[译] 老师指导我们如何做试验。
[误] The teacher guided us how to carry out the experiment.

[正] The teacher guided us in carrying out the experiment.
[注] 根据 guide 的用法要求，它不能用于 guide sb. how to do sth. 这种跟动词不定式复合宾语的结构中。所以表示“指导某人做某事”，应该说 guide sb. in doing sth.。如：The policeman guided the pupils across the street. 警察引着学生横过街道。
