频度副词是副词的一种,在小学阶段常用的有四个,即always, usually, often, sometimes。现将它们的用法归纳如下:

一、频度副词在句中的位置。

频度副词在句中习惯上位于be动词、助动词之后,行为动词之前。如:

1.She is often late for school.她上学经常迟到。

2.He usually goes to bed at about 12.他通常(午夜)十二点钟睡觉。

3.When do you usually get up in the morning?早上你通常什么时候起床？

sometimes是个特殊的频度副词,既可以放在be动词、助动词之后,行为动词之前,也可以放在句首,还可以放在句尾。如:

1.I sometimes think that it is a great mistake.我有时想这是一个大错。

2.Sometimes I help my mother in the house.有时候我帮助妈妈做家务。

often可以放在句中,也可放在句尾,习惯上不放在句首。如:

We have been there quite often.我们经常到那儿去。

这些频度副词的位置与句中谓语动词有无助动词有关。句中没有助动词时,副词置于动词be之后,其它动词之前。

二、表示频度方面的区别。

always是频度最大的词,意为"总是；永远"。如:

I shall always remember my first day at school.我将永远记住我上学的第一天。

usually意为"通常",即很少例外,频度仅次于always。如:

What do you usually have for breakfast?你通常早餐吃什么？

often意为"经常",在频度上不如usually那么频繁。如:

Li Ping often does his homework in the afternoon.李平经常在下午做作业。

sometimes意为"有时候",频度比often小,表示动作偶尔发生,间断较大。如:

1.I sometimes go to the library.我有时去图书馆。

2.Sometimes I read a book in the evening.我有时在晚上看书。

1.A great scholar is not always a very wise man.大学者未必一定是极聪明的人。

2.We go to the cinema sometimes.(对划线部分提问)

How often do you go to the cinema?
