频度副词 语法详解+专项练习 语法详解 （一）频度副词的定义 频度副词是用来表示动作发生频率的副词，外研版七上Unit 4围绕“节日庆祝、日常习俗”展开，频度副词是描述节日活动频率、日常行为习惯的核心词汇，如usually（通常）、often（经常）、sometimes（有时）。 （二）常见频度副词及频率等级 频度副词按频率从高到低可分为以下几类，七年级上册需掌握核心常用词的含义与用法： 频度副词 含义 频率等级 always 总是，一直 100% usually 通常 80% often 经常 60% sometimes 有时 40% seldom 很少 20% never 从不 0% （三）频度副词的位置 频度副词在句中的位置有固定规则，这是七年级上册的核心考点： 放在be动词之后 例：She is always late for school.（她上学总是迟到）；They are usually happy at Spring Festival.（他们春节通常很开心）。 放在实义动词之前 例：I often visit my grandparents at weekends.（我周末经常看望祖父母）；He sometimes eats dumplings for breakfast.（他有时早餐吃水饺）。 放在助动词/情态动词之后，实义动词之前 例：We will never forget the Spring Festival.（我们永远不会忘记这个春节）；She can always finish her homework on time.（她总能按时完成作业）。 特殊情况 sometimes可置于句首、句中或句末，置于句首时常用逗号隔开：Sometimes, I go to the park with my family.（有时，我和家人去公园）。 often也可置于句末，需加very等修饰：He plays basketball very often.（他经常打篮球）。 （四）频度副词的用法 描述日常行为或节日习俗的频率 例：We usually celebrate Christmas with our family.（我们通常和家人一起庆祝圣诞节）；She seldom eats fast food.（她很少吃快餐）。 回答关于频率的提问 用How often提问动作发生的频率，回答时直接用频度副词或加具体时间。 例：—How often do you go to the cinema （你多久去一次电影院？）—Sometimes. / I go to the cinema sometimes. 与一般现在时连用 频度副词常和一般现在时搭配，因为二者都用于描述经常性、习惯性的动作。 例：He always gets up early in the morning.（他早上总是早起）；They never watch TV on school days.（他们上学日从不看电视）。 （五）高频易错点 频度副词位置错误 错误：I am often late.（正确，be动词后）→ 误写为I often am late.；He plays usually football.（正确：He usually plays football.，实义动词前）。 sometimes的拼写错误 错误：sometime（意为“某个时候”，非频度副词）、some times（意为“几次”）与sometimes混淆。 频度副词与时态搭配错误 错误：He is always go to school by bike.（频度副词与一般现在时连用，应为He always goes to school by bike.）。 How often提问的回答错误 错误：用How many times（问次数）或How long（问时长）的答语回应How often，如回答“Three times”而非“Sometimes”。 专项练习 （一）根据频率等级，将下列频度副词按从高到低排序 always, never, often, usually, sometimes, seldom → _____ （二）用适当的频度副词填空 I _____ celebrate Spring Festival with my grandparents.
