As a boy,he was found ___ hard all day long

题目

As a boy,he was found ___ hard all day long
a.made to work b.to make working
c.made working d.making to work
为什么选A?1句中怎么出现了found和made2个动词,其他错在哪?怎么区分和判断

答案

make somebody do something是固定搭配,do用原型
但是如果是被动语态,do就一定要用to do比如,
he was made to kiss the bride
