The more books you read, the better your life will be. If you don’t believe me, please consider the following reasons to read more books.

You will have strong brain power .Studies suggest reading makes you smart. Unlike watching television, which requires no thought process（过程）, reading is an active learning experience that will keep your mind sharp (even in old age). 　　
You will travel to a new world .　Sometimes our daily life can start to get boring . At times like this, I like to dive into a good fiction book, where I can forget about whatever problems are stressing me out. I’ll come back refreshed after my mini-vacation to a fresh and exciting place in the world of words. 　　
You will improve your vocabulary .　The more words you’re able to use, the better you will become at expressing your thoughts and feelings. I couldn’t imagine how I would write articles like this if I didn’t actively aim to improve my vocabulary, because using the same few words to express myself would get awfully boring in a hurry. 　
You will entertain yourself at a low price .If you’re looking for entertainment without much money, reading is your best choice. Thanks to the popularity of electronic reading devices(设备), it’s never been easier to entertain yourself for hours at a time, for the low cost of a few dollars.
You will discover surprising new ideas.　　Reading introduced me to concepts （概念）like mindful eating, relaxation exercises, and the importance of loving yourself. If I didn’t read, I wouldn’t realize these ideas. If you don’t read, you will miss many surprising new ideas.　　
You will become an expert（专家） in your field .　Don’t you think reading articles and books by experts in your field might make you better at what you do? If you don’t learn more about your profession, then your lack of passion could be a sign that you’re in the wrong field. 　　
I firmly believe that reading has changed my life . I hope these reasons can encourage you to read more books.
