程明

这些都是为将来能有个好工作，好生活而打拼，程明说。

" It ` s all about working for a better future with a better job ," Cheng said .

老师随机检查出席率时，每当点到程明的名字，替身就会提他喊到。

When the teacher randomly checks the attendance , the double is there to say " present !" when Cheng ` s name is called .

这名替身还会把课上提到的重点整理成笔记，这样一来甚至比我自己去上课还要好，程明解释说。

The double also marks the key points mentioned in class , so it ` s " even better than if I attend the lecture myself ," Cheng explains .

程明认为有些选修课真的很“鸡肋”&你必须去上课但它们对未来几乎没有用处，于是他决定试一试这个方法。

Cheng was thinking that some electives were just " chicken ribs "– you have to take them but they 're hardly useful for the future – so he decided to give this method a shot .

22岁的华东理工大学大三学生程明在校内论坛（电子公告牌系统）上看到了一则广告，发帖人宣称自己可以帮别人代课，每节课收取15元。

Cheng Ming , 22 , a junior at East China University of Science and Technology , saw an ad on the BBS ( bulletin board system ), where someone offered to attend class for others for 15 yuan per class .
