Question

alway,sometimes,often的区别?及其用法,

Answer 1

always表示的频率为100%,意思是"总是"、"一直"、"始终".它在句子中通常站在行为动词之前,be动词或情态动词之后.如：
I always do my cleaning on Sundays.我总是在星期天搞卫生.
often的频率比always略低些,约为60%-70%,意思是"经常"、"常常".它与usually一样不太安分守己,既可站在行为动词之前,be动词、助动词、情态动词之后,也常跳到句子之前或干脆排在句尾.如：
Do you often write to them?你常给他们写信吗?
Does Fred come here often?弗雷德常来这儿吗?
sometimes的频率比often又低些,约为50%,意思有时、不时.如：
sometimes rich,sometimes poor有时富,有时穷
