no sooner than 和hardly when以及as soon as的区别：no soon...

no sooner than 和hardly when以及as soon as的区别：no soon. 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. as soon as, hardlywhen no soonerthan 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. 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。 1、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： Ill 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） Ill 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） 2、no soonerthan 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 soonerthan 一般用来描述做过的事情，它不能用于表示将来的事。 3、hardlywhen. 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 h
