【频率副词是什么时态】频率副词是用来表示动作发生频率的副词，如“often”、“always”、“sometimes”、“never”等。它们通常用于描述某事发生的频繁程度，但并不直接表示时态。然而，在实际使用中，频率副词常与特定的时态搭配，以表达动作发生的频率和时间关系。
频率副词本身不表示时态，而是用来修饰动词，说明动作发生的频率。在英语中，频率副词可以出现在各种时态中，但它们的位置和用法会根据时态的不同而有所变化。例如，在一般现在时中，频率副词通常放在动词之前；而在进行时或完成时中，频率副词可能出现在助动词之后。
因此，频率副词不是时态，而是与时态结合使用的一种语法成分。理解频率副词与不同语态之间的关系有助于更准确地表达意思。
