Spring fever 其实和“发烧”并没有关系。这个表达通常用来形容初春天气突然转暖，人们心里感受到的一种兴奋和躁动感。

例句

The days are getting longer and warmer - I am definitely starting to feel spring fever.

The university library has been very empty lately. I wonder if it's spring fever that's keeping everyone away.

请注意

短语 be full of the joys of spring 借助万象更新的春季来描述一种充满活力的、快乐的感觉。

例句

Sara has been full of the joys of spring all day.

I am full of the joys of spring.
