3. Among the painters who broke away from the traditional style of painting were the Impressionists.
突破传统绘画风格的画家中包括了印象派画家。
[解释] 本句为倒装句，原语序为：
The Impressionists were among the painters who broke away from the traditional style of painting.
本句结构为“介词短语+连系动词+主语”（倒装语序）
在英语语法中，当介词短语/形容词/分词提到连系动词前面时，句子要求采用全部倒装。构成“介词短语/形容词/分词+连系动词+主语 ”（倒装语序）全部倒装是只将句子中的谓语动词全部置于主语之前。
