⒊垂悬不定式动词短语,如:
③ To write well, a lot of practice is needed.
④ 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,真正的主语必须是 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.
上述三类垂悬结构中,第一类发生的频率最高,必须注意。但是在下列三种情况下,分词短语是对的,它们并非垂悬结构:
第一,独立结构(The Absolute Construction,见3月7日《中英合谈》)中的分词短语有自己的主语,所以不是垂悬结构。例如:
① Such being the case, we can go home now./it is not wrong to call it a day.
第二,当分词含有介词或连词性质时,它不需要逻辑主语,所以没有垂悬问题存在。例如:
② Owing to a lack of funds, the project has to be discontinued.
③ 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,也不需要逻辑主语,因此也不存在着垂悬问题。例如:
