Foreign Customer Review / 国外客户评价: |
This book has illustrations on each two-page spread with a manageable amount of text for young readers. The best part of the book is that it teaches the concept of theories. It describes 3-4 theories about what happened to the dinosaurs, and explains the theories' weaknesses or gaps in our knowledge |
