at a time at times in a time on a time的区别是什么
4个回答

at times:

有时;不时

[例句]

The tide is,at times,very high.

潮水有时涨得很高.

I like Bob but he's very annoying at times.

我喜欢鲍勃,但是他有时也很烦人.

at a time

作“一次,每次”讲,常用于“数词+at a time”的结构中.例如:

Enter two at a time.

每次进来两人.

He checked them off one at a time as they came in.

他们进来时,他一个一个地核对.

注意它与at one time 的区别.at one time一般指“过去某一时期,曾一度(once)”或“同时”的意思.如表示“同时”,则两者可通用.例如:

At one time I used to like her,but not any more.

我曾一度很喜欢他,现在可不喜欢了.

in a time 和on a time 都是在一个时间的意思,另外还有2个短语需要也很重要in time和on time

in time

(1) Before a time limit expires.

及时:在时限到来之前

(2) Within an indefinite time; eventually:

最后,终于:在不定的时间内;最终:

In time they came to accept the harsh facts.

他们最终承认了严酷的事实

on time

(1) According to schedule; punctual or punctually.

按时,准时:按时间表的;准时的(地)
