made sb do sth 与sb is make to do sth 有什么不同?哪个是主补,那个是宾补.

一句是对的,二句是错的就那么简单

前面那个是主动，后面那个表示被动关系
像这样的词还有很多像：see and so on

made sb. do sth. 要显示主语,谁要谁做事
sb. is made to do sth 强调了做事的人,但不显示谁让他去做.
e.g.
His girlfriend made him buy the Ipod.
He was made to buy the Ipod.
(第一句透露 “女朋友”叫他买Ipod.,第二句避开了.）
made sb do sth 是宾补.
sb. is made to do sth 是主补
