问题 You __________ all those calculations! We have a computer to do that sort of thing.

选项 A.needn't have done B.must not have done C.shouldn' t have done D.can not have done

答案 A

解析考查情态动词。needn’thave done sth．意为“本不必做某事，但实际上做了”，没有must nothave done sth．这种否定推测的表达方式，shouldn’t have done sth．意为“不该做某事但做了”，can not have donesth．意为“不可能做某事”，句意为“你本不必做那些计算，那些事情可由我们的电脑来做”。故选A。

错误信息

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
