As soon as S+Ved, S+Ved 一 (S+V)就(S+V)
The instant S+Ved, S+Ved
As soon as he saw me, the infant cried.
The moment he saw me, the infant cried.
The instant/The minute he saw me, ….
Wait a sec (ond)!
No sooner had S+pp than S+ved
No sooner had the infant seen me than he cried.
No sooner had you seen me than you laughed.
No sooner had Mary smelled the food than she felt hungry.
Hardly/Scarcely had S+pp when S+ved
Hardly had you seen me when you laughed.
Scarcely had Mary smelled when she felt hungry.(瑪莉幾乎沒聞到食物就餓了)
