where did sam go for his holiday this year!

题目

where did sam go for his holiday this year!
这句话来自新概念第一册第83课,题目是going on holiday,我想问的问题是为什么用go for而不用go on?能用go on his holiday this year吗?

答案

go on holiday和go for one's holiday是两个固定词组,意思是“去休假”.
而Where did Sam go for his holiday this year!的意思是：for his holiday【为了他的假日】,“Sam今年去哪里度假!”.
