Besides the little girl who brought up the rear, the herd was preceded by a boy about fourteen, whose duty it was not to let the foremost, the most enterprising, or, in other words, the most empty pig, advance too fast.
译文:除了这个负责把后面的猪赶上来的小姑娘之外,还有一个在前面带路、大约十四岁的男孩。他的职责是不让那些跑在最前面的、最大胆的,或者换句话说,最漫无目的猪走得太快。
曹老师好!
弟子请教曹老师,从句中标出的it是否多余,为什么?谢谢曹老师。
