The –ing form as the Adverbial
(动词ing用作状语)
现在分词用作状语
现在分词作状语（修饰动词）时, 可表时间、原因、条件、方式、伴随、让步等情况。
1.现在分词作时间状语
现在分词作时间状语时，相当于时间状语从句。可在现在分词前加连词“when, while, until”等，使其时间
意义更明确。
Walking in the park, she saw an old friend.
分析：walk的动作是由其逻辑主语“she”发出，与句子的主语she一致，且构成主动关系，所以用动词-ing形式。
＝When/while (she was) walking in the park, she saw an old friend.
2.现在分词作原因状语
现在分词作原因状语时，可转换为由since, because或as引导的原因状语从句，这类状语多放在句子的前半部分。
Being ill，he couldn't go to school.
＝As he was ill，he couldn't go to school.
3.现在分词作条件状语
现在分词作条件状语时，可转换为if, once或unless等引导的条件状语从句。
Working hard，you'll make great progress.
＝If you work hard，you'll make great progress.
4.现在分词作让步状语
现在分词作让步状语时，相当于一个以though/although引导的让步状语从句。
Working or reading，she always did her best.
＝Whether she worked or read，she always did her best.
5.作方式\伴随\结果状语
现在分词作方式、伴随和结果状语时，说明动作发生的背景和情况。作伴随状语时，表示分词的动作和主句的动作同时发生，此时它可转换成并列句。
Using a stick, the painter drew a picture on the ground.
=The painter drew a picture on the ground by using a stick.
Mary sat by the window of the classroom, reading a book.
=Mary sat by the window of the classroom and was reading a book.
His parents died, leaving him an orphan.
＝His parents died and left him an orphan.
特别提醒:
1) 为使动词-ing作状语所表达的时间;条件;让步等更明确,可在动词-ing形式前加上适当的连词(when, while, though, unless, if, even if等)
1.吃饭时不要说话。
Don’t talk while having dinner.
2.一旦失去这次机会你 就很难找回。
Once losing this chance, you can’t easily find it.
2) 动词-ing形式作状语时,其逻辑主语必须与句子的主语一致.
1. Looking out of the window, the garden was beautiful.
Looking out of the window, we found the garden beautiful.
2. While reading the book, the telephone rang.
While she was reading the book, the telephone rang.
3)当--ing表示的动作发生在谓语动词之前时,应使用完成式: having done. 否定式在前加not.
1. 做完了作业，他冲出去打篮球。
Having done his homework, he rushed out to play basketball.
2. 写好了信，他出去邮寄它。
Having finished the letter, he went to post it.
3. 由于没有认真学习，他考试失败了。
Not having studied his lessons very hard, he failed the test.
4) 当--ing与句子的主语存在逻辑上的动宾关系时,-ing分词要用被动形式。
1. Having been criticized by the teacher, he gave up smoking.
2. Being questioned by the teacher, she felt
very upset.
5) V–ing 用于某些固定搭配中,表示说话人的态度;观点等,如:generally speaking, frankly/honestly speaking, judging by/from, considering/seeing, supposing等
1. Generally speaking, girls are more careful than boys.
2. Supposing it rains, we will put off the sports meeting.
3. Judging from his accent, he must be from the north.
6) 现在分词和过去分词做状语的区别。
