soon和in a hurry和at once

Question

He gave him the money immediately. He gave him the money ____ .
(a)soon
(b)in a hurry
(c)at once
答案是选at once，我也选对了，只是直觉觉得要选at once，但是soon和in a hurry都有“立刻，马上”的意思，为什么不能选呢？很疑惑，那位能帮忙分析一下，感恩戴德！！

Answer 1

soon "将快" "就快" 是未来的。这里 gave 是过去式，所以不合用。

in a hurry 是 "怱忙" ，可以用，但与 He gave him the money immediately. 不符。

而 at once 是 "立即" 的意思。
He gave him the money at once 他立即把钱给了的。 与 He gave him the money immediately. 同义。

Answer 2

这题目就是让你区分的，你知道问，就说明你明白了题的用意。不错不错。
下面我给你讲下
soon 表示时间之后 也就是一般用于时间方面，等同于shortly
而in a hurry 用在动作上，表示动作上的快。 同样的quickly 也是动作上的快
at once 就等于immediately了。本回答被提问者采纳
