By using COCA and BNC,this paper analyzes the collocation of leave5 and finds out that leave5 has an obvious negative semantic prosody. Then,it makes a comparative study on the collocation and semantic prosody of leave5 both in COCA and CLEC,which proves that Chinese learners underuse the negative semantic prosody of leave5 . Finally,three causations of this phenomenon have been explored and suggestions on English teaching and lexicography have been put forward.%运用美国当代英语语料库（ COCA）和英语国家语料库（ BNC）两大语料库，对leave5（ leave的第五个义项）所出现的搭配词进行语义分析发现，leave5具有明显的消极语义韵倾向。用“中间语对比分析”法，通过AntConc3.2.4w软件检索，比较美国当代英语语料库（ COCA）和中国学习者英语语料库（ CLEC）中leave5的搭配词及其语义韵倾向，研究表明，中国学习者使用leave5时多用了积极语义韵，少用了中性和消极语义韵。造成这种差异的原因主要是受母语影响、词语学习深度不足和词典编纂存在缺陷。
