Question

go for a picnic是什么意思?

Answer 1

go for a picnic在美国英语中是一个习惯用法，而且go for之后还可以跟其他的表示户外活动的名词搭配；go on a picnic这个短语中真正属于习惯用法的是on跟后面表示旅游、露营等外出活动的那个名词的搭配，也就是说picnic不一定非要跟go搭配才能使用，而是可以跟别的词搭配使用也可以，而且这种用法英美两国英语都认同：
1. (American English) go for (a walk, a drive, etc.): to do an activity (such as walking or driving a car) that usually involves going somewhere(美国英语)通常指到某个地方去做某种活动，比如说散步、开车等
