Problem: 一个男生本来答应和一个女生一起去上chemistry的复习课，结果临时变卦说他要去书店买一本历史课要用的书。 Solutions: 女生建议他先去买书，然后找她借笔记，不过她的字很乱，看不懂的话再找其他人借。第二种选择是陪她一起上chemistry课，然后明天再去买。男生说明天书可能就买完了，因为这个月初他去问的时候老板就说这本书很抢手，经常供不应求。
The speaker has met a problem that he supposed to have the chemistry review session with his classmate, but he, at the same time, has to buy a book for history class in the book store. There are two solutions for him. Firstly, he can leave for the book and ask his classmate for notes. But her handwriting is so unclear that he may have to borrow notes from others. The second solution is to take the session with her, and buy the book tomorrow. But the book may be sold out tomorrow, as when he booked it at the beginning of the month, the shop keeper told him the book sells well. Compared with the two solutions, I prefer the first one, as the history book is a necessity for his class and he can still borrow notes from whoever takes the review session. (145 words)
