【正确答案】[参考范文]
Dear Lucy,
I am terribly sorry for not returning the book you lent me last year until now. The reason is that I've been using it all the time, for I found it so helpful to my paper writing that I think I couldn't have accomplished my task without it. Please accept my apologies.
Yours,
Henry

写便条时，根据要求首先要对没有及时还书表示道歉，然后简述没有及时还书的理由，最后再次表示道歉。写作时，注意用词不要太正式，不要用过于复杂的句式，这样更加符合便条的格式要求。
