解析
试题分析:句意:当我们在外面上体育课时,我们最好不要保持灯开着。keep sth on保持…开着。on 介词在这里作特殊用法相当于形容词,开着的。故选B. 点评:on 的特殊用法在中学英语中要进行了解,如下:1.继续 如:They talked on until midnight. 他们一直谈到深夜。 2.向前3.穿上,盖上,连接上It"s cold today. Why don"t you put your overcoat on? 今天很冷。为什么不把大衣穿上? 4.(机器)处于工作状态;开着;通着He left the engine on while waiting for Joe. 他在等候乔时让汽车引擎开着。 5.上演着;在进行中 |
