受争议的英文

争论 [zhēng lùn] argument debate controversy contention to argue to debate to contend

controversial 其实有个词语也是同样意思 我觉得这个比较好：arguably

controversial意思：causing disagreement or discussion:a controversial issue/decision/speech/figure例句：The book was very controversial.

argue 或 debate

controvert 就是这个

argue ['ɑɡju:] vi. 争论，辩论；提出理由vt. 辩论，争论；证明；说服[ 过去式argued 过去分词argued 现在分词arguing ]
