longLong，英语单词，主要作为形容词、副词、名词、动词，作形容词时意为“长的；长时间的；远的；长⾳的；（⼈）⾼的；持续的；冗长的；记得牢的；较⼤量的；远期（获利）的”，作副词时意为“长期地；（某事之前或之后）很久地；（时间名词后）整个时间；远地”，作名词时意为“长时间；长⾳；远期证券；（服装的）长尺⼨；长裤，（美、英、爱）隆（⼈名）”，作动词时意为“渴望，盼望”。

如：He was often late for class.他上课经常迟到。

We often go skating together.我们常常⼀道去溜冰。

You must often come to see us.你要常来看我们。

(2)如果句⼦较短或为了强调，often可以放在句末。

如果句⼦较长或为了强调，often也可以放句⾸。

When I was young, I used to play tennis very often.我年轻时经常打⽹球。

(3)有时often不是⽤于说明句⼦中的动词，⽽是⽤于说明整个句⼦的，此时也通⽤于句⾸。
