countryside和country的区别是意思不同、用法不同、侧重点不同。countryside是指与城市相对而言的农村，country作乡村讲时，侧重指区别于城市的乡间、乡下，特别注意的是，country的另一个意思是国家。

例句：I don't really like cities ─ give me the countryside every time.我实在是不喜欢城市，一有机会就让我去乡村吧。He found that life moved slowly in the countryside.他发现乡村的生活节奏慢。It's good to meet people from different parts of the country.结识来自这个国家不同地区的人是有益的。
