问题 Li Lei didn’t meet the famous American professor_____ he was on holiday in America last year.

选项 A、unless
B、until
C、if
D、whether

答案B

解析本题考查的是由not…until引导的时间状语从句，表示“直到……才”，故B项为正确答案。又如：Ididn’t sleep until my mother got home．(直到妈妈回到家，我才入睡。)如果放于句首，句子要倒装，如：Not until mid-night did his father stop working．(直到午夜他父亲才停止工作。)
