operate

1.下面各句里的operate和operated都有些美国英语味：

• They operate the school together.
• The theatre is well operated.
• I do not know how to operate a motor-car.
• This farm is operated by a hundred peasants.

在英国通常用conduct(ed), manage(d), run（或ran）, carry（或carried）on等。

下面各句里的operate和operated也都有些美国英语味：

• The school and the library operate under the same management.（在英国通常用are conducted）
• The doctor has operated in the city for years.（在英国通常用practised）
• This custom seems to operate in several places.（在英国通常用prevail）
• He operated in the negotiations with tact.（在英国通常用acted）

2.说“对于（人或身体的某部分）施行外科手术”在operate后面接on或upon。例如：

• The doctor operated (up)on me carefully.
• My right eye was operated (up)on for the detachment of the retina（视网膜剥离）on the afternoon of 9 October, 1956.

注意不可说The doctor operated (up)on the detachment of the retina或The detachment of the retina was operated (up)on，该说The doctor operated (up)on me（或my right eye）for the detachment of the retina和I（或My right eye）was operated (up)on for the detachment of the retina。

The doctor operated (up)on him carefully等句子里的on或upon美国人（尤其医生们）往往省去，不算正当。
