as soon as文法簡介

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)

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)

S + had + no sooner + Ved/3 than + S + Ved/2 

 (比較級sooner後面連接詞用than )

= S +  had  hardly + pp + when   +S + V

   S+  had   scarcely + pp +  before  + S + V

(注意此句型只用在過去式中)

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

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

=They had scarcely got to school before they began to study.

Scarcely + had + S + Ved/1  when + S + Ved/2    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did或had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.
