Don’t leave the water ___ while you brush your teeth.| A．run | B．running | C．being run | D．to run |

答案
| B |
解析
试题分析：本题考查非谓语动词作宾语补足语的用法。单从结构看，无法确定本题答案，因为leave后的宾语补足语可以是done/doing/to do。结合语意“刷牙时不要让水一直淌”，只能用leave the water running，因为强调正在进行，run意为“流、淌”时是不及物动词，不能用于被动语态。
点评：解题思路，①解析句子结构，确定设空在句子中充当的功能（如状语、定语或宾补）；②找准相关动词的逻辑主语，确定该动词与逻辑主语是什么关系（主动还是被动）；③搜索句子中相关的时间信息，确定非谓语动词的恰当形式；④将该选项置入空中，看是否能够做到字从意顺，或是否能传达有效信息、完成交际任务。 |
