经常,再三
How often does the train run?
这火车多久一班?
【说明】此词一般用于动词之前,be 和助动词之后,有时也用于句末以加强语气.如:We often go there.We have often been there.We haven't been there very often.
习惯用语
as often as 每当
as often as not (=more often than not) 多次,屡次,往往
every so often 偶尔,有时
once too often 又一次,再一次,次数太多
often and often 屡次三番,经常
问:he often ——(study )at night
答:He often studies at night
能不能换意思相近的 be used to 也是经常的意思
因为后面的study不是第三人称格式,没有加s,而study的第三人称单数是studies。ofter的话,后面动词是单数
答案在上文找
often表示通常
应该填studies 要用第三人称单数
