------- in the office,he decided to change a job.(tired) 由于厌

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也是非谓语动词.
如果要用从句来说也可以：
Because he was tired of the work in the office,he decided to change a job.
Because he was tired of working in the office,he decided to change a job.
由于这个从句表达的是他决定换工作的原因,所以是原因状语从句.
不明白的再问哟.
再问： ___________________________ 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？
再答： 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。
再问： 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/
再答： 是的。形容词可以直接作状语用。
