As the cost of wireless service has steadily dropped over the last year and as mobile phones have become increasingly common, many people are finding that they can avoid toll charges on their home （phones by using their mobile phones to make long-distance calls at night or on weekends, when） many wireless compaies provide unlimited airtime for a small monthly fee.
错误项：(phones using mobile phones for making long-distance calls during night or weekends, when)
Scientists believe that unlike the males of most species of moth, the male whistling moths of Nambung, Australia, call female moths to them （using acoustical signals, rather than olfactory ones, and attract） their mates during the day, rather than at night. (by using acoustical signals, not using olfactory ones, and by attracting)
Q:这里的by为什么不能省？ A:By using避免了using的发出者歧义。 错误项they can avoid toll charges on their home phones using mobile phones ……中using的发出者既可以是they，也可以是分词做从句修饰phones和charges，从而产生了歧义。 By using就避免了该问题，明确了主语发出者是They而非其他。

我的問題如下: 舉一個例子: 2*managers can decide on a strategy using the set of objective criteria.
請問這個的using就不會歧義? using 也可以修飾 前方的N(a strategy) 或 managers?

麻煩可以再針對這二句話做解釋嗎??? 對於歧不歧義還是抓不住重點...

Q:請問這個的using就不會歧義? using 也可以修飾 前方的N(a strategy) 或 managers? A:会 using是that/which/who be using的省略缩写形式 还原后，则既可以是who are using(此时修饰唯一复数managers)，也可以是that is using（be的单复数决定了修饰对象必为单数strategy），从而产生歧义
若改为: 2*managers can decide on a strategy by using the set of objective criteria by修饰唯一谓语decide表方式，共享逻辑主语managers，从而避免了歧义
