原著这一句
She stretched herself up on tiptoe, and peeped over the edge of the mushroom, and her eyes immediately met those of a large blue caterpillar, that was sitting on the top with its arms folded, quietly smoking a long hookah, and taking not the smallest notice of her or of anything else.
她踮起脚尖从蘑菇边缘探头看去，正好对上了一只大蓝毛毛虫的眼睛。它双手交叉胸前坐在蘑菇顶上，静静地抽着一杆长水烟，完全没把她或周围的一切放在眼里。
