Inner Mongolia Children's Publishing House 20 12 The answers to eighth grade Chinese summer homework will be different in different regions. Even in the same city, the summer homework arrangements in different districts and counties will be different, and the versions in different regions are full of tricks. How to answer this question? Guess, maybe no one has given a complete and accurate answer yet. Personally, I think it is not difficult for you to think about such a long summer vacation. I really don't understand. You can ask your classmates or teachers for help.
