as soon as 怎么用啊，词组相当于一个一般放在句子中的什么位置？

Question

如题所述

Answer 1

as soon as 这个词组在句子中的位置相当于立即、立刻或一…就，它可以连接一个时间状语从句，相当于"the minute/moment/second + 主句"或"no sooner than/hardly when"，其中否定词需放在句首进行部分倒装。例如，"No sooner had I arrived home than I did my homework"。

as soon as 的用法主要体现在描述两种情况：一是描述未发生的动作，其结构为主句用一般将来时，从句用一般现在时。比如："I will tell him the news as soon as he comes back." 如果想强调刚刚完成某事就如何，可以改用现在完成时："I will go with you as soon as I have washed my face."

二是描述紧接着发生的两个动作，不论主句还是从句都采用一般过去时，如"He took out his English books as soon as he sat down." 有时，即使从句的动作发生在主句之后，如果强调两动作的紧密连接，也可以用现在时："As soon as he finishes his classwork, he runs out of the class."
综上所述，as soon as 通常位于句首，引导一个时间状语从句，根据语境的不同，可以调整主从句的时态，以清晰表达动作的先后关系。
