首页 有逗号时,doing/dong动作 的发出者为S,这个时候doing做状语。
没有逗号时,doing/dong动作的发出者为O,这个时候doing做定语。
因为,分词短语具有形容词性和副词性两种功能。起副词性作用时用作状语(时间、原因、条件和伴随方式),起形容词作用时用作后置定语,相当于定语从句的省略。比如:Could you please translate the sentence beginning with "Far"? 在这里,分词短语 beginning with "Far"做sentence的后置定语,用来修饰 the sentence。用定语从句可以改写如下:Could you please translate the sentence (which begins with"Far")?
例句1: In the early eighteenth century, English poets and painters imagined the countryside filled with filled with shepherds enjoying a life of leisure and drawing on nature's bounty for their sustenance.
A. enjoying a life of leisure and drawing
B. enjoying a life of leisure, and they draw
C. who were enjoying a life of leisure, to draw
D. who enjoyed a life of leisure, then they drew
E. they enjoyed a life of leisure to draw
解析:划线部分前面没有逗号,说明是现在分词做后置定语修饰前面的shepherds,所以是说那些牧羊人享受生活乐趣和汲取大自然的富饶维持生计,A选项没有问题。B选项,they指代不清,不知道他说的是英国的诗人和画家,还是牧羊人。C选项,to draw表目的,不符合句意。D同样they指代不清。E选项they和前面的shepherds重复。
另外需要注意的一点事,现在分词完成式不能做定语,看下题:
例句2: The annual National Concrete Canoe Competition attracts teams of engineering students having designed canoes that promote the versatility of concrete.
A. having designed
B. who have designed
C. for designing
D. to be designing
E. and they designed
解析:这道题的意思是,一年一度的国家水泥轻舟比赛吸引了那些设计了这些独木舟旨在提高混凝土的多用性的工程院的学生队伍。A选项中的现在分词完成式不能做定语,C,D表将来,不符合句意,E选项没有B选项简洁。
在另一方面,现在分词状语,SVO, doing有两种情况:
1.做伴随状语,表同步发生,其逻辑主语是主句主语S:I walk into my office,singing a song。
2.做结果状语,SVO, thus/thereby doing, 这里的doing,修饰SVO整句话,其逻辑主语是前面的句子,说明前面这句话的结果。
例句3:Textile production has a serious environmental impact, it consumes a significant amount of all the water used worldwide.
A. It consumes
B. Its Consumption is
C. this consumes
D. consuming
E. it has consumed
解析:A, B,E选项是run-on sentence,肯定不对。C选项this 不能单独指代,且也是run-on sentence,D选项consuming前有逗号,所以做结构状语,修饰整个句子。
