一道英语选择题“I can not see the blackboard very well ” “perhaps you need ——”A to examine your eyesB to have examined your eyesC having your eyes examinedD to have your eyes examined答案是的D我觉得C也对不是need doing需
正如你所说的 need doing 是需要被做,但是它的主语多是物
【答案】D
【解析】Perhaps you need to have your eyes examined 中 主语 是 you 你,所以用 need to do
另外,后面有个词组时 have sth done 意思是：使某事被做,也表示被动

【另附】 need 的相关用法：
①need to do 需要做某事（主语多是 人）
I need to water the flowers.
②need doing = need to be done （主语多是 物）
The flowers need watering.= The flowers need to be watered.
