3．某些表示时间的名词词组，如 the (very) moment ( = as soon as ), the minute ( = as soon as ), the instant ( = as soon as ), the day, the year, the morning, every time, each time, next time, the first time 等，也可以引导时间状语从句，如：

4．有些关联从属连词，如 no sooner … than / hardly … when / scarcely … when / barely …when 等，也能引导时间状语从句。

She had no sooner heard the news than she fainted. = No sooner had she heard the news than she fainted.
