题目内容
---How can I save the water?
---It’s easy. First, make sure the tap ____________ after using.
A. turns off B. is turned off
C. turns on D. is turned on
B
【解析】
试题分析:句意:-我怎样才能节约水?-这很容易。首先要保证在用完水后关上水龙头。turn off 关闭;turn on 打开。根据句意可知,用完水后要关上水龙头,故C和D不对;并且这里the tap和turn off构成被动的关系,应该用被动语态。故选B。
考点:考查动词的被动语态和动词短语辨析。
