occasionally用法与at times有什么区别呢？？？

occasionally 是偶尔的意思，是副词；而at times 是有时的意思，后者频率大于前者。

英语occasionally和accidentally用法上区别是什么？

accidentally "偶尔" 指的是事件的发生不是刻意安排的结果,而是意外的事件,或是"偶然"的事件~

而" occasionally" "偶尔, 间或" 的意思指的是频率上的概念,

我举个例子,你看看,也许就明白了:

1. I met her accidentally yesterday. 我昨天在无意中遇到她.(或, 我昨天很意外地遇见了她.)

2. My friends visit me occasionally. 我的朋友偶尔会来拜访我.

偶然 一词用英语怎么说

1. occasionally

2. occasional

3. incidentally
