---The teacher said, “Don’t be late, Mary．”---The teacher told ________．A.Mary not to be lateB.Mary to be not lateC.Mary are not latedD.not to be late

A解析直接引语为祈使句，在变间接引语时，主句中的谓语动词往往根据直接引语的口气换用ask(请求)，tell(告诉)，order(命令)，invite(邀请)，warn(警告)，advise(建议)等，而直接引语中的谓语动词要变成动词不等式。即ask/tell/order/invite/warn/advise sb．(not)to do sth．。
