下面两个句子都可以：Tired of the work in the office,he decided to change a job.Tired of working in the office,he decided to change a job.前一半不是从句,而是过去分词短语作原因状语.因为它没有主语,tired...___________________________ in the exam, he didn’t dare go home. (fail)因为考试没及格，他不敢回家。这个怎么填呢？这两个题有什么区别呢？可以填Having failed。 fail与逻辑主语"he“是主动关系，所以用主动形式的having failed。而上一题中的tired是形容词，故不能填having tired，只能只填tired，也可以填being tired。worried about the journey, I was unsettled for the first few days. 这个worried 也是形容词吧？是不是和tired是一样的道理，那这种是形容词的什么用法呢/是的。形容词可以直接作状语用。
