问题 Nancy′ s gone to work but her car′ s still there. She __________ by bus.
选项 A.must have gone B.should have gone C.ought to have gone D.could have gone
答案 A
解析 考查情态动词。句意为“南希已去上班,但她的车还在那儿。她一定是乘了公交车去的”。musthavedone是对过去事情的肯定推测,符合句意。should/ought t ohave done“本应该做某事却没有做”.Couldhave done“本可以做某事却没有做”,显然均不符合题意。

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).
