I prfer borrowing books from library.Because,in my opinion,we can obtain the knowledge we need by borrowing books from the library just as by buying them.Besides,we can save some money for other use.At the same time,we can only keep the book for a certain period of time,then we wil try to finish the book as far as we can,as a result,we can improve our study efficiency.
这只是一个方面——选择借书.
