修改原因
修改前After the protests, the council refused from its plan to raise bus fares.
修改后After the protests, the council backed off from its plan to raise bus fares.
Refuse 不与 from 搭配：可以说 refuse an offer 或 refuse to help。议会或公司迫于压力放弃计划时，back off from 很合适。因此修改把 refused from 换成 backed off from，保留其余部分。
Back down 意思相近，但侧重在争执中让步、放弃原先立场：After a week of complaints, the landlord backed down and fixed the heating。Back off 不一定涉及争论：可以从发怒的狗旁边退开、不再干涉别人的生活，也可以悄悄放弃计划。
