___ to complete the job on time,they set out to work immiatelyA.determined (分词作状语,这里determine的逻辑主语和主句的逻辑主语是一致的,是表示主动的.但是要考虑决定做某事这个句型是be determined to do sth ,其实可以当作省略了because they were ,可以理解为原因状语从句.所以这里仍然用determined,而不用determining)B.To be determined (不定时作目的状语,有一年高考考了To sleep late in the morning,Bob turned off the alarm.(NMET 2001))纠结

问题描述:

___ to complete the job on time,they set out to work immiately
A.determined (分词作状语,这里determine的逻辑主语和主句的逻辑主语是一致的,是表示主动的.但是要考虑决定做某事这个句型是be determined to do sth ,其实可以当作省略了because they were ,可以理解为原因状语从句.所以这里仍然用determined,而不用determining)
B.To be determined (不定时作目的状语,有一年高考考了To sleep late in the morning,Bob turned off the alarm.(NMET 2001))
纠结

楼主分析的已经比较详尽了,这道题应该选择A,是出于语义上的考虑.
对于A选项,这里并不是because they were determined省略,而是 determined 这里是过去分词化的形容词, 表示“坚定的”,这个形容词修饰句子的主语 they,做整个句子的状语.类似的用法还有:
Happy to hear the news, I can't help smiling. 我非常高兴地听到这个消息,我忍不住微笑起来.
而B选项翻译出来就是,为了使自己下定决心按时完成工作,他们立即开始工作.
感觉上不如: 他们已经下定决心了要按时工作,所以他们立马开始工作.也就是A选项的翻译.
希望能帮到你O(∩_∩)O
