用什么样的方式学习频度副词效果回很好呢？再请用as often as not 造个句子

可以按发生的频率排序：
never: 从不
He is never late for work. 他上班从不迟到。

scarecly/hardly/rarely: 几乎不
He is scarely/hardly/rarely late for work. 他上班几乎不迟到。

seldom: 很少
He is seldom late for work. 他上班很少迟到。

occasionally: 偶尔
He is occasionally late for work. 他上班偶尔迟到。

sometimes: 有时
He is sometimes late for work. 他上班有时迟到。

often: 经常
He is often late for work. 他上班经常迟到。

frequently: 频繁地
He is frequently late for work. 他上班频繁地迟到。

usually: 通常
He is usually late for work. 他上班通常迟到。

almost/ nearly : 几乎
He is almost late for work. 他上班几乎要迟到。（这里almost/nearly 似乎不是表频率，表示差点要迟到。）

always: 总是
He is always late for work. 他上班总是迟到。

forever: 永远
He is forever late for work . 他上班没有一天不迟到。

as often as not: 通常，过半。 和 more often than not 意思差不多。
When it rains , he is late for work as often
