题型：不详难度：来源：

We’d better not keep the lights______ when we have PE classes outside.

A．off

B．on

C．open

D．closed

答案

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
