Sometimes 的用法 　　Sometimes I work in the day and sometimes at night.　　我有时候在白天工作，有时候在晚上工作。　　sometimes是频度副词，表示“有时候”。如：　　Sometimes the little girl laughs，and sometimes she cries．这个小女孩有时笑，有时哭。　　Sometimes I went to school by bike and sometimes on foot．我有时骑自行车上学，有时步行去。　　sometime是副词，表示“曾经，某时，有朝一日”，常同过去时或将来时连用。如：　　Will you go and see your teacher sometime？你哪一天去看看你的老师好吗？　　The accident happened sometime last month．事故发生在上月某一天。　　some time是名词词组，通常表示“一段时间”。　　He rang again after some time．过了一会儿他又打电话来了。　　It will take some time to translate this book．翻译这本书要费一些时间　　常用的频度副词有四个,即always, usually,often,sometimes。　　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：　　She is often late for school. 她上学经常迟到。　　He usually goes to bed at about 12. 他通常(午夜)十二点钟睡觉。　　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：　　I sometimes think that it is a great mistake.我有时想这是一个大错。　　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。　　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：　　I sometimes go to the library.我有时去图书馆。　　Sometimes I read a book in the evening.我有时在晚上看书。　　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。如：　　A great scholar is not always a very wise man.大学者未必一定是极聪明的人。　　We go to the cinema sometimes.(对划线部分提问)　　How often do you go to the cinema?
