易错句子She pecked her lunch, not feeling hungry.
正确表达She pecked at her lunch, not feeling hungry.
当 peck 表示“小口吃、没胃口地吃”时，是不及物动词，必须与介词 at 搭配，即 peck at something；直接用 peck something 意思是“用喙啄某物”，不能用来表达人进食。

易错句子He pecked on her cheek.
正确表达He pecked her on the cheek.
peck 在表示“轻吻”时是及物动词，宾语必须是人，如 peck somebody；“吻的部位”由介词 on 引出，即 peck somebody on the cheek。若写成 peck on her cheek，动词缺少宾语，不符合该动词的用法。
pick /pɪk/ 和 peck /pɛk/ 音近形近。peck 主要指鸟用喙快速啄；pick 多指人用手摘取或挑选。要表示人没胃口、只小口吃时，常用 pick at；若主语是鸟且真的是用喙啄，则用 peck。
peck 读 /pɛk/，是鸟用喙啄；peek 读 /piːk/，是偷偷地看。两个词拼写相近但读音和意思完全不同；表达“偷看”只能用 peek。
peck 的施动者一般是鸟，工具是喙；poke 的施动者多是人，工具是手指、棍棒等尖物。表示“用手指/棍子戳、捅”时用 poke；表示“鸟用喙啄”用 peck。
