为什么这个句子用until不用when 并翻译until recently,Anna worked as a teach (18:6) ----(Until/When) recently,Anna worked as a teacher in until recently until recently后面的接个句子用什么时态,为什么? while,when,until,after,before,as soon as 怎么用? 用when,while,as soon as,until,before,after填空 用as soon as,when,not until造句,急! 英语翻译为什么用until 而不用when,或since,或after 请用“until”和“not until”各造一个句子,并翻译.（简单易懂就行了） as、while、which、until、after、that和when在什么时候用,为什么?它们有什么区别? Until fairly recently 关于until just recently~
