Which book do you have to buy?

If I am a teacher, I will buy this book (Your Turn Best 3). Because I think this book is very interesting and there are a lot of colorful pictures in the book. To make the student pay attention more when they open the book especially, contents of this book are emphasized learning by using Inductive approach. Through, the student will be taught from example to rule for knowing the sentence first. After that, they will do exercise and may listen to the tape following the passage. Then, they will do by themselves and finally end up developing some general conclusions by the rule. These are to make the student understand the grammar using and use it correctly and also they can apply the rule by themeselves.
