once, one time, at one time的区别

问题描述

感觉 once, one time, at one time 都可以表示“一次”,它们有何区别?

老师答疑

陈老师:

▲强调次数时,用 once。此时不宜用 one time, at one time。如:

—How many time have you been there? 你去过那里多少次?

—Only once. 只去过一次。

She has been beaten only once in six starts. 她参加了六次比赛,只败过一次。

Considering she’d only been there once before, she did well to find the way. 考虑到她以前只到那里去过一次,她路还认得不错。

▲one time 的意思是“曾经有一次”,可与 once 换用。如:

One time we went out fishing on the lake at night. 有一次,我们夜里到湖里去钓龟。

I remember coming home from school one time and finding we’d been burgled. 我记得有一次放学回家发现家给被盜了。

One time I came home two hours late and nobody noticed. 曾经有一次我晚回家两小时,且没人注意到。

▲at one time 的意思是“曾经”“一度”。如:

He was at one time a professor in that university. 他曾一度是那个大学的教授。

At one time  Britain had colonies all over the world. 英国曾在全世界都有殖民地。

He was a great lawyer at one time, but he’s over the hill now. 他曾是一名有名的律师,但是现在不如从前了。

另外,at one time 也可表示“一下子”“一次性”“同时”等。如:

The fish lay thousands of eggs at one time. 这种鱼一次产卵数千个。

My brain can’t hold so much information at one time. 我脑子一下子记不住这么多信息。

Webber had three musicals playing in London at one time. 韦伯有三部音乐剧同时在伦敦上演。

王老师:

同意陈老师的解释。我补充一点关于once 和one time表示次数时, 在表示强调的情况下可以互换的情形。one time 语气更强些。

例如: I have been there only one time. = only once.
