一手一 腳 做 完 一 件 事

基本上, '自己嚟' or '靠自己' 可以有3種講法:

1) on someone's own (adverbial phrase)
2) by oneself (adverbial phrase)
3) alone (adverb)

要強調 '全靠自己', 可以加 'all' 來加強語氣 ( 'alone' 除外); 所以 '一 手一 腳 做 完 一 件 事' 可以有以下講法:

e.g. I finish XX (something) all on my own.
e.g. He did XX (something) all by himself.
e.g. They have completed XX (the task) alone.


Additional useful example:

I can do it alone. 我可以獨自辦理此事。(this is quoted from yahoo dictionary)


請留意句子中的動詞 & 動詞的Tenses可因應情況需要而自由配合運用.

當然, 004 提供的 'by nobody but someone' (adverbial phrase) 及005 的 'solely' (adverb, same as 'alone') 同樣是很 common, 與我所提供的有異曲同工之妙.

From the very beginning up to the end, it is done by myself solely.
