三、用法
● 一般放在实义动词之前,系动词、第一助动词或情态动词之后,例如:
We usually go to the movies on Sundays.Bethany always runs late for work in the morning.We seldom see her anymore.This class is always a bore!She was never very friendly.I have rarely seen the sun rise.
She will occasionally go for walks alone.
她偶尔会独自去散步。
You can seldom see very far because of the fog.
因为有雾,你看不到很远的地方。
如果有两个助动词,频度副词通常放在第一个助动词后面。如:I will never be an actor!We have never been invited to one of their parties.She must sometimes have wanted to run away.
为了表示强调,频度副词有时也可位于动词 be 态动词之前,例如:
I never was fond of his writing.
我从不喜欢他的写作。
解析:虽然频度副词 never 放在 be 动词之前,但实际上它修饰的还是形容词 fond.You occasionally are a nit-picker.解析:此句中频度副词 occasionally 修饰的是 be 动词。在简略答语中,当频度副词与动词 be、助动词或情态动词位于句末时,频度副词必须前置,例如:----------------------------------------------------------— Can you park your car near the shops?● 有些频度副词如:usually, sometimes, normally, occasionally, often 和 frequently 还可以放在句首或句尾,而且出现在句首时,通常但并不总是以逗号隔开,例如:He travels to Europe frequently.
We’ve been there quite often.
我们经常去那里。
He comes up to visit sometimes.Usually, the work is boring.Occasionally I have to go and ask the boss for a rise.● 除非是为了强调,否则有些频度副词如:always, seldom, rarely, hardly ever 和 never 不出现在句首, 但它们也可以出现在一个句子或是从句的后面,例如:当频度副词放在句首表示强调时,句子的结构就发生变化了,变成部分倒装,例如:Never have I felt so insulted!
Rarely does she leave the house unattended.
她很少会让房子无人看管。
Seldom has there been such a happy meeting.
● 频度副词经常用于一般现在时,用来谈论习惯、一般情况和时间表,但它们也可以用于其他时态,例如:
一般过去时:
She often traveled when she lived in Spain.
她住在西班牙时经常旅行。
现在完成时:
I have never witnessed such a wonder child as he.
我从来没有见过像他那样的神童。
I am always late for work.The trains are occasionally late, but they are generally on time.She is often alone, but I don’t think she minds.
