选C
be used to sth 习惯于某事
he was used to修饰the life ,意思是,他所习惯了的生活在那一年发生了改变,.
因为有时间状语那一年that year,所以动词使用过去式changed

C 本句应该填个谓语动词，that year 说明发生在过去 用一般过去时

主语是 the life ，
he was used to是The life 的修饰语，缺少谓语
而根据后面时态，可知是一般过去时，所以填changed

C，changed，主语 The life， 谓语 changed 。

选C，解析：当一个糟糕的交通事故发生在他身上，那年他所习惯的生活被改变了。一读便知是过去时态，而to后缺谓语动词，则填changed

he was used to是修饰The life 的从句，省略了引导词that，意为“他所习惯了的生活”可忽略不计，句子缺少谓语，根据that year 以及后文，知道应用过去式changed，
