as soon as

as soon as

片語

片語摘要

•
as soon as:表示「一…就…」,強調動作緊接發生
•
文法重點:時間從屬子句用現在式談未來(不用 will)
•
常見用法:命令句、計畫安排、即時通知(如到站、下課)
•
常見變體:as soon as possible(ASAP)用於請求對方「儘快」

形式與用法

as soon as
1) 表示兩個動作幾乎連續發生,後子句通常立刻接在前子句之後。 2) 後面要接完整子句(主詞 + 動詞);不可只放名詞(錯:As soon as the exam.)。 3) 談未來時,as soon as 引導的從屬子句用現在式;主句可用未來式(I will call you as soon as I get home.)。 4) 當 as soon as 子句在句首時,子句末尾加逗號;主句在前時通常不加逗號。 5) 與 when 相比,as soon as 更強調「立即、緊接著」。
合併形式範例:
I will call you as soon as I get home.
我一到家就打給你。
其他形式:
as soon as possible
意思為「儘快」。常用於請求、指示或回覆。縮寫為 ASAP(較口語);正式寫作建議使用完整拼寫。
ASAP
為 as soon as possible 的縮寫,口語、訊息常見;正式考試或報告不建議使用。

常見錯誤

✗
I will call you as soon as I will get home.
✓
I will call you as soon as I get home.
時間從屬子句(as soon as 引導)談未來時,用現在式,不用 will。
✗
As soon as the exam, we went to eat.
✓
As soon as the exam ended, we went to eat.
as soon as 後面需接完整子句(要有主詞與動詞),不能只放名詞片語。
✗
We go to the gym, as soon as we finish dinner.
✓
We go to the gym as soon as we finish dinner.
當主句在前、as soon as 子句在後時,通常不需要逗號;逗號在此多餘。
✗
I’ll finish ASAP in my formal report.
✓
I will finish as soon as possible in my formal report.
ASAP 偏口語,正式寫作建議改用完整的 as soon as possible。

同義詞與反義詞

同義
once
(一旦)
語氣較中性,側重「條件一成立就…」,未特別強調「立刻」;常與 as soon as 可互換。
同義
the moment (that)
(一…就…;當…的那一刻)
口語色彩較強,語氣更生動;時態規則同 as soon as。
同義
right after
(在…之後立刻)
偏副詞/介系詞用法,常接名詞或動名詞(Right after class / right after finishing…),語氣非常即時。
同義
immediately after
(在…之後立刻)
語氣較正式,結構與 right after 類似,強調緊接發生。
同義
no sooner ... than
(一…就…)
較正式且需倒裝(No sooner had S p.p. than S V-ed),常用於書面或強調語境。
反義
not until
(直到…才)
表達「延後到某時才發生」,語義與 as soon as 的「立即」相反。
反義
only after
(只有在…之後才)
強調必須先完成前件,與 as soon as 的即時性相對。
反義
before
(在…之前)
描述相反的時間順序,無「立即」之意。
