社区下周将安排一场慈善演出，呼吁居民们主动帮助身边的弱势群体。(call)

The community will arrange a charity show next week, calling on residents to take the initiative to help the vulnerable groups around them.

考查短语、非谓语动词和时态。“社区” 翻译为The community，在句中作主语；“安排一场慈善演出” 翻译为arrange a charity show；“下周” 翻译为next week；“呼吁某人做某事” 用短语call on sb. to do sth.，在句中作伴随状语，所以用现在分词形式；“主动去做事” 用短语take the initiative to do sth.；“帮助身边的弱势群体” 翻译为help the vulnerable groups around them。根据句中时间状语 “next week” 可知，用一般将来时。故翻译为：“The community will arrange a charity show next week, calling on residents to take the initiative to help the vulnerable groups around them.”。
