[译] 他昨天的化学实验未能成功。
[误] His chemical experiment failed in success yesterday.

[正] His chemical experiment failed of success yesterday.
[注] 动词 fail 作"失败"解时，如果主语是事物，后跟介词 of, 如: The proper use of the drug never fails of its efficiency. 适当使用此药，总是有效的。如果主语是人，须用介词 in, 如: He failed in his chemical experiment yesterday. 他昨天的化学实验未能成功。
