如果你丢失的话，我的孩子们经常丢书，你必须买一本新的还给图书馆。

And if you don't, you'll pay the penalty and if you lose it, which my children do sometimes, you have to replace it and buy them a new book or video.

她的书就是你丢的那本。

She has the same book that you lost.

That won't mean at the end of the course of 1504 or 100 or 100 other courses in the workshop and sold the books that you read, it's not that you will not have painful emotions anymore.

那并不代表在1504课程结束后0,或修读完另外100门课程,然后就可以把读过的书丢了，并不是说，你就不会再感受到痛苦的情绪。
