语法精析
一、动词的-ing形式作状语可以表示时间、原因、条件、结果、让步、方式或伴随情况等。
1.时间状语
动词的-ing形式作时间状语，相当于一个时间状语从句，所表示的动作与主句的动作一般是同时发生，有时可由连词when，while，after引出。
(1)Hearing the result(＝When I heard the result)，I couldn’t help jumping.
听到这个结果，我不禁跳了起来。
(2)Having made full preparations(＝After we have made full preparations)，we are ready for the examination.做了充分的准备之后，我们准备参加考试。
2.原因状语
可以与as/since/because等引导的原因状语从句转换。
(1)Being so excited(＝As he was so excited)，he couldn’t go to sleep that night.
由于非常激动，那晚他没睡着。
(2)Having lived in the city for many years(＝Since I had lived in the city for many years)，I knew it well.
因为在这个城市住了多年，所以我对它很了解。
3.条件状语
可以与if/unless等引导的条件状语从句转换。
(1)Working hard at your lessons(＝If you work hard at your lessons)，you will succeed.如果你努力学习，就一定能成功。
(2)Not making good use of the time(＝If you don’t make good use of the time)，you’ll regret.如果不好好利用时间，你会后悔的。
4.方式或伴随状语
不可以转换成从句，但可以转换成并列句。
(1)The girls came into the classroom，singing and dancing(＝and they sang and danced).女孩子们唱着跳着进了教室。
(2)He lay on the grass，staring at the sky for a long time(＝and stared at the sky for a long time).他躺在草地上，长时间地望着天空。
5.结果状语
表示必然的结果，它常常位于句末，可扩展为一个含有并列谓语的简单句，有时也可以转换成非限制性定语从句。
His father died，leaving him a lot of money(＝and left him a lot of money/which left him a lot of money).他父亲死了，留给他许多钱。
6.让步状语
可以与although/though引导的让步状语从句转换。
(1)Knowing all this(＝Although they knew all this)，they made me pay for the damage.尽管知道了一切情况，他们还是要我赔偿损失。
(2)Having made up my mind(＝Though I had made up my mind)，I still wanted to play.尽管我已下定决心，我仍然想玩。
二、动词-ing形式作状语的注意事项
1.逻辑主语
动词-ing形式作状语，其逻辑主语一般就是句子的主语，它们之间是一种逻辑上的主谓关系。
Being ill，he didn’t attend the wedding.
因为生病，他没有出席婚礼。(he与being ill是逻辑上的主谓关系→He was ill.)
2.独立结构
有时现在分词有自己的逻辑主语，这时其逻辑主语相对于句子的主语来说是独立的，因此又叫独立主格结构，其构成形式是“名词/代词＋v.-ing”。
She being ill，her mother had to look after her at home.
她生病了，母亲不得不在家照顾她。
The meeting being over，we went to play football.
会议一结束，我们就去踢足球了。
