⒊垂悬不定式动词短语，如：
To write well, a lot of practice is needed.
To be a loyal employee, a sense of belonging is a must.
这两个句子的不定式动词短语(infinitive phrases)并不能修饰“practice”和“a sense of belonging”，真正的主语必需是“ 人”，如：
(a) To write well, one needs a lot of practice/a person has to practise a lot.
(b) To be a loyal employee, he or she must have a sense of belonging.
上述三类垂悬构造中，第一类发生的频率，必需留意。但是在以下三种状况下，分词短语是对的，它们并非垂悬构造：
第一，独立构造(The Absolute Construction，见3月7日《中英合谈》)中的分词短语有自己的主语，所以不是垂悬构造。例如：
Such being the case, we can go home now./……it is not wrong to call it a day.
其次，当分词含有介词或连词性质时，它不需要规律主语，所以没有垂悬问题存在。例如：
Owing to a lack of funds, the project has to be discontinued.


Provided that there is sufficient time, everyone can do the job better.
第三，当分词短语是用来表示说话者的态度或意见时，也不需要规律主语，因此也不存在着垂悬问题。例如：
Judging from his facial look, the news must have been terrible.
Taken as a whole, there is nothing wrong with the logic behind that idea.
