在英文中用来表示动作频率的词被称为“频度副词”,例如:usually/sometimes/always/等,这些词在程度上有区别。
语法点讲解
always, sometimes, never,
usually,often …
常用频度副词的频率排序:
always 100%
usually 90%
normally 80%
often 70%
sometimes 50%
occasionally 30%
seldom 20%
hardly ever 5%
never 0%
1.频度副词通常放在实意动词之前(1),be动词之后(2),如果句子中出现情态动词或助动词,则放在情态动词、助动词与实意动词之间(3)。
如:
I always do homework in the afternoon.(1)
He is never kind to us.(2)
She can never know your secret.(3)
2.频度副词的特殊位置:表示次数的频度副词,如once, twice,可以放在动词后或句末(4);有的频度副词也可放在句首表示强调(5)。
如:
The car broke down twice.(4)
Sometimes I go fishing with my dad.(5)
1. always 频率最高,表示动作重复、状态继续,表示“一直、总是”,其反义词为never。always等与not连用时,表示部分否定。如:
The rich are not always happy. 有钱的人并不总是快乐的。
Li Ping is always late for school. 李平上学总是迟到。
Li Ping is never late for school.(全部否定)
Li Ping is not always late for school. (部分否定)
频度副词通常和一般现在时连用,表示动作发生的频率。但always与进行时连用时,并不强调动作正在进行,而是表示赞叹、厌烦等情绪。如:
He is always thinking of others. 他总是想着别人。(赞叹)
She is always asking silly questions. 她总是问些愚蠢的问题。(厌烦)
We usually go to school at seven in the morning. 我们通常在早上七点上学。
3. Often意为“经常,时常”,表示反复性的动作或状态,中间有间断,不如usually那么频繁。其反义词是seldom。often在句尾时常被very或quite修饰。如:
It often rains here in April. 这儿四月份常下雨。
The boys often eat noodles and the girls sometimes eat them. 男生经常吃面条,女生有时吃。
I often chat with my friends under the big tree. 我经常在这棵大树下和朋友聊天。
