没学语法觉得这两个短语挺正常的啊！go buy：去买，come visit：来访！学了语法以后懵了，动词不能连用？这两个短语语法错误？
原来go buy = go and buy, come visit = come and visit。可能太经常使用的缘故，习惯简介的英语把and省略了。
I'm going to go buy some bread.
Go and buy some fruit at the fruit market.
He must also come visit her in Shanghai at least once a month.
Come and visit us if you're ever in our part of the world.
