——考点3：频度副词（always / usually / often / sometimes / never）
本考点源自Unit 7 “Be a Better Learner!”。在描述学习习惯时，我们经常要用到频度副词来表示动作发生的频率。掌握always, usually, often, sometimes, never这五个常用频度副词的含义、位置和用法，对写作和口语表达都很重要。
一、五个频度副词的含义与频率对比
频度副词按频率从高到低排列：
always (总是) → 100%
usually (通常) → 约80%
often (经常) → 约60%
sometimes (有时) → 约30%
never (从不) → 0%
例句：
He always gets up early. (他总是早起。)
She usually takes notes in class. (她通常在课堂上记笔记。)
I often read English in the morning. (我经常早上读英语。)
Sometimes he watches TV after dinner. (他有时晚饭后看电视。)
They never waste water. (他们从不浪费水。)
二、频度副词在句中的位置（重点）
规则： 频度副词通常放在 实义动词之前，be动词、助动词、情态动词之后。
I often go to school by bike. (实义动词前)
She is always kind to others. (be动词后)
You should never give up. (情态动词后)
He has never been to London. (助动词后)
注意： sometimes 可以放在句首、句中或句末。
Sometimes I go to the library. = I sometimes go to the library. = I go to the library sometimes.
三、易错点提醒
易错1： 频度副词与否定句连用时，位置要小心。
He doesn't often go to the cinema. (他通常不去看电影。)
易错2： always 不能与 not 连用表示“不总是”，要用 not always。
He is not always late. (他不总是迟到。)
易错3： never 本身表示否定，不能与 not 连用。
I have never seen him. (不能说 haven't never)
速记口诀：
频度副词记位置，实义动词前，be后情后助后。
always最频繁，never是零蛋。
sometimes可三放，句首句中句末皆可。
