being
1.for the time being是习语，作“暂时地”解，being是be的现在分词，用作形容词，作existing解。
2.I am sending you a cheque for ¥30.00, being the rent due on 15 May等句子里的being是商业文件里的习惯用法。不可用在其他文字里，如不可说I am sending you Mrs Gaskell's Cranford, being the book you asked to borrow the other day，该把being去掉，或把being the book改作which。
3.下面各句的开首都可以说省去了being：
- Written in simple English, the book is easy to read.
- Deeply interested in my work, he often gives me advice.
- Asked where he was going, the boy said he was just taking a walk.
- Curious, she tore the letter open.
- Nearly seventy years old, the author is as busy as ever.
- A skilled labourer, he is always ready to help others.
- An industrious student, he finds plenty of time for study.
- Unquestionably one of the greatest novels ever written, it is still widely read today.
4.下面两句里的being可有可无：
- The task (being) completed, they went home.
- Her children (being) away at school, she was alone at home.
但下面两句里的being通常不省去：
- He being away, she was alone at home.
- It being fine, we had a walk together in the park.
注意He和It都是代词。
下面两句里在gun和head后面没有being：
- They started for the wood, gun in hand.
- He jumped into the water head foremost.
注意gun和head前面都没有his。
