We must not more lights than we need A turn on B turn off C put on D put off 说明理由

问题描述:

We must not more lights than we need A turn on B turn off C put on D put off 说明理由
We must not 空格more lights than we need A turn on B turn off C put on D put off 说明理由

选A
字面翻译:我们千万不要打开更多的灯比我们需要的.(别浪费电的意思)
turn on 打开; turn off 关上
put on 穿上;put off 推迟,取消
楼上说错了:take off的意思才是“脱下”
