该选哪项The mother was asked____TV every eveningA.not to let her
8个回答

应该选A.

本题考查的知识点是非谓语动词.题中涉及ask和let两个动词的非谓语动词形式,ask后面接带to的不定式,而let接不带to的不定式.但在被动语态中须把to补加出来.was asked not to 这一被动语态中ask这一动作的承受者"the mother"是let这一动作的实施者,所以被动只与ask有关,而跟let无关,let仍然以主动语态的形式接不带to的不定式.请牢记：

ask sb.to do sth.

ask sb.not to do sth.

let sb.do sth.

let sb.not do sth.

sb.be(am,is,are,was,were) let to do sth.(被动语态)
