 ♣ 下面三个短语意思不同：
　
 ♣ 下面两个短语意思不同：
　

1. 她马上就来。
　［误］ She will come at the moment.
　［正］ She will come in a moment.
　［析］ at the moment意为“此刻”。“马上，立刻”应说in a moment.
2. 老师一进来，学生们就站了起来。
　［误］ The moment when the teacher came in, all the students stood up.
　［正］ The moment the teacher came in, all the students stood up.
　［析］ moment与定冠词连用可以用来引导状语从句，表示“一…就…”，但其后不能跟关系副词when，只能跟关系代词that，且that又常常省略。
3. 我希望我一进办公室他就能来。
　［误］ I'd like to see him in my office the moment he will arrive.
　［正］ I'd like to see him in my office the moment he arrives.
　［析］ the moment之后要用一般现在时表示将来，而不用shall〔will〕加动词原形。
4. 就在这时，门开了。
　［误］ In that moment the door opened.
　［正］ At that moment the door opened.
　［析］ 表示“就在这〔那〕时”时，介词at不可用其他介词代替。

1. moment表示的“短暂”比较模糊，可以说a/one moment（一会儿）; half a moment（稍等一会儿，马上）; several moments（片刻）等，但不能说five moments, eight moments等。
2. 英式英语中，尤其是公众场合政治鼓动者爱用的一种夸张说法at this moment in time（此刻），其实一般仅用at this moment或just now就很适宜。例如：
　At this moment, the phone rang.　就在这时，电话铃响了。

　［同义词］ flash, instant, gravity, important
