题目

请问spread out的用法.
一般词典的例句是主动式,但我在原文英文书里看到这句话：
His giant wings were spread out on either side of him.
那是否可用主动式呢?
词典的例句，例如：He spread out his arms and shrugged his shoulders.
类似的主语却使用主动式！

答案

spread out 这个词组可灵活用于主被动句
be spread out:e.g.Papers are spread out on the table.
或 sb spread out sth:e.g.Let's spread our papers out on the table.
另外,spread这个词过去式与过去分词同形,都是spread.
