Sean開始在用這一本，我只能說這個系列好的不得了！無法想像！造句的複雜度相當高，很適合英文是母語或接近母語的孩子學習。只是這本書沒有解答，不太適合自修。
My son, Sean (10), has just started using this grammar book. I am so impressed with this series of books - it gets kids writing unbelievably complex sentences.
While such complexity is risky for people who don’t have a firm foundation in English, it is excellent for children who are native or near-native speakers of English.
The only bad thing about this book is that it doesn’t have an answer key, so it’s not very suitable for self-study.
