I recommend this book, because it is very interesting and very easy to understand. This book is about a race between a rabbit and a tortoise. I believe most of the students have heard this story before when they were young. Therefore, it is very easy to understand the plot. When you do not need to worry about the plot, you can pay more attention to the vocabs. Unlike other books, even if there are new words in this book, students can still understand, since they already know the story. It will be really helpful for students to learn more vocabularies.
