we can buy clothes ,vegetables and toys the most cheaply there.

问题描述:

we can buy clothes ,vegetables and toys the most cheaply there.

不对,应该是:
We can buy the cheapest clothes ,vegetables and toys
cheap的*是the cheapestthe most cheaply 可不可以修饰buycheaply作为副词是可以修饰动词的。但实际上一般都是用cheap来修饰名词的,很少有用cheaply的。从语法角度讲,你的句子没问题,但是从日常应用来说,确实不合适可是英语书上有you can buy clothes the most cheaply there,我只是多加了vegetables和toys语法上是没有问题的,但是日常用语中,大家都是尽量简单的用语交谈,你的虽然语法没任何问题,但是句子太长,而且不常用。
