351 buy sth. for sb.和mend sth. for sb.结构是否相同
buy sth. for sb. 意为“为某人买某物”，mend sth. for sb. 意为“为某人修补某物”，for sb.都是表示“对象”的，结构相同。make sth. for sb.（为……制造某物）和draw sth. for sb. （为……画某物）也是同类结构。
He bought a pair of shoes for her. 他为她买了一双鞋。
He mended the shoes for her. 他为她修了鞋。
She made a pair of shoes for him. 她为他做了一双鞋。
He will draw a picture for us.他将为我们画一幅画。
提示
但是，buy/make/draw/sth. for sb.可以转换为buy/make/draw/sb.+sth.这种跟双宾语的结构，而mend sth. for sb.则不可。
He bought her a pair of shoes.（正）
He mended her the shoes.（误）
