Take turns doing sth造句.初一水平

We take turns looking after the old man
我们轮流照顾这位老人是不是三单,turns都要在末尾加s对么?是否有不加s的情况呢这是个固定句型take turns (in) doing sth不是三单, turn 在这里是名词 如果不在这个结构就不一定如: It is your turn to speakIn?怎么没听说过还能加in的这个结构就是省略了一个in, 要不怎么会是 doing sth 呢?类似的:be busy (in) doing sthspend time (in) doing sthwaste time (in) doing sthhave difficulty (in) doing sth好的,谢谢谢谢采纳
