Please help me understand a couple of lines from the TV show 《家有儿女》#1 I am watching the second episode of the show 《家有儿女》and there are a couple of lines I don't quite understand. Please could you help me. Thank you. Number 1: I do not fully understand these 3 lines: 是第四十八页三到十六行、一道3+x经典理科试题.and 我们班只有夏雪会 The conversation goes like this Mum:那，那她花了多少钱雇你呀 Boy: 别那么庸俗好不好 这不是金钱交易 是第四十八页三到十六行 Dad: 那是什么东西呀 Boy: 一道3+x经典理科试题 我们班只有夏雪会 Mum: 啊，她是让你帮助她 然后她再来帮助你 I get the general idea the mother asks how much the girl has paid for the boy to pretend to be her boyfriend. He says he has not done it for money, he is going to help her and later on she will help him. But what exactly does he mean by those 3 lines？What is I think he is talking about one of the classical Chinese texts, right?
