Question

请问一下这道英语题的D选项和其他选项有什么区别？

C选项是back up

Answer 1

back away 不愿考虑
back out 不遵守(诺言、合同等),改变主意

Answer 2

说实在的这4个答案，其实都可以，主要是看你想表达什么。不过答案D，看似更贴合句子。它们的区别主要在后面的out, off, away，所以要理解它们的核心意思，才能理解这些动词短语。例如：

• The police officers are backed up by extra teams of people at the weekend.

• It's too late to back out now.   停止不做某事

• I think you should back off for a while.   停下来置之不理（并未远离）

• The government has backed away from its nuclear weapons strategy. 停下来（远离）
