What interested me most is where he won the final
系动词am is are后面跟的句子就是表语从句
主句What interested me most
但这里因该用that就行 不用where 不是问地点
如This is where i once lived这是我曾经生活的地方!这里用where引导表语从句
如果变成定语从句就是在This is后加个先行词the one就变成了This is the one where i once lived这个就是想表达地点 “令我最感兴趣的是他在哪里赢了决赛.”的确正如楼上所说的，是强调句1. It is / was + 被强调的部分 + that ( who, which ) + 句子的其他部分,2. What … is / was …这种句式就称为强调句。这是一个句型结构，有2种！你记住就行了！比如强调主语 It was Ann Peters' husband that (who) rushed her to a nearby hospital last night. 昨晚，正是安妮.彼德的丈夫，立即送她去了附近医院。 强调宾语 It was her (she) that (who) Ann Peters' husband rushed to a nearby hospital last night.昨晚安妮.彼德的丈夫立即送的是她，去附近医院。参加工作了，某些东西有些忘记了，请见谅！但是希望你记住这句型，因为以后很多中译英也要用到！英语中很多东西没有道理的，记住句型就行
