阅读材料，然后根据有关内容完成下面的表格。 I started a QQ group named GZ(Guangzhou) English Club two weeks ago. It has 30 members now. We need some more friends who are glad to chat in English. If you are interested in the group and want to be a member of it, please learn and follow these rules. 1. It is an English chat place. Everyone in our group must speak English to communicate with each other. If you speak Chinese, nobody else will chat with you. 2. We often have parties. If there is a party, you’d better come. It’s good for you. You can practice speaking English at the party. And at the same time you can make friends. 3. If you live in Guangzhou, you can join our group. That’s because it is easy for us to enjoy parties. 4. Chatting in English does not mean English is the most important. I think Chinese is our mother language and it is the most important. Wait for you, my dear friends!
