口语中表示刚刚，刚才有这几种说法，根据时间的长短来排序：just now（不确定，亦短亦长，总的来说表示瞬间短的情况比较多）, a few minutes ago（非常短），a short time ago（稍短）, ，a short while ago（短）在英语的口语中，他们用到的频率可以说都是一样的，都是非常常用的口语表达。因为这几个短语中just now的用法比较特殊，那么我现在就来讲一下针对just now的用法：当just now出现在一句口语里面的时候，究竟什么时候表示刚刚呢，就是当谓语动词是过去式的时候比如：I saw him just now. 我刚才看见他了.一看到saw，那么这个just now一定是刚才意思了just now的其他用法：例：Come and see me later, but not just now. 以后再来找我, 现在别来.强调就在此时此刻的意思Business is good just now. 目前生意不错. 目前，现阶段的意思可以通过分析business的好坏是一个过程，所以可以判定这是目前的意思了。所以，"我刚刚出去了"你可以根据你的情况用上面4个短语哪一个都可以I went out just nowI went out a few minutes agoI went out a short time agoI went out a short while ago

1) no sooner... than... ，"一...就..." ，引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句)例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来No sooner ...than...常放在句首,表示强调.这时主句要倒装.例:No sooner had I reached home than it began to rain.2）与这个短语类似的还有hardly ... when 意思为:"还没...就..." (主句用过去完成时,从句用一般过去时)例: We had hardly gotten there when it began to rain. 我们还没到那儿,天就下起雨了.Hardly...when...也常放在句首例: Hardly had we gotten there when it began to rain.3）no sooner than 和hardly when以及as soon as这三个短语都有“一……就”、“刚刚……就”的意思，它们的意思非常相近，因此有时可以互换。例如：“我刚到公共汽车站，汽车就开了。”一句，就可以有如下几句译法：As soon as I got to the bus stop, the bus started.Hardly had I got to the bus stop when the bus started.No sooner had I got to the bus stop than the bus started.4） 但他们之间也有一些差异，例如，如果从两件事情的间隔时间来说，as soon as 较长，no sooner...than 居中，hardly...when 间隔时间最短。其它的一些区别见下面，请大家在运用的时候要留意。a、as soon as它的意思相当于“A事情发生以后，就做B这件事”。这个短语用的比较常用，口语和书面语都可以。它的特点是，在句子中的位置比较灵活，而且可以用于各种时态。例如：I'll write you as soon as I get there.我一到那儿就给你来信。（一般现在时）As soon as I went in, Katherine cried out with pleasure.我一进门，Katherine 就高兴的叫起来。（一般过去时）I'll return the book as soon as I have read it.我一读完就把书还回去。（现在完成时）Andrew left as soon as he had drunk his coffee.Andrew一喝完咖啡就走了。（过去完成时）b、no sooner…than它的意思相当于“刚做完A这件事，就做B这件事”。例如：He had no sooner returned than he bought a house.他一回来就买了一套房子。如果no sooner 位于句首，主句要用倒装结构。例如：No sooner had he arrived than he went away again.他刚到就又走了。No sooner had the game started than it began to rain heavily.运动会刚开始，天就下起了大雨。有一点要注意，no sooner…than 一般用来描述做过的事情，它不能用于表示将来的事。c、hardly…when...它的意思是“几乎未来得及做完A这件事，紧接着就开始B这件事。”使用这个短语时，一般用于过去完成时；并且when有时可改用before。例如：He had hardly finished the article when the light went out.他刚要写完文，灯就熄了。He had hardly had time to settle down when he sold the house.他还未安顿下来，就卖掉了那所房子。另外，如果把hardly放于句首，主句要用倒装结构即谓语动词要提前。如：Hardly had I finished eating when he came in.我刚吃完他就进来了。Hardly had she gone out when a student came to visit her.她还没走出家门，就有一个学生来看望她。
