题目内容
19.They sent the children a lot of presents on Children's Day.(改为被动语态)A lot of presentswere sentto the children on Children's Day.
分析 儿童节那天他们给孩子们送来很多礼物.
许多礼物在儿童节那天被送给孩子们.
解答 答案:were sent.原句中sent是send的过去式,下文的主语a lot of presents是动词send的承受者,构成被动关系,结合时态用一般过去时的被动语态was/were+过去分词,send的过去分词sent,主语是复数,故were,故答案是were sent.
点评 一般过去时的被动语态was/were+过去分词的呈现,各种类型的被动语态的构成要理解掌握.
