“乱画”常见的英文表达有 scribble 和 doodle:
scribble:强调随意、潦草地书写或绘画,可能线条不整齐、形状不规则,带有一种快速、不太认真的意味 。例如:He was scribbling on a piece of paper when the teacher came in.(老师进来时,他正在一张纸上乱画。)
doodle:侧重于指在无聊、心不在焉时随意画的简单图画或图案,通常没有什么特定的主题或目的,更像是一种消遣。例如:She often doodles flowers and animals in her notebook during lectures.(她上课时经常在笔记本上乱画花朵和动物。)
