一般说来，分词用作状语时，它的逻辑主语必须与句子主语一致，但事实上也有少数例外的情况，它们的逻辑主语虽然与句子主语不一致，但它们却是合乎英语习惯的。这类特殊情况主要有以下几类：
(1) 表示观点的惯用表达
某些表示说话人态度的一些惯用分词表达，它们在用作状语时其逻辑主语可以与句子主语不一致。如：
Generally speaking, a promotion means higher salary and more responsibility.
一般而言，升职意味着更多的薪水和更大的责任。《外研社英语同义词辨析词典》
Generally speaking, all living things are sure to die without food.
一般来说,没有食物,所有的生物都会死。
Generally speaking there was no resistance to the idea
一般说来，没有人会反对这个观点。《柯林斯高阶英汉双解学习词典》
Generally speaking, we enjoyed the trip. 总的来说，我们这次旅行很愉快。
Strictly speaking, the book is not a novel, but a short story.
严格说来，这部小说不能算长篇，而是短篇。《牛津高阶英汉双解词典》
Strictly speaking, this was against the rules.
严格地说，这是违规的。《柯林斯高阶英汉双解学习词典》
Strictly speaking, you ought to sign the visitors’ book first. 严格讲，你应先在访客簿上签名。
Judging from everything you've said, it was just as well she wasn't there.
从你所说的这一切来看，幸好她不在那儿。《柯林斯高阶英汉双解学习词典》
Judging from the way he laughed as he told it, it was meant to be humorous
从他讲这件事时笑的样子来看，那应该是很幽默的了。《柯林斯高阶英汉双解学习词典》
Judging from the look of the sky, we'll have a rain this evening. 从天色来判断，今晚应该会下雨。
Judging from his tone, there's no doubt he is against it.
听他的话音，便知他是反对的。《汉英大词典》
She's very active, considering her age.
就她的年龄来说，她是十分活跃的。《牛津高阶英汉双解词典》
Considering his abilities, he should have done better. 以他的能力来看，他应该可以做得更好一些。
Taking everything into consideration, they ought to be given another chance. 若把一切都考虑进去的话，应该再给他们一次机会。
以上各句句首的分词短语的逻辑主语均与句子主语不一致，严格说来，它们的逻辑主语到底是谁都不是很明确，这类结构只是用于引出说话人希望表达的一种观点或态度。有的时候可以直接把这类词看着是介词。
(2) 含有先行主语it或there时
当句子含有先行主语 it 或 there 时，有时有作状语的分词短语可以与先行主语不一致。如：
Having so little time, there was not much that I could do. 由于时间很少，我能做的事很有限。
Being French, it's surprising that she's such a terrible cook. 她是法国人，但她做饭做得那么糟真是令人感到惊奇。
第一句的分词短语 having so little time 的逻辑主语应该是“我”，但由于句子主语是there，所以这句话也是可以接受的；第二句中的分词短语 being French 的逻辑主语应是“她”，但由于句子主语是it，所以这是合乎习惯的。
(3) 已转化成其他词类时
当分词转化为介词或连词，本身不再被视为分词时，我们就无需考虑其主语的一致性了。如：
Supposing you fell in love with your boss, what would you do? 假定你爱上了你的老板，你会怎么办?
Given their inexperience, they've done a good job. 考虑到他们没有经验，这工作已做得很不错了。
第一句中的supposing在此已不是分词，而是用作连词，相当于if；第二句中的given在此也不是分词，而是介词，其意为“考虑到”。所以这两句都无需考虑主语的一致性问题。
(4) 当逻辑主语为表示的one或you时
当分词暗含的逻辑主语为表示泛指意义的one或you时，也无需考虑主语的一致性问题。如：
In doing such work, patience is needed. 做这种工作需要耐心。
Using the electric energy, it is necessary to change its form. 我们使用电能时须改变其形式。
第一句中doing的逻辑主语应该是表示泛指意义的we或one，可考虑改写为：When one does such work, patience is needed. 第二句中using…的逻辑主语也是表示泛指意义的we或one，句子也可改写为：When we use the electric energy, it is necessary to change its form.
