二、位置
频率副词在句中通常位于情态动词和be动词之后、行为动词之前。如：

我经常见她步行去学校。
She can always get good grades in exams.
她总是能在考试中取得好成绩。
He is hardly ever late for work.
他上班几乎不迟到。
三、用法
1. always意为“总是，一直”，这是频率最高的词，表示动作反复，状态持续，不间断。其反义词是never，意为“从不”。如果要变为否定句，应将always改为never才能全部否定。另外，当always与进行时态连用时，常表示“总是”，带有厌烦、不满或赞美等感彩。如：
Li Ping is always late for school.
李平上学总是迟到。
Li Ping is never late for school.
李平上学从不迟到。（全部否定）
Li Ping is not always late for school.
李平上学不总是迟到。（部分否定）

这个小男孩总是要钱。（表厌烦）
2. hardly ever意为“很少，几乎不”，表示否定意义。如：
The little girl hardly ever goes out.
这个小女孩很少外出。
He hardly ever gives his wife a present, does he
他不常给妻子送礼物，是吗？
6. never意为“从来不，从来没有”，也表示否定意义，它表示从未发生的动作或情况，没有例外。如：
The boys never eat chocolate and the girls seldom eat it.
男生从不吃巧克力，女生很少吃。
Better late than never. [谚语]
迟到（迟做）总比不来（不做）好。
