7、ill find a path.左拐,你会找到一条路的。4.作结果状语 现在分词作结果状语时,通常放在句末,中间用逗号隔开,表示一种顺其自然、意料之中的结果。*(2019全国卷)If you exercise out of doors,your body will learn to breathe more deeply,allowing even more oxygen to get to your muscles and your brain.如果你在户外锻炼,你的身体就会学会深呼吸,允许更多的氧气到达你的肌肉和你的大脑。*He fell down the stairs,landing i

9、d to the railway station,only to be told that the train had left.(意想不到的结果)他匆忙赶到火车站,结果被告知火车已经开走了。5.作伴随状语没有相应的状语从句可以转换,但可以转换成并列句。*They came into the classroom,singing and laughing.他们走进教室,边唱边笑。6.作让步状语*Working as hard as he could,he could not pass the exam.尽管很努力,他还是不能通过考试。7.方式状语Using the book,I find it

11、ne)。(1)当现在分词的动作与谓语动词的动作同时发生时,用分词的一般式。Walking in the street,I met an old friend of mine.我正在大街上行走时,遇到了一位老朋友。(walking和谓语动词met同时发生)(2)当现在分词的动作先发生,而谓语动词的动作后发生时,用分词的完成式。Having finished the letter,he went to post it.他写完信后就把它寄了出去。(having finished是先发生的,went是后发生的)2.现在分词的语态使用现在分词的主动形式还是被动形式,这主要取决于现在分词和句子主语之间的关

12、系。句子的主语就是分词的逻辑主语。Having been shown around the factory,they were very happy.(现在分词的被动形式)被领着参观了工厂后,他们很高兴。Having finished his homework,he went to bed.(现在分词的主动形式)完成了作业后,他上床睡觉了。【知识延伸】动词-ing形式的否定形式:not+doing与not having+done*Not knowing this,he didnt come.他不知道这件事,所以没来。*Not having made full preparations,we p
