1.形容词做原因状语,有无being区别不大:
Beingpoor,hecouldn'taffordaTVset.(现在分词做原因状语)
Poor,hecouldn'taffordaTVset.(形容词做原因状语)
Beingill,Istayedathome.(形容词做原因状语)
Ill,Istayedathome(形容词做原因状语)
但过去分词做原因状语时不可加being表示状态,加being表示正在进行的动作:
Madeofglass,thecupisfragile.
Caughtintherain,hegotwetallover.
Lostinthought,healmostranintothedarinfront.
Beinginterviewedbythereporters,themanagerhasnotimetoseeyou.
2.形容词做时间状语,不可以加being.
Youhadbettereatvegetablesfresh(=whentheyarefresh,不可用beingfresh)
Thefruitscan'tbeeatenraw.(=whentheyareraw,不可用beingraw)
3.做伴随状语时,形容词和过去分词(其实他们已经形容词化了)可以互换.但均不可加beingdone.
Hegothomelatethatnight,hungryandtired.
=Hegothomelatethatnight,hungryandweary.
Afterhisjourneyfromabroad,RichardJonesreturnedhome,exhausted.
=Afterhisjourneyfromabroad,RichardJonesreturnedhome,weary.
4.做方式状语时,不可以加being.但他们可以加-ly.
Braveandstrong,theactiviststalkedtoworkersoutsidethefactory.(SB2P15)
Bravelyandstrongly,theactiviststalkedtoworkersoutsidethefactory.
Nervous,shetoreopentheletter.
Nervously,shetoreopentheletter.
Helpless,wewatchedthehousebeingdestroyedbeforeoureyes.
Helplessly,wewatchedthehousebeingdestroyedbeforeoureyes.
综上所述,形容词除了作原因状语,其他情况下一般不加being.而过去分词表示状态时一般也不加being(除非表示“正在被...”)
