关于伴随状语的位置问题

不是版主君...但希望能夠幫到你啦;)~

根據manhattan所說，present participle要分成without comma和with comma兩個不同類型分析：
1、present participle without comma——作為noun modifier，根據touch rule原則修飾最近的noun
2、present participle with comma——作為verb modifier/adverbial modifier，修飾規律如下【by Ron】
1)if comma + -ing follows a clause, it should describe the action (and, at least indirectly, the subject) of that clause. This is in fact the entire reason for the existence of this construction,
2)if comma + -ing DOESN'T follow a whole clause -- if it just follows a noun -- then it will modify only that noun.
E.g. tom, trying to reach all the way across the table, lost his balance.
3)if a comma + -ING modifier follows a complex expression that has more than one subject+verb pair, then you may have to use a certain amount of common sense to distinguish what is modified. The modifier still must modify the same rules, but could refer to either of the subject/verb combinations.【就是說主句裏面含有從句，使得主句的[subject + verb] > 1 pair，這種情況下present participle with comma修飾的是哪個pair的[subject + verb]，需要meaning和common sense來確定】
e.g.
i carried a bag containing six incubators that enclosed baby chicks, supporting them with nutrients and heat.
here, the comma -ing modifier modifies only the second subject+verb pair. shown in color:
i carried a bag containing six incubators that enclosed baby chicks, supporting them with nutrients and heat.【這裡就是修飾從句的[subject + verb]！】

VS.
i dropped a bag containing six incubators that enclosed baby chicks, breaking two of them and endangering the chicks' lives.
here, the comma -ing modifier modifies the entire preceding clause. shown in color:
i dropped a bag (containing six incubators that enclosed baby chicks), breaking two of them and endangering the chicks' lives.【這裡就是修飾主句的[subject + verb]！】
