Please don’t stand up in class you .
A. until ; are told to
B. when ; are told
C. after ; were told
D. before ; were told to

(答案→)A. until ; are told toB. when ; are toldC. after ; were toldD. before ; were told to解析：句意：在课堂上请到允许你时再站立。Not···until直到……才，是一固定句型；主句使用一般现在时，故时间从句也用一般现在时。Tell sb to do sth告诉某人做某事，改为被动语态后不可丢掉不懂事标记to。所以选A。

收益了
