【句子】Stefan is a big part of that. 【The Vampire Diaries-S1E3】
【发音】[stefən] [ɪz] [ə] [bɪg] [pɑ:(r)t] [əv] [ðæt]
【发音技巧】big part 这里的[g] [p]完全失去爆破；
【翻译】Stefan起了至关重要/举足轻重的作用。
【适用场合】英语当中play a big part in sth. 或者把play换成is也可以，表示to serve as a major part of some situation or event.
说到重要大家肯定想到的词有：important，其实还有别的：crucial；significant, major 等等都可以，所以学英语要学会同义词替换。
