜倚”这种过度表达的影响。
Not this

Use this

recline 意为“斜倚、后仰”，decline 意为“婉拒、下降”。拒绝邀请要用 decline，recline 没有“拒绝”的意思。这是拼写相近导致的误用。
Not this

Use this

armchair 是“扶手椅”，人坐在其包围的空间里，应说 in the armchair；on 一般用于斜靠在沙发、长凳等平面上。用 in 才符合“坐在扶手椅里”的语义。

语域：mixed 常见场景：airline/train seat instructions、written descriptions of posture、furniture product descriptions recline 通常偏书面或正式，但 recline the seat 这类用法在乘车、乘机的日常指令中也很常见；口语里更常用 lean back 或 lie back。
recline 读作 /rɪˈklaɪn/，与 line、shine、fine、sign、wine、dine 押韵（均以 /aɪn/ 结尾）。注意不要被拼写误导：engine /ˈɛndʒɪn/、discipline /ˈdɪsəplɪn/、medicine /ˈmɛdɪsɪn/ 虽然含 -ine 或类似拼写，但读音不同。
