It was in 1897 that a European chemist called Dr Felix Hoffmann produced aspirin from this chemical. 句式分析:此句是强调句型“It is(was)+that(who)+句子的 其余部分”,句中强调 时间状语 in 1897。强调句型的特点是 把 It is(was) 和 that (who) 去掉, 如果剩余部分句子结构能还原 成一个 完整的句子 ,那么这个句子就是强调句,否则不是。 霍夫曼的欧洲 自主翻译: 正是在1897年,一位名叫费利克斯·

药剂师提取了这种化学物质,制成了阿司匹林。
