volunteering at a summer camp is not an easy task,especially when you aree not being paid to do it.
at the end of the camp i find it so hard to say goodbye because these ar peeople i admire so much ,who ar always giving and never complaining or seeking anything in return.
后面为什么用逗号?前面i admire so much 也是个定语从句修饰PEOPLE啊,后面又是一句who引导的定语从句,用连词连接吗?
既然是两个定语从句，都修饰PEOPLE 为什么不永连词并列两个从句
