在英语中,可以用 "The air in the countryside is fresh and clean" 来表示农村的空气好。

这个表达式的来源可能是因为农村地区通常没有城市那么多的汽车和工厂,所以空气会比较新鲜和干净。

下面是一些英文例句和它们的中文翻译:

"I love pving in the countryside because the air is so much fresher than in the city." (我喜欢住在农村,因为农村的空气比城市新鲜得多。)
"I always feel more energized and healthy when I visit my grandparents in the countryside, and I think it's because of the clean air." (我每次去农村看望我的爷爷奶奶时总感觉精力充沛和健康,我想这是因为那里的空气干净。)
"The air in the countryside is so pure and refreshing, it's pke a breath of fresh air." (农村的空气那么纯净和清新,就像一口新鲜空气。)
