Passed も Past も発音は同じ
どういう使い分け
Oxford Dictionaries のＨＰに解説がありました
（ＨＰ→O ）
passed is one of the forms of the regular verb to pass.
past is *never* a verb, so if you know that the word you want is a verb, passed is always the right choice. Conversely, if you need a noun, adjective, adverb, or preposition, it’s *got* to be past.
なるほど
Passedは、動詞の変化形。
だから、動詞のポジションに入れるなら、Passed
Pastは、いろんな品詞があるけれど、動詞ではない。
だから、動詞以外で使うなら、Past
【問題】下記の使い方は、正しいか。
This year has past so quickly for me. When I look back over the passed 12 months, I have mixed feelings. On the plus side, I past my final exams and qualified as an accountant. However, I was knocked off my bike when a bus past by me too closely, resulting in two broken ribs – ouch! But I’m putting the past behind me now, and looking forward to 2015.
