1. 概念 : 频度副词是用来表示动作发生频率的词，常用来表示不确定时间，主要包括always, usually, often, sometimes, hardly ever, seldom, never等。
always 意为“总是，永远”，表示频度最高。
usually 意为“通常”，即很少有例外，多用于一般现在时。
often 意为“经常”，在频度上不如usually那么频繁。
sometimes 意为“有时，偶尔”。
hardly ever 意为“几乎不，很少 ”，表示否定意义。
never 意为“从来没有，绝不”，表示否定意义。
以上几个频度副词所表示的频度，从低到高为：
never
0%
hardly ever
5%
sometimes
30%
often
60%
usually
80%
always
