这是对话类连词成句题，我们可以结合对应学段学过的基础句型规则来组合单词：
1. 第一句是主系表结构，主语为It，后接be动词is，副词really修饰并列的两个形容词clean和beautiful，即可连成通顺符合语境的句子。
2. 第二句是提建议的常用Why not句型，结构为"Why not + 动词原形+其他"，把动词短语clean the garden放在Why not之后，状语together放在句末即可。
3. 第三句是Let's开头的祈使提议句，结构为"Let's + 动词原形+地点/时间状语"，动词为meet，依次排列地点状语at the garden gate、时间状语after class即可。
4. 第四句是一般将来时句子，I'll（I will）后接动词原形bring，再接宾语some rubbish bags就能得到正确语句。
