Dear Mandy,
I’m very happy to hear what you are enjoying reading books. There are many reason for my recommendation. First, dividing by subject area-science, geography and history — and written in an interesting way, you will find the book valuable and practice . What’s more, to make it more vivid and easy to understand, each page is accompanied by a colored picture to show more details. In addition, when you came across new words, you can learn from them by Pinyin in the book, which I think is great use to you.
I have finished reading the book and it is really worth read it again. I sincere hope that you will like this book and get a lot of interesting information from it .
Yours ,
Li Hua
