Question

英语翻译I was not unprepared for jagged rocks and treacherous,sh

Answer 1

I （主语）was（系动词） not unprepared（表语） for jagged rocks and treacherous shoals（状语） if I could only have change -- change and the excitement of the unforeseen（条件状语从句）.

我并非对参差突兀的岩石和变幻莫测的暗礁毫无防备,只要能让我有所改变的话——改变和对无法预知的外界的兴奋.

was not unprepared 是个双重否定.

if 引导条件状语从句.

破折号后面是解释性短语.
