Instantly  S + V , S + V

At + n. , S + V             ß前後主詞相同時

on / upon + Ving , S + V     ß前後主詞相同時 

As soon as I left home this morning, the phone rang. (我一離開家,電話就響了。)

The moment I left home this morning, the phone rang.

1. as soon as 為連接詞,引導副詞子句,修飾主要子句

As soon as I saw her, I knew there was something wrong.

 (我一看到她,我就知道不對勁了。)

這句主要是要表示有什麼事情不對勁,as soon as引導的看到她只是用來修飾什麼時候覺得不對勁。

2.用在未來時態上,as soon as 引導的副詞子句是條件句,故應採現在式,主要子句採未來式

As soon as S + 現在式V, S + will + V

As soon as he gets home, he will take a shower. (他一回家就會洗澡)

3. On/Upon + V1-­ing, S + V2 . . . 僅可使用於前後的主詞相同之時

Upon arriving in Taipei, I will give you a call. (一抵達台北我就會打電話給你)

抵達台北與打電話者為同一人,才能使用該句型

比較:

As soon as my mom left, my little brother began to cry.

(我母親一離開,我弟弟開始哭)

On leaving, my little brother began to cry. (X) 此為錯誤用法

前後主詞為不同人,不可以使用該句型,會導致語意錯誤 (我弟弟一離開,我弟弟開始哭)

 

注意此句型只用在過去式中

S + had + no sooner + Ved/3 than + S + Ved/2   ß比較級sooner後面連接詞用than 

 

= S +  had

hardly

pp

when

S + V

     scarcely                     before

They had hardly got to school when they began to study.

They had no sooner got to school than they began to study.

The had scarcely got to school before they began to study.

Scarcely + had + S + Ved/1  when + S + Ved/2    ß倒裝句

Hardly + had + S + Ved/1 when + S + Ved/2

No sooner  + had + S + pp   than  S + V

將否定部分no sooner移至句首,形成倒裝句,因此,必須將助動詞didhad移至主詞之前,表示某事緊接著另一件事發生,譯作「一…,就…」。

注意No sooner had + S1 + V1-­en + than + S2 + V2-­ed前後句的時態不同。該句型的前半部表示先發生的事,即「一…」的部分,使用過去完成式had V-­en;後半部表示接著發生的事,即「就…」的部分,使用過去式V-­ed,例:

No sooner had they got to school than they began to study.

Hardly/Scarcely had they got to school when/before they began to study.
