几个单词的用法区别?usually often always的用法有什么区别?？

频度副词是副词的一种,在初中阶段常用的有四个,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.

三、频度副词与not连用时,表示部分否定；对频度副词进行提问时,要用how often.,5,1楼的解释很有创意嘛!!!Perfect!,2,同意一楼,2,表示频繁的不同程度：

always 频繁度一百

usually 频繁度 八十

often 频繁度 六十,2,good,1,
