IN ORDER TO DO 可以放在句首,比较正式,表示“为了做...”(1)比单纯的TO DO 更强调"目的".(2)为表TO以下不定式的意义上主语(实质上主语),亦可将FOR+(代)名词至于TO DO之前.
SO AS TO DO 表"为了(做)...;做..."与IN ORDER TO DO 的区别在于前者有为下一步动作做解释的意思.
EG.HE WORKED HARD SO AS NOT TO FAIL THE MATH EXAM.
注意区分SO AS TO DO与SO...AS TO DO的用法,后者表示到...程度.
EG.SHE WAS SO KIND AS TO HELP THE OLD LADY OFF THE BUS.
