|
答案
| D |
解析
| ...until...是“直到”的意思,表示某一种行为一直持续到某一时间；...not...until是“直到...才”表示直到某一时间,某一行为才发生,而在之前该行为并没有发生.如: I studied English until 9 o’clock last night. 我咋晚学英语一直学到9点钟(表示9点前一直在学) 。I did not study Englis until 9 o’clock last night. 我咋晚直到9点钟才学英语(表示9点才开始学)；needn’t:不必；can’t:不能。根据句意，应是“你不能离开，直到铃响才能离开”故选D。 |
