You'd better go and get your son ____once a month
A to examine

选B么?为什么?

You'd better go and get your son ____once a monthA to examine B examiningC examined D examine 选B么?为什么?
错!应该是C
get 在这里接的是复合宾语,宾语your son 和 examine 检查 之间为被动关系,所以要用examine 的过去分词examined作宾补,表被动
get sth done
全句意为
你最好每个月带你的儿子去检查一次

A (get sb. to do sth.叫某人做某事）

选A
get sb to do sth 让某人做某事 ，是固定搭配。

祝你开心。
